Prior Lake, MN 55372-1714 PLANNING REPORT PRESENTER: PUBLIC HEARING: DATE: 5B PUBLIC HEARING TO CONSIDER A REQUEST FOR APPROVAL OF A PLANNED UNIT DEVELOPMENT PRELIMINARY PLAN AND A PRELIMINARY PLAT TO BE KNOWN AS SUMMIT PRESERVE DANETTE MOORE, PLANNING COORDINATOR X YES NO-N/A -- APRIL 23, 2007 AGENDA ITEM: SUBJECT: INTRODUCTION: Cardinal Development has applied for approval of a development to be known as Summit Preserve on the property located at the northeast intersection of CSAH 18 and CSAH 42. The application includes the following requests: . Approval of a Planned Unit Development Preliminary Plan; . Approval of a Preliminary Plat. The proposal calls for a mixed use development consisting of retail, office, restaurant, residential, and park on approximately 55 acres (gross acreage). HISTORY: In late 2005 and 2006 concepts for the CSAH 42 and CSAH 18 site were brought before the Planning Commission and City Council. At that time, the following was discussed: . The general support for a unique concept in this high visibility corridor. . The need for increased tree preservation. . The need to provide balance between preservation and managing responsible growth. . How the site will address recreational needs of the new residential dwellers. . The need for the concept to provide benefits to the City at large that will meet the Planned Unit Development (PUD) criteria. PHYSICAL SITE CHARACTERISTICS: 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: 1:\07 files\07 subdivisions\07 pre1iminary\summit preserve\pc staff report.doc www.cityofpriorlake.com Page 1 Phone 952.447.4230 / Fax 952.447.4245 Total Site Area: The total site consists of approximately 55 gross acres (54.4 net acres). TOPo2raphv: The site has varied topography, with elevations ranging from 1048' MSL at its highest point to 992' MSL at its lowest point. Veeetation: The site is heavily wooded with 2,110 existing trees, equaling 29,031 caliper inches. The site has 73 Heritage Trees (highly desirable species in fair or better condition, which are a minimum of 27dbh in the case of deciduous trees and 24dbh in the case of coniferous trees). Wetlands: The site contains 17,678 sq. ft. of wetlands. The largest wetland is located in the northwest corner of the property (and is not proposed for filling). Access: Access to the site is from CSAH 42, which is classified as an "A" Minor Arterial in the Comprehensive Plan Transportation Plan. The plan proposes two access points onto CSAH 42: a full intersection and a right-in, right-out intersection from a new roadway referred to on the site plan as Summit Preserve Boulevard (which creates a loop that runs through the project). In addition, the site plan is proposing an access off of the existing Royalton Road from the development to the east. 2020 Comprehensive Plan Desienation: This property is designated for Community Retail Shopping, Low Density Residential, and High Density Residential on the 2030 Comprehensive Plan Land Use Map. Zonine: The site is presently zoned A (Agricultural). Shoreland: No portion of this site is within the Shore land District. PROPOSED PLAN Lots: The preliminary plat consists of 70 lots and 1 outlot for 22 townhome units, 43 rowhome units, 100 four-story multifamily units, and 60 three-story multifamily units. The plan also includes a mix of retail, office, restaurants, and parkland uses. Density: Density of the development is based on the net area of the site, which is 54.4 acres. There are a total of 225 units proposed, for an overall density of 4.13 units per acre. The proposed density will not exceed the allowed maximums dictated by the 2030 Comprehensive Plan for this site. Streets: This plan proposes the following roadways: . Summit Preserve Boulevard will be a public roadway and serve as the main collector for the development. This new roadway will provide two access points directly to CSAH 42. The most westerly access point will provide a right-in, right-out access. The easterly access point (directly across from Aspen Way) will provide a full access and future stoplight (when warranted). At the time of final 1:\07 files\07 subdivisions\07 preliminary\summit preserve\pc staffreport.doc Page 2 plat, the developer will be responsible for designing and escrowing funds for the cost of the future stoplight. . Cardinal Way will be a public roadway accessed off Summit Preserve Boulevard and Roya1ton Road. This roadway will provide access to future townhomes and multiple family buildings. Cardinal Way will stub to the northern property boundary and allow for a future extension when the property to the north develops. . Royalton Road extends from Cardinal Way and will provide a connection point to the adjacent Windsor Estates neighborhood. . Summit Path will extend from Summit Preserve Boulevard and stub to the western property boundary and provide a future access when the property to the west develops. For that reason, the developer will need to revise the alignment of Summit Path to show how the road can be extended without impacting the adjacent wetland in the future. The street names of Summit Preserve Boulevard, Summit Path, and Cardinal Way will need to be revised to avoid duplication with existing roadway names within the City. Sidewalks/Trails: The proposed plan provides both interior trails and sidewalks, and provides connections to the City trail system. The City trail system will extend along the western and southern perimeter of the site (along CSAH 42 and CSAH 18). Currently, the trail is shown on the plans as six (6) feet in width, which is inadequate. As previously discussed, the trail will need to maintain eight (8) feet in width and ten (10) feet in width in key access areas (along CSAH 42 for pond and booster station maintenance). In addition, the trail is located in portions of the future CSAH 42 right-of-way (for the purpose of preserving existing trees). In most cases this will not be an issue. However, the developer will need to provide a plan showing how the revised width and possible relocation of these extensions of the trail (when CSAH 42 is expanded) will not impact trees (particularly in two areas immediately to the west of the full access-across from Aspen Avenue). Park: The development proposes to dedicate approximately 20,000 sq. ft. for a tot lot (located adjacent to the northern property boundary) and 3.1 acres for the proposed greenbelt. The grades existing within the greenbelt area would typically not allow it to qualify as dedicated parkland. However, at the time of the concept plan for the site, the Council indicated that the significance of the continuous greenbelt would justify this area as designated parkland with trails. In addition to the greenbelt and tot lot, once the width is revised, the trail corridor along CSAH 18/42 will qualify for parkland dedication. In the portions of the development where contiguous areas of highly desirable trees exist adjacent to a park or trail, park dedication has been proposed. For the sake of saving additional trees, staff believes this is appropriate. Recent design changes (altered grades, future trail locations, pipes, easements) may impact some of these areas and staff is not able to fully determine what areas will qualify for park dedication at this time. In addition, the developer should provide staff with a concept layout demonstrating how the trail through the greenbelt area 1:\07 files\07 subdivisions\07 preliminary\summit preserve\pc staff report.doc Page 3 could extend into the northern property, taking into account to trees and wetlands (when the adjacent property develops), and provide for a future park connection. A portion of the parkland being proposed as dedicated parkland to the City is at the comer of CSAH 18 and CSAH 42. The developer is proposing a "community plaza" area (schematic of plaza is attached). The "community plaza" being proposed for parkland dedication credit appears to be an extension of the retail/restaurant area (i.e.: stairs, extensive retaining walls) and doesn't to meet the standards necessary for parkland dedication credit. If allowed for parkland dedication, the City would be responsible for maintaining this area. In previous PUD cases, the City has not taken areas for parkland credit if they are more closely associated with benefiting the development and not the community at large. The minimum dedication requirement for a development of this size is 10% of the net land area, or approximately 5.4 acres. Recent design changes (altered grades, possible future trail locations, etc) may impact the amount of land area counted as dedicated parkland. While the developer may have 5.4 acres of parkland dedication, meeting the minimum for a standard development, staff is unable to factually determine this at the time of this staff reports creation. Sanitary Sewer/Water Mains/Storm Sewer: The developer is proposing to utilize the reuse of stormwater for irrigation purposes. For that reason, additional details are necessary to confirm that the system being proposes will be adequate in meeting the needs of the site. The irrigation system is the main component of volume control, thus, detail is needed at the preliminary plat stage. Currently, stormwater calculations are incomplete. The most recent Engineering Department memo (attached) dated April 17, 2007 details the most recent stormwater issues related to infiltration feature sizing, hydraulics, and reliability. City staff has been collaborating with the developer's engineer to work through these issues. However, additional information is necessary to conclude this issue. Booster Station: The development will require a booster station. It would appear that that the proposed location does not provide adequate space around the structure, access to the structure, a necessary hard surfaced apron, and will negatively impact an adjacent Heritage Tree (shown as saved). Engineering staff will continue to work with the developer's engineer to locate the booster station in a way that will meet the needs of both the City and the development. The developer may want to consider architectural modifications/upgrades to the exterior of the booster station. Buildine StvleslMaterials: The developer has provided elevation renderings for the