The property is zoned A -2 and PUD. The average lot size is 17,642 square feet with a resulting gross density of 1.7 units per acre. The site is located south and west of Lake Susan Hills West and east of I Audubon Road and Bluff Creek Estates. Access to the subdivision will be provided by Osprey Lane off Audubon Road and Alisa Court. Osprey Lane will eventually connect with the existing Osprey Lane located within the Lake Susan Hills West 8th Addition. Currently, there is an I undeveloped parcel located to the east of the subject property and between the proposed Osprey Lane and the existing Osprey Lane, preventing this connection from taking place, however, the I applicant, staff, and the neighboring property owners (Mr. and Mrs. Goers) have had several meetings to discuss the road connection through their property among other issues. These meetings took place after the Planning Commission meeting and a consensus has been I reached on all the issues which will be discussed later on in detail. A cul-de -sac, Alisa Court, extends north and south from Osprey Lane to service all of the proposed lots with the exception of Lot 1, Block 2. 1 The southern portion of the Shenandoah Ridge site was located outside of the MUSA line until May, 1991, when the expansion was approved by the Metropolitan Council. The zoning map I shows the northern portion of the site was rezoned into PUD when the Lake Susan Hills application was approved. Staff could not find any records approving the rezoning on the Shenandoah Ridge site and we believe it was an error created during the preparation of the 1 zoning map that can be easily corrected. Proposed Lot 10, Block 1 has an existing residence and is surrounded by four accessory 1 structures. All structures are proposed to be removed with the exception of the single family Chaska Brick house. Presently, access to this residence is gained from Audubon Road via a private driveway. When Alisa Court is constructed, the existing residence will gain its access off of the cul -de -sac. The existing structure on the site meets the zoning ordinance setback requirements. 1 The site has approximately 176 trees located mainly on the east and south portion of the site. The plans indicate that some of those trees will be preserved. The applicant must use design I measures to preserve the trees. Trees proposed for removal will be replaced. A preservation easement over the area where tree concentrations exist, will be required. This easement will prevent any construction from taking place and subsequently preserving the trees. Since the I Planning Commission meeting, the grading plans have been changed and staff has a clearer picture of how the trees will be impacted. The plans indicate that the majority of the trees located to the rear of Lots 9, 11, and 12, Block 1, are now proposed to be saved. The same I is true for trees located along the south edge of Lot 3, Block 2 and Lot 4, Block 2. There is only the absolute minimal grading taking place in any of these locations, and therefore, they should be preserved. 1 1 1 Shenandoah Ridge August 4, 1993 Page 3 The Landscaping and Tree Preservation Ordinance states that all development located on arterial and collector streets are required to provide streetscape landscaping. The landscaping plan, which was submitted by the applicant as part of the preliminary plat is in response to this requirement. 1 However, staff is recommending a mixture of 10 additional deciduous and conifers trees be added along the westerly edge of the site. Staff believes that this plat request is a reasonable one and is generally consistent with guidelines established by the city's Comprehensive Plan and Zoning Ordinance. We find it to be well designed with only modest revisions being required. We are recommending that it be approved with conditions outlined in the report. REZONING 1 The applicant is proposing to rezone the property from A -2, Agricultural Estate to RSF, Residential Single Family. The area to the east and north is zoned Planned Unit Development. The area to the west of the site is zoned Residential Single Family and is zoned Agricultural Estate District to the south. 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 1.7 units per acre and 2.5 units per acre net after the streets are taken out. This area is in the MUSA area. Staff is recommending that this area be rezoned to RSF and the rezoning is consistent with the Comprehensive Plan. PRELIMINARY AND FINAL PLAT The applicant is proposing to subdivide an 11.5 acre site into 20 single family lots. The density of the proposed subdivision is 1.7 units per acre gross, and 2.5 units per acre net after removing the roads. All the lots meet or exceed the minimum 15,000 square feet of area, with an average lot size of 17,642 square feet. All of the proposed lots meet the minimum requirement of the Zoning Ordinance. Staff notes that the proposal is consistent with the Comprehensive Plan and generally consistent with the Zoning Ordinance. ACCESS 1 Access for this development is proposed via Osprey Lane and Alisa Court. Osprey Lane is accessed via Audubon Road. Alisa Court extends north and south from Osprey Lane. The southern end of Alisa Court will terminate with a temporary cul -de -sac. A temporary road easement will be required by the applicant for the temporary cul -de -sac which lies outside the dedicated right -of -way. - - = - - . _ - - - - - = - - - _ : = _ - - - 1 1 1 1 Shenandoah Ridge August 4, 1993 Page 4 - -- - -- - - .._ .. . - - - •• -- - - - - -- - - - Staff has been working with the applicant and the adjacent property owners to the east (Mr. and Mrs. Bill Goers) to have the necessary street right -of -way for Osprey Lane is dedicated, the City would construct next year an interim street section to provide continuity between the two subdivisions. If the necessary right -of -way is dedicated, the street would be constructed to the City's rural standards which consists of a 24 -foot wide asphalt surface 1 and 6 -foot gravel shoulders. Lot 1, Block 1 contains an existing Chaska brick home which has a driveway that extends over ' Lot 4, Block 1, and onto Audubon Road. This driveway should be removed and access to the existing house shall be provided via Alisa Court. All lots will be restricted to access off of Alisa Court with the exception of Lot 1, Block 2. This parcel may gain access off of Osprey Lane. GRADING & DRAINAGE The grading plan proposes grading the site for the road, storm drainage ponds and house pads. In addition, berms are proposed adjacent to Audubon Road. The site drains from west to east. ::•-: • _. - -- - .• . _.. Y • 1 enPleyed. I 1 1 Shenandoah Ridge August 4, 1993 Page 5 At the time of preliminary plat review, staff was concerned with the location and function 1 of a previous storm water retention pond proposed on Lots 11, 12 and 13, Block 1. Staff requested that the applicant work with the adjacent property owner to the east (Mr. & Mrs. Bill Goers) to look at relocating the storm water retention pond to the adjacent parcel where it fits in more naturally with the existing terrain. As a result, the applicant has had meetings with staff and the Goers to resolve the issue. Subsequent meetings have resulted I in a final relocation of the storm water retention pond south of future extension of Osprey Lane (see Attachment 1). This storm water pond is an interim pond until the Goers' property develops some time in the future. The Goers are essentially unable to develop the I property at this time due to the lack of sanitary sewer availability to the site. Revised final grading and drainage plans showing this new location should be submitted for staff review and approval. 1 Staff has indicated to the applicant and the Goers if the necessary street right -of -way for Osprey Lane is dedicated, the City would construct next year an interim street section .to 1 provide continuity between the two subdivisions. The street would be constructed to the City's rural standards which consists of a 24 -foot wide asphalt surface and 6-foot gravel shoulders. As a part of the negotiations, it appears the developer will be stockpiling 1. additional fill material to create the roadbed for Osprey Lane. The existing soil conditions on the Goers' property indicates there is topsoil material that should be removed prior to placement of the fill material. It only makes sense to have this organic material removed prior to placement of the roadbed material to ensure a stable foundation for the street surface. In addition, watermain and sanitary sewer lines will be constructed in the future 1 as well. The extension of Osprey Lane through the Goers' property will result in creating an earthen dam between the roadbed and the property to the north. The plans propose maintaining the drainage pattern through the parcel by installing a 12 -inch culvert underneath Osprey Lane to convey runoff from the north side of the road to the proposed - I retention pond. In the future when the Goers develop their parcel, additional fill material may be needed to fill the rear portions of the lots lying north of Osprey Lane and/or incorporate a storm sewer to connect to the proposed storm sewer to drain the northerly I portion of the property. If the property is filled, it may result in removal of some additional trees. Staff is comfortable with the current proposal since it gives some flexibility in the future for the property owner to adequately develop his property. 1 The storm water retention pond proposed south of the Osprey Lane has been designed to meet the City's water quality and quantity requirements. Calculations have been submitted 1 for staff review. Staff has reviewed the calculations and it appears the pond may need to be slightly larger to incorporate the entire plat of Shenandoah Ridge including the property lying north of Osprey Lane. Staff is confident that the storm sewer pond design can be 1 worked out at the staff level. Detailed construction plans and specifications have been 1 1 1 Shenandoah Ridge August 4, 1993 Page 6 submitted to staff for review and these changes will be incorporated accordingly. The proposed retention pond is proposed to be a dry pond as shown on the plans. Staff is requesting that the pond be redesigned to maintain a two -foot water elevation to improve water quality. Once the pond has been completed and accepted by the City, the City will take over perpetual ownership and maintenance responsibilities until the pond is relocated to a future downstream regional basin when the property develops. Another issue regarding grading was the proposed drainage pattern for Alisa Court lying ' south of Osprey Lane. Previously the plans proposed the drainage to go south into the adjacent property. The new grading plan has been revised to raise the street grade so the drainage runs back north where it is picked up by catch basins and conveyed to the storm water retention pond. Some grading still will be required along the southerly property line to facilitate the house pad location on Lot 3, Block 3. Due to wet soil conditions throughout the City, staff has implemented a policy to require draintile behind the curb throughout the entire subdivision. The drain tile system serves a two -fold purpose by assisting street subgrade drainage as well as giving the homeowners a place to discharge the in household sump pumps. Due to the lot configurations, draintile may not be necessary along the entire length of Osprey Lane. Exact location of the draintile system will be determined during the construction plan review stage. UTILITIES r Site is proposed to be serviced by municipal sewer and water from Audubon Road. The City has recently installed sanitary sewer and water lines adjacent to the development along the west side 1 of Audubon Road. Sewer is proposed to be extended underneath Audubon Road between Lots 5 and 6, Block 1. The applicant should be aware the City will not allow open cutting of Audubon Road and therefore the sewer line will have to be "jacked" underneath Audubon Road. The applicant is proposing a 6 -inch water line along Alisa Court to the south end of the plat for - future extension. Staff also recommends that the sanitary sewer by extended to the south line of the plat for future extension as well. ... _. a _.. _ _ . -. ... _ .

