Encinitas Municipal Code § 5.3 Water Service and Facilities

The site is served by two water districts, Olivenhain Municipal Water District and San Dieguito Water District. The district boundaries and existing and proposed facilities are illustrated in Figure 22, Water Plan. The exact boundaries of the two water districts are subject to change as planning for the Encinitas Ranch Specific Plan continues. Any changes that occur to district boundaries may necessitate a review of existing and planned infrastructure and may result in changes to the Water Plan for Encinitas Ranch. Changes to the Water Plan shall be reviewed and approved by the appropriate water agencies and the City of Encinitas.

5.3.1 EXISTING FACILITIES: OLIVENHAIN MUNICIPAL WATER DISTRICT¶

The following existing water lines and facilities are located in the vicinity of the Specific Plan Area and within the boundaries of the Olivenhain Municipal Water District (see Figure 22, Water Plan):

▪	10-inch water line in Quail Hollow Drive/Swallowtail Road.
▪	12-inch water line heading west from the existing Wanket reservoir.
▪	12-inch water line heading north from the existing Wanket reservoir.
▪	16-inch steel line gravity feed line from El Camino Real to the existing Wanket reservoir.
▪	16-inch water line from the existing Wanket reservoir to El Camino Real.
▪	12-inch water line in El Camino Real.
▪	10-inch water line in Via Cantebria.
▪	8-inch line in Rosebay Drive and Foxglove Street.

5.3.2 EXISTING FACILITIES: SAN DIEGUITO WATER DISTRICT¶

The following existing water lines and facilities are located in the vicinity of the Specific Plan Area and within the boundaries of the San Dieguito Water District (see Figure 22):

▪	16-inch water line heading south from the existing Wanket Reservoir.
▪	16-inch and 20-inch water lines southwest to Leucadia Boulevard from the existing Wanket Reservoir.
▪	14-inch water line heading south and southwest to Leucadia Boulevard from the existing Wanket Reservoir.
▪	10-inch water line in Sidonia Street.
▪	16-inch water line in Quail Gardens Drive.
▪	16-inch water line in Saxony Road.
▪	16-inch water line heading east from Quail Gardens Drive.

5.3.3 PROPOSED FACILITIES: OLIVENHAIN MUNICIPAL WATER DISTRICT¶

Off-site, the existing main in El Camino Real varies in size from 12-inches to 16-inches. A portion of this line between Garden View Road and Olivenhain Road exists as a 12-inch line; this portion of the line will need to be replaced by a 16-inch line as a result of the project. Another segment of this main, from Garden View Road south, also exists as a 12-inch line. A hydraulics study of the area's system must be performed to determine if that segment must be enlarged in order to adequately handle the anticipated flows. Portions of the project will be served by a water distribution system to be constructed concurrent with development of each Planning Area. Development plans for areas within the Olivenhain Municipal Water District boundaries shall be submitted to the district for hydraulic analysis so that pipe sizing can be determined at the time of final design of the water system.

Exceptions & meaning →

5.3.4 PROPOSED FACILITIES: SAN DIEGUITO WATER DISTRICT¶

A review of the San Dieguito Water District Water Master Plan, dated August 1990, has indicated a need for further capital improvements within the District to provide adequate water supply to existing and planned development within the District boundaries. The Master Plan groups these improvements into three project categories: high priority, medium priority, and low priority. The following project priorities are recommended by the Master Plan:

A. High Priority

•	Connection of the existing 16-inch line on Ecke Ridge to the existing 16-inch line in Via Cantebria.
•	Connection of the existing 16-inch line in Quail Gardens Drive to the existing 16-inch line in Leucadia Boulevard.
•	Construction of a new reservoir (Ecke Reservoir No. 1).

B. Medium Priority

There are no medium priority facilities required to serve the Encinitas Ranch project.

C. Low Priority

The following recommendation is based upon ultimate build-out figures according to the City of Encinitas General Plan:

•	Construction of a new distribution main from Via Cantebria to the Wanket Reservoir.

The San Dieguito Water District Water Master Plan also addresses treated water storage requirements, and indicates a deficiency in the present storage facilities. It recommends candidate sites for reservoir construction; two of which lie within the project boundary:

•	Ecke Reservoirs No.'s 1 (7.5 mg capacity) and 2 (3.0 - 8.0 mg capacity).
•	A second storage tank near the existing Wanket Reservoir is considered an optional site. However, if Ecke Reservoir No. 2 is constructed with sufficient capacity, this option will not be required.

These items are considered low priority by the San Dieguito Water District Water Master Plan.

The on-site development will be served by an internal water distribution system to be constructed concurrent with development within each Planning Area. Specific sizes and facilities shall be determined at the time of final design of the water system.

Exceptions & meaning →

5.3.5 RECLAIMED WATER¶

No reclaimed water facilities exist on-site within either water district. However, dual water systems will be required within the project with the reclaimed water systems fed by cross-tie connections to the potable water systems. These cross-ties will be removed when reclaimed water becomes available. The construction of the reclaimed water systems will be in accordance with the standards and specifications of the applicable water districts.

Exceptions & meaning →

5.3.6 EXISTING RESERVOIRS¶

Wanket reservoir, an existing three million gallon water storage facility, is located in the northeastern portion of the Specific Plan Area (Not-a-Part parcel). The reservoir is jointly owned by the Olivenhain Municipal Water District (OMWD) and the San Dieguito Water District (SDWD). The OMWD controls two-thirds of the reservoir capacity, and the SDWD controls the remaining third.
