Respectfully submitted, Mary Fogarty DRAFT MINUTES ENVIRONMENTAL BOARD AGENDA ITEM 5A STAFF ORIGINATOR: Marty Asleson, Environmental Coordinator MEETING DATE: September 24, 2014 PROJECT NAME: White Pine Senior Living REQUEST: Rezoning to R -4, High Density Residential, Preliminary Plat Review, Conditional Use Permit for Nursing Home. APPLICANT: Lino Lakes Development, LLC 310 Pinnacle Way, Suite 300 Eau Claire, WI 54071 OWNER: Same as applicant PROPOSED DEVELOPMENT The project site is approximately 2.40 acres, and is located on 77th Street West. This site is guided for mixed use and is currently zoned GB (General Business). There is residential development to the north, Lake Drive to the west, residences to the east, and Market Place Drive and a Kohl's store to the south. The proposed development will consist of an approximately 23,360 square foot, 39 unit senior living facility along with a 28 space parking lot, concrete curb and gutter, driveways, sanitary sewer lateral, water connection to main, storm sewer, and gas, electric and telephone utilities SITE CHARACTERISTICS The site has been previously developed, with only some gravel and an asphalt driveway remaining. Also, 77th Street West runs west to east across the northern perimeter of the site. This roadway is to remain. Topography Currently, the stormwater runoff from the site drains in three directions: Most of the site, including the southern half of 77th Street, drains to a ditch and the runoff is conveyed to the west by an underground pipe system. The southern portion of the site drains south and this runoff is captured by a curb inlet on the service drive behind Kohl's. 1 The western part of the site drains west to an inlet on Lake Drive. There are a couple of minor depressions within the site, but any additional infiltration has been ignored due to the well- draining soils. Surface water Since the site will have over an acre of disturbance, an MPCA permit is required and a SWPPP that meets the guidelines of the issued permit. In addition to the SWPPP plan sheet, the SWPPP must include specific requirements of the MPCA permit. Items include: • Proposed erosion prevention and sediment control BMP's to control the discharge of sediment and/or other pollutants from the site, particularity at the point (s) of intended discharge. • Must provide the knowledgeable person/chain of responsibility information. We need the name of the person that is knowledgeable and experienced in the application of erosion prevention before and during construction. The owner must identify who will have the responsibility for long -term operation and maintenance of the permanent stormwater management system. The owner must include in the SWPPP a chain of responsibility with all operators on the site, or if not known, the title or position of the responsibility of responsible party, to ensure that the SWPPP will be implemented and stay in effect until the construction project is complete, the entire site has undergone Final stabilization and a NOT has been submitted to the MPCA. • The permitees must provide training documentation that the individuals listed as SWPPP overseers are certified by a MPCA approved training method. With that the City would need names of the person or persons involved with SWPPP management, dates of training and the names of instructors of entity providing training, and the content of the training course or workshop including the numbers of hours training, • Location of the SWPPP on site and the location of all required weekly, post - rainfall event inspections and follow -up corrections • The SWPPP must incorporate the requirements (MPCA Stormwater Discharge Design Requirements) including calculations for the project. The submitted SWPPP simply states it will be kept at the construction site. • Site specific quantities must be included for all erosion prevention and sediment control BMPs. • Must include maps of all surface waters and wetlands, and stormponds or basins that can be identified on maps such as a USGA 7 5 minute quadrangle map, the NWI maps or equivalent maps within one mile (aerial radius) from the project 2 boundary that will receive stormwater associated with construction activity during or after construction. • The SWPPP must describe a maintenance plan identifying who will be performing future maintenance of permanent stormwater treatment systems on the site. • The SWPPP must identify if the projects stormwater flows to an impaired water within 1 mile of the site (aerial radius), and whether or not there is USEPA- approved TMDL for pollutants or stressors for the site. The permitee must identify those TMDLs applicable to the to the projects stormwater discharge. Runoff from all proposed impervious surfaces will be collected by downspouts, or drain to one of a series of catch basins in the paved area. Also runoff from open areas will mostly either sheet flow