It Vl^bfite; WWW bonestroo com Dear Wendy. We have reviewed the preliminary plans for the proposed Lakeview Town Office Park. The site is located just west of Orono Senior Housing site in the northwest quadrant of Wayzata Boulevard (T.H. 12) and North Brow n Road. We have the following comments with regards to engineering matters: I. 2. 3. 4. 5. Traffic: The proposed access road grades on the east and w est sides of the site exceed 12%. This is exceptionally steep and wc recommend street grades be revised not to exceed 8%. Stop signs should be installed tor vehicles eastbound from the subject site at the intersection of the access road from T.H. 12. Streets and parking areas should be constructed to the City’s commercial/industrial street section as per City Standard Detail STR-7. All streets and parking areas shall have B6I8 concrete curb and gutter. Grading: We recommend that parking lot grades not exceed 4%. The proposed removal of the existing timber retaining wall along the west side of the site is on the adjacent property. Easements will be required for the retaining wall removal and the construction of the new retaining wall. All retaining walls over 4-feet in height require an engineered design and details. All silt fence must be in place prior to any grading activity. The applicant should provide an overall site plan showing building elevations so the City evaluate building l«eigl>ts arid ai^pearar.ee fivun the nort'n and souui. Drainage: A drainage area map and storm sewer calculations should be provided for our review. Plans should be submitted to the Minnehaha Creek Watershed District for their review. The applicant should provide evidence that the downstream storm sewer has the capacity to serve the new proposed use. I'ttlitics: The proposed sanitar>' sewer design appears acceptable. The City should be notified \.hen the sewer and water connections will be made to the City facilities. Water main connections shall be by cutting in a tec, no wet taps are permitted. Final plans should include sanitary sewer, storm sewer and water mam plan and profile view’s. 1 lydrants should be located at all dead end lines and at all high points. Fa»eiiu'iils: New utility easements will need to be provided for all constructed water main, sanitaiy and ^toml sewer. Drainage easeinenl.s should be provided across any existing or proposed drainage ways. Drainage and utility easements should be provided 10-feet wide along all lot lines. A final plat should be submitted for review. 23J5 West Highway 36 • St. Paul, MN S5I13 • 651-636-4600 ■ Fax: 651*636*1311
