Mountain House Specific Plan III — ........................................................................................................................................................................... 16.2.2.3 Storm Drains Storm drainage and flood protection facilities will be constructed at the same time as the streets and other major infrastructure and will be maintained by the MHCSD. A maintenance and operation plan for the detention basin and flood protection facilities shall be prepared and accepted by the MHCSD prior to the approval of the first final map in Neighborhood A/B. Maintenance personnel,vehicles,and equipment may be shared with other facility maintenance crews to achieve staffing efficiency and cost reductions. These maintenance costs have been incorporated in the fiscal analysis presented in the PFP and the MHCSD Fiscal Analysis. 16.2.2.4 Energy and Communications _ Electrical power distribution will be installed on an as-needed basis as part of the on-site roadways. The initial service line extensions will require accelerated planning and construction to coincide with the start — of residential development. Natural gas will also be provided on an as-needed basis as part of the on-site roadways. However,the relocation of the existing gas line from Mountain House Parkway to Central Parkway will require detailed planning and phasing. Telecommunications will also be provided on an as-needed basis and will be developed along with on-site roadways. 16.2.2.5 Potable Water The water treatment plant(WTP)north of Byron Road will be expanded to accommodate the projected _ demand of development within the planning areas of Specific Plans II and III. The existing WTP has a capacity of 3.0 mgd, and at full build-out will have a capacity of between 17.1 mgd and 20 mgd. One or two more phased expansions will be needed to bring the plant to its planned full buildout capacity. Storage tanks are assumed to be phased in three increments after the first Specific Plan. Water storage tanks for both Zones I and 11 will be required to be constructed as part of the Specific Plan HI development. The proposed tank site location alternatives are depicted on Figure 12.1. 16.2.2.6 Wastewater The Waste Water Treatment Plant(W WTP)north of Byron Road will be expanded to accommodate the projected demand of development within the planning areas of Specific Plans II and 111. The present W WTP has a treatment capacity of 0.45 MGD and is currently being enlarged to a capacity of 3.0 MGD. In order to accommodate development within Specific Plan II and III, the engineering design process for the second expansion is now beginning. It is planned that by early 2006, the W WTP will have the capacity to treat 5.4 MGD of wastewater, its planned buildout capacity under the Master Plan.
