HomeMy WebLinkAbout9B - Glynwater PP STAFF AGENDA REPORT DATE: ge JANE KANSIER, PLANNING COORDINATOR DONALD RYE, PLANNING DIRECTOR CONSIDER APPROVAL OF ORDINANCE #98-XX APPROVING A ZONE CHANGE FROM THE A-1 (AGRICULTURAL) DISTRICT AND THE C-1 (CONSERVATION) DISTRICT TO THE R-2 (URBAN RESIDENTIAL) DISTRICT, RESOLUTION 98-XX APPROVING THE CONDITIONAL USE PERMIT FOR 121 TOWNHOUSE UNITS AND RESOLUTION 98-XX APPROVING THE PRELIMINARY PLAT FOR "GL YNWATER" MARCH 16, 1998 AGENDA #: PREPARED BY: REVIEWED BY: SUBJECT: INTRODUCTION: The purpose of this agenda item is to consider approval of a plan for 121 townhouse units located on the south side of CSAH 82, directly south of the entrance to The Wilds and just west of Fremont Avenue. The proposal consists of three separate actions, These are the adoption of Ordinance 98-XX approving a zone change from the A-1 (Agricultural) District and the C-1 (Conservation) District to the R-2 (Urban Residential) District, adoption of Resolution 98-XX approving the Conditional Use Permit for the townhouse development, and adoption of Resolution #98- XX approving the preliminary plat for to be known as Glynwater, The proposed townhouse development consists of 121 units on 32.12 buildable acres, for a density of 3.7 units per acre. The preliminary plat consists of 109 lots for the individual townhouses and the common area, Not all of the units are located on individual lots. There are six 4- unit condominium buildings located on 6 lots. The preliminary plat also includes 11,91 acres of parkland, Attached to this report is a copy of the Planning Report which provides more details about this development. BACKGROUND: In December, 1997, the applicant filed an application for a 1:\98files\98subdiv\preplat\gJynwate\glyncc.doc Page 1 16200 Eagle Creek Ave. S.E., Prior LaKe, Minnesota 55372-1714 / Ph. (612) 447-4230 / Fax (61;q447-4245 AN EQUAL OPPORTUNITY EMPLOYER Schematic Planned Unit Development for a townhouse development on this property. On January 5, 1998, the City Council denied this application based on the fact the proposed Schematic PUD Plan was inconsistent with the stated purposes and intent of the PUD section of the Zoning Ordinance in that the same proposal, with the exception of the private streets, could be accomplished through the Conditional Use Permit Process. The Developer then filed the$~ applications to develop the property. ~ DISCUSSION: The Planning Commission held a public hearing to review this request on February 23, 1998, Attached to this report is a copy of the draft minutes to the Planning Commission meeting. At the hearing, the Commission heard testimony from the Developer of this project. The Developer explained that this plan is very similar to the proposed PUD plan. The major differences are the public instead of private roads and the access to Fremont Avenue. The Developer also addressed the issue of disturbance of steep slopes on the site. He noted there are 5.33 acres, or 12.6% of the site, that include slopes 20% or greater. Of this area, 1.64 acres, or 4% of the entire site, are disturbed. There was no other public testimony at this hearing. Planning Commission Recommendation: The Planning Commission recommended approval of the Zone Change request based on the fact the area is located within the MUSA and the R-2 district is consistent with the Comprehensive Plan Land Use Map designation, The Planning Commission also recommended approval of the Conditional Use Permit subject to the following conditions: 1. Six identification signs will be permitted on the site. The signage plan must be revised to identify the locations of these signs, and to clarify the location of each type of sign. If a sign is located adjacent to the park access on the east side of Glynwater Trail, no portion of the sign or fence is permitted in the parkland. 2. The plan must provide a calculation showing the impervious surface, not including road right-of-way, on the portion of the site located within the Shoreland District. The impervious surface of the site in the Shoreland District may not exceed 30% of the site I :\98files\98subdiv\preplat\glynwate\glyncc.doc Page 2 area, less right-of-way. 3. The plan must identify Phase I and Phase /I of the development. The plan must also note that Phase II will not be allowed to develop until the property is included within the MUSA, and services can be extended. 4. A letter of credit for the landscaping and tree replacement must be submitted prior to approval of the final plat documents. 5, The homeowner's association documents must be revised to include the correct legal descriptions for each association within the development. These documents must be recorded with the final plat documents. 6. A new set of plans, showing all of the revisions, must be submitted prior to final approval of the conditional use permit. Finally, the Planning Commission recommended approval of the Preliminary Plat to be known as "Glynwater", subject to the following conditions: 1. Change the name of Bayview Drive. There is already a Bayview Circle in the City street system. In addition, change the name of Spring Glen Road or Spring Glen Circle so there is only one Spring Glen. 2. Outlot B must be identified as Outlot A. 3. Provide the following information on the Engineering Plans: a) Show all utilities in the profile view. b) Show size of all existing utilities in the area. c) Include insulation detail to be used on sanitary sewer. d) Provide calculations showing that the pavement section is adequate (see plate #501 in the Public Works Design Manual). e) Street grades within 100 feet of intersections cannot exceed 2.00 percent. f) Provide design and profiles for the median and the street improvements to Fremont. The City may be willing to share in the engineering costs for this design as per the City oversizing policy. g) Show the construction limits on the grading plans. The grading and installation of the sanitary sewer 1:\98files\98subdiv\preplat\glynwate\glyncc.doc Page 3 will impact the 20% slopes. h) Indicate on the plan areas where slopes are greater than 5: 1. i) The wetland report indicates a wetland "water course" flowing south from basin B to basin A. A road and grading is proposed over this water course. The wetland report must be revised to address the impact of this filling and grading on the water course. j) NURP ponds shall have 6: 1 slopes below the NWL, and 4: 1 slopes above the NWL. k) Show the grading detail for the Rambler Walkout. There is a 10' grade difference for Lots 1-6, Block 1. o Spot locations and elevations must be called out for all high points of emergency overflow swales. m) A notation should be added to the plan requiring periodic inspections under the NPDES permit. If 10 or more contiguous acres of exposed soil are draining to the same area, a temporary sedimentation basin is required under NPDES rules. n) If construction traffic will be allowed at the right- in/right-out off of Fremont, a rock construction entrance is required. 