On Wednesday May 29, engineers from D.L. Howell and Associates attended the groundbreaking for the Flats at Kennett luxury apartment complex on Millers Hill Road in Kennett Township. The event was well attended by the developer’s team, project consultants, Kennett Township officials, and local news media. The D.L. Howell engineering team worked closely with High Associates, to ensure that the project approvals from Kennett Township, Chester County Conservation District, and the Pennsylvania Department of Environmental Protection were received in a time frame to allow for construction to commence this summer.
The project consists of three buildings and a total of 175 luxury apartment units ranging in size from one to three bedrooms. Several luxury amenities are proposed including quartz countertops, stainless steel appliances, a fitness center with state-of-the art equipment, under-cabinet lighting, an outdoor pool and fire pit with conversation area, a yoga studio, a pet spa and a bike storage facility. The project is planned to be completed next year.
D.L. Howell is proud to have been a part of this exciting project and we look forward to working with High Associates on additional projects in the future.
When designing stormwater for a project, we must consider stormwater runoff for both rate and volume. Peak rate is the easier of the two to control as we can manage the rate in a stormwater basin, berm, rain garden, bed, etc. The peak rate management does not have to rely on the on-site soil conditions as the volume control does.
Typically, the runoff volume is managed by infiltrating the change in
two-year runoff volume when comparing the pre-development to
The problem with infiltration is that not all soils and site conditions allow for infiltration. There can be many factors or limiting zones that prevent infiltration on site, one of the most common limiting zones we encounter is shallow bedrock. Other limiting zones might be high water table, mottling, or clayey soils that do not infiltrate.
Last month, Pennsylvania DEP released a white paper on a ‘Managed Release Concept’ (MRC). The MRC is a post-construction stormwater method that manages the increase in stormwater runoff volume through storage and filtration of stormwater runoff. In the white paper, DEP provides guidance for when an MRC is applicable and also the methods for implementing an MRC into the site design. Using an MRC does not exclude the site from all infiltration. If there are some areas within the site to provide infiltration, infiltration must be maximized in those areas. The designer is required to provide an adequate site assessment of soils and geology to demonstrate that infiltration of the entire change in two-year runoff volume is not feasible. If the conditions are met, then the designer can request from the Conservation District and/or DEP for authorization to proceed with the MRC design.

While the children have been enjoying their time out of school this summer, the team at D.L. Howell has been hard at work to prepare plans for a new Uwchlan Hills Elementary School. We have been working very closely with the Downingtown Area School District and KCBA Architects to prepare a design for this exciting project. The plans have gone through a sketch plan review, conditional use hearing, and are now in for review for preliminary/final land development approval.
The design comes with some challenges as the new school is going to be built on site while the existing school is still in operation. We have to be very conscious of the safety and well being of the students while construction is on-going. This requires a very detailed construction sequence that includes the installation of perimeter fencing around the construction zone and a separate construction driveway.
There are additional challenges with the site as there are several natural resources on site, we have prepared a design that will protect them to the greatest extent possible. A large portion of the site consists of wooded areas that we are minimizing the disturbance of. This wooded area provides a well-established buffer from neighboring residential properties and commercial properties. The site is also adjacent to a tributary to the East Branch of the Brandywine Creek, which is a high-quality watercourse as it passes through Uwchlan Township. A stream under this designation requires a 150-foot riparian buffer, which the design also protects.
The project is currently on schedule for a spring 2019 start with a fall 2020 opening of the new school.
The RV business is booming at Stoltzfus RV and Marine on Route 202 in Birmingham Township, Chester County. D.L. Howell was contracted by Stoltzfus RV to secure approvals for the proposed expansion of the lot adjacent to the existing Stoltzfus RV site. The 13,750 square foot building will be used to service and maintain the customer’s RVs. The project required a range of approvals including conditional use, land development, NPDES, and PennDOT. Additional approvals were needed from Thornbury Township for the discharge of the stormwater management to the existing basin on the current Stoltzfus RV site.
D.L. Howell enjoyed this opportunity to work closely with Earl Stoltzfus and his team throughout the entire process and also with Anthony Diver and the Tamora Building Systems team during construction.
D.L. Howell has enjoyed working closely with Stonehaven Homes for several months on some exciting residential developments in both Easttown/Tredyffrin Township Chester County and Middletown Township, Bucks County.
Last week, the Easttown Township Board of Supervisors granted preliminary/final approval for the seven-lot Berwyn Village Subdivision. The cul-de-sac community being developed by Stonehaven Homes will consist of six new single-family homes and seventh home being a restored farmhouse. Berwyn Village is conveniently located within walking distance to the Berwyn Station and the pedestrian bridge to cross into the heart of Berwyn.
In addition to the seven single-family homes as part of this approval, there are plans in the works for a community right next door for an additional 18 single-family homes. With all the conveniences located so close, it is expected that these beautiful homes will sell quick.
If this isn’t the location you were looking for, you can also check another recently approved Stonehaven Homes community, Oakview Estates located in Langhorne, Bucks County. This ten-lot community is located directly across the street from the community full of multi-use trails and playgrounds. These homes are already selling quick and won’t last long.
