PHYSICAL CHARACTER.: The majority of the site is being farmed. An Ag/Urban wetland is located along the west side of the property and a Natural wetland is located at the southeast corner of the site. Mature trees are concentrated within the southeast corner and easterly edge of the wetland. The site generally slopes from southwest to northeast and from northeast to southwest, with the low points in the center of the site. Md will Mr. rm 4, hi - �, III ■ FEE II Brenden Pond �Y August 17, 1994 Page 2 j i On September 1994, the Planning Commission reviewed and recommended approval of this applicatioq. before the Planning ', There have been numerous revisions made since this item first appeared Commission on August 17, 1994. Consequently, this report has been ' modified to reflect these changes. The applicants have been very cooperative to incorporate the requested changes from the , Planning Commission and staff. PROPOSAL/SiIMMARY The applicant is proposing to subdivide 25.85 acres into 19 single family lots. The property is ' zoned RR, Rural Residential and the proposal calls for rezoning it to RSF, Residential Single Family. The average lot size is 24,956 square feet with a resulting gross density of 1.2 units per acre. The site is located north of Hwy. 5, east of Hwy. 41, and south of Minnetonka Middle School West. Access to the subdivision will be provided via an extension of Lake Lucy Road which ' will connect this subdivision with Highway 41 to the west and Galpin Boulevard to the east (through the Ryl n property). A cul -de -sac, Pondview Court, extends north to service all of the proposed lots with the exception of Lots 1, 2, and 3, Block 1. I All of the proposed lots meet the minimum area, width, and depth requirements of the Zoning Ordinance. There are four outlots shown on the plat. Outlot B is reserved for further subdivision and future development. Outlot C contains a Natural Wetland, and Outlot D is a remnant lot created as a result of the alignment of Lake Lucy Road. Outlot A will contain a private street to provide acce s and utility service to the Mancino property located to the east of the subject site. The site has a dense concentration of mature trees along the easterly edge of the wetland and ' northwest of Outlot C. The majority of the trees northwest of Outlot C will be lost as a result of the extension of Lake Lucy Road, however, the applicant will be required to replace them. The proposed 7oodland management plan submitted by the applicant addresses some of the ' reforestation issues. Additional trees will be required to meet ordinance guidelines. A 30 foot wide preservation easement located to the east of Lots 14, 15, 16, 17, Block 1, and Lots 1, and 2, Block 2 is proposed over the wooded areas. This easement will prevent any construction from , taking place and subsequently preserving the trees. In reviewing thi� plat, staff also had to look at access to the Mancino parcel to the east. While the Mancinos are not ready to develop or subdivide at this time, staff has asked them to give consideration ash to how their property will be developed. Staff wanted to ensure that the ' Mancinos are not land locked. A private road will be constructed on Outlot A to service the Mancino prope y as reflected in the revised plans submitted August 30, 1994. w, Brenden Pond August 17, 1994 Page 3 In summary, staff believes that the proposed subdivision is well designed. Minor revisions will be required. We are recommending that it be approved with conditions outlined in the staff ' report. BACKGROUND Gestach/Paulson has been working ith staff to develop this subdivision for couple of ears. g P a P Y The major stumbling block has been the location of Lake Lucy Road. A public hearing was held ' at the City Council's regular meeting on April 12, 1993 concerning the feasibility study for the extension of Lake Lucy Road between Trunk Highway 41 and Galpin Boulevard. This project ' was initially petitioned by two property owners, the Westside Baptist Church and property owned by Gestach/Paulson/Klingelhutz, amassing nearly 36 acres immediately east of Trunk Highway 41. During the process of preparing the feasibility, it became apparent that the Westside Baptist Church no longer had an interest in this project and had subsequently rescinded their project petition. Since the road needed to cross through the church property in order to serve the Gestach/Paulson/Klingelhutz property, the church's lack of participation for all intents and purposes had temporarily stalled the project. As such, the public hearing was tabled indefinitely. ' The renewed impetus for the Lake Lucy Road extension is the petition/support of this project by the two immediately affected property owners (Jerome Carlson located adjacent to Trunk ' Highway 41 and the Gestach/Paulson proposed development located immediately east of the referenced Carlson property). The project consists of the construction of Lake Lucy Road from Trunk Highway 41 east approximately 1400 lineal feet as an urban roadway with concrete curb ' and gutter, storm sewer and trail and the installation of watermain and sanitary sewer. The proposed road alignment for this project has been revised from the two alternative alignments presented in the original feasibility study. The currently proposed alignment would follow more ' closely with the existing Lake Ann Interceptor easement through the Carlson property and would reduce grading and tree loss impacts from that of the previously presented alignment options. The proposed plat is consistent with the Lake Lucy Road street and utility project. ' REZONING The applicant is proposing to rezone the property from RR, Rural Residential to RSF, Residential Single Family. The area to the east, west and south is zoned Rural Residential and is guided for Residential Low Density. The area to the north of the site is zoned Office Institutional and contains the Minnetonka Middle School West. The 2000 Land Use Plan shows this area designated for development as Low Density Residential, 1.2 - 4.0 units per acre. The applicant's proposal has a gross density of 1.3 units per acre and 1.75 units per acre net after the streets and wetlands are taken out. LJ Brenden Pond ' August 17, 1994 Page 4 This area is in t the MUSA area. Staff is recommending that this area be rezoned to RSF and the rezoning is consistent with the Comprehensive Plan. ' The applicant is proposing to subdivide a 25.85 acre site into 19 single family lots. The density of the proposed subdivision is 1.3 units per acre gross, and 1.75 units per acre net after removing the roads and wetlands. All the lots exceed the minimum 15,000 square feet of area, with an average lot size of 24,956 square feet. ' All of the proposed lots meet the minimum width, and depth requirements of the Zoning Ordinance. There are four outlots shown on the plat. Outlot B is reserved for further subdivision ' and future development. Outlot C contains a Natural Wetland, and Outlot D is a remnant lot created as a res�lt of the alignment of Lake Lucy Road. Outlot A will contain a private street to provide access to the Mancino property located to the east of the subject site. Staff notes that the proposal is consistent with the Comprehensive Plan and generally consistent with the Zoning Ordinance. WETLANDS ' According to the wetland delineation performed by Westwood, two wetlands have been identified on -site and they are described as follows: , West Basin is an ag/urban wetland located along the central portion of the western boundary of the site. About half of the wetland extends off -site to the west; approximately 5.17 acres of , wetland is on site. This wetland is DNR protected water, 10 -132W. An ordinary high water mark has not been established for this wetland. ' Southeast Basin is a large natural wetland located m the southeastern corner o f the property. The majority of the wetland is off -site with only approximately 2.03 acres on -site. It does not appear that the wetland will be impacted as a result of construction of Lake Lucy Road, however, , it is very important that type III erosion control be constructed around the wetland and well maintained dung construction. There will be some fairly steep side slopes (3:1) adjacent to the wetland. A pot ntial erosion problem exists; therefore, the side slope should be revegetated as ' soon as possible after site grading with erosion control blanket. This area will be constructed under the City's improvement project and will be addressed on the construction plans. ' Regulations The City admin Isters the Wetland Conservation Act (WCA), however it does not appear that a ' wetland replacement plan will be necessary for this project. Staff would like the following Brenden Pond August 17, 1994 Page 5 information as part of the wetland delineation report: a map with the locations of the wetland data points, at least one data sheet for each wetland identifying upland, and a map of the soils. In addition to the requirements of the WCA, the City also requires a buffer strip and buffer strip ' monumentation around the wetlands. The buffer strip width required for natural wetlands is 10 to 30 feet with a minimum average width of 20 feet and the buffer strip width required for an ag/urban wetland is 0 to 20 feet with a minimum average width of 10 feet. The principal structure setback for these wetlands is 40 feet measured from the outside edge of the buffer strip. SURFACE WATER MANAGEMENT PLAN (SWMP) ' The City has prepared a SWMP that is in the final stages of formal adoption. The SWMP will serve as a tool to protect, preserve, and enhance its water resources. The plan identifies the stormwater quantity and quality improvements from a regional perspective necessary to allow future development to take place and minimize its impact to downstream water bodies. In general, the water quantity portion of the plan uses a 100 -year design storm interval for ponding ' and a 10 -year design storm interval for storm sewer piping. The water quality portion of the plan uses William Walker Jr.'s Pondnet model for predicting phosphorus concentrations in shallow water bodies. An ultimate conditions model has been developed at each drainage area based on projected future land use, and therefore, different sets of improvements under full development were analyzed to determine the optimum phosphorus reduction in priority water bodies. ' In conjunction with final platting and the construction plan review process, staff will require the applicant to supply drainage plans providing the pre - developed and post developed drainage areas along with runoff calculations for pre - developed and post - developed conditions. Storm water ' runoff from the site shall maintain the pre - developed conditions for a 100 -year, 24 -hour storm duration. Water quality ponds will not be required since this development will connect to the ' City's construction project. the applicant will be assessed for storm drainage improvements in lieu of SWMP fees. Storm water discharge to the ag/urban wetland will be pretreated in a sedimentation pond to be constructed with the City's project. Detailed drainage plans and calculations indicating drainage to individual catch basins will also be required. The grading plan shall also reflect the normal and high water elevations in the wetlands and storm water ponds for both pre - developed and post - developed conditions. Water Ouality ' The SWMP has established an assessment rate for water quality systems. The cash dedication shall be equal to the cost of land and pond volume needed for treatment of the phosphorus load leaving the site. The requirement for cash in lieu of land and pond construction shall be based upon a schedule in accordance with the prescribed land use zoning. Values are calculated using the market values of land in the City of Chanhassen plus a value of $2.50 per cubic yard for excavation of the pond. This fee is not applicable since the applicant will be assessed for the Brenden Pond August 17, 1994 Page 6 Lake Lucy Road storm drainage improvements. The appropriate drainage and utility easements should be dedicated on the final plat. Water Quantity The SWMP has established an assessment rate for different land uses based on an average, city- wide rate for the installation of water quantity systems. This cost includes all proposed SWMP trunk systems, culverts, and open channels and stormwater ponding areas for temporary runoff storage. Single - family residential developments will have an assessment rate of $1,980 per acre. The proposed development would then be responsible for a water quantity assessment fee of $35,501 assuming 17.93 acres of developable land. The City will apply credits to the applicant's surface water quantity fees for construction of improvements in accordance with the SWMP which include such items as outlet control devices, trunk storm sewer pipes, ponding, etc. An analysis of the SWMP fees and Lake Lucy Road assessments will be performed in conjunction with the final plat and construction plan and specification review process. DRAINAGE The applicant as petitioned the City to construct Lake Lucy Road. The City authorized preparation of a feasibility study for the extension of Lake Lucy Road between Trunk Highway 41 and Galpin Boulevard (County Road 117). On June 13, 1994, the City Council approved the feasibility study and authorized preparation of construction plans and specifications for Phase I of the roadway improvements. Phase I will include extending Lake Lucy Road from Trunk Highway 41 to the intersection of proposed Pondview Court. The project includes construction of streets, sidewalk, utilities and storm drainage improvements. This development is dependent upon this project in order to develop. Without these improvements the plat is premature. Therefore, preliminary and final plat approval should be contingent upon City Project No. 92 -12 being ordered and bid awarded. This development will be subject to assessment as a result of the City's improvement project. The east side of the development is located within the Lake Lucy Watershed which is under the jurisdiction of a Riley Purgatory Bluff Creek Watershed District. The west side of the development is within the Lake Minnewashta Watershed which is under the jurisdiction of the Mmnehaha Creek Watershed District. It appears the runoff from the site will drain into the ag/urban wetland. The ag/urban wetland' will then drain into the natural wetland. The natural wetland drains to the east through a series of other wetlands before it eventually discharges into Lake Lucy. Since the Minnehaha Creek Watershed and the Riley Purgatory Bluff Creek Watershed boundaries are being altered both watershed districts and the Board of Water and Soil Resources should be informed of the alterations proposed to the watershed boundaries. The storm watei runoff from the front yard areas and street will be conveyed via storm sewers into a sedimeni basin that the City's improvement project will be constructing prior to n 1 ' Brenden Pond August 17, 1994 Page 7 discharging into the ag/urban wetland. A sediment basin will be designed with the City's project to hold back sand and silt running off from the proposed development and the Lake Lucy roadway before it enters the ag/urban wetland. Staff believes that a sediment trap is sufficient water quality treatment in this situation; however, the inlet from the sediment trap to the ag/urban wetland should be located well away from the outlet that discharges the ag/urban wetland into ' the natural wetland. This will be modified on the City's construction plans. GRADING ' (Please refer to sheet 2 of 7 for the radin plan. Grades shown on sheet 6 of 7 are g g inapplicable.) ' The site contains a significant grade variety of elevation changes and vegetation. There are steep ' slopes in the northwesterly and southerly portion of the site. The proposed plans show extensive grading to develop the site for house pads and streets. A development plan should be prepared or included with the grading plan indicating the type of dwelling to be built on each lot. There ' are some very steep slopes in the northwest corner of the development that will be re- graded. Staff has met with the applicant and Mancinos in the field to determine access and utility service location. Outlot 'A' has been set aside for a private driveway to service up to four home sites on the Mancino parcel lying west of the ravine. Utility service will also be extended to the east end of Outlot A. Staff reviewed another potential location for this access road at the southwest corner of the property ( Outlot B); however, the slopes leading into the Mancino property here ' are very steep and resulting road grades would be greater than 10 percent. The extension of Outlot A appears to be the best alternative since it would eliminate steep road grades and allow some natural resource continuity between the wooded area on Mancino's property and the ravine which extends from the wooded area south to the wetland. We believe this alignment will minimize impact to the surrounding property and still provide a feasible access and utility service for the west side of the Mancino parcel. According to the City's SWMP, a water quality pond is proposed adjacent to the natural wetland ( Outlot Q. The applicant will be required to dedicate a portion of Outlot C as a drainage and ' utility easement. EROSION CONTROL ' The applicant will need to develop a sediment and erosion control plan in accordance with the City's Best Management Practice Handbook (BMPH). Type III erosion control fencing will be required around the natural wetland. The steep slopes may also require some form of terraced erosion control fencing. The plan shall be submitted to the City for review and formal approval in conjunction with final plat approval. The City has adopted a Best Management Practice Handbook which the applicant can purchase from the City at a cost of $25 to assist with the design process. Brenden Pond August 17, 199 Page 8 j UTILITIES With the construction of Lake Lucy Road, sanitary sewer and water lines will be extended to serve this development. Staff has reviewed different alternatives to provide the Mancino parcel with street acce s and utility service. Staff recommends that the applicant be required to extend utilities along with access for future extension into the Mancino parcel through Outlot A. The utility plans are relatively straightforward. Water service will be extended from Lake Lucy Road. A detailed anal Isis of the construction plans will be performed in conjunction with the final plat submittal process. Fire hydrants shall be placed a maximum of 300 feet apart. All utility construction shad be in accordance to the 'City's latest edition of the Standard Specifications and Detail Plates. Detailed construction drawings and specifications for the utilities and street improvements will be required for submittal with final plat approval. The construction plans and specifications will be subject to staff review and City Council approval. In conjunction with the final platting process, the applicant will be required to enter into a development contract with the City and provide the necessary financial security to guarantee installation of the public improvements and conditions of final plat approval. The City will also be looking to acquire land for construction of a well site on Outlot C. STREETS Access to the development is proposed from Lake Lucy Road extending from Trunk Highway 41. This segment of roadway will be built under the City's Improvement Project No. 92 -12. Lake Lucy Road is considered a collector street based on the City's Comprehensive Guide Use Plan. It is al�o part of the City's Municipal State -Aid Route. According to the City's subdivision ordinance, direct driveway access onto a collector street should be restricted or controlled whenever feasible. Due to topographic constraints, staff believe there is no other feasible access point available to these three lots. Staff is comfortable with Lots 1, 2 and 3 having driveway access onto Lake Lucy Road. Staff is also recommending that development of Outlot B, depending on the future alignment of Lake Lucy Road, may be required to utilize the interior street (Pond View Court). The extension c prepared a feasi two other parce The first parcel located northea options for acc( potential alignn parcel.

