AGENDAITEM <br />Item No.: <br />Item Description: Stormwater Pond Assessments <br />Date: April 24, 2017 <br />Presenter: Adam T. Edwards Agenda Consent Agenda <br />Public Works Director/City Engineer Section: <br />Purpose. The purpose of this action item is to gain Council authorization for Bolton and Menk to conduct <br />a Stormwater pond assessment for the French Lake (FR), Lake Classen (LC), Maxwell Bay (MB), and <br />Stubbs Bay (SB) Subwatersheds. <br />1. Background. In order to maintain compliance with the MS4 permit one of the action items in the <br />City's Storm Water Pollution Prevention Plan is to develop a Pond Assessment Program. The plan covers <br />the years of the MS4 permit (2015-2020) and calls for a deliberate process of gathering/ verifying cur -rent <br />data on our ponds and then using that data to determine their effectiveness in removing total phosphorus <br />(TP) and total suspended solids (TSS) from our storm water. To complete the process we divided the <br />city into its various subwatersheds with the goal of completing the assessment of a couple sub watersheds <br />per year. In 2016 we started with Long Lake (LL) and Tanager Lake (TL) sub -water sheds. <br />2. Project Scope Assess the stormwater ponds in the French Lake (FR), Lake Classen (LC), Maxwell <br />Bay (MB), and Stubbs Bay (SB) Subwatersheds to include the delineation of their watersheds, <br />determination of pond watershed characteristics and the characteristics of the ponds themselves. <br />3. Cost. Bolton and Menk provided a not to exceed estimate of $10,000 for the assessment (Exhibit A) <br />4. Funding. The assessment will be funded by the Storm Water Fund. <br />Fund <br />Project Total <br />CIP Programed <br />amount <br />EOY 2016 Est. <br />Fund Balance <br />Storm Water Fund <br />NTE $ 10,000 <br />$ 10,000 <br />$ 1,077,861 <br />5.
