We have reviewed the plans for the proposed Orono Ice Arena located west of Old Crystal Bay Road and south of CSAH 6 in the southwest quarter of Section 28. We have the following comments relative to engineering matters. Utllltlca: Wc have reviewed the 1995 saniUry sewer flow measurements done by Metropoliun Council Wastewater Services for this area of the City. Based on their daU there appears to be adequate sewer capacity available for this facility. The City of Long Lake will be monitoring the wastewater flows in their system to determine if there is capacity available for additional units in Orono They expect to complete the monitoring by the end of May 1996. Assuming that the City’s Comprehensive Plan amendment is approved by the Metropolitan Council, both sanitary sewer and water main will need to be installed as shown on the plans. The applicant should either install these utilities or petition the City for the improvements. The wastewater should be pumped from a grinder pumping station through forcemain to the existing gravity sewer. The pumping station should be located near the driveway for future maintenance. Construction plans and specifications should be prepared for the pumping station, forcemain and water main, with as-built plans provided to the City upon completion. Drainage: The proposed storm sewer, stormwater pond, outlet structure and drainage calculations arc acceptable. The specifications .should be provided for our files. There is a wetland on the site which has been delineated. The wetland will not be impacted by the construction which is consistent with the Wetland Conser\ation Act sequencing which requires first avoidance, then minimization and finaUy replacement. The locations for erosion control measures should be shown on the plans. Access* The proposed access location and parking lot layout are acceptable. The parking lot provides 100 spaces which will not be adequate based on a seating 3. 2335 West Highway 36 ■ St. Paul, MN 55T13-3898 ■ 612-636*4600
