For this subwatershed the model has not yet been completed but future plans are to do so. The leadership team, as well as many agencies, feel that modeling will not pinpoint targeted areas in need of BMPs but rather urban issues such as open space, willingness of citizens to alter habits, and local government input will drive stormwater management, wastewater nutrient reduction numbers, and reduction goals as the urban factor is the largest contributing factor in these subwatersheds. The urban BMPs to be installed within the Hays Consolidated subwatershed will include retention ponds, native vegetation in drainages, and stormwater education at the discretion of the stormwater superintendent. Other BMPs outside of the City of Hays limits will focus on traditional practices that retain, filter, or infiltrate stormwater. For a comprehensive list of BMPs see Table 13. Table 13.
