k I o t z associates <br />To maximize the effectiveness of proposed drainage improvements and minimize future drainage <br />problems, the City should rigorously enforce drainage criteria and standards. Future finished <br />floor slab and critical roadway elevations should be established. Provisions for sheet flow relief <br />pathways and assurance of adequate capacity in new sewers systems which meet upgraded City <br />criteria should be enforced. Construction in flood hazard zones and flood -prone areas should be <br />avoided as much as possible. And, to the extent that they are not already in place, agreements <br />need to be developed between the City and HCFCD to assure adequate levels of channel <br />maintenance to maintain channel conveyance. <br />Implementation of recommended projects can initially focus upon very cost efficient, less <br />expensive projects such as relief swales, which can be relatively easily implemented. Larger, <br />more complex projects to address flooding problems along channels as well as detailed analysis <br />of some storm sewer systems should follow. The more complex flood protection projects will <br />require more effort to implement, but will provide a high level of flood protection. Selection of <br />the more cost efficient alternatives will usually facilitate project implementation. Impacts of <br />recommended improvements should be recognized and appropriate mitigation implemented. <br />Regional detention opportunities should be explored when impacts lie or have their source <br />beyond City boundaries. <br />Projects can be implemented individually and are not contingent upon each other; sequencing of <br />projects can be used to implement a series of projects over time. While guidance has been <br />provided to assist in deciding which projects should receive priority for implementation, the <br />decisions as to the priorities for construction of improvement projects is, in the final analysis, the <br />responsibility of City leaders. <br />EN 15 <br />Klotz Associates Project No. 0127.008.000 La Porte Citywide Drainage Study <br />January 2009 City of La Porte <br />
