Requires green building standards and impact studies for carbon, traffic, storm water, and schools for certain affordable housing development.

This bill requires new affordable housing developments (10+ units or 4+ stories) to meet minimum green building standards, such as LEED Silver certification, and conduct specific impact studies. Developers must submit traffic, school, stormwater, and carbon impact reports (for projects clearing over one acre) to local municipalities before construction. It applies only to new projects, not those with applications submitted before the bill's effective date. The law directs the Community Affairs Commissioner to create implementing rules within eight months of enactment.
