Prior Lake, MN 55372-1714 MEETING DATE: AGENDA #: PREPARED BY: SEPTEMBER 15, 2003 9B JANE KANSIER, PLANNING COORDINATOR AGENDA ITEM: CONSIDER APPROVAL OF A RESOLUTION APPROVING A PLANNED UNIT DEVELOPMENT PRELIMINARY PLAN, AND APPROVAL OF A RESOLUTION APPROVING A PRELIMINARY PLAT TO BE KNOWN AS CRYSTAL BAY I ! I I I I ! DISCUSSION: Introduction: 212 Development, LLC, has applied for approval of a development to be known as Crystal Bay on the property located south of CSAH 82, directly east of Fremont Avenue and approximately Y, mile west of CSAH 21. The application includes the following requests: · Approve a Planned Unit Development Preliminary Plan; . Approve a Preliminary Plat. The proposal calls for a townhouse development consisting of 24 dwelling units on 10.62 acres. The development also proposes private open space and 21 boat slips for the use of the residents. i r: ;1 ~ , History: The City Council approved a preliminary plat and preliminary PUD plan for this development on October 7, 2002. However, when the developer submitted the final plan, there were some changes that were inconsistent to the approved preliminary plan. As a result, the developer has chosen to resubmit a preliminary plat and preliminary PUD plan application. The general provisions of the proposal have not changed. The details of the plan and the proposed changes are discussed in the following paragraphs. I': ,I Ii :1 II II II The Planning Commission conducted a public hearing on this item on September 8, 2003. Three residents of the surrounding area testified about the proposed development. Their primary concerns were the value of the homes, tree removal, the length of the dock, the use of pervious pavers, noise and the access onto Fremont A venue. The Planning Commission addressed these concerns as follows: 1:103 filesl03 subdivisionsl03 prelim platl03 crystal bavlcc.Le11.Qrl.docl k WWW.clLyoIpnorae.com Page 1 Phone 952.447.4230 / Fax 952.447.4245 . The value of the proposed townhomes is consistent with the surrounding area. . The proposal includes a large number of trees along CSAH 82, which will function as a noise barner. . The length ofthe dock will be reviewed as part of the permitting process. The Commission encouraged the developer to look closely at the dredging of the lake. . The overall impervious surface ofthe site is less than 30 percent. Tier 2, the area which exceeds 25% impervious surface, actually drains away from the lake. . The access onto Fremont Avenue is located as far south of the intersection of CSAH 82 as possible. The second access is important for the development, and this entrance will provide access to 12 townbomes. 'I ~ II i ~ II II I i A copy ofthe draft minutes ofthe September 8, 2003 Planning Commission meeting is attached to this report. [I , i I Total Site Area: The total site consists of 10.62 acres. The net area of this site, less County road right-of-way, is 8.99 acres. Ii : I I II i I , , I I Current Circumstances: The following analysis summarizes the proposed plan and its compliance with Zoning and Subdivision Ordinance requirements. Topol!raphy: This site has a varied topography, with elevations ranging from 940' MSL at its highest point to 904' MSL at the lowest point (the ordinary high water elevation of Prior Lake). The property generally drains toward the existing drainageway at the center of the site, and then to Prior Lake. Wetlands: The original plan did not identify any inventoried wetlands located within this site. Subsequently, a new inventory of the site identified a wetland located generally in the center of the parcel, and running the entire length of the parcel. The design calls for filling 4,830 square feet of the wetland. Mitigation is accomplished through off-site wetland banking credits. This proposal is consistent with the requirements of the Wetland Conservation Act (WCA) and was approved by the City Council on September 2, 2003. I I I I 'I 'I \: li II II I Ii Vel!etation: Originally, there were five single family homes located on this site; three of those homes have since been removed. There are also several stands of significant trees on this site. The project is subject to the Tree Preservation requirements of the Zoning Ordinance. 1:\03 files\03 subdivisions\03 prelim plat\03 crystal bay\cc report.doc Page 2 Access: Access to the site is from CSAH 82 on the north side of the site and Fremont Avenue on the west side of the property. CSAH 82 is classified as an arterial street in the Comprehensive Plan transportation plan, and is expected to carry between 12,500 and 14,500 trips per day by 2020. In 2002, the traffic count on CSAH 82 was 9,800 trips per day. Fremont Avenue is classified as a minor collector street and is expected to carry up to 4,000 trips per day by 2020. The 2002 traffic on Fremont Avenue was 2,350 average daily trips. I Ii " H " I' I' 2020 Comprehensive Plan Desi2nation: This property is designated for Urban Low to Medium Density Residential uses on the 2020 Comprehensive Plan Land Use Map. The entire site is located within the current MUSA boundary. Zonin2: The site is zoned R-1 (Low Density Residential). The applicant is not requesting a rezoning as part of this application. The R-1 district permits a maximum density of3.6 units per acre. Shoreland: This property is also located within the Shoreland District for Prior Lake. As such, the property is subject to the Shore land PUD requirements listed in Section 1104 of the Zoning Ordinance. Parcels utilizing the PUD process in the Shoreland District must be divided into tiers. The tiers are created by drawing lines parallel to the ordinary high water elevation (OHW). Tier I is the area within 200' of the OHW; tier 2 is the area 267' from tier I. PROPOSED PLAN: Lots: The preliminary plat consists of24 lots for the townhouse units and one lot for the common open space. Streets: This plan proposes two private streets. The first street is Drake Circle, which extends approximately 250' from CSAH 82 to the south. The access is located across from Fox Tail Trail, at the approximate location of the existing Drake Avenue intersection. This street provides direct access to 12 of the townhouse units. Crystal Bay Lane is the access onto Fremont Avenue and is located 250' south of the intersection of the intersection of Fremont Avenue and CSAH 82. It is a 300" long cul-de-sac providing direct access to 8 of the townhouse units located on the west side of the property. There is a 250' long drive off the end of this cul-de-sac, providing access to 4 of the units. The proposed private streets are designed with a 24' wide surface. The setbacks from the curb to the street will accommodate the required easements. The streets are platted as an outlot. The width of the 1:\03 files\03 subdivisions\03 prelim plat\03 crystal bay\cc report.doc Page 3 proposed streets was approved as part of the original preliminary plat and preliminary PUD. The plat also dedicates 75' of right-of-way for CSAH 82 along the north side of the plat. This additional right-of-way will be utilized for future upgrades to CSAH 82, scheduled for construction in 2004-2005. Fremont Avenue at this location also requires upgrading. The road section is currently without curb and gutter. As a condition of approval of this preliminary plat, the developer should upgrade this section as part of this project. The City would financially participate in this project. Sidewalksffrails: No public sidewalks or trails are proposed as part of this project. There is a crushed limestone trail meandering through the common area of the site. This trail is intended for the private use of the residents for access to the lake and to the common area. Parks: This plan does not dedicate any parkland. Section 1004.1000 of the Subdivision Ordinance requires 10% of the net area of the site for parkland dedication. A cash dedication in lieu of land is also possible, at the discretion of the City. The amount of park dedication at this location is very