Chapman & Patton


History - Over 40 Years of Experience

The firm of Chapman & Patton (formerly Dean Chapman & Associates) was established in 1999 and has a focus on eminent domain assignments in which both public agencies and private property owners are our clients. As pictured above, Mount Diablo is the landmark that separates our two offices, with one nestled at the base of the mountain in Danville, and the other being located in the eastern part of the Central Valley, in Oakdale. We have completed a wide assortment of eminent domain appraisal assignments, as well as various other appraisal-related consulting assignments. Complex appraisal problems throughout California are our specialty, from Los Angeles County to the south and Butte County to the north. Click here to download the firm’s Qualifications.

Our pledge to independence and expertise is evidenced by our numerous professional designations and training. Our commitment to integrity and success is demonstrated by our leadership experience within the Appraisal Institute and IRWA (International Right of Way Association).
