According to a drainage study conducted by Klotz Associates in 2009, the existing Bayside Terrace Subdivision was identified as having 3-year Level of Service (LOS), using old rainfall data. The existing drainage system consists of roadside ditches and underground reinforced concrete pipe ranging in size from 12-inch to42-inch. Halff Associates, Inc. (Halff) was commissioned, in 2020, to evaluate the existing drainage conditions within the subdivision and to provide recommended drainage improvements to accommodate a 100-year rain event. Halff has completed approximately90% of the final design of the proposed project, providing an opinion of probable construction cost of $6,947,215.00. Funding for the Bayside Terrace Subdivision Drainage Improvements Project has been allocated within the budgets for a total current project allocation of $5,405,000.00. On December 31, 2020,Harris County Precinct 2 began accepting applications for potential Capital Improvement Projects (CIP) and maintenance projects to be funded in partnership with other area agencies to serve the citizens of Harris County. The program provides funding for study, final design, right-of-way acquisition and construction of capital and maintenance projects. City staff submitted the Bayside Terrace project to Harris County for consideration, and received confirmation that Harris County selected the project to receive partnership funds. As outlined in the terms of the attached proposed inter-local agreement (ILA), Harris County would provide funding for 50% of all drainage related components of the project. The total anticipated project cost of $7,336,458.75is ascribed to: $6,945,172.30 construction costs (including a 10% contingency); $252,383.00 engineering costs; $138,903.45 material testing costs. Each of the respective costs will be split between the City and County 60/40; 100/0; and 50/50, respectively. The non-50/50 splits are due to the inclusion of non-drainage related components within the costs. The City of La Porte had entered into professional
