City of Norton – Upper Norton Dam and Spillway Improvements

City of Norton – Upper Norton Dam and Spillway Improvements

The City of Norton owns and operates two impoundments for water supply purposes, one situated above the other on Benges Branch, to the south and above the downtown area. The upper dam was completed in 1959 and modified in 1997. The reservoir is a 73 foot deep earthen structure with a maximum capacity of 202 acre-feet. Regulations require that the reservoir be capable of safely passing the Probable Maximum Flood (PMF). The City of Norton partnered with T&L to plan, design, permit and construct improvements to the Upper Norton Dam and spillway.

A summary of T&L’s services includes:

• Preparation of a Preliminary Engineering Report (PER) to evaluate alternative solutions for improvements to the existing impoundment;
• Evaluation of the existing spillway capacity;

The PER recommended that an auxiliary spillway be constructed to increase capacity for passage of the PMF. To retain the same pool elevation and provide an adequate channel for the spillway, a labyrinth spillway (shaped like a “zigzag”) was utilized due to space considerations.

Major design and construction elements included:

• A 50-foot wide reinforced concrete auxiliary spillway chute with energy dissipation at the outlet;
• Structural concrete chute walls to contain spillway flows; and
• A labyrinth weir at the inlet of the spillway.

This project was completed in 2013, with a construction cost of approximately $2,232,000.

Town of Bedford Stoney Creek Dam

T&L was retained by the Town of Bedford (formerly City of Bedford) to investigate and make recommendations regarding spillway and other repairs to the Stoney Creek Dam. Following the development of a Flood Inundation Study, Preliminary Engineering Report, and Geotechnical Analysis, it was determined that certain improvements to the Dam were required.

These improvements included:

• Repairs on the existing Dam spillway; and
• Construction of an auxiliary spillway to increase capacity

These improvements were addressed by the design and construction of several improvements which involved:

• Structural repairs to the concrete chute spillway;
• Structural concrete chute walls to contain spillway flows; and
• A roller compacted concrete auxiliary spillway to bring the total spillway capacity up to the probable maximum flood flow requirements.
