%�i ii♦ BKPV 4111 June 5, 1997 Ms. Pam Sheldon City of Mounds View 2401 Highway 10 Mounds View,MN 55112 • Dear Pam, • Enclosed are 12 copies of revised and additional plans for MSP's Silver Lake Commons project. Aremte_-jre Survey(with 2 full sized copies) Site Plan Interior Ce=ran Landscape Plan Drainage Plan with calculations Three bedroom floor plan cn dine?!np Four bedroom floor plan The Landscape Plan shows the existing trees that we feel can be saved—these include a grouping of cottonwoods and elm at the site entry and many of the oak and pine trees in the play area. We + + have shown overstory,ornamental and screen plantings on the plan,and have shown areas to be sodded around the buildings and the larger play area to be seeded. We will include additional foundation plantings around the buildings in the final Iandscape plan to be submitted for permitting. The Drainage Plan shows the existing drainage pattern on the existing site will be maintained—the site slopes from north to south with part of the flow being diverted west of the 23 unit building and part of it draining at the existing driveway. All existing water drains directly into the ditch in Highway 10. We are not significantly changing the pervious/impervious surfaces for the existing development. Paramount Engineering has calculated the additional runoff front the new development on the east portion of the site. This runoff will be captured in the ponding area at the southeast corner of the site. The pond will be sized for.2 AF of storage for water quality • treatment and an additional.31 AF for a 100 year event. The.2 AF will be contained in the ponding area southeast of the 6-unit building while the ponding area for the I00 event will extend north of the building and possibly over the drive area south of the building(as shown by the dotted lines). The ponding area will be piped to drain into the ditch to flow west to the existing 15" pipe under Highway 10. Please call Bob Weigert at Paramount at 771 0544 if you have additional questions on the drainage issues. Please call me if you have questions or require additional information. o;:..2:7.---_ ter J.
