The subject site is located south of County Highway 42, west of Ferndale Avenue, and north of Lower Prior Lake. History The City has received multiple land use applications for potential development of this site over the last several years. In 2013 the City Council denied an application for a preliminary plat on the east half of the site. In 2014 the Pulte Group submitted a concept plan and preliminary plat to the City but ultimately withdrew the application due to financial feasibility. More recently the Pulte Group submitted a concept plan to the City in early 2017. The Planning Commission and City Council provided feedback on the concept plan, and the Pulte Group has since moved forward with this current Preliminary Plat and PUD application. The Planning Commission held a public hearing on May 1, 2017 and received several comments from the public (see attached minutes of the meeting). The main comments highlighted concerns with traffic, drainage, and the integration of a street/utility project on Rolling Oaks Circle. Current Circumstances The current proposal calls for a 207-lot single family subdivision and PUD on the site with a mix of housing product types and lot sizes. The area encompasses land with wooded areas to the north, a large significant wetland, and open field areas in the south. The following paragraphs outline the physical characteristics of the existing site, the Comprehensive Plan and zoning designations, and a description of some of the specifics of the site. PHYSICAL SITE CHARACTERISTICS: Total Site Area: The total development site area consists of approximately 92 acres which includes a large amount of what is known as the Shepard/Griffith and Bolger properties. Topography: This area has varied topography with area elevations ranging more than 50 feet from the 920’ MSL along the eastern property line near the City park land to 970’-980’ MSL at a few high points throughout the property. Wetlands: Several small wetlands and one large high-quality wetland exist on the proposed site. The developer proposes some impacts to the small wetlands which will be evaluated under the regulations of the Wetland Conservation Act. Access: The main access to the site is currently from a single gravel driveway at County Hwy 42 that is identified as Meadowlawn Trail. 2030 Comprehensive Plan Designation: This property is designated for Low Density Residential uses on the 2030 Comprehensive Plan Land Use Map. Zoning: The site is presently zoned R-1, Low Density Residential. PROPOSED PLAN Phasing: The developer expects to complete this project in three phases, beginning in 2017 and potentially ending in 2018 or 2019. The phasing plan and the attached narrative identifies the 3 phases. A mixture of housing types is proposed for construction in the first 2 phases. Lots: The development plan calls for 207 lots to be constructed of single family housing styles. The lot sizes range in size and product type including 90 multi- story single family detached homes, 2) 52 one-story single family detached homes, and 3) 65 3-story attached townhome units. Requested PUD modifications to the typical lot minimum sizes and widths are as follows: Min. Lot Area Min. Lot Width Multi-Story Single Family 7,559 sq. ft. proposed (12,000 sq. ft. required) 60 feet proposed (86 feet required) One-Story Single Family 7,559 sq. ft. proposed (12,000 sq. ft. required) 55 feet proposed (86 feet required) Density: Density of the development is based on the net area of the site, which is approximately 61 acres. There are a total of 207 units proposed, for an overall density of approximately 3.4 units per acre. This is consistent with the density in the R-1 district. Building Setbacks: The developer requests PUD modifications to the building setbacks as follows: Townhome Setbacks Required (R-1 Zoning) Proposed Front (private street) 25’ from back of curb 20’ Front (from public street) 25’ from ROW line 20’ Side (between buildings) 20’ 20’ * The developer does not propose modifications to the require typical R-1 building setbacks for the multi-story single family lots Parks / Trails: Parkland dedication is proposed mainly around the high-quality wetland at the center of the development with some additional open space adjacent to the current City Park (North Shore Park) along the eastern property line as Outlot K. While Outlot K does include areas greater than the standard 10% maximum slope for useable active parkland, this area provides additional open space adjacent to the existing public park/open space of North Shore Park and nearby wetland. A network of public trails and sidewalks are proposed throughout the site including connections to existing regional trails, a paved trail around the large wetland, and a curvilinear sidewalk network as part of the site design. A playground feature area is envisioned at the southwest corner of the large wetland. Tree Replacement: There are many significant trees on this site particularly in the north half of the site. Due to the need to install street and public utility connections throughout the ever-varying existing topography, it is difficult to preserve many tree areas with the exception on the site perimeter and around the large wetland. The developer has prepared an extensive landscape plan which will incorporate over 860 trees (2,600 inches) of replacement on the private lots, outlots, parkland, and street center islands in accordance with our tree replacement ordinance. Access/Street: The developer proposes a variety of local and collector streets. These streets include the “missing link” of Carriage Hills Parkway which is an important east-west collector that is proposed to be completed at one time with the 2nd phase. It’s also important to note that the development plan shows only one connection of Meadowlawn Trail into Carriage Hills Parkway as recommended by City Staff. Meadowlawn Trail is an important connection through the development from Carriage Hills to County Highway 42 with limited driveway access points. Although City staff would recommend even fewer driveway accesses, the plan shows turn-around potential for each driveway that abuts this street (which acts as a minor collector). Moreover, the road appears to properly align with the future full intersection at County Highway 42. A traffic calming round-about is proposed at the intersection of Meadowlawn Trail and Carriage Hills Parkway. Also, private streets are proposed for the townhome area at the northeast corner of the development. After taking comments at the public hearing, the Planning Commission recommended the developer consider One-Story Single Family Required (R-1 Zoning) Proposed Front 25’ 25’ Side 10’ 5’ / 10’ Rear 25’ 20’ expanding the Ferndale Avenue street width and install curb/gutter along the street. Sanitary Sewer / Water Mains: Sanitary sewer and watermain service will be extended from multiple existing lines in the region. These include connections to sanitary sewer lines under Carriage Hills Road, Ferndale Avenue, and County Hwy 42 (via Rolling Oaks Circle). Watermain connections are proposed to Carriage Hills Road, Ferndale Avenue, and multiple connections to County Hwy 42 (one connection via Rolling Oaks Circle). Shoreland District/Impervious Surface: The maximum impervious surface allowed in the Shoreland District is 30% of the lot area. Impervious surface coverage is further limited to 25% of each tier area in a Shoreland District PUD. The only area within the shoreland district (within 1000 feet of Prior Lake) is the area at the southeast corner of the development just north of Carriage Hills Parkway. This tier area will meet the shoreland district impervious surface requirement. Grading / Storm water: The site is very complex from a grading and storm water perspective. The developer proposes to grade the entire site prior to the construction of the first phase because of all the street, utility, and storm water features which are ultimately planned. Multiple storm water basins are proposed, and the City Staff has recommended increased regionalization of storm water basins on the site. Fees and Assessments: This development will be subject to the standard development fees including park dedication and trunk street and utility service charges. The developer installed street improvements are substantial and as a part of the PUD, the developer is offering to install the full street improvements as an offset to the City charging the street oversize fee for this development. City Staff has evaluated the street costs and concludes that this fee will be satisfied given the proposed regional street improvements and PUD benefits that are being proposed at the developer’s sole cost. Conclusion The Trillium Cove development, as proposed, is a very complex and unique project. The developer and City Staff have met numerous times to discuss the many aspects of the site. The developer has also hosted a neighborhood meeting to present the development plan to nearby property owners. City Staff believes the developer is identifying unique PUD benefits within the site including the preservation of a high quality large wetland and creating a natural public open space around this feature with an area for a park structure in the future. Mixed used housing is also proposed for the site, and an innovative residential development design that includes curvilinear streets, varying building angles and setbacks, and a unique sense of place for future residents. In addition, the City is considering an option to coordinate reconstruction of Rolling Oaks Circle street and utility improvements along with the developer’s utility construction in the area. Although the status may change, at this time no commitments have been made by the City Council to this effort and the developer is planning to proceed without coordination of a City reconstruction project. As noted in the attached staff memorandums, the developer must refine the plans to assure compliance with the Public Works Design Manual requirements and City Zoning Ordinance; however, City Staff has discussed these comments with the developer, and City Staff feels they will not drastically alter the design of the development plan or preliminary plat. Therefore, City Staff does propose that the City Council approve the Trillium Cove Preliminary Plat and PUD Plan with the following conditions: • The developer shall revise the plans according to the April 21, 2017 City Engineering & Public Works Dept. Memorandum • The developer shall revise the plans according to the May 15, 