to the pond or be collected by a series of area inlets. The underground pipe system will discharge to the proposed pond generally east to west. Utilities will connect storm water runoff to an existing catch basin on Highway 23 Development standards set forth by the Rice Creek Watershed District require infiltration of the first 1.1 inches of rainfall over the impervious area. The total existing drainage area is approximately 2.40 Acres. There are 27,084 square feet of existing impervious conditions, and 77,627 square feet of existing pervious conditions. The proposed conditions are 44,158 square feet of impervious and 60,553 square feet of pervious conditions. The developer proposes to manage the water quality requirements using a surface pond providing infiltration. The "A" soils on the site are conducive to this type of stormwater management. This pond will infiltrate the required water quality volume (first 1.1 inches of rain over the impervious area) and route storms exceeding this runoff volume through a control structure in the pond. A control elevation will be established at the quality volume for discharges above this amount of runoff. The 1 -year storm precipitation amount is less than the required quality runoff, thus no discharge from the pond is anticipated from this storm event. Soils Soils present on the entire site are Zimmerman fine sands, HSG "A" with an allowable infiltration rate of 0.8 in/hr. This allows runoff to infiltrate well inside the required 72 hour timeframe. Ground water The Groundwater is found at 18.5 to 19.5 feet deep on this site. 3 Land Cover Land -cover consists of a non - vegetated gravel surface with scattered Siberian Elm. There is a row of Red Pine on the east property line. There are 6 White Spruce Trees on the Northern property line. There is an American Linden on the north central part of the site. Rare and Unique Resources There are no unique resources on this site. Wetlands There are no wetlands on the site. Tree Preservation and New Tree Requirements A tree preservation plan is required for the site. Floodplain The property is mapped on FEMA FIRM Panel No. 27001500005B, for the County of Anoka, dated May 17, 1982, and is in Zone "C ", areas of minimal flooding. Well Point There is record of a 271 foot deep well on the site. The developer must verify the existence of this well or record that it was abandoned and properly sealed. If the developer intends to use this well than it should be added to the project submittals and the area around the well protected during construction. If the well does exist and will no longer be used, then the developer must properly seal the well in conformance with procedures and standards set forth by the Minnesota Department of Health. Landscape Plan The landscape plan must show screening on at least 3 sides. Red Pines on the east side are effectively screening the adjacent property. There are new Junipers and Freeman Maples with existing Green ash on the boulevard that is proposed for the south side. The Green ash are about 20 feet tall and are not part of the project but do add to effective screening. 4 RECOMMENDATION Staff recommends changes and additions be made in reference to staff comments and Environmental Board review comments.

ENVIRONMENTAL BOARD AGENDA ITEM 5B STAFF ORIGINATOR: Marty Asleson, Environmental Coordinator MEETING DATE: September 24, 2014 PROJECT NAME: Mattamy Homes /Watermark REQUEST: Concept Plan Review APPLICANT: Mattamy Homes Limited PURPOSE The purpose of the Concept Plan review is to allow the developer to describe the basic intent and general nature of the entire development at an early stage in the process. The concept plan provides an opportunity for the boards and councils to provide informal review and comment on the project's acceptability in relation to the comp plan and development regulations. Comments received would then be incorporated into the development stage plans as the next step. PROPOSED DEVELOPMENT/LANDUSE Watermark is a proposed master planned development to be built on 372 acres. The site is located between County Road 21 and Highway 35E, just north of County Road 14. The development is proposed to consist of 876 Units, made up of attached row townhouses and detached single family homes on various lot sizes. The proposal contains a central neighborhood park, a network of public open spaces, an extensive stormwater management system, Wetland, and wetland mitigation is located in the open space system. Please see Mattamy Homes narrative dated September 8th 2014. The Comprehensive Plan guides this area as mixed use. This designation allows for up to 20% Commercial. Residential land is allowed to have a net density of 4.5 units per acre, with 2/3 of the residential area reserved for low density not exceeding 3.0 units per acre. Watermark has a gross density of 2.5 units per acre. The net density of the site which