Re; Professional Properties of Orono . File No. 139-02-000 Plat No. 02-2782 Dear Mike: We have reviewed the development plans for the Professional Properties building. The site is located at 2765 Kelley Parkway in the northeast quadrant of the intersection of Ch: Crystal Bay Road and TH 12. The proposed use of the site is for a dental/medical coii;pt«- Wr have the following comments in regards to engineering matters. 1. Sanitary Sewer: The sanitary sewer service is shown connecting to an existing manhole along Old Crystal Bay Road. The proposed 8-inch PVC service pipe will connect at the existing manhole invert elevation of 1006.4. The developer may want to install the service pipe at a grade of less than I % between the building and the existing manhole to minimize the excavation depth for the service pipe. This will require the construction of an outside drop at the existing manhole. Final plans should include profile views of the sanitary sewer. The plans should also include ' typical sections for trail and street repair. All repairs to the trail and street shall be made immediately after they are disturbed. 2. Water Main: The proposed water main design appears acceptable. The proposed connection to the existing water main stub should be coordinated with the City and instiled in accordance with City standards. 3. Storm Sewer/Grading: The proposed sturm sewer is shown discharging east of the site. The proposed pipe invert is something less than 1014.93 (proposed upstream invert at CBMH-5). Based on existing topography the discharge pipe invert elevation will be 5 to 6-feet under ground. The applicant should provide additional detail as to how this storm sewer system will work. Riprap should be provided at all outlets. The southwest comer of the site should be graded so drainage is directed easterly into the existing MN/DOT ditch. The existing culvert under Old Crystal Bay Road should be bulkheaded and abandoned. The proposed grading plan shows grading within the MN7DOT right-of-way. Plans should be submitted to MN/DOT for their review and approval. The proposed grading plan shows grading and parking lot construction on the adjacent property to the east. The applicant should verify they have control over this parcel and include additional grading information to identify how drainage will be handled on this site. 2335 Weit Highway 36 ■ St. Paul.
