TR/PM NO. DORAN STREET GRADE
SEPARATION
PLAN CHECK NO. 1
TRANSMITTAL DATE: 03/26/2024
PLANS ARE DISAPPROVED
We have reviewed the plans for the proposed drainage improvements. Make corrections as shown on the returned set of plans and as noted below. Address all additional comments indicated in red on the returned set of project plan. Additional changes may be required as determined by further review.
After the revisions are corrected and approved, it will be necessary to obtain a Connection and/or Inspection Permit for the proposed drainage improvements prior to the commencement of construction. ☒ Army Corps 404 Permit, Regional Water Quality Control Board permit, & State Fish & Wildlife Permit may be required. ☒ Submit the Draft copies of the Corps 404 Permit, Regional Water Quality Control Board permit, & State Fish & Wildlife Permit for review before signing them.
☒ Army Corps of Engineers Connection Permit is required.
COVER SHEET COMMENTS
☒ All sheets must be stamped and signed by a valid Registered California Civil Engineer with current license. ☒ Make the indicated changes to the Hydraulic Elements Table. Discrepancies were found between the Hydraulic Elements Table and profiles.
GENERAL COMMENTS
☒ Provide rubber gaskets to 3 joints or 24’ (whichever is greater) in both directions of a cut/fill transition. ☒ Submit revised cost estimate.
CATCH BASIN COMMENTS
☒ Provide v-depth calculations for all catch basins. Minimum v-depth is 4.5’ per SPPWC. ☒ All catch basins require both Automatic Retractable Screen (ARS) devices and Connector Pipe Screen (CPS) devices to be installed.
EASEMENT COMMENTS
☒ Provide an exhibit sheet on your plans showing the storm drain system, all public right of ways, and all easements (including bearings and distances, who they will be dedicated to, and how they will be dedicated).
Exhibit 3
☒ Provide a copy of the Final Map/Separate Instrument for checking all easements and easement call -outs. ☒ Clarify if any existing easements need to be abandoned where the proposed drains connect to existing systems. ☒ All easements shall be made to The City of Glendale and be written so they can ultimately transfer to LACFCD.
SOILS COMMENTS
☒ The plans must be signed and stamped by a valid California Soils Engineer. ☒ Provide a soils report that specifically address es the proposed storm drain. It must include sufficient subsurface exploration data, pertinent test results and analyses, which address and evaluate the site , the proposed storm drain plans, analysis of channels, top berm widths less than 20 feet, analysis o f subdrainage system, suitability of existing soils, placement of storm drain next to faults, etc . The report must comply with the provisions of "Manual for Preparation of Geotechnical Reports" prepared by County of Los Angeles, Department of Public Works. (Note: Tract grading reports are not sufficient. An addendum soils report which specifically address the latest storm drain plans is required. This addendum report may utilize and compile results of previous subsurface exploration, as applicable.) ☒ Comply with the Soils and Geology Section comments. (If applicable)
TRANSFER DRAIN COMMENTS
☒ Provide an exhibit sheet on your plans showing the storm drain system, all public right of ways, and all easements (including bearings and distances, who they will be dedicated to, and how they will be dedicated). ☒ Pay a fee to start the transfer drain process once this drain has been completed. See current fee schedule. ☒ Pay a fee to prepare, process, and/or quitclaim all necessary easements. See current fee schedule. ☒ Submit an 8 ½ X 11 copy of the key map.
☒ Storm Drain will not be eligible for transfer until all easements have been dedicated and or quitclaimed to the Los Angeles County Flood Control District (LACFCD).
MISCELLANEOUS COMMENTS
☒ A pipe inspection fee will be required prior to issuance of permit. ☒ Address all additional comments indicated in red on the returned set of project plan.

Kourosh,
Good afternoon, I will forward the maintenance comment response over to our maintenance team and get back to you on their response.
Regarding the other questions
1. Please use the Design WSE. In your HEC-RAS results you show a Design WSE value right? Please use that as the control WSE of the downstream connection. If it is still below the invert, that is fine.
2. We will need the property owner (in this case the City), to grant an easement to the Los Angeles County Flood Control District prior to transfer. If the property owner if the City, then no action is needed prior to approval of plans as it is a public owner. With that said, please label the 10' minimum width easement on the plans. The plans should show the ultimate transferred condition which should say "10' Storm Drain Easement to Los Angeles County Flood Control District per Separate Instrument XXXX dated XX/XX/XXXX". That will be a placeholder on the plans until time of transfer.
3. To be honest that easement is causing me a bit of confusion. I think all we will need on this set, since its only a small portion of easement, is the easement called out on the plan view with acknowledgement label that the property owner is the City of Glendale.
4. Noted about the existing condition.
Please let me know if you need anything else, thanks.