is calculated by deducting arterial road right -of -way, wetlands, parks and open space, will need to be determined. It appears however, that the proposal falls below the allowable density for the site, and below the density for Hardwood Creek. Hardwood Creek was a 2005 development proposal for this site. 1 SITE DEVELOPMENT DISCUSSION As the Mattamy Homes narrative states, "there are two driving forces that guide the design of this site, stormwater management and project scope /location ". Staff also notes that the 35E Corridor AUAR will also guide design. Probably the greatest hurdle is stormwater management. There are however, numerous focus issues as listed in the AUAR table of contents that must be addressed in discussion and design of the preliminary plat Present day rule requirements are more restrictive than the AUAR recommendations. Stormwater management for this site is complicated with non - pervious soils, and an underlying tile drainage system that empties into a restrictive, piped county ditch system. There are perched water tables, and requirements for mitigating the first 1.1 inches of rain over design impervious soils. The discharge of volume rates under a limited ditch system, and the phosphorous loaded storm water mitigation create challenges. Setting up a stormwater treatment train was previously explored in the Hardwood Creek Project, and is addressed in the AUAR. Creation of infiltration swales, and a system of evapo- transpiration devices may be a part of this train. Soil amendments in proposed greenways and planting trees would further reduce runoff volumes. Watermark should incorporate into their plan narrowing street widths which may help to mitigate water volume issues. We will need cross section drawings for each type of street section that identifies street width, sidewalks, boulevard widths, street tree planting locations, and utility service locations. OPEN SPACE CORRIDORS The City of Lino Lakes Parks, Open Space and Trails Corridors Manual sets up a system of parks adjacent to open space corridors. The Lino Lakes Resources Management Plan (LL RMP) provides for a system of resource management corridors or open space greenways in identified locations to treat stormwater, protect wetlands and provide and area for wetland replacement. The LL RMP is a watershed based resource plan for preliminary planning of the Lino Lakes Comprehensive Plan. High Priority wetlands are set aside in corridors. There are no high priority wetlands in this development area; however, there are protected wetlands, proposed wetland impacts, and new proposed wetlands created in a proposed open space corridor. The corridor is designed mostly on the north side of the proposal Corridor development to the south on the east side of the proposal, and along a proposed sound barrier (berm) should be enhanced to provide a more interesting meandering system on greenway with opportunities for tree plantings, and trail amenities such as benches. If possible, the proposed central park should be adjacent to the corridor and in tune with the Lino lakes Open Space and Trails and corridor plan. Increasing upland 2 areas along these corridors, with the reduction of pond areas might be offset by the reduction of impervious surfaces (street widths for example). FISH, WILDLIFE, ECOLOGICALLY SENSITIVE RESOURCES The corridor development through the proposed Mattamy project will help as a corridor to mitigate potential impacts to ecologically sensitive areas. Implementing Conservation Design Framework of the AUAR is a requirement for this mitigation as well. Conservation design framework includes core and outlier habitat areas, buffering these natural resources, and providing for connectivity. A section on Ecologically Sensitive Resources in the AUAR should be addressed in detail for preliminary plat. HISTORIC PRESERVATION /SENSITIVE RESOURCES The National Heritage Database with the Minnesota Department of Natural Resources should be a part of the AUAR review for this site. Archaeological findings of the AUAR identify at least one site that would require more investigation. Cultural resources include attempting if possible preserving or integrating the historic community rural history. The Hardwood Creek project had a small area on the North and west area set aside to use as community gardens. This opportunity should be evaluated in the open space areas of the Watermark project. LANDSCAPING Greenway corridors should be extensively landscaped with abundant trees and native plantings in all surface water treatment areas. Native plant use is another element that could be used in the stormwater treatment train. The sound barrier berm as well as screening along 21st avenue, and boulevard trees must be adequately addressed with a landscape plan. NOISE A noise analysis must be provided. Appropriate design must be incorporated to meet state acceptable noise levels. A berm is proposed along 35E. CONSTRUCTION STORMWATER MANAGEMENT /SWPPP The Storm Water Pollution Prevention Plan must be written with specific reference to the site. The SWPPP must all aspects of the Construction Stormwater Permit requirements. Required site specific details must be included. WELLS All private wells must be identified on the site. 3 RECOMMENDATION 1. Address the focus issues of the AUAR. 2. Incorporate Conservation Design Framework imposed by the AUAR to mitigate. potential impacts to ecologically sensitive areas. 3. Design Stormwater management plan with a Treatment -Train approach. 4.

