EHRA performed preliminary drainage area delineations for nine creek crossings and calculated approximate 100-year flows for each culvert crossing. Culvert structures were sized for each of the six crossings, ranging from 48” round pipe culverts up to dual 5’x5’ box culverts.
A 720-acre gated master planned community located off Telge Road, just north of Willow Creek. See how EHRA was involved in this project.
In 2006, Caldwell Companies sought to create Towne Lake as a community where residents and services could be connected by water. Their vision included boat docks and marinas augmenting traditional walking trails to navigate a vibrant residential community. EHRA was the perfect partner to take Caldwell Companies’ vision and create this livable suburban oasis.
EHRA assisted with the district creation of Montgomery County Municipal Utility District No. 126 to accommodate a ±329 acre master planned community located in northern Montgomery County in the City of Conroe, south of League Line Road, west of Longmire Road, and adjacent to Lake Conroe.
The purpose of this project was to convert the existing at-grade crossing of Brazoria County Road 56 (CR 56) and State Highway 288 (SH 288) into a diamond interchange that includes a new overpass bridge. Coordination with TXDOT, area landowners, utility companies, and Brazoria County was integral in obtaining approval and acceptance of the project.
Construction Costs Lowest in 5 Years!
After several years of unprecedented escalation, construction pricing for land development infrastructure is showing meaningful signs of stabilization. EHRA's Construction Services team has analyzed construction bid results from projects across the Greater Houston area and many key infrastructure components have reached their lowest average pricing levels in the past five years.
While pricing remains above pre-2020 levels, increased contractor competition and improved material availability and a more balanced market has led to the recent favorable bidding conditions throughout much of the region.
This result could be a welcomed shift for developers, municipalities and utility districts seeking to maximize project budgets and advance capital improvement programs.
In the charts below, we highlight four key construction cost indicators that serve as benchmarks for many public infrastructure and land development projects: 8-inch waterline, 8-inch sanitary sewer, 24-inch storm sewer and 6-inch pavement. These trends provide valuable insight into current market conditions and can help inform planning, budgeting and project timing decisions.
Let's take a closer look at the numbers.
8" PVC Waterline costs have continued to trend downward from the peak pricing near the end of 2023.

8” PVC Sanitary sewer have continued to trend downward from the peak pricing near the end of 2023.

24” RCP Storm Drainage Pipe Cost have continued to trend downward from the peak pricing near the end of 2023.

6” Concrete Paving cost have continued to trend downward from the peak pricing near the end of 2023.

Although market conditions can change quickly, current trends indicate a favorable environment for moving projects forward. EHRA will continue monitoring construction pricing across the region and sharing updates to help our clients make informed planning and budgeting decisions.
