PHYSICAL CHARACTER.: The site has a significant border of trees along the northern property line. In addition, a stand of significant trees is located in the northwest corner of the property. Additional trees are scattered around the farmstead. The high point of the site is 1004 feet located where the existing hous now stands. The site slopes downwards to the west, north and east from this point. A low point at elevation 970 is located in the northeast corner of the property. 2000 LAND USE PLAN: Residential - Low Density (Net Density Range 1.2 - 4.0 units per acre) CY 7 6200 - -- LAKE 6300 Y/RG/N /A 6400 ®__ — ASTER CIRCL 6500 W a� .6600 6800 6900 -e_ W a� E°- z Q _U � U 7100 —o LL O H H U U 7200 -- — 7300 J 7500--- 7600------ - 7 700 --_ 780o v ® O M M M CA O I LANE SST ✓OE,�� e �e LAKE j MINNEWASHTA COURT ��rr�.cllo- Q o } I U I I C r Oak Ridge of Minnewashta March 6, 1996 Page 2 PROPOSAUSUMN ARY The applicant is proposing a 23 lot subdivision on 11.8 acres. Access to the site will be provided through the connection of Country Oaks Road which currently terminates at the south and north property lines. The plans propose on extending and connecting Country Oaks Drive to the north and south. This will complete the dead -end street in the Country Oaks development to the north. The street connection will also provide continuity between neighborhoods and access to Minnewashta Park located north of Kings Road and west of Minnewashta Parkway. An existing 8 -foot wide bituminous trail has been extended along Country Oaks Drive from the north. A 5- foot wide concrete sidewalk is proposed along Country Oaks Drive from the south (Oaks of Minnewashta). The applicant should continue the extension of the 5 -foot wide concrete sidewalk along Country Oaks Drive and connect it to the existing 8 -foot wide bituminous trail at the north end of the project. The proposed subdivision is consistent with a sketch plan that staff reviewed as part of the platting of the Oaks of Minnewashta which was approved immediately to the south of this development. As proposed, this development will construct two storm water ponds for water quality and ' quantity purposes prior to discharging runoff from the site into Country Oaks. Storm sewers will convey most of the site's runoff via storm sewer pipes to the ponds for treatment. The outlet pipe for the pond will be revised and relocated outside the tree limits to minimize tree loss. Staff ' will also be working with the applicant's engineer in an effort to reduce site grading and the need for the westerly pond by means of adjusting street grades and /or house pads. ' Given the location of the existing home and site topography, construction of the streets and house pads will result in significant earth moving. Staff will be working with the project ' engineer to minimize the amount of grading and retain site characteristics. Staff has already looked at servicing Lots 2, 3, 4 and 5, Block 2 (Oak Ridge Court) through the use of a private street. Staff believes this will result in reducing the amount of grading by pulling the house pads ' away from the perimeter of the lot lines and allowing for relocation/enlargement of the storm water pond in the northeast corner of the site. Staff will be recommending that the applicant revise the preliminary plat drawings to incorporate staff s design using the private street scenario ' for Oak Ridge Court. Staff is recommending approval of the preliminary plat subject to the conditions contained in the ' staff report. Staff believes that through the use of a private street and the elimination of one of the storm ponds, if feasible, the amount of grading will be significantly reduced. F11 Oak Ridge of Minnewashta March 6, 1996 Page 3 BACKGROUND I In May 1993, the City approved an administrative subdivision clarifying the eastern property line of this property. An existing house, stable, and bam/shed are located in the western portion of the property. LANDSCAPING/TR PRESERVATION Existing canopy coverage for the proposed Oak Ridge development is approximately 13 percent, or 64,450 square feet. The applicant is removing approximately 16,600 square feet of canopy for construction and stormwater installation purposes leaving 47,850 square feet. Minimum coverage requirements for a low density residential with existing coverage less than 13 percent is 25 percent. The target canopy coverage for this site equals 128,474 square feet. Since the applicant does not meet minimum requirements, the forestation plantings required for the site total 59 trees. The 16,600 square feet of canopy area being removed is multiplied by 1.2 and is 'I calculated to be 18 trees for replacement. The total forestation and replacement plantings required are 77 trees. The applicant has currently proposed 42 trees for the site. Staff recommends the building pads for lots around the western cul -de -sac be pulled closer to the �) road in order to pull the houses away from the existing wooded area in the north western corner. By doing so, it would not be necessary to do any tree removal within that area. In addition, the a stormwater pipes along the northern property line can be relocated away from the tree line to preserve these trees. Any additional trees preserved on -site will reduce the amount of replacement plantings required on site. Trees that are to be preserved on -site shah be protected with tree protection fencing pursuant to city ordinance. WETLANDS I According to City maps it appears there are no wetlands on the site. However, there is a creek/ravine that intersects the west end of the plat through Lots 7 and 8, Block 1. The applicant should retain a qualified wetlands delineator to prepare a report or letter of clarification as to the status of the creek. Surface Water Management Plan The City has prepared and adopted a Surface Water Management Plan (SWMP) to serve as a tool to protect, preserve and enhance water resources. The plan identifies, from a regional perspective, the storm water quantity and