Dahlstrom Development LLC #02-2789/02>2840 *Stonebay ’ Final Development Plan Review October 18,2002 Page 4 2. - (Sheet C2.3, North Lane Section) The parallel parking along North Lane is in close proximity to a retaining wall with little space for vehicle driver or passengers to exit the vehicle. These areas should be provided with additional width and/or railings to eliminate this potential conflict. - Handicap accessibility - sidewalk cuts are shown at 12:1 slope, could be flatter (20:1 suggested by Case) - need to review in terms of ADA requirements. - The pond ‘overlook ’ across Kelley Parkway from the main entrance is located and sized to accommodate a future bus shelter. Tom Kellogg has provided comments in relation to engineering issues in his letters dated October 1,2002 (Exhibit B-1) and in his comments on the Concept Plan dated May 9,2002. Sheldon Johnson provided his original comments regarding transportation matters in a memo dated August 8,2002. Many of the issues brought up at the Concept Plan stage have been resolved. A number of issues remain to be addressed. These include: Ssw£t: Sanitary sewer capacity south of Highway 12 will be limited until Mn/DOT rebuilds the sewer lines along the New Highway 12 corridor and Orono rebuilds the segment between 12 and the tracks. Since under Duhlstrum’s staging plan the first units needing sewer capacity won ’t come on line until late in 2003, and the sewer reconstructions are planned to happen in 2003, we believe that capacity will not be exceeded. Per Kellogg ’s latest letter, plans should show how the commercial Oullots will be served by sewer. Manhole details need to incorporate Infi-Shield exterior sealing system or equivalent. Water: No remaining design issues. Stonn The stormwater pond outlet under Highway 12 has been revised as requested to align with the downstream ditch w est of the golf dome. A number of requested details have yet to be submitted: 1) Grading plans to shov/ 100-year highwater elevations and proposed emergeney overflow elevations and locations for all ponding areas. 2) 2’ of freeboad must be provided between all basement elevations and pond high water levels. 3) A drainage area map, storm sewer and ponding calculations must be submitted for review. 4) Wetland delineation report must be submitted for review. 5) Need MCWD review and approval of stormwater plan. Sil? Grading- Overall site plan should include an earthworks summary to quantify the proposed cut and fill. Retaining walls over 4' require an engineered design. Erosion control comments by Bonestroo and Associates are included herein as part of Exhibit B-1.
