About this file
This is an engineering design document from the Harris County Engineering Department for a drainage improvement project in the Brays Subdivision. The technical drawing depicts a proposed typical road cross-section with detailed specifications for road construction, including a 60' right-of-way, 6" concrete curb, and a stabilized subgrade prepared with lime. The drawing includes precise measurements for water and electrical service relocations, subgrade preparation, and road grading across multiple drive sections such as Advance Drive, Beachil Drive, Chatham Drive, and Amado Drive, with station points ranging from 24+00 to 31+00.
The document appears to be part of a 2018 drainage mitigation project, with specific engineering requirements for soil composition, including a 6" minimum stabilized subgrade prepared with lime and compacted to achieve a maximum dry density with an optimal moisture content per geotechnical recommendations. The design includes detailed utility relocations for 1" water and electrical services, longitudinal steel reinforcement, and precise grading specifications. The project is being executed by Brooks & Sparks Inc. as the engineering contractor, with clear technical specifications for road construction and drainage improvements.
