Call to Order: Chairman Stamson called the June 24, 2002, Planning Commission meeting to order at 6:30 p.m. Those present were Commissioners Atwood, Ringstad and Stamson, Planning Coordinator Jane Kansier and Recording Secretary Connie Carlson. 2. Roll Call: Atwood Present Criego Absent Lemke Absent Ringstad Present Stamson Present 3. Approval of Minutes: The Minutes fi-om the June 10, 2002, Planning Commission meeting were approved as presented. 4. Consent: 5. Public Hearings: Commissioner Stamson read the Public Hearing Statement and opened the meeting. A. Case File #02-070 - Consider an Amendment to Section 1102.1403(6) (Gymnastic Schools in the C-5.Zoning District) of the Zoning Ordinance. Planning Coordinator Jane Kansier presented the Planning Report on file in the office of the City Planning Department. In June of 1998, the City Council adopted an amendment to the zoning ordinance permitting gymnastics schools in the C-5 (Business Park District) as conditional uses. Three conditions were included as conditions of approval. 1. The use occupies no more than 4,000 square feet in the principal structure. 2. Hours of operation are limited to 5:00PM to 11:00 PM, Mondays through Fridays, and 7:00 AM to 11:00 PM on Saturday and Sunday. 3. A minimum of one parking space per 300 square feet of floor area is provided. Subsequent to the adoption of this ordinance amendment, a conditional use permit was approved for Gleason's Gymnastics School in a building on Fish Point Road in the Business Office Park. Recently, Mr. Gleason contacted the City because his lease is up and he is looking for new space. He also indicated he needed more room and expanded hours of operation. L:~)2F1LES~02planning comm~02pcminutesWIN062402.doc Planning Commission Meeting June 24, 2002 When the original ordinance was adopted, there was considerable discussion about the appropriateness of the use in the C-5 district. The staff concluded at that time the use was not appropriate for the zoning district but the Planning Commission felt it was. The conditions that were attached were felt to be appropriate for the use. When the school was originally opened, there were complaints fi.om other tenants about parking and noise. These issues were addressed by signing parking for the school and adding sound barriers to the space occupied by the school. The school has lost its lease at the present location and has been looking at occupying 10,000 square feet in another building in the Business Park. However, due to the size limitations and hours of operation as well as problems with the TIF district on the proposed property, they have been unable to move in. Ringstad asked Kansier to expand on the initial problems with the school being located in a Tax Increment Financing (TIF) District. Kansier explained the situation and limitations on the types of permitted uses. TIF is intended for manufacturing, office and industrial uses. Uses that do not fit that criteria spelled out in the State Statutes are limited to 15% of the building. Gleason's Gymnastic School was at 15% at the previous building and not allowed any more than that. 10,000 square feet would put them over in any other building. Stamson asked if the City had an opinion on this issue. Kansier said they didn't. Whoever occupies the building and is not meeting the statutory requirements would result in the City having no choice but to de-certify. Atwood questioned the length ora TIF District. Kansier responded anywhere fi.om 9 to 11 years. Most tenants are halfway through their district. Each lot has its own district. Atwood questioned if the owner was aware of the TIF situation. Kansier said he was very aware of the potential for losing TIF. There were no comments fi.om the public. Comments from the Commissioners: Ringstad: · The gymnastic school is currently in the C5 district and currently occupying less than the 10,000 square feet they propose. Did not have a problem with this moving forward. · Decertification of the TIF District is a natural event to take place. · Support the relocation. Atwood: · Agreed, if that helps Gleason to stay in Prior Lake. · Remove restrictions on the hours of operation is a great idea. L:\02F1LES\02planning ¢omm\02perainutes\MN062402.doc 2 Planning Commission Meeting June 24, 2002 Stamson: Disagreed. When this issue was first brought forward there was a lot of discussion if this was an appropriate use for the district. The concern was compatibility with surrounding uses and safety for the kids in an industrial setting. · Initially there were a number of problems, some have been fixed. · Generally the industrial area is not compatible with a lot of children moving around in their parking lots. It makes me nervous sending so many kids around .in an industrial use area. · Another big issue was the parking with the large number of cars going in and out. · Not sure it wasn't a mistake to allow it in the first place. Some of the issues have been addressed. · Not comfortable with the expansion. · Savage has that use in their industrial park but the building is freestanding and separate from other buildings. · Atwo0d questioned who the other tenants were. Kansier responded.~ · Stamson explained the initial CUP was for a starting place and then the school would find another place to build a freestanding bnilding. That is why the condition was for 4,000 square feet. Long term the school was not to be in the C5 District. · That is also why the hours of operation were limited - to avoid being in the same joint location. · Now they are talking l0,000 sq feet. Maybe it would work in this building but in many buildings in town it would not work. It is not generally appropriate for a C5 District. Larry Gleason, of Gleason Gymnastic School, said the building he was in had some problems and were very specific. Limited parking and only one route for trucks to come in. He has two other gymnastic schools and both are in industrial districts. Gleason felt there would be more parking in the new building. He also felt the hours of operation limited him to evening hours. Most of the classes are after school. There would not be a lot of traffic during the day. Stamson: · Gleason is right that the conditions are specific to that building, but the ordinance is for the entire C5 District. Just because Gleason is moving to a bigger building does not mean the next guy would do the same. · Disagreed Gleason's problems were unique to that building. Most of the buildings in town have that problem. · It is a district-wide issue. Prior Lake does not have a lot of big indhstrial space. · Parking and traffic was a big problc~n. Atwood: · Can see where parking.was a huge problem. Having children enrolled was a problem. · This site is well suited for it. · Stamson pointed out the discussion is the district and city as a whole, not Gleason's proposal. L:~O2FILES~O2planning comm~O2peminu~es~lN062402.do¢ 3 Planning Commission Meeting June 24, 2002 · Does not see a problem with other applicants and supported. Ringstad: · Gathered in reading the report, that parking was a big concern. Parking in the new location will be much better. · His daughter was in the program a few years ago and it was a nightmare with people coming and going with no place to park. · The new building is laid out better where the parking is in front with the docks in the back. · It will be a great addition to the school itself. · Supported. Stamson: · If the size and hours are going to be relaxed, maybe tighten the parking and the amount of space where the kids are dropped off. · Kansier said it could be done but to keep in mind, this does not remove the requirement for a Conditional Use Permit. Any kind of proposal that comes in would be reviewed on a site-specific basis. Another option would be to tighten the parking. Maybe add a provision for drop-off. Or limit number of students to some function of the park. Kansier went on to explain the Conditional Use Permit could allow for some kind of annual review. Stamson: · Would like to see some of the past problems addressed up front. · Designate a drop-off to keep separate from the school and business. · Kansier said you want requirements to be general enough but could add the minimum parking with a drop-off area/pickup area designated. Atwood: · Did not feel there had to be such specific language when there is not going to be large competition. Stamson questioned Gleason on how many children are in a class. Gleason said they generally have around 8 to 9 students and sometimes with a full program going on - 3 classes. Maybe 24 to 25 kids. With this additional space, the amount of classes could double, but they would all come at different times. Kansier said there could a condition for minimum of 1 parking space per 2 students in the larger class or whatever is greater. Atwood felt it was not necessary. Ringstad said he would approve with conditions. L:\02FILES\02planning comm\02pcminutesWiN062402.doc 4 Planning Commission Meeting June 24, 2002 Kansier suggested requiring a designated drop-off and pickup area with a physical separation between pedestrian and truck loading. Then review it as part of the Conditional Use Permit. It is made aware there is a separation of traffic. MOTION BY STAMSON, SECOND BY RINGSTAD, RECOMMEND APPROVAL OF THE AMENDMENT WITH THE 3 CONDITIONS AS STATED. Vote taken indicated ayes by all. MOTION CARRIED. Kansier recapped the conditions: · The use would be limited to 10,000 square feet; · A minimum of 1 parking space per 300 feet of floor area; or 1 space per 2 students whichever is greater; and a · Designated drop-off/pickup area that physically separates pedestrian and truck loading. This item will go before the City Council on July 15, 2002. B. Case Files #02-024 and #02-025 - Consider a Planned Unit Development Preliminary Plat to be known as Timber Crest Park. The proposal includes 28.19 acres to be subdivided into 162 townhouse units located in the southeast quadrant of 'the intersection of County Road 21 and Highway 13, on the north side of Franklin Trail and Bluff Heights Trail. Planning Coordinator Jane Kansier presented the Planning Report on file in the office of the City Planning Department. Ray Brandt has applied for approval of a development to be known as Timber Crest Park on the property located at the southeast quadrant of the intersection of CSAH 21 and TH 13, on the north side of Franklin Trail and BluffHeights Trail. The property owner, Prior Lake Apartments, has also signed the application. The application includes the following requests: · Approve a Planned Unit Development Preliminary Plan; · Approve a Preliminary Plat. This property is zoned R-4 (High Density Residential). The proposal calls for a townhouse development consisting ora total of 148 dwelling units on 28.19 acres. The development also includes parkland and private open space. This original proposal involved filling a large portion of the wetland on the site. The Wetland Technical Evaluation Panel (TEP) subsequently advised the developer that the proposal was inconsistent with the Wetland Conservation Act, and could not be approved. L:\02FILES~02planning comm~02pcmin u teshMN062402 .doc 5 Planning Commission Meeting June 24. 2002 As a result of the TEP decision, the developer submitted new plans on June 11, 2002. Because of the timing of this submittal, the staff did not have the opportunity to review the new plans. In addition, the developer must submit a revised wetland mitigation plan and revised storm water drainage calculations. However, since the public hearing had already been published and notices sent, the staff had no choice but to place this item on the agenda. Staff recommended continuing this item to the July 8, 2002 meeting. Comments from the public: Gary Grant, applicant for Pulte Homes, said he could wait until the next meeting to do a presentation. Ray Brandt from Brandt Engineering was present to answer any questions. Leo Fecht, 15475 Franklin Trail SE, questioned if they would be getting revised information in the mail. Kansier said they wouldn't send new notices but the neighbors did receive the revised plan with the notice. Suzanne Sharpe, 16483 Franklin Trail SE, said she and her neighbors were concerned with the additional traffic on Franklin Trail. Adding 148 townhomes brings an additional 300 cars to Franklin Trail. They would like to see some kind of diversion to traffic off Franklin Trail. People use Franklin Trail as a cutoff between Highway 13 and County Road 21. There is a lot of speeding. Karen Lantz, 5200 Credit River Road, said her concern is traffic. She felt the traffic has doubled in the two years she's been in the house and her property value has dropped because of it. By increasing traffic on a 50 mph road without stoplights will be madness. She felt they can't stop the developers but the Commission should address the traffic problems first. Linda Micko-Rasche, 16461 Franklin Trail, explained her problem getting out of her driveway with the existing traffic. She did not think it is a good idea to have another driveway on the proposed plat. Suggested slowing down the traffic on Franklin Trail might help. Would like to see the proposed driveway changed for safety reasons. Irene Mangan, 4810 BluffHeights Circle, attended the meeting on BluffHeights Apartments, and stated the neighbors were concerned with the traffic and additional children. Now another addition of homes is proposed with more traffic. Suzanne Sharpe, questioned the townhome price range. Gary Grant explained there would be two different owner-occupied housing units. The Village Homes (48 units) will be starting around $115,000 to $130,000 range. The Manor homes (100 units) will be in the $160,000 to $185,000 range. Kathy Blonigan, 5210 Credit River Road, said her biggest concern was traffic. She has been in contact with County Commissioner Barb Marschall regarding the traffic problems long before this proposal. It is very hazardous. Suggested reducing the speed L:\02FILES\02planning comrn\02pcminutes~V~N062402.doc 6 Planning Commission Meeting Jun* 24~ 2002 limit and adding turn lanes. The road issues need to be addressed first before adding all the proposexi townhomes, Starnsun pointed out the City was working on the ring road. Kansier said they would ask a representative from the Scott County Engineer's office to be at the next meeting to answer any questions.