Staff has also met with the Ryans and discussed two ants for Lake Lucy Road', which impact the development potential for the Ryan no clear -cut alignment that satisfies all of the property owners in this situation. submitted a preliminary plat for review. They have utilized the northerly ce Lucy Road through their parcel. Staff has reviewed this preliminary plat and sign standpoint, Lake Lucy Road will have to be revised slightly to align with 1 1 n J -, Brenden Pond August 17, 1994 Page 9 ' this development. Staff has also reviewed the southerly alignment of Lake Lucy Road through the Ryan parcel which leaves the westerly portion of the site very difficult to develop due to very ' steep slopes. The resulting impact requires short, steep cul -de -sacs as well as tuck -under type homes versus walkouts overlooking the wetlands, or delay development of the westerly 1/3 of ' the Ryan parcel until the Mancino parcel develops in an effort to maintain the natural terrain. Access to the Mancino parcel through this development has been resolved. Since the applicant is not platting Outlot B, this gives sufficient room for modifying Lake Lucy Road alignment to ' match with the Ryan parcel. Staff still supports the southerly alignment of Lake Lucy Road. The applicant is proposing to dedicate an 80 -foot wide right -of -way for the construction of Lake Lucy Road through the development. The plans also propose a 60 -foot wide right -of -way and construction of the City's standard roadway section for Pond View Court. This typical section will allow for sufficient room for a sidewalk if so desired to access Lake Lucy Road to the ' school immediately north of the development. Street grades range from 0.5% to 10% which is over the City's maximum grade allowed. Staff believes this grade is warranted in an effort to minimize grading and tree loss on the site. Staff is in support of granting a variance to the 10% ' street grade. Detailed construction plans and specifications for the street improvements will be required as part of the final plat submittal. Access to the Mancino parcel will be through Outlot A via a private street. Staff was directed by the Planning Commission to evaluate the environmental resources on the site and the adjacent parcel to the east (the Mancino property) before making a recommendation ' on the access issue. The westerly portion of the Mancino property is densely wooded with mature trees and contain a ravine. Building a street up to city standards through the Mancino property would not be feasible as it will remove a substantial number of trees. The only solution ' to preserving the trees and allowing some development on the site is to access it via a private street. Current city ordinances allow a maximum number of 4 homes to be served via a private street. Staff has brought this issue to the attention of the Mancinos and they have indicated that ' they do not intend to have more than 4 homes on that portion of their property. PARK DEDICATION The Recreation Section of the iv identifies n h r Com pees e Plan de tifies this site as lying within the park service area of Herman Field Park and the Minnetonka Intermediate School campus. A trail is identified on the comprehensive trail plan, running east/west along the extension of Lake Lucy Road and will be constructed as a part of this future road project. The Park and Recreation Commission reviewed this application on August 9, 1994, and recommended the Planning Commission require a 5 foot wide concrete sidewalk on one side of Pondview Court extending north to the school property be incorporated into the construction I Brenden Pond August 17, 1994 Page 10 plans for Brend�n Pond. The applicant is to construct this sidewalk and convey any and all easements requiied by its alignment to the city. The Park and Recreation Commission also recommended full park and trail fees be collected per city ordinance in i lieu of land acquisition and/or trail construction.

The ' grading plan has 71,667 a large number Pondview Lour' 56,526 I TREE PRESERVATION/LANDSCAPING , The applicant as submitted a Preliminary Tree Inventory Plan. The site contains significant concentrations of mature trees along the iwest edge of Lots 7, 8, 9, 10, 11, and 12, and easterly portion of Lots and 2 of Block 2. Grading will only take place over portions of Lots 1 and 2, , Block 2, with the exception of a 30 foot wide conservation easement located at the edge of the site leaving those trees intact. Grading will also affect a portion of the trees located on Lot 12, Block 1. The applicant will be required to replace these trees as required by ordinance. The ' grading plan has been revised to eliminate any clear cutting of trees on Outlot B. Unfortunately, a large number Hof trees will be lost due to the extension of Lake Lucy Road. ' All of the ve e g ted areas that are being saved shall be reserved b a conservation easement. � g P Y The Landscaping and Tree Preservation requirements state that a landscape buffer is required when a subdivi, ion plat is contiguous with a collector street. Required buffering shall consist of , berms and landscape materials consisting of a mix of trees and shrubs and /or a tree preservation area. The plan must identify plant material locations along Lake Lucy Road as well as planting within each front yard. Appropriate financial security will be required. This plan should show ' the type and size of trees proposed to be planted as well as the location of berms along Lake Lucy Road. A reforestation plan will attempt to replace all those trees being lost due to grading and road extension. The city can require caliper replacement of trees. Staff is recommending that the ' applicant work with staff to develop a reforestation plan to replace the tree removal. Staff believes that th� Lake Lucy Road project will most likely include a streetscape plan similar to , Minnewashta Porkway. The following constitutes our calculation of the required forestation and tree replacement: There is a 16 %baseline canopy coverage (3.2 acre). Tree canopy within a designated wetland is excluded fro calculation. The required post development canopy coverage is 25 % or a total of 5 acres of try canopy. To meet the minimum canopy coverage requirements, the developer would need to develop a forestation plan !for 1.8 acres (5.0 -3.2) which would require the planting of 72 trees. (1.8 x 40). In addition, because the developer is removing canopy coverage that is ' required to meet their minimum canopy coverage, they must replace the removed canopy area at a rate of 1.2 tirr s the canopy coverage area being removed. Since the applicant did not provide these calculations, staff has estimated that the removed canopy coverage area is approximately , 107,500 square feet. The replacement planting is then calculated at 129,000 square feet (107,500 x 1.2). The i umber of trees required for replacement planting is calculated at 119 trees Brenden Pond August 17, 1994 Page 13 (129,000/1089). The total tree planting requirement as part of the development for forestation and tree replacement is 191 trees. PLANNING COMMISSION UPDATE ' On August 17, 1994, the Planning Commission reviewed and tabled this application and directed staff to address the following issues: ' * A tree inventory and landscaping plan be submitted to the city for review and approval. * Evaluation of the environmental resources on the site and the adjacent parcel to the east. * Resolve the access issue to the Mancino's property and investigate if there is a feasible way of providing a street to serve their property. The applicants (David Gestach & Lee Paulson) and their engineer (Alan Larson, Engelhardt & Associates), owners of the property located east of the site (Sam and Nancy Mancino) and their surveyor (Ted Kemna), and Engineering and Planning staff met on August 26, 1994. After walking the site and evaluating access option, all parties reached concurrence on the issue raised ' by the Planning Commission. On September 7, 1994, the Planning Commission reviewed this item for the second time. At that ' meeting, the owner of the neighboring property located northwest of the subject site, Mr. Dennis Clark, stated that there is a large number of mature trees located on Lot 12, Block 1, that have not been shown on the plans. These trees will be lost as a result of the grading. Mr. Clark requested year round buffering between his property and the proposed subdivision. The applicant has submitted revised plans showing the wooded area on Lot 12. A large number of these trees will be removed as a result of grading, however, they will be replaced as required in the reforestation ordinance. Mr. Clark also had concerns over increased drainage into his property. The Planning Commission added a condition requiring the applicant and staff evaluate potential concerns as it relates to potential run on for the adjacent property owner from Lots 10 -13, Block 1. The Assistant City Engineer evaluated the drainage with the applicants engineer. Due to site grading, the front yards of the homes will be draining onto Pondview which will result in less drainage onto Mr. Clark's property than there currently is today. Upon completion of the site grading, staff will further ' evaluate if a drainage swale would be necessary. Staff felt that this can be easily modified in the field. I The Planning Commission approved this application unanimously with the conditions outlined in the staff report. Brenden Pond August 17, 199 Page 14 ' Staff recommends the City Council adopt the following motion: , REZONING I "The City Council approves of Rezoning #94 -5 for property zoned RR to RSF for Brenden Pond as shown on the plans dated August 30, 1994 and subject to the following conditions: , 1. The app 'cant shall enter into a development contract containing all of the conditions of approval for this project and shall submit all required financial guarantees. The ' developr�ent contract shall be recorded against the property. 2. The applicant shall meet all conditions of the Subdivision #94 -10." , "The City Council approves the preliminary plat for Subdivision #94 -10 for Brenden Pond for 19 single family lots and 4 outlots with a variance to the street grade (10 %) on Pondview Court as shown on the plans received August 30, 1994, subject to the following conditions: ' 1. All ar 4 disturbed during site grading shall be immediately restored with seed and disc - mulched or wood fiber blanket within two weeks of completing site grading unless the , city's (> MPH) planting dates dictate otherwise.

