PWD Planting Soil was originally developed by the Philadelphia Water Department as part of a large green infrastructure policy. The benefits of greening an urban environment are Nemours. Trees and plantings absorbe rain water, provide shade, animal and insect habitat, clean the air and beautify the landscape. PWD Planting Soil was designed for urban tree plantings and has since been adopted as a great all-purpose landscape soil. PWD requires blenders to certify their compliance of this mix twice a year. Laurel Valley Soils has been involved with the PWD Green Infrastructure program from inception and has been an approved supplier every year. The performance of this soil is extremely consistent, adhering to a specification which ingredients are blended to meet a very strict set of parameters. LVS PWD Planting Soil is a well-balanced loam soil with a rich dark brown color, is screened to a half inch, and is stored out of the elements in an expansive covered building. Because of our large scale infrastructure and state of the art equipment, we are able to stockpile inventories so that we can provide our soil year round to meet our customers’ needs, whether that be one truck load or a thousand truck loads.

PWD Stormwater Soil was originally developed by the Philadelphia Water Department as part of a large green infrastructure policy. The PWD Stormwater Soil was designed to mitigate stormwater runoff when used in applications such as rain gardens, bioretention basins and bioswales. The soil is designed to absorb, infiltrate, and filter stormwater runoff into the ground where it can safely recharge groundwater systems and reduce surface flooding. PWD requires blenders to certify their compliance of this mix twice a year. Laurel Valley Soils has been involved with the PWD Green Infrastructure program from inception and has been an approved supplier every year. Many other cities and municipalities have since adopted this well preforming specification. The goal of a bioretention basin is to capture and divert stormwater runoff displaced from impervious surfaces. Well-designed basins also filter out untreated pollutants that otherwise might flow directly into waterways. Many bioretention basins are large in scale and while they can have attractive plantings, these utilitarian designed basins are generally located out of sight, at the low end of a parking lot or downslope from a building or road.
A stormwater management plan is now a requirement with all new construction that creates impervious surfaces. Water must be contained on site or at least slowed down to prevent flooding and pollutant movement. Bioretention basins are part of the building and zoning code and are required for most building projects including renovations and expansions. The understanding and design of these soils is evolving rapidly.
Many projects have unique site conditions and landscape design criteria which can require custom soil solutions. We can create most engineered custom blended soils to fit your project’s design and performance requirements and in the absence of a specification we can offer one of our many off the shelf engineered soil options or collaborate to develop a site specific mix. We can make biosoils, rain garden soils, structural soils, light weight soils, planting soils, rootzone sports turf soils, container/planter soils and more.
For Engineers and Landscape Architects looking ahead to incorporate new specifications for future projects, we can also provide guidance and consultation for creating new custom specifications.