various uses within the development (attached) to demonstrate the proposed building styles. The elevations and the narrative provided by the developer show buildings that are often referred to as being "prairie style". The "prairie style" architecture is most often marked by horizontal lines, flat roofs, broad overhanging eaves, and natural materials (stone, wood, etc.). The architectural style being proposed by the developer is a main 1:\07 files\07 subdivisions\07 preliminary\summit preserve\pc staffreport.doc Page 4 thematic element carried throughout the development. The developer has indicated that the buildings will reflect four-sided architecture (similar high quality materials on all sides of the structures). The materials must meet the minimum Class I requirements and design standards as detailed in Section 1107.2200 of the City Code. The developer has provided preliminary examples and draft association documents demonstrating how the development will maintain the proposed architectural style/thematic elements. More detailed documents for each area will be required with final approval of each development phases. Planned Unit Development Criteria: The developer is suggesting the use of the PUD to allow a mixture of uses, private streets and other modifications to the Zoning Ordinance. Section 1106.501 states the required standards for a PUD as follows: Required Standard: The City shall consider a proposed PUD District from the point of view of all standards and purposes of the Comprehensive Land Use Plan to achieve a maximum coordination between the proposed development and the surrounding uses, the conservation of woodland and the protection of health, safety and welfare of the community and residents of the PUD. To these ends, the City Council shall consider the location of the buildings, compatibility, parking areas and other features with respect to the topography of the area and existing natural features such as streams and large trees; the efficiency, adequacy and safety of the proposed layout of internal streets and driveways; the adequacy and location of green areas; the adequacy, location and screening of parking areas; and such other matters as the City Council may find to have a material bearing upon the stated standards and objectives of the Comprehensive Land Use Plan. Section 1106.400 of the Zoning ordinance lists the types of uses and standards allowed under a PUD. The PUD provisions offer maximum flexibility in many areas, including mix of uses, setbacks, lot sizes, building heights, and so on. The developer is requesting modifications to the minimum lot area, setbacks, reduced parking requirements, the development of private streets, and mix of uses. In return, the developer is offering the following: . Additiona11and for future CSAH 42 right-of-way (approximately 37,000 sq. ft.). . The extent is yet to be fully determined (due to evolving design work); however, the developer has indicated that a main component of the PUD will be the preservation of trees in key areas. Currently, staff has concerns related to grading and utility impacts of existing trees shown on the plans as saved. . The developer is indicating that 6.4 acres of the site will be dedicated as parkland. However, once the standard 10% requirement for parkland dedication is considered, the developer is in actuality proposing to dedicate 0.9 additional acres toward the PUD criteria. Nonetheless, it should be noted that a portion of this dedication is for the preservation of trees. If future design changes impact the trees in these areas, their acreage will no longer qualify as dedicated parkland. . Location of a future booster station site. 1:\07 files\07 subdivisions\07 preliminary\summit preserve\pc staff report.doc Page 5 The developer may want to consider offering additional PUD benefits such as cash contributions toward the tot lot play structure or booster station. As with any PUD, while reviewing the merits of the PUD, the Planning Commission must consider the following: . Does the proposed PUD provide balance between preservation and managing responsible growth? . Does the proposed PUD provide benefits to the City at large that will meet the PUD criteria? . Does the PUD foster the vision articulated by the Planning Commission and City Council during the earlier concept discussions for the site (specifically in relation to the CSAH 42 gateway corridor)? The PUD is divided into the following three phases: Phase 1 ~ Retail/Restaurant/Office/Parking: . Office. 92,340 sq. ft. of office and medical office space contained within three-two (2) and three (3) story buildings. . Restaurant. 14,750 sq. ft. of restaurant space within two-single story buildings. . Mix of Retail and Restaurant. 90,234 sq. ft. of retail and restaurant space within six-single story buildings. . Parking. 46 underground parking spaces and 808 exterior surface parking spaces. ~ Residential Units/Parking: . Two-three (3) story multiple family buildings with a total of 60 units with 93 underground parking spaces and 36 exterior surface parking lot spaces. Phase 2 ~ Residential Units: . 22 twinhome units. . 43 rowhome units. . A 20,000 sq. ft. totlot area/park. Phase 3 ~ Residential Units/Parking: . Two- four (4) story multiple family buildings with a tota1100 units (50 units within each building). As well as 130 underground parking spaces (35 within each building) and 72 exterior surface spaces. ~ Offices/Parking: . Three single story office buildings totaling 23,810 sq. ft. 1:\07 files\07 subdivisions\07 preliminary\summit preserve\pc staff report.doc Page 6 . 98 surface parking spaces. Landscapine: Due to the size of the PUD, the specific landscaping requirements will be reviewed at each final stage. However, it should be noted that additional landscaping will be necessary along parking areas adjacent to roadways and trails (i.e.: parking lot adjacent to the trail, west of the pond). Tree Replacement: There are 29,031 caliper inches of existing significant trees on the site. The current plans show impacting 20,850 caliper inches of the existing trees. The developer has been working with staff to make modifications on the site to decrease tree loss. As the plan has evolved, improvements have been made that have assisted in saving many desirable trees (detailed in the attached narrative). However, staff has concerns related to recent design changes (pipes, easements, grades, etc), which appear to negatively impact some of these earlier strides in preserving trees. Due to these recent changes, staff is unable to accurately determine tree replacement requirements and Heritage Tree credit because the viability of some of these areas with clusters of trees still remains unclear. Once the tree replacement requirement is established, the developer will need to provide specific information detailing how this replacement requirement will be met. Parkine: As the development has evolved, the developer has relocated the larger parking areas to the interior of the project, away from the CSAH 18 and CSAH 42 corridor. The relocating of the expansive parking lots is desirable and supported by staff. The developer has also reduced parking in some areas or provided additional underground parking in limited cases. The narrative (attached) provides justification in relation to the proposed number of parking spaces (shared and alternating occupancy of parking spaces in certain areas, industry standards, etc). Staff feels comfortable with the parking situation currently being proposed as part of the PUD. Traffic Impact Report: A traffic impact report was originally generated in December of 2006. The study concluded that CSAH 42 near the site currently operates at or better than Scott County standards and will continue to do so if the following mitigations measures are implemented: . CSAH 42/18: Adjust the timing of existing signal cycle length. . CSAH 42/ Aspen Avenue: -Control the intersection with a traffic signal when justified. -Build the southbound approach with an exclusive right turn lane and a shared left/through lane. - Extend the eastbound to northbound left turn lane. -Construct a 200 foot westbound to northbound right turn lane. . CSAH 42/Proposed right-inlright-out: -Build a 200 foot westbound to northbound right turn lane on CSAH 42 On March 30, 2007, at the request of staff, the developer submitted a traffic study update indicating how the revised site plan would impact the previously concluded traffic study findings. The March update concluded that the proposed intersections and roadway 1:\07 files\07 subdivisions\07 preliminary\summit preserve\pc staff report.doc Page 7 corridors would continue to operate at or better than Scott County standards if the mitigation plan recommended in the original traffic study (above) were implemented. Market Study: The developer provided a market study dated February 16, 2007 (attached). The market study revealed concerns in relation to the residential elements (particularly the for-sale multifamily units). The developer has indicated that the three phases will be built over the course of the next three years and that they are optimistic that at the time of build out, the market will more readily demand the condominium component. Siena2e: The specific signage for each building will be reviewed as part of the final plans for each area of the development. All signage will be required to meet the regulations detailed in Section 1107.400 of the City Code. The current location of the monument signage is within Scott County right-of-way. The County has commented (attached) that an alternate location will be necessary if the signs should need to be moved in the future with the expansion of CSAH 42. It would appear that the shifting of either proposed monument sign out of their current location may impact trees. The developer will need to provide a plan showing where these signs can be located so they will not impact any existing trees in the future. No signage will be allowed within areas receiving parkland dedication. Fees and Assessment: This development will be subject to the standard development fees. ANALYSIS: The site plan has evolved since the applications original submittal as a concept plan. The developer has detailed these