Planning TED IN Public Meeting - September 7, 1994 Lee Paulson St. Bonifacius Dennis Clark 6651 Hazeltine Blvd. David Stockdal, 7210 Galpin Blvd. David Gestach Brian Klingelh tz Sam Mancino 6620 Galpin Blvd. Peter Davis 6640 Galpin Blvd. Sharmin Al -Ja presented the staff report on this item. Scott: Any questions or comments? Conrad: May I have one of Dave. I've got to talk about Lake Lucy. It's deemed a collector street. Did we do a traffic count? When it was reviewed, do we know what it has to, what the future traffic's going to be on it Dave? Hempel: A few years back there was a Eastern Carver County Transportation Study predicting the 4affic flows and counts eventually throughout the city providing east/west connections. North/south streets and designating... arterial kind of collector street. This area has been designated as a collector type of road. I don't know off the top of my head what the traffic projections are. Conrad: There s no traffic to the west that is really going to search this out. I can't, there's just no traffic that's going to seek this road out so it really is servicing only this area that we are now lookin for development. The Carlson's may be another development but really this is a roadway that's just going to serve the neighborhood basically. Hempel: Well it does provide for the east/west continuity between Galpin to Powers Blvd versus going all the way up to Highway,' 7 or going to Chaska Road. This is actually a vital 24 Planning Commission Meeting - September 7, 1994 connection, east/west connection. Another east/west connection through is being provided to the south through the Carlson/Song/Lundgren development where it was part of the... approximately 2 miles south of this location. Conrad: Okay, it's an east/west connection. So when you say that to me does that mean you're saying it's serving more than the neighborhoods? With that 40 houses, this street will service 100 houses in this developing valley. Hempel: That's correct. And additional city wide traffic. Conrad: Going where? Hempel: Going to another connection from the northwest art of town to et to the P g P g downtown versus going down Trunk Highway 41 and Galpin to Trunk Highway 5. It's not imaking any shortcut I wouldn't think but it does provide a viable east/west travel route. 1 Conrad: Have we made any compromises by terming this a collector? Have we, are we forcing a major road in when a major road is not necessary? Hempel: The roadway section that we're proposing to build here is not much larger than the standard street right -of -way. Our standard street for a residential neighborhood is 31 feet wide. This street is proposed to be built at 32 feet wide. There is additional right -of -way though that's being required with this to provide when the trail/sidewalk, the 8 foot wide trail/sidewalk will give us larger boulevard areas for planting... Conrad: Okay. That's all. Scott: Any other comments? If the applicant would like to make a presentation, please do ' so. It's not a requirement. If you'd like to, please go ahead. Dave Gestach: Dave Gestach, 8001 Acorn Lane, Chanhassen. I guess basically we just ... and we hope that you do approve it so we can go to Council. Scott: Good, thank you. This is a public hearing. Just a show of hands. How many people are here to speak at the public hearing for this particular project. Okay. Can I have a motion to open the public hearing please. Ledvina moved, Conrad seconded to open the public hearing. All voted in favor and the motion carried. The public hearing was opened. 25 I Planning Commission Meeting - September 7, 1994 '+ �J Dennis Clark: My name is Dennis Clark. I live at 6651 Hazeltine Boulevard. I was wondering, Sharmin could we use that overhead again and possibly enlarge that. Enlarge it a little bit. Al -Jaff: I don' think we can do that. ' Dennis Clark: Okay. Actually I'm kind of Johnny come lately on this project. For some reason I was not served notice on this development. I received my first notice last Friday. , I've been out of town since Friday. Came back in town Sunday. Had Tuesday to even prepare for this! Staff has been giving me a crash course on this and I definitely have some concerns just because probably I have gone over staff notes and gone through everything but I kind of made a wish list here of what are some of the concerns I have. I think I'm just going to mark on there where my house fillies on the 8 acres that I have. Scott: Yeah, that would help. None of us see our home from that vantage point very often SO. Dennis Clark: You only see my house in the winter time. I've been pretty much aware that this has been tabled before or presented before but frankly I was a little shocked that this was going through this bit of preparation fast. From August 17th up until today so obviously there's been quite a by staff on this and maybe this thing is a done deal. But I guess a couple of the specific Issues that I have which concern my lot are the northwest development of the property that we're I talking about which seems to be somewhat ignored in the notes that I've , little to the northwest lots in to the trees. I had an seen. see very) addressing regards in here. I'm hearing opportunity to talk with a few people and what type of homes are going anywhere from 2 $250,000.00 to $500,006.00 homes. I question, I'm not a realtor but I have , been here for 1/2 years. I was in the market. I question who's going to spend that kind of money on Lot 13 an d 14 next to probably a 100 feet from a Minnetonka basketball court. So there's some issues that I'm questioning; plus the fact that according to the way the plat is here and the way the foliage is or the way the excavating is, it can't be done without taking a lot more trees that don't even show up on this plat. A lot more trees. Very mature trees and I'm specifically talking about Lot 12. I'm concerned about Lot 11, which if you look at the contour line of Lot 11, and maybe you've never had a chance to be back there. Lot 11, where the house is, is a gravel pit. It's probably 20 to 30 foot drop so when I look at the notes and see where you're talking about significant grading, I think that's a pretty lame word. We're talking about very significant grading and I guess I don't understand how it's going to lay in the contour of the land the way it is unless that's being filled or I don't know. I haven't had enough time to get these questions answered. The tree inventory. I think that even as of today, I don't know what the tree inventory is. I don't have the updated notes, if there is some. I don't know if it's been presented but I think there's considerable more trees 26 1 Planning Commission Meeting - September 7, 1994 than what are shown on the map and I guess from where my standpoint is, the front and back of my house. Now when I come to my driveway, from what I understand, I'm going to be looking at, there's quite a bit of elevation. I'm going to be looking at the backs, or the backyards of 3 homes. These people will be kind of hovering over me. So be it but am I also going to be looking at 3 Menards pole sheds coming into my yard? Is it going to look like Milacs Lake or what, I don't know. I'm very concerned about that. I think for the acreage that I have, just specifically in getting to some of the points, I'm going to be looking for some concessions and some buffer trees and I think this should be definitely an issue before we continue with this. Not well we'll take care of you. I want to know that I'm looking for some year round buffer trees that are bordering my property if this is a done deal. I think I deserve that and I'm thinking evergreen type trees, 10 to 12 feet tall. This is going to give me some of the privacy that I deserve with that size of a lot. This will devaluate my lot if this does happen. I cannot develop this lot that I have. This acreage is, it's a done deal. You can see it's kind of laid out a little goofy there and it is a nice lot. I've kind of been in this movie before. I just came from probably one of Shorewood's most embarrassing developments. I lived adjacent to one that took 7 years, 4 townhomes. Christmas Lake Woods. And there was a lot of promises on trees and trees that weren't going to be removed and in the final, it didn't happen. And the saws were going until 10:00 at night, on Saturdays and Sundays and the townhomes were $170,000.00. Way over priced 10 years when they ' started the thing. The market fell 14% and the project sat. So again I'm not a financial wizard on this stuff but I question, to me this looks like a trailer park layout and from Highway 41, the way these homes are going to get stacked across here, again I need to know a little bit more about the project. Maybe I'm coming in here late and I don't even know what my legal rights are as far as getting my notices and what have you. I would recommend to the city that these things be sent certified. Jerome Carlson, who just recently purchased this plat over here, his name is on the plat but the person I purchased the plat from 2 1/2 years ago, still his name is on this plat. So I don't know where things are slipping through the cracks there. The trees in question on the south side, in Lots 1. Or I'm sorry, 13, 12, 11 again was a gravel pit. I'm talking about probably 100 trees that are fairly mature. Anywhere from 12 to 30 feet tall. Evergreens again. In other words, they hold quite a bit of cover. I've done some measuring today. Took the day off and went out and measured this 1 stuff. Working with the contours and that. A lot of trees got to be taken out. The next thing that I'd like to point out is, there's already quite a bit of forestation on this property this summer. This thing was clear cut in a day. The whole 25 acres of popals that have grown up over the years. So you can see right away where I have some question about, I don't know if I'm going to use the word trust but I think we would have been further off and maybe what we had here for foliage. These were anywhere from 7 to 12 foot, even taller popal trees. Maybe they're worthless, I don't know but didn't like it. Just put it that way. There's been no communication from the developers on this project. I think that's rude when they're going to go in and if you can't even talk to the people that you're getting up against. 27 n j Planning Commission Meeting - September 7, 1994 Maybe from a developer's standpoint, don't talk to the neighbors. I don't know. Just my opinion. I'm kind of on a lowland. I rn' below this, you can see all this drainage here where it does go back out on the lake again but I'm kind of what I would consider a lowland. When you start taking this square footage on house roofs here, right next to my property line is my drywalls stem. I had an opinion done on that today. When you've got water coming down these hills and you've got natural vegetation, I've got a sump pump in my house that runs continuously when it rains. You know what's going on there. I've always wondered how my drywal} was doing. Now I'm even going to have more concerns about the drywell when you start taking this type of square footage and even sending that much more water down, particularly on my lot. A couple other questions that I've got is, I'm trying to get the Minnetonka Sc�}� ool system to quite using fertilizer on their lawns up there. They've got the most beautiful lawns in the world. No dandelions, nothing. All that water comes right down that drainage di ch into that pond. That pond is getting worse and worse every year and I think we've got, we're making some headway there and this pond is turning in to be a green t slime ball. It does hold fish. I do feed it minnows. I spend about $300.00 a year throwing spawn... minnows in there for crappies and what have you. And when I look at this buffer around the lake this 10 foot buffer. I mean I don't know what the regulations are and where we're headed oI � this stuff but this pond'Is going to be ruined. Just plain and simple. When you start puttin� lawns in there, you've got a problem. 10 foot buffer means nothing. We've got problems coming from Minnetonka so again this is just another point that I have concerns about. I don't know if it's been addressed or what the situation is. Is there going to be docks on this pond? How is this pond going to be preserved? Can ... put a dock on this thing? Can he fish off it? What's this going to I look like from the road? You actually do have a public access from the road. You can fish from shore. From the highway side so I don't know what this is going to bring. This feeder road. My kids get on the school bus on this road and we've had near accidents with a stopping red flashing light. When cars come over that hill going north, trucks, 70 mph easy. 80 coming over. When this road goes in here, you're going to have some problems. I'll go on record on that. You're going to have ' problems with that road. The road's in, that's great but unless there's going to be some lights there, people coming in and out of there, there's going to be accidents there. Just they can't help it. It's a blind spot. So when you're coming over that road and ... 70 mph is not even, , they go faster than that coming over. I would like to see that whole thing, with the park in there and with the school. When you get down by Chaska and that school system and that's all 40 mph. This is still 55. And so I think you should look at slowing that traffic down on TH 41. I don' know what powers you've got in that. So I guess my main concern is, getting back to my own personal problem, is I am definitely looking for something that is going to assist my view of what once was fairly ... woods and nice woods and a meadow to buffer that all and I'll leave it at that for now. And I again, like I said, I'm kind of looking to see an updat� would say you're on this tree survey because this isn't close. It's not even close. And I more than welcome to walk some of the ... lot. It's not on there so I've got 28 I II ' Planning Commission Meeting - September 7, 1994 a problem with staff saying we're r eady to approve. A ll you've got to do is work a few things out. I'm not ready and I've had 24 hours to do it. Basically a bad night's sleep also because I think this is going pretty fast. Maybe someone has some other comments. Thanks. ' Scott: Good, thank you. Just a couple of comments. One question I think since we're talking about preservation... I think it's entirely appropriate to consider a 30 foot preservation area along the westerly sides of Lots 11, 12 and 13. If there's significant vegetation there, ' there's no reason why that can't be continued around. Dave, drainage. My understanding is that the drainage from this development will be conveyed down a storm sewer running down whatever street that is into the holding ponds down below so conceivably there could be some drainage going off the back but that'd be through lawns or something like that so you don't have a concern about Mr. Clark's property as to drainage. Okay. And 10 foot buffer around the pond, that seems not to be in keeping with our wetland plan. Is it actually 10 feet? Is it more than that? Or is it because of the nature of the wetland. Aanenson: No, it's the buffer setback into the wetland. Building setback. What you're ' talking about is ... minimum landscaping. Scott: Yeah. So from the actual property we could be looking at 60 -70 feet. 50 feet. Okay. And then speed limits on state highways. The State, that says it all I guess. State of Minnesota. Okay. Thank you for your comments. Any other comments on this particular issue? Yes sir. ' Peter Davis: Yes, I'm Peter Davis. I live at 6640 Galpin Boulevard. Part of the, this Brendon Pond development includes a recommendation of some park dedication land that would tie the street to provide an access into the Minnetonka school. I was hoping to get more recognition made to the fact that when the Lake Lucy extension goes in, that this is going to be a fairly active path and I was hoping to see more recognition to the trail system as part of the outlots that would be placed on the north side which would provide for a very natural path for a lot of people extending east all the way to the other trail systems because you can go out through the top of the school where there's already an extension into other parts further north of Chanhassen. I was hoping to see more language in the recommendation that would provide from where that road alignment of the trail system... pedestrian standpoint, ' make more of a route. Aanenson: I'm sorry, I'm not following you. Peter Davis: Right now what's going to happen is there's only language that talks about an access point up in here to the school. In terms of when Lake Lucy gets developed in this direction to the Ryan property, I was hoping to see more language built that would pull the 1 29 I. Planning Commission Meeting - September 7, 1994 trail system to the north so you'll have more of a natural... Aanenson: That s the plan. That's the plan for Lake Lucy that there's a trail system along the northern side. That's what the Ryan's engineer was saying, they would prefer to have it on the south side but it was always planned to have it on the north side because that's ' where... Peter Davis: 0 cay, I didn't see that. ' Aanenson: Th is where we believe most of the traffic will be going. To get up to the junior high. Peter Davis: Right. Okay. Hempel: There's also a sidewalk being proposed along the west side of the street to connect from the trail horn Lake Lucy Road north. Peter Davis: at was my question. It really wasn't clear how that was going to tie back in. Thank you. Scott: Good , th� ank Y ou. An other comments? Y Sam Mancino: Yes, Sam Mancino, 6620 Galpin Boulevard. Over the course of the last few , months we have been pleased to be able , to work out most of the issues between ourselves and Gestach - Paulson people with the help of staff on this and I think that we've got the right contingencies fpr future potential development if we ever chose to do that. The one issue that I'd like to raise here, you are considering platting, as it is properly laid out here. There's a portion called Outlot B which will be considered at a later date. The reason for Outlot B is to allow future alignment pending determination of the way that Lake Lucy Road extends to the east, which is the Ryan property. If in the course of that decision the road takes the northerly route, what will probably happen is that it will have to cross that finger of wetland and trees whic can do a fair amount of damage there. The question before us I guess is, would that lot by itself allow enough room for mitigating the damage done there or would ' that have to be taken into account now. A question. ' Aanenson: Are you talking about wetland mitigation? Sam Mancino: Yes. Because you will be going through, if the road takes the northerly alignment, would it require some wetland mitigation that this lot would not be large enough to accommoda le or wouldn't be appropriate to accommodate here? And does that then argue 30 1 IPlanning Commission Meeting - September 7, 1994 for the southerly alignment of that road to avoid that problem? Hempel: I guess first of all it'd have to be classified as a wetland. From our guidelines from our Water Resource Coordinator, the wetland ... would have to review the site to determine if it qualifies for a wetland status. It would be, if we're impacting it with ... assume that we would have to mitigate for our impact. Sam Mancino: I guess this was an issue that if the road takes a southerly alignment, it's probably a minimal concern. Aanenson: ...it would have to meet the Wetland Conservation Act but that doesn't mean it has to be done ... I think your point's well taken and that goes back to our—trying to preserve wetlands on the site. Sam Mancino: Thank you. Scott: Good, thank you. Would anybody else like to make a comment? Sir. Brian Klingelhutz: My name is Brian Klingelhutz and I was involved with Dave and Lee. We bought the property about 10 years ago. We've been working on developing it since then. You know off and on. Not constantly but when we bought the property it was all, Mr. Brendon made his living off of farming all that land so it was just all fields and there were trees around the borders but where they have the 30 foot section there protecting those trees, 1 that is protecting all the trees that are mature. So there is a lot more trees there but there's just little scrub trees that you can't even walk through so. I want to point out that we've worked with Mr. Carlson. We've worked with Mancino's. Maybe we didn't address Mr. Clark enough. He wanted to buy some property from us. We never made that deal. I don't know if he's upset about that or you know, but you can't please everybody you know. I pulled in his driveway this afternoon to talk to him. I was in his driveway looking over ' towards our property. The property that's going to be developed and you couldn't even see that property from his house. You know there's so many trees between his house and the property right now so, I mean it wouldn't do any good to plant any more trees there because you'd wipe out some of the trees that are really there. So I'm just saying that we've done everything we could. I hope you, you know we have nothing against Ryan's development but we've been working on our's for a couple years and so I just don't want you to tie our two together. We've put a lot of planning into our's. Just because you tabled their's, because we're right next to each other but we've been working. As you can see that it's 25 acres and ' we only have 19 lots in there which ... so I just hope you pass it. Scott: Good, thank you. Would anybody else like to speak at the public hearing? Seeing 31 Planning Commission Meeting - September 7, 1994 none, can I hav a motion to close the public hearing please? Nutting moved Ledvina seconded to close the public hearing. All voted in favor and the motion carried The public hearing was closed. Scott: Ron. Nutting: Well I guess I was pleased to see that the property owners and the Mancino's and staff were able io address the issue of the outlot and the private drive and to