06.a Narrative - Prelim Plat1 PROJECT NARRATIVE November 15, 2022 Scandia Planning Commission City of Scandia, MN Re: Application for Residential Development ROLLING ACRES 61 The Developer, Doug Schultz with Grandemoore Homes, Inc. along with the property owner, Larry and Kim Reese are pleased to submit this application for preliminary plat review of ROLLING ACRES 61. This narrative is intended to generally describe the project and address specific development topics. Location / Current Use The existing site is a vacant 61.0 acre parcel. It is bordered by residential lots on the east and north sides, Keystone Ave. (CR 50) on the west side and a large, farmed area to the south. The southeast portion of the site is used for agricultural purposes. The remainder of the site is idle to other uses. The site is basically grassland with some intermittent trees located within the northern portion of the site. There are several wetlands located in the low portion of the site. These have been delineated and are shown on the plans. The southwest portion of the site is high ground and void of trees. This is the location of the proposed improvements. The site is currently zoned Rural Residential General (RR-G). This zone is established to provide for principal residential use with large lots. Proposed Zoning The site is proposed to be developed under the Open Space Conservation Planned Unit Development (OS-PUD). This will allow flexibility from the dimensional standards of the RR-G base zoning requirements. Goals for the development are to reserve large areas of land for agricultural use, preserve existing open space to promote natural resources and habitat, preserve existing wetlands, and create a neighborhood which establishes local identity and community interaction. The OS-PUD will reduce the area needed for the development and will preserve open space. Since the site is zoned RR-G and is over 40 acres in size, the OS-PUD district is applied. Specific parameters of the OS-PUD zone are as follows: Density Bonus Additional lots above the base zoning standards is allowed up to a 75% maximum increase. The RR-G zone allows four lots per 40 ac. therefore, the maximum number of lots is seven. Criteria for density bonus for this development are: - Preservation and protection of ecologically sensitive features such as wetlands, native plants and natural habitats – 25% bonus – one additional lot. - Preservation of agricultural land – 25% bonus – one additional lot. 2 - Creating accessible open space – 25% bonus – one additional lot. The total proposed number of lots is seven. Lot Dimensional Standards The OS-PUD zoning allows flexibility to the RR-G lot dimensional standards. RR-G OS-PUD Lot Density 4 7 Lot Size, Min. 2.0 ac 1.5 ac Lot Width, min.

The street will be a rural type of roadway including a bituminous surface and roadside ditches to collect stormwater runoff. The road will be designed per the city’s requirements. The County Highway Dept. has offered several comments: one, that the road connection should be made at 199th Street to align with the existing road. This is not an option since that connection area is a different landowner and purchasing additional property is not probable. Second, that the proposed road connection be made as far south as possible. The location of 198th St. is as far south as we can go. The reasons are: the southwest corner of the site is a low area where stormwater runoff from the site collects today. This low area is landlocked and has no outlet. This low spot drains dry and has no evidence of standing water and did not show any wetland characteristics (as shown on the wetland delineation report). Therefore, this 3 low area needs to be preserved as much as possible to utilize the existing drainage properties. The proposed stormwater pond is built around the low area and because of the landlocked condition it is required to be sized larger than a typical pond. All of these design requirements position 198th St. as far south as possible. Ownership and Management of Open Space Outlot A will be designated as the open space and will be subject to a permanent conservation easement. The current landowner will retain ownership of Outlot A. Stormwater Management Currently the majority of the site drains to the east and towards the north low area. The southwest portion of the site is high and drains towards the low spot in the southwest corner. The proposed road and lot areas are within the southwest drainage area with only a small portion of the house pad areas draining to the north. The proposed improvements will maintain the current drainage pattern. All of the road runoff drains to a treatment pond which provides rate control, volume control and water quality. The treatment pond is located within Outlot B. Since there is no homeowners’ association (HOA) Outlot B will be deeded to the city for the pond maintenance. The treatment pond conforms to the requirements of the Comfort Lake-Forest Lake Watershed District (CLFLWD). A Stormwater Management Plan is included with the submittals and provides a more detailed drainage narrative and hydrology modeling. The plans will be submitted to the CLFLWD for permit review and approval. The project will require an NPDES permit from the MPCA for the grading activities and for stormwater pollution prevention. The NPDES permit will be acquired by the Contractor prior to the start of the site grading. Wetlands There are several small wetlands within the site. The wetlands were delineated by SEH, Inc. The wetlands have been reviewed and approved by the Technical Evaluation Panel (TEP). A copy of the wetland report and approval letter are included in the submittal. All of the wetlands are located in the low area further east and north and are not located within the proposed development project area. No wetland impacts are proposed. Thank you for considering this development project. We look forward to your recommendations and approvals. Doug Schultz, Grandemoore Homes, Inc. Larry & Kim Reese, Owner
