e CIlY OF LA PORTE, TX CRS ACTIVTIY 510 FLOODPLAIN MANAGEMENT PLAN e West La Porte Brookglen/College View All of the drainage in this area is a curb and gutter system. The majority of the losses are on cul-de-sacs, where the water runs the length of the block to a catch basin. When Flood Control Ditch #B-112 crests, the water in the subdivision backs up, especially in the cul-de-sacs. SpenwicklSpencer Highway Estates The flooding in this area was predominately caused by a 300-foot ditch that was dug in the middle of the block from Bayer to Flood Control Ditch #8-112-02. Harris County originally dug the ditch on private property. In 1996, after the City of La Porte annexed this area, we did a complete reconstruction project. The City of La Porte obtained authority to dig out this channel therefore alleviating flooding problems. When 8112-20 crests, though, there is still a slight delay in the run-off. 8rookglen was annexed as part of the College View M.U.D. with Ordinance #1400 on 2/15/1985. Spencer Highway Estates was annexed as part of the Spenwick M.U.D. with Ordinance #1396 on 1/4/1984. These subdivisions were therefore built under the jurisdiction of Harris County and not subject to the regulations of the City. Upon annexation by the City of La Porte, all nonconformities with city ordinances are dismissed or "grandfathered." However, any substantial improvement or substantial damage to structures in the area now would require full compliance with the City's Flood Damage Prevention Ordinance. The subdivisions in west La Porte are subject to significant peak runoff rates from developed upstream areas. The City and HCFCD are studying mitigation action for this area.