Perform a more detailed Cultural evaluation of areas highlighted in the AUAR 8. Investigate the potential for creating a cultural site, that may include space for community gardens on the site. 9. Submit landscape plans for screening the west edge, the open space areas, and the earthen berm. 10. Provide a SWPPP that is site specific and in conformance with the MPCA construction site permit requirements. 11. Investigate and map all private wells, weather operational or abandoned on the site. 12. Provide a street cross - section with detail for utilities, sidewalks, and boulevard trees. ATTACHMENTS 1. Mattamy Homes Narrative dated September 8, 2014 2. Watermark Concept Plan 3. AUAR Table of Contents 4 Background Mattamy Home Limited Minneapolis Division 720I Washington Avenue Sout . Suite 201. Edina, MN 55438 T (952) 898-2100 ������&U�U� ����N��0���U��N�N� Lino Lakes Minnesota September 8, 2014 �������� :xmm�-o��u� CITY OF LINO LAKES Watermark (previously named Ingleside), is a proposed master planned community proposed on 372 acres generally located between County Road 21 and Highway 35E, just north of County Road 14. The neighborhood is proposed to consist of approximately 876 units, made up of attached row townhomes and detached single family homes on various lot sizes at different price points. The proposal contains a central neighborhood park integrated into network of public open spaces, an extensive storm water management system and a variety of different wetland complexes, both natural and created. The concept plan and proposed house plans have been reviewed by the City Council on two previous occasions; first in the context of the overall Lino Lakes market and secondly with a focus on the house plans themselves. Guiding Considerations While there are many considerations to take into account on a proposal of this size, it is necessary understand two factors that drive the design — stormwater management and project Often, streets and blocks are designed to create sub-neighborhoods by limiting streets that cut through sub-neighborhoods (connectivity) and building cul-de-sacs. In this proposal, it is done primarily to create naturally draining rear yard areas, minimize City stormwater facilities, minimize gas line crossings and allow for an extensive drainage/ponding system to meet requirements set forth by the Rice Creek Watershed District. While decreasing the number of homes that can be constructed, the plan allows for many more walkouts and sub-neighborhoods — allowing for higher priced homes and more desirable (to the market) pockets of development. Secondly, this is a large project located on a site with little amenity other than its ease of access. To be successful, for both Mattamy and the City of Lino Lakes, a variety of products must be introduced to address a broad spectrum of buyers while also speeding absorption. Offering a variety of products not only makes it possible to move up the housing chain within the same neighborhood but also gives the development a more diverse look, different architectural styles CHARLOTTE " JACKSONVILLE ~ MINNEAPOLIS ~unmmno ^ PHOENIX ^ SARASOTA ~ TAMPA ^ TUCSON ~ CALGARY ^ EDMONTON ^ OTTAWA ~TORONTO Mattamy Homes Limited Minneapolis Division and a blend of residents at different points in their life. To design a neighborhood this size with two or three different products would create too much "sameness ". Relationship to Comprehensive Plan Land Use. The City's Comprehensive Land Use Plan has a designation of Mixed Use. Within this designation, there was allowed up to be 20% commercial with the residential land allowed to have 4.5 du /net acre with no more than 2/3 of the residential area being 3.0 du /acre or less. Excluding wetlands, Watermark has a net density of 2.5 du /acre. If all the stormwater ponds, parks, open space, screening and wetland (natural and mitigation) areas were removed, a density of 3.75 du /acre is achieved. The proposal falls well below what is allowed under the Comprehensive Plan and significantly below the previous proposed Hardwood Creek. Environment. Contained within the City's Comprehensive Plan is a Resource Management Plan; this was a joint effort between the City and the RCWD. Incorporated into this was a system of trail corridors, wetland corridors, stormwater