Stormwater Management
Practical stormwater design for new development and existing properties.
Stormwater requirements can shape a project from the earliest stages of planning. Elsa Associates provides stormwater management analysis and design for new development, redevelopment, and improvements to existing properties throughout Central Pennsylvania.
We work with you to understand the property, proposed improvements, drainage conditions, and applicable requirements, then develop a practical stormwater approach that fits the site and supports the overall project.
Effective stormwater design starts with understanding how water moves across the property and how proposed improvements will change those conditions. Elsa Associates evaluates runoff, drainage patterns, soils, topography, and site constraints to design infiltration, detention, conveyance, and other stormwater facilities appropriate for your project.


Stormwater design must also be clearly documented for municipal and agency review. Elsa Associates prepares stormwater management plans, calculations, reports, and supporting documentation and coordinates with reviewing engineers as the project moves through the approval process.
Additions, garages, patios, pools, driveways, and other improvements can create new stormwater requirements on properties that were developed long ago. Elsa Associates evaluates the proposed improvement and existing site conditions to develop a practical drainage and stormwater solution appropriate for your property.

Planning a Project?
Whether you are planning a new development or an improvement to an existing property, an early conversation can help identify the stormwater requirements and establish a practical path forward.
