Protecting resources through environmentally sound development
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 ManualCastle Rock Water recognizes the importance of sound stormwater planning and management. Stormwater management is an integral part of overall development planning and site design, which must be addressed in the earliest planning stages. All drainage reports and plans, drainage system analyses, and drainage system designs, submitted as a requirement of the Town of Castle Rock Public Works Regulations, shall comply with the criteria in the Storm Drainage Design and Technical Criteria Manual.
Drainageway Master PlansCastle Rock Water has completed 20 major drainageway watershed master plans. These master plans serve as supplemental documentation to the Stormwater Master Plan. The plans were developed by engineering consultants and follow the basic outline set forth by the Urban Drainage and Flood Control District. The purpose of the drainageway master plans is to determine the drainage, flooding and erosion problems within the individual watersheds and identify strategies to minimize or eliminate these problems. They also identify existing problems along the major drainageway system, analyze floodplain characteristics, and provide recommended improvements for flood conveyance, stream stabilization and water quality. The plans provide a guide for managing necessary drainageway improvements in an efficient manner as development occurs in the watersheds, and minimize costs to rate payers.
Executive summaries and conceptual design drawings of the drainageway master plans can be viewed through the links below. If you would like to view any of these drainageway master plans in their entirety, please email us your request.
Water Master PlanThe Water Master Plan outlines general planning for expansion and optimization of the Castle Rock water system necessary to meet the evolving water needs of the local community. The following principles serve as the base for the Town's water programs:
- Protect people, property and the environment
- Plan for the future
- Encourage coordination of infrastructure needs
- Operate the water enterprise fund as a business, balancing revenue and expenses
- Provide for effective long-term operation and maintenance of water system facilities
- Ensure water planning is consistent with, and considered part of, a fully integrated total water management approach
Water Facilities Master Plan
The Water Facilities Master Plan was adopted in 2006. 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
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.

- Pipe Delivery & Protection - Careful timing of deliveries and protecting the pipe from sediment and contaminants can reduce flushing and increase positive Bacteriological Testing results.
- 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 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
- 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

Drought Management PlanThe Drought Management Plan identifies the actions needed to ensure an uninterrupted supply of water when a drought-induced water supply shortage exists. The plan identifies specific values of a drought that will trigger management response.
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.
The Source Water Protection Plan helps the Town ensure clean and high-quality drinking water sources for current and future generations. The Plan is designed to:
Source Water Protection Plan
- Create an awareness of the community’s drinking water sources and the potential risks to surface water and/or groundwater quality within the watershed.
- Encourage education and voluntary solutions to alleviate pollution risks.
- Promote management practices to protect and enhance the drinking water supply.
- Provide for a comprehensive action plan in case of an emergency that threatens or disrupts the community water supply.
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.