evolutions in their narrative (attached). While City staff is optimistic about the positive outcomes created by many of these changes (ie: increasing preservation of trees), recent design changes (shifting of topographic grades, pipe locations, easements, etc) and possible additional changes (relocating the booster station, trails, monument signs) have created uncertainties regarding the viability of some of these trees. Staff recognizes the importance of fully assessing the impacts to all existing trees in order to fully evaluate and give credit to the developer in cases where preservation has been acknowledged as a key component of the PUD. In addition, staff continues to work with the developer to address additional engineering issues detailed in the Apri117, 2007 Engineering Department memo (attached) . STAFF RECOMMENDATION: Based on the need for the developer to address outstanding uncertainties related to the PUD and preliminary plat, staff recommends the public hearing be continued to allow additional time for these issues to be addressed. The developer has provided preliminary examples and draft association documents demonstrating how the development will maintain these architectural standards/thematic 1:\07 files\07 subdivisions\07 pre1iminary\summit preserve\pc staff report.doc Page 8 elements. More detailed documents for each area will be required with final approval of each development phases. ALTERNATIVES: 1. Recommend approval of the PUD Preliminary Plan and the Preliminary Plat subject to the conditions identified by the Planning Commission. In this case, the Planning Commission should provide staff with findings of fact for the basis of their decision. 2. Table this item to a date specific, and provide the developer with direction on the issues that have been discussed. 3. Recommend denial of the request. RECOMMENDATION: The Planning staff recommends Alternative #2. ACTION REQUIRED: A motion and second continuing the public hearing on this item until a specific date. EXHIBITS: 1. Location Map 2.

Moore - Planning Coordinator Cardinal Development Rehder & Associates KKE Architects, Inc. Natina James Monday, April 6, 2007 PUD Narrative From: Date: Subject: PART I: PUD NARRATIVE The Summit Preserve is approximately a 225,000 square-foot upscale, mixed-used development proposal for the northeast corner of the intersection of County Road 42 and County Road 18 in Prior Lake, Minnesota. The mix of use includes specialty retailers, restaurants, medical offices, office, and several types of housing; including three and four level row houses and town homes. The design's theme includes authentic materials and elements such as stone, wood and trelliswork that complement Prior Lake's natural environment and lifestyle. The buildings will be "four-sided architecture", allowing exposure from every vantage point. They will utilize existing and new site amenities such as "heritage trees" and a new feature pond. The main entrance into the site is a tree-lined boulevard that will offer access to the different areas of the development. The corner of County Road 18 and County Road 42 acts as a gateway for the western edge of Prior Lake. A majority of heritage trees on this corner have been preserved to reinforce the .natural" theme of the project. This corner also merges a dedicated park area with a pedestrian plaza for social gatherings and activity. The medical office portions of the development contain Class-A office space and secure underground parking. The use of materials, colors, texture and trellis elements break up the scale of the buildings and are consistent within the entire development. The facades will reflect a natural aesthetic that speaks to the lifestyle of Prior Lake. Compared to developing the property within single-use zoning parameters, developing the 54.82 acres as a PUD adds more value to the community. It also exceeds the community's health, welfare and safety requirements. The design team has met PUD criteria by the following points: · The Summit Preserve proposal creates a more efficient and higher use of land through providing mixed-use opportunities, allowing dedicated open-space and public facilities, and preserving and enhancing the natural amenities of the site. The project is providing approximately 121,000 sf. of office space, 105,000 sf. of retail space, 22 new town homes, 43 new row houses. It also includes approximately 160 multi-family units. · The project provides a .sense-of-place" by identifying and celebrating the boundary of the City of Prior Lake. The project creates opportunities for social gatherings and events outdoors, establishes a formal park area, and utilizes a storm water retention pond as a design feature embraced and accessible by the retail center and pedestrian plazas. minneapolis las vegas irvine pasadena expanding the vision" PUD Narrative KKE 0708.1221.01 Monday, April 2, 2007 Page: 2 · The project increases economic vitality for Prior Lake, and provides investment opportunities by providing a mixed-use platform designed to endure and prosper. The variety of uses within the project creates economic opportunity, stability, and jobs while growing the tax base for the community. · The proposal offers a diversity of housing options; town homes, row houses and multi- family residences to provide housing opportunities for a wide range of age groups and lifestyles. · Summit Preserve passes the "popsicle test" requested by Prior Lake city staff, (Le. a child can go from their home to the store for a popsicle in a relatively safe manor.) The design also includes numerous walking/biking path options, which connect residential areas to dedicated parks, green- pace, and retail/office environments. · The project integrally incorporates 6.44 acres of park space and 7.21 acres P.U.D. open- space. This is approximately 25% of the overall site. The project also provides dedicated parkland on the southwest corner of the site (corner of Cty Rd 18 & 42) and a half-acre tot park on the northeast corner of the site. · The design retains 47.2% of heritage trees overall and 54.8% excluding ROW/Pond/Easement loss. In certain areas, the plan provides retaining walls in order to maintain existing grades that maximize existing tree health and longevity. We have taken care to overlay the trees canopies, specific to staffs request, on the site plan to ensure that the trees we're attempting to save will be viable. · The team has preserved 8,339.5" caliper inches of existing trees. · When planting new trees, care has been made to replace the trees with a species to match those lost in the development. · The Southwest corner, while currently quite open, will be planted to continue the "woodland" character of the site. · The south edge of the property along County Road 42 will be planted to continue the "green boulevard" effect to be consistent with the 2030 Vision and Strategic Plan: "Encourage green belts between developments and major roadways to preserve the natural look of Prior Lake". We have planted and maintained several areas along 42 while still providing visibility to Summit Preserve for Passing Traffic. · Existing wetlands will be utilized as is, or modified to create a retention pond for storm water management. This feature pond, in the main retail development, has been designed to fully manage all storm water on the site and will be used for on-site irrigation. The site, as designed, embraces the pond as a valued amenity and provides numerous plazas and seating opportunities overlooking the water. The pond will contain various levels of water, depending on the water management cycle, but it will remained "filled" at all times, thereby improving the aesthetic qualities of the storm water management system. A water feature in this pond is also being planned. PUD Narrative KKE 0708.1221.01 Monday, April 2, 2007 Page: 3 · The proposal maintains the natural characteristic of trees and topography at the southwest and southeast corners of the site. The southwest corner's natural rolling hills and mature oaks reflect Prior Lake's active and natural setting. The southwest corner will also be planted with several wildflower gardens featuring natural plants, grasses and perennials. A grand stair leading to public plaza with seating will include stonewalls and educational plaques describing the natural wildflower gardens and restoration of the woodland area. The natural plantings not only fit with the Architectural Prairie style of the project, but also helps connect the two "Greenbelts. of the project along 18 & 42. · We have redesigned the site to completely preserve heavily treed hill in the northeast corner of area 1 as identified by staff as "significant in size and valuable in reflecting the PUD criteria of the development." · We have also revised the site plan to save another massing of "high quality hardwood trees. in the southwestern area of Area 2 Gust to the west of the main pond). · The southeast corner maintains a large grouping of trees and smaller scale buildings creating a subtle transition to the residential zoning to the east. · The design of Summit Preserve's buildings utilizes cultured stone piers, building bases and accents. Trellis elements, awning structures, smaller scale fenestrated storefronts, detailed towers and gables all combine to create a prairie style aesthetic suitable for the active community of Prior Lake. This design theme is applied across the proposal to create a consistent and integrated environment throughout the proposal. · The site plan of Summit Preserve is sensitive to surrounding land use, both existing and planned. The main retail components are surrounded by a planted boulevard that transitions to adjacent, less intensive uses. Locating the main retail buildings and pond adjacent to County Road 42, the buildings, plazas and pond become design features, which help to screen the main parking fields from view without blocking the visibility of retailers. The uses are also distributed so that buffers occur between the most intensive areas of use and the least intensive areas of use. The proposal endeavors to surround and distribute public green space throughout the project while preserving existing heritage trees throughout the entire project.