quality improvements 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 a 1 Oak Ridge of Minnewashta March 6, 1996 Page 4 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 the 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. Storm Water Quali1y Fees The SWMP has established a connection charge for water quality systems. The cash dedication will 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 if the applicant constructs the pond or $4.00 per cubic yard for excavation of the pond if the City constructs the pond. Fees are reduced based on the costs of the developers contribution to the SWMP design parameters. The proposed SWMP quality charge has been calculated at $800 /acre for single family residential developments. This proposed development of 11.8 acres would then be responsible for a water quality connection charge of $9,440. Since the applicant is proposing to construct water quality basins in accordance with the City's SWMP, these fees will then be waived. Storm Water Quantity Fees The SWMP has established an connection charge 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. The connection charge is based on the type of land use for the area. Fees will be based on the total developable land. Undevelopable area (wetlands), public parks, and existing development is exempt from the fees. The fees are negotiable based on the developers contribution to the SWMP design parameters. Single family residential developments will have a connection charge of $1,980 per developable acre. This proposed single family residential development of 11.8 acres would then be responsible for a water quantity connection charge of $23,364. The City will apply credits to the applicant's surface water quantity fees for construction of improvements in accordance with SWMP which include such items as outlet control devices, trunk storm sewer pipes, pond oversizing, etc. The final connection charges will be determined after review of the final construction plans. DRAINAGE The site is divided into two drainage subdistricts with the westerly one - quarter of the site draining west into a creek/wetland located within the City of Victoria. This creek is a part of the Minnehaha Creek Watershed District and drains into Lake Virginia from the west. The easterly 'I Oak Ridge of Minnewashta March 6, 1996 'I Page 5 three- quarters of the site drains northerly towards Country Oaks development. A combination of storm sewers and overland sheet drainage conveys runoff from this site to a stormwater pond created in conjunction with the Country Oaks development. Unfortunately, back in 1989 the City only required on -site project for each individual project as it developed. Therefore, the pond in Country Oaks is not large enough to accommodate direct discharge of the storm water from this site without first ponding on -site to prevent flooding in Country Oaks. As proposed, this development will construct two storm water ponds for water quality and quantity purposes �I prior to discharging runoff from the site into Country Oaks. Storm sewers will convey most of the site's runoff via storm sewer pipes to the ponds for treatment. The outlet pipe for the pond will be revised and relocated outside the tree limits to minimize tree loss. The minimum easement width for all utilities located outside of the street right -of -way shall be 20 feet. Staff will also be working with the applicant's engineer in an effort to reduce site grading and the need for the westerly pond by means of adjusting street grades and/or house pads. I' Detailed storm calculations were submitted for the storm sewer system. Staff has found them generally acceptable. However, staff still needs to review the ponding calculations to determine " if the ponds are designed to meet Surface Water Management water quality requirements. The ponds are also being designed to maintain the predeveloped runoff rate from the site. The outlet pipe from the easterly pond will require an easement from the church property which is outside the plat. The City has existing drainage and utility easements over the rear yards of those lots in Country Oaks where the storm sewer is proposed to be extended. Staff and the applicant will be working with the neighboring property owners regarding timing of the project and restoration of their properties. In an effort to reduce sump pump discharge into the City's sanitary sewer system.,, staff will be requiring the applicant to extend drain tile behind the curbs for the homes to discharge into. The City will only require drain tile in those areas where the properties are not adjacent storm ponds, wetlands, or catch basins. GRADING The majority of the site is proposed to be graded for the storm water ponds, streets and house pads. The site slopes from south to north with an elevation change from 1002 to 972. A small (' row of trees exists along both north and south property lines. Staff and the applicant's engineer will be adjusting site grades slightly to preserve these buffer strips. However, some trees will be lost in the areas where the street, Country Oaks Drive, will be extended as well as the storm I' sewer to Country Oaks. Given the location of the existing home and site topography, construction of the streets and house pads will result in significant earth moving. Staff will be working with the project engineer to minimize the amount of grading and retain site characteristics. Staff laas already I ' Oak Ridge of Minnewashta March 6, 1996 ' Page 6 looked at servicing Lots 2, 3, 4 and 5, Block 2 (Oak Ridge Court) through the use of a private ' street. Staff believes this will result in reducing the amount of grading by pulling the house pads away from the perimeter of the lot lines and allowing for relocation/enlargement of the storm water pond in the northeast corner of the site. Staff will be recommending that the applicant ' revise the preliminary plat drawings to incorporate staff's design using the private street scenario for Oak Ridge Court. ' UTILITIES ' Municipal