Stormwater Management Design
JNM Engineering prepares customized stormwater management plans with construction specifications and maintenance schedules. Our designs range from small-scale practices to regional ponds, ensuring compliance with environmental regulations. We utilize advanced modeling tools to optimize runoff control and pollutant reduction.
Environmental Site Design
We implement low-impact development techniques to minimize post-construction runoff. Our ESD solutions integrate planning strategies and green infrastructure, aligning with Maryland's regulatory requirements while preserving natural site features and reducing long-term maintenance costs.
Natural Resource Inventories
Our specialists identify wetlands, streams, forests, and critical habitats to inform site design. Inventories prioritize environmental features early in planning, ensuring compliance with state and federal regulations while optimizing land use efficiency and conservation outcomes.
Arborist Reports
Certified arborists evaluate tree health and structural integrity for development projects. Reports include preservation recommendations, retention potential, and maintenance strategies to prevent construction-related tree decline while meeting regulatory requirements for protected species.
Floodplain Studies
We identify unrecorded floodplain areas through detailed hydrological analysis. Our studies include regulatory reports and mitigation plans to address development constraints, ensuring compliance with local agencies and reducing potential construction risks and costs.