get that resolved. I'm not tying this project together with the Ryan project. They are connected by the Lake Lucy Road but I think what we, the consensus from staff and the people up here is that the southerly alignment made more sense and that's the alignment that we're talking about with this plan. ShoA of some new concerns or issues that were raised tonight, I think I am in a position to go f rward but I guess I have a little bit of confusion on the tree inventory and exactly what's ere. We've taken great'; pains to address that issue on the easterly side bordering the ancino's property. I don't know if staff has any input to this but I'd like to just understand a little bit more about the impact that we're going to have on the property owner to the west because we've been careful in this development to address the needs of everybody and I just need to, I'm not saying I'm not ready to go forward with it but I just don't know enough. Al -Jaff: We ca work with the applicant to make sure that all the trees that are on the site right now be reflected on a tree survey and then we will ... would have to be replaced according to our ordinance at a rate of 1.2. But I think that this is an issue that we can work out. Nutting: Okay) That you, with the developer and the property owner to the west, okay. Okay. I have no further comments. Scott: Matt. Ledvina: In re accuracy in tern Sharmin Al -Jaf Ledvina: Base site to look at i Al -Jaff: There 3 to the tree inventory. Is that accurate and I guess what is the level of of the size of tree and have you reviewed that? s answer was not picked up on the tape. on the comments that have been made here, you said you've been out to the it? Okay. were some trees, spruces; located to the west of the site that are not shown on 32 I. 0 1 l ti Planning Commission Meeting - September 7, 1994 this and we will ... that they be shown between now and the Council meeting. Any trees that will be removed would have to be replaced at... Ledvina: Are those spruce trees within the grading limits, do you believe or are they outside? Al -Jaff: Some of them are. Two of them are within the grading limits because... Ledvina: Okay. The adjacent homeowner had a comment about pole sheds or whatever and I just would want him to know that of course the city has ordinances as it relates to a construction of buildings and out buildings are, you know have to be done by permit and size limitations, etc so, and in a residential, high quality residential neighborhood you will not see that scenario, I don't believe. I think the request for additional buffer trees, if they're necessary, would seem to make sense. Have you had an opportunity to assess that need at this time? Al -Jaff: There's going to be over 100 trees that will need to be planted on the subdivision. g g P So I'm sure that there will be some trees that we could add there if there is need for it. Ledvina: Okay. Maybe we could add a recommendation to that effect directing the applicant to intensify year round plantings in that area. I think that might be appropriate. I don't want to be real specific but again, I want to make sure that that screening does occur if needed. And just a follow up on drainage. Again, the adjacent homeowner is correct. There will be increase impervious area there, and it seems to me that if I look at the plat and the topography for Lots 10 -13, Block 1, it would appear that a drainage swale along the back of those lots would be very easily done. You know within the grading limits there and provide or prevent I should say run on onto his parcel and potential problems that may occur. Dave, did you have any thoughts on that? Do you think that's a reasonable thing or do you see any concerns with that? Hempel: I actually believe that the amount of runoff going to the west of this development will actually be lower than the natural conditions that are out there today. The front yard area, the front half of the house will be directed towards the street which will be conveyed then through storm sewers to a sediment basin. It will only be the back yard grass areas essentially that will continue to drain to the west. The westerly edge of the cul -de -sac appears to be about the high point of the natural terrain out there right now. It's probably actually reducing the amount of runoff running west. 1 Ledvina: Okay. Even with the construction of the houses in that area? Hempel: That's correct. 33 - P Planning Comnussion I Meeting - September 7, 1994 ' Ledvina: Okay Well maybe perhaps we can direct the applicant to evaluate that condition to make sure that -we're not causing a run on type of situation to the neighboring property. I i wouldn't want �o see that occur. The issue as it relates to buffer around the wetland area or the pond area. INow how do we classify' this pond? Is this like an ag urban? Al -Jaff: It is an ag urban...buffer that wraps around the wetland. Ledvina: Okay. Is that by definition or is there some leeway in establishing that buffer zone? Aanenson: They're at 20. The average.,. Ledvina: Okay, but it can range 0 to 20, is that what you're saying? Okay. Would there be any down side in increasing that buffer area to 20 feet in that area? It appears to me that that's a conservation, much of that area is a conservation zone. Scott: Tree preservation. Ledvina: Or tree preservation and also there doesn't appear to be grading in that area so it appears that that buffer strip could be increased to 20 feet Aanenson: ...in the conservation easement, you can't... Ledvina: Well from what I, you know there is the entire area here and I don't know if that conservation, tree conservation easement encompasses the entire shore area of that pond so. Aanenson: Th is what we would look to evaluate ... go back and evaluate that.. , Ledvina: Is it need little more reasonable at this time to recommend 20 foot buffer or are you saying you time to evaluate that ?' a Hempel: The only areas that I see a concern with that would be on Lots, for instance Lots 1, 5 and 6 where the grading essentially was within 10 feet of a... Ledvina: Right. Yeah, I can see that. ; I Hempel: Potentially that area would be left to grow natural after the grade is in. Aanenson: And we establish vegetation. Ledvina: I guess I don't want to see any, and I agree with the homeowner here, is people 1 34 1 Planning Commission Meeting - September 7, 1994 mowing all the way to within 10 feet of the wetland area and if we can bump that back, that would seem to make sense. Aanenson: I think you can make... conservation easement from the wetland buffer. I think if you ... just add on as far as screening... the trees closer to the home so I think we'd like maybe ' some time to evaluate that more closely and get your concerns. Ledvina: Okay. Alright. Overall I feel that the developer has been fairly responsive to our ' comments and believe that the adjustments that have been made have benefitted the plat. I think with a few more conditions, I think the concerns of the neighboring homeowners can be addressed and it can be a good situation for both the developer and adjacent lot owners I 1 should say. One question I did have and I forgot to bring this up. For Outlot B, is there a conservation easement along the north boundary of that lot? Al -Jaff: At this point we did not... Ledvina: Okay. Do we want to do anything there at this time or do we have to see this lot back again if it's developed so we don't necessarily need that at this time? Aanenson: I think you'd like to wait and see how Lake Lucy aligns. Ledvina: Okay. That seems reasonable to me. That's the extent of my comments. Scott: Thank you, Ladd. Conrad: I have nothing new to add. I agree with most of Matt's comments. Scott: Okay. Can I have a motion please? Ledvina: We've got two things here. We've got a rezoning. Okay, start with the rezoning. I move that the Planning Commission recommend approval of Rezoning #94 -5 for property zoned RR to RSF for Brendon Pond as shown on the plans dated August 30, 1994. Do we need to modify that? No, that's it. August 30th, 1994 subject to the following conditions as outlined in the staff report. Conrad: I second. ' Scott: It's been moved and seconded. Is there any discussion? Ledvina moved, Conrad seconded that the Planning Commission recommend approval 35 Planning Commission Meeting - September 7, 1994 of Rezoning #9 5 for property zoned RR to RSF for Brendon Pond as shown on the plans dated August 30, 1994, and subject to the following conditions: 1. The applic t shall enter into a development contract containing all of the conditions of approval for this project and shall submit all required financial guarantees. The development contract shall be recorded against the property. 2. The applicaij t shall meet all conditions of the Subdivision #94 -10. All voted in favor and the motion carried. Scott: Can I have another motion please. Ledvina: I would move that the Planning Commission recommend approval of Preliminary Plat for Subdivision #94 -10 for Brendon,Pond for 19 single family lots and 4 outlots with a variance to the ;treet grade of 10% on Pondview Court as shown on the plans received August 30, 1994, subject to the conditions in the staff report with the following modifications and additions. Number 2 to add, this plan shall include a list of trees and their size. The plan shall be submitted prior to final plat approval. Does that get what we need there? Okay. And tha relates to the tree replacement and reforestation plan. I guess with that I would also like to add that the applicant:; shall review the need for screening along Lots 10 -12, Block 1 as it relates to the existing single family home to the west. Conrad: Can you change that to have staff review that? Versus the applicant. Scott: Also perhaps in addition to the extend the tree preservation area which would take into consideration 19, 11 and 12 to preserve... I don't want to make it too ... If we see that there's something ther that we need to preserve and then we might not have to spend a lot of time on it. Ledvina: Yes. I I would, that condition I would have staff review the need for that screening. Aanenson: Ledvina: Yes. wetland alterati relates to the of encroached in t staff evaluate p owner from Lo the wetland. Yes. Let's see. Condition number, add to condition number 18. That any on be mitigated according to city ordinance and state laws. And that as it ientation of Lake Lucy Road, however that ends up, and if there are wetlands hat area. Adding condition 25. That the applicant evaluate, applicant and Dtential concerns as it relates to potential run on for the adjacent property :s 10 -13, Block 1. I guess that's essentially it. 7 36 1 li ' Planning Commission Meeting - September 7, 1994 IScott: Good. Is there a second? INutting: Second.

RE: BRENDEN POND (GESTACH & PAULSON), UNNAMED WETLAND 10 -132W, CITY QF CHANHASSEN, CARVER COUNTY (CITY 1.94 -10 SUB & 94 -5 REZ) Dear Ms. All -Jaff: We have reviewed the site plans dated July, 1994 (received July 22, 1994) for he above- referenced proposal (SW1 /4, Section 3, T116N- R23W) and �ave the following comments to offer: 1. Public water wetland 10 -132W, is on the proposed site. Any activity below the ordinary high water (OHW) elevation, which alters the course, current or cross - section of protected waters or wetlands, is':under the jurisdiction of DNR and may require a DNR protected waters permit. No official OHW has been established for wetland 10 -132W. Please contact this office if there is any question about whether proposed activities will be within protected water wetland 10 -132W and we ca make arrangements to estimate or officially determine, if necessary, the OHW. 2. The city of Chanhassen's Surface Water Management Plan shows an outlet for wetland 10 -132W (city basin LM -P1.3) that would go un er Highway 41. Please note that a DNR Protected Waters permit would be required for the outlet (and the city or water�hed district should be the applicant). 3. Also Purga the Z insta invol Resou It i dire trea f eat zote that this basin is currently part of the Riley - :ory -Bluff Creek Watershed District, but would drain into innehaha Creek Watershed if the proposed outlet is .led. Therefore, a change in official watershed district Lries may be necessary. The city should consult with the red watershed districts and the Board of Water and Soil -ces on this matter. pears that the stormwater is proposed to be routed :ly to wetland 10 -132W. Stormwater sedimentation/ tent ponds, or other appropriate stormwater treatment -es, should be included in the plan. I understand that t 0 AN EQUAL OPPORTUNITY EMPLOYER I .1 Ms. Al -Jaff August 8, 1994 Page 2 the city has classified this basin as an urban basin and is considering requirement of primary /sediment treatment versus nutrient treatment. If only sediment treatment is required, ' a pond /basin should still be used rather than sump catch basins (or other similar facilities), which are ineffective unless they receive a high level of maintenance. ' 4. There should be some type of dedicated easement, covenant or deed restriction for the properties adjacent to the wetland areas. This would help to ensure that property owners are ' aware that the DNR, the U.S. Army Corps of Engineers, the City of Chanhassen, the Riley- Purgatory -Bluff Creek Watershed (or the Minnehaha Creek Watershed) have jurisdiction over the areas and that the wetlands cannot be altered without appropriate permits. 5. DNR public water wetland unnamed 10 -132W should be labelled as ' such in future plans or plats and the OHW, if available, should be noted. ' 6. There may be wetlands on the site that are not under DNR jurisdiction. The U.S. Army Corps of Engineers should be consulted regarding pertinent federal regulations for activities in wetlands. In addition, impacts to these ' wetlands should be evaluated by the city in accordance with the Minnesota Wetlands Conservation Act of 1991. I 7. The following comments are general and apply to all proposed developments: 1 a. Appropriate erosion control measures should be taken during the construction period. The Minnesota Construction Site Erosion and Sediment Control Planning Handbook (Board of Water & Soil Resources and Association of Metropolitan and Soil and Water Conservation Districts) guidelines, or their equivalent, should be followed. b. If construction involves dewatering in excess of 10,000 gallons per day or 1 million gallons per year, a DNR appropriations permit is needed. You are advised that it typically takes approximately 60 days to process the permit application. C. Construction activities which disturb five acres of land, or more, are required to apply for a stormwater permit from the Minnesota Pollution Control Agency (Scott Thompson @ 612/296- 7203). Ms. Al -Jaff August 8, 1994 Page 3 d. The comments in this letter address DNR - Division of waters jurisdictional matters and concerns. These comments should not be construed as DNR support or lack �hereof for a particular project. Please con act me at 772 -7910 should you have questions.

About half of the wetland extends off -site to the west; approximately 5.17 acres of wetland is on si e. This wetland is DNR protected water, 10 -132W. An ordinary high water mark has not been established for this wetland. Southeast Basin s a large natural wetland located in the southeaster comer of the property. The majority of the wetland is off- -site with only approximately 2.03 acres 1, on =site It, does not appear that the wetland will be impacted as a result of construction of Lake Lucy Road, however, it is very important 'hat type III erosion control be constructed around the wetland and well maintained during construction. There will be:"_ me, fairly steep side slopes (3:1) adjacent to the wetland. A pote tial erosion problem exists; therefore, the side slope should be revegetated as soon as possible lafter site grading with erosio'i control blanket. This area will be constructed under the City's improvement project and will be addressed on the construction plans. Regulations The City admini wetland replaces the Wetland Conservation Act (WCA), however it does not appear that a plan will be necessary for this project. Staff would like the following I J 11 Sharmin Al -Jaff August 31, 1994 Page 2 ' information as part of the wetland delineation report: a map with the locations of the wetland data points, at least one data sheet for each wetland identifying upland, and a map of the soils. In addition to the requirements of the WCA, the City also requires a buffer strip and buffer strip monumentation around the wetlands. The buffer strip width required for natural wetlands is 10 to 30 feet with a minimum average width of 20 feet and the buffer strip width required for an ag /urban wetland is 0 to 20 feet with a minimum average width of 10 feet. The principal structure setback for these wetlands is 40 feet measured from the outside edge of the buffer strip. ' SURFACE WATER MANAGEMENT PLAN (SWMP) The City has prepared a SWMP that is in the final stages of formal adoption. The SWMP will ' serve as a tool to protect, preserve, and enhance its water resources. The plan identifies the stormwater quantity and quality improvements from a regional perspective necessary to allow future development to take place and minimize its impact to downstream water bodies. In. ' general, the water quantity portion of the plan uses a 100 -year design storm interval for ponding and a 10 -year design storm interval for storm sewer piping. The water quality portion of the plan uses William Walker Jr.'s Pondnet model for predicting phosphorus concentrations in shallow ' water bodies. An ultimate conditions model has been developed at each drainage area based on projected future land use, and therefore, different sets of improvements under full development were analyzed to determine the optimum phosphorus reduction in priority water bodies. ' In conjunction with final platting and the construction plan review process, staff will require the J g P applicant to supply drainage plans providing the pre- developed and post developed drainage areas along with runoff calculations for pre - developed and post - developed conditions. Storm water runoff from the site shall maintain the pre - developed conditions for a 100 -year, 24 -hour storm duration. Water quality ponds will not be required since this development will connect to the City's construction project. the applicant will be assessed for storm drainage improvements in lieu of SWNIP fees. Storm water discharge to the ag/urban wetland will be pretreated in a ' sedimentation pond to be constructed with the City's project. Detailed drainage plans and calculations indicating drainage to individual catch basins will also be required. Staff believes addifienM eateh basins Ail! be Fequir-ed along Pond View Cou . The grading plan shall also reflect the normal and high water elevations in the wetlands and storm water ponds for both pre - developed and post- developed conditions. Water Ouality The SWMP has established an assessment rate for water quality systems. The cash dedication shall be equal to the cost of land and pond volume needed for treatment of the phosphorus load leaving the site. The requirement for cash in lieu of land and pond construction shall be based upon a schedule in accordance with the prescribed land use zoning. Values are calculated using the market values of land in the City of Chanhassen plus a value of $2.50 per cubic yard for excavation of the pond. This fee is not applicable since the applicant will be assessed for the Sharmin Al -Jaff August 31, 1994 Page 3 Lake Lucy Roa I storm drainage improvements. The appropriate drainage and utility easements should be dedicated on the final plat. , Water Ouantity The SWMP has established an assessment rate for different land uses based on an average, city- wide rate for the installation of water quantity systems. This cost includes all proposed SWMP trunk systems, culverts, and open channels and stormwater ponding areas for temporary runoff , Single- storage. Single - amily residential developments will have an assessment rate of $1,980 per acre. The proposed would then be responsible for a water quantity assessment fee of $35,501 assuming 17.93 acres of developable land. The City will apply credits to the applicant's , surface water quantity fees for construction of improvements in accordance with the SWMP which include such items as outlet control devices, trunk storm sewer pipes, ponding, etc. An analysis of the �WMP fees and Lake Lucy Road assessments will be performed in conjunction with the final plat and construction plan and specification review process. DRAINAGE r The applicant preparation of as petitioned the City to construct Lake Lucy Road. The City authorized I easibility study for the extension of Lake Lucy Road between Trunk Highway ' 41 and Galpin Lulevard (County Road 117). On June 13, 1994, the City Council approved the feasibility study and authorized preparation of construction plans and specifications for Phase I of the roadway improvements. Phase I will include extending Lake Lucy Road from Trunk Highway 41 to the intersection of proposed Pond View Court. The project includes construction of streets, sidewalk, utilities and storm drainage improvements. This development is dependent upon this project in order to develop. Without these improvements the plat is premature. Therefore, preliminary and final plat approval should be contingent upon City Project No. 92 -12 being ordered and bid awarded. This development will be subject to assessment as a result of ' the City's improvement project. The east side of the development is located within the Lake Lucy Watershed which is under the ' jurisdiction of the Riley Purgatory Bluff Creek Watershed District. The west side of the development is within the Lake Minnewashta Watershed which is under the jurisdiction of'the Minnehaha Creek Watershed District. It appears the runoff from the site will drain into the , ag /urban wetland. The ag/urban wetland will then drain into the natural wetland. The natural wetland drains to the east through a series of other wetlands before it eventually discharges into Lake Lucy.