utility service is available to the site from the north and south. Sanitary sewer and water lines have been extended to the site within Country Oaks Drive. The proposed utility plan is fairly straightforward. Fire hydrant locations may be adjusted during the final construction J u plan review process. The applicant shall be responsible for installing municipal utilities to service this site. The utility system shall be designed and constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. Since the utilities and street system, except for Oak Ridge Court, will be owned and maintained by the City upon completion and acceptance, the applicant will be required to enter into a development contract with the City and provide a financial security in the form of a letter of credit to guarantee installation of the public improvements and conditions of final plat approval. The existing home site on Lot 12, Block 1 is currently on a well and septic system. As a result of this improvement, the house will be required to hook up to sanitary sewer within 30 days of the system becoming operational. The existing septic system shall be abandoned in accordance with City and Health Department codes. The existing home may utilize the well until the well fails, at which time the property owner must connect to City water. As a result of the site grading, the outbuildings on the parcel will be removed. The appropriate demolition permit should be obtained and complied with through the City's Building Department. STREETS The plans propose on extending and connecting Country Oaks Drive to the north and south. This will complete the dead -end street in the Country Oaks development to the north. The street connection will also provide continuity between neighborhoods and access to Minnewashta Park located north of Kings Road and west of Minnewashta Parkway. An existing 8 -foot wide bituminous trail has been extended along Country Oaks Drive from the north. A 5 -foot wide concrete sidewalk is proposed along Country Oaks Drive from the south (Oaks of Minnewashta). The applicant should continue the extension of the 5 -foot wide concrete sidewalk along Country Oaks Drive and connect it to the existing 8 -foot wide bituminous trail at the north end of the proj ect. Oak Ridge of Minnewashta March 6, 1996 Page 7 II Two cul -de -sac streets are proposed to serve the remaining portion of the site. The applicant will be dedicating the necessary street right -of -way with the final plat. Staff has had concerns regarding the pond locations and size and the amount of grading for Oak Ridge Court. Staff has redesigned this area of the development using a private street to serve up to four lots (Attachment 1). Using the private street reduces construction costs for the applicant, i.e. curb and gutters, reduced street width and site grading. It also gives more flexibility in the pond design/location. Staff is recommending that the applicant redesign Oak Ridge Court using a private street. �I During construction, access may have to be maintained to the existing residence on Lot 12. The driveway will be relocated as a part of the street construction project. The existing driveway for �I Lot 12 will be relocated to Oak Ridge Lane. Construction traffic to the site is also a concern. Access to the site is either from Country Oaks Drive to the north or Country Oaks Drive from the south. The southerly portion of Country Oaks Drive is still under construction and subject to a damage by construction traffic. Therefore, access to this site should be limited to Country Oaks Drive from the north unless Country Oaks Drive to the south is completed first. The street p p t3's standards (:31 feet wide ' s are proposed to be constructed in accordance to the City's back -to- back). The streets in the development will be owned and maintained by the City upon completion with the exception of Oak Ridge Court if the private street is implemented. With the private street, a cross - access and maintenance agreement will need to be prepared and recorded. EROSION CONTROL Erosion control fencing is proposed along the downstream perimeter of the site. Rock construction entrances should also be incorporated into the erosion control plans and maintained until the first lift of asphalt has been installed. Erosion control measures shall also be implemented around all catch basins until the site has been fully revegetated and the streets paved. PRIVATE STREET FINDINGS In order to permit private streets, the city must find that the following conditions exist: () prevailing P 1 The revailin development pattern makes it unfeasible or inappropriate to construct a public street. In making this determination, the city may consider the location of existing property lines and homes, local or geographic conditions and the existence of wetlands. I' (2) After reviewing the surrounding area, it is concluded that an extension of the public street system is not required to serve other parcels in the area, improve access, or to provide a street system consistent with the comprehensive plan. Oak Ridge of Minnewashta March 6, 1996 Page 8 (3) The use of the private street will permit enhanced protection of the city's natural resources ' including wetlands and forested areas. Finding: The proposed private street to serve lots at the eastern end of the ' development is not necessary to provide access to adjacent properties. Were a public street provided to access these lots, additional trees would need to be ' removed due to staff recommendation that the stormwater ponding in the northeast corner of the site, which is a natural low area, be enlarged to provide ponding for the entire site and eliminate the second pond. ' PARKS & RECREATION ' The Parks & Recreation Commission met on February 27, 1996 to review the proposed development. In lieu of land dedication, the Commission recommended the payment of full park and trail fees pursuant to City Ordinance. COMPLIANCE TABLE ' BLOCK LOT AREA (SQ. FT.) FRONTAGE (FT.) DEPTH (FT.)