small; in addition, there is a park on the north side of CSAH 82 and on the west side of Fremont Avenue. Staff recommends a cash dedication of $2,670.00 per unit in lieu of land. This amount is greater than the amount originally identified. This is due to a change in the parkland dedication requirements since the original preliminary plat approval. Since the developers have submitted a new application, the current requirements apply. Sanitary SewerlWater Mains: Sanitary sewer and water mains will be extended from the existing utilities located in CSAH 82 and in the Glynwater development to the west. The sewer line is extended along the right-of-way. Storm Sewer: The plan proposes a NURP pond at the southwest side of the site to handle the storm water runoff. Grading on the site will also direct most run off to this pond. The City and the Prior LakelSpring Lake Watershed District have reviewed this plan. Density: The development proposes 24 townhouse units. Density for this development is not only based on the R-I district maximum allowed density of3.6 units per acre, but also on the Shoreland District requirements. The following table compares the proposed density with the permitted density. 1:103 filesl03 subdivisionsl03 prelim platl03 crystal baylcc report.doc Page 4 Permitted Proposed Density Density R-1 31 units 24 units Shoreland District Tier 1 Base Density 14 units 20 units With Multiplier 21 units Shoreland District Tier 2 Base Density 12 units 4 units With Multiplier 36 units The density multipliers in the Shoreland District are permitted only if the structure setback from the OHW is increased by 50% over the required setback. To apply this multiplier, the structure setback must be at least 112.5' from the OHW. The proposal meets this requirement. Buildinl! Styles: One of the significant changes in the proposal is the type of units. The proposed townhouses are a 3-story walkout, attached single family style dwelling with an attached garage. Each of the units in these buildings includes a 3-car garage, rear yard decks, and approximately 4,610 square feet of floor area. The buildings are 34' high at the front, with exteriors consisting of a combination of brick and stucco. Building elevations and floor plans are attached to this report. The height of the proposed buildings may also be an issue. The maximum building height is 35 feet. Building height is measured as follows: A distance to be measured from the mean curb level along the front lot line or from the finished grade level for all that portion of the structure having frontage on a public right-of-way whichever is higher to the top of the parapet or rooftop equipment, whichever is higher, of a flat roof, to the deck line of a mansard roof, to a point on the roof directly above the highest wall of a shed roof; to the uppermost point on a round or other arch type roof; or the mean distance of the highest gable on a pitched or hip roof According to the plans, the height of the structure will not exceed 35' along the private streets; however, if walkouts are utilized, the height may exceed 35' for the units adjacent to CSAH 82 and Fremont Avenue. The developer has not provided scaled elevations for the rear of the building to allow staff to determine whether or not the buildings will exceed this requirement. 1:103 filesl03 subdivisionsl03 prelim platl03 crystal baylee report.doe Page 5 Setbacks: The required and proposed setbacks for this development are shown on the following table: Setback Required Proposed Front (from private street) 25' 20' Side Street CSAH 82 25' 25' Fremont Avenue 25' IS' Side (between buildings) 15' 15' (Yz the sum of the building heights) Lakeshore (OHW) 75' 112.5' The developer is requesting a modification to the front and side street setbacks. Modifications may be approved by the City Council through the PUD process. Lot Coveraee: The R-I district allows a maximum ground floor area of 0.30. The ground floor area proposed in this plan is 0.23. Impervious Surface: The maximum impervious surface allowed in the Shoreland District is 30% of the lot area above the OHW. In this case, 30% of the lot area is 2.7 acres. Impervious surface coverage is further limited to 25% of each tier area in a Shoreland District PUD. In this case, 1.26 acres of impervious surface is allowed in tier I, and 1.23 acres is allowed in tier 2. The Planning Commission and the City Council approved a modification for the impervious surface requirements in each tier for two reasons. First of all, the applicant is dedicating more right-of-way than would normally be required because of the adjacent County road. Second, the applicant will be using pervious pavers for the driveways to reduce the impact of the impervious surface on the site. With this application, the applicant is requesting a greater modification to the impervious surface requirements. The table below compares the two plans: Permitted Approved Proposed Tier 1 25% 25% 25% Tier 2 25% 30.4% 32.1% Overall 30% 27.2% 27.9% The change in the plan appears to be a result in the shift in some of the building locations and the size of the buildings. 1:103 filesl03 subdivisionsl03 prelim platl03 crystal baylcc report.doc Page 6 A condition of approval of this modification required that the City approve the design and installation of the penneable pavement driveways. In addition, the homeowner's association documents must address the maintenance of the permeable pavement. The staff has been working with the developer on the proper design and language to address these conditions. Useable Open Space: The R-1 district also requires 600 square feet of use able open space per unit for cluster developments. Although this proposal is a PUD, it must also comply with that requirement. The required open space for this development is 15,600 square feet; the plan indicates a total of 15,875 square feet. Shoreland Open Space Requirements: The Shoreland ordinance requires at least 50% of the total project area within a PUD be preserved as open space. The common lot for this development meets the 50% requirement. The Shore land PUD ordinance also requires that 70% of the shore impact zone (50% of the setback from the OHW) be preserved in its natural state. The Shore Impact Zone on this site includes 58,433 square feet. The preserved area is 40,992 square feet or 70.2%, which is consistent with the ordinance requirement. Shore Recreation Facilities: Section 1104.805 (4,c) states the following: Shore recreation facilities, including but not limited to swimming areas, docks, and watercraft mooring areas and launching ramps, shall be centralized and located in areas suitable for them. Evaluation of suitability shall include consideration of land slope, water depth, vegetation, soils, depth to ground water and bedrock, or other relevant factors. The number of spaces provided for continuous beaching, mooring, or docking of watercraft shall not exceed one for each allowable dwelling unit or site in the first tier (notwithstanding existing mooring sites in an existing commercially used harbor). Launching ramp facilities, including a small dock for loading and unloading equipment, may be provided for use by occupants of dwelling units or sites located in other tiers. The developer development. requirements. is proposing to install 21 boat slips to serve this This is consistent with the Shoreland District Parkin!!:: The proposal provides at least 3 spaces per dwelling unit, in that each unit will have a 3-car garage; the Zoning Ordinance requires 1:103 filesl03 subdivisionsl03 prelim platl03 crystal baylcc report.doc Page 7 Landscapinl!: Section 1107.1900 lists the landscaping requirements for this development. Perimeter landscaping is required for the townhouse portion of the development with buildings consisting of 3 or more units at a rate of I tree per unit or 1 tree per 40' feet of perimeter, whichever is greater. Our calculations indicate a total of 73 trees are required for this site. The landscaping