Worthing, Newtown Township, Delaware County, PA

Nave Newell prepared land development plans for this 32 acre residential parcel. Initial plans provided for 17 single family homes along a proposed cul-de-sac, with two stormwater management basins and public water and sewer. Nave Newell obtained Preliminary and Final Land Development Approval, secured Conditional Use Approval for steep slope disturbance, and provided two emergency access lanes due to the length of cul-de-sac. E&S Control Plan approval from the Delaware County Conservation District and an NPDES Permit were obtained. A Planning Module approval was acquired along with a Part II Permit (due to need for grinder pumps for some lots). Additionally, Nave Newell prepared plans for the water main to serve the subdivision. Approval from Aqua PA and a PennDOT Highway Occupancy Permit were also required.

A second set of land development plans, with an 18 lot layout, were prepared in the middle of the project per the client’s request. Even though the new layout only affected a few lots, the plan set was considered a separate submittal by the Township, and separate Township approvals, as well as another Planning Module approval, were required. Ultimately, the 18 lot layout plans were recorded.


Dupont Property, East Fallowfield/West Bradford Townships, Chester County, PA

Nave Newell prepared an environmental analysis to determine the best way to meet the Township's desire for a cluster community. The resulting Unified Development Area (UDA) Master Plan created a 284 single-family-lot subdivision with two conservation lots, which preserved mature woodlands, steep slopes, wetland areas, and view sheds for this 540-acre parcel.

Working closely with the Brandywine Conservancy and the Township Planning Commission, Nave Newell designed a stormwater management system that incorporated creative best management practices for groundwater recharge in a High Quality Watershed. Nave Newell also developed a layout for the sanitary sewer system, which saved construction costs by eliminating the need for two pump stations.

Whitegate, Upper Merion Township, Montgomery County, PA

This 75-acre site presented several development challenges for the developer/builder, mostly due to the rolling topography and the presence of Core Creek, which bisected the site. In addition, the northern portion of the property was bound by Norfolk Southern Rail right-of-way. Nave Newell was retained to design a community that would support 69 lots for single-family home construction in one of Montgomery County’s most affluent communities. The success of this project came in part because of the seamless coordination with different stakeholders in the project; Nave Newell handled the regulatory compliance, permitting, and representation before local and state regulatory agencies.

The stream corridor was preserved and the lots were situated to take advantage of scenic views. A floodplain analysis of Core Creek was conducted and incorporated into the stormwater management design. Utility easements and maintenance agreements were required for one of the proposed stormwater management basins, which discharged into the rail line’s right-of-way. Approximately 850 ft of existing sanitary sewer main was relocated to reduce impacts to several lots and to locate the sewer within the public road right-of-way for future ease of maintenance.

Tattersall Golf Community, West Bradford Township, Chester County, PA

Nave Newell completed the site engineering for this 450-acre golf course community. The community consisted of 164 single-family homes in six pods that are clustered around a 291-acre golf course. The project was extremely complex due to its topography, wetland requirements and necessary PennDOT permits. Steep slopes and wetlands with an exceptional value rating were present at the site location, thus necessitating the design of a complex erosion and sedimentation control program. The creative layout of the sanitary sewer system resulted in the elimination of a pump station. The golf course cart path system required the construction of a culvert to cross under a PennDOT highway.

Nave Newell assisted the Client in obtaining E&S approval from the Chester County Conservation District and a Phased Individual NPDES Permit so construction of the golf course could be started while the remaining approvals for the residential phases were obtained.

Nave Newell also renewed the Individual NPDES permit for the project which was subject to new stormwater management requirements and resulted in a redesign of a portion of the lot layout and stormwater system to comply with the new regulations.