NO JULY 8, 2002 INTRODUCTION: The Planning Department received a variance application from Dennis & Karen Perrier for the construction of a single-family dwelling and attached garage on nonconforming platted lots of record located at 16502 Inguadona Beach Circle. The applicant is requesting the following variances: 1. A 1.8-foot variance to permit a 25-foot structure setback to a front property line, rather than 26.8-feet as required by setback averaging [Ordinance Section 1102.405 Dimensional Standards (4)]. A 21.7-foot variance to permit a 3.23~foot rear yard setback, rather than the minimum required 25 feet [Ordinance Section 1102.405 Dimensional Standards (4)]. A 12.5-foot variance to permit a structure setback of 50-feet from the Ordinary High Water Elevation (OHWM), rather than the minimum setback of 62.5-feet as required by setback averaging [City Code Subsection 1104.308(2)]. 16200 Eagle Creek Ave. S.E., Prior Lake, Minnesota 55372-1714 / Ph. (952) 447-4230 / Fax (952) 447-4245 AN EQUAL OPPORTUNITY EMPLOYER 4. A 0.7-foot variance to permit a combined sum of side yards of 14.31-feet, rather than minimum of 15-feet as required for the sum of side yards on a nonconforming lot [Ordinance Section 1101.502 Required Yards/Open Space (8)]. 5. A 2-foot variance to permit a building wall 74-feet in length to be setback 7-feet to a side lot line rather than the minimum required 9-feet for building walls over 50-feet [Ordinance Section 1102.405 (6)]. DISCUSSION: Lots 17, 20, & 21, Inguadona Beach, were platted in 1924. The subject lots are legal nonconforming platted lots of record. The property is located within the R-1 District (Low Density Residential) and Shore~and District (SD). The subject lot has dimensions of 37.7' + 22.33~ (front) by 112.51' (east) by 60.31' (rear) by 107.59' (west), for a total lot area of 6,400 square feet, including the recently acquired 10'strip of the originally platted 20' easement adjoining the east side lot line. The applicant also owns Lot 20, and part of 21, with a combined lot area of 5,804 square feet. These lots are located across the private street from the proposed building site. According to Scott County records, the applicant does not own any other adjoining properties (Attachment 1 - Certificate of Survey). The applicant is proposing to demolish the existing structure and construct a new larger dwelling in its place. The proposed building footprint is approximately 75' deep by 40' wide for a total footprint of approximately 2,655 square feet, including a 904 sq. ft. attached garage. The main level floor plan includes a kitchen, ¼ bath, dining and family rooms, and main bedroom with a full bath. The lower level includes a full bath, two bedrooms, family room, and wet-bar area (Attachment 2 - Building Plans). The proposed structure includes a front setback of 25' which requires a 1.8' variance, because setback averaging requires a minimum 26.8' setback. The proposed west building wall is 74' long. City Ordinance requires that two inches per foot be added to the side yard setback for walls over 50' long (74' - 50' = 24' x 2" -- 48" or 4'). This requires a 2' variance to permit a 7' side yard setback as proposed rather than the minimum required 9'. The combined side yards total 14.3', and requires a 0.7' variance, as the minimum sum of side yards allowed is 15' on nonconforming lots. A proposed setback of 50' from the OHWM rather than a 62.5' setback as determined by averaging the existing structures east and west of the subject lot. The applicant submitted an impervious surface worksheet with a proposed 4,104 square feet of coverage area or 27% of the total area of the combined lots, including the common area between the rear lot line and shoreline of Prior Lake. L:\02 FILES\02va rian ce$~02-068\VarRpt.doc Page 2 The proposal is less than the maximum allowable area of 30% or 4,546 square feet. The applicant did not submit an existing impervious surface area for the current conditions on the subject property. Staff inspected Lots 20, and 21, and it appears a large portion of the area is covered in class 5 gravel that is considered impervious and would exceed the allowable 30%. The applicant is proposing to remove any gravel/class 5 area and will seed/sod this area to become non-impervious. The City Code requires all front and side yards to be sodded (Attachment 3 - Proposed Impervious surface Area). The submitted survey depicts an existing non-compliant water oriented accessory structure (boat house) located beyond the subject properties boundaries and on the common shoreline property that is jointly owned by the property owners of the Inguadona Beach subdivision. The structure is currently used by the property owners of Lot 16, and lot 17, for the storage of water oriented accessory equipment. The City Engineering Department has determined the survey must be revised to include 2' contours for drainage and grading purposes to be submitted with a building permit application for review. The Department of Natural Resoumes has responded to this variance request and the comments are attached (Attachment 4 - DNR Comments). Due to the depth of the lot, it appears some form °f front yard setback variance and some form of rear yard setback variance are necessary to allow a building pad. However, the proposed dwelling can be redesigned to meet the side setbacks and the setback from the Ordinary-High-Water-Mark (OHWM). Pulling the house back to meet the OHWM setback will also reduce the variance required to the rear yard setback. VARIANCE HARDSHIP STANDARDS 1. Where by reason of narrowness, shallowness, or shape of a lot, or where by reason of exceptional topographical or water conditions or other extraordinary and exceptional conditions of such lot, the strict application of the terms of this Ordinance would result in peculiar and practical difficulties or exceptional or undue hardship upon the owner of such lot in developing or using such lot in a manner customary and legally permissible within the Use District in which said lot is located. The subject property is a nonconforming lot of record and an existing condition over which the applicant has no control. Some form of front and rear yard setback variances will be 'required to build a reasonable single family dwelling for this site. However, the applicant can control the design L:~02FILES\02variances\02-068\VarRpt.doc Page 3 and size of the proposed structure and eliminate the need for all variances as requested, specifically #'s 2, 3, 4, & 5. 2. Cond'itions applying to the structure or land in question are peculiar to the property or immediately adjoining property, and do not apply, generally, to other land or structures in the Use District in which the land is located. Plats of this era (1924) crreated lots with smaller dimensions than are required today, and are peculiar to the lot and adjoining properties of the Inguadona Beach Subdivision. In addition, the substandard lot depth precludes the ability to build a dwelling without some form of front and rear yard setback variances. However, as requested, Variance #'s 2, 3, 4, & 5, do not meet the hardship criteria because a redesign can reduce or eliminate these variances. 3. The granting of the proposed Variance is necessary for the preservation and enjoyment of a substantial property right of the owner. Front and rear yard setback variances appear necessary for construction of a dwelling of reasonable size and preserve a substantial property right of the owner. However, as requested the setbacks to the OHWM, sum of side yards, eave encroachment, and building wall, may be reduced or eliminated with a revised building plan. 4. The granting of the proposed Variance will not impair an adequate supply of light and air to the adjacent property, unreasonably increase the congestion in the public streets, increase the danger of fire, or endanger the public safety. The granting of front and rear yard setback variances will not impair these stated values. The granting of the requested Variance #'s 2, 3, 4, & 5 appears to impair these stated values but does not appear to endanger the public safety or increase the danger of fire. 5. The granting of the Variance will not unreasonably impact on the character and development of the neighborhood, unreasonably diminish or impair established property values in the surrounding area, or in any other way impair the health safety, and comfort of the area. The granting of the front and rear yard setback variances for a future dwelling will not unreasonably impact the character of the neighborhood, or diminish property values or impair health, safety and comfort of the area. However, the granting of the requested Variance #'s 2, 3, 4, & 5 will unreasonably impact the character and development of the neighborhood. L:\02 FI LES\02variances\02-068\VarRpt. doc Page 4 6. The granting of the proposed Variance will not be contrary to the intent · of this Ordinance and the Comprehensive Plan. Since this is a substandard platted lot of record, the granting of the front yard setback as requested, and a reduced rear yard setback variance is not contrary to the intent of the Ordinances or the Comprehensive plan. Variance requests #'s 2 - 5, can be eliminated with a redesigned building plan and therefore they are contrary to the intent of these Ordinances and the Comprehensive Plan. 7. The granting of the Variance will not merely serve as a convenience to the applicant but is necessary to alleviate a demonstrable undue hardship or difficulty. A hardship exists with respect to the front and rear yard setback variances to alleviate a demonstrable undue hardship or difficulty to build a single-family dwelling. No hardship exists pertaining to variance request #'s 2 - 5, with design modifications. 8. The hardship results from the application of the provisions of this Ordinance to the affected property and does not result from actions of the owners of the property. A hardship results from the provisions of the Ordinance with regards to front and rear yard setbacks for the construction of a single family dwelling structure. However, the applicant can reduce the size of the proposed building to eliminate the remaining variance requests. 9. Increased development or construction costs or economic hardship alone shall not be grounds for granting a Variance. Financial considerations alone are not grounds for the granting of variances. In this case financial considerations are in addition to the other 8 hardship criteria for a front and rear yard setback variances. RECOMMENDATION: The staff believes that all of the variance criteria have been met with respect to the requested front yard setback variance #1, and some form of rear yard setback variance, such as,a rear yard setback of 15.73-feet in order to meet the minimum OHWM setback average of 62.5-feet. Due to the depth of the substandard platted lot of record and the required front and OHWM Setback averaging, a legal alternative building site does not appear to exist on the lot to allow for a single family dwelling of reasonable size for this use district. L:\02FILES\02vadanoes\02-068\VarRpt.doc Page 5 However, staff feels the proposed dwelling may be redesigned and reduced in size to reduce or eliminate variance requests 2, 3, 4, & 5. Therefore, the variance hardship criteria have not been met with respect to variance request #'s 2, 3, 4, & 5, as proposed by the applicant and staff recommends denial of these requested variances. Staff recommends the following conditions be included with approval of any variances deemed appropriate by the Planning Commission: 1. The resolution as adopted by the Planning Commission shall be recorded at Scott County within 60 days of adoption, and proof of recording along with the acknowledged City Assent Form shall be submitted to the Planning Department prior to the issuance of a building permit. 2. The applicant shall submit a revised certificate of survey to depict the approved variances and all conditions deemed appropriate by the Commission, along with the proposed finish grades with drainage and an erosion control plan. 3. The applicant shall submit an application for a Lot Combination of Lots 17, 20, & P.O. 21, and create one legally transferable document (Deed), and shall record said document at the Scott County Land Records Office. 4. The applicant/owner shall remove all existing impervious surface areas on the combined lots to create a total impervious surface area equal to or less than 30% of the total lots area. 5. The building permit is subject to all other applicable city, county, and state agency regulations. ALTERNATIVES: 1. Approve the variances requested by the applicant, or approve any variances the Planning Commission deems appropriate in the circumstances, in this case, the Planning Commission should direct staff to prepare a resolution with findings approving the variance requests. 2. Table or continue discussion of the item for specific purpose. 3. Deny the application because the Planning Commission finds a lack of demonstrated hardship under the zoning code criteria. ACTION REQUIRED: L:\02 FI LES\02variances\02-068~VarRpt.doc Page 6 The staff recommends alternative #1, approval of variance request # 1, and approval of some modified form of variance request # 2. Staff also recommends alternative # 3, denial of the requested variance #'s 2, 3, 4, & 5, for a lack of demonstrated hardship under the zoning code criteria. This requires the following two motions: 'i.