0) The use of the storm ceptor must be approved by the Watershed District. Calculations to determine if the pipe is sized adequately to handle the flows must also be provided. p) Consider revising the storm sewer layouts on sheets 8 and 16 to reduce the length of pipe needed to serve the project. q) Catch basin intercept calculations will be required before final plat approval. r) Set the outlet elevation for Pond 4 at the flood storage level required for two back to back 100 year storms. s) The outlet for NURP #2 is 2.5 feet lower than the elevation of Wetland Basin '~" (Pond 5). Additional survey shots are required to verify the bottom elevations of Wetlands/Ponds 4 and 5. t) The stage/storage curve for Pond 5 should be checked, The area for elevation 902. 1 should be 0.0 acres, and the area for 904 should be 1.5 1:\98files\98subdiv\preplat\glynwate\glyncc.doc Page 4 acres. u) Continue to look at alternatives other than the parallel line to provide sanitary sewer. If the parallel lines are the best alternative, a heavy duty trail to maintain the sewer in the park area is required, This trail and access must be shown on the plans. 4. Signs in the common lot area may not be located within a utility easement. 5. An access permit from the Scott County Engineer is required for each location connecting to CSAH 82. This permit must be supplied prior to final plat approval. 6. The sanitary sewer crossing under CSAH 82 must be bored and placed in a steel casing. A utility permit will be required prior to installation. 7. Any grading or utility work within the County right-of- way will require a permit prior to construction. Evidence of this permit must be submitted to the City prior to final plat approval. On March 4, 1998, the Developer submitted a revised set of plans which address several of the conditions listed above. These plans are attached for your information. Planning Staff Recommendation: The Planning staff also recommends approval of these requests. The conditions listed on the attached resolutions reflect the revised plans. ISSUES: One of the issues which must be addressed is the disturbance of the slopes on this site. Section 6-6-6 E of the Subdivision Ordinance states "whenever possible, slopes of twenty percent (20%) or greater should not be disturbed and should be retained as private or public open space." This plat has several locations in which slopes of 20% or greater are disturbed, either for the placement of roads and utilities or the placement of homes. It appears the only way to avoid theses slopes is to eliminate buildings. It may also be necessary to relocate some of the utility lines to avoid the slopes. The Planning Commission felt the design of the site provided the least disturbance possible for this development. The other issue with this application is the final plans for the Conditional Use Permit. While the Developer has submitted revised plans, they do not reflect all of the conditions of approval. The Developer must submit a final set of plans which will be attached as an exhibit to the I :\98files\98subdiv\preplat\glynwate\glyncc.doc Page 5 resolution. It is this set of plans which will be used to determine the pattern of development on the site and to issue permits. Approval of the Conditional Use Permit without the final set of plans can be done in either of two ways. The Council may approve the resolution, but direct that it not be recorded until all plans are submitted. Or, the Council may indicate its general approval of the Conditional Use Permit, but delay formal approval of the resolution until final plans are submitted. Once the Developer has submitted the final plans, the resolution can be placed on the Consent Agenda. ALTERNATIVES: 1. Adopt Ordinance #98-XX amending the designated zoning district from the A-1 district and the C-1 district to the R-2 district, adopt Resolution 98-XX approVing the Conditional Use Permit for this development subject to the listed conditions, and adopt Resolution #98-XX, approving the preliminary plat of Glynwater subject to the listed conditions, with the finding that the preliminary plat is consistent with the intent and purpose of the Comprehensive Plan and the Zoning and Subdivision Ordinances. 2, Adopt Ordinance #98-XX amending the designated zoning district from the A-1 district and the C-1 district to the R-2 district, and adopt Resolution #98-XX, approving the preliminary plat of Glynwater subject to the listed conditions, with the finding that the preliminary plat is consistent with the intent and purpose of the Comprehensive Plan and the Zoning and Subdivision Ordinances. Defer action on Resolution 98-XX approving the Conditional Use Permit for this development until final plans are submitted. Once the final plans are submitted, this Resolution should be place on the Consent Agenda. 3. Defer consideration of this item for specific reasons. 4. Deny the rezoning request and thus find the conditional use permit and the preliminary plat inconsistent with the purpose and intent of the Zoning and Subdivision Ordinances and/or the Comprehensive Plan. RECOMMENDATION: Upon rezoning of the property, the conditional use permit and the preliminary plat appear to be adequate and appropriate for the development of the site with public sanitary sewer and water. Final action on the Conditional Use Permit should be delayed until the Developer submits final plans. On that basis, staff recommends Alternative #2. 1:\98files\98subdiv\preplat\glynwate\gfyncc.doc Page 6 ACTION REQUIRED: Since there are three separate actions involved in this approval, three separate motions are required, as follows: 1. Motion and second to adopt Ordinance 98-XX approving the zone change to the R-2 district. A 4/5 vote of the Council is required for approval of a rezoning. 2. Motion and second to adopt Resolution 98-XX approving the Preliminary Plat subject to the listed conditions, 3. Motion and second to defer action on Resolution 98- XX approving the Conditional Use Permit until the Developer submits final plans. Once final plans have been submitted, direct the staff to place the Resolution on the Consent Agenda. EXHIBITS: A. Ordinance 98-XX B. Conditional Use Permit Resolution #98-XX C.

