Policy Solution

Parks and open space



Converting vacant, non-vegetated land into parks and open spaces is a heat mitigation strategy that cools the surrounding temperature and also provides social co-benefits.


Develop and adopt parks plans and capital plans to fund park networks.

Considerations for Use

Parks can be capitally-intensive to design and construct; but offer many opportunities for funding through increased property values and financing solutions. Parks require ongoing maintenance.