Because of conditions on the subject property and on the surrounding property, the proposed variance will result in the impairment of an adequate supply of light and air to adjacent properties, unreasonably increase congestion in the public streets, increase the danger of fire, and danger to the public safety, unreasonably diminish or impair health, safety, comfort, morals or in any other respect be contrary to the Zoning Ordinance and Comprehensive Plan. A legal building envelope exists on the subject lot that meets or reduces the requested variances for setbacks to the Ordinary High Water Mark, side yard, and sum of side yards. The applicant has control over the house design and shape, such that the hardship has been created by the applicant. Reasonable use of the property exists with a smaller building footprint. There is no justifiable hardship caused by the required setbacks and impervious surface coverage area as reasonable use of the property exists without the granting of the variance. The granting of the variance, as originally requested, is not necessary for the preservation and enjoyment of a substantial property right of the applicant. The variance will serve merely as a convenience to the applicant, and is not necessary to alleviate demonstrable hardship.

The proposed addition will be attached to the side of the existing building and extend to the rear lot line. The Main Avenue street side is determined to be the "Front Lot Line" as defined in Ordinance Section 1101.400. The following ,variance is requested: 1. A 10-foot variance to permit a O-foot structure setback from a rear property line rather than the minimum required 10-feet (Ord. Sec. 1102.1105: Dimensional Standards). DISCUSSION: The property was originally platted in 1934 as Cates Addition to Prior Lake. Another portion of the property was platted in 1977 as Langhorst 1st Addition. The property was again platted in the year 2000 as Lot 1, Block 1, Carlsons Hardware Addition. Mr. Carlson is the business owner, applicant, and property owner, along with Wallace & Delores Langhorst according to Scott County records. The lots dimensions are 135.31' (front) x 119.45' (front/side) x 76.98'+ 3'+ 56.47' (rear) x 112.26' (side) (Attachment 1 - Certificate of Survey). 1:\02files\02vadances\02-075\varrpt.doc Page 16200 Eagle Creek Ave. S.E,, Prior Lake, Minnesota 55372-1714 / Ph. (952) 447-4230 / Fax (952) 447-4245 AN EQUAL OPPORTUNITY EMPLOYER The subject building is attached to the building due east of the subject lot with a common exterior wall or 0' rear yard setback. The proposed addition is irregular in shape and is an extension of the existing west wall by 26' to within a couple feet of the side lot line, then turns 90 degrees east for 18.54' to within 9" of the side property line, and follows the side lot line for 56.9'+ 3' + 55.89' to the East lot line, then turns 90 degrees north for 19.8' along the rear lot line and terminates at the existing building wall. The addition includes a full basement to match the existing basement level. The delivery access is through an 8' overhead door on the east end of the addition with driveway access. (Attachment 2 - Building Addition Plans). The addition's exterior walls consists of 8" masonry walls to match the materials and design of the existing structure. The proposed building materials do not meet today's requirements for new structures, but are permitted for additions to existing buildings under the Section 1102.1407 (2) of the Zoning Ordinance. This request was referred to applicable City departments and utility companies for comment. The City Building Department noted, in part, that the applicant must provide soils and structural engineers' plans on the method of protecting the adjacent buildings. The City Engineering Department commented that the existing manhole is under the concrete of the loading dock, and a new manhole outside of building slab envelope must be built. In addition, the line from the new manhole to the existing becomes a private service. Integra Telecom noted that existing telephone lines that service building will need to be relocated. VARIANCE HARDSHIP STANDARDS 1. Where by reason of narrowness, shallowness, or shape of a lot, or where by reason of exceptional topographical or water conditions or other extraordinary and exceptional conditions of such lot, the strict application of the terms of this Ordinance would result in peculiar and practical difficulties or exceptional or undue hardship upon the owner of such lot in developing or using such lot in a manner customary and legally permissible within the Use District in which said lot is located. The existing lot can accommodate a revised and scaled down building addition without the setback variance. Conditions applying to the structure or land in question are peculiar to the property or immediately adjoining property, and do not apply, generally, to other land or structures in the Use District in which the land is located. The conditions that apply are not peculiar to the property or adjoining property, and do apply, generally, to other land or structures in the C-3 l:\02files\02varian ces\02-075\varrpt, doc Page 2 District. There appears to be a legal alternative for a redesigned addition that meets code requirements. 3. The granting of the proposed Variance is necessary for the preservation and enjoyment of a substantial property right of the owner. By redesigning the configuration of the addition, it can be built without the requested variance. 4. The granting of the proposed Variance will not impair an adequate supply of light and air to the adjacent property, unreasonably increase the congestion in the public streets, increase the danger of fire, or endanger the public safety. The granting of the variance appears to impair the supply of light and air to the adjacent property. The addition will not significantly impact the public streets or endanger public safety. 5. The granting of the Variance will not unreasonably impact on the character and development of the neighborhood, unreasonably diminish or impair established property values in the surrounding area, or in any other way impair the health safety, and comfort of the area. Staff is of the opinion that granting this variance will not impact the above stated values. 6. The granting of the proposed Variance will not be contrary to the intent of this Ordinance and the Comprehensive Plan. The granting of these variances is contrary to the intent of the Ordinance and Comprehensive Plan, which is to provide ordedy development and prevent over crowding of land and undue concentration of structures in relation to the land surrounding them. 7. The granting of the Variance will not merely serve as a convenience to the applicant but is necessary to alleviate a demonstrable undue hardship or difficulty. The proposed addition can be redesigned to eliminate the need for the requested variance. The granting of the variance is not necessary to alleviate a demonstrable hardship existing today, but for the proposed future addition. 8. The hardship results from the application of the provisions of this Ordinance to the affected property and does not result from actions of the owners of the property. 1:\02flies\02variances\02-075\varrpt.doc Page 3 The applicant is proposing the addition, and therefore the result is a required variance request. The variance would not be necessary with a redesign of the addition. 9. Increased development or construction costs or economic hardship alone shall not be grounds for granting a Variance. Redesigning the addition will eliminate the need for the requested variance. RECOMMENDATION: The Planning staff has determined that the variance request for the rear yard setback does not meet the nine hardship criteria, since it is a business decision to expand the existing building due to economic growth and the need for additional space for storage and display of materials. The applicant can redesign the addition to meet the required 10' setback with a comparable yet smaller addition. The staff therefore recommends denial of the requested variance. If the Planning Commission finds the variance request meets the hardship criteria, it should be subject to the condition that no outdoor storage of equipment or dum 2sters will be allowed without providing screening from public view. ALTERNATIVES: 1. Approve the variance requested by the applicant, or approve any variances the Planning Commission deems appropriate in the circumstances. In this case, the Planning Commission should direct staff to prepare a resolution with findings approving the variances requested. 2. Table or continue discussion of the item for specific purpose. 3. Deny the application because the Planning Commission finds a lack of demonstrated hardship under the zoning code criteria. ACTION REQUIRED: The staff recommends Alternative #3.

Carlson has applied for a variance from the Zoning Ordinance in order to permit the construction of an addition to a commercial building on property located in the C- 3 District (Specialty Business) at the following location, to wit; 16281 Main Avenue SE, legally described as Lot 1, Block 1, Carlsons Hardware Addition, Plat 25369, Scott County, Minnesota. 2. The Board of Adjustment has reviewed the application for variances as contained in Case #02-075PC and held hearings thereon on July 8, 2002. The Board of Adjustment has considered the effect of the proposed variance upon the health, safety, and welfare of the community, the existing and anticipated traffic conditions, light and air, danger of fire, risk to the public safety, the effect on property values in the surrounding area and the effect of the proposed variance on the Comprehensive Plan. Because of conditions on the subject property and on the surrounding property, the proposed variance will result in the impairment of an adequate supply of light and air to adjacent properties, unreasonably increase congestion in the public streets, increase the danger of fire, and danger to the public safety, unreasonably diminish or impair health, safety, comfort, morals or in any other respect be contrary to the Zoning Ordinance and Comprehensive Plan. An alternative legal building addition location that meets the required setback for the structure exists on the subject lot. The applicant has control over the plan design and shape, such that the hardship created has been created by the applicant. Reasonable use of the property exists without the building addition as proposed. 6. There is no justifiable hardship caused by the required rear yard setback, as reasonable use of the property exists without the granting of the variance. The granfmg of the variance, as originally requested, is not necessary for the preservation and enjoyment of a substantial property right of the applicant. The variance will serve merely as a convenience to the applicant, and is not necessary to alleviate demonstrable hardship. The factors above allow for an alternative structure to be permitted with a reduced variance or none at all. l:\02files\02variances\02-075~dnyres.doc l 16200 Ea§le Creek Ave. S.E., Prior Lake, Minnesota ,5,5372-1714 / Ph.