This property is currently zoned A-I (Agriculture) and C-1 (Conservation). Much of the property is also located within the Shoreland District for Prior Lake and Arctic Lake. The applicant is requesting the property be rezoned to the R-2 (Urban Residential) district. The application also includes a request for a conditional use permit to allow the development of the property with 121 townhouse units, and a preliminary plat consisting of 109 lots for the townhouse units and open space. BACKGROUND: In December, 1997, the applicant filed an application for a Schematic Planned Unit Development for a townhouse development on this property. On January 5, 1998, the city Council denied this application based on the fact the proposed Schematic PUD Plan was inconsistent with the stated purposes and intent of the PUD section of the Zoning Ordinance in that the same proposal, with the exception of the private streets, could be accomplished through the Conditional Use Permit Process. The developer then filed these applications to develop the property. The Planning Commission is considering three applications at this time. The first application is a request to rezone the property from the A-I (Agricultural) and C-1 (Conservation) districts to the R-2 (Urban Residential) district. The second request is to approve a Conditional Use Permit for this project. The third application is for approval of a preliminary plat for this site, to be known as Glynwater. Each of these applications is discussed in detail below. 1:\98files\98subdiv\preJ11at\gl~wate\glyt1pc.doc 'pagj: J 16200 Eagle Creek Ave. ::"E., Prior LaKe, Minnesota 55372-1714 / Ph. (612) 447-4230 / Fax (61L) lf47-4245 AN EQUAL OPPORTUNITY EMPLOYER PHYSICAL SITE CHARACTERISTICS: Total Site Area: The total CUP area (less the CSAH 82 right-of-way) consists of 41.57 acres. Topo~raphy: This site has a varied topography, with elevations ranging from 970' MSL at its highest point to 910' MSL at the lowest point. The site generally drains towards the wetlands located along the easterly portion of the site, the southerly portion and the center of the site. There are also steep slopes, or slopes in excess of 20%, located on this site. These slopes are generally located on the eastern half of the site. There are several areas in which the steep slopes will be disturbed by the placement of building pads and utilities. Ve~etation: This vegetation on this site consists of vacant cropland. The eastern and southern boundaries of the property are wooded, as is the area adjacent to the wetlands. The project will be subject to the Tree Preservation requirements of the Zoning Ordinance. The applicant has submitted an inventory of the significant trees on the site which indicates a total of 203 caliper inches of significant trees. Based on the development plan, 29% of the caliper inches will be removed for grading and utilities, and 5% will be removed for building pads. The development will require replacement of 4.38 caliper inches. Wetlands: There are three wetlands located within this site, with a total area of 9.45 acres. The wetlands are located in the southeast comer of the site, along the southern boundary of the site, and in the center of the site. The plans indicate only a small area of wetlands will be filled to allow a road connection. This site is subject to the wetland mitigation requirements. Access: Access to the site is from CSAH 82, on the north. CSAH 82 is identified as a Minor Arterial street in the 2010 Comprehensive Plan. The County Engineer has noted an access permit will be required for each opening onto CSAH 82. PROPOSED PLAN 2010 Comprehensive Plan Desi~nation: This property is designated for Urban Low to Medium Density Residential uses on the 2010 Comprehensive Plan Land Use Map. The easterly portion of the property is located within the 2010 MUSA boundary. The westerly portion of the property is still outside of the MUSA. Zonin~: The developer has filed an application to rezone this property to the R-2 (Urban Residential) district. The R-2 district is consistent with the Comprehensive Plan designation. Density: The plan proposes 121 units on a total of 41.57 acres. Density is based on the buildable acres of the site, or in this case on 32.12 net acres. The overall density proposed in this plan is 3.7 units per acre. The R-2 district permits a density of 5.5 units per acre through the CUP process. 1 :\98fi1es\98subd i v\prep 1at\glynwate\glynpc .doc Page 2 -----=-~--~-- - C~ Lots: The preliminary plat consists of 109 lots for the townhouse units and open space. There are 103 lots for the buildings, and 6 lots for common open space. The plat also includes parkland, and an outlot, located at the intersection of CSAH 82 and Glynwater Trail for a sign. Buildin~ Styles: The proposed plan calls for a townhouse style development consisting of 2-, 3-, 4-, 5- and 6-unit buildings. Sample floor plans ofthese buildings are attached to this report. There are 18 2-unit buildings, 2 3-unit buildings, 17 4-unit buildings, and 1 each of the 5- and 6-unit buildings. Each of the buildings is designed with an attached garage, Setbacks: The plan proposes a 25' setback from the front property line, and the side street lot line, a 25' rear yard setback from any common lot line, and a minimum 20' separation between the buildings. This is consistent with conventional setbacks. Lot Covera~e: The R-2 district allows a maximum lot coverage of 20% for a townhouse PUD. The proposed plan indicates a lot coverage of approximately 14%, which is consistent with the proposed plan. Streets: This plan proposes 4 new public streets. The major street, named Glynwater Trail, starts on the east side of the site, directly opposite Wilds Parkway, loops through the site for 2,650' and exits back onto CSAH 82. This street is designed with a 55' wide right-of-way and a 32' wide surface. The second street, Bayview Drive, is located on the east side of the site, and extends 625' from Glynwater Trail to Fremont Avenue. This street is designed with a 50' wide right-of-way and a 32' wide surface. The third new street is a 600' long cul-de-sac identified as Spring Glen Circle. This street is located on the east portion of the site, and on the west side of Glynwater Trail. It is designed with a 50' wide right-of-way and a 32' wide surface. Finally, there is a 130' long stub street located on the west portion of the site which provides future access to the property to the