You probably don't have any idea who I am, but I just wanted to reach out to you and let you know how much I appreciate the great work you are doing. I just got done reviewing a SWPPP you prepared for Clay Park in San Diego. I have reviewed a few other SWPPPs you have prepared in the past and they are always really well done. As soon as I see your name on the SWPPP I know it will be a good one. Thanks for all you do!
