Site Engineering


Reducing development costs by resolving site challenges is one of our top priorities.

The fundamental element in quality site engineering is proper site grading. It provides the most efficient use of the site, creates building lots that drain properly, balances earthwork quantities so costs are minimized and optimizes the design of efficient road, sewer, and storm drain systems.

Our success has been the result of innovative concepts, constructible designs, and a high level of service to our clients.

County Seat Apartments, Georgetown, DE

County Seat Apartments Illustrative 1000pxThis site consists of eight apartment buildings housing a total of 187 units, a 2,700-SF clubhouse, pool, tot-lot, numerous open space pockets, and extensive landscaping that satisfied Georgetown’s rigorous design standards. Working closely with local tax ditch managers (including State Judge/Court), Federal Emergency Management Agency (FEMA), Delaware Department of Natural Resources and Environmental Control, Sussex Soil Conservation District, and City of Georgetown Engineers, the project team was able to deliver a holistic solution for floodplain, tax ditch and stormwater management (SWM) issues that minimized land disturbance and maximized buildable acreage.

In addition to the full spectrum of on-site civil engineering/ design services (including design of all roads, storm drains, sediment and erosion control), MRA also provided post construction as-built services for the utilities and SWM facilities.  Design for 1,500 LF+/- of widening and frontage improvements to Vaughn Road have been provided by MRA in conjunction with the development of this residential community.

MRA also provided planning, design and construction services for a 0.84-MGD regional sewage pumping station, 6,700 lf of 8-inch force main, and 400 lf of 16-inch force main, including 100 LF of 20” steel sleeve and 1,000 LF installed by direction drilling to serve the County Seat Apartment complex. The sewage pumping station discharged into a common force main which required the selected pumps to operate within a variable pressure range.

Claymont Library, New Castle, DE

Claymont Library 1000 x 650

MRA provided project management, architecture, structural and civil engineering, landscape architecture, and surveying services for the new 17,472-GSF library, with expansion capabilities to 22,000 SF.

Designing the Claymont Library was quite a challenge. The site was covered with three stormwater management ponds that serviced the surrounding 60-acre residential development. The Friends of the Claymont Library requested a landmark building with a “wow” factor that would address all of Claymont, not just the immediate neighborhood. MRA reengineered the existing stormwater management ponds, creating a hilltop parcel overlooking the residences, serving as a prominent focal point for a future boulevard. Tremendous cost savings were realized though a careful grading/earthwork analysis while still satisfying structural fill requirements. MRA also rewrote the Neighborhood Design Guidelines, on behalf of the County, to allow us to locate parking conveniently near the front door, while depressing the grade elevation in order to screen the parked cars from the neighborhood.
