o Site flows will drain towards Lake Elsinore and would qualify for the “Highest and Best Use”
exemption. Infiltration will not be allowed. Bioretention/Biotreatment is preferred.
o Please comment #3 regarding infiltration rates.
o Approved Preliminary WQMP due prior to Planning Commission. To attain approval of the
Preliminary WQMP, the project shall submit through the City’s Self-Service Portal for a

o Approved Final WQMP due prior to grading permit.
o All runoff from site shall be treated for pollutants of concern prior to release.
2. For Geotechnical Update report by Geocon West Inc. dated February 22, 2022, please provide a
thorough narrative of the percolation testing. Please see Appendix A of the RCFC LID BMP
Handbook minimum requirements.
3. For Geotechnical Update, please verify and revise results as outlined in Table 7: Infiltration Test
Rates for Percolation Areas. Based on test results provided, infiltration rates for P -2 and P-4 would
be 0.35 and 0.22 in/hr., respectively. LID Infiltration BMPs are not acceptable if infiltration rates
below 1.6 in/hr.
4. Attached are additional comments to the Geotechnical Update. Please revise and resubmit.
5. Please include narrative and summary of the project’s pre -development and post-development
conditions. Additional comments are provided in the Drainage Study. Please revise and resubmit.
6. Preliminary grading plans show weep holes oriented to adjacent property to the east. Please
provide drainage acceptance letter from property owner.
7. Project is within the 100-yr floodplain.
o Building foundations will be required to be raised above the floodplain plus three (3) feet per
Lake Elsinore Municipal Code 15.68.020.
▪ Review LEMC 15.64 and 15.68 for Flood Damage Prevention and Floodplain
Management requirements.
o No import is allowed from outside the lake area and project shall balance on site.