Moore - Planning Coordinator Cardinal Development Rehder & Associates KKE Architects, Inc. Natina James Monday, April 2, 2007 Architectural, Site & Signage Design Guidelines From: Date: Subject: The Summit Preserve is approximately a 225,000 square-foot upscale, mixed-used development proposal for the northeast corner of the intersection of County Road 42 and County Road 18 in Prior Lake, Minnesota. The mix of use includes specialty retailers, restaurants, medical offices, office, and several types of housing; including three and four level row houses and town homes. The design's theme includes authentic materials and elements such as stone, wood and trelliswork that complement Prior Lake's natural environment and lifestyle. The buildings will be "four-sided architecture", allowing exposure from every vantage point. They will utilize existing and new site amenities such as "heritage trees" and a new "pond". The main entrance into the site is a tree-lined boulevard that will offer access to the different areas of the development. The corner of County Road 18 and County Road 42 acts as a gateway for the western edge of Prior Lake. A majority of heritage trees on this corner have been preserved to reinforce the "natural" theme of the project. This corner also merges a dedicated park area with a pedestrian plaza for social gatherings and activity. The medical office portions of the development contain Class-A office space and secure underground parking. The use of materials, colors, texture and trellis elements break up the scale of the buildings and are consistent within the entire development. The facades will reflect a natural aesthetic that speaks to the lifestyle of Prior Lake.

Natina James Monday, April 02, 2007 Parking Ratio Justification From: Date: Subject: Per commentary of city staff dated March 16, 2007, this memo will supplement the development narrative and respond to Item #8 under GENERAL comments from the city. Those comments are as follows: It would appear that the parking shown on the plan is less than what the Code requires for each individual land use. This may be appropriate, however, please provide justification for this within the narrative or on the plan. We have revised the site plan since the March 16th review to increase the parking count. Currently, Site Plan Sheet S-01 dated April 2, 2006 lists six (6) areas of parking "areas. that service six (6) distinct districts within the PUD submission. Each of these "areas. serves a unique grouping of buildings/uses. Some of these groupings do qualify as mixed-use in nature; others qualify as serving a singular use. Area 1 would qualify as a mixed-use zone as parking services two distinct classes of use. Areas 2, 3 & 4 would qualify as single use parking service. Areas 4,5, & 6 are also single use parking service and are dedicated exclusively to residential uses in those areas.

The overall site has a surplus of 2.7% or 37 stalls. The following justifications can be made in allowing the existing parking strategy, as illustrated. 1.) Parking lots for retail spaces in other metro area shopping centers have been trending downward in terms of parking stall ratios per area. This is especially true in smaller, multi- tenant centers and "lifestyle-center" concepts with mixed-use components. Although national big-box retailers and grocery concepts are still demanding 5-stalls/1000 sf. in power centers, local neighborhood multi-tenant retail have been trending closer to 4 and 4.5-stalls/1000 sf. with success. Center Parkin Data Type Size Parking Stalls Lifes Ie 419,437 sf. 1,500 Lifestyle 593,015 sf. 2,500 Mixed-Use Nicolette Plaza (2005) Grocery 114,400 sf. 592 5.17 Mixed-Use Regional Southtown Center (2005) Mall 535,135 sf. 2,110 4.10 H brid Lifest e 398,000 sf. 1,840 4.62 2.) According to "Shared Parking: Second Edition", a publication by the Urban Land Institute (ULI), Community shopping centers of less than 400,000 sf. only require a base-parking ratio of 4.0 stalls/1000 sf. (inclusive of employee stalls) during weekend peak-use. Base parking ratios for Office use during weekday peak-use is suggested to be 3.4-stalls/1 000 sf. (inclusive of visitor stalls). 3.) When analyzing base parking data for off-peak office use and community shopping center use, there are opportunities for shared parking stalls to occur between the uses. Given the effort to connect the "areas" of use with convenient sidewalks and crosswalks, sharing of parking is much more likely to occur. Also, close integration of the retail and office use with the neighboring residential development does allow for additional parking requirements to be absorbed by those living in close walking/biking proximities. 4.) Generally speaking, smaller parking ratios do allow developments to more efficiently integrate parking fields with additional green space and landscaping, less asphalt and more pedestrian and bike friendly amenities. Allowing for stronger integration of alternative forms of access to the center will reduce the need for higher parking ratios. Smaller scaled parking fields also allow opportunities for better storm water mitigation, more friendly human-scaled amenities such as plazas and walkways, and offers a more responsible development patterns supporting smart-growth initiatives and long term planning.

