Answer: I'd love to be able to advise you, but without an opportunity to inspect the site, analyze the soil and the natural drainage of the site, I can't really offer any opinions. If it were my property I'd either get a second opinion or I'd talk to someone at the local cooperative extension office that specializes in onsite drainage. Contact University of California Cooperative Extension, 4145 Branch Center Rd, Sacramento, CA 95827-3823 phone (916) 875-6913. Or, contact your county building department for expert advice. Wish I had more to share.
