Recognize, however, not all bayous and streams in <br />the City were studied under the TSARP program for the purpose of base floodplain <br />delineation; watercourses for which neither in-channel nor out-of-bank flooding <br />conditions are shown are watercourses (or portions of a watercourse) for which no FEMA <br />hydraulic model has been developed. <br /> <br />2.3.2 Drainage and Flooding Problem Identification <br /> <br />While FEMA-delineated floodplains and the models used for such delineation can be <br />used to estimate or identify areas of potential flooding problems, other techniques can <br />and were also used to identify flooding and drainage problem areas. These latter methods <br />included direct inspection and observation, discussion with knowledgeable persons on the <br />City staff and City Council, citizen reports to the City on severely damaged structures, <br />drainage and flooding problems arising from Tropical Storm Allison and Tropical Storm <br />Erin, flooding data documented by citizens, and fonnal repetitive loss reports (i.e., <br />multiple reports of flood damage to structures made for flood insurance claim purposes). <br />These latter reports define what are termed repetitive loss data. <br /> <br />The City's repetitive loss data were obtained for this study at the request of the <br />Floodplain Administrator for the City and used to approximately locate where structural <br />losses (e.g., residential houses) were occurring. Repetitive loss data help not only <br />identify the location of the flooding problems but are important to identifying recurring <br />and long term problem areas. <br /> <br />The agglomeration of these locations in combination with other information on flood <br />damage locations can be used to identify areas (referenced by the subdivision in which <br /> <br />2-6 <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 />
