Residential Development Assessment
Challenge & Solution
Prior to purchase and development of a former electric company site located in Elizabeth Township, Pennsylvania, the private owner contracted an engineering firm to prepare all necessary reports and designs required for submittal of a subdivision Preliminary Application to the Township.
The primary firm was interested in aligning with small multi-disciplined firms to complete this fast-track project. Rhea was selected to join the design team to provide services in the areas of environmental assessment, right-of-way and deed research, cultural resources, erosion and stormwater control design, NPDES application, site layout design, and construction technical support.
Project Description & Highlights
The residential development is a 265-acre site located in Elizabeth Township, Pennsylvania. This site had been intended for residential development for over 30 years, but poor economic conditions in the region had halted the development. Recent transportation projects near the site have renewed interest in this R2-zoned property. Four hundred lots, each with an average size of 0.5 acre, were developed on the property.
Initially, Rhea performed the Phase I Environmental Site Assessment and Cultural Resource Study. Rhea also performed deed research and investigated the right-of-way requirements for the site and surrounding properties. Rhea’s civil site design for the project included developing the road layout, site grading design, sanitary sewer design, and storm sewer design. Rhea also designed the erosion and sediment control, stormwater management systems, and submitted the General NPDES Stormwater permit application for the project.
Performing the civil design for the residential development site was an engineering challenge due to the steep terrain and numerous gas service and transmission lines crossing the site.
Because of our extensive civil design expertise, Rhea developed a vertical layout design that both minimized and balanced cut and fill, the most critical cost issues for a developer. In addition, the General NPDES permit application was accepted after minor comments.
