I want to express my greatest thanks for the excellent roofing, siding replacement, ADA hand rail, and concrete work you performed. Kaiser Permanente and PG&E were very pleased with your work.

Useful Info for Pleasant Hill CA

Pleasant Hill, CA is different from the surrounding cities and towns in one significant way. As was common among most California settlements, it started out as farmland. But at the end of WWII, Walnut Creek grew into a San Francisco Bay area bedroom community with no other significant industry. The first post office was not established until the extremely late date of 1948, and the city itself was not incorporated until 1961. The city may have been late in incorporating, but the current residents knew what they wanted, which was a beautiful downtown area where any existing buildings were refurbished instead of replaced.

In 1974 the city developed and committed to their Pleasant Hill Redevelopment Plan. Even thought it took almost 25 years to be fully implemented, the plan provided for both the funding and architectural plans necessary to make this downtown dream a reality. The plan included specific zoning requirements which produced the end result of a beautiful and functional downtown. Opening for business in 2000, the citys goal of having a vibrant and historic main street was achieved. Pleasant Hill has subsequently received several awards for their architectural designs and their implementation.