Staff has received detailed construction plans 1 1 1 Shenandoah Ridge August 4, 1993 Page 7 and specifications for the project. The applicant has modified the plans to reflect staff's conditions with regards to increasing the eight -inch water line along Osprey Lane. STREETS Access to the site is proposed from Audubon Road facing Valley Ridge Trail North. The As previously discussed, contingent upon dedication of the right -of -way and construction of the roadbed for Osprey Lane, the City will construct a temporary street section between Lake Susan Hills West 8th Addition and this subdivision proposal. The City will construct this with the 1994 street leveling and sealcoat program and at no cost to the property owner or developer. The developer will be responsible for removal of any organic or unsuitable material found prior to placement of roadbed material. The construction plans indicate a deceleration or right turn lane from Audubon Road into ' the development, however, no acceleration lane. Staff feels that this is a necessity and should be included with the street construction phase of the development. This condition is already stipulated in the original staff report and should remain. Street grades in the subdivision range from 1.82% to 10% which is in excess of the City ordinance. Staff feels however due to the topographic constraints such as the future roadway connection to the east, the 10% street grade is acceptable. • •. The applicant is proposing temporary cul-de -sac on Alisa PF P P g a P Court south of Osprey Lane. The appropriate temporary turnaround easements will be necessary for the portions of the turnaround that lies outside the dedicated right -of -way. Sta€€dees 1 •• . . _ ._ . Access to the lots shall be from the interior streets and not Audubon Road. The corner lots (Lots 1 and 13, Block 1, Lot 2, Block ' 2, and Lot 1, Block 3) shall access Alisa Court and not Osprey Lane. Staff recommends that the driveway access to Lot 1, Block 2 be towards the easterly side of the lot, furthest from the intersection of Audubon Road. 1 1 II Shenandoah Ridge August 4, 1993 Page 8 1 Similarly to the development to the west of the subdivision (Bluff Creek Estates 1st Addition), auxiliary turn lanes will be required for this development. A deceleration and acceleration lane I in accordance with MnDOT standards, shall be included with the street construction phase of the development. 1 MISCELLANEOUS The appropriate utility and drainage easements will be required over the plat for the extension 1 of sanitary and storm sewer lines. A minimum width of the easements shall be 20 -feet wide. In addition, the appropriate utility and drainage easements shall be dedicated to the city for the storm sewers and storm water retention pond. The utility and drainage easements should be wide 1 enough to accommodate access for maintenance vehicles (a minimum of 20 feet around the perimeter of the pond). 1 According to City ordinance, the existing house on Lot 10, Block 1 will be required to connect to the new sanitary sewer line within 12 months after such a connection becomes available. Connection to city water is not required until the well on the property fails. I Erosion control measures are being employed throughout the plat. Staff does recommend that the applicant include a construction rock entrance at all access points to the site. Depending on 1 timing, the City may also require that erosion control silt fence be installed approximately 10 feet behind the curb throughout the subdivision in an effort to minimize erosion during the home I construction process. This will also alleviate the builder from having to install individual erosion control measures on each lot during the winter months when weather conditions prohibits (frost). The Upper Bluff Creek Trunk Sewer and Water Improvement (Project No. 91 -17) assessments I will be pending on the property. The assessment will be based on the number of net accessible acreage for each parcel based on the number of residential equivalent units (REU) or lots for the planned use. The feasibility report (91 -17) proposed a net accessible acreage of 7.93 acres with I 14 REU's for the parcel. Plat proposes 20 lots which is six more than the feasibility report anticipated. The applicant should be aware that the feasibility report is only an estimate of the I minimum number of lots that could be developed on the parcel. The final assessment will actually be based on the actual number lots developed on the site. The pending assessment as stated in the feasibility report will be low by approximately $13,470.00. The revised pending 1 assessment based on the proposed development (20 lots) is $44,900.00. The street name, Alisa Court, lying south of Osprey Lane has not been revised to Alisa 1 Lane. Public Safety, as well as Engineering, requested this change and the plat should be modified accordingly. 1 The final plat reflects a remnant parcel being created adjacent to Lots 1 and 2, Block 3 (Outlot A). This outlot is a part of the negotiations between the developer and the Goers. 1 1 1 Shenandoah Ridge August 4, 1993 Page 9 In return for the Goers granting the necessary drainage and utility easement for the 1 retention pond and storm sewers outside the plat, the Goers will be conveyed Outlot A which they need in order to create enough lot frontage for future subdividing. 1 PARK AND RECREATION On Tuesday, July 27, 1993, the Park and Recreation Commission reviewed the Shenandoah Ridge I Addition. Attached is a copy of the staff report. Upon conclusion of their meeting, the Commission recommended the following: 1 Park It was recommended that land acquisition not be pursued in favor of park fees. Fees will be collected at the time of building permit application. 1 Trails It is recommended that as a consideration of approval of Shenandoah Ridge, the applicant shall construct the portion of the city's comprehensive trail system previously described 1 in this report. Specifically, from the southern curb of Heron Drive to the southern terminus of Lot 4, Block 2. This trail is to be 8 feet in width with bituminous surfacing per standard city specifications. In consideration for this construction, trail and park fees I will be reduced by an amount equal to the cost construction. Said costs to be determined by the applicant for presentation to the city with documentation for verification. Current park and trial fees are $600.00 and $200.00 per single family unit, respectively. 1 COMPLIANCE WITH ORDINANCE - RSF DISTRICT 1 Lot Lot Lot Home Area Width Depth Setback 1 Ordinance 15,000 90' 125' 30' front/rear 10' sides BLOCK 1 Lot 1 18,053 112.87 199.5' Lot 2 17,090 90' 197' 1 Lot 3 15,477 90' 170' 1 Lot 4 15,069 92' 147' 76' on curve 139.5' I Lot 5 15,604 7 o c 1 1 1 Shenandoah Ridge I August 4, 1993 Page 10 1 90' front setback Lot 6 32,843 221 146' 1 Lot 7 23,603 110.73cu1 -de -sac 169.5' 1 Lot 8 18,122 68.23' cul -de -sac 166.5' 105' front setback 1 Lot 9 17,983 85.87' cul -de -sac 139.5' 106' front setback 1 Lot 10 16,019 271' corner lot 131' 30F / 30F / 70S 70' 30 SIDE 1 Lot 11 15,139 94' 188' 1 Lot 12 16,535 90' 184' Lot 13 17,581 86' corner lot 150' I 197' BLOCK 2 I Lot 1 15,216 95' corner lot 147' 169' 1 Lot 2 15,232 110' corner lot 132' Lot 3 18,705 91' 216' 1 Lot 4 19,646 90' 218.5' 1 BLOCK 3 Lot 1 19,653 108' corner lot 213.5' 1 206' Lot 2 20,309 91' 227.5' I Lot 3 21,836 91' 241' 1 1 1 1 Shenandoah Ridge August 4, 1993 Page 11 TREE PRESERVATION 1 The tree and landscaping plan shows the vegetated areas and the amount of tree removal. The I site contains 176 trees along the east and south portions of the site that should be preserved as best possible. The wooded areas are on the steeper elevations of the site. Some of the vegetation is in locations where road extension will be required and will cause the loss of some of them. The applicant is proposing to replace those trees. Staff is recommending an additional mixture of 10 deciduous and conifers to be located along the westerly edge of the site. A preservation easement over the area where tree concentrations exist, will be required. This easement will prevent any construction from taking place and subsequently preserving the trees. Due to revisions in the grading plans, a larger number of trees will be preserved. Staff is I recommending the following trees be included within the tree preservation list and protected by a preservation easement. Trees number 1, 5 through 8,10,16,17, 21, 22, 25 through 32, 36, 39 through 63, 73, 74, 78, 79, 81 through 84, 86, and 108 through 110. LANDSCAPING , The Landscaping and Tree Preservation requirements state that a landscape buffer is required I when a subdivision 