Greystone Walk Subdivision

West Goshen Township – Jerrehian Estates/NV Homes

Edward B. Walsh & Associates, Inc. (EBWA) was commissioned by the Jerrehian Estate to provide boundary and topographic surveys and civil engineering design services related to the development of a 20.5 acre tract of ground in West Goshen Township Chester County, PA into 25 single family lots. EBWA provided road design, grading, stormwater management and erosion control. EBWA also attended and presented before the Planning Commission and Township Supervisors for approvals.

The design of the road entering the site required a stream crossing and construction of a three cell concrete box culvert. As part of the design, flood plain analysis was required for testimony at the Township Zoning Hearing Board to allow for a flood plain crossing. Permits were also required and obtained from the PA DEP.

In addition, EBWA was commissioned by NV Homes to provide lot site design services related to house placement, grading, and survey stakeout prior to construction. As-built survey services were provided after construction.

Sage Hill Subdivision

Thornbury Township – Moser Builders

Edward B. Walsh & Associates, Inc. (EBWA) was able to work with an established builder to generate a 22 lot single family residential subdivision on a property in Thornbury Township, Chester County, PA. Given the site limitations posed by the municipality code with respect to the floodplain, the property had been evaluated by other builders and considered too challenging to successfully develop.

With EBWA’s knowledge of floodplain studies and FEMA requirements, the staff was able to perform a floodplain analysis and generate a plan with an increased lot yield for the client. EBWA created a layout with substantial open space with 90% of the lots being located along the open space. EBWA also carefully designed the stormwater management systems to have them located in the open space therefore not encumbering the individual lots.

The resulting product was a desired, award-winning residential subdivision.
