Projects which address areas with a large number of flooding <br />reports are projects which would be recommended as having a high priority for <br />implementation; projects affecting areas with small numbers of flood reports should be <br />considered to have low priority and be considered for construction only after other major <br />problems are addressed. Generally, the lower the project cost and the higher the number <br />of flood reports being addressed by a project, the higher the priority for construction. It <br />should be noted that Table 5-7 orders the improvement projects based on cost, while <br />Table 5-8 orders the improvement projects based on number of flood reports. <br /> <br />Depending upon the cost of projects and the number of drainage reports in an area that <br />particular projects would address, a particular level of cost per number of reports might <br />be considered as a basis for defining a cut-off for consideration of a project to be <br />implemented. Such a cut-off criteria might dictate that some projects never be built; such <br />a conclusion should be recognized as an issue in setting priorities and selecting various <br />projects for implementation. <br /> <br />5.1.3 Priorities for Future Regional Detention Projects <br /> <br />In estimating needed detention storage, it should be noted that in order to determine the <br />benefits of existing developable land that might become developed in the future, <br />currently undeveloped land areas were assumed to become fully developed with dense <br />residential lots of a typical size of 0.25 acre. The increased flows and runoff volume <br />caused by the increase in development for tlle future conditions will be mitigated with the <br />construction of regional detention ponds. These regional detention ponds are intended to <br />address future problems. Also, the construction of regional detention ponds assumes that <br />the receiving streams have the needed improvements to efficiently convey the flows out <br />of and into the receiving streams. <br /> <br />5-4 <br /> <br />Klotz Associates Project No. 0127.008.000 <br />January 2009 <br /> <br />La Porte Citywide Drainage Study <br />City of La Porte <br />