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 identifies plant material locations along Audubon Road as well as a single planting 1 within each front yard. Appropriate financial security will be required. The applicant is proposing to add 37 deciduous and conifers trees along the westerly edge 1 of the site. Staff is recommending a mixture of 10 additional deciduous and conifers trees be added along the westerly edge of the site. ill PLANNING COMMISSION ACTION The Planning Commission reviewed this item at their August 4, 1993, meeting. They generally 1 concurred with staff's recommendations but issues were raised by commissioners and by several residents resulting in some conditions being modified. I Condition #8 was modified to ensure that it was clear that only the south end of Alisa Court will have a temporary cul -de -sac. As is normally the case, this temporary cul-de -sac will be barricaded ' and equipped with a sign indicating that the road will be extended in the future. Staff is recommending that this condition be further modified to read, "All lots located on the Alisa Court temporary cul -de -sac should have a notice placed in the chain of title indicating that their street I is intended to be extended in the future and may ultimately not be a dead end. The condition 1 1 1 1 Shenandoah Ridge August 4, 1993 Page 12 1 should be further modified to indicate that the street name of the south portion of Alisa Court should be modified to indicate that it will potentially be a through street in the future. Thus, the name Alisa Lane or some other acceptable name should be required. Staff is recommending that the area south of Osprey Lane be called Alisa Lane. ' The commission discussed when the existing home on Lot 10, Block 1 should be required to connect to municipal sanitary sewer. Staff had originally recommended mandating hooking up within 12 months after the connection becomes available and whenever the well fails for city ' water connection. The Planning Commission believed that both connections should be made as immediate as possible and changed the connections to both sewer and water are required within 30 days after they become available to the site. 1 Three new conditions were added by the Planning Commission. The first, Condition #23, asked city staff to evaluate the potential for relocating a storm water pond as it exists on the plan to the adjacent parcel to the east. At the time of writing, staff is in the process of investigating this potential and expects to have this matter clarified before final plat. Condition #24 requires That a conservation easement be placed on a series of lots to protect existing trees. The applicant is further required to submit a new landscape plan showing all trees that will be removed as well as a replacement plan for these trees. Condition #25 suggests that if Alisa Court (Lane) becomes a permanent cul -de -sac, to make sure the city has appropriate easements in place. It is staff's view that this condition can be eliminated. The temporary easements that are taken remain in force until the street is extended in the future. If this extension never occurs, the temporary easements become de facto permanent. Thus, this condition can be eliminated. Staff is 1 recommending that a new condition #25 be added to address a non - related matter. The City Building Official has requested that a plan be submitted with standard city designations for dwelling types for each lot. This condition can be satisfied at the final plat stage. The applicant is seeking to expedite approval and is requesting a combined preliminary and final plat approval. Approval of the development contract is also on this agenda. The final plat is consistent with the preliminary plat and several of the earlier conditions have been resolved. The tree removal/preservation and landscaping plans have been submitted. There are some minor revisions that staff noted earlier in the report. Housing type designations and floor elevations are not shown as required by the City Building Official. Plans shall be revised to reflect this condition. 1 Staff is generally satisfied with the recommendations of the Planning Commission and is recommending that the item be approved as amended by the Commission except as noted above. 1 1 1 1 1 Shenandoah Ridge August 4, 1993 Page 13 RECOMMENDATION 1 REZONING Staff recommends the City Council adopt the following motion: I h' P g "The City Council approves Rezoning #93-4 for property zoned A -2 to RSF for Shenandoah 1 Ridge, subject to the following conditions: 1. The applicant shall enter into a development contract containing all of the conditions of I approval for this project and shall submit all required financial guarantees. The development contract shall be recorded against the property. 2. The applicant shall meet all conditions of the Subdivision #93 -14." PRELIMINARY AND FINAL PLAT 1 Staff recommends the City Council adopt the following motion: "The City Council approves the preliminary and final plat for Subdivision #93 -14 for Shenandoah Ridge Addition as shown on the plans dated July 6, 1993, subject to the following conditions: I 1. The developer shall dedicate the utilities within the right -of -way for permanent ownership. 2. The applicant shall pay full park fees at the time of building permit application. The 1 applicant shall construct the portion of the city's comprehensive trail system previously described in this report. Specifically, from the southern curb of Heron Drive to the I southern terminus of Lot 4, Block 2. This trail is to be 8 feet in width with bituminous surfacing per standard city specifications. In consideration for this construction, trail and park fees will be reduced by an amount equal to the cost construction. Said costs to be I determined by the applicant for presentation to the city with documentation for verification. Current park and trial fees are $600.00 and $200.00 per single family unit, respectively. 3. All areas disturbed during site grading shall be immediately restored with seed and disc- I mulched or wood fiber blanket within two weeks of completing site grading unless the city's (BMPH) planting dates dictate otherwise. All areas disturbed with slopes of 3:1 or 1 greater shall be restored with sod or seed and wood fiber blanket. 4. The vegetated areas which will not be affected by the development will be protected by a conservation easement. The conservation easement shall permit pruning, removal of dead or diseased vegetation and underbrush. All healthy trees over 6" caliper at 4' height shall not be permitted to be removed. The applicant shall provide the legal description for 1 1 1 Shenandoah Ridge August 4, 1993 Page 14 the easement. A conservation easement shall be placed on the following lots: Block 1, Lots 9, 10, 11, 12, 13; Block 2, Lot 4, and Block 3, Lots 1, 2, and 3. Staff is recommending the following trees be included within the tree preservation list and 1 protected by the preservation easement. Trees number 1, 5 through 8, 10, 16, 17, 21, 22, 25 through 32, 36, 39 through 63, 73, 1 74, 78, 79, 81 through 84, 86, and 108 through 110. 5. The existing wells is no longer in use and all sewage treatment systems shall be properly abandoned and furnish proof of abandonment to the Inspections Division. A city permit is required for on site sewage treatment system abandonment. This should be done pFief concurrently with site grading. ' 6. The applicant must obtain city demolition permits from the Inspections Division for PP n' Pe P� ' structures that will be removed (prior to removal). 7. The address for the existing home on Lot 10 shall be changed to Alisa Court. 8. The south end of Alisa Court shall have a temporary cul -de -sac. This cul -de -sac shall be barricaded with a sign indicating that the road will be extended in the future. All lots shall be notified in the chain of title that the street is a temporary cul -de -sac and will be ' extended in the future. Alisa Court, south of Osprey Lane, shall be renamed Alisa Lane which is consistent with its ultimate extension. 9. All street and utility improvements shall be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. Street construction plans shall also ' include a draintile system behind the curbs to accommodate household sump pump discharge. Detailed construction plans and specifications for utility and street improvements shall be submitted to the City for review and approval prior to final platting. Final construction plans and specifications are subject to City Council approval. 10. The applicant shall submit revised detailed storm drainage and ponding calculations to ' verify pipe sizing and pond volumes.