This will be modified on the City's construction plans. GRADING The site contains a significant grade variety of elevation changes and vegetation. There are steep slopes in the northwesterly and southerly portion of the site. The proposed plans show extensive grading to develop the site for house pads and streets.

This segmCnt of roadway will be built under the City's Improvement Project No. 92 -12. Lake Lucy Road is considered a collector street based on the City's Comprehensive Guide Use , Plan. It is also part of the City's Municipal State -Aid Route. According to the City's subdivision ordinance, direct driveway access onto !;a collector street should be restricted or controlled whenever feasi e. Due to topographic constraints, staff believe there is no other feasible access ' point available to these three lots. Staff is comfortable with Lots 1, 2 and 3 having driveway access onto Lake Lucy Road. Staff is !also recommending that development of Outlot BA, ' depending on tt a future alignment of Lake Lucy Road, may be required to utilize the interior street (Pond View Court). The extension of Lake Lucy Road east of jPond View Court has not been finalized. The City has , prepared a feasi I ility study for the extension of Lake Lucy Road to Galpin Boulevard. There are two other parce s of land that are directly'; impacted by the future alignment of Lake Lucy Road. , The first parcel (Ryan) is located just east of this development. The other parcel (Mancino) is located northeast of this development. Staff has reviewed with the property owners several options for access to the Mancino parcel. Staff has also met with the Ryans and discussed two ' potential alignments for Lake Lucy Road which impact the development potential for the Ryan parcel. There i5 no clear -cut alignment that satisfies all of the property owners in this situation. The Ryans have submitted a preliminary plat for review.

About half of the wetland extends off -site to thewest; approximately 5.17 acres of wetland is on site. This wetland is DNR protected water, b -132W. An ordinary high water mark has not been established for this wetland. Southeast Banns a large, nat{uat weand, locatcl the southeaste co�l✓r of the, property. The majority of the wetla=nd is off -site with only approximately 2.03 acres on-srte ,It -elves not appear that the wetland will be impacted as a result of construction of Lake LACY lead, however, it is very important that type III erosion" oontrol be constructed , 06biW the wetland and well ' maintained during construction. There will be omefair y steep side slopes (3:1) adjacent to the wetland. A potential erosion problem exists, �,ffierOpfore, the side slope should be revegetated as g soon as possible after site grading with erosic���ontrol blanket. This area will be constructed under the City's improvement project and will be addressed on the construction plans. ' Regulations The City administers the Wetland Conservation Act (WCA), however it does not appear that a wetland replacement plan will be necessary for this project. Staff would like the following ' information as part of the wetland delineation report: a map with the locations of the wetland data points, at least one data sheet for each wetland identifying upland, and a map of the soils. t Sharmin Al -Jaff August 4, 1994 Page 2 In addition to the requirements of the WCA, the City also requires a buffer strip and buffer strip monumentation around the wetlands. The buffer strip width required for natural wetlands is 10 to 30 feet with a minimum average width of 20 feet and the buffer strip width required for an ag /urban wetland is 0 to 20 feet with a minimum average width of 10 feet. The principal structure setback for these wetlands is 40 feet measured from the outside edge of the buffer strip. ' The City has prepared a SWMP that is in; the final stages of formal adoption. The SWMP will serve as a tool to protect, preserve, and enhance its water resources. The plan identifies the stormwater quantity and quality improvements from a regional perspective necessary to allow , future development to take place and minimize its impact to downstream water bodies. In general, the water quantity portion of the plan uses a 100 -year design storm interval for ponding and a 10 -year design storm interval for storm sewer piping. The water quality portion of the plan , uses William Walker Jr. 's Pondnet model for predicting phosphorus concentrations in shallow water bodies. An ultimate conditions model has been developed at each drainage area based on projected future land use, and therefore, different sets of improvements under full development were analyzed to determine the optimum phosphorus reduction in priority water bodies. Water Quality The SWMP has established an assessment rate for water quality systems. The cash dedication shall be equal tc the cost of land and pond volume needed for treatment of the phosphorus load leaving the site. The requirement for cash in lieu of land and pond construction shall be based upon a schedule in accordance with the prescribed land use zoning. Values are calculated using r the market values of land in the City of Chanhassen plus a value of $2.50 per cubic yard for excavation of the pond. This fee is not applicable since the applicant will be assessed for the Lake Lucy Roa4 storm drainage improvements. , Water Quantity , The SWMP has established an assessment rate for different land uses based on an average, city- wide rate for the installation of water quantity systems. This cost includes all proposed SWMP In conjunction applicant to supply with final platting and the, construction plan review process, staff will require the drainage plans providing the pre - developed and post developed drainage areas along with runoff calculations for pre - developed and post - developed conditions. Storm water , runoff from the site shall maintain the pre - developed conditions for a 100 -year, 24 -hour storm duration. Water quality ponds will not be required since this development will connect to the City's construction project. the applicant will be assessed for storm drainage improvements in ' lieu of SWMP fees. Storm water discharge to the ag /urban wetland will be pretreated in a sedimentation pond to be constructed with the City's project. Detailed drainage plans and calculations indicating drainage to individual catch basins will also be required. Staff believes additional catch basins will be required along Pond View Court. The grading plan shall also reflect the normal and high water elevations in the wetlands and storm water ponds for both pre - developed and post- developed conditions': Water Quality The SWMP has established an assessment rate for water quality systems. The cash dedication shall be equal tc the cost of land and pond volume needed for treatment of the phosphorus load leaving the site. The requirement for cash in lieu of land and pond construction shall be based upon a schedule in accordance with the prescribed land use zoning. Values are calculated using r the market values of land in the City of Chanhassen plus a value of $2.50 per cubic yard for excavation of the pond. This fee is not applicable since the applicant will be assessed for the Lake Lucy Roa4 storm drainage improvements. , Water Quantity , The SWMP has established an assessment rate for different land uses based on an average, city- wide rate for the installation of water quantity systems. This cost includes all proposed SWMP Sharmin Al -Jaff August 4, 1994 Page 3 1 trunk systems, culverts, and open channels and stormwater ponding areas for temporary runoff storage. Single - family residential developments will have an assessment rate of $1,980 per acre. The proposed development would then be responsible for a water quantity assessment fee of $35,501 assuming 17.93 acres of developable land. The City will apply credits to the applicant's surface water quantity fees for construction of improvements in accordance with the SWAP which include such items as outlet control devices, trunk storm sewer pipes, ponding, etc. An analysis of the SWAP fees will be performed in conjunction with the final plat and construction plan and specification review process. ' DRAINAGE The applicant has petitioned the City to construct Lake Lucy Road. The City authorized ' preparation of a feasibility study for the extension of Lake Lucy Road between Trunk Highway 41 and Galpin Boulevard (County Road 117). On June 13, 1994, the City Council approved the ' feasibility study and authorized preparation of construction plans and specifications for Phase I of the roadway improvements. Phase I will include extending Lake Lucy Road from Trunk Highway 41 to the intersection of proposed Pond View Court. The project includes construction of streets, sidewalk, utilities and storm drainage improvements. This development is dependent upon this project in order to develop. Without these improvements the plat is premature. Therefore, preliminary and final plat approval should be contingent upon City Project No. 92 -12 ' being ordered and bid awarded. This development will be subject to assessment as a result of the City's improvement project. The east side of the development is located within the Lake Lucy Watershed which is under the jurisdiction of the Riley Purgatory Bluff Creek Watershed District. The west side of the development is within the Lake N innewashta Watershed which is under the jurisdiction of the ' Minnehaha Creek Watershed District. It appears the runoff from the site will drain into the ag /urban wetland. The ag /urban wetland will then drain into the natural wetland. The natural wetland drains to the east through a series of other wetlands before it eventually discharges into ' Lake Lucy. Since the Minnehaha Creek Watershed and the Riley Purgatory Bluff Creek Watershed boundaries are being altered both watershed districts and the Board of Water and Soil Resources should be informed of the alterations proposed to the watershed boundaries. ' The storm water runoff from the front yard areas and street will be conveyed via storm sewers into a sediment basin that the City's improvement project will be constructing prior to discharging ' into the ag /urban wetland. A sediment basin will be designed with the City's project to hold back sand and silt running off from the proposed development and the Lake Lucy roadway before it enters the ag /urban wetland. Staff believes that a sediment trap is sufficient water quality treatment in this situation; however, the inlet from the sediment trap to the ag/urban wetland should be located well away from the outlet that discharges the ag/urban wetland into the natural wetland. This will be modified on the City's construction plans. GRADING Sharmin Al -Jafi August 4, 1994 Page 4 The site contains a significant grade variety of elevation changes and vegetation. There are steep slopes in the northwesterly and southerly portion of the site. The proposed plans show extensive , grading to develop the site for house pads and streets. A development plan should be prepared or included with the grading plan indicating the type of dwelling to be built on each lot. There are some very steep slopes in the northwest corner of the development that will be re- graded t under the proposed plan. Staff recommends that the street be extended to provide future access to the Mancino property at the northeast boundary. This will provide access which can be extended east through the Mancino property in the future. Staff reviewed another potential location for this access road at the southwest corner of the property (Outlot A); however, the slopes leading into the Mancino property here are very steep and resulting road grades would be greater than 10 percent. The extension of Pond View Court appears to be the best alternative , since it would eliminate steep road grades and allow some natural resource continuity between the wooded area on Mancino's property and the ravine which extends from the wooded area south to the wetland. The road crossing the ravine would occur on the north end where the ravine , begins. We believe this alignment will 'minimize impact to the surrounding property and still provide a feasible access. , The applicant mill need to develop a sediment and erosion control plan in accordance with the City's Best Management Practice Handbook (BMPH). Type III erosion control fencing will be required around the natural wetland. The steep slopes may also require some form of terraced , erosion control encing. The plan shall be submitted to the City for review and formal approval in conjunction with final plat approval.. The City has adopted a Best Management Practice Handbook which the applicant can purchase from the City at a cost of $25 to assist with the , design process. UTILITIES ' With the constr�Zction of Lake Lucy Road, sanitary sewer and water lines will be extended to serve this development. pment. Staff has reviewed different alternatives to provide the Mancino parcel ' with street access and utility service. Whichever option is approved, staff recommends that the applicant be req parcel. The utility fired to extend utilities along with access for future extension into the Mancino plans are relatively straightforward. Water service may be connected from the existing line at their northerly propery line or extension from Lake Lucy Road depending on the road extension. Staff may require the looping of this water line. A detailed analysis of the construction plans ' will be performed in conjunction with the final plat submittal process. Fire hydrants shall be placed a maximum of 300 feet apart. All utility construction shall be in accordance to the City's latest edition of the Standard Specifications and Detail Plates. Detailed construction drawings and specifications for the utilities and street improvements will be required for submittal with final plat approval. The construction plans and specifications will be subject to staff reviewed City Council approval. In conjunction with the final platting process, the City applicant will by required to enter into a development contract with the and provide the 77 LIB 1 1 17 LI Sharmin Al -Jaff August 4, 1994 Page 5 necessary financial security to guarantee installation of the public improvements and conditions of final plat approval. STREETS Access to the development is proposed from Lake Lucy Road extending from Trunk Highway 41. This segment of roadway will be built under the City's Improvement Project No. 92 -12. Lake Lucy Road is considered a collector street based on the City's Comprehensive Guide Use Plan. It is also part of the City's Municipal State -Aid Route. According to the City's subdivision ordinance, direct driveway access onto a collector street should be restricted or controlled whenever feasible. Due to topographic constraints, staff believe there is no other feasible access point available to these three lots. Staff is comfortable with Lots 1, 2 and 3 having driveway access onto Lake Lucy Road. Staff is also recommending that development of Outlot A, depending on the future alignment of Lake Lucy Road, may be required to utilize the interior street (Pond View Court). The extension of Lake Lucy Road east of Pond View Court has not been finalized. The City has prepared a feasibility study for the extension of Lake Lucy Road to Galpin Boulevard. There are two other parcels of land that are directly impacted by the future alignment of Lake Lucy Road. The first parcel (Ryan) is located just east of this development. The other parcel ( Mancino) is located northeast of this development. Staff has reviewed with the property owners several options for access to the Mancino parcel. Staff has also met with the Ryans and discussed two potential alignments for Lake Lucy Road which impact the development potential for the Ryan parcel. There is no clear -cut alignment that satisfies all of the property owners in this situation. The Ryans have submitted a preliminary plat for review. They have utilized the northerly alignment of Lake Lucy Road through their parcel. Staff has reviewed this preliminary plat and finds numerous problems from a design standpoint that will have to be revised, thus reducing the potential number of lots. Staff has also reviewed the southerly alignment of Lake Lucy Road through the Ryan parcel which leaves the westerly portion of the site very difficult to develop due to very steep slopes. The resulting impact requires short, steep cul -de -sacs as well as tuck - under type homes versus walkouts overlooking the wetlands. Staff has put together three options that we see feasible for development of these three parcels ( Brenden Pond, Mancinos and Ryans). Option A - Pros (See Attachment #1) This alignment follows the City's feasibility study which minimizes grading and tree loss adjacent to the wetlands through the Ryan parcel. This alignment also allows for two options to extend the street access to the Mancino's parcel and further develop Outlot A, Brenden Pond from interior street versus Lake Lucy Road. One access would be through the southerly portion of the Gestach development along the ravine, although street grades in this alignment may be in excess of 10% and involve additional tree loss and filling of the ravine. The other option to access Mancinos could be to extend Pond View Court to the northeasterly corner of the Gestach plat for future access. This access is much less severe in grade, involves some tree loss and filling of t Sharmin Al -Jaff August 4, 1994 Page 6 ' a portion of the ravine and single - loaded!, lots. The northerly extension into Mancinos preserves the natural feat res of the southwest portion of Mancinos. , U ton A - eons I The Lake Lucy Road alignment is not conducive with the Ryan's proposed plat. This option leaves the Ryan parcel to develop with cul -de -sacs north of Lake Lucy Road which will involve steep grades and tuck -under type homes at the end of the cul -de -sacs. Another scenario would be to delay development of these northerly cul -de -sacs until the Mancinos develop from the north. Access to this area is more conducive from the north in order to situate homes at the top of the , ridge. Option B - Prod (See Attachment 92) This alignment is conducive to the Ryan's preliminary plat although the Ryan's preliminary plat is anticipated to be revised due to inadequate intersection spacing along with wetland mitigation ' measures and storm ponding issues. Option B - Cons This roadway 4ignment does not follow the City's feasibility study. This alignment will push Lake Lucy Road further north resulting in steep slopes along the north side of Lake Lucy Road , and mass grading which will significantly alter the existing terrain. This option will also limit access to the Mancino parcel from the extension of Pond View Court. (lnf;nn r - Pnni (Cps- Aftarhmant:HAI , This option follows the City's feasibility study, maintains the existing topographic features by minimizing gra ing and provides development flexibility to the Mancino parcel Option C - Cos ' This option delays development of the westerly portion of the Ryan's plat until access is provided through Mancirio's property. 