The City of Morgan Hill wants volunteers to serve on its Planning Commission, which I can guarantee would be a great place for some good environmentalists. You have to be a City resident or in the City's Sphere of Influence, which extends a bit beyond the City's boundary.
City describes the Planning Commission below:
7-member Advisory Commission that serves as an advisory body to the City Council on matters related to city growth and development; and on such matters as may be requested by the City Council. The Commission meets on the second and fourth Tuesdays of each month at 7:00 p.m. Three vacancies to be filled by June 1, 2005 (4-year term).
For more information about applying, go to the City's website here, and scroll about half-way down. Feel free to contact me about it as well.