BOX 147 • CHANHASSEN, MINNESOTA 55317 1 (612) 937 -1900 • FAX (612) 937 -5739 MEMORANDUM TO: Sharmin Al -Jaff, Planner I 1 FROM: Dave Hempel, Assistant City Engineer `(k - 1 DATE: September 8, 1993 SUBJ: Review of Final Plat for Shenandoah Ridge 1 Project No. 93 -20 1 Upon review of the final plat prepared by John Oliver & Associates, stamped August 23, 1993, I offer the following comments and recommendations: 1 GRADING & DRAINAGE At the time of relimin �'YP plat review, staff was concerned with the location and function of a P previous storm water retention pond proposed on lots 11, 12 and 13, Block 1. Staff requested that the applicant work with the adjacent property owner to the east (Mr. & Mrs. Bill Goers) to 1 look at relocating the storm water retention pond to the adjacent parcel where it fit more naturally with the existing terrain. As a result, the applicant has had meetings with staff and the Goers to resolve the issue. Subsequent meetings have resulted in a final relocation of the storm water retention pond south of future extension of Osprey Lane (see Attachment 1). This storm water pond is an interim pond until the Goers property develops some time in the future. The Goers are essentially unable to develop the property at this time due to the lack of sanitary sewer availability to the site. Revised final grading and drainage plans showing this new location should be submitted for staff review and approval. Staff has indicated to the applicant and the Goers if the necessary street right -of -way for Osprey Lane is dedicated the City would construct next year an interim street section to provide continuity between the two subdivisions. The street would be constructed to the City's rural standards which consists of a 24 -foot wide asphalt surface and 6 -foot gravel shoulders. As a part of the negotiations, it appears the developer will be stockpiling additional fill material to create the roadbed for Osprey Lane. The existing soil conditions on the Goers property indicates there is topsoil material that should be removed prior to placement of the fill material. It only makes sense to have this organic material removed prior to placement of the roadbed material to ensure 1 1 1 1 I Sharmin Al -Jaff September 8, 1993 Page 2 1 a stable foundation for the street surface. In addition, watermain and sanitary sewer lines will I be constructed in the future as well. The extension of Osprey Lane through the Goers property will result in creating an earthen dam I between the roadbed and the property to the north. The plans propose on maintaining the drainage pattern through the parcel by installing a 12 -inch culvert underneath Osprey Lane to convey runoff from the north side of the road to the proposed retention pond. In the future when I the Goers develop their parcel, additional fill material may be needed to fill the rear portions of the lots lying north of Osprey Lane and/or incorporate a storm sewer to connect to the proposed storm sewer to drain the northerly portion of the property. If the property is filled, it may result 1 in removal of some additional trees. Staff is comfortable with the current proposal since it gives some flexibility in the future for the property owner to adequately develop his property. I The storm water retention pond proposed south of the Osprey Lane has been designed to meet the City's water quality and quantity requirements. Calculations have been submitted for staff review. Staff has reviewed the calculations and it appears the pond may need to be slightly 1 larger to incorporate the entire plat of Shenandoah Ridge including the property lying north of Osprey Lane. Staff is confident that the storm sewer pond design can be worked out at the staff level. Detailed construction plans and specifications have been submitted to staff for review and I these changes will be incorporated accordingly. The proposed retention pond is proposed to be a dry pond as shown on the plans. Staff is requesting that the pond be redesigned to maintain I a two -foot water elevation to improve water quality. Once the pond has been completed and accepted by the City, the City will take over perpetual ownership and maintenance responsibilities until the pond is relocated to a future downstream regional basin when the property develops. 1 Another issue regarding grading was the proposed drainage pattern for Alisa Court lying south of Osprey Lane. Previously the plans proposed the drainage to go south into the adjacent I property. The new grading plan has been revised to raise the street grade so the drainage runs back north where it is picked up by catch basins and conveyed to the storm water retention pond. Some grading still will be required along the southerly property line to facilitate the house pad 1 location on Lot 3, Block 3. UTILITIES Staff has received detailed construction plans and specifications for the project. The applicant has modified the plans to reflect staffs' conditions with regards to increasing the eight -inch water 1 line along Osprey Lane. STREETS I As previously discussed, contingent upon dedication of the right -of -way and construction of the 1 1 1 Sharmin Al -Jaff September 8, 1993 Page 3 1 roadbed for Osprey Lane, the City will construct a temporary street section between Lake Susan Hills West 8th Addition and this subdivision proposal. The City will construct this with the 1994 I street leveling and sealcoat program and at no cost to the property owner or developer. The developer will be responsible for removal of any organic or unsuitable material found prior to placement of roadbed material. 1 The construction plans indicate a deceleration or right turn lane from Audubon Road into the development, however, no acceleration lane. Staff feels that this is a necessity and should be III included with the street construction phase of the development. This condition is already stipulated in the original staff report and should remain. MIS CELLANEOUS 1 The street name, Alisa Court, lying south of Osprey Lane has not been revised to Alisa Lane. 1 Public Safety as well as Engineering requested this change and the plat should be modified accordingly. I The final plat reflects a remnant parcel being created adjacent to Lots 1 and 2, Block 3 (Outlot A). This outlot is a part of the negotiations between the developer and the Goers. In return for the Goers granting the necessary drainage and utility easement for the retention pond and storm sewers outside the plat, the Goers will be conveyed Outlot A which they need in order to create enough lot frontage for future subdividing. I RECOMMENDED CONDITIONS OF APPROVAL In addition to the conditions denoted previously in the staff report, the following should be I included or modified on the original staff report: 1. The necessary drainage and utility easements for all storm sewers and pond 1 retention/detention areas outside the platted right -of -way shall be conveyed to the City. 2. The applicant shall supply City staff with revised storm water and ponding calculations and revised grading and drainage plans for review and approval. 3. Final PP lat approval shall be contingent upon the applicant working with the adjacent I P property owner (Goers) in acquiring the necessary drainage and utility easements for construction of the storm sewer system and temporary retention pond lying outside the I plat. 4. The applicant shall be responsible for excavating any topsoil material prior to placement 1 of the roadbed material for the construction of Osprey Lane through the Goers property. 1 1 I Sharmin Al -Jaff September 8, 1993 Page 4 1 In addition, the applicant shall be responsible for construction of the storm sewer from 1 Shenandoah Ridge to the proposed retention pond. 5. Contingent upon dedication of the right -of -way for the extension of Osprey Lane through I the Goers property and the applicant construction the roadbed to subgrade, the City will construct at no cost to the applicant or Goers an interim street section to connect Lake Susan Hills West 8th Addition to Shenandoah Ridge.

