About this file
This is a set of construction drawings for concrete channel repairs at Halls Bayou (Project P118-09-00-X014) prepared for the Harris County Flood Control District (HCFCD) in Houston, Texas. The project involves repairing approximately 2,800 linear feet of concrete-lined channel from Station 12+00 to Station 39+62, with work including removal and disposal of existing concrete channel lining (3,513 square yards), riprap (2,151 square yards), and concrete bottoms, followed by installation of 8-inch nominal thickness concrete channel lining (5,340 square yards) and riprap gradation No. 2 (1,176 square yards). The construction scope encompasses site preparation, clearing and grubbing, excavation and fill operations (totaling 2,681 cubic yards of cut and 564 cubic yards of fill), installation of five cast-in-place headwall and wingwall structures at existing culvert locations, storm sewer pipe installation (18-inch, 30-inch, and 36-inch reinforced concrete pipe), geotextile filter material, turf establishment through sodding and hydromulch seeding, stormwater pollution prevention measures, and temporary erosion control features. The project requires adherence to Harris County Flood Control specifications and includes provisions for utility coordination with CenterPoint Energy, AT&T, Magellan Pipeline Company, and other existing underground and overhead facilities.
The 42-sheet drawing set includes plan and profile views, cross-sections, typical details for channel lining and riprap placement, culvert structure details with reinforcement specifications, and stormwater pollution prevention plan details. Key design specifications call for Class C concrete with minimum 3,600 PSI compressive strength, Grade 60 reinforcing steel, and riprap installation per HCFCD standards. The project incorporates best management practices for construction sequencing, including limiting channel disturbance to maximum 1,500 linear foot segments and establishing completed sections for revegetation. Construction access is provided at three locations (Bigwood Street, Parker Road, and Gleason Road) with temporary access easements and stabilized construction access points. Environmental considerations include tree and plant protection zones, migratory bird nest habitat surveys, and wetland protection measures. The drawings reference geotechnical recommendations from a September 2025 addendum report prepared by Cibor Geoconsultants and specify compliance with Texas Pollution Discharge Elimination System (TPDES) general permit requirements under the Clean Water Act.

8. CLEAR AND REMOVE ALL SILT FROM CULVERTS, PIPES AND UNDER BRIDGES TO THE PROPOSED DESIGN GRADES TO
PROVIDE POSITIVE FLOW.
9. LENGTHS AND DIAMETERS REPRESENTED ON PLANS ARE APPROXIMATE. CONTRACTOR WILL BE RESPONSIBLE FOR
FIELD VERIFICATION PRIOR TO ORDERING MATERIALS.
10. ACTIVITIES THAT DISTURB BIRD HABITAT, INCLUDING BUT NOT LIMITED TO CLEARING, GRUBBING, AND IMPACTS TO STRUCTURES WHERE MIGRATORY BIRDS AND BALD EAGLES MIGHT NEST, REQUIRE A NEST HABITAT SURVEY. DO NOT PROCEED UNTIL HARRIS COUNTY FLOOD CONTROL DISTRICT HAS CONDUCTED A NEST HABITAT SURVEY TO VERIFY ACTIVE MIGRATORY BIRD NESTS AND BALD EAGLE NESTS ARE NOT PRESENT.

IN AREAS OF VOIDS ONLY, THE SURFACE FROM WHICH THE 2 FEET DEPTH IS MEASURED WILL BE THE LEVEL OF THE SURROUNDING UNDISTURBED SOIL. IN AREAS OF RILLING, THE RILLS WILL FIRST BE KNOCKED DOWN AND LEVELED OFF. THE 2 FEET DEPTH WILL THEN BE MEASURED FROM THIS NEW
SURFACE. THE CONTRACTOR WILL DETERMINE THE MEANS AND METHODS FOR DEEP PLOWING.)
14. TREES AND PLANTS LOCATED WITHIN A DESIGNATED TREE PROTECTION ZONE (TPZ) SHALL BE PRESERVED. REFER TO SPECIFICATION SECTION 01566 - TREE AND PLANT PROTECTION, FOR DETAILED INFORMATION ON TREE AND PLANT PRESERVATION PRACTICES AND PROCEDURES INCLUDING, BUT NOT LIMITED TO, ROOT PRUNING, VEGETATION

SEPT 15,2025. THE REPORT IS APPROVED BY HCFCD.
MAINTENANCE ENGINEERING CONSTRUCTION NOTES
1. THE PROJECT PLANS ARE INTENDED AS A GUIDE. THE REPAIR AREA LIMITS WILL BE DETERMINED IN THE FIELD BY THE HCFCD REPRESENTATIVE. DUE TO THE DYNAMIC CONDITIONS IN THE FIELD, PROJECT SCOPE AND QUANTITIES MAY VARY FROM THE PLANS AND/OR CROSS SECTIONS. HCFCD RESERVES THE RIGHT TO ADJUST PLANS AND QUANTITIES AS NECESSARY. PROJECT SCOPE MAY BE
ADJUSTED AS PRIORITIES CHANGE.
2. THE PURPOSE OF THE CHANNEL DESILT IS TO RESTORE POSITIVE DRAINAGE DURING LOW FLOW CONDITIONS. UNLESS SPECIFICALLY STATED OTHERWISE, IT IS NOT THE INTENT OF THE PROJECT TO DEEPEN THE CHANNEL BEYOND ITS ORIGINAL DESIGN CONFIGURATION.
EXCAVATION OF SILT SHOULD NOT UNDERMINE THE TOE OF THE SLOPE.