west. This street is identified as Spring Glen Road and is designed as a 50' wide right-of- way and a 32' wide surface. SidewalkslTrails: There is a sidewalk located along the north end of Glynwater Trail from CSAH 82 to the park trail on the east, and from CSAH 82 to Spring Glen Road on the west. A sidewalk is also proposed along the north side of Bayview Circle from Fremont Avenue to Glynwater Trail. The plan also identifies a pedestrian trail starting at CSAH 82, winding through the proposed park, and connecting to the 16.5 foot wide access owned by the City on the west boundary of this site. Parks: This plan identifies a park along the south boundary of the property. The total park site is 11.91 acres; however, much of the area consists of wetlands and ponds and steep slopes. The parkland dedication requirements for this site is 4.2 acres, consisting of dry upland with undisturbed soils. If the land area to be dedicated does not include 4.2 acres of this type of land, the remaining dedication requirements will be made as a cash dedication. I: \98 fi 1es\98subdi v\prep lat\gIynwate\gl ynpc .doc Page 3 Sanitary Sewer: The plan proposes the extension of an 8" sanitary sewer line from the existing line located on the north side of CSAH 82 at Fremont Avenue. The development will actually be served by parallel sewer lines. The main sewer line is located in Glynwater Trail on the west side of the site, to the park, and then runs through the park behind the townhouse units to Fremont Avenue. The second line is located on the east side of Glynwater Trail and flows from Spring Glen Circle west to the park, where it connects to the main sewer line. The reason this development is designed with the parallel lines is the fact that a single line would have to be about 45' deep in some locations. At this depth, it is more cost effective to run the parallel lines. Maintenance of a 45' deep sewer line is also difficult and expensive. Water Main: The plan proposes to extend an 8" water line from the existing service located in CSAH 82, down Glynwater and the other road right-of-ways to serve the units. There will be 4 service lines extended from the main in CSAH 82 to serve the units along Bayview Circle. Storm Sewer: The plan proposes two NURP ponds, one located on the east side of the site, just south and west ofthe Spring Glen Circle cul-de-sac, and the other located on the west side of the site, just south and east of Spring Glen Road. Storm water runoff is directed to these ponds through a series of catch basins and storm sewer located in the Glynwater Trail and Spring Glen Road. The developer is also proposing to direct runoff from Bayview Drive to the wetland to the south through a storm ceptor pipe. A storm ceptor is a pipe which filters the sediment and eliminates the need for a NURP pond. The use of this pipe must be approved by the Watershed district prior to approval. Landscapin~/Tree Replacement: The developer has submitted a landscaping plan which identifies a total of 206 new trees on the site. Most of the trees will be located in front of the units along the new road right-of-way. The plan also identifies several plantings and a berm adjacent to CSAH 82 to provide screening from the road. Finally, the plan identifies the two replacement trees required as part of the tree preservation plan. Si~na~e: This proposal identifies 9 development signs. The Zoning Ordinance allows 2 freestanding subdivision identification signs at each principal entrance. The signs may not exceed 50 square feet in area, with a maximum of 2 sides. This development consists of 3 separate association, so it is probably reasonable to allow a total of 6 development signs, rather than the 9 proposed. The signs are within the allowable area. The plan, however, should be revised to identify where each type signs will be located. Phasine: Since not all of this site is located within the present MUS A, the development will be phased accordingly. The first phase will be that portion within the MUS A, and includes 82 units. There will be a temporary turnaround located at the westerly end of Glynwater Trail until the remaining area is added to the MUSA and is developed. ANALYSIS: 1: \98files\98subd iv\prep 1at\glynwa te\gl ynpc,doc Page 4 Zone Chanee Request: The applicant is requesting a zone change to the R-2 district to allow for development of this site. The criteria for granting a zoning change include the following: 1. There was a mistake in the original zoning 2. Conditions have changed significantly since the current zoning was adopted. 3. The Comprehensive Plan has been amended. Any of these criteria can be used to evaluate a request for rezoning. The "Year 2000 Comprehensive Plan" for the City of Prior Lake, adopted in 1982, designated this area as "Agricultural". The A-I and C-l districts are appropriate for that designation. However, with the adoption of the 2010 Comprehensive Plan in June, 1996, this area was added to the Municipal Urban Service Area and designated as R-L/MD. The R-2 district is an appropriate zoning district for the R-LIMD designation. Preliminary Plat: The preliminary plat for this site, known as Glynwater, consists of 42.04 acres to be subdivided into 109 lots, parkland and an outlot. In general, the proposed preliminary plat meets the standards of the Subdivision Ordinance and Zoning Ordinance. There are some engineering and ordinance requirements which still must be addressed prior to approval of this preliminary plat. One of the outstanding issues which must be addressed is the disturbance of the slopes on this site. Section 6-6-6 E of the Subdivision Ordinance states "whenever possible, slopes of twenty percent (20%) or greater should not be disturbed and should be retained as private or public open space. " This plat has several locations in which slopes of 20% or greater are disturbed, either for the placement of roads and utilities or the placement of homes. It appears the only way to avoid theses slopes is to eliminate buildings. It may also be necessary to relocate some of the utility lines to avoid the slopes. In its recommendation to the Council, the Planning Commission should address the impact of the development on the natural features of the site. Conditional Use Permit Plan: The proposed CUP must be reviewed in accordance with the criteria found in Section 7.5(C) of the Zoning Ordinance. Section 7.5(C) provides that a conditional use shall be approved if it is found to meet specific criteria. These criteria and the staff analysis of compliance with these criteria are set forth below. 