1 Conclusion I Staff has revie ed these options and concluded that Option C should be implemented. This leaves development flexibility to the Mancino parcel and allows both parcels (Brenden Pond and Ryan) to develop. Staff believes it is an appropriate way to develop the westerly one -third of the Ryan development. Due to steep grades, we believe that this site should be accessed from the north to retEin its topographic features. If the Mancino parcel was the first to be developed, ' we would recommend that the Mancinos provide a street access to the south for development of this area due to the steep grades. Similarly, staff has required the Ryans to provide access to the Sharmin Al -Jaff August 4, 1994 Page 7 Carlson parcel (south of Jennifer Way) due to the isolated parcel of land (surrounded by wetland). ' We feel that it is in the best interest of the City and property owners to make a development proposal which utilizes the existing topography. In addition, the Ryan plat needs to go back and be substantially reworked due to intersection spacing, wetland setbacks, wetland mitigation areas and storm ponding issues. The applicant is proposing to dedicate an 80 -foot wide right -of -way for the construction of Lake ' Lucy Road through the development. The plans also propose a 60 -foot wide right -of -way and construction of the City's standard roadway section for Pond View Court. This typical section will allow for sufficient room for sidewalk if so desired to access Lake Lucy Road to the school ' immediately north of the development. Street grades range from 0.5% to 7% which is the City's maximum grade allowed. Detailed construction plans and specifications for the street improvements will be required as part of the final plat submittal. Should access to the Mancino parcel be considered through the north end of Pond View Court, then the road should be extended to the northeast boundary of the plat where a temporary cul -de -sac should be built with a sign and a barricade indicating that this street will be extended in the future. Staff also recommends that if the road is extended to the northeast corner of the plat for future extension, the street name should be modified to either Pond View Lane other than designated as Court. RECOMMENDED CONDITIONS OF APPROVAL ' 1. The proposed development will be responsible for a water quantity assessment fee of $35,501 assuming 17.93 acres of developable land.

I have no financial interest in it but I do care about what happens so I'm going to remove myself, if that is fine with you. I talked to the City Attorney and kind of gone over this with him and will take my place as a private citizen and speak from that point of view. Scott: Good, thank you. In view of similar things on other parts of city government, that is definitely appreciated but does not surprise me. Thank you very much. Sharmin Al -Jaff presented the staff report on this item. Harberts: What's the, excuse me. What's the comment by public safety on this issue. I'm trying to determine traffic flow and then stacking up here. Has staff looked at that? Hempel: One of the issues that's been brought up in the subdivision before us this evening that is being addressed, that the intersection spacing was. 5 /- Planning Commission Meeting - August 17, 1994 Hempel: Yeah. We looked at the topographic maps and it was extremely steep and then I ' believe the Mancino's had hired an engineer's office to do that as well. The grades were pretty significanI for this swath. The street would be 100 feet or so in that area. We felt that that was not a feasible route for a city street to go. Scott: How do . ou feel about that? r 6 I Harberts: Pretty tight. did It be Hempel: On their submittal, yes. We point that out. would sufficient, we would revise the drawings and get additional space. ' Aanenson: I'd Ike to make a couple of comments as far as the options. What happened with this is we had the Gestach - Paulson party who wanted to go forward with the plat ... Lake Lucy extension. Having done that, the Ryans put themselves in a position where they want to ' make sure the road that they're designing so they were ready to develop. Well that left us with the concern, is well now Mancino's is the last big missing link here and ... we needed to make sure that access is provided for all properties. If the Mancino's to come in first we would say okay, you need to now provide access to Gestach- Paulson property and to the Ryan's property so all three parties have been very cooperative and we've spent a lot of time. It's been very d' icult. We've kind of wrapped each ... issue here as far as on this subdivision ' but they're all inter related. So we tried to make sure that each subdivision provides access to the adjoining property. It is a complex issue and we're not sure that we've got all the answers but we've tried to give some options that we think may work. There's some steep slopes on this property. Significant grade changes. Some natural features. Wetlands. Heavily wooded areas that we had to preserve. So it is complex but on this, the Gestach- Paulson property, we feel that however we get access to the Mancino's, there is one outlot , that was platted on the Shivley addition. ''We're not sure but ... would be to the north into the Mancino's so w 're saying somewhere, either through the Ryan's subdivision or through the Gestach - Paulson subdivision, access need's to be given to the Mancino property. And that's why Commissioner Mancino removed herself from this because we're insisting that, whether they develop or if they would sell at some time in the future, somebody may want a public street through there. It may not be them but somehow we need to insure that there's access to that property and we're not land locking them so that's why this issues is before you with this subdivision. ' Scott: Just a question. Dave, with the alignment that we see here having access to the Mancino propery from it looks like between Lots 20 and 21. Is that slope going to be, is it going to be, is it going to be about a 10% grade street or 15% or something like that? Hempel: Yeah. We looked at the topographic maps and it was extremely steep and then I ' believe the Mancino's had hired an engineer's office to do that as well. The grades were pretty significanI for this swath. The street would be 100 feet or so in that area. We felt that that was not a feasible route for a city street to go. Scott: How do . ou feel about that? r 6 I Planning Commission Meeting - August 17, 1994 Hempel: I would concur with that. I believe there are better alternatives to serve the Mancino parcel than bisecting it in that specific location. Scott: Would you, I mean just from looking at the maps that we are provided, does it appear, at least if we're looking at access from a westerly or southwesterly portion, would you agree ' that a connection between Lots 15 and 16 would topographically would yield both the access with a minimum amount of disturbance. I mean we don't, obviously we're trying to allow three different land owners to develop responsibly here but just dealing with the access from ' the westerly side, does it appear that going between Lots 15 and 16 is one of the better alternatives? Hempel: It is a better alternative than the southerly one, definitely. There are a couple drawbacks with that one as well. It would be a single loaded street. The school property is directly to the north. If the Mancino's develop, they may not even elect to .use that option. ' They may loop the street back internally but at least we're providing an access with the utilities for future extension if so desired. ' Scott: Is there enough distance inbetween, now we need a quarter of a mile inbetween access to county road? What is the distance requirement? Hempel: In this subdivision here we're looking at 300 foot intersection spacing. The quarter mile refers to arterials like Trunk Highway 41. Scott: Okay. So there wouldn't be really anything that would preclude an access point to the Mancino property off of CR 117 that was somewhere in the middle of their, I know there's ' an existing driveway or something like that. Aanenson: And that would be one access.- They would have direct access out onto Galpin. What we're saying is, if that was their only access point, let's say. Scott: Well yeah, you need. ' Aanenson: You would have a long dead end cul -de -sac and that's our ... there needs to be another access point into the Ryan's piece which can ... or up through the extension of the cul- tde -sac from the Gestach- Paulson property. Scott: Okay, thank you. Al -Jaff: We are recommendin g approval of this subdivision with conditions outlined in the staff report. I have some minor changes to some. One ... where the applicant needs to shift 7 r Planning Commission Meeting - August 17, 1994 some property lies to give some... adequate frontage. We also apologize for not forwarding the grading plan to you. If there are any questions regarding the grading, it's fairly simple ' and if there are y questions regarding the grading, we will answer them. With that we are recommending proval of the plan with conditions outlined in the staff report. Scott: Good, thank Y ou. Any comments, from commissioners? Hearing none, would the ' applicant or thei- representative wish to speak at this time? Yes sir, please state your name and your addres please. , David Gestach: David Gestach ... we've been working with staff and the adjoining neighbors and like they say, it's been a long process. The first plat was submitted back in '85. That ' was in 2 1/2 acre lots and then—so it's been a long process so we're appreciate your approving the plan. It's basically the same layout as far as...but I guess that's all I have to say. ' Scott: Good. Any questions for the applicant? Good, thank you very much. willing to provide a public street to the ' David Gestach: And the other thing is, we g p p adjoining property owners. Scott: Okay. Good, thank you. This is a public hearing. May I have a motion to open the public hearing? ' Conrad moved, Nutting seconded to open the public hearing. All voted in favor and the motion carried. The public hearing was opened. Scott: If anyon would wish to speak, please step forward. Give us your name and your address and tells what's on your mind. Steve Buresh: My name is Steve Buresh: I'm more directly interested in the next item but this one does impact me somewhat since ',I do live on Galpin Blvd. I do have a few concerns with having liv in this area since 1987 !in the Lake Lucy Highlands area. And in that the concerns are with the extension and then ;with the two additions that are planning to go in there. Currently we already, as someone who tried to get onto Highway 5 every morning, we , currently have some extreme traffic problems out there in that area and I think that the Planning Commission should definitely take a look at the approvals of additions out there with the current I status of Highway 5 and, the fact that it's only 2 lane out there. And then , also what, basicoly what impact this, all these homes going into this area are going to have. Scott: So you're concerned about your access from CR 117? , e 1 i Planning Commission Meeting - August 17, 1994 ' Steve Buresh: Well with the continuation of Lake Lucy Road there. I'm just about 4 houses down from the intersection of Lake Lucy, the current Lake Lucy Road and Galpin Blvd. The traffic that's going to end up being dumped onto Highway 5 to the south there and then also currently with the traffic that's going through that area right now in the rush hour period. So I just want to voice that we should take into consideration the current roads out in that ' area before we start expanding that at too large a rate. Scott: Okay. Dave, do you want to talk about the signalization project this fall? ' Hempel: Certainly Mr. Chairman. The projection with the new elementary or middle school being constructed at the southeast corner of Trunk Highway 5 and Galpin Blvd, there will be construction and installation of a signalized intersection there to assist traffic in crossing Highway 5. This project and Lake Lucy Road extension will actually probably assist in some of the traffic. Right now you only have one access and that's going south with the extension ' of Lake Lucy Road through and provide a parallel street system to Highway 5, approximately a 1 1/2 mile north of Highway 5 to give another option to access TH 5 as well. But we are well aware of the traffic concerns at the intersection of Galpin and Trunk Highway 5. We're ' working on resolving that. Scott: Okay, so that signal will be installed yet this fall? ' Hempel: Early 1995. ' Scott: Okay, good. Does that answer your question? Steve Buresh: Yeah. That concludes my concerns. Scott: Good, thank you sir. Would anybody else like to speak at the public hearing? ' Sam Mancino: Hi, I'm Sam Mancino, 6620 Galpin Blvd... Nancy Mancino: Mr. Chair, Nancy Mancino, 6620 Galpin Blvd. Sam Mancino: First off we'd like to make it clear that we at this time have no intentions to ' develop. We are merely trying to do some long range planning. As the development around us sets in, it becomes clear that we have to apply certain prudent ...how we deal with this property and allow for future contingencies. But at this time we don't have any definite plans but we have done some drawings and some planning to ... decision. In the process we've talked to a lot of experts and engineers as well as staff... sketched this and we want to kind of walk through some of the issues as we see them. As it regards, the first part of this area, the 9 Planning Commission Meeting - August 17, 1994 Gestach- Paulson property to the west of us. Both this and as well the Ryan property but basically in terms of the topography for the last many years, working farms has been mostly clearing trees. a rolling topography remains but most of the trees have been cleared. During that sam -,period of time in the 40 "s and 50's, our's was the old Slogan Tree Farm and planted a to of specimen trees. The 'perimeter is pretty much lined by trees and within the site itself there are a lot of very mature trees. The western half is almost completely woods with a ra . e system that runs through it. It makes future development of it possible but as we say so ewhat problematic. We have to deal with and sensitive to it. Our house is located at about a gift point east and west, very close to the southern property line. Scott: If you could angle that. Could you angle that straight at us so the camera can pick it up from behind. There are cameras everywhere so be careful. Sam Mancino: y the way, this is Charles Stinson who is an architect who will be helping with the present lion and planning. There's a perimeter tree line that runs the entire east/west portion of the southern property line. Many of you who drive Galpin Boulevard probably are familiar with tht large stand of arborvitae trees that line the western side of Galpin Road. There's a companion set of arborvitae through here. This entire section is woods and will be ... through here, that will meander back into here. The terrain rises somewhat sharply here to a high point. The section near our house is probably at 1,050 -1,060 feet and this property falls off down i to the 960's I believe or 980's. It's about an 8 foot drop there so just to give you an ove all sense of the terrain. Through here there are a lot of stands of Ponderosa pines... As a cor sequence, most of the people who have advised us about looking at our future developm nt potential, both developers, architects, and engineers, have really come pretty much to tie same conclusion which is whatever is happening here, we should probably consider that whatever development we do in our property will be somewhat different than the surrounding evelopments. Both in terms of the lot sizes, which following the landforms and the natural trees and vegetation...force themselves into a larger lot configuration than we see being plattec around us. And so our long range thinking is that we will probably tend to develop that as an eye per se. More self contained and for that purpose we probably don't want to go thro gh ... adjoining properties. We've looked at a number of road options. We've been in some di -,cussions with the Gestach - Paulson and Lee and have at one time looked at a variation that su f had talked about us with which had us accessing a road system through here, or a road stem through here to serve this property. And perhaps Charles, maybe you can talk to us about some of the