The applicant is not requesting concurrence from DWR on streamflow regime, and I am not familiar with the requirement to have a DWR stream ID form for each feature. As DWR jurisdiction extends to all US Army Corps regulated features, the issued PJD has been provided to document the presence of jurisdictional streams/tributaries on the site.

I have some additional comments: • Please provide a stream restoration detail for the sewer utility installation stream and wetland impact locations. • Please provide the DWR stream form used for stream identification on -site for all streams. Per our division's rules we must have documents identifying intermittent and perennial streams. Please reach out if you have any questions.

Please correct this. If they are perennial impacts then please update the SOA from DIMS. Please let me know if you have any questions. Thanks!

Samantha, Please see the following responses: 1. Please provide an additional overview map with clear parcel boundaries of the project area. The current maps (Figure 1, Stream Crossing — Existing Conditions, and Stream Crossing — Overall Site Plan) are hard to understand. See attached SheetX-114 Full Overall Site Plan 2. On Figure 1 supplied by Wetlands & Waters, Inc. there are four tax pins provided (3543075624, 3533779760, 3533789387, 3533795446). There are only three listed on the map. Are there four parcels included in this project area? If so, please provide the deed information. If the fourth parcel is being included, can that area be used to minimize impacts? This parcel is included (Deed Book 4104/Deed Page 1817). It is composed entirely of uplands and was added to the assemblage and utilized to maximize avoidance and minimization by moving the road crossing above the existing stream and wetlands.