The boulder wall and fill were installed during the construction of a single-family dwelling that was approved under Building Permit # 01-1206. The applicant had submitted a building permit application and survey for the project, but the submitted materials did not include the retaining wall and the grading/filling work conducted within the bluff impact zone as part of the proposed project. Thus this work was done without a permit. An inspection of the project by staff discovered the work. (Attachment I - As Built Survey). The applicant requests the following variance: 1) A variance to permit the import of materials and grading/filling within the bluff impact zone (Ordinance Section 1104.402: Topographic Alterations/Grading And Filling). DISCUSSION: Lot 7, Block 12, Knob Hill, was platted in 1995. The subject property is located within the (R1) Low Density Residential, and (SD) (Shoreland Districts). The lot is riparian with a bluff impact zone. The platted dimensions of the lot are approximately 115' wide by 300' long for a total lot area of 34,678 square feet. The lot area above the 904-foot ordinary high water elevation is 27,151 square feet (Attachment 2 - Approved Survey). 16200 Eagle Creek Ave. S.E., Prior Lake, Minnesota 55372~1714 / Ph. (952) 447-4230 / Fax (952) 447-4245 AN EQUAL OPPORTUNITY EMPLOYER According to the attached survey, the top of bluff starts at the west lot line and follows the 930-foot elevation contour to approximately the center of the lot. The dashed line indicates the minimum 25' structure setback line from the top of bluff. The bluff impact zone is defined as "a bluff and land located within 20' from the top ora bluff'. The top of the bluff begins 5' inside of the setback line and continues lakeward through the bluff to the toe of the bluff or 904' contour. The applicant installed the boulders between the 908' and 910' contours and then backfilled behind the boulders to create the retaining wall. The length of boulder wall within the bluff impact zone is approximately 120' long. The wall appears to be less than 4' in height of unbalanced backfill. In addition the applicant placed a boulder retaining walt along the east lot line from the 929' elevation to below the 904' contour at the shoreline. A portion of the wall actually encroaches over the lot line and onto the adjoining property. The applicant must remove all portions of the wall that encroaches over the lot line, and the 5' drainage utility easement that runs inside of the lot line. In addition, no portion of the retaining walls may exceed 4' in height of unbalanced back fill or the wall is defined as a structure and must meet the required setbacks. Staff has posted a "Stop Work Order" on the project until all necessary corrections have been made. The applicant submitted a narrative titled Description Of Project for this variance request. In essence, the applicant claimed to be unaware of the ordinance violation when placing a row of landscape boulders and backfilling. Also, the applicant denied cutting into the base of the slope (Attachment 4 - Applicant Narrative). The applicant also submitted an engineer's letter by GEO Engineering Consultants dated June 14, 2002. The report addressed the impact the placement of the boulders and backfill will have on the site. The letter stated in part "In maintaining global slope stability, it is most important that soil is not excavated from the toe of the slope, as this will reduce the resistance against sliding of the soil mass. Conversely, by placing additional weight at the toe, such as boulders and additional soil, will increase sliding resistance of the soil mass'". The report also included recommendations regarding slope stability and surface erosion by not disturbing existing surface vegetation and trees so the site development will not interfere with adequate drainage for the site or adjacent properties (Attachment 3 - Engineers Site Observation Letter). Prior to issuance of a certificate of occupancy for this project, the owner must provide certification from a professional engineer that the final grading of the site was completed in compliance with an approved grading plan, and that all conditions of the engineers report have been adhered to. L:\02FILES\02variances\02~076\VarRpt. doc Page 2 The City Engineering Department reviewed this variance request and has no comment. The Area Hydrologist with the Department of Natural Resources submitted comments on this request. The DNR visually inspected the site and directed the applicant to correct the dprap boulders placed along the shoreline. He reserved judgment on the work in the bluff impact zone until an engineers report was submitted, but commented that removing the boulders and imported fill at this point may have greater potential for erosion and slope failure. VARIANCE HARDSHIP STANDARDS Where by reason of narrowness, shallowness, or shape of a lot, or where by reason of exceptional topographical or water conditions or other extraordinary and exceptional conditions of such lot, the strict application of the terms of this Ordinance would result in peculiar and practical difficulties or exceptional or undue hardship upon the owner of such lot in developing or using such lot in a manner customary and legally permissible within the Use District in which said lot is located. There is no question regarding the exceptional topography for this lot and the existence of a bluff impact zone. However, the applicant created the situation by constructing the boulder wall and backfilling in violation of the Shoreland Ordinance. Therefore, staff feels the vadance as requested does not meet this hardship standard due to the applicants unapproved land alterations. e Conditions applying to the structure or land in question are peculiar to the property or immediately adjoining property, and do not apply, generally, to other land or structures in the Use District in which the land is located. The bluff topography is a unique condition of the property and the immediate adjoining property, and does not apply, generally, to other land in the Shoreland District. The granting of the proposed Variance is necessary for the preservation and enjoyment of a substantial property right of the owner. The granting of the variance is not necessary for the preservation and enjoyment of a substantial property right of the owner because the owner created his hardship by changing the existing conditions of the bluff impact zone with the boulder wall and back filling. L:\02FILES\02vadances\02-076\VarRpt.doc Page 3 4. The granting of the proposed Variance will not impair an adequate supply of light and air to the adjacent property, unreasonably increase the congestion in the public streets, increase the danger of fire, or endanger the public safety. The granting of the variance for the importing of materials in the bluff impact zone should not impair adequate light and air to adjacent properties, nor increase the danger of fire, or endanger the public safety provided a bluff failure does not occur. 5. The granting of the Variance will not unreasonably impact on the character and development of the neighborhood, unreasonably diminish or impair established property values in the surrounding area, or in any other way impair the health safety, and comfort of the area. The granting of the variance does not appear to unreasonably impact on the character and development of the neighborhood. However, should a bluff failure occur, this may impair the health safety of the area. 6. The granting of the proposed Variance will not be contrary to the intent of this Ordinance and the Comprehensive Plan. The granting of the variance request for importing material in the bluff impact zone is contrary to the intent of the City Ordinance, which is to prohibit the importation of materials in the bluff impact zone. 7. The granting of the Variance will not merely serve as a convenience to the applicant but is necessary to alleviate a demonstrable undue hardship or difficulty. The requested variance appears to serve as a convenience to the applicant because the applicant created the need for the variance by importing materials into the bluff impact zone without authorization. 8. The hardship results from the application of the provisions of this Ordinance to the affected property and does not result from actions of the owners of the property. The requested bluff variance is a result of the property owner's actions, and could be eliminated by correcting the violation and removing the imported materials and restoring the area to its original condition. 9. Increased development or construction costs or economic hardship alone shall not be grounds for granting a Variance. L:\O2FILES\O2variances\O2-O76\VarRpt,doc Page 4 Financial considerations alone are not grounds for the granting of a variance request, but appear to be a consideration in this case due to the expense of removing the boulders and fill. RECOMMENDATION: Staff believes that all nine-hardship criteria have not been met with respect to the requested variance to permit the import of materials and grading/filling in a bluff impact zone. The applicant created the hardship when the boulder retaining wall and fill were installed on the subject property. The site was not developed as approved under Building Permit # 01-1206. The staff therefore recommends denial of the requested variance as proposed by the applicant. ALTERNATIVES: 1. Approve the variances requested by the applicant, or approve any variances the Planning Commission deems appropriate in the circumstances. In this case, the Planning Commission should direct staff to prepare a resolution with findings approving the variance requests. 2. Table or continue discussion of the item for specific purpose. 3. Deny the application because the Planning Commission finds a lack of demonstrated hardship under the zoning code criteria. ACTION REQUIRED: Staff recommends Alternative #3. A Motion and second adopting Resolution 02-010PC denying the variance to permit the importation of material into a bluff impact zone as requested by.the applicant. L:\02 FILES\02variances\02-076\VarRpt.doc Page 5 RESOLUTION 02-010PC A RESOLUTION DENYING A VARIANCE TO PER3$IT THE IMPORTATION OF MATERIALS WITHIN A BLUFF IMPACT ZONE BE IT RESOLVED BY the Board of Adjustment of the City of Prior Lake, Mi~mesota; FINDINGS Hillcrest Homes, Inc. have applied for a variance from the Zoning Ordinance in order to permit the construction of a boulder retaining wall and filling within the bluff impact zone to remain on the property located in the Low Density Residential (R1) and Shoreland Districts (SD) at the following location, to wit; 14764 Rosewood Road NE, Prior Lake, MN, legally described as follows: Lot 7, Block 2, Knob Hill, Scott County, Minnesota. 2. The Board of Adjustment has reviewed the application for variances as contained in Case #02-076PC and held hearings thereon on July 8, 2002. The Board of Adjustment has considered the effect of the proposed variance upon the health, safety, and welfare of the community, the existing and anticipated traffic conditions, light and air, danger of fire, risk to the public safety, the effect on property values in the surrounding area and the effect of the proposed variance on the Comprehensive Plan. Because of conditions on the subject property, a legal alternative does exist by removing the imported materials placed within the bluff impact zone, the proposed variance will result in the impairment of an adequate supply of light and air to adjacent properties, unreasonably increase congestion in the public streets, increase the danger of fire, and danger to the public safety, unreasonably diminish or impair health, safety, comfort, morals or in any other respect be contrary to the Zoning Ordinance and Comprehensive Plan. The proposed variance request is a result of the property owners actions by importing materials and grading/filling within a bluff impact zone. The applicant has control over the grading and filling work completed, as such, the hardship has been created by the applicant. l:\02files\02variances\02-076\dnyrs.doc 1 16200 Ea§le Creek Ave. S.E.. Prior Lake, Minnesota 55372-1714 / Pr. (952) 447 4230 / Fax (952) 447-4245 AN EQUAL OPPORTUNITY EMPLOYER While there is an existing structure on the lot, there is not justifiable hardship caused, and that reasonable use of the property does exist without the granting of the variance. There is a legal alternative solution for a revised grading and filling plan, and to correct the existing ordinance violation without the requested variance. The granting of the variance, as determined by the Planning Commission, is not necessary for the preservation and enjoyment of a substantial property right of the applicant. The variance will serve merely as a convenience to the applicant, and is not necessary to alleviate demonstrable hardship. 8. The contents of Planning Case #02-076PC are hereby entered into and made a part of the public record and the record of decision for this case. CONCLUSION Based upon the Findings set forth above, the Board of Adjustment hereby denys the following variance to allow the importation of materials within a bluff impact zone as shown in Attachment 1 - Certificate of Survey): I. A Variance to permit the importation of materials and grading/filling within a bluff impact zone. Adopted by the Board of Adjustment on July 8, 2002. ATTEST: Anthony J.