A copy of the staff report presented to the commissioners is attached. Upon concluding their discussion that evening, the commissioners approved the following recommendation: Park It was recommended that land acquisition not be pursued in favor of park fees. Fees will be collected at the time of building permit application. Trails It is recommended that as a consideration of approval of Shenandoah Ridge, the applicant shall construct the portion of the city's comprehensive trail system previously described in this report. Specifically, from the southern curb of Heron Drive to the southern terminus of Lot 4, Block 2. This trail is to be 8 feet in width with bituminous surfacing per standard city specifications. In consideration for this construction, trail and park fees will be reduced by an amount equal to the cost construction. Said costs to be determined by the applicant for presentation to the city with documentation for verification. Current park and trial fees are $600,00 and $200.00 per single family unit, respectively. 1 1 1 1 1 t 0, PRINTED ON RECYCLED PAPER 1 PRC DATE: 7/27/93 CITY OF CC DATE: CIIANUADE k HOFFMAN:k I STAFF REPORT PROPOSAL: Rezoning of 11.5 acres of property zoned PUD and A2 to RSF and Preliminary Plat to subdivide 11.5 acres into 20 single family lots, Shenandoah Ridge 1 Z LOCATION: South of Heron Drive, East of Audubon Road (see vicinity map) . •Q V J 0 APPLICANT: Shamrock Development John Oliver and Associates 3200 Main Street, Suite 300 580 Dodge Avenue Coon Rapids, MN 55433 Elk River, MN 55338 PRESENT ZONING: PUD, Planned Unit Development and A2, Agricultural Estate District ' ADJACENT ZONING I AND LAND USE: N - PUD -R, Planned Unit Development S - A2, Agricultural Estate Q E - PUD -R and A2 I W - Audubon Road L ail COMPREHENSIVE PLAN: W I-- This site is located in close proximity to Power Hill Park and Sunset Ridge Park.

Public Present: Name Address I/ Craig Mertz 8561 Osprey Lane Bill & Vicky Goers 1601 Lyman Blvd. Lynn Caswell 580 Dodge, Elk River Doug Barinsky 8731 Audubon Road Sharmin Al -Jaff presented the staff report on this item. Vice Chair Conrail called the public hearing to order. Conrad: Is the applicant here? Would the applicant like to make any I statements? Are you familiar with the staff report? Agree with their recommendations? Lynn Caswell: Yes. Lynn Caswell with John Alden and Associates. I've read the staff report. Conrad: Okay, good. It's a public hearing. We'll open it up for public 1/ comments. Are there any? Craig Mertz: I'm Craig Mertz, 8561 Osprey Lane. I live about 300 feet , east of the barn on this property. I've looked at the staff report and the proposed preliminary plat... Conrad: Okay, thanks Craig. Any other comments? Doug Barinsky: My name is Doug Barinsky. I live at 8731 Audubon. I have ll the property that lies directly south of this. I just have two questions. Is that street that's coming to the south end there, is that a cul -de -sac or what's there? Al -Jaff: To be extended in the future. 1 11 11 Planning Commission Meeting August 4, 1993 - Page 2 Doug Barinsky: What if that isn't compatible with how I want to develop my property? Because there's also a street coming out of Bluff Creek right now right here which would come into my property. Hempel: Mr. Chairman, maybe I can address that further. Mr. Barinsky has been in to see the City Engineer a few times with regard to the sewer service to the property and so forth. As a part of platting adjacent properties, we're somewhat obligated to look for future roadway extensions to tie the parcels together. It's kind of a puzzle if you will to put the pieces together. Ultimately we do like to try and eliminate or reduce the amount of access points onto a collector type street. This situation though Mr. Barinsky did bring up a valid point. There is already a new intersection created directly across from his parcel so potentially if Mr. Barinsky doesn't use that access to his property, I guess it would probably become more of a permanent type solution but I guess we would encourage to see it connect to the south. And maybe eliminate that other access out onto Audubon Road depending how your parcels lays out I guess. We'd like to keep that option open for you should you require it in the future. Once we give it up, we'll never be able to get another access so we're essentially giving you two options to service your property. Doug Barinsky: Alright. Rather than make a cul -de -sac out of it at this point then, it would just be a deadend street at this point. Hempel: With a temporary cul -de -sac established, yes. Doug Barinsky: Second question I have is, is that property line there has a total line of mature trees and I'm wondering what this development plan calls for in terms of tree protection and I haven't had any survey work done so I don't know who's side of the property line the trees are on but I think they're probably right on the property line. I guess I'd like to know what the developer does have planned there at this point. It bothers me a little bit because I came home from work one night last week and on Bluff Creek, right across the road, they had free cleared a huge stand of mature trees to make room for part of their development and I'd hate to come home from work some night and find out that this developer has free cleared those trees when they could be quite valuable to the homeowners that are going to have the lots adjacent to it on both sides of that property. So could anyone comment on that? And does a development like this call for a tree plan in terms of what's already on that property as far as mature trees. Al -Jaff: The trees that are located to the south. Doug Barinsky: There's mature trees entirely along, yeah that property line there. Al -Jaff: Correct. They are all on this property. Where the road is. Doug Barinsky: It's been surveyed and determined they're all on that property? Al -Jaff: Correct. 1 Planning Commission Meeting I/ August 4, 1993 - Page 3 Doug Barinsky: Okay. What is the plan for those trees? Al -Jaff: Okay, the area where the road is going to go through, those tree will have. Doug Barinsky: At this point there's no reason for a road to go through though because that's not being developed beyond there. Why would one cut" down trees when there's no. Hempel: The trees are being cleared to facilitate a turning radius at the end of that street for fire trucks, garbage trucks and so forth. The home pads, the trees will obviously be removed for those. The road right -of- way. That's about the extent of it. The lot, or the trees along the side ll lot lines and rear yards are proposed to be left as they are today. Doug Barinsky: In this process does the developer submit that, that those trees will be left and is that part of the approval process that the city II has to approve control of mature trees on a piece of property like that? Hempel: I think Sharmin can address this a little bit more with the conservation easement. Is that what's proposed? Al -Jaff: We are requiring a conservation easement. We're also requiring that additional trees be planted on the site. Doug Barinsky: At this point my concern is just the mature trees. Whatever you require for new planting. 1 Al -Jaff: Some of them are going to go with the grading. • Doug Barinsky: Well can you tell me what is going? Is the developer goin to free clear that because it will be easier for him to go in and move dir or what's the plans? Al -Jaff: On the south is going to be mainly preserved with the exception I/ of this area right here. Hempel: The house pads. I/ Al -Jaff: Exactly, the house pads. Are you concerned with the southern I/ portion? Doug Barinsky: I'm concerned that somebody's going to come in there when this starts with a bulldozer and just clear those trees out because it's II going to be easier for them to work without those trees. Al -Jaff: They can't do that. , Doug Barinsky: What assurance can I have of that that that's not going to happen? R1 Jaf f: We will have snow fences around it. We will have a conservation" easement recorded against it. Before they do any type of grading, the snow fences have to be showing them where they may grade and where they cannot." 11 II Planning Commission Meeting August 4, 1993 - Page 4 II Doug Barinsky: The trees are more valuable there for the benefit of selling lots around there eventually and that's why I'm concerned about the II trees. If the developer would like to comment, I'm glad to hear what they've got to say about it. Lynn Caswell: The developer in this instance is, as most developers are 11 aware that if you have a tree on the lot, the lot is more valuable. One of the situations in here is we certainly, in order to get the utilities extended to the south line as staff has requested, we have to cut trees in II here. In order to, we can probably on this side of the lot, we leave all of these trees alone. But when somebody comes in there and builds their home, they're certainly going to have to clear the pads to build the house. il Have to clear a certain distance away from the foundations. Doug Barinsky: Those trees are on the property line so it's not very likely they'd build a house on the property line. I Lynn Caswell: This is a little bit deceiving in that we aren't showing any trees south of the property line. We're only locating the significant I trees on our site because those are the only ones...impact so there may be trees to the south. Doug Barinsky: I think there are, yeah. 11 Lynn Caswell: In this particular lot, because there's kind of a ravine that goes through here...grade a house pad in here...trees as we possibly II can on the entire site because trees enhances the value of the development... I Doug Barinsky: Well, as a more specific question. Is there an actual plan that has identified what will happen to those trees? Has this already been. II Conrad: Yeah, there really is. Doug Barinsky: I don't want to tie up your time tonight. If I could see il that. Scott: You can have all of ours. II Conrad: Yeah, but it's a good question. We're making light of it but it does detail what's. II Farmakes: It is something that we're increasing reviewing. Doug Barinsky: I assume the city is or you wouldn't have hired a full time II forester. Farmakes: But the trees on the property line, as you can see here, are shown for the actual property that's being developed. Not for your 11 property. They're sited and listed as to the size and nature of the tree. Doug Barinsky: Okay. Alright, that's all the questions I have really. Is II the protection of the adjoining properties. 