plan submitted includes 73 trees, but the sizes and types of the trees must be slightly modified to meet all ordinance requirements. This includes the requirements that at least 25% of the landscaping trees be deciduous, and 25% be coniferous, and that at least 20% of the plants must exceed the minimum sizes of 2 1/2 caliper inches for deciduous and 6' for coniferous. This requires that at least 20% of the deciduous trees be 3 y, caliper inches, and at least 20% of the evergreens must be at least 8' high. The plan also does not indicate whether an irrigation system will be provided. j! I I. il J I i I Ii I' " , I I i I a minimum of 2 spaces per unit. No parking will be permitted on the private streets. The landscaping plan also includes a 6' wood fence along the east property boundary. This was a requirement of the approval of the original preliminary plan. Tree Replacement: The applicant has submitted an inventory identifying 4,230 caliper inches of significant trees on the site. The Zoning Ordinance allows up to 25% of the significant caliper inches to be removed for road and utility purposes, and up to 25% for building pads and driveways. According to the proposed plan, 41.7% of the caliper inches will be removed for road and utility purposes and 18.3% will be removed for building pads and driveways. This requires replacement of 142 (2 Y, caliper inch) trees. Upon review of the plan, the staff feels some trees are being removed that should be retained, especially those located behind units 3 and 4. A revised grading plan has been submitted that seems to preserve these trees. The tree inventory and replacement plan must be revised to match the new grading plan. Sh~ns: There are two subdivision signs identified on the plan, one at each street entrance. No plans or elevations have been submitted for the signs. Liehtine: Street lights will be provided on the private streets. Traffic Impact Report: The developer has submitted an elementary traffic study for this development. This study indicates the proposed development will generate a total of 172 daily trips. The report assumes that approximately half of these trips will use Fremont 1:103 filesl03 subdivisionsl03 prelim platl03 crystal baylcc report.doc Page 8 A venue, and half will use CSAH 82, which is a fair assumption. The additional trips onto Fremont and CSAH 82 are a small fraction of the existing traffic on these streets. The report concludes the additional trips will not have a significant impact on the existing streets. I. , 11 I Phasin2: The developer proposes to construct this project in 2 phases. The first phase will consist of the 12 units located on the east side of the site. The second phase will consist of the cul-de-sac off of Fremont Avenue and the remaining 12 units. No time1ine has been submitted for this phasing. THE ISSUES: There are two separate applications included in this proposal. I r I PUD PRELIMINARY PLAN: The PUD must be reviewed based on the criteria found in Section 1106.100 and 1106.300 of the Zoning Ordinance. Section 1106.100 discusses the purpose of a PUD. These criteria are discussed below. (1) Greater utilization of new technologies in building design, materials, construction and land development. The developer has attempted to design the buildings so they fit the land, rather than force the land to fit the building design. The use of permeable pavement for the driveways on the site will reduce the runoff and allow further treatment of the storm water. (2) Higher standards of site and building design. The density of this site is clustered to the north and set back further from the lake shore than would be required under a conventional development. The units have also been placed so as to preserve the trees on the east boundary of the site. The utilization of private streets further reduces the impervious surface on the site. (3) More efficient and effective use of streets, utilities, and public facilities to support high quality land use development at a lesser cost. Maintenance of private streets, including plowing and future repairs, is done by the homeowners association. This reduces City costs in providing services to these homes. (4) Enhanced incorporation of recreational, public and open space components in the development which may be made more useable and be more suitably located than would otherwise be provided under conventional development procedures. The developer is providing a private beach and recreation area for the residents ofthe development, as well as private walking trails. These trails will connect to the public trail along CSAH 82. 1:\03 files\03 subdivisions\03 prelim plat\03 crystal bay\cc report.doc Page 9 (5) Provides a flexible approach to development which allows modifications to the strict application of regulations within the various Use Districts that are in harmony with the purpose and intent of the City's Comprehensive Plan and Zoning Ordinance. The density and variety of housing units is consistent with the Comprehensive Plan goals to provide a variety of housing styles. (6) Encourages a more creative and efficient use of land. The PUD allows the higher density areas to be clustered, and preserves open space. (7) Preserves and enhances desirable site characteristics including flora and fauna, scenic views, screening and buffering, and access. The townhouse units are sited to take advantage of the natural terrain. (8) Allows the development to operate in concert with a Redevelopment Plan in certain areas of the City and to insure the redevelopment goals and objectives within the Redevelopment District will be achieved. This criterion is not applicable. (9) Provides for flexibility in design and construction of the development in cases where large tracts of land are under single ownership or control and where the users) has the potential to significantly affect adjacent or nearby properties. The use of the PUD allows the clustering of the homes and the use of private streets. (10) Encourages the developer to convey property to the public, over and above required dedications, by allowing a portion of the density to be transferred to other parts of the site. There is no additional parkland dedication with this plan. Section 1106.300 states the quality of building and site design proposed by the PUD will enhance the aesthetics ofthe site and implement relevant goals and policies of the Comprehensive Plan. In addition, the following criteria shall be satisfied: (1) The design shall consider the whole of the project and shall create a unified environment within the boundaries of the project by insuring architectural compatibility of all structures, efficient vehicular and pedestrian circulation, aesthetically pleasing landscape and site features, and efficient use and design of utilities. 