You authorized our service on March 4, 2002. The scope of service consisted of observing and documenling the eondRions after recent landseaping al the site. On March 4, 2002, we observed the condition of c. xistlng slope at the rear of the property, between the house under constmc~iun and the lake. Il appears thc steepest portion of the slope has been reimively undisturbed. At the taller portion of the slope, the natural access and drainage to the lake was improved. We understand this access was improved primarily by placing landscape boulders and some additional fill on the lakeside of the accel. This was placed to level the access and provide surface drainage to the lake and away from adjacent properly. In addition, boulders were placed on the inside (house side) of the access at the toe (boltom) oftbe slope. At this lime, the boulder wails are on the order of 2 to 5 feel high, with final grading yet lo he completed, In maintaining global slope stability, it is most important that soil is not excavated from the toe of the slope, as this will reduce the resistance against sliding of the soil mass. Convci'sely, by placing additional weight at the toe, such as boulders and additional soil, will increase sliding resistsnee of the soil mass. It did not appear that soil had been removed bom the toe of the slope, based on our observations. The new fill and boulders placed at the toe should aid in global stability. Another aspec~ of slope stability is surface crosion. Thc existing surface vegetation and trees should not be disturbed to minimize the potential for surface erosion. The surface of the steep slope appeared lo be undisturbed, based on our visual observations. We recommend the existing trees and surface vegetation remain undisturbed to minimize the erosion potential, m Z m m 0 m Z Project Number: 001-0071-$372.2A Psge 2 With ~ants to the improved lake aw. ess, we recommend the surface be seeded ~vith gra~s, or a sut'faoe layer of compacted ~ravel ot other sur~ be pla~ed lo minimize the potential for erosion. In our opinion~ th~ recent landecaping should not influence the em~bili~ of the existing slope. This judgcn~n is based on our ob.~rvation of existing comtitions, thc previous subsurface exploration results, and our expcricncc. It should be noted, to properly analyze slope stability requires subsurface exploration at th~ top, midway, and at ibc toe of the slope. In lgidition, sophisticated triaxial tcsting of rcpresenlatlve undisturbed samples should be performed. This data should then be analyzed using applicable computer nnnllais t~chniques.

Oeotechnieal Engineer ~eo Engineering Consultants Inc HILLCKEST DESCRIPTION OF PROJECT "A Builder Driven By Quality Craftsmanship and Vctlue." During placement of rip-rap along the shoreline of this property, we also placed a row of landscape boulders along the base of the slope. The placement of these boulders was two fold. First, was to provide a landscape definition between the landscaped area near the lake and the natural area on the hill. Second, was to provide an area for any washed sediment from the slope to accumulate without washing into the landscaped grass area near the lake. The placement of these boulders was not intently done to violate the ordinance. I honestly did not think what we were doing was going to cause a problem. However, upon investigation of this placement it is determined that part of the area where we placed the landscape boulders is in a bluff impact zone. Current ordinance does not allow for any grading or importation of fill in the bluffimpact zone. We have graded and imported fill in this area when we placed and backfilled behind the rocks placed at the toe of the slope. A few items of importance. When installing the landscape boulders at the toe of the slope we did not cut into the base at any point in time. Nor did we create a flat yard area near the lake with the placement of the boulders. We merely placed them at the toe of the slope and backfilled behind. All previous survey show the fiat area existed prior to any work we have done. At this point in time we would like to leave what work has been completed. We do not believe we have impacted the slope in any way, and in fact believe we helped the situation in regards to the drainage and slope stability. We had an engineering report completed, and it is attached. Builder License #20036544 · Member of the Builders Association of the Twin Cities P.O.

The Planning Commission initiated this amendment on June 10, 2002. DISCUSSION: The Zoning Ordinance currently defines water-oriented accessory structures as follows: A building of 120 square feet or less used to store boating accessories and equipment located on lakeshore lots that contain steep slopes equal to or greater than 20% which because of the relationship of its use to a surface water feature reasonably needs to be located closer to the lakeshore ordinary high water mark (OHW) than the normal structural setback requirement. Section 1104.308 (4) regulates the use and location of these structures. This sections currently reads as follows: (4) Water-Oriented Accessory Structures: One water-oriented accessory structure may be allowed per lot on General Development (GD) lakes that have Municipal sewer and water, provided a building permit is obtained from the City and the following criteria are met: a. The lot contains a slope equal to or greater than 20% measured from the front of the principal structure to the ordinary high water mark; and 1:\02flles\O2ordamend~zoning\O2-O72\pc report.doc 16200 Eagle Creek Ave. S.E., Prior Lake. Minnesota 55372-1714 / Ph. (952) 447-4230 / Fax (952) 447-4245 AN EQUAL OPPORTUNITY EMPLOYER b. The structure shall not occupy an area greater than 120 square feet, and the maximum height of the structure must not exceed 10 feet, including the roof; and c. The structure shall be located in the most visually inconspicuous portion of the lot as viewed from the surface of the lake, assuming summer, leaf- on conditions. The minimum setback requirement must be at least 10 feet from the ordinary high water mark and must meet the other applicable side yard setbacks. The slope shaft be verified by a certificate of survey prepared by a registered surveyor; and d. The structure shaft not be designed or used for human habitation and shaft not contain water supply or sewage treatment facilities. However, the structure may contain electrical and mechanical systems; and e. The structure shaft be constructed of treated wood and/or block that is compatible with the principal structure and designed to reduce visibility as viewed from public waters and adjacent shorelands by vegetation, topography, increased setbacks or color, assuming summer, leaf-on conditions; and f. If the proposed structure will be located below the regulatory flood plain elevation, the structure shaft be built compliant with applicable flood- proofing requirements of the Building Code and Section 1105 of this Ordinance; and g. Trees that are 4 inches in caliper or larger should not be removed for the erection of a water-oriented accessory structure. If removal is necessary, replacement with like trees shall be made with the approval of the Zoning Administrator. Erosion control measures shall be implemented and aft disturbed vegetation replaced with sod or suitable landscaping materials; and h. The structure shaft be attached to a permanent foundation so as to be immovable from its approved location. Both the definition and the regulations for these structures are more restrictive than the existing language in the Minnesota State Shoreland Rules. The additional restrictions are intended to limit the number and size of accessory structures on the lot, while at the same time allowing property owners with access and storage of recreational equipment on riparian lots with steep slopes. On June 10, 2002, the Planning Commission initiated an amendment to the Zoning Ordinance as follows: · An amendment to the definition of a water-oriented accessory structure to include gazebos, screen houses and detached decks. · An amendment to Section 1104.308 (4) that would reduce the setback for water-oriented accessory structures to 50' on lots without steep slopes. The 1:\02files\02ordamend~.oning\02-072\pc report.doc Page 2 setback for these structures on lots with slopes greater than 20% would still be 10 feet from the Ordinary High Water Elevation. The attached draft ordinance includes the specific language for this amendment. The proposed amendment is still more restrictive than the Minnesota Shoreland rules, which include a much broader definition for water-oriented accessory structures, and fewer limitations on setbacks. The Lake Advisory Committee considered this amendment at its meeting on June 18, 2002. The LAC recommended approval of the amendment. RECOMMENDATION: Section 1108.600 of the Zoning Ordinance states specific findings that must be met to change the ordinance. These are: 1. There is a public need for the amendment. 2. The amendment will accomplish one or more of the purposes of this Ordinance, the Comprehensive Plan, or other adopted plans or policies of the City. 3. The adoption of the amendment is consistent with State and/or Federal requirements. Whether or not a water-oriented accessory structure should be allowed on all riparian lots is a policy issue. The current ordinance provisions were generally intended for aesthetic purposes. Earlier platted riparian lots tend to have smaller dimensions and less total area than is required for lots today. There has also been concern about the encroachment of structures on the lake. The staff has no objections to the proposed amendment. The proposed amendment will allow additional storage on riparian lots, and will still limit the encroachment of structures on the shoreline. ALTERNATIVES: 1. Recommend the Council approve the amendments as proposed, or with changes specified by the Planning Commission. 2. Recommend the Council deny the proposed amendment. 3. Table or continue discussion of the item for specific purpose. 1:\02files\02ordamend~zoning\02-072\pc report.doc Page 3 RECOMMENDATION: The staff recommends Alternative #1. ACTION REQUIRED: A motion and second recommending approval of the proposed amendment as recommended by staff and indicated in the attached draft ordinance. REPORT ATTACHMENTS: 1.

