Irrigation/Landscape Plan Submittal Requirements

When is an Irrigation and Landscape Plan Review required?

In order to extend the yield of Denver Water’s water supply, and to encourage the efficient use of water, an Irrigation and Landscape Plan Review is required on all taps supplying 1 acre or more of irrigated/landscaped property or a green roof

Please note: A separate irrigation tap may be required if the property contains 1 acre or more, contiguous or non-contiguous, of irrigable area.

Irrigation/Landscape Designer submits the following:

  1. Signed Irrigation/Landscape Plan Acceptance Checklist.
  2. Full-sized set of irrigation and landscape multi-sheet PDFs.
  3. Fully executed Water Budget. Average Precipitation and Effective Precipitation can be used by designers to relay typical irrigation use to their clients. Designers should utilize zero (0) Average Precipitation to account for drought scenarios to ensure the system can deliver adequate water and protect the survival of plant material.
  4. Payment of $450 plan review fee is required. (Plans that require more than three formal submittals will be subject to an additional $450 plan review fee).

Note: All taps to 24-inch and larger water mains require the developer’s engineer and contractor to design and perform the work to support their project.

If the tap size is 3-inches or larger, Denver Water will require a separate Water Plan Submittal.

Step-By-Step Process for Irrigation/Landscape Plan Review

The following steps will guide you through the Irrigation/Landscape Plan Review process.

Note: Designs are not limited to these steps.

Step 1: Initiate Formal Irrigation and Landscape Plan Review Submittal Package

  1. Send an email to WaterSalesPlanReview@Denverwater.org requesting to initiate Denver Water’s Irrigation and Landscape plan review process. The irrigation and landscape designer shall create a Dropbox folder and share the Dropbox folder containing the following items:
    1. Signed Irrigation/Landscape Plan Acceptance Checklist.
    2. Full-sized set of irrigation and landscape multi-sheet PDFs.
    3. Fully executed Water Budget. Average Precipitation and Effective Precipitation can be used by designers to relay typical irrigation use to their clients. Designers should utilize zero (0) Average Precipitation to account for drought scenarios to ensure the system can deliver adequate water and protect the survival of plant material.

Step 2: What to Expect

  1. The Irrigation and Landscape Designer can expect to receive an email response from Water Sales with confirmation of the assigned Plan Review Coordinator within 2-3 business days.
  2. If the Irrigation and Landscape Plan Review package is incomplete and/or missing checklist items, an email notification will be sent to the Irrigation and Landscape Designer within 2-3 business days informing of the missing items. The Irrigation and Landscape Designer will then be required to resubmit a new Irrigation and Landscape Plan Review package. 
  3. If the Irrigation and Landscape Plan Review package is complete, the Plan Review Coordinator will initiate the Plan Review process and prepare the Plan Review Fee invoice for collection of payment.
  4. The Irrigation and Landscape Designer should plan for 5-7 business days for the initial review period. 
  5. The Plan Review Coordinator will forward the redline markups and written responses back to the Irrigation and Landscape Designer via Dropbox.

Step 3: Subsequent Irrigation/Landscape Plan Review Submittals

  1. If the design is not approved, the Irrigation and Landscape Designer must submit a full set of revised Irrigation and Landscape Plans and a Comment Response Letter.
  2. This process is repeated until the design is approved by Denver Water.
  3. Plans that require more than three formal submittals will be subject to an additional $450 Plan Review Fee.

Step 4: Final Irrigation/Landscape Plan Approval

  1. The Plan Review Coordinator will forward the approved Irrigation and Landscape PDFs and approval letter to the Irrigation and Landscape Designer via Dropbox.
  2. Applicant must complete an application for Water Supply License and pay applicable fees to Denver Water for all domestic/irrigation taps, separate from the Irrigation and Landscape plan review process.
  3. Quotes can be obtained by emailing a Denver Water Taps Sales team member at WaterSales@denverwater.org.
  4. If the tap is located outside of the City and County of Denver, the applicant must initiate the application process with the applicable water district.
  5. In cases where non-potable water is considered, the applicant must provide the User Plan to Comply and Notice of Authorization with the Application for Water Supply License and payment.

If nonpotable water is being considered for irrigation purposes, a User Plan to Comply must be submitted and approved by the Colorado Department of Public Health and Environment. The applicant must provide the executed User Plan to Comply and Notice of Authorization with the License Application and payment before Denver Water will install the meter. Expect at least nine months processing time for the Colorado Department of Public Health and Environment to review and approve the plan.
