On March 22, 2017, the Division of Water Resources (DWR) received a close-out packet from you on
behalf of the Division of Mitigation Services (DMS) requesting approval to close-out the subject site from
monitoring and maintenance of the riparian areas. On April 26, 2017, Mac Haupt (on behalf of Katie
Merritt) with DWR visited the subject site to assess the vegetation and overall site conditions. An asset
map is attached.
As a result of Ms. Merritt's review of the close-out request and site review from Mr. Haupt the following
mitigation is approved:
