Stormwater Management Design, Construction, Maintenance, and Inspection.
JNM brings unparalleled experience in crafting comprehensive stormwater management plans and reports. Our designs encompass detailed plans and reports, construction specifications, design details, operation and maintenance schedules, and material specifications. With a diverse portfolio ranging from small-scale stormwater solutions to expansive regional ponds, we ensure effective & sustainable practices. Additionally, our sister company, A1 Stormwater Management, provides turn-key construction services for a seamless experience. Discover more by visiting A1 Stormwater Management.
Floodplain Studies
At JNM, we understand challenges posed by unidentified floodplain areas along Maryland waterways. These hidden floodplains can not only hinder development but also lead to unexpected construction costs. Our team specializes in identifying and delineating unrecorded floodplain areas early in the design process, ensuring a smoother project trajectory. We provide comprehensive reports, computations, and plans to help you secure the necessary approvals from local regulatory agencies.
Stormwater Management Inspections
JNM recognizes the vital role of storm management in our communities. Our expertly designed, constructed, and maintained stormwater management systems effectively minimize pollutants and sediment from entering our waterways, aquifers, and the Chesapeake Bay. We design to ensure these systems operate at peak efficiency, helping you avoid local state violations and expensive repairs. Should issues arise, our team, along with A1 Stormwater Management, is ready to collaborate with regulatory agencies to restore compliance and function. To set us apart and to ensure we are providing the maximum level of service, all inspections are certified by a Licensed Professional Engineer.
Environmental Site Design
Environmental Site Design (ESD) is now required for most land disturbance activities in Maryland. Other variations of ESD are sometimes called better site design, low impact development (LID), green infrastructure, or sustainable site design. All of these strategies include similar techniques to reduce post-development runoff impacts. In each, a combination of planning techniques, alternative cover, and small scale treatment practices are used to address impacts associated with land development. JNM consists of highly experienced stormwater management engineers that have extensive knowledge of ESD design, oversight and review, and application.
Natural Resource Inventories
At JNM, our team of environmental professionals is dedicated to conducting comprehensive and complete natural resources inventories. These inventories are essential for identifying and prioritizing natural resources before site design begins. Our studies typically encompass the identification of wetland areas, stream locations, environmental buffers, forested regions, soil types, steep slopes, critical areas, floodplains, and other site significant features. Proper delineation of these natural resources is a vital step in the development process ensuring sustainable and responsible planning.
Forest Stand Delineation and Forest Conservation
At JNM, our team of highly trained DNR qualified professionals and environmental specialists is dedicated to preparing comprehensive natural resource inventories and forest conservation plans. Our Forest Stand Delineations provide detailed insights, including forest boundaries, soil types, and environmental areas, all combined with a thorough forest stand narrative. We expertly develop Forest Conservation Plans to identify which forest areas should be retained or planted, ensuring compliance with the Maryland Forest Conservation Act. By collaborating with our clients early in the development process, help create better site designs that minimize planting needs and reduce stormwater management requirements.
Arborist Report and Tree Preservation Recommendations
Our highly trained ISA certified arborists can provide tree health evaluations and tree protection recommendations for your development projects. Arborist evaluations are critical for many infill type developments where construction will occur close to existing trees. Tree death, decline, and structure failure can occur months or even years after construction practices have ended if appropriate tree protection and monitoring measures are not implemented. Many tree related problems can be avoided if an arborist is consulted early in the design process. JNM can prepare detailed tree assessments. These assessments typically include tree identification, a health assessment, measurements, preservation recommendations, retention potential, and maintenance recommendations. All reports are prepared and signed by a certified arborist.
Civil Construction Plans and CAD Drafting
Construction plans are required for most development projects. JNM can prepare professionally drafted and certified construction plans to detail your site development needs. Our drafting services range from minor tree protection exhibits to full development plans.
Drainage Solutions
Recent changes to local rainfall intensities has created drainage problems for many homeowners in Montgomery County and surrounding jurisdictions. Higher intensity storms has led to more erosion, wet basements, flooding, and property damage. JNM Engineering offers site inspections and can provide fully engineered drainage plans to mitigate your drainage concerns. Our reports provide the necessary flow computations and an engineered drainage study custom to your property and situation. See Stormwater tax credit below.
​
Stormwater Tax Credits - RainScapes
Many jurisdictions now offer incentives, reimbursements, and tax credits for homeowners who provide mitigation for their stormwater runoff. An example is Montgomery Counties RainScapes program which will reimburse homeowners up to $2,500.00 for the installation of stormwater management devices. If you have a drainage problems on your property, this may be a perfect opportunity to take advantage of these programs. Click here to to find out more about Montgomery Counties program.
Green Area Ratio (GAR) Plans (District of Columbia)
GAR is a standard requirement for many development projects within the District of Columbia. JNM Engineering can provide the required plans and evaluation to address GAR requirements through the Department of Energy and Environment.