2017 City Community Development Dept. Memorandum • The developer shall obtain a grading permit from the City Engineering Department prior to any grading or tree removal on the site. • The Developer shall obtain the required permits from other state or local agencies prior to applicable on the site ISSUES: PUD’s provide a flexible approach to development that allows creative, efficient and effective use of land, including the mixing of land uses. The proposed project includes a mix of housing types and lot sizes. A PUD tends to preserve more unique features on site and provides more open space. Despite smaller lots and townhomes in this plan, the overall net housing density remains low (3.4 units per acre). The PUD must be reviewed based on the criteria found in Section 1106 of the Zoning Ordinance. The criteria which are applicable to the Trillium Cove PUD are discussed below: (1) Provides a flexible approach to development which is in harmony with the purpose and intent of the City's Comprehensive Plan and Zoning Ordinance. The proposed PUD is consistent with the Comprehensive Land Use Plan designations on the entire site. The PUD approach allows the location of the different land uses in ways that preserve and enhance the natural features of the site. (2) More creative, efficient and effective use of land, open space and public facilities through mixing of land uses. The proposed PUD plan clusters the residential areas, and provides over 37% of open space on the site. (3) Create a sense of place and provide more interaction among people; The PUD plan proposes trails, and other pedestrian elements to connect the residential elements. A unique and innovative site design incorporates varying building setbacks, increased safety views at street intersections, and better view corridors that enhance the pedestrian and vehicular experience as residents navigate the development. (4) Increase transportation options, such as walking, biking or bussing; The plan includes a network of trails that will connect to the regional trail system. A trail around the large wetland provides a unique natural walking/biking experience as well. The developer also proposes 10 parallel parking stalls along the east side of Meadowlawn Trail adjacent to the proposed City park land. (5) Provide opportunities for life cycle housing to all ages. The PUD plan includes several housing types, including one-story single family dwellings, attached multi-story townhouses, and multi-story traditional single family homes. This mix will provide housing options to many different buyers. (6) Provide more efficient and effective use of streets, utilities, and public facilities that support high quality land use development at a lesser cost. The development utilizes a mix of public and private streets. The public streets provide access through the development and to connectivity to adjacent areas. The private streets are used for the townhome development, and will be maintained by a homeowners’ association. (7) 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 PUD district also 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. The PUD incorporates preservation of a large natural trail system around the wetland area, as well as an active park location nearby the wetland feature. The developer proposes parkland dedication over and above the necessary requirement of 10% of the site area. (8) Preserves and enhances desirable site characteristics and open space, and protection of sensitive environmental features including, but not limited to, steep slopes, wetlands, and trees. Where applicable, the PUD should also encourage historic preservation, re-use and redevelopment of existing buildings. The plan includes a trail around the high-quality wetland as well as preservation of the wetland itself as a focal point within a public park, curvilinear sidewalks, and a system of trails connecting to other trails in adjacent developments to create a unique and innovative pedestrian experience. (9) High quality of design compatible with surrounding land uses, including both existing and planned. The proposed design is compatible with the surrounding low density residential land uses.

The PUD is a single-family development consisting of 207 lots for single family homes. The PUD plan provides a minimum of 12.5 acres of park to be dedicated to the City. b. The total number of units on the site will not exceed 207. c. As part of the park development, the developer is responsible for grading, topsoil, turf establishment and construction of the trails to the specifications provided by the City as indicated on the approved PUD plans. d. The elements of the plan will be as shown on the plans dated May 3, 2017, except for modifications approved as part of the final PUD plan. 4. It hereby adopts the following findings: a. Provides a flexible approach to development which is in harmony with the purpose and intent of the City's Comprehensive Plan and Zoning Ordinance. The proposed PUD is consistent with the Comprehensive Land Use Plan designations on the entire site. The PUD approach allows the location of the different land uses in ways that preserve and enhance the natural features of the site. b. More creative, efficient and effective use of land, open space and public facilities through mixing of land uses. The proposed PUD plan clusters the residential areas, and provides over 37% of open space on the site. c. Create a sense of place and provide more interaction among people; The PUD plan proposes trails, and other pedestrian elements to connect the residential elements. A unique and innovative site design incorporates varying building setbacks, increased safety views at street intersections, and better view corridors that enhance the pedestrian and vehicular experience as residents navigate the development. d. Increase transportation options, such as walking, biking or bussing; The plan includes a network of trails that will connect to the regional trail system. A trail around the large wetland provides a unique natural walking/biking Page 5 experience as well. The developer also proposes 10 parallel parking stalls along the east side of Meadowlawn Trail adjacent to the proposed City park land. e. Provide opportunities for life cycle housing to all ages. The PUD plan includes several housing types, including one-story single family dwellings, attached multi-story townhouses, and multi-story traditional single family homes. This mix will provide housing options to many different buyers. f. Provide more efficient and effective use of streets, utilities, and public facilities that support high quality land use development at a lesser cost. The development utilizes a mix of public and private streets. The public streets provide access through the development and to connectivity to adjacent areas. The private streets are used for the townhome development, and will be maintained by a homeowners’ association. g. 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 PUD district also 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. The PUD incorporates preservation of a large natural trail system around the wetland area, as well as an active park location nearby the wetland feature. The developer proposes parkland dedication over and above the necessary requirement of 10% of the site area. h. Preserves and enhances desirable site characteristics and open space, and protection of sensitive environmental features including, but not limited to, steep slopes, wetlands, and trees. Where applicable, the PUD should also encourage historic preservation, re-use and redevelopment of existing buildings. The plan includes a trail around the high-quality wetland as well as preservation of the wetland itself as a focal point within a public park, curvilinear sidewalks, and a system of trails connecting to other trails in adjacent developments to create a unique and innovative pedestrian experience. i. High quality of design compatible with surrounding land uses, including both existing and planned. The proposed design is compatible with the surrounding low density residential land uses. Provides a flexible approach to development which is in harmony with the purpose and intent of the City's Comprehensive Plan and Zoning Ordinance. The proposed PUD is consistent with the Comprehensive Land Use Plan designations on the site and the Zoning Ordinance. j. More creative, efficient and effective use of land, open space and public facilities through mixing of land uses. The proposed PUD plan allows for the preservation of open space, as well as park and trails. k. Create a sense of place and provide more interaction among people. Page 6 The PUD plan provides for a trail to allow connections to the adjacent properties for possible future recreational opportunities. l. Increase economic vitality and expand market opportunities; The proposed variety of housing styles will provide additional housing opportunities. m. Support long-term economic stability by strengthening the tax base, job market and business opportunities; The new development will strengthen the City’s tax base. n. Increase transportation options, such as walking, biking or bussing; The plan will provide an extension of the City trail system. o. Provide opportunities for life cycle housing to all ages. The PUD plan will provide another option for housing and is appropriate for this location. p. Provide more efficient and effective use of streets, utilities, and public facilities that support high quality land use development at a lesser cost. The PUD will have a private street that will be maintained by the homeowners association. q. 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 PUD district also 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. The PUD dedicates 2.14 acres to the City to incorporate park area, open space, and trails. r. Preserves and enhances desirable site characteristics and open space, and protection of sensitive environmental features including, but not limited to, steep slopes, wetlands, and trees. Where applicable, the PUD should also encourage historic preservation, re-use and redevelopment of existing buildings. The PUD will be restoring a prairie savannah on the east side of the development. s. High quality of design compatible with surrounding land uses, including both existing and planned. The proposed PUD is compatible in respect to product type of the single-family homes to the north and south and in respect to the density of the twin home development to the west. 5.

