Design Review and Reimbursement

Green Roof Projects

Green roof projects will undergo an advanced schematic, 75%, and 100% design review process with a two-week DEP review time for each phase. Funding for green roofs is determined by green roof area (GRA) and soil depth. The schedule below outlines the maximum reimbursement rate for green roof projects. Projects below the minimum criteria, 1.5″ soil depth and 3,500 SF, are not eligible for grant funding.

Reimbursement Rates ($/SF) for Green Roof Projects

Soil Depth (in.) 3,500-20,000 (SF)*
* The reimbursement rate for SF of planted area over 20,000 SF is calculated using 50% of the rate shown above
1.5–1.99 $10
2.0–2.99 $15
3.0–3.99 $25
4.0 + $30

Infiltration Projects

Infiltration projects will undergo an advanced schematic, 75%, and 100% design review process with a one-month DEP review time for each phase. If accepted, DEP will provide funding for the design and construction of these projects. All infiltration projects must meet the following criteria:

  • Manage 1″ of rainfall from the contributing impervious surface
