Hi Jean,
Closing the loop on this.
The stage storage HydroCAD worksheet tables (as requested per SC#16) are attached and were also
included in our response letter dated October 8, 2024. No changes were made to the storage volumes
following the issuance of the WSP. The only modification to the stormwater design was the revision of the
bioretention basins to infiltration basins, based on the observed Estimated Seasonal High Groundwater
(ESHGW) elevation.
Regarding SC#17, the test pits were conducted on November 6, 2024, prior to the issuance of the OOC.
The test pit observation report is attached and also included in the appendices of the project specifications.
Please reach out with any questions!
Thank you,
Jamie
