Four Corner - Texas Water Development Board

permanent rules, Chapter 290 (Water Hygiene). Sanitary sewer collection and treatment
systems must be designed in accordance with TNRCC permanent rules, Chapter 317
(Design Criteria for Sewage Systems). The Four Corners planning area lies within the
Extra-Territorial Jurisdiction of the City of Houston. In addition to the requirements of
TNRCC, water and sanitary sewer facilities must be designed in accordance with the
September 1996 "Design Manual for Wastewater Collection Systems, Water Lines,
Storm Drainage and Street Paving" issued by the City of Houston Department of Public
Works and Engineering. City of Houston design requirements are more stringent than
TNRCC with respect to certain design elements of water and wastewater systems.
Construction drawings for water and sanitary sewer facilities must be approved and
signed by the City of Houston prior to the initiation of construction.
C. Right-Of-Way Requirements - The proposed trunk water and sanitary sewer
facilities to serve the Four Corners area will be constructed along the major roadways of
Boss-Gaston/Old Richmond Road and Richmond-Gaines Road. Right-of-way widths
along these roadways vary in width from 50 to 70 feet. No additional right-of-way
acquisition would be anticipated. However, field visits have found evidence of gas,
electric and telephone utilities along both roadways. Exact locations of these facilities
will be necessary in final design and may dictate the location of the proposed water and
sewer facilities relative to the existing roadway/drainage and utilities. To provide for a
looped connection of the water system east of Richmond-Gaines Road, acquisition of a
water line easement along the east side of the Atanacia Martinez subdivision from Old
Richmond Road south to Dora Lane will be required.
Lift station and pump station sites have been preliminarily located along Boss-Gaston
Road and Richmond-Gaines Road as shown on the sanitary sewer system layout in the
Appendices. These locations include some flexibility in terms of their physical location
on each roadway but acquisition of each site will be necessary as each proposed station
is included in the final design.
