See our projects to discover what SESI can do for you. We offer a wide range of site remediation services in New Jersey, including Stormwater and Watershed Management, Special Hydraulic and Groundwater Modeling, Dam Rehabilitation and Design, Regulatory Approvals and Land Use Entitlements, Site Designs, Plans, and Specifications.
What is Site/Civil Engineering?
Site/Civil engineering combines knowledge of a property’s environmental constraints, project impact, and relevant regulations to determine a development’s feasibility. A site layout is developed while liaising with stakeholders, consultants, contractors, and relevant government agencies. Environmental constraints include soil characteristics, location within a watershed, and hydrologic considerations. Project impact includes zoning and land use ordinance effects, impervious surfaces, stormwater runoff water quality, and topographical changes, such as the need for retaining walls due to significant elevation changes. Government agencies include local, state, and federal agencies like the Environmental Protection Agency (EPA), Army Corps of Engineers (USACOE), New Jersey Department of Environmental Protection (NJDEP).
During a major precipitation event, such as rain or snow, infrastructures can be overwhelmed by both the volume and intensity of runoff into natural and/or manmade waterways. The stormwater management design accounts for several factors to create a reduction in runoff volume, rate, and pollutant concentration into public streams.
Watersheds are regionally and topographically-connected areas where runoff moves prior to being deposited into a body of water that can cross municipal, county, and state boundaries. The engineer evaluates geological/hydrogeological maps and then takes development, and adjacent/local area activity, into account to ensure that the impacts of the project on the watershed are mitigated.
Special Hydraulic Modeling
This application of fluid mechanics allows for the design of stormwater systems utilizing unsteady (time-dependent) modeling. This type of modeling is employed in sizing pumps in a system, as well as in riverine floodplain analysis. Results from this type of modeling determines the design of spillways and outlet works for dams, erosion and flood protection, water quality treatment device sizing, and other important features to address environmental site impacts.
Dams are utilized across New Jersey to assist with flooding control, irrigation, hydropower, etc. However, natural aging, lack of resources, natural and man-made threats can negatively impact dam infrastructure. Rehabilitation allows an engineer to support an existing dam and ensure continued safety and effectiveness.
Dam design is impacted by the type of property, intended land use, and client's needs. We closely consider all environmental factors that will impact the structure and function of a dam. While also following state and local guidelines to keep the public safe.
Groundwater Mounding Analysis
Groundwater mounding analysis allows geotechnical engineers to evaluate the impact of stormwater runoff. Several tests are performed on the infiltration basin to determine if it will “mound up.” The analysis will determine if below-ground structures need to be altered to accommodate an overflow of water.
This study occurs early in the development plan. The site/civil engineer takes knowledge of a property’s environmental constraints, project impact, and relevant regulations to determine a development’s feasibility. A site layout is developed while liaising with stakeholders, consultants, contractors, and relevant government agencies, and then presented to the Client.
Site Designs, Plans & Specifications
Using information available from historical data, environmental, topographic, and land use mapping, the site/civil engineer will design a development project taking appropriate physical or legal restrictions into account. We point out that throughput this process the site/civil engineer is constantly in communication with the Client to ensure that the resulting project is in line with his or her Vision.
Regulatory Approvals & Land Use Entitlements
The state can require regulatory approvals and land use entitlements depending on your development project. SESI civil consulting engineers make the NJ approvals and entitlement processes quick and easy. Ensuring your project stays on budget and time frame is SESI`s top priority.
