klotzOlassociates <br /> Mr. Julian Garza Jr., P.E. <br /> July 5, 2011 <br /> Page 5 of 7 <br /> conveyance capacity of the existing system and to determine the required additional <br /> capacity to reduce structural flooding for Battleground Estates. <br /> Task #7 -- Analyze Potential Alternatives: <br /> 1. For the identified problem areas along the drainage channels, study and analyze <br /> alternatives for drainage improvements, with an initial focus of channel improvements, <br /> driveway culvert replacement/improvements, downstream culvert replacements, <br /> detention, other structural improvements to portions of the watershed and any needed <br /> mitigation. <br /> 2. Determine the additional drainage right -of -way requirements for the improvements <br /> described in items above. A maintenance berm requirement around any planned channel <br /> improvements where required and on both side of channel improvements will be <br /> evaluated for determining needed right -of -way. <br /> Task #8 - Report Recommendations <br /> 1. Prepare construction cost estimates and implementation plan for the feasible alternatives. <br /> 2. Evaluate benefits and costs. <br /> 3. Provide recommendations for drainage improvements. <br /> 4. Prepare a Preliminary Engineering Report that documents the items described above and <br /> includes supporting data as applicable. This report is intended to be used in conjunction <br /> with the previously prepared Master Drainage Plan. The report will include text, tables <br /> and exhibits along with some supporting data. A goal of this report will be to minimize <br /> channel construction or improvements and to develop a program that could be <br /> implemented by the City. The cost for the recommended improvements may exceed the <br /> available funds of $900K from the City. A phased approach may be recommended to the <br /> City to allow for some improvements to be considered for construction now and to <br /> provide some thoughts for implementation of future drainage improvements. <br /> 5. Present ten printed copies and a PDF version of the draft plan to staff and council for <br /> review and comments. <br /> 6. Incorporate applicable changes to the draft report and models from council and staff <br /> comments. <br /> 7. Submit ten printed copies and PDF version of the final report to the City for distribution. <br /> 8. Attend monthly meetings, perform project management and conduct quality control. This <br /> will include a workshop with Council. This scope does not include meetings where the <br /> final recommended plan is presented to Harris County nor to Harris County Flood <br /> Control District. <br /> ESTIMATED BUDGET <br /> A cost with a not to exceed amount of $166,420 is recommended for the above services <br /> which also includes engineering, surveying costs, soils investigation costs and environmental <br />
