Chevy Chase Lake is a mixed-use community center located along Connecticut Avenue in Chevy Chase, Maryland. The development is designed as a walkable, transit-oriented destination and includes residential, retail, and public gathering spaces organized around a central town square. Now largely complete and operational, the project features hundreds of residential units, approximately 100,000 SF of retail space, landscaped open areas, and structured parking. The development is situated within a dense, mixed-use corridor and is planned to be served by the future Purple Line light rail system, further enhancing regional connectivity.

Hillis-Carnes provided Environmental Consulting Services for Block B (Phase I), which consists of three buildings. Building B1 is an 11-story residential structure with ground-floor retail and a two-story below-grade concrete parking garage. Building B2 is a six-story mixed-use building with ground-floor retail and 65 condominium units. Building B3 is a six-story mixed-use building with ground-floor retail and 279 residential apartments.

Hillis-Carnes was contracted to provide Environmental Professional (EP) Services for Building B1. Services included environmental monitoring during excavation, dust control, soil characterization of both uncontaminated and non-hazardous contaminated materials, monitoring and testing of dewatering system discharge, and quality assurance and quality control. Hillis-Carnes also performed a Phase I Environmental Site Assessment (ESA), which included site and area reconnaissance, a regulatory database review, a historical records search, and interviews.

For Buildings B2 and B3, Hillis-Carnes provided Environmental Consulting Services with a similar scope, including environmental monitoring during excavation, dust control, soil characterization, dewatering discharge monitoring and testing, and QA/QC. Additional services included project preparation, sampling of suspect asbestos duct bank materials, sub-slab soil sampling, and environmental monitoring during vapor barrier installation. Phase I Environmental Site Assessments were also completed for both buildings, including site and area reconnaissance, regulatory database review, historical research, and interviews.

Hillis-Carnes also prepared an Environmental Management Plan (EMP) for Block B on behalf of Bozzuto Associates. The EMP was developed to support redevelopment activities by establishing procedures for identifying, testing, handling, and disposing of contaminated soil and groundwater encountered during construction. Implementation of the plan helped ensure that impacted materials were managed in a manner protective of human health and the environment, while also limiting owner liability and maintaining compliance with applicable federal, state, and local regulations.

In addition to environmental services, Hillis-Carnes provided geotechnical engineering and construction materials testing and inspection services throughout the project.
