Regional detention can be constructed in stages (with staged construction at a <br />single site or by use of multiple sites), thus lessening initial construction costs. <br />. Regional detention provides a mechanism for cost recovery; sale of detention can <br />be established to either recover incurred costs or incurred costs with additional <br />surcharge to recovery other drainage improvement costs. <br />. The availability of regional detention can be an attractor for new development. <br /> <br />If regional detention were to be employed, a cost recovery strategy could be based upon <br />1) initial funding being provided by the City to provide some detention to address certain <br />existing drainage problems; 2) allowing early purchase of surplus detention by <br />developers to reserve detention space in the detention system so that it is present when it <br />is needed for the development; 3) establishing a fee for purchase which is sufficient to <br />ultimately recovery both upfront costs and expansion costs; and 4) encouraging use of <br />regional detention by establishing a development fee on development which uses on-site <br />detention rather than purchasing storage in a regional facility. <br /> <br />5.2.9. Existing Detention Issues <br /> <br />Detention for remedy of existing flooding problems will generally be required as part of <br />the mitigation of increased channel conveyance when channel improvements are made to <br />address current flooding problems if downstream impacts are to be avoided. Potential <br />detention pond sites have been identified for such mitigation (see Exhibit 4-1, 4-2, and 4- <br />3). <br /> <br />Detention can be used to address anticipated future increases in runoff due to <br />development, as discussed in the preceding section. Some of this regional detention <br />could be also be constructed to alleviate some current drainage problems, but at costs <br />which are anticipated to be more than other options selected (i.e., channel improvements). <br />One large site currently available but undeveloped is a site located on property south of <br /> <br />5-15 <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 />