Pulte’s company vision is “Building Consumer Inspired Homes and Communities to Make Lives Better”. We are nationwide company with a corporate office in Atlanta, Georgia. We currently operate under three distinct brands of homebuilding throughout the country: Pulte Homes, Centex Homes, and Del Webb. Pulte’s Minnesota Division has an office in Eden Prairie and will sell approximately 450 homes in the Twin Cities in 2017. We take pride in offering very popular floor plans, creating innovative neighborhoods, and working with integrity. Pulte will act as both developer of the property and builder of the homes within Trillium Cove. The primary contact for Pulte is: Paul Heuer, Director of Land Planning & Entitlement 7500 Office Ridge Circle, Suite 325 Eden Prairie, MN 55344 952-229-0722 Paul.Heuer@PulteGroup.com The owners of the property are: Meadowlawn Development Corporation Charles and Richard Bolger 14560 Trillium Cove Trail NE Prior Lake, MN 55372 612-750-9942 cbolger@bolgerinc.com Lot 1 Partnership Sue Griffith C/O Mr. Brian Pankratz LaSalle Plaza 8000 LaSalle Avenue, Suite 1900 Minneapolis, MN 55402 952-924-4665 Brian.pankratz@cbre.com 2 Legal Description SECTION 25 TOWNSHIP 115 RANGE 022 P/O W1/2 NW1/4 COM SW COR NW 1/4, N 303.93' TO POB.

The Last Puzzle Piece Trillium Cove sits among fully developed neighborhoods to the east and west. County Road 42 lies along the northern border of the property. Carriage Hills Parkway, upon completion, will act as the southern border of the property. Trillium Cove is a true infill development which substantially completes development in this area. Site Attributes & Constraints The property contains a number of beautiful attributes which also pose development constraints. The north half of the property contains woods, scattered wetlands, and steep, rolling hills. The entire property has complex drainage patterns which release storm water in various directions. The complex drainage patterns have been dealt with through detailed civil engineering strategies. The woods and wetlands pose both constraints and opportunities in creating a vision and innovative concept plan for this new neighborhood. Property Recent History This property is complicated to develop for a variety of reasons outlined elsewhere in this narrative. For the past 15 to 20 years developers have been attempting find a way to successfully develop the property. We believe it is important to describe the most recent applications. Both the 2013 and 2014 applications failed due to the various complexities and related costs. K Hovnanian Preliminary Plat Application (2013) In 2013, builder/developer K Hovnanian submitted an application for preliminary plat for the east half of the property. The City Council ultimately denied this application. Pulte Homes Concept Plan Application (2014) In 2014, Pulte Homes submitted an application for concept plan review with standard R-1 zoning for the west half, the east half, and some property along Prior Lake. The application was received very well by City staff, the Planning Commission, and the City Council. Pulte Homes Preliminary Plat Application (2014) In 2014, Pulte Homes submitted an application for preliminary plat with standard R-1 zoning for the west half, the east half, and some property along Prior Lake. Unfortunately, Pulte Homes withdrew the application shortly thereafter due to lack of financial feasibility. It should be noted that the name of the 3 community with this application was “Meadowlawn”. The sellers recently requested that we change the name so that their remainder property could retain this historic family name. Pulte Homes Concept Plan Plat Application (2017) In 2017, Pulte Homes submitted an application for concept plan with PUD zoning. The application was received very well by City staff, the Planning Commission, and the City Council. Please note that the name “Griffith Woods” was used for this application. Pulte Homes Neighborhood Meeting (2017) In 2017, Pulte Hom es held a neighborhood meeting to present the concept plan and received feedback. Many questions were fielded, primarily dealing with traffic and potential future Rolling Oaks Circle improvements. Neighborhood Vision As we set upon the task of creating a new neighborhood, it was important to us to utilize the beautiful natural features of the Trillium Cove property and to showcase them. We worked hard to incorporate the wetlands, woods, and rolling hills. Our vision for Trillium Cove incorporates the following high level goals: 1. Appeal to a variety of demographic groups – We have found that a neighborhood with housing that appeals to a variety of demographic groups has more vitality and energy which is very attractive to residents. See “Homes” section of this narrative for more details on the homes. 2. Showcase the wonderful natural amenities – Although standard engineering design requirements limit our ability to preserve natural amenities, we recognized that we could focus preservation efforts in high visual impact areas. 3. Innovative site design - We hired Rick Harrison Design Studio, a nationally renowned design firm to create an innovative design which would blend our goals, the City’s goals and his own creative design process. 4. Street connectivity and pedestrian orientation – Due to the infill nature of this property, there are numerous opportunities to make street and trail/sidewalk connections which complete multiple transportation networks. Of particular importance is completing the last section of Carriage Hills Parkway , connecting County Road 42 with Carriage Hills Parkway, and creating pedestrian connections between County Road 42, the beautiful wetland in the central part of this property, Carriage Hills Parkway, North Shore Oaks Park, and Sandpoint Beach. City Goals We monitored the K Hovnanian application in 2013 and listened closely to what was liked as well as disliked by the City. Through our 2014 application process we also learned a great deal about City goals for this particular property and region of the City. Here is a summary of the goals that we heard strongly and consistently expressed by the City for the Trillium Cove property: 1. Develop the two properties together 2. Street and pedestrian connectivity 3. Build Carriage Hills Parkway 4. Limit access to Carriage Hills Parkway 5. Build the north/south collector street 6. Preserve the large, high quality wetland 7. Build a public trail around the large wetland 8. Provide space for a new public park near the large wetland 4 In creating this new neighborhood, our goal was to satisfy all of the above listed City goals and to incorporate them into the Pulte neighborhood vision. Innovative Design Pulte Homes is known for the extraordinary steps that we take to ensure that we are designing and building homes that meet the needs and desires of home buyers (see “Our Homes” section of this narrative). We also focus intently on designing neighborhoods that are beautiful and pleasant to live in. As such, we have hired nationally renowned neighborhood designer Rick Harrison Design Studio. Rick Harrison has invented several planning methods and created specialized software used in land planning across the country. He continues to refine the cutting edge, innovative design approach previously known as “coving”. Pulte Homes utilizes Rick’s specialized skills because we find great value in creating innovative and beautiful neighborhoods that have the following positive attributes: 1. Attractive from the Outside – While driving past many neighborhoods, drivers see a row of homes with the rears facing the perimeter street. Typically, the rears of homes are the least attractive sides. In addition, homes tend to look similar when they are lined up in a row. From our standpoint, this first impression of a new neighborhood is not as strong as it could be. With Trillium Cove, drivers on County Road 42 and Carriage Hills Parkway will see open space, woods, view corridors, and primarily fronts and sides of homes. Through this intentional design strategy, Trillium Cove will leave a positive and lasting impression on the eyes of the public. 2. Attractive Driving Through – It is very common in traditional neighborhoods to see straight streets with homes set back from the streets at the same distance. This type of uniformity makes it difficult to create an attractive neighborhood. A Rick Harrison neighborhood typically has curvilinear streets and varied home setbacks from the street. This creates a feeling of spaciousness while driving down the street. It also creates a feeling of constant variation, interest, and beauty. Another design strategy that Rick incorporates is “view corridors”. Instead of lining both sides of the primary streets with homes, Rick is adept at placing the streets next to wetlands, ponds, and woods, thereby creating beautiful view corridors for the driving public. Bringing natural beauty continuously into view creates a strong feeling of quality, beauty, timelessness, and the integration of nature into a neighborhood. 3. Better Views from Within the Homes – The curvilinear streets and varying home setbacks result in the homes having different orientations with respect to each other. In other words, the homes are not lined up side by side. This varying orientation creates more and better views from inside the homes to the surrounding areas, thereby bringing additional beauty and value to the homeowners. After many iterations through the Concept Plan stage, we are very pleased with the outcome of the neighborhood design. It satisfi es all identified City goals, integrates nature into the neighborhood, and provides a variety of housing types within one master planned community. We are particularly pleased with the elements of beauty: • A strong sense of entry • Buffers around the perimeter of the neighborhood, many of them wooded • Curv ilinear streets • View corridors while driving After the Concept Plan was presented to and reviewed by the City, we undertook engineering design of the neighborhood. We are pleased to report that the overall layout is nearly identical to the Concept Plan. Revisions have been very minor in scope. 5 Key Facts • Addresses of property: 14175 Rolling Oaks Cir NE, Prior Lake, MN 55372 for the property in the northwest corner.