1:\03 files\03 subdivisions\03 prelim plat\03 crystal bay\cc report.doc Page to The design creates a unified environment. Revision of the landscaping plan to meet the requirements of the Zoning Ordinance will also enhance this area. (2) The design of a PUD shall optimize compatibility between the project and surrounding land uses, both existing and proposed and shall minimize the potential adverse impacts of the PUD on surrounding land uses and the potential adverse effects of the surrounding land uses on the PUD. The use of the PUD will allow the clustering of the townhouse units and provide a greater setback from the shore line. (3) If a project for which PUD treatment has been requested involves construction over a period of time in two or more phases, the applicant shall demonstrate that each phase is capable of addressing and meeting each of the criteria independent of the other phases. This project will be completed in two phases. The utilities, roads and landscaping will be completed for each phase. (4) Approval of a PUD may permit the placement of more than one building on a lot. This is not applicable. (5) A PUD in a Residential Use District shall conform to the requirements of that Use District unless modified by the following or other provisions of this Ordinance. a. The tract of land for which a project is proposed shall have not less than 200 feet offrontage on a public right-ofway. b. No building shall be nearer than its building height to any property line when the property abutting the subject property is in an "R-l" or "R-2" Use District. c. No building within the project shall be nearer to another building than Y, the sum of the building heights of the two buildings, except for parking ramps which may be directly connected to another building. d. Private roadways within the project site may not be used in calculating required off-street parking spaces. The modifications requested by the developer include the following: . The use of private streets. Normally, a development of this type would require a minimum right-of-way width of 50' and a 28' to 30' wide surface. The developer is requesting a 24' wide private street. The additional 26' of right-of-way would be accommodated by the use of easements adjacent to the private road. 1:103 filesl03 subdivisionsl03 prelim platl03 crystal baylcc report.doc Page tl . Reduced front yard setbacks on the private streets. The conventional setback requirement is 25' from the right -of- way line. The developer is requesting a 20' front yard setback, measured from the building face to the curb ofthe private street. . Reduced front yard setback along Fremont Avenue. The conventional setback requirement is 25' from the right-of- way line. The developer is requesting a 15' setback along Fremont Avenue.! . Impervious Surface. The developer is requesting a modification to the maximum 25% impervious surface in tier 2 of the development. The developer is proposing to utilize permeable pavement for all of the driveways in the development. This pavement, if installed and maintain properly, should reduce the impact of the impervious surface on the site. The overall impervious surface ofthe site is 27.9 percent. These modifications are permitted under the PUD provisions at the discretion of the Council. The Planning Commission found these modifications to be consistent with the goals and intent of the PUD criteria in that they allowed the clustering of the townhouses to preserve the natural terrain. The Planning Commission also found the modification to the impervious surface appropriate since the overall impervious surface is less than 30% and the ponding is sized to accommodate all of the driveways, roads, and other areas. The Commission also reasoned that a conventional development could include impervious surface up to the 30% maximum. PRELIMINARY PLAT: The preliminary plat generally meets the requirements of the Zoning and Subdivision Ordinances. If the PUD plan is approved, the preliminary plat may also be approved. There are remaining Engineering issues that must be addressed. These are basically design issues that can be addressed at the final plat stage. CONCLUSION: The Planning Commission and staff recommended approval of both the preliminary PUD plan and the preliminary plat, subject to the following conditions. 1. The tree inventory must be revised so it is consistent with the revised grading plan. 2. The landscaping plan should be revised to meet all ordinance requirements. Replacement trees must be included on the landscaping plan. 1:103 filesl03 subdivisionsl03 prelim p1atl03 crystal baylcc report.doc Page 12 FISCAL IMPACT: ALTERNATIVES: 3. The private streets must be platted as outIots. A 13' wide drainage and utility easements must be provided on either side of the outlot. The developer must place "No Parking" signs on the private streets. 4. The developer must provide easements for the storm water pond. 5. All driveways in the development must be constructed with permeable pavement. The design and installation of these drives must be approved and inspected by the City. 6. Fremont Avenue must be improved adjacent to this site. The City will participate in the cost of the project. 7. The homeowners' association documents must address the maintenance ofthe permeable pavement. 8. Address the comments identified in the memorandum from Larry Poppler, Assistant City Engineer, dated July 23, 2003.All public improvements must be constructed to the standards of the Public Works Design Manual. Revised plans must be submitted for review by the City. 9. Provide a phasing plan for the project. 10. The height of the units on Lots 23 and 24 may not exceed 35' along Fremont Avenue or CSAH 82. II. Provide plans for the entry monument signs. These signs must be located at least 10' from any right-of-way line and may not be located within the clear view triangle. Budl!et Impact: There is no budget impact as a result of this action. Approval ofthe project will facilitate the development of the area and increase the City tax base. The City Council has three alternatives: I. Adopt a resolution approving the PUD Preliminary Plan subject to the listed conditions, and adopt a resolution approving the Preliminary Plat for this development subject to the listed conditions, with the finding that the preliminary plat is consistent with the intent and purpose of the Zoning and Subdivision Ordinances. 2. Deny the PUD Preliminary Plan, and the Preliminary Plat on the basis they are inconsistent with the purpose and intent of the Zoning and Subdivision Ordinances and/or the Comprehensive Plan. In this case, the Council should direct the staff to prepare a resolution with findings of fact based in the record for the denial of these requests. 1:103 filesl03 subdivisionsl03 prelim platl03 crystal baylcc report.doc Page 13 RECOMMENDED MOTION: REVIEWED BY: 3.

Prior Lake, MN 55372-1714 I I I I: :1 II , PLANNED UNIT DEVELOPMENT PRELIMINARY PLAN RESOLUTION 03-XX RESOLUTION APPROVING THE CRYSTAL BAY PLANNED UNIT DEVELOPMENT I I MOTION BY: SECOND BY: WHEREAS: 212 Development, LLC has submitted an application for a Planned Unit Development Preliminary Plan to be known as Crystal Bay; and WHEREAS: The Prior Lake Planning Commission considered the proposed Planned Unit Development Preliminary Plan at a public hearing on September 8, 2003; and WHEREAS: Notice of the public hearing on said PUD Preliminary Plan has been duly published in accordance with the applicable Prior Lake Ordinances; and i I I WHEREAS, The Planning Commission proceeded to hear all persons interested in this issue and persons interested were afforded the opportunity to present their views and objections related to the PUD Preliminary Plan; and WHEREAS: The Prior Lake City Council considered the proposed PUD Preliminary Plan for Crystal Bay on September 15, 2003; and WHEREAS: The City Council finds the PUD Preliminary Plan is compatible with the stated purposes and intent of the Section 1106 Planned Unit Developments of the Zoning Ordinance. NOW, THEREFORE, BE IT HEREBY RESOLVED BY THE CITY COUNCIL OF PRIOR LAKE, MINNESOTA: 1. 