Having outgrown its original 1961 Town Hall and addition, the Town of Orangetown selected Lothrop Associates and their team of consultants to design a new multi-story, 35,000 square foot addition that consolidates and improves services in one location (Municipal Offices, Police Headquarters, and Municipal Court). Once construction of the new addition is largely complete, the original 1961 structure will be demolished and the parking field expanded to support over 250 vehicles. As part of the design team, Tectonic provided geotechnical engineering, environmental consulting, hazardous materials, and site/civil engineering roles. Services included:

Geotechnical Investigation: Performed a program of 9 test borings (drilling, sampling, observation, and logging),
evaluation of the encountered subsurface conditions, and reporting for the new addition. Recommendations included shallow spread and continuous wall footings for the building and a preliminary design was provided for a geosynthetic-reinforced soil retaining wall.

Environmental Documentation:

• SEQRA included the preparation of a Environmental Assessment which included Parts 1, 2 and a Traffic Study under Part 3, to assess the traffic impact of the project on the adjacent roadway network. A Negative Declaration was completed for lead agency adoption.
• SHPO review was conducted to determine no properties, including archaeological and/or historic resources, listed in or eligible for the New York State and National Registers of Historic Places would be impacted by the
  project.
• Threatened and Endangered species survey and report preparation was completed to determine potential impacts of the proposed project on any state or federally designated rare, threatened, or endangered species.

Hazardous Materials:

• Preliminary Soil Waste Characterization was provided for subsurface soils within proposed areas of excavation including field screening of soils with a PID, soil sampling from borings advanced as part of a concurrent geotechnical investigation, standard chain-of-custody protocol, interpretation of analytical results, and a Field Sampling Summary Report.
• Performed a limited hazardous materials (HAZMAT) survey, bulk sampling, and report for lead-based paint, asbestos (NYSDOL-certified asbestos inspector), and potentially PCB-containing materials in all areas to be disturbed during scheduled demolition and renovation activities.
• Based on the results of the preliminary waste characterization services and HAZMAT surveys, Tectonic prepared project specifications for soil management, lead paint management, PCB material removal and asbestos abatement.

Site/Civil: Redesigned the existing site to accommodate the new facility, expanded parking, new water/sewer services, and new circulation patterns. Intricate planning of the project phasing was required to maintain existing operations and access during construction. The project also employed green infrastructure through rainwater harvesting for the new irrigation system. A detailed stormwater pollution prevention plan was developed for implementation during construction.
