Practical Civil Engineering That Gets Projects Approved

Civil engineering covers the design of systems that work with the land — drainage, grading, site layout, soils, and infrastructure. At NEC Solutions LLC, our civil engineering services are focused on the practical needs of homeowners, contractors, developers, and municipalities in Pennsylvania, New York, Delaware, and Texas.

We don't just prepare drawings — we solve real problems. When your site needs a stormwater management plan for a land development approval, we design a system that works within the site constraints and satisfies the municipal engineer. When you need soil testing for a new septic system, we coordinate the perc test, evaluate the results, and deliver the documentation the health department requires. When a proposed grading plan needs drainage analysis, we run the hydrology and make sure the numbers work.

Our civil engineering team works closely with our structural engineers, which means we can handle projects that span both disciplines — a combination that saves our clients time and coordination headaches. Whether your project is a single-family home site, a commercial development, or an industrial facility, we bring the same focused, practical approach to every civil engineering scope.

What We Do

Our Civil Engineering Service Areas

Stormwater Management

Pennsylvania and Delaware require stormwater management plans for most land development and redevelopment projects. We design cost-effective BMP systems that meet state and municipal requirements and get approval from the municipal engineer.

Stormwater management plans (SWMPs)
Pre- and post-development hydrology analysis
Detention basin and infiltration basin design
Bioretention (rain garden) design
Underground infiltration system design
PA DEP NPDES permit support drawings
Grading & Site Plans

New construction sites, additions, and land development projects typically require grading plans showing how the finished site will drain. We prepare grading and drainage plans for permit submission to municipalities, townships, and county engineering offices.

Existing and proposed grading plans
Erosion and sediment control (E&S) plans
Site drainage design and outlet protection
Driveway and access design
Impervious coverage calculations
Land development plan support drawings
Geotechnical Investigations

Understanding what's in the ground is essential for foundation design, retaining wall engineering, and site development. We coordinate and perform geotechnical investigations that provide the soil data your project needs — borings, test pits, and laboratory testing.

Soil borings and test pit investigations
Standard Penetration Test (SPT) boring
Soil bearing capacity analysis
Geotechnical report preparation
Foundation recommendation reports
Settlement and liquefaction analysis
Soil Testing for Septic Systems

In rural and suburban areas of PA and DE, new homes and properties without municipal sewer require a septic system — and a perc test and soil evaluation to prove the site can support one. We perform or coordinate the soil testing required for septic system permitting.

Percolation (perc) test coordination
Soil profile evaluation
Limiting zone determination
Sewage module support documentation
PA DEP Chapter 73 compliance
Septic system feasibility reports
Site Development Engineering

Commercial and residential site development requires civil engineering coordination from concept through permit approval. We work with developers, architects, and landowners to prepare the civil engineering components of land development submissions.

Preliminary and final land development plans
Utility layout and coordination
Parking lot layout and drainage
ADA compliance review for site work
Zoning and setback compliance support
Subdivision plan support drawings
Civil Engineering Reports & Studies

Beyond design drawings, civil engineering projects often require written reports, feasibility studies, and technical analyses for regulatory submissions, zoning hearings, and project planning. We prepare the civil engineering reports your project requires.

Drainage feasibility studies
Stormwater impact assessments
Floodplain analysis and FEMA compliance
Traffic and site circulation review
Environmental impact support documentation
Expert engineering report preparation

Spotlight Service

Soil Testing for Septic Systems in Pennsylvania

If you're building a new home or adding a dwelling unit on a property without municipal sewer in Pennsylvania, you need a sewage permit — and that starts with a soil evaluation and percolation test. This process is regulated by the PA Department of Environmental Protection (DEP) under Chapter 73 and administered by your county or municipal sewage enforcement officer (SEO).

At NEC Solutions LLC, we work with homeowners, developers, and real estate buyers to complete the soil testing required for the PA sewage permit process. We coordinate with licensed sewage enforcement officers, evaluate test results, and prepare the documentation needed for permit submission.

Percolation Test (Perc Test)Measures how quickly water drains through the soil to determine if the site can support a conventional or alternative septic system.
Soil Profile EvaluationHand-dug or machine-excavated test pits to evaluate soil type, texture, color, and the location of the limiting zone — the depth below which a septic system cannot be installed.
Sewage Module SupportDocumentation supporting the SEO's sewage module preparation — the official permit application for a new on-lot sewage system in Pennsylvania.
The PA Septic Permitting Process
1
Contact Your Township SEOThe sewage enforcement officer (SEO) oversees the permit. First step is contacting them to schedule a site evaluation.
2
Soil Evaluation & Perc TestThe SEO (and our engineers when engaged) evaluates soil conditions on site — test pits and percolation tests are performed.
3
System DesignBased on soil results, a licensed engineer or sewage enforcement officer designs the appropriate system type — conventional, mound, drip, or alternative.
4
Sewage Module SubmittedThe completed sewage module is submitted to the municipality — the official permit application. NEC Solutions prepares the engineering support documentation.
5
Permit IssuedOnce approved by the SEO and municipality, the sewage permit is issued and construction can begin.

Common Questions

Civil Engineering — FAQ

For many home additions in PA, the main requirement is a structural engineer for the PE-stamped structural drawings. However, if your addition adds impervious coverage (a roof, slab, or paved area) beyond a certain threshold, your municipality may require a stormwater management plan from a civil engineer as part of the permit application. We can handle both structural and civil components, which simplifies the process considerably.

Municipal review timelines for stormwater management plans in Pennsylvania vary by township and project size. Smaller residential projects reviewed by the township typically take 4–8 weeks. Larger land development projects subject to county review or PA DEP review can take longer. We prepare the plan to address all anticipated review comments on the first submission — which is the most effective way to minimize overall approval time.

A percolation test (perc test) measures how quickly water drains through the soil on your property. If you're installing a new septic system in Pennsylvania — for a new home, an addition of a bedroom, or any project that increases sewage flow — you'll need a perc test and soil evaluation as part of the sewage permit process. The test is performed on your site with the township sewage enforcement officer present. We coordinate and support this process for clients in Chester County and throughout eastern PA.

Yes. For new construction projects where the soil bearing capacity is unknown, or for sites with fill, disturbed soils, or a history of problems, a geotechnical investigation provides the soil data needed to design an appropriate foundation. We coordinate soil boring programs, evaluate the results, and prepare a geotechnical report with foundation design recommendations. This is especially valuable for commercial projects and any site with unusual soil conditions.

Yes — we regularly support developers and builders on residential subdivisions, commercial land development projects, and mixed-use developments. We can serve as the civil PE of record for land development plan submissions or provide specific civil components (stormwater management, grading plans, geotechnical reports) as part of a larger design team. Contact us to discuss the scope and how we can best support your project.

Yes — and this is one of the real advantages of working with NEC Solutions LLC. Many projects need both structural engineering (building design, PE-stamped drawings) and civil engineering (grading, drainage, geotechnical). Having one firm handle both disciplines eliminates coordination issues between consultants, simplifies communication for the client, and often reduces overall project cost and timeline.