Prior Lake, MN 55372-1714 March 16, 2007 Cardinal Development Group LLC Attention: Kurt Larson 3027 Knollridge Drive Prior Lake, MN 55372 RE: Planning Comments Regarding Summit Preserve Development Dear Kurt: It was helpful to have your consulting staff at the March 15, 2007 Development Review Committee to discuss issues related to the Summit Preserve development. The following comments or changes are in response to staffs review of the Summit Preserve development and our March 15th DRC discussion: TREES: An integral part of the Planned Unit Development relates to the preservation of trees and the thematic element of the Prior Lake natural environment. For that reason, we need to have additional information related to how the trees are impacted. The following is necessary before we can fully reach conclusions as to if the PUD criteria is being met in relation to "Preserving and enhancing desirable site characteristics and open space, and protection of sensitive environmental features including, but not limited to, steep slopes, wetlands, and trees"(Section 1106.200/PUD Findings): 1) The plans do not specify which impacted trees fall within easements for public streets, utilities, and storm water ponding areas. In addition, the plans must provide calculations of estimated tree removal in these easement areas, outside these easement areas, and proposed replacement calculations (outside the easements areas and after the 35% allowed removal, the developer must provide a replacement ratio of % caliper inch per 1 caliper inch removed). 2) Provide specific details in relation to alternatives that have been made to the plan which provide for the preservation of trees (Le.-building locations, grading, roadways, etc that have been altered to accommodate the saving of heritage and significant trees. 1:\07 files\07 subdivisions\07 preliminary\summit preserve\3-16-07 planning comments.doc www.cityofpriorlake.com Page 1 Phone 952.447.4230 / Fax 952.447.4245 3) While staff recognizes the value of the developer incorporating some of the Heritage trees into the plan, it would appear that some of the Heritage trees shown as saved are in fact not viable long term. It is imperative that all trees have no impact within the drip line of the tree. Grading, curbing, concrete, and alike within the drip line will compromise the long term viability of the tree and no PUD or Heritage tree credit will be given. 4) During previous concept discussions the Council expressed support of the preservation of corridors of trees along the boundaries of the project, consistent with the 2030 Vision and Strategic Plan: "Encourage green belts between developments and major roadways to preserve the natural look of Prior Lake". The site has opportunities to accomplish this while still providing visibility to passing traffic. 5) Staff feels additional tree preservation opportunities exist on the proposed site plan. The site has a large number of significant trees that may not be considered Heritage trees, but remain significant in size and valuable in reflecting the PUD criteria of the development. Additional tree saving measures should be considered, (two good opportunities to do this would be in the two "knob" areas that were discussed at the March 15th DRC meeting as well as along CSAH 18 and 42). 6) Detail how the plan will meet the tree replacement required for the site. PARKLAND: 1) Park credit is given for areas that provide for public uses and benefit. Please provide clarification as to the public benefit in relation to Park B? 2) The plaza adjacent to the restaurants does not serve a public purpose and should not be included in the public park credit. 3) The park boundaries are 10' away from the buildings. The buildings should maintain the minimum 20' side or rear yard setback from the park boundary. 4) The proposed parks are irregularly shaped (Park C and G in particular). This will cause maintenance and boundary issues. 5) Revise the plans to reflect a trail in Park G, along CSAH 42 ARCHITECTURAL: 1) Reference in the narrative that all buildings will meet the minimum Class 1 material requirements in Section 1107.2200 of the Code. 2) The narrative or a plan should address wall signage specific to Section 1107.400 of the Zoning Code. 1:\07 files\07 subdivisions\07 preliminary\summit preserve\3-16-07 planning comments.doc Page 2 3) Provide information detailing how the prairie style architecture will be assured for the commercial, office, and restaurant uses. Will there be covenants placed on the properties to enforce the thematic style? 4) Provide elevation renderings of the twin homes, row homes, and four story multi-family buildings. 5) Provide clarification as to how the thematic architectural style will be enforced by the "Architectural Committee" and not allow a situation where interpretation can broadly be made in relation to future buildings. 6) The proposed light fixtures are attractive and appear integral to the prairie style architecture. However, public roadway lights typically are one of three already approved light fixtures. The developer may choose to still use the prairie style lights, however, their cost and long term maintenance will need to be maintained by the Homeowners Association (and reflected in the HOA documents and the Development Contract). GENERAL: 1) Please provide a key clarifying the "1-6 areas" referenced in the supporting material and on the site-plan. 2) Revise the Preliminary Plat to remove the tree inventory and other unnecessary layers. 3) Add setbacks to the plan showing the distance between buildings adjacent to the property boundaries. 4) The market study indicates areas of concern in relation to the residential elements (particularity the for-sale multifamily units). Please provide specifics in relation to how the developer plans to address these concerns. It may be helpful to provide estimated timeframes for the phasing plan. 5) The Traffic Study was done in December, 2006, at the time of a previous concept plan. Since that time, the number of residential units and the square footage of office and retail have changed. For that reason, an addendum should be provided that assures the traffic study findings remain valid. 6) Please provide clarification in relation to inconsistent project acreage areas referenced in various portions of the submittal material (Le.: Sheet 1 states 51.96 acres and Preliminary Plat states 54.82 acres). 7) The required parking for the housing units is two (2) spaces per unit. Please document in writing or on a plan how this requirement is being met. 1:\07 files\07 subdivisions\07 preliminary\summit preserve\3-16-07 planning comments.doc Page 3 8) It would appear that the parking shown on the plan is less than what the Code requires for each individual land use. This may be appropriate, however, please provide justification for this within the narrative or on the plan. 9) Are there any specific types of retail/office/commercial uses planned? Or does underlying C-4 zoning apply? 1 O)Clarify if a neighborhood meeting will be held before the public hearing at the Planning Commission. 11 )Revise the street names of Summit Preserve Boulevard, Summit Path, and Cardinal Way to avoid duplication with existing roadway names within the City of Prior Lake. 12)Respond to comments and revise plans as requested in the Engineering memo dated March 16, 2007 (attached). If you have questions relative to the preliminary plat or preliminary PUD process, please feel free to call me directly at 952-447-9813. Sincerely, Q~ fY\.~ Danette Moore Planning Coordinator cc: DRC Members 1:\07 files\07 subdivisions\07 preliminary\summit preserve\3-16-07 planning comments.doc Page 4 Memorandum DATE: April 17, 2007 TO: Danette Moore, Planning Coordinator FROM: Larry Poppler, Assistant City Engineer CC: Steve Albrecht, Public Works Director/City Engineer RE: Summit Preserve (Preplat Project #07-111, PUD Project #07-112) The Engineering Department has reviewed the revised preliminary plat received April 5, 2007 for the subject project. Key issues are highlighted to try to draw out those issues on the project that have a have a direct bearing on the feasibility of the preliminary plat. The following is a list of comments: Kevlssues 1. Storm water calculations are incomplete. City Staff questions the stormwater pond / infiltration feature sizing, hydraulics and reliability. These issues are addressed in more detail in the "Hydrology" section. Key components of this issue include: pond backflow into County Road 42, capacity of overflow into the County Road 42 system, incomplete modeling of the 100 year storm, inundation of tree preservation areas, how to address the variability of water level, slope characteristics, and pond safety. These issues have a direct bearing on the plat configuration. 2. Since the Developer is proposing the re-use of stormwater for irrigation, additional detail is necessary on the system proposed to be assured that it would be a system that would be approved by the City at Final Plat. Since the irrigation is the main component of volume control, detail is needed at the preliminary plat stage. 3. City Engineering Staff does not agree that many of the trees shown on the plan will be saved. Many trees are shown next to buildings, retaining walls, or paved areas. Please reconcile the utility plans with the tree preservation plans. Many trees are located in proposed utility easements. The corner of 18 and 42 is of particular concern. 4. Provide concept plans for the streets that extend to the north. The concept plans should consider site elevation and topography. The proposed Summit Path appears to head toward a wetland. Provide concept plan for the trail alignment to the north. Superimpose the submitted ghost plat including trail on aerial photography to show the forestation and wetland areas to the north. C:\Documents and Settings\dmoore.PRIORLAKECH\Local Settings\Temporary Internet Files\OLK2f\Preliminary Plat Review 041607 (2l.DOC Plat Issues 1. The parkland at the corner of County Road 18 and County Road 42 should be limited to the area north and west of the stairs and retaining walls. 2. The triangular pointed parkland near Outlot A should not be shown as parkland as utilities will eliminate tree preservation efforts at that location. 3. Plat dimension arrows are not pointing to lines properly. 4. Outlot A should be platted with lot 1 block 6 and should be platted with an easement over the ponding area. Gradina Plan 1. Grading easements will be required for the work outside the property lines on Royalton Road prior to grading permit issuance. 2. Show emergency overflow routes from all low points and show elevation of high point along emergency overflow route, including those for parking lot low points. All emergency overflow routes shall be graded and the easement area sodded prior to building permit issuance. 3. Pond access path for Pond 1 should utilize cable concrete and have a maximum grade of 8% and be a minimum of 10' in width. Pond 2 access should be be 10' in width. Public easement should be part of the access path. 4. Provide erosion control plan and SWPPP. The erosion control measures shall be installed and inspected prior to any site grading. All trees to be saved must be protected by silt fence or construction fencing around the drip line of the tree to protect the root system. This fencing must be installed prior to any grading on the site. The erosion control plan should include temporary and permanent turf restoration, sodding and protecting drainage swales, temporary sediment basins, rock construction entrance, etc. 5. Drainage swale areas should be sodded and immediately protected after grading. Building permits will not be issued prior to sodding of swale. Label these areas on the grading plan. 6. Show contact information of the person responsible for erosion control on the site. 7. Provide note stating that all silt fence must be installed by the contractor and inspected by the City prior to any site work. 8. Provide top and bottom elevations for all retaining walls. Walls exceeding 4 feet in height should be designed by an engineer, include a fence, and must have a building permit. Linetype used for retaining should stay consistent throughout plan to provide ease of identification. 9. Provide proposed contours for parking lots on Lot 1 Blk 5. 10. Proposed grading at Lot 1 Blk 4 seems to create a low point, please revise grades.