The property owner, Prior Lake Apartments, has also signed the application. The application includes the following requests: · Approve a Planned Unit Development Preliminary Plan; · Approve a Preliminary Plat. This property is zoned R-4 (High Density Residential). The proposal calls for a townhouse development consisting of a total of 148 dwelling units on 28.19 acres. The development also includes parkland and private open space. On May 21, 2002, the applicant submitted a complete application that called for a development consisting of 170 units. Since the application was complete, the staff scheduled a public hearing before the Planning Commission. Notice of this heating was published in the Prior Lake American and sent to owners of property within 500' of the site. This original proposal involved filhng a large portion of the wetland on the site. The Wetland Technical Evaluation Panel (TEP) subsequently advised the developer that the proposal was inconsistent with the Wetland Conservation Act, and could not be approved. 16200 l:\02files\02subdivisions\02prelim plats\timber crest\timber pc2.doc Page 1 Ea§le Creek Ave. S.E., Prior Lake, Minnesota 55372-1714 / Ph. (952) 447-4230 / Fax {952) 447-4245 AN EQUAL OPPORTUNITY EMPLOYER As a result of the TEP decision, the developer submitted new plans on June 1 I, 2002. Because of the timing of this submittal, the staff has not had the opportunity to review these new plans. In addition, the developer must submit a revised wetland mitigation plan and revised storm water drainage calculations. However, since the public hearing had already been published and notices sent, the staff had no choice but to place this item on the agenda. The Planning Commission opened the public hearing on June 24, 2002, and accepted limited testimony. The Plarming Commission then continued the public hearing to July 8, 2002, to allow staff time to further review the revised plans. PHYSICAL SITE CHARACTERISTICS: Total Site .Area: The total site consists of 28.19 acres. The net area of this site, less County road right-of-way and wetlands, is 21.87 acres. Tol~oeral~hy: This site is fairly hilly, with elevations ranging from 976' MSL at its highest point at the southeast comer of the site to 922' MSL at the lowest point in the wetland on the northwest side of the site. The entire site generally drains towards the wetland located along the northwest side of the site. Vegetation: This site includes a large number of trees and wetland area. The size and species of the majority of the trees on the site, such as box elder and elm trees, are not considered significant under the City tree preservation ordinance. The applicant has submitted an inventory of the significant trees on the site, which identifies 791 caliper inches of significant trees. The Tree Preservation Ordinance allows removal of 25% of the total caliper inches for grading and utilities, and removal of an additional 25% of the total caliper inches for building pads without tree replacement. Removal of additional caliper inches requires replacement at a rate of 1/2 caliper inch for each caliper inch removed. Initial calculations indicate no tree replacement is required. Wetlands: There is one wetland located within this site, with a total area of 5.05 acres. The proposal impacts 0.41 acres of this wetland for the creation of a storm water pond and grading for building pads. The disturbed wetland will be mitigated on the site. Access: Access to the site is from Bluff Heights Trail on the southeast side and Franklin Trail on the southwest side of the property. Although the property is adjacent to TH 13 and CSAH 21, there will be no access to either of these roads. 2020 Comprehensive Plan Designation: This property is designated for High Density Residential uses on the 2020 Comprehensive Plan Land Use Map. The entire site is located within the current MUSA boundary. l:\02files\02subdivisions\02prelim plats\timber crest\timber pc2.doc Page 2 Zoning: The site is zoned R-4 (High Density Residential). The applicant is not requesting a rezoning as part of this application. The R-4 district permits a maximum density of 30 units per acre. PROPOSED PLAN Densi .ty: The plan proposes 170 townhouse units on a total of 28.19 acres. based on the buildable acres of the site, or in this case on 21.87 net acres. density proposed in this plan is 6.77 units per acre. Density is The overall Lots: The preliminary plat consists of 148 lots for the townhouse traits. There are also three lots for the common open space. The proposal also includes three outlots. Outlot A is the private street system. Outlot B, located at the southwest comer of the site is intended as parkland. Outlot C is the wetland area. Building Styles: There are two different townhouse.building styles proposed. The first style, called Village Homes, is a 2-story, attached single family style dwelling with tuck- under garage. These buildings are located on the south side of the site. The plan includes 48 of these units in 6- and 8-unit buildings. Each of the units in these buildings includes a 1-car garage and approximately 977 square feet of living space on the upper two floors. The buildings are 35' high at the front, with vinyl siding exteriors and brick face and vinyl shakes for accents. The second building style, called Manor Homes, is a 2-story attached single family dwelling. There are 100 units in 25, 4-unit buildings. These buildings consist of a lower level, 2-car garage, rear yard decks and 1,595 square feet of living space. These buildings are 29' high, with vinyl siding exteriors and brick face and vinyl shakes for accents. Building elevations and sample floor plans for each of these buildings are attached to this r~port. The Zoning Ordinance requires 60% of the exterior build'mg materials for townhouse buildings with more than 4-units consist of Class I materials, such as brick or cement stucco. The developer is requesting a modification to this requirement as part of the PUD plan for the 6- and 8-unit buildings. Setbacks: The plan proposes a 25' setback from the from property line, a minimum 30' rear yard setback, and a minimum 25' building separation (foundation to foundation) between the townhouses. The plan also notes a 30' setback from any wetland. The Zoning Ordinance requires a min'maum setback between buildings equal to ½ the sum of the height of the buildings. In this case, the minimum distance between buildings would be 35' for the Village Homes and 29' for the Manor Homes. The developer is requesting a modification to this requirement as part of the PUD. l:\02files\02subdivisions\02prelim plats\timber crest\timber pc2.doc Page 3 Lot Coverage: The R-4 district allows a maximum ground floor area of 0.35. The ground floor area proposed in this plan is 0.125. Traffic Impact Report: The developer has submitted a traffic study for this development. This study indicates the proposed development will generate a total of 868 trips. The TIR also indicates that the Level of Service (LOS) at the intersection of TH 13 and CSAH 21, and at CSAH 2i and Franklin Trail, would not fall below the existing LOS as a result of the trips generated by this development. The report also compares the number of trips generated by this development to the number of potential trips generated by the number of units permitted by the R~4 zoning. A copy of the submitted TIR is attached to this report. Streets: This plan proposes a private streets system for this development. There are two private streets designed to serve the townhouse development. The first is an extension of Bluff Heights Trail, 1,450' to the east where it intersects with Franklin Trail. This intersection is located 260' from the intersection of CSAH 21 and Franklin Trail. While not ideal, it is the only possible location for the intersection. The second private street is called Timber Crest Drive, and it extends 1,000' from the west leg of Bluff Heights Trail to the east leg of Bluff Heights Trail. Both of the private streets are designed with a 32' wide surface, and adjacent easements. The private streets meet the requirements of Section 1004.415 of the Subdivision Ordinance. The developer is also requesting a modification as part of the PUD plan to allow private streets. Sidewalks/Trails: The plan proposes a sidewalk on the north side of Bluff Heights Trail. Sanitary Sewer: Sanitary sewer will be extended from the existing sewer main which is located on this site. A portion of the existing sewer line must be relocated and the easement across the property vacated. Water Main: Water mains will be extended from the existing lines in Bluff Heights Trail and in Franklin Trail. Storm Sewer: The plan proposes a series of catch basins and storm sewer pipe to handle the storm water runoff on this site. The system will direct runoff to the north to a NURP pond on the north side of this site. The Engineering Department has noted the entire site drains to catch basins located at a low point on Bluff Heights Trail, in front of units 38 and 39. The Engineering Department feels storm drainage is concentrated in too few places on this site and the system should be redesigned so it is disseminated to more catch basins. The Engineering Department also noted that revised storm sewer and hydrology were submitted on June 26, 2002. Further review of this submittal is required. Parks: This plan includes a 2.72 acre park site, located at the southwest comer of the site. This is the best location for a park on the site, in that it is accessible to both this ]:\02files\02subdivisions\02prelira pla[q\timber crest\timber pc2.doc Page 4 development and other developments in the area. The site must be graded to meet minimum standards. Useable Open Space: The R-4 district also requires 600 square feet of useable 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 88,800 square feet; the plan indicates a total of 115,909 square feet. The staff has some concerns about the useable open space on this site. The Zoning Ordinance defines Useable Open Space as "a required ground area or terrace on a lot which is graded, developed, landscaped and equipped and intended and maintained for either active or passive recreation or both, available and accessible to and usable by all person occupying a dwelling unit or a rooming unit on the lot and their guests. Usable open space has a minimum dimension of 3O feet. Roofs, driveways and parking areas do not constitute usable open space." The largest area of open space, located in the center of Block 3, will have slopes of 16-29% after the site is graded. The question is whether or not this area can really be considered usable. Parking: The proposal provides at least 2 spaces per dwelling unit, which is consistent with the minimum Zoning Ordinance requirements. Each the 100 Manor Home units have two car garages; each of the Village Home units have a one-car garage. The plan also provides 62 off-street parking spaces in the townhouse area for guest parking. A total of 310 off-street parking spaces are provided. The proposed private streets will not provide any on-street parking. Landscaping: Section 1107.1900 lists the landscaping requirements for this development. Perimeter landscaping is required at a rate of 1 tree per unit or 1 tree per 40' feet of perimeter, whichever is greater. Our calculations indicate a total of 148 trees are required for this site. The developer has submitted a landscaping plan that identifies 315 trees, which exceeds the proper number of trees for the development. This plan is also consistent with ordinance requirements for size and species of the plantings. The plan does not indicate whether an irrigation system will be provided. The plan also has some discrepancies between the key and the actual trees shown on the site. These discrepancies should be corrected. Tree Replacement: The applicant has submitted an inventory identifying 791 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. In this case, the proposal removes 29.4% for road and utility purposes and 14.5% for building pads and driveways. Tree replacement is required at a rate of ½ caliper inch per 1 caliper inch removed. In this case, replacement of 17.125 caliper inches, or 7, 2 V2 inch trees, is required. The landscaping plan includes more than adequate numbers oftreas to meet this requirement. l:\02files\02subdivisions\02prelim plats\timber crest\timber pc2.doc Page 5 Signs: There are no signs identified for this project. Lighting: The developer has not indicated whether or not street lights will be provided on the private streets. Phasing: No phasing plan has been submitted for this project. ANALYSIS: PUD Prelimhtarv 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 is utilizing standard construction and design practices for the townhomes. The lookout style of the buildings in some areas utilizes the natural grades of the site where possible. A similar development, without the private streets and setback modifications, is possible as a conventional development in the R-4 district. (2) Higher standards of site and building design. Same as above. (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 common open space on the site will be available to all residents of the development as passive open space. However, it is questionable as to how much of this area is useable based on the grades of the site. The same amount of common open space is required as part of a conventional development. (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. 1:\02files\02subdivisions\02prelim plats\timber crest\timber pc2.doc Page 6 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 use of the private streets allows for fewer driveway openings on the public streets. (7.) Preserves and enhances desirable site characteristics including flora and fauna, scenic views, screening and buffering, and access. The town_house units are sited to take advantage of the natural views of the wetlands. The plan provides screening from the adjacent County road. (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 use(s) 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 park dedication or open space dedication over and above that required under conventional procedures. Section 1106.300 states the quality of building and site design proposed by the PUD will enhance the aesthetics of the s~ite 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. The design creates a unified environment in that all of the buildings will be constructed of similar materials. The extension of the existing private street allows for efficient movement of traffic. The landscaping plan will also enhance this area. l:\02flles\O2subdivision$\O2prelim plats\timber crest~timber p¢2.doc Page 7 (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. (3) Ifa 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 constructed in a single 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 200feet o f frontage on a public right-of-way. 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-1" or "R-2" Use District. c. No building within the project shall be nearer to another building than ~ 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 32' wide surface. The developer is requesting a 32' wide private street. The additional 18' of right-of-way would be accommodated by the use of easements adjacent to the private road. · Reduced setbacks between buildings. The required separation between buildings under the PUD provisions is ½ the sum of the heights of the buildings, or 29' and 35' in this case. The developer is requesting a 25' separation between the buildings. · Exterior building materials. The Zoning Ordinance normally requires Class I building materials on buildings with more than 4 units. Class I materials 1:\02files\02subdivisions\02prelim plats\timber cresfltimber pc2.doc Page 8 primarily consist of brick, marble, granite, textured cement stucco and glass. On buildings with 4 or fewer dwelling units, vinyl siding is a Class I material. These modifications are permitted under the PUD provisions at the discretion of the Council. Prelimina~. Plat: The primary issue relating the preliminary plat is the design of the storm water system. The Engineering Department has concerns about the workability of the proposed design. The Engineering Department has recommended the system be redesigned to disperse the catch basins throughout the site, and to eliminate the rear yard drainage. Staff Recommendation: One of the major issues pertaining to this development is whether or not the plan meets the PUD criteria. The primary justification for a PUD appears to be the use of the private streets. A cluster development of this type is permitted in the R-4 district, so a similar development with public streets, and meeting the required setbacks could be done without a PUD. The plan is consistent with the requirements for a conventional cluster development. The other major issue pertaining to this development is the design of the storm water runoff system. There are several issues pertaining to the proposed design that must be addressed. It is more than likely that the system will need to be redesigned entirely. This site is zoned R-4, and is appropriate for a higher density residential development. Some consideration should be given to the use of this site for multi-family buildings. It may be possible to develop a similar or greater number of units on the site in fewer buildings. Fewer buildings would also potentially disturb less of the site. If the Planning Commission finds that the PUD process is appropriate for this development, the staffwould recommend the following conditions be attached: 1. The developer must address all of the issues in the memorandum from the Cio~ Engineer dated July 3. 2002. PLANNING COMMISSION RECOMMENDATION: At this time, the Planning Commission should make a recommendation on the proposed PUD Preliminary Plan and Preliminary Plat. ALTERNATIVES: 1. Recommend approval of the PUD Preliminary Plan and the Preliminary Plat subject to the above conditions. 2. Table this item to a date specific, and provide the developer with direction on the issues that have been discussed. 1:\02files\02subdivisions\02prelim plats\timber crest\timber pc2.doc Page 9 3. Recommend denial of the request. 4. Other specific action as directed by the Planning Commission RECOMMENDATION: The Planning staff recommends Alternative #3. There are several major issues on this site that must still be resolved. ACTION REQUIRED: A motion and second recommending denial of the following requests: · Approval of a Planned Unit Development Preliminary Plan to be known as Jeffers South subject to the above conditions; · Approval of a Preliminary Plat to be known as Jeffers South, subject to the above conditions.

