Background and Discussion:
The project study area is bound by Harris County Flood Control District (HCFCD) Unit# P133-00-00 on the north, Aldine Bender Road on the south, HCFCD Unit# P133-04-00 on the west, and HCFCD Unit# P133-03-00 on the east. The majority of the study area is residential, comprised of single-family homes with concrete sidewalks and a curb and gutter storm sewer system. An evaluation of the existing storm sewer system showed that the existing storm sewer pipes do not meet current County criteria due to insufficient capacity to convey the 2-year storm event or have a diameter less than the specified minimum diameter size of 24-inches. In addition to the undersized storm sewer within the neighborhood, it was also determined that the receiving channels restrict the study area's ability to drain. During the 100-year storm event, flow from P133-00-00 backs up into the two tributary channels, P133-03-00 and P133-04-00. These tributary channels then cause the storm sewer system within the subdivision to fill up resulting in ponding within the neighborhood until water surface elevations in the channels recede and allow the neighborhood to drain.