11 Planning Commission Meeting II August 4, 1993 - Page 5 Conrad: The concern, you know the trees are listed that are going down or" that are there. They're inventoried. I'm trying to think if there's a bottom line conclusion after what you've talked about. You know we're concerned about the trees. It looks like we're going to replace those thail are taken down. Some big ones are going to go down as they make the cul -de -sac a temporary cul -de -sac. Not a whole lot but they are going to go down. I don't know if there's a better way to conclude it. 1 Mancino: Is there custom grading or anything? Farmakes: I think that that particular layout to access that property... 1 the way that the tree line parallels the property. At some point to access that property you have to eliminate those trees. Mancino: Those trees. I'm just thinking about the housepads. If we can do some custome grading on those two lots to further reduce. Aanenson: Yeah, I was just going to say. In that condition number 4 that" talks about the, that Sharmin has in here that talks about the tree preservation. You might want to add a home placement plan so we can look 11 at that and site the home such that it minimizes the tree loss. Lynn Caswell: I guess I'd just like to add that we will work with city staff the preserve the number of trees lost. IF Doug Barinsky: Well that would be a great improvement over what's going on at Bluff Creek so. 1 Lynn Caswell: This particular developer does his own grading... Doug Barinsky: Alright. I assume I can maybe have you show me sometime o0 the survey where your property line is there or where you think it is. Tha might help answer some of my questions. Lynn Caswell: As we continue on in the process, we can stake those out. II Doug Barinsky: Thank you. 1 Conrad: Thank you. Other comments. Bill Goers: Hi. My name is Bill Goers and I own the property to the east" and to the south of that and I'm mostly concerned about access to that, also for future development. Have not talked to the developer. We talked to staff very briefly. We'd just like to get some assurances that whatevell final puzzle that we put had together, that we've got access to some of ou property because we would not have access from Lyman Blvd the way the properties are currently situated so we'll need to get access from either 11 Arboretum or through the streets that are put in there. So we'd like to have the possibility to work with staff and the developer before anything li is finalized. Just for everyone's future ease of grief. Conrad: Thanks. Anything else? Any other comments? Is there a motion til close the public hearing? 1 1 11 Planning Commission Meeting August 4, 1993 - Page 6 II Mancino moved, Scott seconded to close the public hearing. All voted in favor and the motion carried. The public hearing was closed. II Conrad: Jeff, comments. Farmakes: I have no additional comments other than what we've just j discussed here. It seems to me to be a logical development the way it's laid out for this small of property. II Mancino: I have a couple of questions. Sharmin, I noticed that you stated in the staff report, on page 2, that the trees that will be removed will be replaced. As I look at the landscape plan here, I see that there's going to be tree removal in the street area and obviously for the house pads and 11 for the retention pond that will go in on the east side of Lots 11, 12 and 13. Correct? Does the developer, when they remove all these trees, do they get us another plan, will they give you, staff, another plan to show I where all those replaced trees will go on the development? Because they're not taking the place of the one tree per lot. They're not taking the place of the streetscape, landscaping on Audubon. So these are going to be over I and above that, correct? Al -Jaff: Actually when I calculated the landscaping, I included those trees that were along Audubon and the one located within the front yard. Mancino: Within the front yards. So if we take the combination of what we see on our landscape that parallels Audubon and the one tree per lot, that II total is the total of trees that will be removed? Al -Jaff: Correct. And we're adding an additional 10 trees along Audubon. 11 Mancino: Along Audubon. Did we also take into account the trees that will be taken out with the Alisa Court at that south end? Al -Jaff: No. Mancino: Okay. Then what I'd like to do is just make sure that those that are removed will be replaced and we have the right count and that we.know where they will be going. On a plan so that you do that with a developer. A few other questions that I have. I think Dave, I have a question on the recommendations. On recommendation number 5 about the existing wells and II sewage treatment systems to be abandoned. It seems to be in conflict with 15 as far as timing. II Hempel: Yes. That's correct. We should probably rephrase, I suggest condition number 5. The two conditions, one was from engineering and one was the building department. Just to cover the bases. The wells we were I talking about is the existing farm well which I assume is next to the existing farm house which is located on Lot 10, Block 1. Should that well be outside of the property lines, the new property lines of Lot 10, then it would have to be abandoned per State Codes. If the well is located within I Lot 10, it meets setbacks and is functioning properly, we will allow them to remain hooked up to that. Until the well fails. II II Planning Commission Meeting August 4, 1993 - Page 7 Mancino: And what about the sewage? I mean isn't it 12 months on one of it them you have, let's see. The sanitary sewer on Lot 10, Block 1 has to hook up within 12 months. The other existing ones need to be abandoned right away? Hempel: In this situation here, the septic site will probably have to be abandoned right away due to the conflicts with the other adjacent lots thall are being created. And I question the integrity of the system right now anyway so it's most likely, it'd probably be more appropriate to have the existing house be hooked up to the city sewer within 30 days upon being available. Mancino: So how do we want to combine those two? What would you think would be the best? Hempel: The existing wells outside of Lot 10. Any existing wells outside of Lot 10 shall be properly abandoned. And sewage treatment. 1 Mancino: Okay. Also under recommendation number 8, I would like to add the words at the beginning. The south end of Alisa Court shall have a temporary cul -de -sac because the north end will not be temporary. And thell on recommendation number 22. Where access to the lot shall be from the interior streets, not Audubon Road. The corner lot, which you have in parens, were missing one corner lot and I would like to add that in to sayll we have Lots 1 and 2, Block 1; Lot 1, Block 3. Also, Lot 2, Block 2. And that's it. Conrad: Good. Thanks Nancy. Good comments. Joe. 1 Scott: Dave, on I think it's Block 1, Lots 11, 12 and 13. Where the pond is going to be. You'll have to help me out with this. It falls away aboull I think from the middle of the lot it falls away about 30 feet or 20 feet or something. Could you, and maybe Sharmin I'd like to see how that sits in there because it seems like it's going to be fairly steep. It has to b� kind of kidney shaped, elongated, something that's running with the north/ south property line. Hempel: Right. it will essentially be benched into the side of the hill II because it's not quite at the toe of the slope so it will be benched or terraced in similar to like a house pad would be. Sharmin, do you have. Scott: That will have the proper slopes? I just for some reason putting II it in there struck me as being perhaps the slope would be too steep on the outside. It might be hazardous but if that's not the case. Hempel: The grades on the backyard are actually a 5:1 slope which are relatively flat compared to some other subdivisions recently subdivided where we have a 3:1 backyard slope which is fairly steep. Scott: Okay. I don't have any further questions. Conrad: Matt. 11 1 1 Planning Commission Meeting August 4, 1993 - Page 8 Ledvina: Just to take off on that comment. It seems like we're removing trees to build a pond. We certainly want to provide the surface water ponding and that treatment but I guess I was wondering, this small parcel that would be landlocked by the subdivision and the extension of Osprey Lane from the existing subdivision to the new subdivision. Is that a buildable area? Hempel: Currently it's not able to be serviced by city sewer. Sewer to this parcel would be extended from Lyman Blvd which is quite a ways to the south. Water would be available. Ledvina: So sewer is not available? So does that mean it's not a buildable lot in it's existing conditions? 