WE’RE HIRING !!! Position available for GSI Landscape Designer

Ground Reconsidered is seeking a landscape designer or horticulturist with a focus in construction and installation oversight to support the implementation of Green Stormwater Infrastructure (GSI) systems for the City of Philadelphia’s Green City, Clean Waters (GCCW) Program.

About the GSI Unit

The GSI Unit was created to meet the commitments of the City’s GCCW Program for Combined Sewer Overflow Control. Within this unit, the Design group is tasked with creation and implementation of processes to identify, prioritize, design, and install City owned and operated GSI throughout the areas of Philadelphia served by the combined sewer system, as well as develop stream restoration projects.

Accepted by the Pennsylvania Department of Environmental Protection (PADEP) and the U.S. Environmental Protection Agency on June 1, 2011, the City of Philadelphia’s Green City, Clean Waters program is an ambitious plan to address the issue of combined sewer overflows in Philadelphia over 25 years through the management of runoff from more than a third of the impervious surfaces in the combined sewer system using GSI best practices.

GSI techniques seek to decentralize stormwater management, stem runoff at the source, and promote infiltration and groundwater recharge to help restore a more natural hydrologic cycle.  GSI manages stormwater using one or more of the source control processes of infiltration, evaporation, transpiration, decentralized storage, alternative stormwater routing, and reuse.

About the Landscape Design team

The Landscape Design team is a branch within the GSI Unit Design Program.  The Landscape Design team works with engineers and planners to facilitate projects from the planning phase through design and construction as well as provide procedural and technical support for the GSI Design & Construction groups. The team’s primary responsibilities include planning-phase concept developments, project design reviews, in-house landscape designs, construction-phase implementation of landscape components, landscape installation inspection, construction contract management, maintenance support and coordination, public outreach support (as needed), and landscape-related resource development for GSI Design and the GCCW Program.

About the GSI Landscape Designer Position

The GSI Landscape Designer will work with other staff and be responsible for tasks including, but not limited to:

  • Creating schematic concept design plans in conjunction with GSI Planning staff and community input from Public Affairs
  • Reviewing planning concepts for new GSI systems and field verifying existing conditions
  • Designing and developing landscape plans in AutoCAD for select projects
  • Conducting project design plan reviews for compliance with landscape practices
  • Conducting construction oversight of landscape installations of GSI projects
  • Inspections of systems prior to and after planting to ensure compliance with designs

  • Field data collections (e.g. DBH measurements) to inform GSI Design and operations
  • Analyzing data from tracked trees, soils, and landscaping using ArcGIS and Microsoft Access databases
  • Attending recurring on-site meetings, walk-throughs, and/or calls as necessary
  • Communicating landscape issues encountered during design development or construction implementation


Strong candidates for this position will possess 1-2 years of experience with these qualifications:

  • Experience with green stormwater infrastructure and low impact development stormwater management design and construction