2. The above recitals are herein fully incorporated herein as set forth above. It hereby adopts the following findings: a) Greater utilization of new technologies in building design, materials, construction and land development. The developer has attempted to design the buildings so they fit the land, rather than force the land to fit the building design. The use of permeable pavement for the driveways on the site will reduce the runoff and allow further treatment of the storm water. b) Higher standards of site and building design. The density of this site is clustered to the north and set back further from the lake shore than would be required under a conventional development. The units have also been placed so as to preserve the trees on the east boundary of the site. The utilization of private streets further reduces the impervious surface on the site. c) More efficient and effective use of streets, utilities, and public facilities to support high quality land use development at a lesser cost. , , I 1:\03 files\03 subdivisions\03 prelim plat\03 crystal bay\pudres.doc oty f . I k WVJ\.V.Cl 0 pnor a e.com PAGEl Phone 952.447.4230 / Fax 952.447.4245 Maintenance of private streets, including plowing and future repairs, is done by the homeowners association. This reduces City costs in providing services to these homes. d) Enhanced incorporation of recreational, public and open space components in the development which may be made more useable and be more suitably located than would otherwise be provided under conventional development procedures. The developer is providing a private beach and recreation area for the residents of the development, as well as private walking trails. These trails will connect to the public trail along CSAH 82. e) Provides a flexible approach to development which allows modifications to the strict application of regulations within the various Use Districts that are in harmony with the purpose and intent of the City's Comprehensive Plan and Zoning Ordinance. The density and variety of housing units is consistent with the Comprehensive Plan goals to provide a variety of housing styles. f) Encourages a more creative and efficient use of land. The PUD allows the higher density areas to be clustered, and preserves open space. g) Preserves and enhances desirable site characteristics including flora and fauna, scenic views, screening and buffering, and access. The townhouse units are sited to take advantage of the natural terrain. h) Allows the development to operate in concert with a Redevelopment Plan in certain areas of the City and to insure the redevelopment goals and objectives within the Redevelopment District will be achieved. This criterion is not applicable. i) Provides for flexibility in design and construction of the development in cases where large tracts of land are under single ownership or control and where the users) has the potential to significantly affect adjacent or nearby properties. The use of the PUD allows the clustering of the homes and the use of private streets. j) Encourages the developer to convey property to the public, over and above required dedications, by allowing a portion of the density to be transferred to other parts of the site. There is no additional parkland dedication with this plan. k) The design shall consider the whole of the project and shall create a unified environment within the boundaries of the project by insuring architectural compatibility of all structures, efficient vehicular and pedestrian circulation, aesthetically pleasing landscape and site features, and efficient use and design of utilities. The design creates a unified environment. Revision of the landscaping plan to meet the requirements of the Zoning Ordinance will also enhance this area. I} The design of a PUD shall optimize compatibility between the project and surrounding land uses, both existing and proposed and shall minimize the potential adverse impacts of the PUD on surrounding land uses and the potential adverse effects of the surrounding land uses on the PUD. The use of the PUD will allow the clustering of the townhouse units and provide a greater setback from the shore line. m) If a project for which PUD treatment has been requested involves construction over a period of time in two or more phases, the applicant shall demonstrate that each phase is capable of addressing and meeting each of the criteria independent of the other phases. 1:\03 files\03 subdivisions\03 prelim plat\03 crystal bay\pudres.doc PAGE 2 This project will be completed in two phases. The utilities, roads and landscaping will be completed for each phase. n) Approval of a PUD may permit the placement of more than one building on a lot. This is not applicable. 0) A PUD in a Residential Use District shall conform to the requirements of that Use District unless modified by the following or other provisions of this Ordinance. 1) The tract of land for which a project is proposed shall have not less than 200 feet of frontage on a public right-of-way; 2) No building shall be nearer than its building height to any property line when the property abutting the subject property is in an "R-1" or "R-2" Use District; 3) No building within the project shall be nearer to another building than Y, the sum of the building heights of the two buildings, except for parking ramps which may be directly connected to another building; and 4) Private roadways within the project site may not be used in calculating required off-street parking spaces. The modifications requested by the developer include the following: . The use of private streets. Normally, a development of this type would require a minimum right-of-way width of 50' and a 28' to 30' wide surface. The developer is requesting a 24' wide private street. The additional 26' of right-of-way would be accommodated by the use of easements adjacent to the private road. . Reduced front yard setbacks on the private streets. The conventional setback requirement is 25' from the right-of-way line. The developer is requesting a 20' front yard setback, measured from the building face to the curb of the private street. . Reduced front yard setback along Fremont Avenue. The conventional setback requirement is 25' from the right-of-way line. The developer is requesting a 15' setback along Fremont Avenue.! . Impervious Surface. The developer is requesting a modification to the maximum 25% impervious surface in tier 2 of the development. The developer is proposing to utilize permeable pavement for all of the driveways in the development. This pavement, if installed and maintain properly, should reduce the impact of the impervious surface on the site. The overall impervious surface of the site is 27.9 percent. These modifications are permitted under the PUD provisions at the discretion of the Council. The City Council found these modifications to be consistent with the goals and intent of the PUD criteria in that they allowed the clustering of the townhouses to preserve the natural terrain. The Council also found the modification to the impervious surface appropriate since the overall impervious surface is less than 30% and the ponding is sized to accommodate all of the driveways, roads, and other areas. The Commission also reasoned that a conventional development could include impervious surface up to the 30% maximum. 3. The Crystal Bay Planned Unit Development Preliminary Plan is hereby approved subject to the following conditions a) The tree inventory must be revised so it is consistent with the revised grading plan. b) The landscaping plan should be revised to meet all ordinance requirements. Replacement trees must be included on the landscaping plan. c) The private streets must be platted as outlots. A 13' wide drainage and utility easements must be provided on either side of the outlot. The developer must place "No Parking" signs on the private streets. d) The developer must provide easements for the storm water pond. 1:\03 files\03 subdivisions\03 prelim plat\03 crystal bay\pudres.doc PAGE 3 e) All driveways in the development must be constructed with permeable pavement. The design and installation of these drives must be approved and inspected by the City. f) Fremont Avenue must be improved adjacent to this site. The City will participate in the cost of the project. g) The homeowners' association documents must address the maintenance of the permeable pavement. h) Address the comments identified in the memorandum from Larry Poppler, Assistant City Engineer, dated July 23, 2003.AII public improvements must be constructed to the standards of the Public Works Design Manual. Revised plans must be submitted for review by the City. i) Provide a phasing plan for the project. j) The height of the units on Lots 23 and 24 may not exceed 35' along Fremont Avenue or CSAH 82. k} Provide plans for the entry monument signs. These signs must be located at least 10' from any right-of-way line and may not be located within the clear view triangle. Passed and adopted this 15th day of September, 2003.

