title
Request for approval to amend a professional services agreement with Arcadis U.S., Inc. for Construction Phase Services in the amount of $17,643.00 in connection with Fountainview Sec. 1 & 2 Subdivision Drainage Improvements - 2018, UPIN 19101MF12F01, Precinct 1.
end
Background and Discussion:
The Fountainview Subdivision 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 project 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. 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. The proposed solution includes upsizing existing storm sewer to convey the 2- year storm event and incorporating a detention pond to mitigate increases in flow prior to outfalling into P133-00-00.
The proposed upsized storm sewers within the public right of way, conflict with a sanitary sewer owned by Central States Water Resources LLC (CSWR). Various alternatives have been reviewed to resolve the conflict. The most effective solution required a redesign of a segment of storm sewer to a shallower profile to avoid the conflict.
The Engineer of Record will continue to provide engineering services during the construction phase to ensure that the redesign meets project requirements.
Expected Impact:
Executing this agreement amendment will ensure that the utility conflict between a sanitary sewer and proposed drainage improvements in the construction phase, are monitored in accordance with the project objectives.
Alternative Options:
Alternative options include choosing not to execute this amendment, possibly not completing the project as designed.
