Now protecting more than 3,400 acres

By storing and draining water into the ground naturally, Greenseams® helps prevent future flooding and water pollution while supporting and protecting MMSD's structural flood management projects - infrastructure investments worth hundreds of millions of dollars. Greenseams® is an innovative flood management program that permanently protects key lands containing water absorbing soils.

The program makes voluntary purchases of undeveloped, privately owned properties in areas expected to have major growth in the next 20 years and open space along streams, shorelines and wetlands.

Take a virtual tour of the Greenseams® properties by selecting one of the counties listed below.

More than 100,000 trees planted

All land acquired will remain undeveloped. Wetlands maintenance and restoration at these sites will provide further water storage. Greenseams® also preserves wildlife habitat and creates recreational opportunities for people living in the region. Where applicable, the properties can be used for hiking, bird watching, and other passive recreation.

The Conservation Fund (TCF)

MMSD hired The Conservation Fund (TCF) to run Greenseams®. TCF is a national non-profit conservation organization that forges partnerships to protect America's legacy of land and water resources. TCF performs high volume real estate transactions for local land trusts and government agencies throughout the country.
