Residential Civil Engineering in the Harrisburg Area
Practical engineering for homeowners and builders throughout the Harrisburg region.
Elsa Associates is a civil engineering firm based in Hummelstown, serving homeowners, builders, and property owners throughout the Harrisburg area. Many residential projects need engineering for reasons that are not obvious at first: a municipal stormwater requirement for an addition, a drainage problem that keeps returning, or a lot that needs a grading plan before a new home can be permitted.
You work directly with Michael Bruce, PE, from the first conversation through approval and construction.
Stormwater for Home Improvements
Additions, garages, patios, pools, and driveways can trigger municipal stormwater requirements, even on properties that have never had a drainage problem. Requirements vary from one municipality to the next, so the first step is determining what the applicable ordinance actually requires, including whether an exemption or simplified process applies.
When stormwater management is required, Elsa Associates designs a practical solution and prepares the plans and supporting documents needed for approval. New to the process? Read our Stormwater Management Basics for Homeowners guide.
Drainage Problems on Existing Properties
Standing water, wet yards, erosion, and water flowing toward buildings often have a clear cause once the property is evaluated as a whole. Elsa Associates evaluates grades, runoff patterns, and existing drainage features, then develops practical improvements such as regrading, swales, yard drains, piping, or infiltration.

New Homes and Small Lots
Builders and owners developing a single lot or a small group of homes need site plans that work with the property and the municipal requirements. Elsa Associates prepares grading, drainage, utility, and stormwater designs, and coordinates subdivision or land development approvals when they are required.

Areas We Serve
Elsa Associates works throughout the Harrisburg region, including Harrisburg, Lower Paxton Township, Susquehanna Township, Swatara Township, Linglestown, Hummelstown, Hershey and Derry Township, Middletown, Camp Hill, Mechanicsburg, and Carlisle.
Each municipality has its own ordinances, review procedures, and expectations. Understanding those differences early helps keep residential projects moving. Elsa Associates also serves the York and Lancaster areas.
A Local Engineer You Can Reach
Residential projects rarely need a large firm. They need an engineer who answers the phone, understands the local requirements, and keeps the scope proportionate to the project.
Elsa Associates provides direct access to the engineer responsible for your project. Learn more about Elsa Associates or read what clients say.
