Castle Rock implements water management strategy for new development project

The Castle Rock Planning Commission convened on April 24, 2025, to discuss critical developments related to water supply and management for upcoming residential projects. The meeting focused on the integration of agricultural water resources into the town's water system and the implications for future growth.

The discussion began with a review of the water resources available for a new development, which includes 757 acre-feet of groundwater. This water will be used primarily for residential purposes, while an additional 106 acre-feet is designated for agricultural use, specifically for watering parks. Mark Marlowe, a representative from the town's water department, emphasized the importance of adhering to water efficiency standards as part of the development process.

Marlowe clarified that the developers would be required to pay full system development fees for renewable water supplies, which is crucial for the long-term sustainability of the town's water resources. He noted that the town has planned for this development for over two decades, indicating that it is not a new or unexpected addition to the community's growth strategy.

The conversation also addressed the potential impact of the development on existing groundwater resources. Marlowe assured the commission that the town aims to minimize reliance on groundwater, using it primarily as a drought supply. He explained that the water rights being brought into the system would help mitigate any adverse effects on adjacent wells, ensuring that the development aligns with the town's water management goals.

In addition to water supply, the commission discussed the importance of stormwater management. Marlowe highlighted that stormwater runoff from the new development would affect the town's existing stormwater systems. Developers will be expected to meet the town's stormwater standards and contribute to impact fees, which will support larger infrastructure projects, such as improvements along East Plum Creek.

The meeting concluded with a consensus on the necessity of integrating these developments into Castle Rock's existing water and sanitation systems, ensuring that both current and future needs are met effectively. The commission plans to continue monitoring the progress of these developments as they move forward.