The property is zoned for High Density Multiple and the proposal is for the construction of 148 townhome units to be sold which is allowed in the zoning..The minimum property size for a PUD is 10 acres. This site contains 28.19 acres although 1.27 acres was taken a number.of years ago by the County for County Road No. 21 and Franklin Trail although title was not takem The PUD ordinance requires the site to front on at least 200 feet ora public street and this site fronts on more than 1900 feet of public street on the County Road No. 21 side alone plus the State Trunk Highway No. 13 side has an additional 1000 feet of frontage. There is a significant wetland (5.05 acres) located on the property that will be somewhat altered and a mitigation plan is included in the proposal. The property title is abstract and none is torrens. There are 72 trees that fall within the City standards for significant trees of which 40 will not be removed. The tree replacement plan more than replaces the amount of trees removed. A variance from the Zoning Ordinance is being requested for 25 foot setbacks between the 4-unit buildings and for 30 foot setbacks between the buildings with 6 and 8 units. The Zoning calls for 30 foot and 35 foot setbacks respectively A variance from the Zoning Ordinance regarding the exterior finish is also being requested from the 60% Class I material requirement for the buildings that have more than 4 units. It is requested that the exterior finish as presented in the plans be allowed. These variances will help to make this a housing-affordable project. The land use currently is just vacant land. The zoning is for multiple family and this proposal is for multiple family albeit lower density than the maximum allowed under the ordinance. The adjacent property to tbe.South consists of apartments, condominiums and several three-unit and four-unit residential buildings. A vacant piece of property is adjacent and southerly ofth6 southwestern portion of this development. A proposal is before the City for the construction of a 49-unit apartment building to be known as Bluff Heights Apartments. The zoning is the same as this project. I believe that the PUD allows for this project to be a much more desireable development than an apartment project. The topography slopes from the south to the northwesterly and the wetland. Much more site grading would be needed to construct apartments. The flow of the topography will be maintained to drain in the same general direction. The Village Homes along the southerly side of the property substantially reduce the grading required as they are tuck-under style and provide an approximate 8 foot drop along the southerly area of the project. Access to the project from County Road No 21 was part of the process when the land was taken from the current fee owners some years ago. It has been requested by the County Highway Department to eliminate this access and we have agreed to do so. The current owners are very much against this but that will become a'gr~ot poinf'ifthe project becomes a reality. There is a substantial area of 9.23 acres in OUTLOT C that will become an area for casual walking around the wetland. This will be an amenity for the residents for bird watching and other nature activities. Most of the trees along the westerly side of the wetland will be removed to make way for wetland mitigation activities. None of these trees falls into the category of the trees that the City Ordinance determines to be significant. This will enhance the view for townhome owners and for the public walking or driving by. The streets serving the townhomes are private and a sidewalk is planned along the northerly side of BluffHeights Trail. Sanitary sewer and city water will be included with the construction. A sanitary sewer currently crosses the property of which part will be relocated to better serve the proposed layout. Natural gas, electricity, telephone and cable will be part of the development of the project. The ordinance requires 296 parking spaces and the proposal provides 310 spaces. No parking along the street has been used in calculating the 310 spaces. Park dedication in the amount of 10% of the property requires that 2.69 acres be set aside. OUTLOT B contains 2.72 acres and will be deeded to the City. The existing zoning is R-4 (High Density Mukiple) and the proposed zoning is Planned Unit Development R-4 (High Density Multiple). The Comprehensive Land Use Plan indicates Urban High Density. The allowed density is 30 units per net acre which is for apartments. This project proposes 13.55 units per acre. There will be two styles of townhomes. Along the southerly border will be units that are the Village Homes which are tuck-under design to better fit the sloping topography fi`om the southerly property line. The rest of the units are Manor Homes which are split-entrys, some being walk-outs and others being look-outs. The look-out unit has the same £mished grade elevation at the rear as at the front of the unit but it functions as a look-out because the unit is a split- entry. None of the lots will be further subdivided so a future concept plan is not necessary. There are no irregular shaped lots that would require a modified unit plan to assure it will fit on the lot. The minimum separation between the buildings is 25 feet for the 4 unit buildings and 30 feet for the 6 and 8 unit buildings. The minimum setback to the adjacent property to the south is 25 feet which also is in excess of the zoning ordinance. The minimum setback to County Road No. 21 is 30 feet. The townhome units being proposed are similar to those built and being built in a number of communities in the metropolitan area which have been very-well received. These style of homes allow for more flexibility in the engineering design of the property and make it possible that the existing terrain will not have to be as massively adjusted as would be needed with an apartment building project. I am not aware ora Redevelopment Plan in this area but if there is one the proposed park area should fit very nicely into such a plan. The total ground floor area for all of the units is 126,125 square feet. This calculated to a Floor-area Ratio of 0.623. The open space calculation was made by determining the areas for Lot 53, Block 1, Lot 49, Block 2 and Lot 49, Block 3. The drainage and utility easements that are on these lots was subtracted from the areas to net an available open space area of I 15,909 sq. ii. The required open space is 600 sq. ft. per unit or 88,800 sq. ii. Attached Exhibit F is a copy of permeability tests that were taken in the area of the proposed infiltration pond. The results are that there is adequate permeability to allow storm water to seep into the soil. There will be streetlights along the private streets. There also will be a subdivision monument at the entrance from Franklin Trail. The construction will be done without phasing. It is possible that the utility construction could go into the 2003 construction season but the grading is planned to be completed in the 2002 season assuming that this approval process and the weather allow for an adequate construction season~ Westwood Professional Services, Inc. REVISED MEMORANDUM Date: July 3, 2002 From: Allan Klugman, P.E., PTOE Re: Timbercrest Park Traffic Study, Revised July 3, 2002 INTRODUCTION This memorandum summarizes the results of a traffic analysis conducted for the proposed Timbercrest Park Townhouse development in Prior Lake, Minnesota. The proposed development will contain 148 residential townhome units. The development is located south of Scott County Road 21, east of T.H. 13 and northwesterly of Franklin Trail. The site has two access points, both to Franklin Trail to the south. The remainder of this memorandum contains sections describing: · Existing Conditions · Trip Generation · Traffic Assignment · Traffic Analysis · Conclusions EXISTING CONDITIONS Westwood Professional Services collected data for, and analyzed, the two nearby signalized intersections of T.H. 13 / County Road 21 and County Road 21 / Franklin Trail. The data collection consisted of turn movement counts at each intersection for a two-hour A.M. peak period and a two-hour P.M. peak period. From these data sets the one-hour peak volumes were extracted. Figures 1 and 2 show the current A.M. and P.M. peak hour traffic counts for each intersection. With the peak hour data, Westwood conducted intersection Level of Service analysis (for signalized intersections) using the procedures outlined in The Highway Capacity Manual. The results of the Level of Service analysis are summarized below. Existing Intersection Level of Service (LOS) & Vehicle Delay Location T.H. 13 / County Road 21 County Road 21 / Franklin Trail A.M.

