This is a bid set document prepared for the Harris County Flood Control District (HCFCD) related to offsite basin improvements for the Public Water, Drainage & Paving Improvements for Rocchi Road Extension project in Texas. The document contains engineering plans and specifications for excavation and drainage work, including detailed site maps with construction limits, filter dam locations, and coordinate data. The project involves clearing approximately 0.12 acres with a total proposed excavation of 815 cubic yards in this scope, building upon ongoing and completed work that includes 2.36 acres of clearing and 14,501 cubic yards of excavation. The plans reference project numbers P2206070053 and P2308170179, with benchmark elevations and survey point tables provided for contractor verification. The bid set was finalized as of July 30, 2026, and includes detailed point elevation data ranging from approximately 175 to 182 feet.

The contractor is responsible for all clearing, grubbing, dust mitigation during dry conditions, SWPPP compliance, and material disposal in accordance with HCFCD Standard Construction Specifications and Details. Critical requirements include maintaining a minimum 10-foot buffer from Waters of the U.S. and a 25-foot buffer from wetland areas, with site access restricted to designated routes only. Contractors must provide 48-hour advance notice to HCFCD prior to excavation, coordinate with Orange County Engineering for any required driveway permits, and conduct migratory bird surveys if tree clearing is necessary, with a 10-day window for clearing following survey approval. Turf establishment and erosion control measures must be implemented immediately following grade approval. The TRE pit location is available for excavation for up to 24 months after plan approval, after which the excavation area may be reassigned to another development.
