North Canal Diversion HCFCD Project

On-going surveying for property acquisition and engineering design surveys of re-routing of Buffalo Bayou north of downtown Houston between North Main Street and McKee Street. Services to be provided include “soundings” for Buffalo and White Oak Bayous.

Northpark Drive Mobility Project

EHRA completed preliminary engineering, phase one environmental site assessment and schematic development for the widening of Northpark Dr. between US 59 and Woodland Hills Dr. EHRA also provided program management, drainage analysis and design, traffic engineering, environmental documentation and schematic design for the roadway, as well as grade separation at the Loop 494/UPRR railroad crossing.

EHRA conducted traffic operations and access management studies for the Northpark Dr. corridor. This corridor is approximately 2.2 miles long and has major signalized and unsignalized intersections and driveways that access various subdivisions and industrial developments. These studies laid the groundwork for the widening of Northpark Dr. from a four-lane boulevard cross-section to a six-lane boulevard complete street. The new street design includes low impact development drainage, conventional drainage, a grade separation at the UPRR crossing with mechanically stabilized earth retaining walls, two at-grade crossings for bi-directional frontage access, reconstruction of two concrete bridges over a diversion channel, intersection improvements, a roadway-adjacent multiuse path and traffic signal improvements.

Drainage analysis and design included hydrologic and hydraulic studies of both existing and proposed conditions to demonstrate that proposed project components would not adversely affect the 100-year floodplain in the area. The roadway and traffic designs contained horizontal and vertical alignments, cross-sections, plan and profile, sidewalk and bicycle accommodations, intersection layouts, traffic control plans and signing and pavement markings.

As the program management firm, EHRA coordinated with TxDOT, UPRR, the City of Houston Council District E, COH Planning and Development Department, COH Public Works and Engineering Department, Montgomery County, Harris County, HCFCD and area residents throughout the project.

Cane Island Parkway

The new roadway design comprises of one-half major thoroughfare, conventional drainage, a 600-ft long bridge over Willow Fork Bayou, Retaining walls and intersection improvements at FM 1463 (including traffic signals and illumination).

Harris County MUD 449 Wastewater Treatment Plant Expansion

Facilities requiring expansion were also common wall construction, and the EHRA team converted the facilities into aerobic digesters and sludge thickeners.

Water Crest Development

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.

Construction Pricing Update

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.

Water Trends

8" PVC Waterline costs have continued to trend downward from the peak pricing near the end of 2023.

PVC Watermain-2

Sanitary Trends

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

Sanitary Sewer-2

Drainage Trends

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

RCP Storm Sewer-2

Paving Trends

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.