Case #03-98 & 03-99 212 Development has submitted an application for a townhouse development known as Crystal Bay Townhomes consisting of 24 units on 10.62 acres ofIand zoned R-ISD. The property is located on the south side ofCSAH 82, east of Fremont Avenue and Y, mile west ofCSAH 21. This application is a revised proposal to the previously approved preliminary plat and preliminary PUD plan. Planning Coordinator Jane Kansier presented the Planning Report dated September 8, 2003, on file in the office of the Planning Department. 212 Development, LLC, has applied for approval of a development to be known as Crystal Bay on the property located south ofCSAR 82, directly east of Fremont Avenue and approximately Y, mile west of CSAR 21. The application includes a Planned Unit Development Preliminary Plan and a Preliminary Plat. L:\03 Files\03 Planning Comm\03pcMinutes\MN090803 .doc 1 Planning Commission Meeting September 8, 2003 The proposal calls for a townhouse development consisting of 24 dwelling units on 10.62 acres. The development also proposes private open space and 21 boat slips for the use of the residents. The City Council approved a preliminary plat and preliminary PUD plan for this development on October 7, 2002. However, when the developer submitted the final plan, there were some changes that were inconsistent to the approved preliminary plan. As a result, the developer has chosen to resubmit a preliminary plat and preliminary PUD plan application. The general provisions of the proposal have not changed. Staff recommended approval of the PUD Preliminary Plan and the Preliminary Plat subject to the following conditions: 1. The tree inventory must be revised so it is consistent with the revised grading plan. 2. The landscaping plan should be revised to meet all ordinance requirements. Replacement trees must be included on the landscaping plan. 3. The private streets must be platted as outlots. A 13' wide drainage and utility easements must be provided on either side of the outlot. 4. The developer must provide easements for the storm water pond. 5. All driveways in the development must be constructed with permeable pavement. The design and installation ofthese drives must be approved and inspected by the City. DRAFT 6. Fremont Avenue must be improved adjacent to this site. The City will participate in the cost of the project. 7. The homeowners' association documents must address the maintenance of the permeable pavement. 8. Address the comments identified in the memorandum from Larry Poppler, Assistant City Engineer, dated July 23, 2003.All public improvements must be constructed to the standards of the Public Works Design Manual. Revised plans must be submitted for review by the City. 9. Provide a phasing plan for the project. 10. The height ofthe units on Lots 23 and 24 may not exceed 35' along Fremont Avenue or CSAH 82. 11. Provide plans for the entry monument signs. These signs must be located at least 10' from any right-of-way line and may not be located within the clear view triangle. Questions from the Commissioners: Ringstad questioned how much additional dedication the developer is giving than what is normally required. Kansier said it was an additional 25 feet along the entire north boundary ofthe property which is at least a quarter mile. L:\03 Files\03 Planning Comm\03pcMinutes\MN090803.doc 2 Planning Commission Meeting September 8, 2003 Criego questioned if the 25 feet on the north side has already been dedicated. Kansier said it would be dedicated as part of the final plat. Criego questioned if the calculations included the 25 feet? Kansier responded it did include the 25 feet. Comments from the public: DRAFT John Klingelhutz said they changed the design of the building because of the land value. It wasn't in all the size of the building that changed the impervious surface. There were some mistakes made in the original calculations. It is a 7/10'h percent difference over. They feel they have a good plan and do not want to change the layout ofthe building. Atwood questioned if the 23rd and 24'h units have height problems. K.1ingelhutz said the height of units would be reduced by 10 feet if they did not make them walk-outs. Criego asked what the additional footage was added to the footprint. K.1ingelhutz responded they did not add to the footprint they added another level inside the home. Tom Finn, 15672 Fremont Avenue, was at the first presentation and felt everyone left as friends. The developer has a nice product. Finn expressed the following concerns: the value of the homes; tree removal; the dock length, the dock covenants and what would be allowed and the entrance and lighting on Fremont Avenue; Kansier pointed out the proposed access off Fremont is 250 feet from the CSAH 82 intersection. She went on to explain that generally the homeowner's documents are not reviewed by the City for specific requirements. Staff looks at the general provisions and how they coincide with the City regulations. Kansier said the developer would take care oflighting for the development. The City would be involved in any public street issues and lighting could be part of the County Road 82 project in 2004. Bill Rudnicki, 2330 Sioux Trail NW, stated he has known the developer for over 10 years and wanted the public to know the developer is concerned with the neighbors' issues and this will be a first class development. Tom Sheele, 15601 Highland Avenue, had a number of questions and concerns: the acreage difference from the first proposal to the second proposal. What numbers were used in the density calculations? Kansier explained the calculations and what was excluded. Sheele felt the PUD regulations had to be 10 acres. Kansier said the gross acreage is over 10 acres. Sheele asked to look at the landscaping plans. He went on to question the traffic study. Kansier said it was public information and he would be welcome to come and review. Shee1e questioned the vegetation regulations. Sheele also felt the developer does not meet the PUD requirements as there is no general benefit to the community. L\03 Files\03 Planning Comm\03pcMinutes\MN090803.doc 3 Planning Commission Meeting September 8. 2003 Kyle Schroeder, 15557 Highland Avenue, questioned the tree removal. Schroeder presented photos ofthe area and questioned ifthe trees were going to be removed. He would like the developer to come out and mark the trees. Schroeder said he did not understand why the pavers had to be tested so close to the lake. Maintenance should be in the covenants. Schroeder went on to explain his experience with homeowner associations. Stamson responded maintenance would be part of the PUD process. Schroeder would like to know who is going to inspect the pavers. Stamson said it was a simple procedure. Kansier pointed out Schroeder's property and where the significant trees lay on the development. Schroeder asked for an explanation on the impervious surface. Stamson responded. Schroeder said the paver issue is a concern. Stamson explained the pavers were being treated as though they were concrete. They are not getting a credit for impervious. Schroeder stated he would like to see the developer provide a noise barrier. Kendall Larson, representative for the impervious pavers the developer will be installing addressed the issues brought up by the public. In reference to Schroeder's comments that the pavers have never been tested - Larson pointed out the Minnesota Landscape Arboretum tested and monitored this product with other products. There are numerous projects around the State and Twin Cities who have used the pavers and have been successful. Criego questioned the percentage of runoff versus permeating the pavers. Larson said he can not give an exact amount but he explained the paver opening is 13% of the brick. He said he is not an engineer and is not able to address the question. The engineer was not able to make the meeting. The public hearing was closed. DRAfT Comments from the Commissioners: Criego: . There are several ways of addressing the noise abatement on County Road 82. There are a number oftrees along County Road 82. Kansier responded a significant number of evergreen trees will be planted along the right-of-way for screening and some noise abatement. Hoped the applicant would try to address that issue and reduce the noise. . Surprised the neighbors have not spoke on the height of the buildings. It is within the regulations. It went from a two-story to a three-story complex. . The additional square footage being requested is .7%. The overall concern is 30% on the property, not the 25% on the tiers. From a lake preservation standpoint this is not a major issue. It is well under 30%. The drainage goes to the sides. L:\03 Files\03 Planning Comm\03pcMinutes\MN090803.doc 4 Planning Commission Meeting September 8, 2003 " I' II ,I ! Lemke: . Was skeptical at first for any increase on impervious surface but after hearing Criego and remembering Tier 2 does not run into the lake that a lot of this surface is mitigated by the use of materials. . Everything is really the same and there have been improvements. . The dockage issue was covered a year ago and the number of docks is the same. . It is a worthwhile project that meets all requirements. Supported. I I ij I' 1! I' ,I I I Atwood: . Agreed with the Commissioners. The covenants and noise abatement issues have been addressed. . Suggested a neighborhood meeting where something could be presented including the landscape and covenants. It doesn't need the neighbors' stamp of approval but they could see the efforts by the developer. . All the information is public. . Agreed with the Commissioners on the impervious surface. It is not an issue. . There has to be a second access to the development. . Support. Ringstad: . This was a good process - a year ago there were negotiations between the developer and the neighbors. There are a lot of positive comments. . A little disappointed we are looking at this again tonight. The neighbors are bringing up issues addressed a year ago. . Surprised the height of the buildings were not brought up by the neighbors but they are within the code. . Agreed with Commissioners on the impervious surface issue especially with the drainage moving away from the lake. · Okay with the development. DR AFT Stamson: . The two big changes are the design of the building, although it meets regulations and the second is a minor calculation error on the impervious surface. Generally the Commission is looking at single lots, this development as a whole is under the 30% requirement The tier discrepancies are further back and drain away from the lake. . The County Highway requirements pushed the driveways into Tier 2. There was no credit given to the pavers. . Comfortable with this project - will support. . There is a number of ways to mitigate noise. Landscaping is a very efficient way of mitigating noise. Residents can also take care of their own properties. Noise walls work well for adjacent property owners but as you get away from them the wall is not effective. Noise increases from bouncing off walls. You cannot lump this on a single developer when hundreds of cars are coming from other places. . Homeowners should take it upon themselves to handle the noise. I ,I II I I , I i I I II " il t!

