INFORMATION:

The Board of Aldermen (BOA) asked staff to provide periodic updates on the Storm Water Mitigation projects. Updates have been provided on February 11, 2014, May 20, 2014 and September 16, 2014. The abstracts from the previous updates can be found as attachments.

Preliminary engineering studies and cost estimates have been completed by Sungate Design, Inc. for six project locations at a cost of $26,500. The preliminary estimates were included as part of the FY 15/16 Capital Improvement Plan (CIP) and are included as an attachment. Also included as an attachment is a summary table providing a description of proposed improvements, cost estimates for design and construction, and comments about flooding impacts and priority.

How these projects are to be funded still needs to be determined. At this point in time funding has not been budgeted as staff looks at possible funding options. The two options noted in the CIP are: 1) pay as you go, 2) Assessment. One of the purposes of this report is to discuss the idea of assessing properties upstream of the proposed improvements which contribute storm water.

The six locations that have been studied are shown below with updates.
