Zentner Planning and Ecology has been in the forefront of ecological restoration design and construction since 1986 when the company was founded, based on the belief that quality restoration work informed permitting and planning.  In short, we learned, often the hard way, how to restore successful habitats, from wetlands and vernal pools to native grasslands and oak woodlands.  That hard-won success allows us to propose solutions that work for both permitting and planning issues.

We are a certified Small Business Enterprise (SBE) with the State of California, the Port of Oakland, and the Valley Transportation Authority (VTA). We are:
