AGENDA ITEM — 1C <br />'It <br />-731�EN HILLS <br />MEMORANDUM <br />DATE: September 9, 2019 <br />TO: Honorable Mayor and City Councilmembers <br />Dave Perrault, City Administrator <br />FROM: Todd Blomstrom, Interim Public Works Director/City Engineer <br />SUBJECT: Shorewood Drive Drainage Improvements <br />Budgeted Amount: Actual Amount: Funding Source: <br />$ N/A $ N/A TBD <br />For Council Consideration <br />City Council direction regarding potential drainage improvements along Shorewood Drive. <br />Background <br />The Public Works Department has received multiple requests over the past two years to repair <br />drainage deficiencies along the northern portion of Shorewood Drive. This section of roadway <br />was resurfaced within the past three years, including the replacement of bituminous curb along <br />the full length of the roadway. However, no stormwater drainage improvements were included <br />in the resurfacing project, resulting in approximately 1,230 feet of roadway draining to a single <br />storm sewer inlet located in the center of the street at 3203 Shorewood Drive. <br />During rainfall events, debris is washed down the street and blocks the storm sewer inlet. Larger <br />storm events produce runoff which exceeds the capacity of the inlet, resulting in pooled water in <br />the street and overland flow being conveyed over the southerly portion of the driveway at 3203 <br />Shorewood Drive. <br />Staff has identified three potential options to address this drainage issue as listed below. <br />1. Installation of additional storm sewer catch basin inlets to the west of the existing inlet. <br />Page 1 of 1 <br />
