Rancho Colina Mobile Home Community Consolidation Evaluation

Rancho Colina Mobile Home Park (Rancho Colina) is a small, disadvantaged community just outside of Morro Bay. The community consists of 69 mobile homes and 57 RVs. Since Rancho Colina is isolated from nearby utilities, it relies upon a privately owned, small T1 wastewater treatment facility. The wastewater treatment facility is failing and its drinking water supply is contaminated with Nitrate. To address these challenges, the Regional Water Quality Control Board (RWQCB) is assisting Rancho Colina in evaluating of potential consolidation with the City of Morro Bay’s (City) water and wastewater systems.  

To support the consolidation ConfluenceES is working with the City and Rancho Colina to develop Clean Water State Revolving Fund’s (CWSRF) and Drinking Water State Revolving Fund (DWSRF) Grant Applications. The grants will pay for a feasibility study assessing the connection of Rancho Colina to the City’s water and wastewater system, planning, design, permitting and construction of the connection infrastructure, and construction of the necessary upgrades to the City’s water and wastewater systems to accommodate the consolidation. For this project, ConfluenceES assisted in developing the funding applications, which included developing maps, figures, cost estimates, schedules, and estimated budgets. Through the process of preparing the applications, ConfluenceES has been communicating extensively with City, Rancho Colina, RWQCB and funding agencies staff and gained familiarity with the complex application submittal process and requirements.