1 Hempel: That's correct, yes. Ledvina: Well I guess, you know and I realize that we have to deal within r the limits of the property that we're working with but it would seem to be a reasonable thing to try to save those trees, to locate the pond further to the east in an unbuildable area. And I mean that seems practical. Do you have any comments on that? Hempel: Yes. Ideally, it would be a much better location and even could be considered interim storm pond until sewer's brought up to this area and this parcel actually develops where storm sewer's then could be retrofitted in the street to take the drainage runoff in this area into like a trunk storm sewer system and extended further on to the southeast. Into more of a regional ponding area through surface water management plan. There's really no indication of a regional pond in this area but given the characteristics down there, I'm sure there's some likelihood that one could be. Ledvina: So that area then represents an opportunity for a larger scale 11 pond to be constructed for storm water in this whole area? Hempel: To take care of, yes. A couple of neighborhoods essentially, yes. Ledvina: Has that been investigated at all with the different landowners in the vicinity? Hempel: It's something that I would like to pursue with the landowners and the developer on, definitely. Ledvina: Okay. Well I don't know if, I really would like to see that done. I'm definitely going to add it as a condition or would like to add that as a condition number 23. That the City staff pursue the relocation of that storm water pond further to the east on the adjacent parcel. I don't know if that condition represents a situation where you'd want to hold up this application but does the neighboring property owner have any thoughts on that? Bill Goers: I haven't given it any thought...? 1 1 Planning Commission Meeting August 4, 1993 - Page 9 Ledvina: Okay. What do you think about that small area that would be essentially on the north side of Osprey Lane? Do you feel that would be a buildable area? Vicky Goers: Well, since this week we've talked with Dave and Sharmin at 11 the office and we were at that time told it was not unbuildable, as I'm hearing now, so I'd like to pursue this with the staff. I don't even know" how much land we're talking about... Ledvina: Yeah, I understand and I'm not trying to resolve anything here but I'm interested in knowing whether there's a willingness to try to evaluate this. And if there is. Hempel: Commission member Ledvina. If I could just clarify as far as the il buildability of this lot. I did have conversations earlier this week with the Goers on it and in it's present state right now it is not a buildable lot without city sewer or water there. But eventually when city sewer is available and extended up to this point, yes. This area would be a buildable lot. Ledvina: Okay...and bring that housepad up but that adds quite a bit to the expense of that area and it looks like...At any rate, I would like to see that investigated further. That's all I had. Conrad: Thanks Matt. Diane. 1 Harberts: Well I'm really fuzzy on the access, with traffic. I'm not ver comfortable at all. I think the whole idea in terms of trying to manage growth is being able to plan for it as well. There's some issues with Osprey Lane. Do we make a requirement that the developer needs to work a deal with the owner in order to get that access. What if they can't come 11 to terms? Where does this sit? You know we've got some access questions by the owner to, I think this is south. Yeah, to the south of it. There's certainly some questions in terms of how much access is onto Audubon Road." And it's going to happen. I guess I would be inclined to have a better understanding. Maybe take a step back and look at the entire picture here. We always try to deal with the issue of bringing these pices of puzzle in here with regards to the road system and I think we've got a big puzzle II right here. So I would really encourage some kind of resolution of the access points, both with Osprey Lane. The parcel to the south. Because of the issues the owner raised. But then also in terms of, well given the II fact that we've got some future development that's coming here. I'm not very comfortable with the access points right now. I think if this is recommended to go forward, we probably want to also...that conservation language to easement. One other question I have for Dave. Did I understand on the south end of Alisa Lane, that there's going to be like a turnaround for the public... Shouldn't that be shown on the map or the site plans here to get an idea? Aren't they supposed to be put in right now or do II they have to wait until after the road gets punched through, if it gets punched through? Hempel: The temporary cul -de -sac will be constructed with the utility and1 street improvements. The overall, the preliminary plat does not reflect the additional street right -of -way necessary for it because it would be a , 1 J Planning Commission Meeting August 4, 1993 - Page 10 temporary roadway easement over those lots. One of the sheets here, the utility plan does show a temporary turnaround exceeding outside of the right -of -way limits. 11 Harberts: So is that going to impact with, I mean this is in the area of the trees with the size of the lots or with the housepads, with the grading that needs to occur. Hempel: Some of the grading for the street will necessitate removal of some of the trees. Also as those Lots 3, Block 3 and Lot 4, Block 2 are built on, the driveway and utility extension into the home will also take a couple of additional trees out of it. So the combination of it, with the turnaround. One way or another the trees would be lost due to. Harberts: I guess my comments really center around the fact that I'm not real clear on the access...figured out and maybe we should maybe take a 11 step back and look at this area because we do have other development coming in. That's my comments. Conrad: Thanks Diane. 11 Ledvina: I have a question. For Sharmin. On condition, or recommendation number 12. It says the applicant shall pursue acquiring the necessary easements for the extension of Osprey Lane between Shenandoah Ridge and Lake Susan Hills West 8th Addition. Can we require them to obtain the necessary easements? I mean can we strengthen that language? I mean is 11 that going to put a kink in their plan totally or maybe you or Dave could comment on that. Hempel: To be honest, that was my condition. I'm not sure whether or not i1 we can require them as part of this platting because they do have access from another improved public street. It comes to the issue, I hate to bring it up here again but the Nez Perce roadway extension. We're hoping, 11 in this situation here to work with the property owners. They seem to be in favor of the project. They're in favor of seeing the roadway go through. I think we can work out and negotiate seeing this road connect up to two subdivisions at this time. Ledvina: It doesn't require them to obtain those easements as a part of this to prevent that situation from potentially occurring? Hempel: That's true, yes. Ledvina: Okay. I guess I would be in favor of that. If it's the staff recommendation that that Osprey Lane go through, then I feel that's the way we should handle it. Aanenson: Make it a condition? We can't make it a condition that they buy somebody else's property to get access. Conrad: We don't have control of that. Aanenson: We don't have control over it. 1 1 Planning Commission Meeting August 4, 1993 - Page 11 Ledvina: But if they have these configurations to the streets. It Aanenson: What Dave is saying is the fact that we've laid it out as a staff and we see when that property comes in, we've already stated how we II see it being connected and that's why we've been working with them to see how it's going to be connected. Al -Jaff: It's our preference that it happens now before those 20 parcels II develop. But I don't think legally we can require them. Scott: Well we're going to see, if and when the other parcel comes up, we're going to see that and that would be a condition that we would place on that preliminary plat of the parcel in question. That the street needs to be connected for the development to go forward so I think, that's probably the best time to address it. Harberts: ...subdivision and roadway the way you want? 1 Aanenson: No. No, no, no. Scott: In this case though. 1 Harberts: ...take plans for it. Aanenson: No, that's what Dave did. We laid this out. This whole area II' out when this subdivision came in. I think that's what Dave eluded to. We've laid this whole subdivision how we feel it best accesses and that's why Dave is saying that road to the south, that the other gentleman was speaking about, that may not need to go through but this whole area has been laid out as we see how it can be accessed. Harberts: It has been laid out? Aanenson: Yes. , Hempel: This parcel was, the one before you this evening was laid out with staff and there was some previous concept plans in by other potential developers. And we felt this was the only way it could really develop. This way we're providing access to adjacent parcels to the south. We're providing access to the Goers parcel which we hope to connect shortly and I think that can strongly go forward and also I think the developer would be II in favor of also negotiating for a ponding easement out there. Even an interim one that would reduce his cost of ponding on site and be more of a permanent situation. Harberts: Mr. Chair, I have a question here. So are you feeling comfortable then that staff, that the access issues raised by one of the property owners, and some of the concerns raised by myself, that they have II been addressed? Hempel: Yes, I feel they have been adequately addressed. 