We continually reach out to the public and Pulte homeowners to get feedback to improve our home designs. It is what we call Life Tested®. We actually build prototypical rooms and homes in warehouses across the country and pay members of the public to walk through and provide written feedback on the homes. Through this intensive process, we have conceived of and incorporated many innovative features such as the Pulte Planning Center, the Everyday Entry, Super Laundry, Oversized Pantry, and the Owner’s Retreat. This exhaustive process has played a major part in Pulte’s success in “Building Consumer Inspired Homes and Communities to Make Lives Better”. One of the primary goals in creating our vision for Trillium Cove is to provide different housing products that would appeal to a variety of demographic groups. As mentioned earlier, we have found that a neighborhood with housing that appeals to a variety of demographic groups has more vitality and energy. We will be building three different types of homes that are designed to appeal to different demographic groups. Each is described briefly below. Attached you will find example front elevations of each housing product. 6 Single Family Homes This property is located within the celebrated Prior Lake-Savage Area School District. Strong school districts are highly desirable to families. We anticipate that there will be strong demand for our single family homes which will be in the anticipated range of the mid-$300k’s to the high-$400k’s. Single family homes will be located in the northwest and southeast parts of the neighborhood. Single Level Homes We commonly hear that cities are learning that they do not have adequate housing to serve the empty nest population. Many of these homebuyers raised their families in your community, volunteered, are invested heavily in the larger community, and are now ready to move into a smaller, single level home. Many cities express a concern that these residents will move out of their communities due to a lack of adequate housing. Trillium Cove will offer the single level homes with lawn maintenance and snow removal for which these buyers are looking. Although not age restricted, we anticipate that the primary buyers of these homes will be couples or singles age 55 or older. We anticipate the single level home prices to range from the low-$300k’s to the low $400k’s. Single level homes will be located in the southwest part of the neighborhood and along the north side of the large wetland. Townhomes We will be building townhomes in Trillium Cove which will have an attainable entry price and will also provide association maintained lawn, snow removal, and building exterior maintenance. This type of home appeals to many singles and first time home buying families. We anticipate the townhome prices to range from the low-$200k’s to the high $200k’s. Townhomes will be located in the northeast part of the neighborhood. Parks & Trails The City has expressed a strong interest in creating a neighborhood park within the open space in Trillium Cove. We support this approach and the amount of land that we are dedicating to the City is plentiful for this use. In addition, there are a number of trails connections that are desired through the new neighborhood. We have planned to construct all of these trails. Required Park Dedication Ordinance 1004.1000 outlines the park dedication requirements for each development: 10% of net area calculated as gross area less storm water outlots, wetland outlots, major right-of -way dedication. Below is a calculation of net area: 7 Therefore, park dedication is required to be 10% of 61.95 acres = 6.195 acres of land. Actual Park Dedication We have consistently heard that the City would like us to preserve the large, high quality wetland in the central portion of the property, to retain some woods surrounding it, and to build a public trail around the wetland. We have designed the neighborhood to accomplish these goals and have designed trails and trail connections that are consistent with the City’s Comprehensive Plan. Our park dedication requirements will be more than fulfilled by a combination of park/open space land dedication around the large wetland, park/open space land dedication adjacent to North Shore Oaks Park, construction of various public trails shown on the City Comprehensive Plan within Trillium Cove, and construction of park parking stalls. 1. Land – We will be dedicating the following outlots to the City: a. Outlot L – 11.73 gross acres – 5.55 acres wetland = 6.18 acres of upland woods, open space, and park land b. Outlot K – 1.86 gross/net acres of upland woods, open space and park land; 0.40 acres of the 1.68 acres is undisturbed and primarily wooded Total upland dedicated to the City will be 8.04 acres, exceeding the required 6.195 acres by 1.845 acres. The value of the additional land dedicated to the City is 1.68 acres x $110k/net acre = $203,000. 2. Trails – We will construct all of the public trails shown on our application. We estimate the construction cost of this work to be $280,000. 3. Park Parking - Our design accommodates the future City construction of a tot lot along Meadowlawn Trail. We show an illustrative example on our submittal drawings which demonstrates a logical location for the tot lot. We also included an example photo below which shows a typical tot lot design. As part of our infrastructure work, we will be constructing ten parallel “bay” style parking stalls along Meadowlawn Trail to serve the future tot lot. The estimated cost of this park parking is $30,000. Total land dedication, public trail construction, and park parking construction exceeds the City park dedication ordinance requirements by approximately $513,000. We request that the City construct the tot lot in 2018. Infrastructure As an infill development, public infrastructure is available at or near the perimeter of the property in multiple locations. A substantial part of Trillium Cove will be served by a sanitary sewer currently at the intersection of County Road 42 and Rolling Oaks Circle, northwest of the property. We will connect to this sewer, extend the sewer down part of Rolling Oaks Circle, and then extend the sewer into Trillium Cove. This sewer 8 extension and the associated restoration of the gravel street will be completed and funded by Pulte Homes. We have worked in detail with City staff to compose conditions of approval for Trillium Cove which provide for a potential City reconstruction project of Rolling Hills Circle, if desired by the City Council. It should also be noted that due to this property being “the last puzzle piece”, an inordinate amount of regional transportation improvements are desired by the City and County to be constructed in conjunction with development of Trillium Cove. These regional transportation improvements (shown in red in the below graphic) include: 1. Construction of the last section of Carriage Hills Parkway, which will create a continuous connection between County Road 42 and County Road 21. 2. Construction of a collector road connecting County Road 42 with Carriage Hills Parkway. 3. Reconstruction of the intersection of County Road 42 and the new collector road, resulting in a new full access intersection serving this region. 4. Reconstruction of the intersection of County Road 42 and Rolling Oaks Circle, thereby creating a right in right out limited access intersection. 5. Reconstruction of the intersection of County Road 42 and Ferndale Avenue, thereby creating a right in right out limited access intersection. Although these improvements benefit a much broader area than the Trillium Cove neighborhood, and some of the improvement provide no benefit to Trillium Cove (#4 and #5), Pulte Homes is planning to complete all of these regional transportation improvements at significant expense. The City has traditionally charged developers a “Street Oversize Acreage” fee. The purpose of this fee is to fund regional transportation improvements in a fair manner. For instance, it would not be fair for the first developer in an area to pay the entire cost of a regional roadway. Similarly, it would not be fair for the last developer in an area to pay the entire cost of a regional roadway. However, in the case of Trillium Cove, the fee does not work. We happen to be the last developer in an area and we are required to pay for an abundance of regional transportation improvements, many of which do not even benefit Trillium Cove. The estimated net amount of this fee for Trillium Cove is $225,000. The estimated cost of the desired regional transportation improvements is $1,100,000 (see details below). We realize that the City has a strong interest in having these regional transportation improvements constructed in conjunction with development of Trillium Cove. Therefore, we are proposing to construct all of the improvements outlined below at Pulte’s cost. The value of the regional transportation improvements in excess of the potential fee is $875,000. We request that construction of these regional transportation improvements satisfies our “Street Oversize Acreage” fee. 9 Shoreland District A small part of the southern portion of Trillium Cove lies within the shoreland district for Prior Lake. The purpose of shoreland district requirements is to protect the quality of nearby surface waters. In this particular case, requirements are satisfied by having all storm water within the shoreland district infiltrate into the ground and therefore will not reach Prior Lake. Planned Unit Development (PUD) Traditionally, PUD zoning is utilized to preserve natural topographic features and to provide win-win situations for cities and developers. In this particular case, due to the fact that this is “the last puzzle piece”, the City will obtain a great deal: 1. A beautiful new neighborhood which… 2. Serves various demographic groups 3. The two properties will be developed together as one 4. Sanitary sewer will be installed through half of Rolling Oaks Circle at no City cost 5. Pedestrian connectivity and new public trails 6. Carriage Hills Parkway finally completed 7. A round-a-bout on Carriage Hills Parkway to calm traffic speeds 8. Limited access to Carriage Hills Parkway 9. North/south collector street connecting Carriage to County Road 42 10. County Road 42 improvements at collector street 11. County Road 42 improvements at Rolling Oaks Circle 12. County Road 42 improvements at Ferndale Avenue 13. Trunk water main connection beneath Carriage Hills Parkway 14. Preservation of most wetlands, including the large, high quality wetland 15. 