SUMMARY: The Cities of Pacific Grove, Carmel-By-The-Sea, and Seaside have discussed local water supply initiatives of their own. In addition to creating additional water supply, such local projects would likely provide some leverage in future discussions with the SWRCB in discussing changes to the CDO even if the desalination project is delayed.

RECOMMENDATION: The Committee should discuss whether the District should allocate some portion of the annual Water Supply Charge to help seed such projects. It should also be discussed whether such aid should be in the form of grants or loans, and whether or not the District should ask for an allocation of any water created. The Ordinance 152 Oversight Panel’s consensus was that the District should make it a priority to allocate some moneys for local projects and that reimbursement from the permanent financing of such projects, if any, would be better than outright grants. The panel did not support allocating a portion of the water created to the District as a reserve.

DISCUSSION: The City of Pacific Grove (City) has a shortage of potable water for domestic residential and commercial uses. The City currently uses approximately 100 to 125 acre-feet per year (AFY) of potable water for irrigation of the Pacific Grove Municipal Golf Links and the adjacent El Carmelo Cemetery. Additional potable water is used for public irrigation in other areas throughout the city and in nearby areas, including the Presidio of Monterey. Replacement of this irrigation demand with non-potable supplies will create a new offset of at least 100 to 125 AFY of potable water per project, for use by California American Water in meeting its obligations to find a replacement to its use of water from the Carmel River.

The proposed projects can be expanded beyond this capacity to meet other local non-potable demands or can be combined with each other to provide expanded benefits.

The following three Pacific Grove projects are proposed:

· Project 1: Pacific Grove Satellite Recycled Water Treatment Project. A new satellite recycled water treatment facility will be constructed at the former Point Pinos Wastewater Treatment Plant and deliver recycled water to irrigation sites throughout the City. Raw wastewater will be captured and diverted from the City’s sanitary sewer Basin 1 and conveyed to the new satellite recycled water treatment plant via 1,100 lineal feet of new 8-inch diameter sewer pipeline constructed within the golf links. Approximately 1,300 lineal feet of new 12-inch diameter recycled water pipeline will be constructed to deliver water to the golf links, cemetery, and other irrigation demands. Costs of water are between $2,624 and $3,042/AF, depending on the final annual volume of water produced.

· Project 2: Pacific Grove Recycled Water Project. Recycled water will be obtained from the Pebble Beach Community Services District (PBCSD). Raw wastewater from 500 homes in the Del Monte Park area of Pacific Grove will be captured and diverted to the existing Carmel Area Wastewater District (CAWD) reclamation facility for treatment. The wastewater diversion will flow through the existing wastewater collection system owned by the PBCSD. Recycled water from CAWD will be stored in the Forest Lake Reservoir and returned to the City through existing CAWD and PBCSD recycled water systems to a delivery point near the Spanish Bay Golf Course in Pebble Beach. Approximately 10,000 to 13,500 lineal feet of new 12-inch diameter recycled water pipeline will be required to be constructed to deliver water to the golf links, cemetery and other irrigation demands. Costs of water are $2,105/AF produced.

· Project 3: Pacific Grove Storm Water Recycling Project. Storm water from the City’s Congress Avenue or Greenwood Park Storm Drain Watersheds will be retained during the fall-winter wet period to be recycled to meet irrigation demands during the spring-summer season. Storm water will be diverted from the Congress Avenue or Greenwood Park storm drainage systems in a new storm water diversion structure, treated to remove trash and debris, and pumped to storage. A new 15-million gallon (MG) concrete reservoir or open storage reservoir will be constructed at the California American Water Company’s David Avenue property. The storm water will be treated to meet aesthetic requirements and to comply with Title 22 Regulations for irrigation with non-potable water. Treatment will include a constructed wetland, microfiltration, ultraviolet radiation, and disinfection. Approximately 8,800 lineal feet of new 12-inch diameter recycled water pipeline will be required to deliver water to the golf links, cemetery irrigation and other irrigation demands. Costs of water are $8,977/AF, depending on the final annual volume of water produced.

A letter from the City of Pacific Grove is attached as Exhibit 4-A.

The City of Carmel has discussed perennial springs under the Harrison Memorial Library to irrigate Devendorf Park in order to free up potable water. There is also the Del Mar Avenue perennial spring. The City has also recently entered into a recycled water purchase agreement with the District for approximately 0.5 acre-feet per year of Reclamation Project water and desires to investigate additional uses up to 5 acre feet per year.

The City of Seaside has determined that it has an approximately 110 acre-foot per year shortfall in its needs for the Seaside municipal water system as a result of the basin adjudication. City staff have approached the District for help in identifying replacement supplies.
