is higher than the streets connecting to it, this project should be considered low priority and may not impart any immediate benefit until further improvements along Fleetwood are implemented (i.e. lowering the street). The cost for this project would be approximately $30,000 and would use pipe bursting technology. More research is necessary. 5) The intersection of Spencer Highway and Valley Brook Dr. appears to be a high point which allows ponding water trying to drain off of Spencer Highway to sheet flow into the Glen Meadows Subdivision and adding to the volume of water already draining from the streets of that subdivision into Big Island ` Slough. Since the drainage system associated with Spencer Highway is designed to drain from the street into Big Island Slough, Staff is suggesting to Harris County that an interceptor inlet be added to the system just West of that intersection and along the North curb line at the foot of the bridge going over Big Island Slough. This interceptor inlet would allow water to drain off Spencer Highway directly into the storm sewer and discharge from the box culvert outfall structure as intended. Staff is also coordinating an addition to the outfall structure at Spencer Highway and Big Island Slough to account for additional sheet flow for major rain events. The total estimated costs for these projects range from $110,000 to 165 00 epending on further analysis and design. A Notice of Interest (NOI) is being forwarded in hopes to secure grant funding from the latest disaster declaration. This funding may be used as a reimbursement should Council direct Staff to proceed with design and funding recommendations. The Planning Department, in coordination with the Public Works, Parks and Police Departments is researching surrounding city ordinances to determine the best method, practices and enforcement to control and prevent speeding traffic from flooding homes due to the wakes being created. Results will be presented to the Committee at their December 3, 2007, meeting. Action Required by Council: Direct and guide Staff on how to proceed with the analysis, design and funding recommendations for the short term drainage projects reviewed by the Flooding and Drainage Committee.
