• Fire Department approved hydrant locations and fire flow requirements (flowrate and duration)
• Street improvement plans, sanitary sewer and storm drain plan and profile (if no profiles, must have flow line and finish grade elevations on plan view to calculate crossings), and grading plan;
• CAD drawing file
• Meter Sizing Form for each service larger than 1”
• Fire Sprinkler Calculations (if metered service is combination domestic and fire)
• Tentative Parcel/Subdivision/Tract Map
• Initial Deposit of $10,000 for small main extensions or $20,000 for larger main extensions or subdivision projects.

Once all project requirements are received and verified complete (including the initial deposit), Cal Water will begin the design process. Outside firms are not allowed to perform water main design, so all design will be performed by Cal Water or an agent of Cal Water. Estimated turnaround time for completed design is 45 days. Any back and forth between the Applicant and Cal Water will stop the design clock, which will only resumed after the issue is resolved. The final design of the water main will be determined by Cal Water and will adhere to the Cal Water’s design standards.

Typical design criteria include, but are not limited to the following:

• All 12” and larger piping is Ductile Iron Class 350
• Nominal cover Is 4’, absolute minimum is 2.5’
• Minimum clearance between utilities is 1’ wall to wall
• Cal Water does not install non-standard main sizes (4”, 10”, etc.)
• All applicable separation standards as set forth in Section 64572, Title 22, Chapter 16 of CCR must be observed
  • Alternatively, upgraded material will be required pending approval from the State Waterboard, Division of Drinking Water (DDW)
• Fire Services (FS) shall not be looped to have two points of connection to the Cal Water’s distribution system
• Surge tanks may be required if the use of private domestic or fire pumps are employed
• An updated Fire Flow Test may be required to properly size and determine facility needs
• Proof of conformance with SB 7 (if applicable).

Please note that Cal Water reserves the right to make all final design decisions

CWC § 10910 (a)

Any city or county that determines that a project, as defined in Section 10912, is subject to the California Environmental Quality Act (Division 13 (commencing with Section 21000) of the Public Resources Code) under Section 21080 of the Public Resources Code shall comply with this part.

CWC § 10912

For the purposes of this part, the following terms have the following meanings:

(a) “Project” means any of the following:

(1) A proposed residential development of more than 500 dwelling units.

(2) A proposed shopping center or business establishment employing more than 1,000 persons or having more than 500,000 square feet of floor space.

(3) A proposed commercial office building employing more than 1,000 persons or having more than 250,000 square feet of floor space.

(4) A proposed hotel or motel, or both, having more than 500 rooms.

(5) A proposed industrial, manufacturing, or processing plant, or industrial park planned to house more than 1,000 persons, occupying more than 40 acres of land, or having more than 650,000 square feet of floor area.

(6) A mixed-use project that includes one or more of the projects specified in this subdivision.

(7) A project that would demand an amount of water equivalent to, or greater than, the amount of water required by a 500 dwelling unit project.

(b) If a public water system has fewer than 5,000 service connections, then “project” means any proposed residential, business, commercial, hotel or motel, or industrial development that would account for an increase of 10 percent or more in the number of the public water system’s existing service connections, or a mixed-use project that would demand an amount of water equivalent to, or greater than, the amount of water required by residential development that would represent an increase of 10 percent or more in the number of the public water system’s existing service connections.

CWC § 10910 (b)

The city or county, at the time that it determines whether an environmental impact report, a negative declaration, or a mitigated negative declaration is required for any project subject to the California Environmental Quality Act pursuant to Section 21080.1 of the Public Resources Code, shall identify any water system that is, or may become as a result of supplying water to the project identified pursuant to this subdivision, a public water system, as defined in Section 10912, that may supply water for the project. If the city or county is not able to identify any public water system that may supply water for the project, the city or county shall prepare the water assessment required by this part after consulting with any entity serving domestic water supplies whose service area includes the project site, the local agency formation commission, and any public water system adjacent to the project site.

CWC § 10910 (c) (4)

If the city or county is required to comply with this part pursuant to subdivision (b), the water supply assessment for the project shall include a discussion with regard to whether the total projected water supplies, determined to be available by the city or county for the project during normal, single dry, and multiple dry water years during a 20-year projection, will meet the projected water demand associated with the proposed project, in addition to existing and planned future uses, including agricultural and manufacturing uses.

CWC § 10911

(b) The city or county shall include the water supply assessment provided pursuant to Section 10910, and any information provided pursuant to subdivision (a), in any environmental document prepared for the project pursuant to Division 13 (commencing with Section 21000) of the Public Resources Code.

(c) The city or county may include in any environmental document an evaluation of any information included in that environmental document provided pursuant to subdivision (b). The city or county shall determine, based on the entire record, whether projected water supplies will be sufficient to satisfy the demands of the project, in addition to existing and planned future uses. If the city or county determines that water supplies will not be sufficient, the city or county shall include that determination in its findings for the project.
