Panatonni Development Page 4 September 17, 2003 City of Lino Lakes, Minnesota 2. The bottom of the proposed pond furthest upstream (Pond 5) is well below the groundwater level as shown in the geotechnical report. It is recommended that the capacity of the pond be further reviewed. 3. High water elevations for the existing wetlands are not shown. The information submitted does not indicate if the wetland elevations will rise or be impacted by the proposed construction. In addition, the school pond must be modeled for existing and proposed conditions. The existing conditions appear to be correct while the proposed condition must be revised accordingly. 4. The wetland and Pond 5 should be modeled separately (not combined) to determine their respective flood elevations. Per the September 3 response letter from Glenn Rehbein, it is stated that Pond 5 and the wetland are linked with a ditch. However, no such ditch is shown. 5. Storm sewer computations have been provided and are under review. 6. An average of SCS Type A and Type B soils should be used to determine curve numbers for the proposed conditions. 7. The existing condition curve numbers and times of concentration utilized are acceptable. 8. As previously stated, approval of the Rice Creek Watershed District should be attained prior to the City granting final approval. Utility Plan Further utility comments are as follows: 1. At the west side of the property, it intended to connect the watermain to the existing 10 -inch main, either to an existing stub, or wet tap directly to the existing 10 -inch main. In any event, a proposed 12 -inch line will be connecting to an existing 10 -inch line, and the location and type of connection must be identified very clearly. A valve must also be installed at the point of connection. The sanitary sewer proposes connecting to an existing manhole along the west side of the property that is shown connecting to an existing 12 -inch trunk main. This connection must also be labeled and identified clearly on the plan. The manhole and invert must be field verified. 2. Watermain is proposed to be looped around the building. The number and location of fire hydrants sown shall be subject to approval of the City Fire Chief. Note 10 should be revised to state that installation and testing of all sanitary sewer and watermain shall be conducted in accordance with the requirements of the City of Lino Lakes, specifications of the City Engineers Association of Minnesota, the Minnesota Department of Health, and the Minnesota Pollution Control Agency as required. 4. The proposed sanitary sewer and water mains should be shown with a heavier line to distinguish them easier from the existing mains.