1. The proposed use conforms to the district permitted and conditional use provisions and all general regulations of this Ordinance. The proposed use is consistent with the conditional use prOVlSlons for the R-2 Multiple Residential zoning district and conforms to all general regulations of the Zoning Ordinance (upon satisfaction of conditions). 2. The proposed use shall not involve any element or cause any conditions that may be dangerous, injurious, or noxious to any other property or persons, shall comply with the performance standards listed below. 1: \98files\98subdi v\prep lat\glynwate\glynpc .doc Page 5 The proposed development is designed to provide safe access to adjacent roads, and is adequately screened from adjacent properties. 3. The proposed use shall be sited, oriented and landscaped to produce harmonious relationship of buildings and grounds adjacent to buildings and properties. The landscaping plan submitted with this proposal meets the provisions of the ordinance. Additional landscaping is provided to screen the development from CSAH 82. 4. The proposed use shall produce a total visual impression and environment which is consistent with the environment of the neighborhood. The size and types of buildings proposed are consistent with the adjacent development. 5. The proposed use shall organize vehicular access and parking to minimize traffic congestion within the neighborhood. The plan provides at least 2 parking spaces for each unit. In addition, in order to minimize traffic onto Fremont, the access is defined as a "right-inlright-out" turn, with a median. 6. The proposed use shall preserve the objectives of this Ordinance and shall be consistent with the Comprehensive Plan. The proposed plan is consistent with the Comprehensive Plan designation and the provisions of the R-2 district. The performance standards are set forth in Section 7.5(D) and relate to the following factors; . Fire protection . Electrical disturbance . Noise . Vibrations . Odors . Air pollution . Glare . Erosion . Water pollution. The proposed project is not expected to result in any of the nuisance factors set forth in the performance standards and is thus consistent with these standards. PLANNING COMMISSION RECOMMENDATION: At this time, the Planning Commission should make a recommendation on the proposed zone change request, the Preliminary Plat and the Conditional Use Permit. 1: \98fi les\98subdiv\prep1at\glynwate\glynpc .doc Page 6 If the Preliminary Plat is to proceed, it should be subject to the following conditions: 1. Change the name of Bayview Drive. There is already a Bayview Circle in the City street system. In addition, change the name of Spring Glen Road or Spring Glen Circle so there is only one Spring Glen. 2. Outlot B must be identified as Outlot A. 3. Provide the following information on the Engineering Plans: a) Show all utilities in the profile view. b) Show size of all existing utilities in the area. c) Include insulation detail to be used on sanitary sewer. d) Provide calculations showing that the pavement section is adequate (see plate #501 in the Public Works Design Manual). e) Street grades within 100 feet of intersections cannot exceed 2.00 percent. f) Provide design and profiles for the median and the street improvements to Fremont. The City may be willing to share in the engineering costs for this design as per the City oversizing policy. g) Show the construction limits on the grading plans. The grading and installation of the sanitary sewer will impact the 20% slopes. h) Indicate on the plan areas where slopes are greater than 5:1. i) The wetland report indicates a wetland "water course" flowing south from basin B to basin A. A road and grading is proposed over this water course. The wetland report must be revised to address the impact of this filling and grading on the water course. j) NURP ponds shall have 6:1 slopes below the NWL, and 4:1 slopes above the NWL. k) Show the grading detail for the Ramble Walkout. There is a 10' grade difference for Lots 1-6, Block 1. I) Spot locations and elevations must be called out for all high points of emergency overflow swales. m) A notation should be added to the plan requiring periodic inspections under the NPDES permit. If 1 0 or more contiguous acres of exposed soil are draining to the same area, a temporary sedimentation basin is required under NPDES rules. n) If construction traffic will be allowed at the right-in/right-out off of Fremont, a rock construction entrance is required. 0) The use of the storm ceptor must be approved by the Watershed District. Calculations to determine if the pipe is sized adequately to handle the flows must also be provided. 1: \98fiIes\98subdiv\prep 1a t\gl ynwate\gl ynpc .doc Page 7 p) Consider revising the storm sewer layouts on sheets 8 and 16 to reduce the length of pipe needed to serve the project. q) Catch basin intercept calculations will be required before final plat approval. r) Set the outlet elevation for Pond 4 at the flood storage level required for two back to back 100 year storms. s) The outlet for NURP #2 is 2.5 feet lower than the elevation of Wetland Basin "A" (Pond 5). Additional survey shots are required to verify the bouom elevations of Wetlands/Pond 4 and 5. t) The stage/storage curve for Pond 5 should be checked, The area for elevation 902.1 should be 0.0 acres, and the area for 904 should be 1.5 acres. u) Continue to look at alternatives other than the parallel line to provide sanitary sewer. If the parallel lines are the best alternative, a heavy duty trail to maintain the sewer in the park area is required. This trail and access must be shown on the plans. 4. Define the easements in the common lot area to cover the appropriate areas; the easements should not cover the entire lot area. 5. An access permit from the ScoU County Engineer is required for each location connecting to CSAH 82. This permit must be supplied prior to final plat approval. 6. The sanitary sewer crossing under CSAH 82 must be bored and placed in a steel casing. A utility permit will be required prior to installation. 