Birch Street (south). Care should be taken in the design and layout of Street B to minimize the likelihood of cut through traffic from Birch Street to growing commercial areas north of the site. Street A is located consistent with the access spacing proposed in the 35E Alternative Urban Areawide Review (AUAR). Additionally, the following items should be taken into consideration: • Street A & B shall be 32 feet wide. • Other streets will be allowed at 28 feet wide. • Sidewalk shall be installed along one side of Street A. • Street B shall be completed from Street A to Street F and full 60 feet of right of way will need to be provided for that portion of Street B extending north of Street A. • A turn lane off of 20th Avenue will be required subject to review by Anoka County. • A traffic study will be required as part of the development application. Build Out Plan A build out plan (ghost plat) illustrating a proposed future street system and land use (i.e. single family, townhomes, etc.) for adjacent parcels shall be required. Easements A private power line easement exists across the northwestern tip of the development. Drainage and utility easements shall be provided in accordance with the subdivision regulations. Easements will be placed along all property lines, around wetlands and stormwater ponding areas. Storm Water Management The drainage divide cuts the site diagonally. Most of the surface water flows to Clearwater Creek. A small portion flows to Amelia Lake. The concept plans shows several ponding areas throughout the development. A storm water management plan that meets or exceeds the requirements of Rice Creek Watershed District shall be prepared. • It would be beneficial to employ a stormwater treatment -train design that uses BMP's that can reduce volume and filter stormwater throughout the proposed development. • One (1) foot contours are required. • Rear yard drainage swales that exceed more than four lots in length will require a rear yard catch basin. • The wetland delineation that is shown has expired and will need to be updated. • A Rice Creek Watershed District permit will be required. We recommend beginning discussion with the district as soon as possible. 6 •