facilities and neighborhood parks. Watermark incorporates all these concepts into its design. The RCWD is currently considering removing its WMC designation from the site in order to allow greater creativity and flexibility in design of the open space /stormwater /trail corridor concepts; this should allow for Additional open space not designated as buffers or replacement wetlands. At this point in the design of the neighborhood, the details of all these facilities remain to be decided but Mattamy has provided a generous land use framework within which to accomplish the intent of the RMP. Parks. The Comprehensive Plan contemplates a 5 acre neighborhood park integrated into an open space system that will contain trails /sidewalks that go throughout the neighborhood as well as continue north and west as indicated in the Comprehensive Plan. Mattamy has designed its stormwater system to allow for the possibility of a trail corridor being combined with it as it crosses County Road 21 and travels west to the lake. As part of the neighborhood park, Mattamy would like to work with the City to explore the potential of building a small recreational building (built by Mattamy with park fees) within or adjacent to the neighborhood park. This could be used by city residents for meetings, large picnics, or other events. This had once been considered as a private facility however a private recreational building in the proximity of a public park seemed inefficient. The townhouse portion of the community will have a 1/2 acre private park /playground to serve the residents of the townhouse neighborhood. Mattamy Homes Limited Minneapolis Division Open Space. As discussed above, there is approximately 50 acres of park/open space surrounding all the stormwater ponds, existing and created wetlands that is intended to be dedicated to the City. In total, nearly 37% of the site will be stormwater management ponds, parks/open space, or wetlands. Transportation. The City's Comprehensive PIan contains a collector road that runs north/south through the middle of the site connecting County Road 14 and land to the north of Watermark. Rather than divide the entire property with this road, creating breaks in the open space/surface water management plan and park system, the development proposal suggests looping the collector road to the west to line up with 73rd. (Street A). This also eliminates having a significant road run through the neighborhood where the view from the street is the back of houses. Note that even though Street A is a limited access road, we have designed the adjacent uses to be buffered by either water features, open space or deep, landscaped lots. If allowed, this road would have landscaped medians. In place of the full, north/south collector, it is suggested that a minor collector be built. This street would have sidewalks, and a slightly wider Street section if needed. Lots would have access to this Street. Mattamy would like to explore the possibility of having narrower streets and in select locations to slow traffic and add to the open space. Reduced setbacks could also be used to allow more of the yards to be incorporated into the public open space. This would be addressed in the design of the preliminary plat. House Styles/Lot Sizes House plans and lots sizes have been reviewed with the Council previously but will generally be discussed again as part of this narrative. The intent of proposing many different homes and lot sizes is to: 1. Provide different price points. The cost of a developed lot in this project is about $1400/front foot. Foreoch 10' of lot width, we can expect at least a $14.000 difference in price. 2. Provide different floor plans and overall square footages. Many people are chosing smaller, more energy efficient homes. Family sizes are getting smaller, kids are active in many out-of-the-neighborhood activities; the yard is less important (except in the case of the rear yard as we indicated in a previous presentation). Mattamy Home Limited Minneapolis Division S. Help prevent monotony in the development. In addition to va 'ng house facades density and lot size helps create more variety and, in many cases, sub-neighborhood identity. 