7. Any grading or utility work within the County right-of-way will require a permit prior to construction. Evidence of this permit must be submiued to the City prior to final plat approval. It should be noted that revised plans were submitted which may address some of these issues. However, these plans were not submitted in time to allow a detailed review. If the Conditional Use Permit IS approved it should be subject to the following conditions: 1. Six identification signs will be permiUed on the site. The signage plan must be revised to identify the locations of these signs, and to clarify the location of each type of sign. If a sign is located adjacent to the park access on the east side of Glynwater Trail, no portion of the sign or fence is permiUed in the parkland, 2. The plan must provide a calculation showing the impervious surface, not including road right-of-way, on the portion of the site located within the Shoreland District. The impervious surface of the site in the Shoreland District may not exceed 30% of the site area, less right-of-way. 3. The plan must identify Phase I and Phase II of the development. The plan must also note that Phase II will not be allowed to develop until the properly is included within the MUSA, and services can be extended. 1: \98files\98su bdiv\prep 1at\glynwate\glynpc .doc Page 8 ---- ~ 4. A letter of credit for the landscaping and tree replacement must be submitted prior to approval of the final plat documents. 5. The homeowner's association documents must be revised to include the correct legal descriptions for each association. These documents must be recorded with the final plat documents. 6. A new set of plans, showing all of the revisions, must be submitted prior to final approval of the conditional use permit. ALTERNATIVES: 1. Recommend approval of the Zone Change, the Preliminary Plat subject to the above listed conditions, and the Conditional Use Permit subject to the above listed condition. 2. Recommend denial of the request. 3. Other specific action as directed by the Planning Commission RECOMMENDATION: The Planning staff recommends Alternative 1. It may be appropriate, due to the number of outstanding engineering issues, to delay action on the preliminary plat until the major issues are addressed. ACTION REOUIRED: Since this request includes three separate applications, separate motions are required for each application. These include; 1. A motion and second to recommend approval ofthe Zone Change request from the A- I and C-I districts to the R-2 district. 2. A motion and second to recommend approval of the Preliminary Plat to be known as Glynwater, subject to the conditions listed in this report. 3. A motion and second to recommend approval of the Conditional Use Permit, subject to the conditions listed in this staff report. EXHIBITS: 1. Location Map 2. Reduced Copy of Conditional Use Permit and Preliminary Plat Plans 3. Developer's Narrative 4. Comments From Scott County Engineer 5.

Townhomes (split entry), Twin homes and Coach homes. Prices will range from $115,OOO-$350,OOO with the average approx. $180,OOO. 3-Density The proposed development has 122 units on 41.57 acres. Densities are within the allowable limits for R-2 zoning and are also within densities in the governing shoreline districts that apply. 4- Design Features The site maximizes the use of the land away from the shorelines. Public streets service the site and a proposed trail system winds through the entire development. Developer will be dedicating approx. 11.69 as parkland of which 4.95 acres are usable and the balance wetlands and ponds. The developer does not plan to construct the trail system as part of this development it is shown for schematic reference only. The trail would be constructed separately as a Park & Recreation Dept. project. 5- Architecture Building designs have been created to maximize the natural terrain. Extensive landscaping along Co. 82 and a brick & wrought iron fence will accentuate the development. A community entry monument is planned just off the main Co. 82 entrance. The proposed trail system will provide enjoyment for passive recreation. Side wall are proposed only at the Co. 82 entrances until they meet with the proposed trail system. 6-Covenants Protective covenants for the three townhome communities will be filed to provide continuity and control over the esthetics of the communities. Proposed documents are enclosed for city review and approval. 7-Utilities The development will be serviced with underground utilities. Gas meters will be located on the fronts on the homes with electrical services in the rear. The Townhomes and Twin homes will have individual water services and the coach homes will have one service per building. Engineering Project Summary for Glynwater . In Prior Lake 1. Description of Project The site is approximately 45 acres located south of Scott County Road 82 and west of Fremont Avenue, in the City of Prior Lake. The subject site is in the NE 1/4, SW 1/4 of Section 34, Township 115, Range 22, Scott County, Minnesota. The proposed project includes the grading, utility and street construction for 122 single family townhomes, and condominiums. The grading for the site will occur at one time with the streets and utilities constructed in two phases, The first phase is the eastern portion of the site up to the existing MUSA line to the west. The second phase will be the remainder of the site once it is brought within the City of Prior Lakes MUSA boundary. II. Project Manager The project manager and project engineer shall be responsible for various aspects of the construction and are as follows: Proiect Manager Terry Wensmann{tllI1'-lI'1uvr*-1 Wensmann Realty,rY\t.... } 3312 151" Street West Rosemount, Mn 55068 423-1179 Proiect Engineer Nicholas Polta Pioneer Engineering 2422 Enterprise Drive Mendota Heights, Mn 55124 681-1914 III. Existing Site Conditions The site is currently undeveloped. The northern portion of the site is primarily cultivated cropland and upland forest. The sothern portion of the site is upland and lowland forest, wet meadow and shallow marsh. The southern parcel boundary follows a watercourse (seasonal flooded creek) that flows east connecting the two large basin portions of Wetland A with Prior Lake. A second basin ( Wetland B ) drains south into the western portion of Wetland A. Much of the site shows signs of disturbance particularily in the cultivated upland areas. The surrounding land uses are residential to the south, east, and northeast. North and west are in agricultural uses. IV. Soils and Slopes The United States Department of Agricultures Soil Survey identifies the onsite soils are primarily Hayden Series