The tree preservation plan does not accurately depict the proposed property line and easement configurations. Hvdroloav and Storm Sewer 1. The following comments remained after reviewing the 4/5/07 Stormwater Management Report. Revisions to the Stormwater Management Report came in dated 4/16/07 but were unable to be reviewed thoroughly prior to this memo. This memo does not cover comments on that update. 2. Please make a case for the safety of this pond given that is does not have a safety bench and has a 3:1 slope. Are any other safety measures planned? 3. Currently county storm system is modified by making it function under pressure flow in some water level conditions permission for any such changes will be required. Use of County system for storm outlet will require county approval as well. 4. Modeling of 100 year event at conservatively high pond water level is required. Outlet characteristics must meet requirements of Section 7 of Hydrology Appendix. 5. Reliability of stormwater recycling pond should be explored by processing a wider variety of precipitation years, statistically how often will supplemental water be needed? How often will outflow or overflow occur? 6. Section 4 PWDM - Hydrology Appendix spells out rate and volume criteria. The stormwater management report should include a summary of the volume control requirement and the credit claimed by use of the stormwater recycling pond. 7. PWDM Section 5 details the requirements for drainage alterations and connection of landlocked basins. Stormwater management report should include a discussion of the size and scope of each drainage alteration and landlocked basin connection on site. The recycling pond and outflow characteristics likely meet the requirements, however calculations must be shown. A summary of the questions that need to be answered includes: Is lost storage volume of landlocked connection mitigated? Are any downstream systems burdened by the connections or alterations? Is peak rate in gaining subwatershed held to rate standard? Does PLSLWD approve? 8. Provide easement for storm sewer between Lots 16 & 17 Blk 3. 9. Storm sewer manholes should be added to eliminate angled connections of storm sewer catch basins. These areas include storm sewer connections crossing sidewalks and property lines at sharp angles. In the future if these pipes need to be replaced it will entail additional sidewalk replacement if the current configuration is used. 10. The covenants for the development should include the maintenance plan for the ponding areas. C:\Documents and Settings\dmoore.PRIORLAKECH\Local Settings\Temporary Internet Files\OLK2F\Preliminary Plat Review 041607 (2).DOC Utilitv Plan 1. The booster station is now shown at the corner of County Road 18 and County Road 42. A number of concerns have developed now that the booster station is shown on the plan at this location. The concerns are as follows: a. The Booster Station should be platted as City property or have a utility easement with at least 30 feet surrounding the building for maintenance and operations. b. The booster station location should be shifted to the west and north to provide a concrete landing area for parking a utility vehicle away from the trail. The watermain for the proposed buildings north of the booster station should be achieved east of the booster station. c. The booster station will require a transformer adjacent to the building. d. Since the booster station building will be built into the hill, fencing will be needed to obstruct access to the roof. 2. Provide looping of watermain for watermain located within the parking areas north of the pond to provide sufficient fire suppression. Hydrants should be kept within easements. 3. Utilities are located under the median areas along Summit Preserve Boulevard. It appears that trees are proposed in the median areas on Summit Preserve Boulevard and in other easements. If any trees are located in the median areas, the species must be reviewed as acceptable species above the utilities and near the streets. These species would be shallow root species. The City will not replace any trees or sprinkling systems within the right of way or easements if maintenance activities necessitate their removal. Trees should be eliminated in other easement areas. 4. Manholes must be added for each commercial sanitary sewer service. 5. The landscaping plan should show utilities and grading as a part of the drawing background to facilitate proper placement of replacement trees and landscaping. Streets 1. At final plat, a geometric design plan and traffic signal plan for the eastern Summit Preserve Boulevard full access intersection will be necessary. The left turn lane for Summit Preserve Boulevard onto County Road 42 should be reviewed at that time and possibly extended from County Road 42 to Cardinal Way. 2. The minimum median width should be 6 feet. 3. Street light details submitted do not match those approved by the City of Prior Lake, please coordinate with the City regarding the approved street lights on public roadways. 4. The minimum bituminous trail width is 8 feet. The trail along County Road 42 between Summit Preserve east and County Road 18 should be 10 feet in width to provide an access path to the Booster Station and the Pond access. The 10 foot path should be designed using a minimum of 4" of bituminous. C:\Documents and Settings\dmoore.PRIORLAKECH\Local Settings\Temporary Internet Files\OLK2f\Pre1iminary Plat Review 041607 (2).DOC 5. The trail along County Road 42 should be located 1 foot south of the northern property line unless the trail is meandering to avoid trees. In those cases the trail location should be as close to the trees as possible. 6. The trail location near the eastern Summit Preserve Boulevard entrance should be located just south of the tree preservation area. 7. After reviewing the latest drawings please remove the temporary cul-de-sac at the end of Cardinal Way. 8. Please remove stairs and retaining walls in parkland area and right of way. 9. Remove the crosswalk on Summit Preserve Boulevard at Summit Path. 10. Remove crosswalk on Cardinal Way near lot 17 block 3. 11. Remove the southerly crosswalk at the western Summit Preserve Boulevard. The "pork chop" median at that entrance should also be removed as County Road 42 has a median restricting left turn movements. A "one-way" sign would be located in the County Road 42 median. 12. The circular crosswalks should be straightened. 13. Cul-de-sacs must follow City standards as outlined in the Public Works Design Manual. 14. The parking area east of the western Summit Preserve Boulevard entrance should be moved out of the parkland area and must meet setback requirements from the property line. 15. The parking area east of the eastern Summit Preserve Boulevard entrance must meet setback requirements from the property line. 16. The signage located within the County right of way must have County approval and will be reviewed for sightline issues at the time of final plat. The location of the trail may make the construction of the sign in this area inappropriate. See comment numbers 5 and 6 above.

VERMILLION PUBLIC WORKS DIRECTOR April 13, 2007 Danette Moore City of Prior Lake 16200 Eagle Creek Avenue Prior Lake, MN 55372 RE: Preliminary Plat/PUD Preliminary Comments CSAH 42 and CSAH 18 Dear Danette: We have reviewed the preliminary plat for the property at CSAH 42 and CSAH 18 and offer key comments: . The goal for the right-of-way to be preserved by this development should be minimal disturbance to private property in this area when a future road project is proposed. It appears the development is meeting the spirit of this goal with right-of-way and park dedication. However, there are some issues in the bullets below that will need to be addressed in ensure minimal disturbance. . The proposed park land along CSAH 42 and CSAH 18 shall have drainage and utility easement over the entire park parcels. There should also be a trail easement document over the park land. . The potential for CSAH 42 expansion will require the stormwater calculations/pond to accommodate the future CSAH 42 expansion. The County has reviewed the initial stormwater calculations and there are some concerns that will need to be addressed through discussion with the City and developer. . There are development signs proposed within the County right-of-way. The County may allow the signs by County Permit provided they can be moved in the future at the developer's cost. The County would need to have more information (including a future location identified for the signs to be moved out of the right-of-way with any road expansion) before allowing the signs by permit. . The County is not opposed to having the trail meander into the CSAH 42 ROW at times. However, when CSAH 42 is expanded and relocation of the trail/utilities into the parkland is determined to be needed, the relocation of the trail and utilities into the Park land by the County should be feasible. This does not appear feasible west of Aspen due to a proposed sign and significant trees being called out for preservation that would be in the way of the trail relocation into the parkland. The there are also two staircases that could cause impact to private property and the City booster station along CSAH 42 in the future due to the location. . A future traffic signal need was identified as part of the traffic study at Aspen and CSAH 42. The County considers this signal a development driven signal and funds should be escrowed for the future construction. This will also require a signal design and the proper geometrics at the intersection of CSAH 42 and Aspen to be completed at this time. The signal design may also require improvements to Aspen south of CSAH 42. The current length shown for turn lanes is not adequate to handle the amount of projected traffic nor is there sufficient median width. . The proposed access onto CSAH 42 at Aspen Avenue will require the installation of right and left turn lanes on CSAH 42. The proposed right in/right out will require a right turn lane to be constructed on CSAH 42. . All existing driveway accesses to CSAH 42 and CSAH 18 shall be completely removed from the right-of-way and curb installed. The driveway and pavement/gravel removals and curb installation should be called out on construction plans. . All work within the County right-of-way shall require the appropriate County permits.

