Mueschke Road Environmental Assessment for Park and Maintenance Facility, Harris County Engineering Department, Precinct 3, Harris County, Texas

Project Description

R.G. Miller Engineers, Inc. (RGME) was retained by Harris County Engineering Department (HCED) to perform a wetland assessment, delineation and ordinary high water mark (OHWM) study on approximately 90 acres of land located in Harris County, Texas. Harris County Precinct 3 and Harris County Flood Control District propose to develop the Mueschke Road Park and Maintenance Facility and a flood damage reduction facility on the tract.

The purpose of the investigation was to identify, classify, and document the location and extent of all potential WOUS including waterbodies and wetlands, within the proposed project area through the delineation of the boundary of such features. The OHWM of any features in the project vicinity was also defined to establish the extent of waterbodies such as streams, channels and ponds. As part of this investigation, determinations were made whether these features are considered potential WOUS, as defined by Section 404 of the CWA and/or Section 10 of the RHA, subject to the jurisdiction of the USACE Galveston District and USEPA.  This information was obtained through both desktop and field investigations.

Delineation field work was completed in January 2018. Five wetland areas were found ranging in size from 0.03 acres to 7.31 acres. Three were found to be jurisdictional due to their proximity to a tributary of a traditionally navigable water.  USACE verification was accomplished in March 2018.
