Mindy Chassin Horowitz, PG, WEDG

Ms. Horowitz is a registered Professional Geologist with over thirty years of experience in the environmental consulting field, performing hazardous materials assessments, waterfront permitting, construction oversight, and remedial design. She has been a Principal Geologist with Roux since 2025. Ms. Horowitz’s areas of expertise include public infrastructure projects; brownfield cleanup and redevelopment; investigation and remediation of New York City E-designation sites with potential hazardous material contamination; environmental due diligence of industrial, commercial, residential, and mixed-use facilities; and environmental corridor studies to support CEQR/SEQRA/NEPA EAS/EIS preparation. She has extensive experience managing and conducting hydrogeologic investigations for clients in both the public and private sectors, including projects focusing on railroads, highways, airports, and educational, industrial, and commercial facilities. Her combined hydrogeological and geo-environmental engineering background, along with her varied experience, enable her to compile and interpret analytical data to develop clear and technically defensible conceptual site models.

Mindy is a Waterfront Edge Design Guidelines (WEDG) Associate, an Office of Environmental Remediation (OER) Certified Brownfield Professional, and serves on the board of the New York City Brownfields Partnership.

• Project Director, Gateway Development Corporation Manhattan Shaft Design Build, New York, New York. Provided environmental management and compliance, sustainability, land surveying, stormwater construction management, construction inspections, and landscape architecture on the project. The Manhattan Tunnel Project will build a section of the new Hudson Tunnel Project tubes, connecting to the Hudson Yards Concrete Casing. The project also includes designing and building an access shaft at 12th Avenue. The shaft will be used to remove the tunnel-boring machines that built the portion of the tunnel under the Hudson River, and then will be converted into a permanent ventilation facility for the new tunnel. As Director, Mindy provided contract management, QA/QC reviews of documents, environmental compliance training, and general oversight of the various disciplines working on the project.
• Project Manager, Battery Park City North and West Resiliency Project, New York, New York. Project Manager on the Consulting Engineer team to support the Battery Park City Authority’s (BPCA) coastal resiliency and flood protection plans. The BPCA is undertaking the creation of an integrated coastal flood risk management system, known as the Combined North and West PDB Project. The flood mitigation system will begin at First Place, run north along the Battery Park City Esplanade, across to the east side of West Street/Route 9A, and terminate above Chambers Street at a high point on Greenwich Street. Ms. Horowitz worked with the consulting engineering team to develop background technical information; perform geotechnical investigations, topographic, utility, and sewer surveys; perform environmental and hazardous materials surveys; and perform regulatory permitting. Ms. Horowitz also prepared technical requirements to be included in the Design-Build request for proposal (RFP), and contracted and prepared relevant chapters of the Environmental Impact Statement (EIS). Mindy allocated resources, acted as client liaison, coordinated engineering technical deliverables, and performed quality assessment/quality control (QA/QC). She also participated in regular project meetings and provided updates to the design team and the BPCA.
• Environmental Project Manager, NYCEDC/NYC Parks Box Street Park, Brooklyn, New York. Environmental Project Manager for this project on Newtown Creek, where a former Metropolitan Transit Authority (MTA) maintenance facility is being converted to a New York City Park. Ms. Horowitz oversaw the preparation of a Remedial Action Work Plan (RAWP), which was approved by the New York State Economic Development Council (NYSEDC). The RAWP addressed known hazardous metals contamination, petroleum contamination, and underground storage tank removal. The project involved the removal of a bulkhead wall and the design of a riprap slope, with excavation landward to accommodate the redesign. The removal of the bulkhead triggered the requirement for a Sediment Sampling Plan to sample sediment and seeps potentially disturbed from the Newtown Creek bed. Ms. Horowitz worked with NYCEDC and NYC Parks to develop the plans and negotiate with New York State Department of Environmental Conservation (NYSDEC).
• Environmental Project Manager, NYCEDC Tompkinsville Esplanade and Pier Project, Staten Island, New York. Environmental Project Manager for the National Environmental Policy Act (NEPA) environmental assessment (EA) for the NYSEDC to support the creation of a new waterfront esplanade and pier within the Tompkinsville section of Staten Island. In support of this project, Ms. Horowitz supported environmental reviews to satisfy the requirements of National Environmental Protection Act (NEPA) in accordance with the Federal Emergency Management Agency’s (FEMA) regulations for NEPA implementation, the New State Environmental Quality Review Act (SEQR), and the New York City Environmental Quality Review (CEQR). The objective of this project was to create a walkable waterfront recreation area, clean up damage remaining from Superstorm Sandy, and construct a new pier to house New York City Department of Transportation dock building operations. Ms. Horowitz performed a Phase I Environmental Site Assessment and subsequent environmental investigations along the project area, including the collection of soil and groundwater samples. The findings were incorporated into the hazardous materials chapter of the EA. Ms. Horowitz also prepared a Remedial Action Plan and Construction Health and Safety Plan.
• Environmental Project Manager, PANYNJ LaGuardia Airport Access Improvement Project, Corona, New York. Ms. Horowitz was responsible for the environmental program for the Port Authority of New York and New Jersey (PANYNJ) to support preparation of an Environmental Impact Statement (EIS) to comply with the provisions of the NEPA, with the Federal Aviation Administration (FAA) as the lead federal agency for the project. The project included the construction of a new automated people mover (APM) system for improved access to LaGuardia Airport through connections to the Long Island Rail Road (LIRR) and New York City Transit (NYCT). She oversaw a Phase I ESA for the entire corridor, extending from the airport to the Willets Point Station. She also oversaw the preparation of Phase I ESAs for multiple multi-lot properties in Corona, Queens, New York. The findings of the Phase I ESAs were used to develop a sampling plan for a Phase II Environmental Site Investigation (ESI), which included the installation of soil borings and temporary well points, collecting soil and groundwater samples to characterize materials encountered during construction. The results of the investigation were used to develop the Affected Environment and Environmental Impacts sections of the Hazardous Materials chapter of the EIS. Ms. Horowitz also participated in public outreach, acting as a subject matter expert on the public workshops, responding to public comments on the project.