"" February 16,2007 Mr. Kurt Larson Cardinal Development Group 1120 East 80th Street, Suite 101 Bloomington, MN 55420 RE: Preliminary Findings for a Proposed Multi-Use Development (Commercial/Multifamily Residential) in Prior Lake, Minnesota Introduction This memorandum summarizes our preliminary findings regarding a proposed multi-use development in Prior Lake, Minnesota. As noted on the site plan, the development is proposed to incorporate a mix of for-sale multifamily housing, commercial office, and retail development. The subject property has a total of approximately 52 acres. The site plan segments the property into six areas. Areas 1 through 3 are located just north of County Road 42 and contain a mix of retail and office space with focus uses such as medical office and office condominiums. Retail components include freestanding outlots in addition to a smaller strip design for Area 2 which contains the majority of the proposed retail development. The following paragraphs address the proposed components of the project including the size of the proposed buildings, a general overview of current market conditions as they relate to each of the components and suggestions regarding refinement of the development concept, project absorption and other marketing considerations. Site Plan The existing site plan offers a strong layout for the various uses. Parking is focused to the interior of the Site, easily accessible to customers but somewhat hidden from the highway. This layout is aesthetically pleasing, but it will be important, especially in the design of the retail space to create interest through exterior designs that face the major thoroughfares (County Road 42 and CSAH 18). Traffic volumes on County Road 42 are substantial and increasing. The sheer volume of traffic on the road will undoubted draw a portion of customers to the site. There is competition in the area including the relatively new Crossroads Center and Savage Marketplace. However, most of the recent development has been developed with big box retailers with limited space remaining for concentrations of smaller users. The subject site offers that opportunity. 615 1st Avenue NE #400, Minneapolis, MN 55413 (612) 338-O<H2 (612) 904-7979 fax www.maxfieldresearch.com Mr. Kurt Larson Cardinal Development Group February 19,2007 Page 2 Without a substantial anchor or anchors to the Site, it may be difficult to attract a sufficient number of small retailers to this location. Many of the national chains have specific criteria regarding their location choices and co-locating adjacent to or within a center that has significant larger retail generators. Currently, however, there are a number of national chains actively looking for locations in the Twin Cities including Trader Joe's and CVS Pharmacy, several that can attract smaller users to co-locate with them. Walking paths, sufficient green space/landscaping and water features enhance the attractiveness of the site for commercial users as well as prospective residents. We recommend that additional landscaping/berming be added to the area between the retail parking area and south part of the buildings in Area 5, those that face the interior road, overlooking the surface parking for the retail center. Increasing the landscaping adjacent to the residential parking area will mitigate the less attractive views from this portion of the site and will increase the value of the proposed housing units. The substantial amount of tree cover between the four-story and three-story buildings will substantially increase the value of these units to prospective buyers. Existing Market Conditions Retail Retail markets in the Twin Cities have remained strong despite downturns in other real estate sectors. New retail developments in growing suburban areas such as Maple Grove, Eden Prairie, Woodbury and Blaine have been highly successful and small chain outlets and major anchors expand their space into these areas. In the vicinity of the subject site, Savage Marketplace and Southbridge Crossing have attracted smaller retailers to fill out around the larger anchor tenants. Rents have remained high and are increasing as consumer sales remain strong. Overall, rents at newer centers in Savage and Shakopee exceed $20.00 per square foot triple net. Lease rates for smaller users are approaching $25.00 per square foot. Vacancies are very low. Of a total of slightly more than $1. 7 million square feet of retail in centers with more than 50,000 square feet each, the overall vacancy rate as of2006 was 1 %, indicating significant pent-up demand for additional retail space. Overall, retail vacancy rates in the Twin Cities Metro Area were only 6.0% as of 2006, indicating a strong and stable market for retail space. New concepts continue to come into this market, with new restaurant concepts at the forefront of the influx. The most popular new restaurant format is "fast-food" casual dining which offers the customer convenience and value. Some examples of this that have recently hit the Twin Cities market include Moe's Southwest Grill, Chin's Asia Fresh, Baja Sol, Noodles & Co. and Chipotle. According to the National Restaurant Association, restaurants in Minnesota are an economic engine of growth, generating a substantial amount of sales and tax revenue for the state. The Association goes on to project that by 2012, the restaurant industry in Minnesota will employ another 31, 100 people. These projections support the recent continuous addition of new restaurant concepts to the Twin Cities, not only franchise operations but also independent restaurants. MAXFIELD RESEARCH INC. Mr. Kurt Larson Cardinal Development Group February 19, 2007 Page 3 According to United Properties Market Outlook, the retail market in the Twin Cities experienced another banner year in 2006. While there are concerns that the slowdown in the housing market could also affect consumer spending and "cornfield" development, most of the experts agree that new development will focus on in-fill and redevelopment as big box users and other niche players penetrate densely populated markets. We continue to see strategy proceeding throughout the Twin Cities as big-box and small users continue to try to leverage popular and growing established markets into additional sales. There is a 100,000 square foot Lowe's anchored center currently under construction in Shakopee in the Dean Lakes subdivision. Additional stores joining this development include Ruby Tuesday, BNC National Bank, Holiday, Goodyear Tire and Slumberland. Best Buy will open an outlet in front ofWal-Mart at Southbridge Crossing. TankenoffDeve10pment is proposing a 250,000 square foot center at the comer of Marystown Road and Highway 169. In relation to the proposed development, we believe there is an opportunity for the project to capture retail concepts that are not yet in this market and to fill out the spectrum of offerings as the market grows in income, age and affluence. Lifestyle considerations will continue to be the driving force among the baby boom generation and convenience and value all presented in an upscale environment will fuel sales. Office According to the most recent market update from the Minneapolis-St. Paul office of Colliers Turley Martin Tucker (CTMT), the office market in the Twin Cities is beginning to move forward again, after several years of stagnant rents and high vacancies. Suburban developments are proposed and there is discussion of at least one new speculative office building in one of the core commercial areas within the next few years. Overall, there was positive absorption of 1.35 million square feet of new office space in the Twin Cities in 2006 and marked the third consecutive year of positive absorption dating from 2004. Landlords were more aggressive in seeking rental rate increases in 2006 than in years past when the market remained soft. Larger space users continued to be the most active while the activity of small and medium-size users slowed. Smaller users are have been less likely to move citing the high cost of relocation as a disincentive to changing office space. As the market tightens however, and as rental rates continue to increase, the gap between the higher cost of space, expansion potential and relocation costs will be mitigated somewhat. Class B and Class C space experienced the greatest amount of absorption in 2006. It is expected that the Twin Cities will continue to bum off excess office space in 2007 and landlords will reduce their dependence on concessions to lease vacant space. Overall, the market for new office space however, remains somewhat speculative. We continue to see good demand from medical users (clinics, physicians, dentists, and other related medical practioners), especially as in fill in growing household suburban areas. Again, caution must be MAXFIELD RESEARCH INe. Mr. Kurt Larson Cardinal Development Group February 19,2007 Page 4 exercised with small user markets which are more prone to looking at the significant costs of relocation. We also see modest demand in the office suites market from start-up entrepreneurs and other established small users that want to move out of their home office into an environment that is more conducive to meeting and receiving clients and has some support services such as fax, copying, receptionist, etc. The office condominium market has slowed somewhat from its initial burst of activity in the early 2000s. Rising interest rates caused users to rethink their strategies. For some small investors however, the office condominium is a convenient way to enter the commercial market through leasing one space versus an entire office building. We still see a market for office condominiums, but from a different vantage point than a few years ago. Residentia1-For-Sale Multifamily The housing market has recently slowed and the most