4. lncrease absorption. NAHB statistics state that for every $1000 you raise the price of a home, you lose 15OObuyers. Offering a long continuum of price ranges capture more of the overall market, increases sales and puts more homes on the tax rolls sooner. A struggling project is bad for both the City and Mattamy. The single family product line will come in 4 different sizes and corresponding lot sizes — 42' wide lot, 55' wide lot, 65' wide lot and 75' wide lot. Home sizes range approximately from 2000 square feet to 3500+ square feet. The 42vand 55~ wide lot will accommodate a 2 car garage; the rest will all accommodate a 3-4 car garage. Interestingly, in a project we recently opened near Lake Minnetonka, the strong majority have been with a 2-car garage. We may be seeing some generational changes in housing preference. All homes with the exception of the 42' wide Iots are proposed to have 25' front yard setbacks, 7.5 side yard setbacks (both) and minimum 25' rear yard setbacks. In keeping with the market analysis, all the lots have been designed to have a 40/ or greater rear yard. At this point we are proposing the same front and rear setback for the 42' wide product but with a 5'sideyard setback. Since all our homes are built "to the side setbacks" (as are most builders), it is interesting to note that the percentage of open space along a block of homes actually decreases as the lot size goes up. What is critical with narrower lots is the design of the facade; we hope that we have illustrated that our designs take this into consideration in past presentations. The plan concentrates the more dense detached units and the townhomes on the south end of the site where commercial uses are more likely to occur, the park-and-ride is located, and existing townhomes are present. Maximum Yield Plan Comparison It is difficult to accurately compare this proposal against the zoning ordinance in that it is guided for mixed use and zoned agricultural. The Comprehensive Plan allows for a net residential density of 4.5 du/acre or 1,575 units; Watermark contains 876 units. With the limiting density requirement that on 2/3 of the site can be no greater than 3.0 du/acre, a maximum yield would have a unit type mix that is 44% detached (varying lot sizes) and 56% attached. Watermark's unit type mix is 81% detached and 19% attached. The proposed net density is 2.5 du/acre excluding Mattamy Homes Limited Minneapolis Division wetlands. Even if all ponds, parks, stormwater ponds, wetlands and proposed open space are excluded, the proposed density is still only 3.75 per acre; well below the 4.5 du /acre threshold. The Comprehensive Plan allows for 70 acres of commercial. As has been discussed with the City Council, the likelihood of this parcel becoming a type of commercial that would be acceptable to the City is remote. 70 acres will allow for four big -box type centers; if this intensity of commercial is interested in this intersection, it will be on any of the other three corners of CR 14 and 35E; these corners have direct access and visibility from County Road 14. For the sake of analyzing yield, even if the 70 acres of commercial were taken out of the density calculation, Watermark is still only 70% of the allowable density. Phasing Trunk sewer and water serve the site from the south. As can be seen from the development plan, the part of the site that offers the highest amenity (parks, open space, wetland complexes) and greatest potential for creating an exciting arrival is in the center of the site. It is Mattamy's intent to build a model center at the center entrance from County Road 21 offering all 4 detached home products. It is anticipated that the central pond will be constructed along with the park and community center (discussed earlier). Ideally, this part of the neighborhood would open in the fall of the year (Phase 1). At the same time, construction would start on the southern end of the project, allowing us to open the more dense part of the project in the Spring or Summer of the following year. Screening from 35E will be accomplished with berming (15') and landscaping and be constructed along with Phase 1 and la. The absorption rate of the various product types will determine exact phasing but the likely scenario is that phasing will fill in the area between the central park and townhouse area, making use of the infrastructure installed to serve the central park area. We expect to complete the project 8 -9 years after sales start, assuming a construction pace of 100 units per year. Summary Watermark is a unique solution to the natural and regulatory challenges that this site presents. Its proximity to transportation and the rest of the metro area, the surrounding open space and recreational areas, quality schools and a broad buyer profile offer a unique locational advantage. At the same time, these very attributes present challenges to site planning, water resource management, and regulatory approvals. Mattamy Homes Limited Minneapolis Division We believe that this plan is a solid framework with which to proceed to preliminary plat. The plan designates the necessary land area with which to address stormwater management, construct the desired recreational corridors and provide connectivity to future planned recreational areas. Based on sound market analysis, our plan responds to the broad range of home buyers looking to reside in Lino Lakes by offering a broad range of housing options and price points. We look forward to advancing the proposal and addressing more details of the design as we prepare for preliminary PUD approvals.