One of the speakers made the comment that the road dedication is required under law. If no one was buying this land, the County would have to come in and buy this land. Kansier responded that was correct, the County would normally have to buy the 25 feet of right-of-way. Dedicating the right-of-way would not be required. Criego: . Asked the applicant the price range. Klingelhutz responded the units would start at $850,000 to a 1.1 Million. Association fees will be around $350.00 a month. . Kingelhutz said they looked at the noise abatement issue. They are concerned and will do the best they can to address the noise - that is why the landscape plan has a lot of trees. It is in our best interest. . Klingelhutz did not send out the notices for a neighborhood meeting in time. . Regarding the homeowner's association - they might have to put up money first so the City is assured the driveway maintenance is done. . Klingelhutz said there are no buildings in Tier 2 - only driveways. . Asked if the developer knows where the dredged area of the lake is. Klingelhutz responded he did not know and would research the matter. , I II I' !I , MOTION BY RINGSTAD, SECOND BY ATWOOD, RECOMMENDING APPROVAL OF A PLANNED UNIT DEVELOPMENT PRELIMINARY PLAN AND PRELIMINARY PLAT TO BE KNOWN AS CRYSTAL BAY SUBJECT TO THE 11 CONDITIONS IN THE STAFF REPORT.

August 14,2003 Ms. Jane Kansier, AICP City of Prior Lake Planning Department 16200 Eagle Creek Ave SE Prior Lake, MN 55372 RE: CRYSTAL BAY TOWNHOMES City Job No. 02-34 Otto Job No. 2-03-0122 Dear Ms. Kansier: The purpose of a General Development Plan and Planned Unit Development is to redevelop the existing 10.62 acre site by developing 24 town homes along a 24' private street with scenic views of the Upper Prior Lake Bay. The PUD includes 21 boat slips. We are seeking a PUD on this property in order to provide for a unique townhome development, which includes many walkout style units and front-loaded garages. The flexibility of the PUD process will allow the units to be placed in the most efficient layout that maximize views of the lake while still maintaining the character of the site. The following public benefits include: 1. A higher standard of site design was needed to layout the town home units that maximizes views of the lake while still preserving as much of the natural character of the site as possible. The building design of the town home also meets a higher standard of design by the use of an efficient floor plan and an eye for quality details. 2. The plan emphasizes the use of common open space, which nearly envelops the development. The green space is particularly important where the stands of trees are preserved along the east property line and along the entire shoreline. This allows everyone easy access to the lake. A trail system for the development is also available to all residents from the common open space areas. 9 WEST DIVISION STREET. BUFFALO, MN 55313 . (763) 682-4727 . FAX (763) 682-3522 Letter to Jane Kansier City of Prior Lake Crystal Bay Townhomes Page - 2 3. The use of walkout style townhomes in areas that work with the topography and full-basement units in areas of level terrain minimizes the need for grading. 4. The preservation of many of the existing trees along the eastern part of the site allows the natural character to remain and provides a buffer from the neighborhood to the east. Modifications from the existing district regulations include the following: The proposed side street yard setback is 15'. Typical side street yard setbacks in an R-1 district are 25'. In an effort to create efficient use of the property, it was necessary to narrow the side street yard setback to 15'-0". This distance would allow for landscaping between the unit and future sidewalks that would buffer the unit from the street. Phasinq Phase I consists of 12 units on approximately 7.22 acres and the construction of a detention pond. Phase II consists of 12 units on approximately 3.40 acres and the construction of a detention pond. This phase will complete the project and the connection of Crystal Bay Drive to Fremont Avenue Northwest. Densitv Calculations Tier 1 Density = 5.24 Acres/20 Units = 3.82 Units Per Acre Tier 2 Density = 3.74 Acres/4 Units = 1.07 Units Per Acre Ground Floor Area = 51,384 SF Floor Area Ratio = 0.23 Parkinq Each unit includes a three-car garage and three spaces per driveway.

Letter to Jane Kansier City of Prior Lake Crystal Bay Townhomes Page - 3 Zoninq R-1SD TRAFFIC ANALYSIS Introduction The Crystal Bay Development is located along Scott County Road No. 82 (154111 Street Northwest) and Fremont Avenue Northwest. The project consists of 24 townhome units in 12 tWin home style structures. Backqround Crystal Bay Development will have a direct connection to both County Road No. 82 and Fremont Avenue Northwest via a private street. The project will be developed in two phases with Phase One consisting of 12 units on the easterly one-half of the site, and 12 units for Phase Two which is the westerly one-half of the project site. Historically, the site has been used for residential purposes so the projected new trips are not entirely an increase of traffic generation. Access of the private road to both Fremont and County Road No. 82 are currently a "stop and go" situation. County Road No. 82 is a minor arterial and Fremont is classified as a local street. The employment center and school systems are primarily located to the north of the project site. Assumptions For the purpose of the traffic analysis, we have used the assumptions used in the previously approved PUD application. The assumptions made are as follows: · One trip per unit outbound for AM peak hour (24 trips) · Two-thirds trips inbound and one-third outbound for PM peak hour · 6.6 trips per day for each town home unit (158 trips per day) · 85% of outbound trips will be a right turn movement and 15% left turn It is our opinion that the total inbound movement on County Road No. 82 is insignificant compared to the total volume on County Road No. 82 and will not create significant delays. The same is true for Fremont Avenue Northwest at the intersection with County Road No. 82. Letter to Jane Kansier City of Prior Lake Crystal Bay Townhomes Page - 4 With the upgrade to County Road No. 82, a right turn lane will be constructed for vehicles turning onto Fremont Avenue. The applicant will be assessed by the county for this improvement. The applicant is also dedicating through the platting process additional right of way for the expansion of County Road No. 82. ENVIRONMENTAL ISSUES Environmental issues concerning the site include the removal of existing homes and outbuildings, the abandonment of private water wells and individual septic treatment systems, temporary and permanent erosion and sediment control and tree removal and replacement. There are no known or suspected dumps, hazardous materials or threatened or endangered species. Removal of Exist/no Homes Five single-family residential homes and various outbuildings occupied the site. One home is served by municipal sewer and water service, while the others have private wells and individual septic systems. The applicant has moved the three homes in the area proposed to be developed as Phase I and has contracted with licensed well drillers and septic operators to abandon the wells and septic systems in accordance with state statutes. Wells and septic systems will be properly abandoned on the other properties as well. The project will result in all homes being connected to municipal services and will remove the potential of septic leakage or runoff into Prior Lake. Erosion and Sediment Control The construction and development will utilize best management practices to control erosion and runoff