More than 3,000 Portland families in mobile and manufactured home parks stand to get new assurances their complexes won't be redeveloped for other uses, alleviating their fears of getting kicked out.

The city Planning and Sustainability Commission voted 7-2 last Tuesday to rezone 56 mobile and manufactured home parks in the city with a new "residential manufactured dwelling park" designation. The move is designed to protect affordable housing by thwarting redevelopment of the parks into apartments or other more lucrative investments.
