Agenda - Public Works Committee - 01/20/2015

Home

A map was prepared by staff showing historical areas that had experienced high water. This map was incorporated in the Surface Water Management Plan. 2011 The 2010 — 2011 winter saw high snowfall. The City received 22 complaints about high water in backyards. Staff determined that the complaints fell into 3 categories: A - Water ponding outside of easements B - Water ponding in public right of ways, and C - Water ponding in drainage and utility easments. Studies were prepared for properties in the A category and several projects were approved for correcting the drainage problems. Several more projects that were studied were postponed for budgetary reasons. Properties in the B category were slated for inclusion in street maintenance projects in the area, the work generally consists of replacing failed culverts. Review of properties in the C category indicated the water was contained in the drainage and utility easements, downstream culverts and channels were checked, no further action required. 2014 Staff received several complaints regarding high water on properties. Council members also received calls from property owners. The affected residents have been notified that their concerns will be brought forward at the February Public Works Committee meeting. Timeframe: Estimated time for this discussion is 20 minutes. Observations/Alternatives: The City has responded to high water concerns in various ways in the past. The attachments include memos and council meeting minutes and a lists of properties reporting flooding concerns. A map will be projected at the meeting. Funding Source: Specific improvements are not proposed with this case. The funding source for the 1985 actions was not specified. Storm water improvements after 2000 have been funded from the Storm Water Utility account. There are increasing demands for stormwater improvements including resident concerns as noted above and construction of storm sewer in conjunction with street reconstruction projects and annual maintenance. A comprehensive look at projected expenditures from the Storm Water Utility account is needed. This will be initiated with the case brought to the February Public Works Committee Meeting. Recommendation: Staff recommends reviewing the attached information in preparation for the February meeting. No action is required on this case. Action: This case provides background information on how the City has addressed flooding concerns in the past. No action is required at this time.
