<br />a) A preliminary drainage analysis that includes drainage area maps and the calculation <br />of the existing 2, 10,25 and 100 year flow. Engineer will include drainage areas <br />from the analysis outlined below for both the City and TSUSM. The Engineer will <br />utilize the HEC-1 or HEC-HMS hydrologic modeling software to determine flow <br />rates and StormCAD hydraulic modeling software for storm sewer design. <br /> <br />b) A preliminary cost estimate. <br /> <br />1.2.8 Conduct a drainage analysis as described in Section 1.2.7 above to determine the amount of <br />runoffthat can be diverted from the proposed storm sewer into a water quality pond on the TSUSM <br />campus. <br /> <br />1.2.9 Conduct a preliminary drainage analysis as described in Section 1.2.7 above to determine the <br />amount of runoff from the existing 60 inch storm sewer that can be diverted into a water quality pond <br />on the TSUSM campus. Engineer will ensure that remaining runoff will be directed into the existing <br />outfall at the San Marcos River. <br /> <br />1.2.1 0 Work with TSUSM to prepare a preliminary design to transform an existing pond( s) into a <br />water quality pond that will filter the storm water from this Project prior to being released into the <br />San Marcos River. The Engineer will utilize the Texas Commission on Environmental Quality's <br />("TCEQ") Best Management Practices (BMPs) in the design of the water quality pond. Engineer <br />will provide in this analysis the results of any investigations into the adverse effects the Project will <br />have on the San Marcos River and further provide recommendations of possible mitigation as <br />necessary. <br /> <br />1.3 TASK 2 -FINAL DESIGN <br /> <br />The Engineer will: <br /> <br />1.3.1 Meet with the City's Project Manager periodically or as needed to update the City on the <br />progress of work (two meetings anticipated). <br /> <br />1.3.2 Head the Project team and coordinate the integration of design, surveying, right of way <br />issues, traffic control, utility Engineering, permitting, and other services as previously approved. <br /> <br />1.3.3 Attend one meeting with project stakeholders. <br /> <br />1.3.4 Prepare final Project plans that will incorporate the storm sewer plans for both the City and <br />TSUSM. These plans will include: <br />a) drainage plan and calculations <br />b) storm sewer plan/profile sheets <br />c) cross drainage plan/profile sheets, if necessary <br />d) water quality pond <br /> <br />3 <br />