these soils are described as good for embankment and foundations. The lowlands and wetlands contain peat and Glencoe series soils that are not suitable for construction, these areas will be avoided during construction. Comprehensive soil testing was performed onsite by Maxim Technologies (report inclosed), there analysis substantiates the suitability of the onsite soils for the construction purposes of the development. Topsoil will be stripped and stockpiled onsite to provide for six (6) inches of repsread across all turf areas after completed grading. The site has 5.33 acres of slopes in excess of 20 percent (%). These slopes are clustered near the wetlands and appear to have been disturbed or created during the construction of Co. Rd. 82 and Fremont Avenue. The construction of the project will disturb 1.64 acres (30.69%) of these slopes. Approximately 0.73 acres of this disturbance will occur in excavation areas ( where the slopes are flattened at the top for the construction of streets and building pads, matching back in further down the slope), these areas pose little concern in construction as long as the underlying soils are suitable for construction. During construction a geotechnical engineer will be onsite inspecting soil conditions and providing analysis of the soils. The remaining 0.91 acres of disturbed slopes are in embankment areas. In these areas unsuitable slope material will be removed and replaced with soils that can bear the load of streets and building footings. The embankment will be 'keyed' into the existing slopes and built up in layers to prevent embankment slipping over the existing slopes causing failure. This is standard construction practise and is further outlined in the Soils Report prepared by Maxim technologies. v. Erosion Control Measures Approved best management practices (BMP) of the Minnesota Pollution Control Agency (MPCA) as stipulated in Protecting Water Ouality in Urban Areas shall be followed. These include but are not limited to the following: All denuded and stockpile areas shall not have a slope greater than 3: I All disturbed area shall receive temporary seed, mulch and disc anchoring if no significant grading is to occur for 30 days. All finished grade area shall be seeded mulched and anchored within 14 days after complete grading. A seed mixture designed for the soil characteristics and area plantings shall be approved oj' tl~e C i(y" Eng:llccC. A separate cool seed mixture will be designed for dormant seed planting in the fall. Peak Discharge from all storm sewers shall not exceed the original peak discharge from the watershed. All storm sewer outlets shall have rip rap outlets designed to City Standards. All Storm Sewer outlets shall not have discharges greater than 4 feet per second. Gravel construction entrances and a street sweeping program shall be used to ensure minimal soil is removed from the site. Inlet protection for storm sewer shall be implemented until streets are paved and turf is established, Erosion control fences shall be installed around all wetlands and water quality ponds until area plantings have been established. At which time the erosion control fence shall be moved to the edge of the structure setback. Water quality ponds will be used as temporary sedimentation basin during construction. The grading contractor is responsible for maintaining drainage to the ponds and between the ponds and wetlands, by the use of perforated stand pipes. VII. Storm Water Management The purpose of storm water managemen: is to insure that the proposed development will not create adverse conditions, in the form of increased nutrient load or increased peak flows down stream of the proposed project. To assess that impact of the project on the existing drainage area a preliminary storm water model (HydroCAD) is utilized to approximate the existing and proposed peak flows generated for the site. The Walker PondSiz model created the criteria for the wet detention volume necessary to treat storm water from this development. These models are summarized below in Table 1. Vln. Wetland Delineation Peterson Environmental Consulting, Inc. have prepared a detailed Wetland Delineation Plan for the subject property. IX. Traffic Control The contractor is responsible to provide to the City of Prior Lake and the Scott County Highway Department a detailed traffic control/sign plan for construction of turn lanes on Co. Rd. 82 and Fremon: Avenue. XI. Construction Sequencing The following is a fcugh schedule for construction. contingent upon the approval of the project by all pertinent regulatory agencies : 1.

Due to time restraints some of the items are not completed and others are partially completed. Work will progress on the remaining items with additional input from City staff. Sanitary Sewer and Watermain 1. The grading plan is adjusted to provide at least 5' of cover with an average of 7' . 2. Utility crossings will be shown in profile on the final construction plans. I am confident their are no insurmountable conflicts. 3. SDR 26 sanitary sewer pipe is used he low 16 feet. 4. Utility Lines are shown in profile for Bushmill Road now Spring Glen Road. 5. Size of exis ting utilities is shown. 6. Insulation of sanitary sewer with depths of less than 7' will be consistent with the insulation detail for water main shown in the detail plates. 7. Final alignment of sanitary sewer is subject to change, depending on research into the use of the lift station on Fremont Avenue and the Sioux Communities installation of a new trunk sanitary sewer line. Plat 1. Street right-of-way width are shown. 2. All easements are shown. Easements are subject to change, due to utility and ponding alignment changes. The final easements will not be filed until the final plat. 2422 Enterprise Drive · Mendota Heights. Minnesota 55120 · (612) 681-1914 · Fax 681-9488 625 Highway 10 N.E. · Blaine. Minnesota 55434. (612) 783-1880 . Fax 783-1883 Streets 1. Typical street section has been changed to match City detail Plate. 2. Maxim Technologies (Geotechnical Engineers) are reviewing the soil samples from the site to determine the adequacy of the proposed pavement section. The calculations will be available prior to City Council action. 