things that's happened as a result of that road system Charles Stinson: Eastwood Road that property fro understanding th Okay. My name is Charles Stinson. I'm an architect and I live at 4733 i Minnetonka. I was approached by Nancy and Sam about taking a look at i an architectural standpoint, from a land planning standpoint and with the t none of us wanted to do a maximum density residential area and we 10 t r �I L 1 CSI I�� i C �L� Planning Commission Meeting - August 17, 1994 wanted to keep and save the integrity of the area. I mean it's, with all the development going everywhere and with trees coming down and topography being ripped apart, we wanted to save one of the last stands of just specimen trees. I mean there's huge ponderosa pine. Across this area, I mean they're just gigantic. There's a big ravine and again there's 80 feet of drop going from here to down in this area. A lot of, there's pathways. Just a tremendous amount of trees that were planted 40 -50 years ago and they go all the way across the property. This is totally dense. Kind of an unmolested nature in this area and they actually extend across the property line. So as we looked at it, the first thing we wanted to think about is, as we get back to the road, was just the idea of what can we do to preserve the integrity of this whole area without destroying it. And with the buffers we're thinking, at the beginning point is, creating a conservation zone that would occur on both our property and the properties abutting that would be desirable for everybody. You know perhaps 30 feet on each side or something but it would be far enough away that it wouldn't destroy the root system and that's one of the problems of so many of our developments is we go in and we say well, we're going to miss that tree with the road but by the time we do the grading, it gets wider than we think and dirt is you know knocking the oxygen out of the roots or the earth below the tree and we lose not only where we've just placed the trees but we've damaged everything around it that we'll lose it within a couple years. So trying to preserve their root system for everything around, for everybody in the neighborhood. So the idea, and in looking at this and the other, we can look at a concept here of the road but to give you a feeling of how they live there ... have lived here for the last 10 or 12 years, is there's a private drive that comes in here. Drive through past the existing houses and reaches their house. In going in there, so you're just cutting right through the trees. It's just beautiful and very private. And when you arrive at the house, there's a giant meadow that's just going all the way across here that just goes on forever. There's also a large meadow behind their house and wildflower garden and then again the path system going through here is just, you really should take a look at the property. So in looking at it, I can address this road alternative but this is an example of what can happen I think just about anywhere where a large street comes through the site. But an engineer took a look at this and showed us the topography so I've just identified the area of the trees that certainly would be lost. And to see that, I mean it's a major displacement of that forest. And even if a natural road came in the top, it would do pretty much to the top what the same at the top did and all the ponderosas that seem to be here and here would be gone. And it's right next to the school field and it's exposed to the fence and all that. So it didn't seem like a real good alternative. So what we looked at. Sam Mancino: One other point. In addition to just knocking out the trees, because of the grades. We'd have to probably be either outside ... 10% grade in some cases which would require, I think that requires cutting down of 10, 12, 14 feet. Being able to fill with 16 feet up in places and being able to ... across the whole ravine system so it seemed a bit of a violation to the topography. 11 Planning Commission Meeting - August 17, 1994 t Charles Stinson:1 So in a very cartoon form, this is what we were thinking of. We were thinking if it had to, and we were trying to come up with stages that would happen so the , Mancino's could live in their house with 'the same integrity that they do now and the site. So we thought if, there are several components here but the ravine is so big and this is so dense and the topography is dropping down so much this way and that way, that the service is ' dipping down h re. The best way to service this side, instead of bringing a road all the way through, would having a two private drives off the west side of the property. One coming up here and wo.11d service this lot and this lot with each of them are good sized lots. I'm not ' sure of the exact acreage they would be. Sam Mancino: Probably 3/4 of an acre. ' Charles Stinson: Yeah. And another one coming up at the top. So it would just be a private drive and utilities so anything brought up would actually stop at the conservation line instead , of wrecking the trees with these. If it doesn't happen and then at some point we would bring them in. And then the other access point would be in kind of a phase one but would be just coming off this existing road up here. That neighborhood and coming out with one cul -de- ' sac that would s rvice here, here and here with a private drive going to that lot so we could work the homes built in a real ... solution into the existing topography. And then leaving this all the same as it exists in the middle and just bringing in a short road and a cul -de -sac here. ' Just servicing th se lots and keeping and using this, what would be the future road, as a private drive going kind of a neutr to these lots temporarily and that would leave this whole meadow area as open zone and that way' we'd be leaving all the trees here, all the trees here. ' As much of this as we possibly can all in this except for where the road can come in. Mancino's would continue to use their existing private drive coming in and enjoy this area. At some point they ' retire and move out to the country or something, they could put this road all the way through. Connect the two of,them and divide this up into lots and they would have a thru street here and a short cul -de,- -sac at this point. But from the lower portion, just ' bringing up utilises because the topography is ... bring the utilities in here. Instead of having a thru road going through here, just have the utilities again stop at the bottom of the conservation lmQy and I'm getting ahead of myself on this next site but it's all so integrated ' bring it There is that it's doing the same thing here. That way we could up. a short open space just by thi -, arborvitaes here. Just on the back side of it that there isn't anything. So we could bring it right across there and if we need to go across, we could just kind of tunnel ' underneath the ees as opposed to making the big hole there. Sam Mancino: s it relates to the future; possibility to hook up to Crestview. Some years , ago we were requested to come to the city Planning and City Council meeting and we have a note from February 7, 1990 which made a City Council recommendation that at such time that this plat wai filed, that it should be amended to provide the right -of -way for the ' 12 ' i Planning Commission Meeting - August 17, 1994 ' extension of Crestview Road ... feet which basically though it doesn't lock in the exact location of the road, either positions it through here or possibly through here as long as there are some ' proper buildable lots. So I think that there is some notice in the record that that is a strong preference from staff at one point that recommended that we hook up at that time. ' Nancy Mancino: Yes, that is true. That when the Shivley's went in and did, I think it was a subdivision in here. That staff asked to make sure that we had access to the north. And the particular road alignment, where that access is. Whether it's between here and there, it was ' not drawn out. It was not stated exactly where it is. That there is an outlot that was created to have a roadway to go into the new property. But the exact location is between there and there ... very comfortable that if it isn't right here, it could come over the cul -de -sac and also ' allow for our entering onto Galpin and there would be two accesses into the property so there would not be a long cul -de -sac. Sam Mancino: Just to reiterate my point. Though we've looked at the possibility of bringing in a flow through road, we do believe that we, long term will serve the community's needs to flow a road through into Crestview, which will create the circulation and the need. The other thing is that in terms of violating and ripping and tearing the property, there's two discreet private drives that would be built to city roadway standards would probably be ... virtually no different than a road easement for full service roads. We don't feel that that's much of a burden on the adjoining property owners and we have offered to help in landscaping the road. The private drive going in there to be able to minimize the impact on that. And it also facilitates a better sequence of any future development, whether it's ourselves or someone else in the future because there are a number of options for sequencing in this area. Nancy Mancino: No, I don't think there is. As just stated, we would recommend that under the condition of the staff approval that number 28 be changed. Instead of having a street access off the, the applicant shall provide a right -of -way and street and utilities to the east ' boundary of the plat and tying in a temporary cul -de -sac which will be signed on barricades to indicate this street shall be extended in the future. That we do recommend that two accesses, two private drives between Lots 15 and 16 and Lots 19 and 20 ... be approved. Also ' there be a 30 foot conservation easement on the perimeter of the property that abuts the Gestach- Paulson property. , ' Scott: And from looking at the staff report, you've discussed the private drive issue with the Gestachs and they've. Sam Mancino: We haven't. Unfortunately haven't been able to work out all of the details of that. As they said, they are, as I understand, they are more than willing to bring a road up at either of the locations. In some conversations we've had we have asked for two private 13 Planning Commission Meeting - August 17, 1994 drives in lieu of a single road. At our latest discussions, I think that they would prefer a single road, full sized... Scott: Okay. Nancy Mancino:� Any questions? Sam Mancino: Any questions? Scott: Okay, thank you. Would anyone else like to speak at the public hearing? Yes sir. Lee Paulson: TV y name's Lee Paulson. I live in St. Bonifacius. Gestach - Paulson Construction. We've already gone over this private driveway stuff. My partner's talked to staff and talked to Mancino's an our experts tell us that it would ... our development by having these private driveways runniig through our development. We don't want private driveways. We agree with staff with Option A or B. We just don't want these private driveways in there. I don't believe staff ready wants these driveways. The way I understand it, want the driveways either and we'd a to see this moved on to, voted on and moved on to the next step. Thank you. Scott: Thank you. Would anyone else like to speak at the public hearing? Steve Buresh: I would like to comment. Scott: Well whi don't we see if there's someone who would like to speak first. Or for the first time. Yes sir. Peter Davis: Yes, my name is Peter Davis. I live at 6640 Galpin Boulevard which is that kind of odd shaped, ed, rectangle in the upper right corner. I just wanted to be recognized as an interested party. I haven't been involved] with the other discussions and just to save my remarks for item 3. Scott: Okay. make your cc Steve Buresh: l pretty much go that is the area 1 is 2 1/2 acres ar that are being pi you. Anybody else like to speak at the public hearing? Sir, if you can extremely brief then. Jow that it's been outlined here and made a little bit clearer, since this does Tong with the concerns that I have for the next item on the agenda too and hat adjoins Galpin Boulevard there. This whole area along Galpin Boulevard d larger lots and I think that, I don't know exactly what the size of the lots -oposed for this section, for that small pan handle section there that runs up to t n 14 1 IPlanning Commission Meeting - August 17, 1994 ' Galpin Boulevard but I would strongly recommend that those lots be no smaller than an acre and a half in order to fit in with the aesthetics of the area. This area is also very, there's very ' much wildlife in the area. I've got deer that go across my property all the time. That's one of the reasons that I moved out there. I was raised on a farm so I like the open spaces and basically I feel that that probably is the reason a lot of people are out there with the large ' sized lots. So I guess I'd ask the Planning Commission to monitor what size those lots should be in the panhandle section there of that development to make sure that those are, would fit in with the area. Scott: Good, thank you. Would anyone else like to speak at the public hearing? Seeing none, may I have a motion to close the public hearing please? Ledvina moved, Conrad seconded to close the public hearing. All voted in favor and the ' motion carried. The public hearing was closed. Scott: Ron. ' Nutting: I guess I haven't, perhaps I...what is staff's reaction to the private drive issue? Hempel: Maybe I can address first from a utility standpoint. Depending on the length of a private driveway, it's typically 200 feet is probably maximum for the sewer and water extension for a single service. The ... we looked at servicing additional lots and properties and ' trying to get a full sewer line or a water line in there... The other issue is basically ... for a single lot or two lots for a private driveway that responsibility is with that homeowner to maintain that line. Whereby if it's a city street, it's obviously maintained by the city and so forth. With the roadway extension to the northeast corner of the property, it leaves the option for the Mancino's to either explore a full service street through there or explore stubbing off a private driveway to serve up to 4 lots off of that cul -de -sac. There is significant elevation change from the north end of the property to the south end of the property where it may be somewhat difficult to extend the private driveway down to service that area where the southerly private driveway the Mancino's are requesting. That end there ... will be served internally through a private driveway through the Mancino's but again there's some steep slopes and ravines and the private driveway would have to meander in order to do that. The private driveway would have less environmental effects, less trees, less grading, to do that but the ... so I think staff's position is that we're obligated to look at providing adjacent properties street and utility service and I believe that's what we're doing in this circumstance. Without ' a full fledged development proposal before us from the Mancino's, we really, there's a lot of options in developing the property. The Mancino's are requesting large lots. That's fine. That's great here. It would be nicely preserved with that. There's also potential that the Mancino's would sell the property at some future date to another developer and we would 15 t Planning Commission Meeting - August 17, 1994 have potentially a 15,000 square foot lot subdivision. So it's critical from a street and utility aspect that it provide the infrastructure and street right -of -way to service that for a full I fledged subdivision. Nutting: Did I hear correctly, did the applicant prefer Option A or B and not C? i David Gestach: I Yes. Nutting: ... Option C. Aanenson: Thai was before ... we asked Mancino's to explore whether or not, there was a portion of this plat that is on the Gestach'- Paulson that's called Outlot A. This portion isn't being platted right now. That's a future development... Mancino's looked at going out through there and we asked them to see... Nutting: I thi there are a number of issues here. I think I'm going to defer maybe some of those to the oth ,r commissioners. Scott: Okay, Harberts: I guess just from my perspective, I'm certainly torn with regard to the opportunity to develop the h nd on both parties in the, way that they want to. When I go back or revisit our other plans 1 vith regard to how important it is to the community with regards to it's natural resources, and the uniqueness that exists on the Mancino property. I guess I'm not quite sure. I thilc there's a lot of, I think the commission should maybe have a discussion with regard to some me of those values that we place on our natural resources and see if this might be one of those projects that we might want to have some kind of special consideration because of what we're dealing with. The development itself with regard to the applicant, I guess I'm okay with it in broad concept and I guess my concern lies more with that overall picture, especially when we're dealing with some of those special resources. And I'm just, I'm undecided. 