with Prior Lake in accordance with the necessary NPDES erosion control permits. Two permanent sedimentation ponds will be constructed and will be protected by a public drainage easement. Tree Removal and Replacement The project has been designed to protect and preserve most of the trees in the shoreland, bluff impact zones and along the east property line adjoining Island View Addition. On the east side retaining walls and modified building design were employed to assure that many of the mature trees are preserved. The tree replacement was completed and calls for 312 caliper trees to be planted on the site. Many of the replacement trees are similar in species to what exists on the site (oak, maple, spruce), so the landscape character will remain consistent. Letter to Jane Kansier City of Prior Lake Crystal Bay Townhomes Shore Impact Zone Page - 5 The Shoreland PUD Ordinance requires that 70% of the shore impact (50% of the setback from the OHW) be preserved in its natural state. The area of the shore impact zone for the site is 58,433 SF. The area proposed to be preserved is 40,992 SF or 70.2%. Sincerely, Otto Associates Engineers and Land Surveyors, Inc. ~)~ Cara Schwahn Otto, P.E. CSO:jk cc: Tom Heiland, 212 Development Group 1. Due to error made in the preliminary approval, we are now at the 28% of impervious surface instead of27.2%. We have not changed anything on the building size or in the development design. We also believe that the last calculation for impervious surface should give us a 50% credit for the driveways. 2. Grade elevations were also calculated mistakenly and it moved the 904 elevation 15' closer to units 13 and 14. Therefore we cannot maintain the 112' setback from a.H.W. 9L j/ !:0 DATE: July 23,2003 TO: Jane Kansier, Planning Coordinator cc: Sue McDermott, City Engineer FROM: Larry Poppler, Assistant City Engineer RE: Crystal Bay (Project #02-34) The Engineering Department has reviewed the subject final planned unit development and has the following comments: GRADING! EROS10N CONTROL I. Grading plan continues to be cluttered and difficult to read. Revise grading plan in such a way that makes the plan easier to read. Please submit a grading plan without the tree plan showing in the foreground (gray existing features). 2. Show the pervious paver piping on the plans. Show details and calculations for the pervious pavers. Part of the reason pervious pavers were accepted by the City was because a system was to be designed for this application. The City has not yet seen the proposed design, signed by a licensed professional engineer. 3. Show details and calculations for the infiltration basin. What happened to the infiltration basin? 4. Show construction limits including trail! path grading. 5. Place the name and phone number of the person responsible for erosion and sediment control plan preparation, implementation, and maintenance on the plans. A phone number was not included on the plan sheet. 6. Submit detailed plans and specifications for the retaining walls. Submit calculations for retaining walls over 4 feet in height. 7. Show all emergency overflow routes for surface water drainage. Provide flow arrows. 8. Show or define access routes for all ponding areas (maximum of 8% grade, 2% cross slope and 10' wide). 9. The top ofbenn elevation of the ponds shall be a minimum of one foot higher than the HWL of the pond. 10. Show grading and limits for entrances to be removed. II. The erosion control notes need to include text specifying that slopes greater than 4: I shall have an erosion control blanket installed immediately after the completion of grading. These areas should be illustrated on the plan or revise grades to no more than 4: I throughout the plan. 12. Floating silt curtain should be placed along the shoreline at the storm sewer discharge points to contain any sediment that may be discharged from this site during construction. G: \PROJECTS\2002\34crystalbay\Review 3 072303.DOC WETLAND 1. As indicated in our memo dated October 25, 2003, a 30' average buffer (with a minimum of 20') from the OHW of elevation 904 must be shown on the plans in accordance with City Standards. It is unclear if the easement shown on the plat is designated for the buffer. Additionally, the area on the plat does not appear to be an average of 30 feet and portions of the area are less than the minimum 20' requirement. 2. The wetland replacement application was sent out for the required 30.day notice on July 16, 2003. The 30.day comment period will end on August 15, 2003. Work in the wetlands cannot start until this applicatlOn is approved by the City. The wetland was delineated by Kjolhaug Environmental Services and field verified by WSB. WATERMAIN I. Water services may be placed in same trench with sanitary services, however sanitary services must be three feet downstream from water services. SANITARY SEWER I. Raise lots 13 and 14 so that ejector pumps will not be necessary. 2. Add cleanouts on services longer than 100 feet. STORM SEWER I. Drainage discharge overflow is shown flowing onto the Scott County right of way ditch. 2. Revise plans to show the minimum stonn sewer pipe size of 15". 3. A "Rainstore" note is shown. Is the "Rainstore" part of the proposed project? 4. Class ill riprap, rather than Class II riprap, must be called out at the outfalls of the stonn sewer shown on Detail B and Detail D on Sheet II. This detail must be in confonnance with MnDOT Plate 3133 for volume. 5. The outlet control structure of the south pond should be redesigned to decrease the slope of the outlet pipe. An example of a possible design is attached with this memo. 6. It should be noted on the stonn sewer profiles that the last 3 joints of all storm sewer pipes shall be tied. STREET 1. CuI de sacs need to follow the detail plate #506 of the Public Works Design Manual. Show the grades and drainage arrows for the cuI de sacs (minimum grade is 0.8%). 2. 1s a boat ramp or beach access path proposed or has that been removed from the design? 3. Street lighting is to be consistent with the City's policy outlined in the Public Works Design Manual. A Street lighting plan prepared by Xcel must be submitted. 4. Show typical section for trail. 2 o Page 1 of 1 ELEV.909.

"7/'111/(\1 INTEROFFICE MEMORANDUM TO: FROM: RE: DATE: PLANNlNG/ENGlNEERlNG Ralph Teschner, Finance Director Crystal Bay. preliminary plat (assessment/fee review) August 26, 2003 A 10.62 acre parcel in 34.115.22 (PIN #259340180 thru #25934027) is proposed to be platted into Crystal Bay. This area has received no prior assessments for City municipal utilities Since utilities are available to the property site, the cost for the extension of services internally will be the responsibility of the developer. 1n addition to these improvement costs, the subdivision will be subject to the following City charges: Park Dedication Collector Street Fee Stormwater Management Fee Trunk Sewer & Water Fee $2670.00/unit $1500.00/acre $2943.00/acre $3500.00/acre The application of these City charges would generate the following costs to the developer based upon a net lot area calculation of 9.00 acres (excludes CSAH 82 ROW') of townhouse units as provided within the site data summary sheet ofthe preliminary plat. Park Dedication Fee: 24 units @ $2670/unit = $64,080.00 Collector Street Fee: 9.00 acres@ $1500.00/ac = $13,500.00 Storm Water Management Fee: 9.00 acres @ $2943.00/ac = $26,487.00 Trunk Sewer & Water Charge: 9.00 acres @ $3500.00/ac = $31,500.00 Assuming the initial net lot area of the final plat does not change, the above referenced storm water, collector street, and trunk 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. , Stormwater pond acreage has NOT been deducted. 16200 Eagle Creek Ave. S.E.. Prior Lake.