6.19 acres of publicly dedicated woods/open space around large wetland w/trail 16. The above referenced public space is adequate in size to accommodate a park/tot lot 17. 1.68 acres of publicly dedicated woods/open space adjacent to North Shore Oaks Park 18. Landscaped islands 19. Professionally managed HOA’s 20. $500,000 in value of additional land, trails, park parking above and beyond park dedication requirements 21. $1,100,000 of regional transportation improvements in lieu of $225,000 of street oversize fees With a PUD, Pulte will receive the benefit of being able to create a beautiful new neighborhood that serves multiple demographic groups, preserves trees and wetlands, and contains modern lot sizes. Phasing & Schedule Following is a summary of our preliminary schedule for development: May 1, 2017 City Council potentially approves rezoning, preliminary PUD May 22, 2017 City Council potentially approves rezoning, preliminary PUD July 10, 2017 City Council potentially approves 1st Addition final plat Summer/fall 2017 Site development work January 2018 Begin selling homes 2021 Full development buildout We anticipate developing Trillium Cove in three construction phases as outlined in the attached preliminary Phasing Plan. Grading of all phases will be completed with Phase 1. 1 PRIOR LAKE PLANNING COMMISSION MINUTES Monday, May 1, 2017 1. Call to Order and Pledge of Allegiance: Commissioner Fleming called the Monday, May 1, 2017 Prior Lake Planning Commission meeting to order at 6:00 p.m. Those present were Commissioners Bryan Fleming, Dave Tieman, Mark Petersen, William Kallberg and Dan Ringstad. Also present were Liaison Zach Braid, City Planner Jeff Matzke, Development Specialist Casey McCabe, Engineer Larry Poppler, Project Engineer Monserud and Development Services Assistant Sandra Woods. 2. Approval of Agenda: MOTION BY RINGSTAD, SECONDED BY PETERSEN TO APPROVE THE MONDAY, MAY 1, 2017 PRIOR LAKE PLANNING COMMISSION AGENDA. VOTE: Ayes by Fleming, Tieman, Petersen, Kallberg and Ringstad. The Motion carried. 3. Approval of Monday, April 17, 2017 Meeting Minutes: MOTION BY PETERSEN, SECONDED BY KALLBERG TO APPROVE THE MONDAY, APRIL 17, 2017 PRIOR LAKE PLANNING COMMISSION MEETING MINUTES. VOTE: Ayes by Fleming, Tieman, Petersen and Ringstad. Abstained by Kallberg. The Motion carried. 4. Public Hearings: A. PDEV17-000003 – Trillium Cove – Preliminary Plat and Preliminary Planned Unit Development – Pulte Homes of Minnesota, LLC is proposing a preliminary plat and preliminary planned unit development (PUD) plan for a single family residential subdivision. The subject property is located south of County Road 42, north of Lower Prior Lake, east of Rolling Oaks, and west of Ferndale Avenue NE. PID’s: 250520130, 259250272 and 259250271. Planner Matzke introduced the request to consider an approval of a Preliminary Plat and Planned Unit Development (PUD) Plan to be known as Trillium Cove. The subject site is located south of County Highway 42, west of Ferndale Avenue, and north of Lower Prior Lake. He explained the history, current circumstances, issues, alternatives and recommended a motion. He presented a location map, development plans dated march 23, 2017, applicant narrative dated march 23, 201, Engineering/Public Works Department memorandum dated April 21, 2017 and Community and Economic Development Department memorandum dated April 24, 2017. Engineer Poppler explained the planning plans; stating the site has a lot of topography which makes this a challenging site. He commented on the wetland, storm water and explained where the flow of water would go. He explained the utility plan connections; stating the entirety of completion of Rolling Oaks is in the decision stage. He commented on being in discussions with the neighborhood. He explained the best approach if this doesn’t go forward would be to still bring the sewer and water down Rolling Oaks to connect to this development limiting redundant pipe. He explained the Row Way connections. He iterated the question of a City project should occur with Rolling Oaks or we allow the pipes to be built underneath Rolling Oaks and wait for a later date to complete Rolling Oaks. He stated a meeting date to meet with the neighbors. 2 Planner Mazke highlighted a few more things; landscape plan and tree replacement. He commented on the conceptual home plan examples; single family homes that are multi-level, single level living, and townhomes. He iterated that this was a PUD, (Planned Unit Development) and explained the difference from between a PUD and a Preliminary Plat. He commented on the preservation of the wetland and parkland, trail, public park, sidewalk connections, innovated site design, increased safety views, mixed housing options; HOA, installation of sewer and water being developer responsibility and connection of Carriage Hills Parkway. He said the PUD benefits are weighed against some of the criteria; offer flexible approach, create a sense of place, increase mentality, transportation options, options for life -cycle housing, enhancing some of the public open space opportunities, preserving and enhancing some of the characteristics of sensitive and environmental areas and they offer some high quality compatible designs. He stated they met with the developer numerous times on this project in the last few months ever since they designed their conceptual plan for the site; they continue to make modifications to City Staff comments and he said the developers have held a neighborhood meeting. Commission Comments/Questions: Fleming said he noted the one neighborhood meeting with another meeting that will be held next week. He asked if that utility topic will be the first meeting between Staff and the residents. Engineer Poppler replied this meeting is just for Rolling Oaks, not for any of the other utility connections. He commented on the two prior meetings for Rolling Oaks and stated there will have a third to talk more about what should be done in terms of total improvements to Rolling Oaks or not. Kallberg questioned the reduced setbacks of the building; compensation for the fact that the units per acre are affected by the large wetland and the wetland area is being included in the calculation to get the number of dwelling units being in the low-density area range with the smaller setbacks. Planner Matzke said yes, he is correct; and explained the open space areas, wetlands, storm water ponds and general parks open space preservation. He commented on one of the modifications that is requested. Kallberg said there has been a lot of controversy about Rolling Oaks and potential costs to property owners due to their large lots and asked what will be the impact of connection along Rolling Oaks and County Road 42 on future costs. Engineer Poppler replied the improvements proposed by the developer to bring the utilities down a portion of Rolling Oaks reduces the amount that they would have to front if we did a City project at some point. Fleming questioned how much the reduction would be. Engineer Poppler explained what the savings was three to four years ago. Tieman asked about phasing. He said he knew they were doing the overall grading plan to start; however, Carriage Hills Parkway being part of phase two of the project and connected. Engineer Poppler explained their phasing and grading and the lack of connections and the utilities; stating they are proposing to grade the entire site as one and the street and utility installation for the future phases later. Petersen explained why the Commissioners don’t have a lot of questions. Ringstad asked the difference between a high-quality wetland versus regular quality wetland. Engineer Poppler explained the differences stating it has a unique vegetation. Planner Matzke added as preservation it could offer credit savings as well for the saving of a wetland. He explained how they rate wetlands; on quality basis, based on the credit of replacement. He said this one is one of the more unique and quality wetlands that we have in town. Ringstad questioned the improvements on Rolling Oaks; meeting next week, the cost savings, improvements coming down Rolling Oaks and what is the process for the timing and further improvements on the remaining. He asked if this goes to City Council on a later date? Engineer Poppler explained the process of working in conjunction with the developer back in 2014. He said when the developer stopped working on that project, the City stopped working on the City part of the project per the City Councils request until a development project got further along. He commented on timing. 3 Applicant: Developer Paul Heuer, (Pulte Homes 7500 Office Ridge Circle, Eden Prairie, MN). He introduced his team and commented on the need to develop these two properties, the timeframe it has taken, hopefulness in finding a way to make this work and the times that they have met with Staff. He said he was not giving a presentation tonight, due to previous presentations; however, would like to give a verbal update. He presented a video, gave a verbal update regarding the concept plan; stating it didn’t change at all. He explained his background of building neighborhoods and said he feels especially proud of this one. Fleming questioned the fifty-nine engineering comments and fifteen comments for a total of seventy-four significant comments pertaining to grading, hydrology and wetland so based on your ability to address comments and conversations with Staff and asked did you feel like the remaining seventy-four can be addressed timely. Developer Heuer yes. Ringstad asked for prices on the three different products that he has. Developer Heuer gave the amounts for the single-family homes, single level, and the ROW homes. MOTION BY TIEMAN, SECONDED BY KALLBERG TO OPEN THE PUBLIC HEARING ON 4A AT 6:37 P.M. VOTE: Ayes by Fleming, Tieman, Petersen, Kallberg and Ringstad. The Motion carried. Public Comment: Lyn Spieker, (14226 Ash Circle NE) She read a letter explaining her time in Prior Lake in the North Shore Oaks Neighborhood. She commented on the informational meeting, meeting with Staff and shared concerns of traffic, lights, tree inventory, storm water runoff, parks, Sandpoint Beach and boats. She asked if a traffic study has been conducted, has the city considered the impact of the four hundred and sixty-eight new dwellings in the three new developments on Sandpoint Beach, additional monies be allocated to maintain and improve the infrastructure at Sandpoint and Prior Lake Boat Access and has this impact been under consideration and if so, how will the City and Minnesota DNR work together to