1I really am. Scott: So you Harberts: Well we have a reall; with our other c you know, I me answers but we applicant and tt more time to consider? More time to think about it or. rune is, I think maybe it is a matter of more time to think about it because unique feature here and,when you look at some of the work we've done ;velopments, I think it deserves a little extra special consideration here. And n Kate kind of characterized it well when she said we don't have all the •e trying. Maybe at this point that's all we can do but it sounds like both the Mancino's are trying to work something out. I guess personally I'd like to I- J, �I J 16 1 II u Planning Commission Meeting - August 17, 1994 see this resolved for all parties, including the city. If we're locking ourselves in by some type of approval on it tonight. I'd rather then table it or like I said, see it resolved. If we're in fear of locking ourselves into something if approval is given tonight. Scott: Okay, Ladd. Harberts: Did you find your page? Conrad: I found my page, yeah. I like the staff report. I think they covered most everything. It seems like a good staff report. I like one of the additions the Mancino's made about the tree easement. I think that's important. I think what everybody is talking about is sort of unclear in my mind right now. I'm not really sure. Road alignment for Lake Lucy I think should be as per the original. I don't like Alternative B for Lake Lucy. I like the way it was originally specked and I think that's where it should be. In terms of access to the Mancino property, I really appreciate what they're trying to do. It's a little bit, yeah it's funny you look at it, it's not based on what we typically do here in our bigger lot subdivisions but what they're trying to do is what we endorse. But to a degree it seems a little bit, it's hard to totally grasp what they're trying to do. I'm not sure I understand it yet. I certainly don't mind an access to the north off of the proposed Brenden Pond cul-de -sac going into their property. I'd reduce the number of lots on the plat that I'm currently, on the subdivision that I'm seeing. I think if a road were to swing to the north off of that cul -de -sac, I'd really, I think I'd be eliminating a lot there. And I also, I think there's yeah. I'd be eliminating a lot up there and swinging at least a road or a cul -de -sac into the Mancino property. I'm not sure how to deal with what they're requesting for the private drive to the southwest of their parcel. Bottom line. Like the staff report. Like the tree easement. Road access to Mancino is, I'm up in the air on that. I guess I do want an access on the northwest corner. I'm not sure if it's a private driveway or if it's a connection to that cul-de -sac. If that cul -de -sac literally dead ends into the Mancino property. If it dead ends into it, I'd keep a lot, Lot 15. I want to have a full lot there so that would back up to the school. I don't really know what I'm talking about because I haven't walked the property and I know Matt has so again I guess I'm going to, maybe Matt can persuade us a little bit because I know he's been out there and maybe he has a better feel for it. Scott: Okay, Matt. Thanks. Ledvina: Well the issues that are associated with the plat are real thorny ones and the problem that I see the Mancino's face in terms of their development is that the west part of their property is isolated by a ravine and they feel the need to maintain that landform and also the trees that are associated with that. Because if they go blowing roads through there, I mean they're going to wipe out a tremendous amount of really beautiful area and. 17 Planning Commission Meeting - August 17, 1994 Scott: Can I stop you for just a second? How would this fit in with our bluff ordinance? That ravine. Is that considered a bluff? ' Aanenson: I don't believe it would be, no. Ledvina: I don't think it would, no. Aanenson: Them is a ravine that topographically. I mean we looked at putting a culvert in t there and yes, it does pose a significant... but maybe not. Scott: Okay. I just thought maybe with that ordinance. ' Ledvina: I don't think that comes into play but in terms of the access. I would generally agree with Ladd that the northern access be provided. I don't know about the access towards the southeast co er of the Mancino parcel. I don't know how that would work. There's still, according to the grading plan that the applicant has proposed, there'd be some, it would really run havoc with their grading plan because they do have some steep slopes right in that ' corridor. I don' know. It would almost seem that although the property lines have served to kind of define �e vegetation for landform to the western part of the Mancino property is really with this subdivision or with this parcel. And so it's always hard when the lines get , drawn on the rm ps and I think that's the exact same thing we're going to see with the other parcel to the eas{ and in relation to Mancino's south line there too. Although there's, the trees have been ome up because of the amount of time. Still it's, you're dealing with kind ' of a related land area in terms of the slopes, etc. Okay. Having said that, I would feel that there should be a way of running that northern street to the property line and extending some kind of private drive to the south. I don't know. I think that possibly the south private drive , could be reviewcd to see if that could be eliminated. I didn't have an opportunity to review the grading plan before this evening and I guess I do have some concerns immediately as I ' look at this gra g plan. I think the, first of all I think that a conservation easement of 30 feet along the property boundary abutting''! Mancino's represents an excellent idea in trying to preserve those trees but you, the grading plan as indicated this evening grades right to the ' property line wide some severe slopes so I don't know how off the top of my head, I don't know how to remedy that or reconcile the situation with the conservation easement and the grading as shown. Obviously if they're going to grade right to the property line, that would , actually affect some of the trees that actually are on the Mancino property so that essentially is unacceptable. In the other portions of the subdivision I see that the developer is relatively conscientious of the trees that are bordering the wetland on the west part of the parcel and ' then even in the south. They've done a pretty good job of staying away from the wetland area so it's esser tially that difficult area near the southeast or southwest comer of the Mancino's that I think has to be reworked and I don't know if you change the grades here, I , 18 ' i t Planning Commission Meeting - August 17, 1994 don't know how that would change the street grades. Or what can be done there. If necessary, perhaps retaining walls represent an option. I don't know. The other thing that we normally have with these plats before we make decisions relates to the tree conservation and we generally have a tree inventory associated with these developments and although I can, I generally have the feeling that the trees along the western part of the development, adjacent to the wetland, I have a feeling that the grading doesn't go into those trees. I don't really know that. And again, along the east boundary I have concerns there too. There also is quite a bit of grading in Outlot A that doesn't appear to be necessary. And again, I don't know what trees are down in that area and how that's going to affect what could be done there in the future so I think that, I don't know, can they grade on Oudot A? If this is all platted together. Al -Jaff: Yes. Ledvina: Okay. So that would be something that I'd like to see also. Yeah, it appears they're grading quite a bit there. Well at any rate, I didn't have very much time to study that plan. Let's see. I guess as far as the street layout, it seems to be utilizing the area fairly well. I don't have a problem with that. Just for looking at some of the conditions of the staff report, there's some duplications in here I think. Number 8 is repeated as number 14. And then 25, 26, 19 is also repeated. Let's see. As it relates to number 9. Dave, I had a question on condition number 9. Talking about Lake Lucy Road. Would we also want to identify that those lots that are platted with, or that are developed with Oudot A shall be limited to interior streets or I guess do we have to define that at this time. Hempel: I don't believe we do. The other problem we have here is if Lake Lucy Road alignment does get shifted northerly, there is a potential lot site or two on the south side which may be appropriate so I guess at this stage we would have another chance at Outlot A. That would have to be platted and brought back before you to address that issue. Ledvina: Okay. So we would see Outlot A as a preliminary plat before us again, okay. Hempel: That's correct. Ledvina: Okay. I don't know what else I need to comment on here. I guess my overall feeling is that I'm a little uncomfortable. I am uncomfortable with the situation with the tree inventory. I would like to see the developer and the Mancino's try to work a little bit more on the access scenario because it appears that they're worlds apart. The developer does not want the private driveway and it appears that that's the preferred technique for development for the Mancino's and I don't know that we can get between that process and try to resolve that here tonight. And it's important because it really will affect how that area associated 19 Planning with the ravine associated tree Scott: Dave I the official alig between West clearance inbet comes right up talking about a With the chang property? It lc many feet or m going to lose, Meeting - August 17, 1994 developed and whether there's extensive grading in there or not and so I think we could see a little more work on this one. st, I have a question. Just a question. I noticed that the official, it looks like nent for Lake Lucy Road shows the road, and I'm talking about the area tptist Church and the Carlson property. It appears that there's quite a bit of °en the property to the south. When I look at the applicants drawing, it the property line. My question is, what kind of an impact, since we're oining properties, we really have not spoken about the Carlson property. in the alignment, what sort of impact is that going to have on the Carlson acs like the road, the applicant has shifted the road and I can't tell you how at it is. I mean it's obvious if the road goes straight through there, they're :)bably lose 2 lots. Hempel: I believe that roadway alignment for Lake Lucy Road has been established as a part of the feasibility study the city has conducted. Scott: On the a plicant's plan? Okay. Hempel: That's correct. My understanding. Ledvina: It loops a little different. Scott: Well it's a lot different. I mean I'm looking at this. Ledvina: Yeah. I The section just east of iHighway 41. In terms of the feasibility study and what the applicaInt is. Scott: Yeah I di)n't know, is this an official map here of the proposed Lake Lucy alignment? This is, okay. NL ell when I compare this to the alignment to the east, or the west side of the applicant's development, it touches the property line on the south side. So I'm trying to figure out if thin is official, it's not the same as what the applicant has on their property. Hempel: I belie extending out to south. There is was one option. Scott: Swing it ve in the feasibility study they showed 2 or 3 different alignments for the Westside Baptist Church directly affected the Carlson property to the a degraded wetland on that southwest corner of the Baptist Church site. That I think... elected to align!. up, yeah. r t 20 1 L 1 1 Planning Commission Meeting - August 17, 1994 Hempel: ...rejuvenate or restore that wetland... Scott: If you have a preliminary plat map you can, if you happen to have that, you can see how there's a difference between the road alignments and my question is, where is it going to be? Aanenson: I think the simple answer to that is, Mr. Engelhardt, Bill Engelhardt designed Lake Lucy project and he's also the project engineer for the Gestach - Paulson piece so we're confident that he matched the alignments. That would be our qualification on that and Mr. Carlson, as Dave indicated, is aware of this alignment that was approved by the City Council as part of the feasibility study. So they should match... Scott: Okay. Well I just was concerned because I saw some differences that were visible in these two. Aanenson: ...again, we put this in for your edification... Scott: Okay, that's fine. I don't have any other comments. Can I have a motion please? Ledvina: I would move that we table preliminary plat for Subdivision #94 -10 for Brenden Pond. Scott: Is there a second? Harberts: Second. Scott: It's been moved and seconded that we table this item. Is there any discussion? Ledvina moved, Harberts seconded that the Planning Commission table action on the preliminary plat for Subdivision #94 -10 for Brenden Pond. All voted in favor and the motion carried. (Nancy Mancino did not participate in voting on this item.) Scott: So we'll be seeing this, what on the 7th? Aanenson: If you give the staff direction? Scott: Okay, pretty easy. Matt is going to need the time and the rest of us are going to need the time to review the grading plan. We need a tree inventory. Aanenson: We have a tree inventory that was done. 21 Planning Commission Meeting - August 17, 1994 Scott: I mean a (graphic representation of where they are. I mean we went through this with Lake Susan Hill 9th Addition. We had a listing of all the trees but we had no idea where they were. Som�thing like that where we can see the locations and then also staff's best guess of the trees that are going to be removed due to streets, utilities and pads. Building pads. What did � miss? Harberts: I'd like a little further work, consideration with regard to the environmental resources here. With regard to full road versus perhaps that private drive concept and recognize that it's probably not the usual way that the city likes to conduct business but again I guess I'm just pointing out that I feel we have a unique situation here with regards to the environment and maybe just revisit it. Maybe the applicant, the Mancino's and city staff can sit down and maybe there's a resolution. ! It sounds like you're close. See if there's some alternative that i palatable for everyone. But I personally think there's some environmental issues here that a should be sensitive to: Thank you. Ledvina: Mr. Ciairman, also along that, the east property boundary and dealing with the grading in relation to the conservation easement. I think that has to be addressed somehow. And how that af'ects the grading for the entire parcel I don't know. Scott: Okay. Conrad: Just as � point of clarification. I know we can serve the two lots the Mancino's want to serve on the northwest with an extended cul -de -sac into their property. Dead ending into their property. I know we can. Well I'd like to know if that's possible. Same street standards as not a drive but the same street standards as we're using on the Brenden Pond roadway and them the question again is, how do we service the, can we service the two lots to the southwest d the Mancino property. ! Is there a feasible way of doing that and is that besides the priv4te drive that was recommended. Scott: Okay. Does that help? Aanenson: Y Scott: Well P Nutting: Part c which doesn't process and wl applicant and tl decision. That thank you. I'm sure we've got everything. glad you asked. We need that sometimes. the hypothetical here is you're talking about a plat for the Mancino property ist and may not ever exist and I think, I sense in thinking through this where staff is coming at this from is you know we may never get the Mancino's to agree you, know sitting down so then we're left with making a ecision either takes away a lot from the applicant or impacts the potential t 22 1 Planning Commission Meeting - August 17, 1994 development which the Mancino's may or may not do. As we say, they could sell the land. Someone else could come in and the northerly entrance may not be a significant issue. So what I struggle with in this whole thing is, we've got the applicant before us. We have to make the decision on how we're going to impact that on the basis of what might be impacted in the adjacent development. I'm not sure where we, you know the dividing line in terms of, I guess we're playing a little bit of, we're developing the Mancino property here with the street proposal that we're making. Harberts: But I think what we're also doing is. Nutting: Or we're moving towards that. Harberts: And I'm not disagreeing with you Ron. Nutting: I'm not on one side or the other. I'm throwing out the position here and I think we need to be a little careful as we, or it's very definitely it's a piece of property with a resources that for all of the ... this is the type of thing we want to be careful about and make sure that we preserve what we can from a development standpoint but I struggle with what we do with assuming they can't come to some agreement down the road as to accessing private drives or if staff doesn't feel there's any room to give on the private drive issue versus Option C that they're proposing. What direction we turn. Harberts: And I would just add or comment or take it from there on that perhaps what we're facing is perhaps a situation in which in the true sense of planning, after all the numbers are ran and all of this, it's like what does my gut tell me because this is really what we're doing is guiding land use. I think that's the real, one of the real elements here that we have to deal with. And there's nothing wrong with that ...but that's where my frustration or going back and revealing all of the things that we've done with other developments. The Lake Susan. The tree inventory. The conservation. All of those things. To me it looks like we have all of those elements here. Wait a minute. Maybe we need to just stop and revisit that. Understand what we're doing. Because of this site we don't have, I don't know if there's a whole of other sites like this but it's just a matter of taking a little extra time. Understanding what we're doing. Nutting: I agree. Scott: Good. Thank you for your comments. Thank you all for coming.
