Client: Northwestern Oregon Development Team
Project Type: Conversion and Redevelopment of Pre-1940 Motel into Permanent Supportive Housing
Project Timeline: 24 months during the design and application phase
Funding Sources: HUD – Project-Based Vouchers (PBV), Oregon Housing and Community Services LIHTC, Various state and local soft funds
D3G was engaged to provide environmental consulting services for the conversion and redevelopment of a pre-1940 motel and its associated buildings into a Permanent Supportive Housing (PSH) development. The project, located in Northwestern Oregon, involved early consultations and extensive collaboration to ensure compliance with HUD regulations and local environmental requirements. Given the sensitive nature of the project, bi-weekly calls and consistent communication were crucial to maintaining progress within the proposed timeline.
D3G was brought on board as the environmental consulting partner to guide the redevelopment team through the environmental review process, ensuring all project activities complied with HUD’s requirements and local municipal standards. Our team provided ongoing support, led critical assessments, and facilitated collaboration between the development team, HUD, and the Responsible Entity (RE).
The project required careful planning and coordination to meet HUD’s stringent Environmental Review requirements, including floodplain management and the mitigation of hazardous materials like asbestos and lead-based paint. Additionally, the project site’s proximity to an adjoining fuel storage tank raised concerns due to HUD’s Acceptable Separation Distance (ASD) calculations, which necessitated the development of specific mitigation measures.
Early Consultation and Compliance Alignment: D3G began by confirming the Responsible Entity (RE) and aligning the Environmental Review reporting process with HUD’s prescribed format (HEROS vs. traditional). A meet-and-greet discussion between D3G, the development team, and the RE set the foundation for compliance and smooth project execution.
Floodplain Documentation Review: To expedite the site plan development and municipal approval processes, D3G reviewed FEMA and HUD floodplain documentation, identifying the necessary lowest floor elevations to ensure compliance with floodplain management standards. D3G assisted the RE with HUD’s 8-Step Process in accordance with 24 CFR Part 55 and Executive Order 11988, publishing public notices and working closely with the project team.
Civil Site Plan Review: D3G reviewed the civil site plans to ensure that both onsite and offsite activities were considered and compliant with HUD’s project aggregation requirements. This early involvement allowed the development team to remain ahead of local approval processes.
Fuel Storage Tank Mitigation: D3G worked with a Professional Engineer engaged to assess an adjoining fuel storage tank that failed HUD’s ASD calculations. The team developed sufficient mitigation in accordance with 24 CFR Part 51, Subpart C, ensuring the safety and environmental compliance of the project.
Noise Assessment and Mitigation: In line with 24 CFR Part 51 Subpart B, D3G conducted a noise assessment using HUD’s Day/Night Noise Level (DNL) Electronic Assessment Tool. This was followed by Sound Transmission Class (STC) calculations using HUD’s Sound Transmission Classification Assessment Tool (STraCAT). D3G also provided barrier attenuation calculations to address elevated external noise levels.
Hazardous Materials Management: Prior to the demolition and rehabilitation, D3G coordinated and reviewed hazardous materials reports concerning asbestos-contained materials (ACMs), lead-based paint (LBP), and radon gas. D3G consulted on mitigation design to ensure compliance with environmental and health standards.
Environmental Assessments: D3G conducted a Phase I Environmental Site Assessment (ESA) and a subsequent regulatory file review to ensure the project’s compliance with HUD’s contamination and toxic substance policies (24 CFR Part 50.3(i) and 24 CFR 58.5(i)(2)). As part of the NEPA process, D3G prepared, submitted, and tracked all necessary agency consultation packages, facilitating seamless communication between all parties involved.
Endangered Species Act and Regional Compliance: Given unique HUD regional requirements, D3G played a critical role in coordinating efforts with the US Fish and Wildlife Service, National Marine Fisheries Service, and the RE to ensure project plans were compliant with the Endangered Species Act and the Magnuson-Stevens Fishery Conservation and Management Act.
HEROS Processing: D3G processed the Environmental Assessment (EA) in HEROS, coordinating with the RE and leading to a Finding of No Significant Impact (FONSI) determination.
D3G was involved for nearly 24 months during the design and application phase, providing critical environmental consulting services from inception through completion.
15 members of D3G’s environmental and account management team were involved in the project. Subject Matter Experts, including D3G’s Principal Geologist, provided essential support in contamination reviews, noise studies, hazardous material management, and ongoing consultation throughout the project. The team’s involvement in bi-weekly discussions ensured the project remained on track, meeting the required compliance milestones within the set deadlines.
D3G’s extensive environmental expertise and hands-on approach were instrumental in the successful conversion of a pre-1940 motel into Permanent Supportive Housing in Northwestern Oregon. By aligning the project with HUD’s strict regulations, managing environmental risks, and providing consistent support, D3G facilitated a smooth and compliant redevelopment process that will serve the community for years to come.