recent year-end home sales statistics verify the perception in the marketplace. Tota12006 listings with the Minneapolis Area Association of Realtors were 47,900, down from 57,280 in 2005, a decrease of9,380 sales or -16.4%. The average price of homes slowed increased only very slightly, from $272,522 to $278,462. Listings of existing homes rose dramatically in 2006 to 108,000, up 9% from the previous record in 2005. The buying and selling frenzy that occurred over the past three years has now virtually stopped and markets are shifting back toward appreciation figures that are in the single digits versus the double digits. Each segment of the housing market has been affected somewhat differently by the slowdown. The suburban condominium market has perhaps faced the greatest struggle of all with many developments experiencing slow sales or slow presa1es. Strong competition from suburban townhome developments and price points that were not competitive with other multifamily products caused buyers to exercise more caution than expected. In addition, the primary market segments for suburban condominiums are empty-nesters and young independent seniors. These groups have a myriad of housing options available to them and condominiums reflect only one of the choices. Buyers today are increasingly trying to parlay the proceeds from their single-family home into at least two and sometimes three separate residences, including a home in the Twin Cities, a home down South and a lakehome up North. Moderately priced condominiums in suburban markets, usually sales of existing units have actually been stronger than new units. Nevertheless, as an increasing number of buyers are opting for more convenient lifestyles, the townhome and condominium markets will rebound and increase. We expect sales oftownhome product to rebound more rapidly in the short-term (over the next 18 months) than the market for condominium product. Nevertheless, the underlying demographics are in place to support additional condominium and townhome development targeted to meet the needs of the aging baby boom generation. We MAXFIELD RESEARCH INC. Mr. Kurt Larson Cardinal Development Group February 19,2007 Page 5 believe that as the single-family home market stabilizes, as excess supply is absorbed and construction is curtailed, that renewed activity will result in the for-sale multifamily market. Most townhome products have seen less slowdown in activity and the year-end sales statistics bear out this trend. In 2006, sales of single-family detached homes comprised only 70% of all home sales while multifamily product rose again to 30% of all units sold. This depicts the fact that more households are choosing multifamily product for a number of reasons, including convenience and affordability. Single-1eve11iving with walk-out lower levels continues to remain very popular with the older mid-age professionals and empty-nesters that want more freedom from home maintenance. Townhome living appeals to the younger household as the price of new single-family homes continues to rise, often beyond the reach of many first-time homebuyers. During our analysis of Scott County's housing submarkets, we noted that the average cost of a new construction home in Prior Lake was just above $400,000. Existing home prices were not far behind at $360,000 in 2006. This price point reduces affordability for many younger buyers. Also, we have noted that today's buyers are having a difficulty in understanding the pricing differentials between townhome product and condominium product. While buyers prefer having underground heated parking and elevators to take them directly to their front door, the additional construction costs associated with these features increase the per square foot price relative to townhome product. In comparing costs and pricing, many buyers are really not comparing "apples to apples." Association fees for condominium units are also usually higher than those for townhome units. This also appeals to price conscious buyers who prefer to minimize these costs. Average per month absorption for townhome developments has ranged between 2 and 5 units per month depending on the product type and price point. Higher priced developments are absorbing at rates at the low end of this spectrum while entry-level developments are usually absorbing at the upper end. Absorption of suburban condominium developments has varied widely, with some developments absorbing at much less than 1 unit per month. Others that have experienced moderate success have absorbed at rates of about 3 to 4 units per month. We note that several suburban projects that experienced success initially with high presales rates, stalled either just after reaching their presa1e quota or just before reaching it. Those that have fmished construction have often experienced significant difficulty in selling out and some have actually lost reservations and/or sales from buyers that became nervous about the developer being able to fulfill commitments. We have found the following characteristics can indicate a higher level of success in marketing condominium units: MAXFIELD RESEARCH INe. Mr. Kurt Larson Cardinal Development Group February 19,2007 Page 6 · Smaller buildings with fewer units per floor reducing long hallways; · Careful targeting of market segments; · Close proximity to retail goods and services; · Pet friendly buildings; · Larger size units and open floor plan designs; Overall, we view the townhome portions of the development will be well-received in the marketplace. We suggest greater caution with the condominium components of the plan, potentially reconfiguring Area 5 or simply waiting a time for the market to catch up. Suggested Phasing and Concept Plans Retail As mentioned previously, retail development has exhibited the strong market dynamics over the past three years. Retail development, particularly in growing suburban areas has continued unabated and new centers have leased rapidly. Restaurant concepts continue to search for prime locations in densely populated and new communities and the location of the proposed development is attractive for these types of uses. The high visibility of the property on County Road 42 will add to its ability to attract users. For the larger center, signage on the buildings that face County Road 42 will be important to increase awareness of the users in the center to those traveling on the highway. We understand that the City has agreed to allow for a higher proportion of signage (including pylon signs in addition to signs on both sides of the buildings) for the retail component of the development because building entrances will be located facing the interior roadway rather than outward toward County Road 42. Although parking oriented to the interior of the site increases the visual appeal of the property from the street, retailers rely heavily on effective signage to major thoroughfares to generate sufficient business to their outlets. Restaurant concepts are most likely to show initial interest in this location given the design of the site and the availability of several outlot parcels. Other neighborhood-oriented retailers will also be attracted to Area 2. As such we recommend that Areas I and 2 be developed first to capture the current strength of the retail market. Office Office development is once again seeing some modest rent increases and gradually declining vacancies, but real estate experts remain cautious. The greatest gains in office absorption occurred in Class B and Class C space and Class B space gained the most. Class B space includes older Class A buildings and new construction small suburban buildings that do not qualify as Class A. Small to mid-size users fueled the demand for Class B space during the period when large users were staying put. MAXFIELD RESEARCH INe. Mr. Kurt Larson Cardinal Development Group February 19,2007 Page 7 Segments of the market that have remained strong through the office downturn were the demand for medical office space, particularly in growing suburban submarkets, office suites, and spaces leased to small and medium size companies that were expanding. The proposed office segments of the plan address the potential demand for medical office space and the need for smaller spaces to accommodate the primary segment of office demand in the suburban market. The plan also shows some office condominium space. We recommend caution regarding the condominium spaces as the market for this type of space has slowed. We do however, see some investors taking on smaller spaces and then leasing out these spaces in the market. The office components exist in Areas I and 3. While office demand is not currently robust, it is on an upswing and is expected to gain momentum over the next 24 months. We believe that it would be appropriate to develop the office components simultaneously with the retail components. Multifamilv Housing Oddly after several years of unabated growth in demand, multifamily housing markets have slowed considerably. Townhome absorption remains moderate and products targeted to empty- nesters such as detached villas and twinhomes are popular. Condominiums, although having experienced some initial success in some suburban submarkets in the Twin Cities, have seen absorption stagnate. Areas 4 through 6 of the proposed plan feature townhomes and condominium buildings. While the townhome products could be marketed simultaneously with the office and retail components, we recommend delaying marketing of the condominium portion of the development by about 18 months until the housing market recovers some momentum. This will enable the empty-nester and senior segments to take advantage of the renewed market momentum to sell their single- family homes and select alternative housing product that will offer them greater lifestyle convemence.
