A CBP3 (Community-based Public Private Partnership) is a performance-based contract between the public sector and the private sector to do some or all of design, build, financing, operate, and maintain public infrastructure. The approach is centered around community governance and makes a focused effort to provide for local economic growth and improved quality of life, often in urban and underserved communities.

An EIB (Environmental Impact Bond) is an environmental outcome-focused bond that functions as a debt security issued to finance capital expenditures. It is backed by the payor with regular payments of interest and full repayment of principal at the end of the term.  Typically, it is structured to incentivize innovation by sharing risk between the payor and the private investors.

Stormwater credit trading

Credit trading programs enable property owners who are subject to an on-site stormwater retention requirement to meet a portion of their requirements by buying stormwater “credits” from other property owners rather than building all needed GSI on their own property.