Lack of adequate off -site public improvements or support systems. ' Finding The proposed subdivision is provided with adequate urban infrastructure. ' PLANNING COMMISSION UPDATE The Planning Commission held a public hearing on March 6, 1996 to review the proposed development. The Planning Commission voted unanimously to recommend approval of the preliminary plat with the modification of condition 16 adding the option of a public street instead of a private street and condition 19 adding that the city attorney verify that the city could collect additional assessments for the seven additional lots on the property in excess of what was previously estimated for the parcel. ' Staff has met with the applicant's engineer and it appears that a public street will work on the plat. Staff has attached the letters to Ms. Hallgren regarding the assessments for the Lake Minnewashta improvements wherein she was advised that additional unit charges would be collected for units in ' excess of the 16. In addition, staff has discussed the issue with the City Attorney who concurs with staff's condition. Oak Ridge of Minnewashta March 6, 1996 Page 11 RECOMMENDATION Staff recommends that the City Council adopt the following motion: "The City Council approves subdivision 96 -2, the Oak Ridge of Lake Minnewashta, prepared by Loucks & Associates, Inc., dated January 19, 1996, creating 23 lots and associated right -of -way subject to the following conditions: 1.

A review of the assessment roll information concerning your property has been made. The proposed assessment ' to be levied against your property is based on a total of 11.5 acres of land containing no wetlands. This assessment roll has implemented a 1.4 unit per net acreage assessment factor at a rate of $760 per unit. Based on these criteria, your property could generate at least 28 units ' upon development. Therefore, a $21,280 assessment is proposed against your property. If your property is subdivided in the future generating more than 28 units, the additional charges will then be collected. I should also note that your property is listed under green acre status for 1993. ' Under green acre status, any levied special assessments against this property would go deferred. If you should have any further questions or comments, please feel free to contact me.

The engineer informed me that the 28 unit determination was based on a concept plat which had been submitted to the City a few months back that included your property. Review of the latest preliminary plat or development in this area, however, no longer includes your property. Therefore, the proposed assessment against your property has been corrected to reflect the 1.4 unit per acre rate which is being implemented on nondeveloping large parcels. Attached please find the revised assessment notice in the amount of $12,160.00 based on 16 assessable units at $760.00 per unit. Please disregard my letter to you dated October 6, 1993 as it was based on incorrect information. This property is listed under green acre status for 1993, therefore, any levied special assessments against this property would go deferred until the green acre status is dropped and/or subdivision of the property occurs. I should also note that if subdivision of this property occurs in the future which generates more than 16 units, the additional unit charges would be collected as a part of the subdivision and development contract process. If you have any questions, please feel free to contact me Sincerely, c: Jean Meuwissen, Treasurer Bill Engelhardt, Engelhardt & Associates Allan Larson, Engelhardt & Associates fl October 8, 1993 CITY OF CHANHASSEN MINNESOTA SPECIAL ASSESSMENT NOTICE ' IMPROVEMENT NO: 90 -15 The City Council will hold a public hearing to consider proposed ' assessments for Improvement Project No. S.A.P No. 194 - 111 -01 on Monday, October 11 1993 at 7:30 p.m. in the Council Chambers at 690 Coulter Drive, Chanhassen, Minnesota. The area to be assessed includes Minnewashta Parkway, T.H. 5 to T.H. 7, Street, Storm Sewer and Walkway Improvements. The total amount of the proposed assessment is $ 402,800.00. Your assessment has been calculated in accordance with the City Council's policy as follows: ' Property Owner: Joann Hallgren Address: 6860 Minnewashta Parkway Excelsior, MN. 55331 I Parcel No: 25- 0060300 Proposed Assessment Against Your Property as Described Below: Specific Improvements Amount Street, Storm Sewer and Walkway Improvements '512,160.00 Assessment may be paid in full without interest or other charges ' within thirty (30) days after the assessment hearing date. These payments may be made in person or may be mailed to Chanhassen City Hall, 690 Coulter Drive, P.O. Box 147, Chanhassen, Minnesota 55317, Attention: Treasurer. Please indicate the parcel number on your check. Partial prepayment of the assessment is permitted. r