1 Bill Goers: I'd like to make a comment about the existing access that there is on Osprey Lane is a temporary one right now? It is not permanent Planning Commission Meeting August 4, 1993 - Page 12 11 access that this original developer and I had agreed upon and they have not resolved that issue with me regarding that access. That only complicates ...and I'm not trying to do that but realistically that is an open issue still. Because that was not final access in an agreement that he and I had agreed upon. The one that he's using right now that he's calling a temporary one, calling a permanent one should be a temporary access in lieu of another one being built at a later time further south. And I've got the 1 docmentation on that... Hempel: Are you referring to Joe Miller's development to the east? 1 Bill Goers: Yes. Hempel: Okay. The existing Osprey Lane that currently dead ends to the east of your property is the one that Mr. Goers' referring to. I'm unaware of any type of. Mancino: It's paved isn't it? Hempel: Yes. It is paved. There's no homes taking access off of that. That was purely for the future extension basically back out to Audubon Road at some point. And also service this parcel with the street access. Bill Goers: He does have permanent deed to that property. He's just got a temporary deed, and again the original agreement... Hempel: The property's pretty well developed. Aanenson: And there's no other access points and it didn't show up on the title when we did development contract. That seems. 11 Conrad: It'd be real smart for you to be talking to Dave. You've got to make yourself comfortable. It looks like, in my mind it looks kind of tight. Where the roads are going and I think before this gets to City Council, you're going to want to express a firm opinion. My only question Dave is on one point and that's the Alisa Court. By chance, if that becomes a permanent cul -de -sac, we probably wouldn't, what easements do we need if that does? You know it changes in character a little bit and have we, you know I don't know what the odds are. I'm not sure what the developer to the south wants to do and our position to require it. I don't know what our standards are off of, well I'm just not sure. Other access points into his property. But I guess my question is, if this turns into permanent, I don't want it designed as temporary. So do we have the right easements to make, or the right leverage to make it permanent and make the developer more accountable to it as a permanent cul -de -sac? And that takes me to, you probably design it. If the developer thought it was going to be permanent, he might do a little bit different design. We don't know. 11 That's something we can't control but I do want to know that we can control it in the future if it does become permanent. Hempel: I believe we can. The thing that would be effected would be the setbacks of these lots so if it did become a permanent cul -de -sac, you would probably have a 20 foot front yard versus the 30 foot. 1 1 Planning Commission Meeting August 4, 1993 - Page 13 Conrad: When the property scheme became developed, would we have the right! to give it a turning radius down there? Would we be able to give it the right? Hempel: When the parcel to the south? Conrad: Well there's two properties on the property line to the south. When they came in for, when they were being developed, would we be able to II have the right amount of easements for a turnaround? A radius that would, whatever it is. A 60 foot radius or whatever it is. Hempel: We could require that at the time of preliminary plat. If the applicant did not wish to have that road extended through his parcel, yes. We could require that permanent cul -de -sac to be on the parcel to the south. Mr. Barinsky's parcel. Conrad: What do we do right now? 1 Hempel: Well, right now I guess I would still propose to leave it as shown. Leave the options open. This case the road could proceed. If we dead end it now and make it a permanent cul -de -sac, there's no way that road will go through. Conrad: Yeah, I don't want to do that. 1 Hempel: So in the future we have another option. Conrad: Okay. That's my only question. And the only other comment was toll make sure Dave that you can work with the applicants to the east. Or not the applicants, but the landowners and I'm sure you will. But I guess it's sort of up to you to be coming in and talking. Anything else? 1 Harberts: Matt just noted that the cul -de -sac is 600 feet. Ledvina: The way I measured it. 1 Conrad: That's the limit right? Harberts: Does the cul -de- sac... Ledvina: Barely. 1 Hempel: Right, it's approximately 600 feet in length but I think given the existing Chaska brick house that's situated there, it probably warrants a variance or something to the cul -de -sac length. Conrad: Okay, who wants the power? Who wants the motion? Harberts: I will. Now we're doing a subdivision and a rezoning? I'm going to do the rezoning first. I recommend that the Planning Commission adopt, or excuse me. Adopt the staff motion for rezoning according to Case" No. 93 -4 dated 8/4/93 for the Shenandoah Ridge Addition. And the motion then would be as stated in the report found on page 11. And I further recommend that the Planning Commission approve Case No. 93 -. I Planning Commission Meeting August 4, 1993 - Page 14 Conrad: Why don't we do it one at a time. Let's just do one at a time because there may be more debate on the second one. Harberts: Oh, there's quite a bit. Conrad: Yeah, is there a second to the rezoning motion? Mancino: I second. Conrad: Is there any discussion? Harberts moved, Mancino seconded that the Planning Commission recommends approval of Rezoning #93 -4 for property zoned A -2 to RSF for Shenandoah Ridge, subject to the following conditions: 1. The applicant 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 applicant shall meet all conditions of the Subdivision #93 - 14. All voted in favor and the motion carried unanimously. 11 Conrad: Is there a motion for the subdivision? Harberts: I did my duty. Well, I wrote everything down so I'll do it again. I recommend that the Planning Commission, let's see here, adopt for Case No. 93 -14, preliminary plat to subdivide 11.5 acres into 20 single family lots, Shenandoah Ridge Addition. Approve recommendations as outlined in the staff report with the change to number 8. Stipulate that the south end of Alisa Court shall have a temporary cul -de -sac. That the language in number 15 state that any existing house outside of Lot 10. Is there any additional language? 11 Hempel: Maybe if I can run one by here and see how it works. The existing house on Lot 10, Block 1 shall connect to municipal sanitary sewer and water service within 30 days after becoming available to the site. Conrad: Nice wording Diane. Harberts: And that item number 22. That the correction with regard to what lot shall be included, as Nancy pointed out. Scott: Lot 2, Block 2? Harberts: Yes. And item number 23 with regard to the regional pond. Number 24 to include a conservation easement be included as a condition. And number 24, with the discussion that centered around if this shall become a permanent cul -de -sac, to make sure that we have the appropriate easements in place to cover it. And also make sure what the impact is on the lot. That's it. Ledvina: I'll second that motion. r Planning Commission Meeting August 4, 1993 - Page 15 Conrad: Is there any discussion? 1 Scott: I have just one item, and it probably would be considered a friendly amendment that we want to have the pad locations on the final plat" so we can see exactly where the houses are and what sort of impact that's going to have on the trees as well. I think that was something that we had discussed. Mancino: Yeah, I kind of wrote it as, if I could add to that. That the applicant shall submit a landscape plan that shows all trees that are being removed are being replaced by new trees. Some sort of a new landscape plan. Conrad: Is that a new condition Nancy? 1 Mancino: Yeah. An amendment. Scott: On that conservation easement, do you want. Conrad: Is that an acceptable amendment? Harberts: Yep. 1 Scott: Do we want to name the lots that the conservation easement should be on or is that broad language regarding conservation easements enough to get the result that we're looking for? Aanenson: It's Block 2, Lot 3 and 4 isn't it? 1 Al -Jaff: You could name it. Scott: Well I'm thinking Block 1, Lots 9, 10, 11, 12, 13. Block 2, Lot 4 Block 3, Lots 1, 2 and 3. Conrad: Who seconded the motion? 1 Mancino: Matt. Conrad: Was Nancy's amendment acceptable to you? 1 Ledvina: Yes. I would also add, I don't mean to complicate this but I would like to clarify condition number 23...regarding the pond. I would II like to see the staff evaluate the potential for relocating the storm water pond as it exists on the plan, to the adjacent parcel to the east. Conrad: Isn't that what you meant Diane? Harberts: Well yeah. When we talked about, because Dave had made the I/ comment about it becoming a regional pond. Conrad: But I'm glad you added that. Ledvina: It's just to say that they'll focus their efforts in that area. There may be a possibility for a regional pond in other areas but I want J Planning Commission Meeting August 4, 1993 - Page 16 that specific area to be evaluated for that purpose. 1 Conrad: Anything else? Harberts moved, Ledvina seconded that the Planning Commission recommend 11 approval of Subdivision #93 -14 for Shenandoah Ridge Addition as shown on the plans dated July 6, 1993, subject to the following conditions: 1. The developer shall dedicate the utilities within the right -of -way for permanent ownership. 2. The applicant shall pay full park fees at the time of building permit application.
