REQUEST FOR DRAINAGE COMMITTEE AGENDA ITEM Agenda Date Requested: July 9, 2018 Requested By: Lorenzo Wingate Department: Public Works Report: w " Resolution: (D Ordinance:( Exhibits: Appropriation Source of Funds: Account Number: Amount Budgeted: Amount Requested: Budgeted Item: y " YES (D NO SUMMARY The segment of 6th St from W. Madison St to W. Main St is considered part of Old La Porte, which was generally noted in the City -Wide Drainage Study as not having sufficient storm sewer capacity due to undersized storm sewer, undersized storm inlets, and/or not enough storm inlets. RPS-Klotz provided an analysis of the existing storm sewer system with results indicating that 6th St, from W. Madison St to W. Main St, has significant ponding in storm events as low as 5-year event. Recommendations for improvements were provided, however, areas would still experience ponding depths of approximate 6" to 2'. Thus, additional efforts are required to understand the root cause of flooding in the area and to recommend improvements to reduce flood risk within the area. The GLO-CDR has allocated $325,775.30 to the City of La Porte through Harris County's initial MOD and MOD Amendments No. 1 and 2 from the 2015 Floods CDBG-DR funds. Now, to access the funding allocated to the City of La Porte, GLO requires submission of a Non -Housing Project Application detailing the City's proposed non -housing project to repair or mitigate damage that occurred during the Presidentially declared Federal Emergency Management Agency (FEMA) 4223-DR-TX (2015 Memorial Day) and FEMA 4245-DR- TX (2015 Halloween) disasters. Staff has been working with the GLO to ensure that these funds are captured, with plans to utilize the allocation to supplement the project budget. Preliminary proposed project cost is estimated to be $2.5M. Action Re quire d: Approved for Drainage Committee Agenda Corby D. Alexander, City Manager Date