If you elect not to pay the full amount within thirty (30) days after the hearing date, the assessment will be spread over 8 years with installments appearing on your real estate taxes beginning next year. Interest will be included at the rate of 7-1/2 percent of the unpaid balance. The proposed assessment roll is on file with the City Clerk. Written and oral objections to the proposed assessment by any property owner will be considered. No appeal may be taken as to the amount of any assessment adopted unless a written objection signed by the affected property owner is filed with the City Clerk prior to the assessment hearing or presented to the presiding officer at the hearing. Planning Commission Meeting - March 6, 1996 PUBLIC HEARING: PRELIMINARY PLAT APPROVAL TO SUBDIVIDE 11.8 ACRES INTO 23 SINGLE FAMILY LOTS LOCATED ON PROPERTY ZONED RSF RESIDENTIAL SINGLE ' FAMILY AND LOCATED WEST OF STRATFORD RIDGE AND NORTH OF THE OAKS OF MINNEWASHTA, OAK RIDGE OF MINNEWASHTA GREG HAHN Bob Generous presented the staff report on this item. ' Mancino: Any questions from commissioners at this time? Does the applicant wish to address the Planning Commission please? i u L Tom Walsh: Madam Chair, my name is Tom Walsh. I'm...planner for this proposal. Also with me this evening is the... Greg Hahn who is the proposer and Jeff... I just had a comment. Three of the items recommended in the staff report... Item number 2, that the building pads for the lot around the westerly cul -de -sac locate closer to the road in order to pull the houses away from the existing wooded area in the northwest. I just want to make sure that we had an understanding that we're not going to pull those pads so close that we cannot meet setback requirements so we're going to maintain the 30 foot front yard setback and we will build within the parameters. Most of the pad sites on the entire development are ... deep by approximately 80 feet wide. Really the proof of what's going to happen there depends on the type of house...rambler or walkout or look -out. Item number 16, it's in the form of a recommendation that the applicant shall revise the preliminary plat drawings to incorporate a private street versus a public street and we are proposing a public street that meets all of the ordinance requirements and perhaps this condition should be either scratched or modified so that it's clear that we don't have to do a private street for this development. And then item 19. The applicant shall be responsible for payment of deferred assessments for Minnewashta Parkway improvement including interest to date. In addition, the applicant shall be responsible for seven additional lots ... in the amount of $760.00 plus interest from October, 1993. We've been trying to figure out if this was a 429 with special assessment project. Nothing shows up on our records so I don't know if there was an assessment hearing and they're presently certified. We have no evidence of that 1983 action. Or 1993. And what I'd just like to suggest is perhaps having the City Attorney looking into it and get some information back to us as to what the particular status of those assessments are... assessments that were placed on the property... Other than that, we ... approve this proposal subject to the three issues that we proposed. Mancino: Thank you. Is there anyone else from your group that would like to present anything? Tom Walsh: We're tired. 26 Planning Commission Meeting o March 6, 1996 Mancino: But you're here. Okay. This is open for, this will be open for a public hearing as soon we get a motion and a second. Skubic moved, Meyer seconded to open the public hearing. Mancino: This is open for a public hearing. Those wishing to approach the Planning Commission on this issue, please do now. Mary Blue: Hello. My name is Mary Blue and I live at 6560 —Eden Prairie. `We just recently purchased a lot to the north of this development at 6770 Country Oaks Road and we looked at the plans and ... storm sewer that will be built onto our home? Mancino: Dave, do you want to? Hempel: Sure. Maybe Bob could put up the overhead there to show her the proposed storm sewer. Mancino: Mary, why don't you first show where your property is that you just purchased. Hempel: 7 or 6? Mary Blue: 6. Hempel: 6. That would be this one right here. Mary Blue: Right. And I guess just what my husband and I were worried about is that there is a berm that is on the back of our lot that was previously landscaped. It is overgrown right now and there is some natural land. Anyway, we just are worried or hoping that the integrity of our land will be as we have it ... We haven't started building our home but just hope that... Mancino: Sure. Dave can you talk about, will there be a disturbance back there and how much. Hempel: Certainly. The bottom shown in red on this drawing is a proposed storm sewer pipe from the proposed ponding area located back in here. The overflow and take the runoff, through the back yards of the proposed lots and right through the existing lots of Country Oaks. In this area here there was a drainage utility easement that ... on the property. Mancino: So right on Mary's property? 