CSAH 14, I-35W to I-35E Water Resource Meeting Minutes -7- January 5, 2005 . The FIRM elevations north of Mound Trail were discussed noting that the FIRM shows the existing roadway within the 100 base flood elevation. The County stated that the roadway has not been flooded (at least in the last 25 years according to County Public Works records). Several resources were referred to that documented the floodplain elevations: - Rice Creek 1998 Calibration Study (Modeled in 1992 for 10 day snowmelt)=887 - DNR record=886.7 Watershed District concluded that the elevation of 886-887 should be used. SRF requested that after calculating the volume of impact, we meet with the Watershed District to discuss hydrologic mitigation options. Hydrologic mitigation may involve modeling. The City of Lino Lakes requests to be involved in these discussions. . The meeting participants discussed the Floodplain Reduction Plan (1994) that was completed for the area near 20th Avenue. Resource Strategies Incorporated (Dean Johnson) is a good reference for this work. · The proposed bridge work at George Watch LakeIPeltier Lake was described. The existing bridge provides a 25-foot opening at the connection and the proposed bridge will provide a 9O-foot opening. There will be 10-foot clearance from the bottom of the bridge to the proposed trail that will pass under the bridge. The trail under the bridge will provide access from the south side of CSAH 14 to the proposed canoe launch, fishing pier and parking lot on the north side. There would be 2 to 3 feet from the trail to the normal water level. A single span bridge is currently proposed because of constructability, compatibility with the waterway and accommodation for wildlife crossing. The meeting participants stressed the importance of not opening the connection so much as to drop the water levels, which would impede canoe use. The DNR will be consulted for purposes of fisheries; however, it is believed that with the upstream dam, this is not a concern. 5. Future Meetings A future meeting will be arranged with the TEP in Spring 2005. SRF and the County will arrange a meeting with the Watershed District in January 2005 to discuss stormwater treatment and floodplain impact mitigation These meeting minutes were prepared by SRF Consulting Group, Inc.
