initiated a drainage improvement project, providing additional detention capacity, thereby allowing for local improvements to be made within the Brookglen subdivision. As a result, the CDBG-MIT project scope is revise is intended to provide overland sheet flow paths and increase the storm sewer collection system capacity to provide a level of service to accommodate the Atlas-14 100-year rain event. Potential improvements include: increasing storm sewer pipe capacity and level of service from a 3-year rain event, to the Atlas-14 100-year rain event by replacing approximately 7000 LF of storm sewer pipe (various sizes, 24" - 54"); replacing the existing 3-foot wide inlet openings with inlets having a minimum opening of 5-feet; creating overland sheet flow path(s) by reconstructing/regrading approximately 46,700 SY of concrete paving within the project area bounded by: Fairbrook Lane to the south; Willowspring Creek to the west; CenterPoint Energy powerline corridor to the north; and Gladwyne Lane to the east. The estimated total project cost is $11,400,010. Currently, the Brookglen Drainage Improvement project has a total project allocation of $2,775,000, which was prefunded within the City's FY19, FY20, and FY21 budgets. The project is intended to continue to be prefunded until the total anticipated project cost is amassed, including all funding sources. The City's CDBG-MIT application requests $4,000,000 in grant funding, which is consistent with the previous TDEM application request, leaving approximately $7,400,000 to be funded using local funds. Additionally, staff has submitted a partnership application to Harris County Precinct 2, requesting that the Precinct participate in a 50/50 cost -sharing agreement for the Brookglen project. If awarded both CDBG-MIT funding and Precinct 2 funding, the City and Precinct would split the project cost(s) not covered by the CDBG-MIT funds. The application protocol for the CDBG-MIT Program requires applicants to submit certification, such as a resolution to authorize the submission of the application for grant funds. The resolution identifies the Mayor and City Manager as "Chief Executive Officer" and "Authorized Representative" as signatory to act in all matters of the CDBG- MIT Program. Benefits: • Grant funds could offset City's project related expenses • Project focuses on the Drainage Committee's top prioritize project • Consistent with priorities identified within the Harris County Multi -Hazard Mitigation Action Plan • The City's Comprehensive Plan - 2018 Five Year Update prioritized twelve actions, with Infrastructure and Drainage Improvements listed as the top priorities. Liabilities: • Improvements are not fully funded. Not applying would further delay ability to fully fund the project. • Flood risk reduction is further delayed.