alleviate it. Tim Connors, (14113 Ash Circle NE) He asked if the narrow Ferndale road would be widened, He questioned the time frame of each phase. Fleming said that after the public hearing the staff and applicant will answer all the questions. Pat Simpkins, (5266 Carriage Hill Road NE) He explained his location and shared concerns the Lot dimensions and property values with lower priced homes adjacent to their property. Gordon Erickson, (14071 Rolling Oaks Circle, NE) He commented on the meetings being unofficial, the residents having three options, being charged like a developer, petitioning, no good solutions for them, being backed into a corner, the City Code, developer bringing the road up to City standards, developer loop holes, Outlots F and G development, opportunities to finish off Rolling Oaks, expensive tab and the difference between 2013/2014 and now, who will benefit from the infrastructure going down Rolling Oaks, the difference in their ten properties and how many are going to hook up. He mentioned a statement regarding non-abutting properties and their benefits/charges. He talked of raw deals for the neighborhood with no benefit to the neighborhood. He presented and read off a signed petition from the neighbors and would like the developers to bring the roadway up to city standards. He questioned why am I as a resident required to bring the roadway up to the standard when the developer doesn’t have to. Kurt Stone (14111 Rolling Oaks Circle) He agreed with the prior speaker and neighbor, Mr. Erickson. He said he talked with Gordy and has been to the meeting. He said t he last meeting left him angry. He explained the location of his property and where the sewer and water would go through. He commented on stubs on the sewer, NBCA fees, physical hook up prices, additional fees, unsure of what fees are for unless he was a developer and he is not; he is a homeowner, interest in Rolling Oaks Circle, being railroaded and intimidated three years ago and kicking the can down the road. He talked of the City looking at improving the infrastructure of Prior Lake and help with some of the costs. He said this is a lot of money and asked what can they do. 4 Joe Zieska, (5316 Hampton Street) He commented on Ferndale and County Road 42 not having concrete curb and gutter and would like to see that be a condition of the developer, public safety, access to neighborhood, width of Ferndale, phasing of this development, long cul-de-sac, one in and out, phase two happening in a timely manner and setting a condition of part of phase. He asked how the width of Ferndale compares to the city standard minimum street width, the maximum length on a cul-de-sac, what happens if the economy goes bad and phase two never happens, Fleming said he has the same question regarding the economy; he said I think everyone knows that we are due for a market correction; the question is will it be the third quarter of 2017 or the first quarter of 2018, but it is coming and that is a relevant point. Developer Heuer asked for help from Ryan on the first question regarding a concern of storm water and flooding and said he believe the question was; what in regards to the existing pond in North Arm park. He said they have asked the same questions as they don’t want to flood anyone. He said he asked Ryan numerous time to make sure that things are no worse. Developers Engineer Ryan Bloom, (7699 Anagram Drive, Eden Prairie). He explained working with storm water management with the ponds for the site and offsite ponds as well; making them existing conditions better. He commented on working with City Staff for getting the precise amount of water without discharging any pollutants, water is treated, total runoff and infiltration is all within the City standards. Developer Heuer said the next question was about timing of the phasing; He explained phasing, phasing of construction, regional transportation improvements, primary collector street, condition of approval in phase two, separate projects, development project and public improvement process, State Statue 429, and different timelines. He presented a graphic and said in what happened during the timeframe of 2013/2014. He mentioned his approach with the city this time, different options, different routes for sanitary sewer and water, where the sanitary sewer is currently, neighborhood meetings, asking the neighbors preferences of location of sanitary sewer and the response, watermain with two options and best benefits to the neighborhood. He said they thought they were doing what the neighborhood preferred. He commented on the benefit from the sewer and water and the limit on what they can do as a developer too, as them building the public road is not right. Fleming mentioned one more question that either Mr. Heuer or Staff could answer regarding traffic studies. Developer Heuer said in studying the Scott County transportation plans they have been building out county road 42 to the ultimate design so when cities design their trunk sewer system and their trunk water system and when the County designs their trunk transportation system, they don’t design it based on current traffic they look at the projections they look at every property is zoned how much traff ic each of those properties are going to generate and they design their transportation network based on those ultimate scenarios. This is a vacant piece of property, yes, but it was planned to be developed and the County Road 42 corridor was designed to handle this traffic, ultimately we are required as part of this work to build a new intersection at Meadowlawn Trail and County Road 42 which is intended to take the traffic for this whole region and addition we are required to shut down the intersection of Rolling Oaks Circle and County Road 42 to make it right in and right out, that doesn’t mean that the residents from our neighborhood are going to go through Rolling Oaks Circle, it is really the opposite as if anyone wants to take a left it will bring all the traffic from the two neighborhoods east and west of our neighborhood through our neighborhood to get to the intersection that may or may not have a signal at Meadowlawn Trail and County Road 42. So he thinks these facts are important to keep in mind in terms of the design of the trunk systems, the fact that these are two separate projects and the fact that we been choosing to go down Rolling Oaks Circle because we thought that is what we heard from you folks that this is what you wanted us to do. Engineer Poppler said Mr. Heuer said it well; the transportation system along County Road 42 has been planned for this traffic in this development, we have planned through our comprehensive plan for the connection of Carriage Hills, we planned for the north/south collector roadway to this development and we see the traffic from this new neighborhood utilizing these larger collector systems instead of vice versa where they would be using Rolling Oaks or Ferndale primarily; it would be the opposite, the people would be going to the full access off of 42. 5 Fleming said just to underscore the reality of the two separate processes, is accurate. The public improvement process is not under consideration tonight, the fidelity of that is/or the legality of the fairness of that, with that said all five of us are always interested in hearing about implications of what may occur later and that does give us insight as to how we deliberate on the items before us and what direction or suggestions we might get to staff as projects are moving forward. He would like to take a view on this the two processes are separate but hearing from neighbors and residents and understanding what those intersections of concerns are, do help us make good decisions. Jeffrey Boller, (5311 Carriage Hill Road NE) He asked where Carriage Hills, where they are proposing to put through connects to Carriage Hills Road what kind of intersection is that going to be and how would speed be controlled through the neighborhood that I live in. Developer Heuer explained the properties are narrow and said there is not a lot of flexibility of connecting A and B; the east and west side so we are connecting it with a straight line and recognize that traffic speeds may be a problem once the last connection is made so we proposed a mini roundabout that will calm traffic down. Gordon Erickson, (14071 Rolling Oaks Circle, NE) He said Mr. Heuer is right; two separate projects, forget the public improvement process to 429 and concentrate on this one right here. The residents of Rolling Oaks Circle will wake up at 7am to 7pm listening to heavy equipment tearing up the road putting it back in and we gain zero benefit, we don’t even have a reasonable opportunity to hook at a reasonable cost because of the way the city is approaching this. Some input the city is writing its own destiny on this there is two thing the city has wanted forever; Carriage Hills Parkway since the 80’s, the Boldger and the Griffith family have stopped it at least three times as it was not time to develop. The City wants Rolli ng Oaks off gravel. All the city has to do is ignore the catch 22 the loop hole in the system and say this is all legal and legit and what do we get… we get carriage hills right now and rolling oaks get sent to the sidewalk and a year or two later they get rolling oaks off the 2 percent gravel road its brilliant if you’re just a schemer. Bob Scheeler, (14254 Ash Circle NE) He said he lives on the dead end of Ferndale Avenue. He said his family moved into this community when his kids where in diapers; today his grandkids are in diapers and growing up. I have been going through this my whole life and I don’t have any interest in going any farther, struggling to fight what has been proposed decade after decade. Someone please come and buy my property; he is sick and fed up and ready to move on. And for the poor people on Rolling Oaks, my heart is broken for them, expected to pay hideous amounts that they cannot afford. You brought it up a million dollars to complete that little tiny section almost a million bucks. I would encourage the city for many years because this is prime pristine golden wetlands. If the city wanted to do a beautiful favor for future generations, buy this property and turn it into a pristine park where prior lake will become a destination for everyone in the metro area and not develop it. And again, who wants to buy my property. I have had it. Jim Speaker, (14226 Ash Circle NE) He said he is still wondering what is happening to the pond that is at the end of Ferndale. He said he understands that water