Hi Robert,
I just wanted to follow up to this conversation you had with Chonticha. DWR is considering the application on hold again
until we receive a complete response to the items below. As you know, DWR is mandated by federal rule to make a final
401 decision within a certain timeframe. For this project that timeframe is mid May but I will be instructing at Stream ID
class the entire week of the 15t" so I will need to make a final decision on this project the week before that. Backing up
time for Chonticha to carefully review what you send, we will need a complete response by 4/20/23.
Thanks,

Hi Robert,
As a follow up to our meeting earlier this morning, here is a list of items I need in order to continue my review of this
project.
1. Please review and revise the pond identification to Al, A2, and A3. Check the plans and other documents
(including Table 10 on the SWU-101 form) to make sure they are being referenced correctly and consistently.
2. For Building#1 Site - Please review the drainage map and clarify stormwater routing/treatment of post-DA2
(additional truck parking lot). See the snapshot from plan sheet C-907 below:

3.
Please review and clarify if pond Al will have an outlet structure and where its outfall location is located. Please
provide additional drawing or modify plan sheet C-402 to clearly show outlet and routing of treated stormwater
leaving pond Al.
4. Please identify the discharging source and purpose of an outlet dissipator pad shown on plan sheet C-402 (see
the snapshot below); the pad is circled in red.
5. Please include narrative and the sizing/capacity calculations of the underground detention system (Stormtech)
in the stormwater report for Building#1.

6. Please provide profile drawing details (ex. temporary pool, permanent pool, sediment storage/removal, & pond
bottom elevations, etc.) for pond A2 and A3. The submitted plan sheet C-405 only shows a generic pond profile
and does not include any site specific elevation details.
7. For all ponds (Al, A2, & A3), please add a liner note to investigate/determine SHWT elevation where each pond
is located and specify liner requirements if pond will be sitting in the SHWT, to prevent groundwater seepage
which may jeopardize or decrease pond's capacity.
8. Please add planting plan for the vegetated shelf to the detailed drawing of each pond. Note that the minimum
design criteria requires at least 3 diverse species of herbaceous, native vegetation (min. density of 50 plants/200
sq•ft of shelf area).
Please forward this email to other parties in the meeting and let me know if you have any questions. Thanks again for
taking the time to meet with me and for your cooperation.
