Plans and Regulations

Protecting resources through environmentally sound development


The Town is committed to protecting water resources and ensuring future development continues in an environmentally sound manner. Below is a list of plans, regulations and manuals to assist in these efforts:

Stormwater

Grading, Erosion and Sediment Control & Drainage Erosion and Sediment Control Manual (GESC / DESC)


The GESC and DESC Manual (commonly known as the GESC Manual) describes the permitting programs that have been adopted to promote environmentally sound construction practices in Town. The goal of the program is to implement erosion and sediment control best management practices as a standard for all land-disturbance activities. The hope is to reduce increases in erosion and sedimentation over pre-development conditions. Erosion caused by construction and downstream sedimentation can damage property and degrade the quality of streams and lakes. The GESC and DESC Manual is a large document so it may take several minutes to open the full manual. However, for easier viewing the document has been broken out chapter-by-chapter on the GESC and DESC Manual web page.

Storm Drainage Design and Technical Criteria Manual 


The Stormwater Drainage Design and Technical Criteria Manual was adopted in 2007. The manual presents the policies and minimum technical criteria for the planning, analysis and design of storm drainage systems within Town boundaries. The manual was developed in cooperation with Douglas County and urban drainage to improve consistency between neighboring jurisdictions. 

Stormwater Master Plan


The Stormwater Master Plan was adopted in 2004 and updated in 2010. The plan commits the Town to a long-term program to ensure drainage and other systems control stormwater runoff, protect the public during major storms, protect property values, safeguard Town streams from the high level of pollutants carried by urban runoff, and balance storm drainage planning approaches to complement open space and recreation corridors.

The plan outlines stormwater and floodplain problem areas and recommends time frames and priorities for specific drainageway improvement projects through 2020. The prioritization and ranking of these capital improvement projects were based on an evaluation 
that included criteria such as property protection, public safety, flood risk and water quality enhancement. 

Water

Water Facilities Master Plan 


The Water Facilities Master Plan was adopted in 2006 and updated in 2010. The plan examines the existing water system infrastructure. 
It identifies water treatment and distribution capital improvement projects required to provide service to existing and future development through build-out of the Town’s service area boundary. Specifically, the plan examines the following components of the water supply system:

  • Existing water treatment and distribution system
  • Potable water demands and finished water capacity
  • Water treatment for meeting existing and future demands
  • Water distribution system modeling for both existing and future conditions
  • Recommended capital improvements for maintaining a safe reliable drinking water system
The Water Facilities Master Plan is not available electronically; however, you can view a copy at Castle Rock Water.

Water System Design Criteria Manual


The Water System Design Criteria Manual contain the polices and minimum technical criteria for the planning, analysis and design of potable water systems in the Town, as well as areas served by the Town. The manuals outline requirements for utility reports and plans, analyses and designs. The primary goal of the new manuals is to bring criteria up to current construction and design standards. The most significant change to the criteria is aligning the manuals with the new development procedures, which moves detail to the back end of the process.

Construction Methodology and Materials Manual


In order to help our contractors work quickly and efficiently, we've put together this quick reference guide with links that will take you directly to specific sections in The Construction Methodology and Materials Manual. This manual gives contractors in-depth information on how to construction water mains. These procedures protect the Town's drinking water supply.

  • Testing Procedures - There are tests required before the new main can be connected to the Town's Distribution System. These tests are: High Chlorine, Low Chlorine, Hydro static and Bacteriological Tests, in that order. These tests shall be performed and witnessed by the Development Inspector.
  • Acceptance of Pipe - The new pipeline system may be placed in operation after all required cleaning, testing and inspections have been completed and written permission has been granted by the Castle Rock Water Supervisor. Please refer to Policy and Procedures 1.2.5 in The Construction Methodology and Materials Manual.
Wastewater

Wastewater Master Plan 


The Wastewater Master Plan was adopted in 2004 and updated in 2010 and 2016. The plan examines the existing wastewater system infrastructure. It identifies collection system capital improvement projects required to provide service to existing and future development through build-out of the Town’s service area boundary. The goals of the plan are to: 

Identify collection system deficiencies and/or future facility requirements.
Develop tools to update the plan as growth conditions change or new development occurs.
Develop a plan for recommended projects that balances infrastructure requirements with fiscal responsibility.
Develop cost estimates as a basis for input into the annual rates and fee analyses.

Wastewater Collection Design Criteria Manual

The Wastewater Collection Design Criteria Manual contain the polices and minimum technical criteria for the planning, analysis and design of wastewater-collection systems in the Town, as well as areas served by the Town. The manuals outline requirements for utility reports and plans, analyses and designs. The primary goal of the new manuals is to bring criteria up to current construction and design standards. The most significant change to the criteria is aligning the manuals with the new development procedures, which moves detail to the back end of the process.

Water Resources / Conservation  

Landscape and Irrigation Performance Standards and Criteria Manual


The Landscaping and Irrigation Performance Standards and Criteria Manual (Landscape Manual) outlines the policies, procedures, performance standards and minimum criteria. The criteria provide comprehensive water-efficient design, installation and maintenance standards in a manner that balances quality of life with the overall responsibilities of the Town as a water provider. The manual demonstrates the Town's commitment to the wise use of water resources. It enhances regional characteristics; promotes environmental sustainability; and ensures land use compatibility in a practical, consistent and efficient administrative environment.


Water Efficiency Master Plan 


The Water Efficiency Master Plan approved by Town Council on July 21, 2015 (Resolution 2015-62) outlines a goal-oriented, performance-based and cost-effective strategy that provides a practical approach to design and implementation, while providing measurable water savings. This plan outlines current and future water-use profiles, establishes conservation goals, identifies conservation measures, reflects the costs and benefits of conservation, defines regulations and incentives, outlines the water budget rate structure and educational program, and establishes evaluation processes. The plan was revised in February 2016 to address minor comments received from the State of Colorado Water Conservation Board. 

Water Resources Strategic Master Plan 


The Water Resources Strategic Master Plan was adopted in 2006, updated in 2010, and revised in 2016. This plan addresses the future water needs for the Town to achieve a sustainable long-term water supply. The plan charts the path and identifies strategies for the Town to move toward a sustainable water future. 

Currently, a large percent of the Town's water demands are met by deep aquifer groundwater. Over the past several years, water providers, community leaders and the public have noted declining water levels throughout the region, including in Castle Rock. With or without growth, that existing groundwater supply is a non-renewing resource that is not sustainable for the Town's long-term future. 

Water Use Management Plan

The Water Use Management Plan is designed as a demand-management tool to allow adequate volumes and pressures to the water distribution system during landscape irrigation season. This program is also intended to encourage wise use of a finite resource.