gets treated, but he noticed all the trees are marked around this pond which is the park. Are they destined to come out due to the water going up or what is going to happen? He said he understands that it will be treated but what is the impact to the park. Developer Heuer said the level that the pond will bounce to under a one-hundred-year storm will be like what it is now. He asked his engineer; higher, lower or back to back? Developers Engineer Ryan Bloom replied, back to back one hundred year storms and said we are going to be lower than what is there now. Developer Heuer said it sounds crazy; the reason is because the large pristine wetland requires a certain amount of surface water to get to it to remain hydrated, so we had to have a balancing act but in this case the correct ended up being best for both cases. We have more water going into the wetland which keeps it hydrated and we have less water going to the existing pond in the park; therefore, back to back one hundred year storms the elevation of the water is lower than it is now. Sounds crazy but that is how the actual engineering is done in this case. Developers Engineer Ryan Bloom said they did inventory the trees, even along that wetland but none of the trees that were inventoried off of our property counted for the calculation and when we are out 6 there inventorying trees we don’t know exactly where the property line is until we get back into the office, but all the trees were marked, but doesn’t signify anything. Developer Heuer said it is part of the project, we have some land up against the existing park, somewhat step and heavily wooded and we could preserve a chunk of trees on our development and to give that chunk of land to the city to basically expand that park. Tim Connors, (14113 Ash Circle NE) He said his question wasn’t answered regarding the road not being answered; what is your plans for Ferndale and if you widen it, he is not paying for it. It runs right parallel to my property and road is not made to carry heavy traffic and that will be a heavy traffic road. Developer Heuer asked for a graphic from Planner Matzke and said he was unsure of what the width of Ferndale is. It looks like a typical residential street that is paved and is connected to other typical residential streets that are paved. The major roads in this area are not Ferndale, it is Meadowlawn Trail going down the central part of the site, its Carriage Hills Parkway and County Road 42. The traffic once this development is built is going to change, often time there is fear of traffic from the new development going elsewhere; and as he referred earlier because of the closing of the Ferndale in the Rolling Oaks Circle intersections to be right out and right in only it changes everything. He said you will see some traffic going up Ferndale from our development, for those people that are going to be taking a right turn and because you cannot take a left turn anymore you will be driving down Ferndale and connecting into our development as well. He said everything about the traffic in that area is going to change but it is all going to be better overall with Carriage Hills Parkway connected and with the centralized intersection and Meadowlawn going up to County Road 42. But Ferndale is intended to be a local residential street and it is like the streets we are connecting to; they are all local similar streets. Tim Connors asked if it would ease the traffic having two ties into Ferndale, because right now there is sixteen homes in the neighborhood and everyone knows everyone, so would there be less traffic. Developer Heuer said he could not claim that there would be less traffic; he said what he was trying to say is the traffic patterns will change because there are so many connection points there will be difference. MOTION BY RINGSTAD, SECONDED BY PETERSEN TO CLOSE THE PUBLIC HEARING ON 4A AT 7:18 P.M. VOTE: Ayes by Fleming, Tieman, Petersen, Kallberg and Ringstad. The Motion carried. Commission Comments/Questions: Kallberg said this is a difficult decision to make; he said he has been in a similar situation years ago in Spring Lake with sewer and water down the mile-long dead end street. He said there were sixty homes to share that, not ten. He said it wasn’t quiet as significant. He said one of the things that he would like to mention is the assessments for infrastructure and improvement cannot exceed the increased value of your property and results from that improvement. He asked if that is still correct. Engineer Poppler said yes that is still correct. Kallberg said I know one person on the street that I lived on when the project was completed asked when he got his money; well not until you sell. He said the developer had shown us two options for bringing in sewer and water to get that westerly connection to the sewer system from 140th under 42; the watermain connection into the project and he understands that when push comes to shove they are willing to do that and would hope that there is some solution to get sewer and water to Rolling Oaks, but doesn’t know that a serious need as they have large lots, private septic and wells that are apparently are serving them well. He said there will be some future costs to them to maintain that. He said his feelings are that we need to find a solution that will satisfy everybody, the sewer and water projects were in Pr ior Lake system are important, no matter how much land you have, sooner or later something must go to the lake and you are close to the lake. So we encourage sewer and water to some of these older developments but we can’t just put this huge burden on the property owners and he would have to support this project only to the extent that the developer either find a different route in as suggested or find a way to make the residents of Rolling Oaks not suffer beyond their means to get sewer and water through their street. 7 Tieman said as Comissioner Kallberg stated this is a difficult decision, with a lot of elements to this project. He said he thinks the developer has presented a good option in order to develop the plan, the property is pretty unique as described affecting a lot of people on both sides east and west as well as the lake itself on the south side, so all these things need to come into factor and he thinks from everything we seen they have taken these things into account and have done their part for developing this property the proper way. He stated he is in support of this project, he said it is the right thing for this piece of land. He said we need to address the Rolling Oaks group and take them into factor and help them out anyway we can because they are getting the tough end of the deal. Ringstad said one question for Staff regarding all the site work that will be done immediately as relates to the future phasing of the project. He asked in 2009/2011 we seen the housing industry crash; and is there a letter of credit that the City will be asking for posted by the developer to ensure that if phases two and three don’t get built in a timely fashion or what is talked about tonight or in the future that there is some way to protect the undeveloped piece of land to restore it through a letter of credit, posted for security. Engineer Poppler replied tonight is the preliminary plat. There is another step called the final plat where we work out the details on what the first phase is and what security needs to be in place to ensure that things happen. The next phase with the final plat when they are building the roads and utilities would have that discussion on what is fair. Ringstad said trees were talked about; there is a very detailed tree replacement plan; albeit, maybe not perfect for the ones in the audience tonight and like the eighty acres the way it looks. He said the look is going to change, tree replacement plan has helped to mitigate some of the trees that will be taken down for the homes, streets and that type of thing. He said he thinks that Chair Fleming counted seventy-four details yet to be worked through. He stated he does support this project; it appears to be well thought out, our neighbors on Rolling Oaks still have some very legitimate concerns that we all have touch on and he said for everyone in the audience it will be a concern for the council and others going forward also. He would like to hope on going discussions will be fruitful and will continue with the neighborhood. He said there are benefits to the City with respect to this PUD. He said overall he will be supporting moving this forward tonight, but again there is some unfinished business and details that need to be worked through as you get toward the final platting process. Petersen said he concurs with fellow Commissioners; he feels the pain of the Rolling Oaks large assessments as he just went through a large assessment a couple of years ago and it is a painful process, but he said saying no to this project is not going to solve the Rolling Oaks problem. He said turning this area into a park is not the question for us the question before us is; is this a decent plan. He said this is a good plan; it benefits Prior Lake and even though it is painful for some of the people close by, it is unfortunate, but believes it is a well-though out, well-developed plan on a difficult piece of property and he stated he will be in support of it. Fleming said he too will be supporting the PUD; it does squarely meet the nine point threshold in Section 1106 of our zoning ordinance and am also going to be strongly echoing his Commissioners with respect to the issues and comments raised specifically about assessment. The costs and burdens of those so as some of you know of me this is an opportunity for the developer and neighbors and staff to not just have more dialog but to really extend positive regard amongst one another and lets figure out if there is a viable option that keeps the fidelity of everybody’s role and responsibility in place. He said he knows that there are at least three City Council members in the room tonight and they are keenly inter ested in furthering this dialog and coming up with a solution that reflects that we are being good stewards of our resources and that we are honoring all the concerns and voices that are shared with us tonight. MOTION BY PETERSEN, SECONDED BY RINGSTAD TO RECOMMEND APPROVAL OF THE PRELIMINARY PLAT AND THE PLANNED UNIT DEVELOPMENT PLANNED FOR TRILLIUM COVE SUBJECT TO THE LIST OF CONDITIONS OR OTHERS THAT MAYBE ADDED OR MODIFIED BY THE COMMISSION INCLUDING BUT NOT LIMITED TO CURB AND GUTTER BEING INTERGRATED INTO THE PLAN AND NARRATIVE AT 7:29 P.M.