3. Due to time constraints, the street grades within 100' of intersections have not been reduced to 2.00%. I have reviewed the intersections and made the changes but ran out of time to redraft them. 4. A median in Fremont Avenue has been added to restrict left turn movements from the Glynwater addition. I will be working with City staff to finalize improvements to Fremont Avenue. Additional plans will be provided once the details are worked out. Gradine 1. NWL and HWL are shown for p'~~nds and wetlands. 2. Due to time constraints the existing grade contours north of the County Road could not be shown. They will be added for final submittal. 3. Ponds and Wetland are labeled for identification. 4. Heavy duty silt fence is specified around wetlands. Silt fence around ponds will be added later. 5. The impact to steep slopes has been minimized. 6. The grading plan shows all slopes greater than 20 % . 7. Wood fiber blanket is specified for created slopes greater then 3: 1. .. ,~. 8. The wetland "water course" is shown from wetland basin B to basin A. The installation of the road over the watercourse will require the filling of approximately 200 s.f. of wetland. 9. Due to time constraints the NURP ponds have not been redesigned to show the City standard slopes. The NURP ponds are shown much larger than are required. The slope changes will not effect the sites ability to treat its stormwater. 10. Since the ponds were not redrawn lots 34-37 , block 2 still do not meet setback requirements. This will be change when the ponds are redrawn. 11. Lots 39 and 40 house pad designation changed. 12. Grading detail for condominium buildings is shown with a 10' grade difference. 13. Pond 2 was deleted with a Cretex Stormcepter proposed in its place. It is our understanding that City staff approved this February 12, 1998. We still need to convince the watershed district. 14. See 1 15. Spot elevations for overflows wiil be added when the ponds are redrawn. 16. A copy of the NPDES permit is provided in the Specifications placing the responsibility of the permit on the general contractor. 17. Construction traffic will not use Fremont Avenue. Stonn Sewer 1. Due to time constraints, additional field work was not performed. 2. Storm sewer layouts were revised at the Cities direction. 3. Catch basin intercept calculations will be provided at final plat. 4. The stormwater management plan will be updated once the ponds are redrawn. At that time, the elevation of Pond 4 under two 100 year storms can be determined. 5. Pond 2 was eliminated. 6. Due to time constraints addition field work was not performed. This information will be gathered at a later date. 7. The stage storage information for pond 5 appears correct. 8. Sump catch basin details are included in the City details sheets 20-21. If you have any questions or require any further information please feel free to call.

This should include the existing and proposed conditions and a summary denoting any change. Show where the wetland in Block 2 outlets. · An access permit will be required for each location connecting to CSAH 82. · The sanitary sewer crossing under CSAH 82 will need to bored and placed in a steel casing. A utility permit will be required prior to installation. · The maximum allowable profile grade is 2% for the first 100 feet from the outside edge of County Highway shoulder. Your easterly access with CSAH 82 shows a 2.25% grade from the center of CSAH 82, and should be revised. The westerly access shows 2%, however it is not clear if that matches with the edge of shoulder or again with centerline of CSAH 82. · A signing plan for the CSAH 82 turn lane must be done in accordance with MMUTCD and be approved by Scott County prior to work. A work within RJW permit must also be acquired prior to work. · We request the opportunity to review the final plat and construction plans. ; ~ Ii j i J; !.,,'" / '1./ An Equal Opportunity/Safety Aware Employer Jane Kansier G Iynwater Page 2 General Comments · The right turn lanes as shown are acceptable. · No berming, landscaping, ponding, curb & gutter, sidewalk, or signing will be allowed within the County right-of-way. . Any grading or utility work required within the County right-of-way will require a permit prior to the work commencing. . A temporary rock pad is required on the internal streets connecting to CSAH 82 to prevent dirt from being tracked onto CSAH 82 during the grading operation. Sweeping of CSAH 82 shall be done as required by the County. Thank you for the opportunity to comment. Please contact us if you have any questions or need additional information.

The property currently is NOT served with municipal sewer and water utilities. At the time municipal utilities become available the subdivision will be subject to the following City charges: Stormwater Management Fee Collector Street Fee Trunk Sewer & Water Fee Lateral Sewer & Water Charge 16.8 cents/sq.ft. $1500.00/acre $3500.00/acre 150' @ $60.00/ff The application of these City charges would generate the following costs to the developer based upon a net lot area calculation of 28.13 acres of townhouse units (1,225,548 sq. ft.) as provided within the site data summary sheet of the preliminary plat description: Lateral Sewer & Water Charge: 150' @ $60.00/ff= $9,000.00: Trunk Sewer & Water Charge: 28.13 acres @ $3500.00/ac = $98,455.00 Storm Water Management Fee: 1,225,548 sf@ 16.8/sf= $205,892.00 Collector Street Fee: 28.13 acres @ $1500.00/ac = $42,195.00 These charges represent an approximate cost of$2938.00 per lot for the 121 proposed townhouse units within Glynwater. Assuming the initial net lot area of the preliminary plat does not change, the above referenced storm water, collector street, trunk and lateral sewer and water charges would be determined and collected within the context of a developer's agreement for the construction of utility improvements at the time of final plat approval. There are no other outstanding special assessments currently certified against the property, Also, the tax status of the property is current with no outstanding delinquencies. 16200 Eagle Creek Ave. S,E., Prior Lake, Minnesota 55372-1714 / Ph.

It should be noted that revised plans were submitted which may address some of the issues outlined by the staff. However, these plans were not submitted in time to allow a detailed review. 1 :\98files\98plcomm\pcmin\mn022398,doc 9 The staff also suggested six conditions which should be attached to the Conditional Use Permit if it is approved. The Planning staff recommends approval of the Zone Change, the Preliminary Plat subject to the above listed conditions, and the Conditional Use Permit subject to the above listed condition.
