k lot z 4~. ass 0 cia t e s the City along B109-00-00 on land owned by HCFCD and the city of Pasadena (see Pond Site 43 in Exhibit 4-1). Joint funding arrangements could be possibly made with HCFCD which could speed the development of this site under financial conditions favorable to the City. There is, in addition, currently a HCFCD regional detention facility (see April 1997, Wilbur Smith Associates, Consulting Engineers and Planners reference in Appendix A) along B112-02-00 in Deer Park about 2,000 feet north of Spencer Highway and north of the La Porte city boundary (see Exhibit 5-2). This pond provides mitigation of channel improvements in Deer Park north of the pond site as well as possible mitigation of runoff from future development north of the pond in Deer Park. There is a potential, albeit limited, that some surplus detention is available in this existing pond which could be allocated for regional detention needs in La Porte; discussions with HCFCD and Deer Park could be undertaken to assess this potential. There are also four potential regional detention sites (Harris County Flood Control District, Armand Bayou, HCFCD webpage) located south of La Porte (see Exhibit 5-2) being considered for development by HCFCD. The most northern of these has a potential to provide regional detention (to address current conditions or future development impacts) that may be beneficial to La Porte. Discussions with HCFCD need to be undertaken to assess the possibility of storage allocation in these reservoirs for the benefit of La Porte drainage and flooding mitigation. 5.2.10 Easements, Right-of-Way, and Land Acquisitions The CWDS anticipates that some easements and right-of-ways will have to be acquired. Because the CWDS is a planning level study, specific acquisition requirements were not identified. Channel widening, however, was keyed to stay within the existing bank line, thus possibly requiring only land for maintenance berms, if such easement does not 5-16 Klotz Associates Project No. 0127.008.000 January 2009 La Porte Citywide Drainage Study City of La Porte