Show construction limits in all areas (including areas adjacent to tree preservation areas). Silt fence will also be required in these areas. 7. Proposed grading beyond property lines will require easement/agreement or revise grades to stay within project area. 8. Provide easements for all storm sewer pipes, structures and drainage swales located within common lots. 9. Please review roadway grades at property lines to assure proper elevations at adjacent properties 10. The minimum allowed slope of swales is 2%. Several swales have portions that are less than 2%. Please revise accordingly. 11. Show driveway slopes. Driveway slopes shall not exceed 10%. 12. A minimum of 10 feet beyond the house should have a slope less than 10:1. 13. Revise backyard drainage and utility easements to include swales in the following areas: Block 4 Lots 14, 15, 16, 17; Block 3 Lots 1, 2, 3. 14.

Show emergency overflows for all for wetlands specifically W3. Please show 100-yr back to back storms high water level since this is a landlocked basin. Utilities 1. A detail review will take place once final plat (plan and profile) has been submitted. Below are general comments regarding the utility plans that were submitted with the preliminary plat. 2. Easements over the utilities will need to be in place throughout the Townhouse Development area. It is our understanding that the streets will be private in this area. 3. Add manholes to the storm line draining to Outlot E infiltration basin. 4. FES-92 should be extended down to the NWL of Pond 2PTP. 5. Add flared end section to Outlot E outlet pipe. 6.

Please utilize PVC for watermain for the project. 13. Please add additional manholes for the sanitary sewer on Rolling Oaks to keep the sanitary sewer in the center of the right of way. Streets 1. A detail review will take place once final plat (plan and profile) has been submitted. Below are general comments regard the street plans that were submitted with the preliminary plat. 2. Provide turning template for roundabout. 3. Sidewalks that are on private property shall have easements over them. 4. The high point on Hampton St. NE at station 17 seems to be un-necessary. Please review and remove. 5. Cul-de-sacs and parkway design do not meet City standards. Due to future maintenance of these areas, the City would prefer not having these areas. A homeowners association can disband or be ineffective in performing maintenance over the long term. 6. Provide street and storm sewer sheets. 7. Provide details of connections to existing streets. 8. Provide signage and striping plan. 9. Final plat drawings should show ped crossing locations. 10. Please show how Ash Circle squares up with the curvature of Ferndale. Intersection detail will be needed. Hydrology and Stormwater Management 1. A detail review will take place once final plat (plan and profile) has been submitted. Below are general comments regard the street plans that were submitted with the preliminary plat. 2. The City standard for rate control is based on NOAA Atlas 14 precipitation data along with the MSE3 rainfall distribution. The submitted HydroCAD calculations use the MSE3 distribution but not the Atlas 14 data. Areas draining to the Prior Lake Outlet Channel (PLOC) may utilize the old rainfall amounts (2.8”, 4.2”, 6.0”) and distribution (NRCS Type II). Other areas must be calculated using the newer data. 3. Considering the topography it can be expected that multiple ponds are needed, but can some of these ponding areas be combined. Certain ponding areas are so small they may not function well. Regional ponding is always more desirable. 4. Please review the low floor elevations and EOF for lots 1-5 block 7. 5. Assure safety bench is provided for all ponding facilities. 6. The invert elevations of pond inlet flared end sections shall match the OE of the pond. Submerged outlets will only be allowed at the discretion of the City. 7. The EOF of a pond should be at least 1 foot higher than the HWL. The top of dike elevation should be at least 2 feet higher than the HWL. 8. Show or define access routes for maintenance purposes to all stormwater infrastructure and ponding areas (maximum of 8% grade, maximum of 2% cross slope, and minimum of 10' wide). Drainage and utility easements shall be dedicated at the time of final platting to provide this access. 9. Pond outlets shall provide floatable debris skimming for the 10-year, 24-hour rainfall event (NRCS MSE3 rainfall distribution). A manhole with a baffle wall with orifice or notch is recommended to control rate. Outlet rate control manholes shall have a top mitered to conform to fill. A 66" minimum diameter is required to provide access to both sides of the weir wall. Please provide a detail for proposed pond outlet structures. SWPPP 1. A detail review will take place once final plat (plan and profile) has been submitted. Below are general comments regard the street plans that were submitted with the preliminary plat. 2. A SWPPP that meets the requirements of the NPDES Construction Stormwater Permit must be prepared for all construction activity that results in land disturbance of equal to or greater than 1 acre. The SWPPP must be reviewed and approved by the City before an Excavating and Grading Permit is issued. All provisions of the NPDES Construction Stormwater Permit & SWPPP must be adhered to for the duration of the City grading permit. Wetlands 1. The City must review and approve the Wetland Permits Application submitted for this project on 4/14/2017. This submittal is still under review. Any drainage, fill, excavation or other alteration of a public waters or wetlands is regulated by the Wetland Conservation Act (WCA), State Statutes 103G.245 and regulations adopted hereunder. The City is the Local Governing Unit (LGU) under these rules. 2. Wetland 1 is one of the highest quality wetlands remaining within the City. It is considered “highly susceptible” to stormwater impacts per MnRAM. The project, as proposed, would have significant impacts on this wetland by changing its watershed and reducing the volume of water available. The plant community in this wetland relies on consistent hydrology. Please route additional runoff to the wetland to maintain its hydrology. The current proposal reduces runoff volume to the wetland for the 2-, 10-, and 100-year rainfall events by 29%, 34%, and 37%, respectively. 3. Buffer strips shall be identified within each parcel by permanent monuments. A monument shall be required at each parcel line where it crosses a buffer strip and shall have a maximum spacing of 200 feet along the edge of the buffer strip. An additional monument shall be placed at the midpoint of each lot and/or as necessary to accurately define the edge of the buffer strip (considering curvature). A monument shall consist of a post and a buffer strip sign. The signs shall comply with City Plate #203, Wetland Boundary Signs. The signs shall be installed prior to the issuance of a Building Permit and should be shown on the approved plans. Buffer strip signs must be purchased from the City at a cost shown on the latest fee schedule.