I LOS 10.5 B 5.7 A Memorandum: Timbercrest Park Traffic Study Revised July 3, 2002 Page 2 TRIP GENERATION The expected trip generation for the site was computed using the standard rates contained in the reference Tdp Generation, 6th Edition, 1997, published by the Institute of Transportation Engineers. The table below summarizes this trip generation. Trip Generation for 148 Townhouse Units Trips Period Rate % In - % Out In Out Total Daily 5.86 / unit 50% - 50% 434 434 868 A.M. Peak Hour 0.44 / unit 17% - 83% 11 54 65 P.M. Peak Hour 0.54 / unit 67% - 33% 54 26 80 The project property is currently zoned for apartment use. This zoning would allow 500 apartment units to be constructed on the site. As a comparison to the traffic generation for the proposed townhouses, a trip generation was also computed for the allowable apartment use. The table below summarizes the trip generation that would be dedved from the allowable 500 apartment units. Trip Generation for 500 Apartment Units Trips Period Rate % In - % Out In Out Total Daily 6.63 / unit 50% - 50% 1658 1658 3316 A.M. Peak Hour 0.51 / unit 16% - 84% 41 214 255 P.M. Peak Hour 0.62 / unit 67% - 33% 208 102 310 As shown in the above tables, the allowable apartment use Would generate almost four times as many trips as will be generated by the proposed townhouse development. TRAFFIC ASSIGNMENT The projected trip generation for the proposed townhouse development was assigned to the surrounding roadway network based on the site orientation, existing traffic patterns and judgment on the destinations of residential generated traffic in this portion of Prior Lake. It was assumed that about: · 55% of site traffic would be destined northwesterly (to T.H. 13 or County Road 21), · 35% would be destined easterly on County Road 21, and · 10% southwesterly on T.H. 13. TRAFFIC ANALYSIS To analyze the potential impacts of the Timbercrest Park development on the surrounding roadway network in the near-term future, the following future volumes were developed: existing Memorandum: Timbercrest Park Traffic Study Revised July 3, 2002 Page 3 counts increased by 10% plus Timbercrest Park traffic. Figures 3 and 4 show these volume conditions. With these volume conditions, the Level of Service for the peak periods was again computed. These results are summarized in the table below. Future (with Development) Level of Service (LOS) & Vehicle Delay A.M, Peak Hour P.M. Peak Hour Location Delay/Veh. LOS Delay/Veh. I LOS T.H. 13 / County Road 21 10.9 B 17.9 B County Road 21 / Franklin Trail 6.4 A 6.9 A CONCLUSIONS The Timbercrest Park Townhouse development will generate approximately 870 trips on a daily basis, with 65 A.M. peak hour and 80 P.M. peak hour trips. The surrounding roadway network is currently experiencing good levels of service and traffic operation. The addition of Timbercrest Park traffic will not cause impacts to the surrounding roadway network and nearby intersections. The proposed townhouse development will cause about one-quarter the amount of traffic that would be expected to be generated by the approved use of 500 apartment units. 37 (61) 222 (417) 14 (69) t 52 (50) "~ 357 (339) Jr 86 (156) County Road 21 Figure 1 Existing Peak Hour Traffic Counts xxx = A.M.

Emergency overflows must be shown on the grading plan. 2. Extraordinary erosion control measures shall be required at numerous swales on this design. 3. Show rough grading for the park (Outlot B). City staff will provide information. Sanitary Sewer 1. Provide 10" trunk sanitary sewer along Timber Crest Trail from MH8 to Franklin. City will pay for oversizing through Development Contract. 2. Show class of pipe. See Public Works Design Manual. 3. The profiles on Sheet 12 are very difficult to read (SMH1 through SMH9). Show detail of service connections to RCP. 4. Provide details on location, size and type of sewer services. There are no services shown to Lot 4, Block 1. 51 Remove the note on Sheet 11 and Sheet 14 showing sanitary sewer to be removed. This appears to be shown in the wrong location. Water Main 1. Proposed gate valves must be shown on the plan sheets. 2. Show class ofwatermain pipe as Class 52 DIP (typical). 3. Provide details on location, size and type of water services. There are no services shown to Lot 4, Block 1. 4. Lacking all watermain details: no tee, bend or valve locations or sizes are shown. G:~PROJECTS~2001 \45timbercrest~-.EVIEW3 city.doc 5. Provide hydrant details for all hydrants Storm Sewer 1. Move the low point on BluffHeights Trail so that it is not in front of any buildings - possibly in between lots 36 and 37. The entire site drains to this point. Storm drainage is concentrated in too few places; it needs to be disseminated to more catch basins. 2. Show pipe class on all RCP. (See Public Works Design Manual). 3. The streets and storm sewer system are proposed as private facilities. The storm sewer and all NURP, infiltration and quantity control drainange ponds shall be the responsibility of the homeowners association for perpetuity. A drainage and utility easement will be required on the wetland areas only. 4. See attached memorandum from WSB dated June 26, 2002 for additional comments. Streets/Sidewalk/Trail 1. Provide a trail connection to CSAH 21 through Outlot C. 2. See Plate #702 for sidewalk design requirements. 3.The streets and storm sewer are proposed as private. Drainage and utility easements should be adjusted to utility easements accordingly in areas where storm drain is collecting onsite drainage. The majority of the comments listed above can be addressed with final plat with the exception of the storm water issues, in particular Item 1 in the above Storm Sewer comments. In addition, the developer provided revised storm sewer and hydrology dated June 26, 2002. This submittal has not been reviewed to date. GSPROJECTS~2001 \45timbercrestLREVIEW3city.doc 2 & Y~t~, Inc. Memorandum Date: Re: Sue McDermott, P.E., Ci(g Engineer City of Prior Lake Andi Moffatt, Biologist WSB & Associates, Ina June 26, 2002 Review of Timber Crest Development Plans WSB Project No. 1430-02 As requested, we have completed our water resource review of the revised Timber Crest Development Plans dated June 11, 2002. Based on our review, we offer the following comments: Wetland Conservation Act (WCA) Review Comments 1. A Technical Evaluation Panel (TEP) meeting was held June 6, 2002. This meeting discussed the revised wetland impact and replacement plan received May 23, 2002. The findings of the TEP are attached. The recommendation of the TEP was to deny the WCA application based on the May 23, 2002 plans. Since that time, the developer has revised the plans to reduce the wetland impact. 2. The revised June 11th development plan and letter from SER dated June 11, 2002 shows 0.41 acres of wetland impact associated with the construction of the storm water treatment basin and grading for the townhomes. This is a reduction from the 0.87 acres of wetland proposed in the previous plan. By removing the storm water pond from the wetland to the maximum extent feasible as requested by the TEP, the developer has demonstrated adequate sequencing of avoidance and minimization based on the WCA. 3. Mitigation is proposed through the following: X Creation of 0.42 acres of New Wetland Credit (NWC) through the expansion of the existing wetland on the western edge. This wetland creation shows Sue McDermott, P.E. June 26, 2002 Page 2 of 3 irregular edges and an undulating bottom as requested by the City to the extent necessary to replace the existing functions and values of the wetland. X Creation of 0.36 acres of Public Value Credit (PVC) through the infiltration basin. As required by the WCA, the plans and letter show 75% of the one- year design pool area of the infiltration basin to be used for PVC. X Establishment of 2.21 acres upland buffer around the wetland. The WCA allows upland buffer to be used for PVC for up to 75% of the NWC area. Since the NWC area is 0.42 acres, 0.32 acres of the upland buffer can be used for PVC. The June 11, 2002 SER letter is in error as it states that 75% of 2.21 acre the buffer (1.66 acres) can be used as PVC. The WCA allows only 0.32 acres of the buffer to be used for PVC. This needs to be corrected in the wetland replacement calculations by the developer. X The creation of 0.42 acres of NWC and 0.68 acres of PVC meets the requirements of the WCA for wetland replacement for this project. 4. The sanitary sewer and other utilities need to be shown on the grading plans. 5. The revised wetland replacement information was received on June 12, 2002; therefore, the 60-day timeline for the City to make a detennination regarding the WCA application ends August 9, 2002. 6. The landscape plan (sheet 6) does not match the grading plan. This needs to be corrected by the developer. 7. The mitigation and infiltration basin seeding information needs to be shown on the plans. Hydrologic/Hydraulic, Water Quality, and Grading Comments 1. Additional catch basins should be placed behind Lots 8 and 16 on Block 3, Lot 8 on Block 1, and Lot 1 on Block 2. 2. The minimum grade for drainage swales and lot grading must be 2% or greater in accordance with the City's 2002 Public Works Design Manual. 3. The storm sewer should be expanded on Bluff Heights Trail in front of Block 1 to include two additional catch basins at station 3+00. 4. Additional catch basins to Timber Crest Drive should be included on the plans. G:lPROdECTSI200II45timbercrestlO62602smTC. doc Sue McDermott, P.E. June 26, 2002 Page 3 of 3 5. The text Note 11 on page 5 should be changed from 3:1 to 4:1 in accordance with the City's 2002 Public Works Design Manual. 6. The city should consider requesting that pipes be added to the inlet of the skimmer structures. By extending pipes from the base of the skimmers and adding fill on top of the pipes, the result would be a much more aesthetically pleasing structure. In addition to this, there would be less accumulation of debris at the base of the structure. 7. Please add spot elevations to the overflows between lots 40, 41, 36 and 37, on Block 1 in order to illustrate that there is 1' of freeboard between the overflow and the building pad. 8. The city should evaluate whether increased access to the maintenance bench and outlet structures is needed. This concludes our review of the Timber Crest Development plan.

Sincerely, Craig Jenson Transportation Planner March 21, 2002 Jane Kansier City of Prior Lake 16200 Eagle Creek Avenue Prior Lake, MN 55372 RE: Preliminary Plat, Timber Crest Franklin Trail and TH 13 Dear Jane: We have reviewed the preliminary plat as it relates to Highway Department issues and offer the following comments or concerns: The development is proposing an access onto CSAH 21. It is County policy that when there is more than one public roadway to serve the property, access shall be taken from the lower function or lower volume roadway. Franklin Trail is the lower function/volmne road and Franklin Trail also provides a controlled intersection with CSAH 21. CSAH 21 is designated as Minor Arterial. It is our responsibility to preserve mobility along Minor Arterials as best we can. Traffic on CSAH 21 is over 14,000 vehicles per day and providing more access to CSAH 21 in this area would create more conflicts on the road, and could therefore have an effect on the safety of motorists using CSAH 21. · With the need for additional improvements such as tom lanes at CSAH 21 and TH 13 and CSAH 21 at Franklin Trail, we recommend 75 feet of right-of-way be dedicated. · No ponding, berming, or landscaping shall be permitted within the County right-of-way. Utility permit shall be required for any work within the County right-of-way. · Any change is drainage entering the County right-of-way shall require detailed stormwater calculations to be submitted to the County Engineer for review and approval.

The property was initially served with sewer and water utilities in the early 1960's. Under the original assessment roll this property was assessed for sewer and water lateral charges only. Since utilities are available to the property site, the cost for the extension of services internally will be the responsibility of the developer. In 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 $1685.00/unit if partial park land dedication $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 13.64 acres of townhouse units (includes net deduction of 14.55 acres for street and wetlands row.) as provided within the site data summary sheet of the preliminary plat. Collector Street Fee: 13.64 acres ~ $1500.00/ac = $20,460.00 Storm Water Management Fee: 13.64 acres ~ $2943.00/ac -- $40,143.00 Trunk Sewer & Water Charge: 13.64 acres ~ $3500.00/ac = $47,740.00 Assuming the initial net lot area of the concept plan does not change, the above referenced collector street, stormwater 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. 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.