27 Planning Commission Meeting - March 6, 1996 ' Hempel: That's correct. That area's been excavated now and is overgrown with... wetland type vegetation. Cattails. Tall meadow grasses and so forth. And then the back side, I believe the church owns that. There's some vegetation and landscaping back through there. ' When the pipe is constructed will be about... disrupted back there, that property would be restored as it is today. As a part of the road construction, it would also be disrupting most of that lot as well so... F r r 77 Mancino: How much of it do you disturb or do they disturb when you go in and put the sewer? I mean are you talking about 20 feet? 40 feet? Hempel: It should be relatively shallow storm sewer pipe. Probably 25 foot wide area. I think the easement is like 40 feet wide so the ... would have to be contained within that easement area. The pipe will be buried so... Mancino: Will it change the ecosystem back there? Hempel: ...typically a lot of the homeowners will sod that area back there. This is at the very far end of the drainage area. Mostly likely it's up under some ... use it except for the wet spring and runoff periods of heavy rains. Mancino: Okay. But whatever is there now will be disturbed? Hempel: Right. Mancino: It won't be the same for a while. Mary Blue: And I understand that and then when you do dig in the ground, you do get a natural ... and then just where the landscaping currently is on the berm, there is rock. There are bushes. There's trees and stuff under there. And I don't know if the berm is going to be disturbed or not or if it is only in the depression that currently seems to be there. Mancino: Do they put the berm back Dave? If it's in that area and do they put the rock and the landscaping back the way it was? Hempel: The berm I believe that you're referring to is the back slope. This is the bottom of the ponding area in here. This would be sloping up towards the west, or towards the ... so that would look like a berm but that slope will be restored. The elevations and the vegetation... let you mow it or sod it. Mary Blue: We haven't decided exactly what we're going to do but that was... 28 Planning Commission Meeting - March 6, 1996 Mancino: Good. Do you have any other questions? Mary Blue: Not at this point, no. Mancino: Thank you. This is still an open public hearing. Anyone else wishing to address the Planning Commission. Seeing none, may I have a motion to close the public hearing please. Meyer moved, Peterson seconded to close the public healing. Mancino: Commissioners, comments. Craig. Peterson: I don't have a great deal of issues with it at all. It seems to be a relatively straight forward plan. The developers and the city staff seem to have agreed upon the points. The points brought up by the developer were just for clarification issues. They cart take care of those. No substantive comments. Mancino: Ladd, Conrad: Yeah, looks fine. Mancino: Mike, Meyer: Just maybe a question for Bob. Are you recommending that we delete number 16? Aanenson: Modify it. Generous: Well I was thinking more along the modification that he could add a phrase at the end of the sentence. Or verify that a public street works in conjunction with a storm, single storm water pond for the site. Mancino: Can you say that one more time? Generous: Or verify that a public street works in conjunction with a single storm water pond for the site. The only reason we even went to the private street is because we thought that they might have to enlarged the pond and we wanted to get separation between the house pads and the edge of the ponding areas. Meyer: That's all I have. 29 Planning Commission Meeting - March 6, 1996 ' Mancino: Bob. Skubic: I also have a question of staff regarding item number 19 that the applicant brought ' up. Is there a need to re -word that at all? Hempel: Sure. I can give you a little background on that one. Minnewashta Parkway was ' upgraded back in 1991 -92. The assessment hearing was in 1993. It was a 429 assessment project. There were numerous public hearings. I believe the initial assessment amount for that project per unit was close to $1,800.00 or $2,000.00 per unit. But through the public ' hearing process and neighborhood input and so forth, that per dollar unit was lowered quite a bit. The initial feasibility report went through and generated a preliminary assessment role based on how many units each parcel could ultimately be developed in. We were very ' conservative in that number. I think we figured two, two units or 1.7 units per acre and I think this plat here