We will need 2 - 3 copies of drawings for plan check (refer to table below). One will be red lined with plan check corrections and returned to the designer, the other(s) saved as a record of you submittal. Upon completion of the plan corrections, re-submittal of the original red line copy is required.

Once the final corrections have been made and the plan is ready for signature, Mylar "originals" are required. These will become permanent records with the city. If copies are needed, the plan may be "check-out" for duplication but must be returned.

Plan Submittal - Required Number of Sets

Plan Check Fees

Plan check fees must be paid for prior to final approval. Typically, plan check fees are calculated during the first plan check. The plan check fee will be noted on the return transmittal form. Refer to our Fee Schedule for all Engineering fees.

Drawing Format

Plan Size:

A standard "D" size plan sheet (24"x36") is preferred, but if your project is large enough, an "E" size sheet (30"x42") may be used. Larger plan sheet sizes are discouraged. Drawing scale should be used to convey the information clearly. A large scale makes the plan easy to read, but can produce an excessive number of sheets. A small scale will allow the "big picture", but may reduce the visibility of important information. Typically, Street Improvement Plans are drawn at 1"=40'; Grading Plans at 1"=10' or 1"=20'.

Plan Media:

For all plan check submittals, only paper copies of the original drawing is required. At the time of plan approval, the plan must be submitted on reproducible Mylar film.

CAD files may be requested after your project is approved

Typical Plan Elements:

Plans should be uncluttered and easy to read. Plans may be returned unchecked if the plan is difficult to interrupt the information. Improvement plans shall contain the following applicable items:

• Title Block - Indicating the The preparers name and contact information, Project name and description, Date of preparation, Case information (ie. Design Review number) (Sample)
• North Arrow
• Scale and Graphic Scale
• Vicinity Map of the projects location

Title Block:

We prefer that the design professional uses their own title block for projects in Cathedral City. This helps with identifying who the plan preparer is. Provide a location on the plans for final approval signature from the city. Depending on the type of plan, different signature blocks should be used.

For projects that require signature from our City Engineer, use the following information (Street Improvements; Sewer; Water; Storm Drain; Traffic Signal and Striping):

APPROVED FOR PERMITTING PURPOSES ONLY:  ARMANDO J. GARCIA BALDIZZONE, PE - CITY ENGINEER R.C.E. 70102

Projects that do NOT require the City Engineers' signature, use the following information (Grading Plans):

APPROVED FOR PERMITTING PURPOSES ONLY: CITY OF CATHEDRAL CITY

Construction Notes:

All plans must include notes describing key factors of your project. The following notes must be used on the appropriate plans and the issue date must be indicated on the plan.

• Erosion & Sediment Control Notes -
• General Notes (Effective October 4, 2024)
• Grading Notes (Effective July 1, 2018)
• Paving Notes (Effective October 4, 2024)
• Signing & Striping Notes

Welcome to the Engineering Departments Standards Online! Here you will find standard drawings for public works construction projects. The City of Cathedral City has adopted the County of Riverside County Road Improvement Standards and Specifications, ordinance No. 461 as the "City's Standards". Along with the County Standards, the City has several "City" standards and at time references the Caltrans Standard Drawings  and the Green Book.

• Riverside County Roadway Improvement Standards and Specifications 
  (Adopted City Standards)
• Caltrans 2006 Standard Plans (U.S. Customary units) 
• Curb Ramp Standard (Caltrans Std. A88A to be used for all off-site curb ramps)
• Driveway Approach Section 200-A
• Driveway Approach Section 200-B (Commercial)
• Dry Well Standard
• Curbside Mailbox Standard
• Utility Trench Pavement Replacement

Under the provisions of the federal Clean Water Act (CWA) (33 U.S.C. § 1251 et seq.) the National Pollutant Discharge Elimination System (NPDES) was created by the United States Environmental Protection Agency (US EPA) and together with the provisions of the California Water Code (CWC) (commencing with section 13000), a Water Quality Management Plan is required for priority projects listed below.

NPDES regulates the discharges of Potential Pollutants and Non-Stormwater discharges, minimize urban runoff from impacting receiving waters to the Maximum Extent Practicable (MEP).

On June 15, 2009 the amended Water Quality Management Plan (WQMP), which is part of NPDES became effective and requires on the following Private and Public Developments:

• SF hillside residence; impervious area ≥ 10,000 sq. ft.; Slope ≥ 25%
• SF hillside residence; impervious area ≥ 10,000 sq. ft.; Slope ≥ 10% & erosive soils
• Commercial or Industrial ≥ 100,000 sq. ft.
• Automotive repair shop
• Retail Gasoline Outlet disturbing > 5,000 sq. ft.
• Restaurant disturbing > 5,000 sq. ft.
• Home subdivision ≥ 10 housing units
• Parking lot ≥ 5,000 sq. ft. or ≥ 25 parking spaces

These Priority Development Projects require a Preliminary WQMP to be submitted to the City of Cathedral City upon application of project and Project-Specific WQMP (final) prior to approval of Grading Plan.
