Childs Engineering conducted a hydrographic survey on behalf of Green International Affiliates for the MassDOT-owned McArdle Bridge over Chelsea Creek. The scope of work included a detailed single-beam bathymetric survey of a 4-acre section of the waterway, both upstream and downstream of the bridge.

The primary objectives of the survey included identifying and mapping several submerged objects located adjacent to the bridge piers, as well as establishing the position of the Mean Low Water (MLW) elevation throughout the surveyed area. This data was critical for supporting ongoing engineering evaluations and ensuring navigational safety in the vicinity of the bridge structure. All survey operations adhered to standard hydrographic procedures and were coordinated to minimize disruption to waterway traffic.