has 2.3 units per acre. So what typically happens, as each parcel's ' developed, we actually see how many parcels are able to develop on them, the additional amount of units created are then also charged the additional assessment for this Minnewashta Parkway improvement project. The city did use MSA funds, State Aid funds, local funds and a very small portion of it was assessed back so, we are attempting to recoup some of the investments the city has put forth into the project by further assessments. L Mancino: So there isn't any way until now that anyone would know this? That there were 7 additional lots until the preliminary plat came in. Hempel: That's correct. Mancino: So Mrs. Hallgren wouldn't have known. Hempel: We estimated 16 lots on this parcel deferred until development. One assessment was paid. The other 15 were Mancino: Okay, thank you. Hempel: City Council does have the authority to waive those additional fees, if they wish to appeal that additional 7 lots. Skubic: Thank you Dave. Mancino: Did you have a question at this time? 30 Planning Commission Meeting - March 6, 1996 Tom Walsh: Well Madam Chair, this really doesn't affect Mr. Hahn's purchase of the property but the previous property owner was not really happy with a $16,000.00 assessment. But the issue in question we need to have answered is can you, after the assessments have been certified, then the after the fact collect additional assessments in projects. That's not my understanding of the process and that's what ... City Attorney look at it. Because once you certified 16 lots or ... in the project, it's very difficult to add and subtract. The city's recouped... Mancino: I take it we've done this before. Hempel: Yes we have. IN Tom Walsh: ...all we want is some clarification. I' Hempel: We can certainly get that information. Mancino: Thank you. Jeff. II F°armakes: I have nothing further to add. Mancino: Don. I' Mehl: I have nothing either. Mancino: Okay. I just have two questions. Bob on 17. The applicant shall add a 5 foot I' wide concrete sidewalk along, is it the northern side of, or I mean the western side of Country Oaks Drive? Hempel: We haven't determined that yet. To the south of the subdivision there's a 5 foot concrete sidewalk going to extended along the west side of Country Oaks Drive. And the existing trail that's in the northern part of Country Oaks is on the eastern side so somewhere inbetween we've got to. Aanenson: Because the park's on the east side. Hempel: We'll work on that with the plan. I' Mancino: So that hasn't been determined yet, okay. I wondered where that side was not on here. The other question that came up from the applicant Bob was number 2. Pulling those I' building pads towards the road will still keep this within the setbacks? 31 I ' 11 L 1 L Planning Commission Meeting - March 6, 1996 Generous: Yes. He shows the building area that has just those little pads were pushed to the back of where they thought that they'd locate them so. Mancino: So we're able to save trees and still stay in the setback requirements? Okay, good. May I have a motion please? Peterson: I'll make a motion that the Planning Commission recommends approval of the Subdivision 496 -2, the Oak Ridge of Lake Minnewashta prepared by Loucks & Associates, Inc. dated January 19, 1996, creating 23 lots and associated right -of -way subject to the following conditions 1 through 33 and adding to number 16, or verify that a public, I can't read my writing. Imagine that. Verify that a public street works with a single storm water pond. Does that sound right? Generous: Yes. Mancino: Is there a second to the motion? Mehl: Second. Mancino: Any discussion? Friendly amendment to 19. Dave, how would you like us to word that as far as having a legal review? Hempel: Consulting the City Attorney to determine the legality of the additional assessments for Minnewashta Parkway. Mancino: Thank you. That will be added to number 19. Will you accept the friendly amendment? Peterson: Yes I do.

John Rask presented the staff report on this item. Mancino: Questions. Number 2 from the top. You're allowed to have 30 feet or 30% per structure, that means primary and secondary structure? Rask: Well you can have... Mancino: Or is it 30 feet for both? Rask: For both. Well what's showing here is, you'll notice it's not all clear. This would show if somebody was to build a boathouse. They could clear for that separate use, and that's allowed by ordinance now. Again it just wasn't, what we did was, if you create a view but you don't have to put your boathouse in there. You don't have to put your beach in that area, that you can work and clear vegetation in other areas as long as you basically adhere to the standards that are currently in place. Mancino: Can you clear for any other reasons? I mean what if it's not for view or you just want to go down and clear? 36
