Project requires submittal of WQMP a. Site flows are tributary to Lake Elsinore and will qualify for the “Highest and Best Use” exemption. b. Approved Preliminary WQMP due prior to Planning Commission. c. Approved Final WQMP due prior to grading permit or final map, whichever occurs first. d. All runoff from site shall be treated for pollutants of concern prior to release. 2. Project is required to detain the incremental 10-year pre- and post-development difference. 3. Any required storm drains larger than 36” is typically maintained by Riverside County Flood Control. Additional coordination with RCFC will be required. 4. Location of CDS unit seems to inconvenient for any future maintenance needs. It is recommended to relocate this unit away from entry gate, possibly closer towards Lot A. 5.

Once Scoping Agreement is approved, a Traffic Impact Analysis will need to be submitted for review and approval. 6. Project right-of-way dedication will be required on Mission Trail. Mission Trail is classified as an Urban Arterial Highway in the General Plan Circulation Element with 120 ft full-width right-of-way and 96 ft curb-to-curb. 7. Victorian Lane is identified as a Collector Highway in the City’s General Plan Circulation Element. The project will be required to dedicate right-of-way along the property frontage on the north side and construct half-width street improvements where the pavement section shall extend 12 feet beyond the half-width. 8.

Placement of utility facilities and landscaping shall not obstruct sight distances. a. The main entrance on Mission Trail will not be full access. 10. It is recommended to coordinate with SCE early and often in the development process to review load forecast and started advanced engineering study to determine the method and scope for providing service.
