8. Programmatic and financing analysis <br />a. Regional stormwater program and drainage utility review as funding opportunities <br />b. Assess regulatory options and criteria manual in coordination with WQPP <br />9. Reports and meetings (project management) <br />10. San Marcos watershed protection program management <br />a. Coordinate /optimize activities with the HCP, WQPP, WPP, MS4 and Corps <br />efforts <br />Project Tasks <br />Collect data /maps /reports /GIS files from City staff <br />a. City GIS resources <br />b. Storm drain maps of existing systems including GPS data of all inlets and outfalls <br />c. Storm drain project list, recently completed and planned <br />d. Flooding complaint files, both creek and localized <br />e. Creek erosion complaint files <br />f. Downtown district maps, Smart Zone maps <br />i. City to initiate meeting with Gateway Planning <br />g. Meeting with City maintenance staff to gain their input on problem areas /facilities <br />h. Collect flood prone bridges /area information from Hays County <br />i. Existing Community Rating Service (CRS) program <br />2. Field reconnaissance, surveying and mapping <br />a. Visit with City maintenance staff at sites, review existing problem areas and <br />concerns <br />b. Coordinate with City staff to develop maps as necessary /exchange data <br />c. Survey bridges /culverts as needed <br />I Hydrology (creek and floodplain related) <br />a. Develop HEC -HMS models for Cottonwood Creek watershed (see Halff <br />document for study limit details as it illustrates the work being done for the GBRA <br />Flood Study) <br />b. Develop hydrographs for the existing 2 -, 5 -, 10 -, 25 -, 50 -, 100 -, and 500- year <br />storms <br />c. Develop hydrographs for the fully developed 2 -, 5 -,10 -, 25 -, 50 -, 100 -, and 500 - <br />year storms (propose full range of storms to match the GBRA Flood Study effort <br />and assess /prepare conceptual regional detention facility designs) <br />d. Coordinate with City staff to provide update on findings /approach <br />e. To prepare these models, work in concert with ongoing USACE /GBRA flood <br />study to ensure consistent approach in computing times of concentration, runoff <br />curve numbers, and model assumptions <br />f.
