Flood protection measures for local drainage shall comply with California Drainage Law and provide that stormwater flows are received onto and discharged from this property in a manner that is reasonably compatible with predevelopment conditions. The City of La Quinta (City) shall require mitigation measures to be incorporated into the development to prevent flooding of the site or downstream properties. These measures shall require 100 percent on -site retention of the incremental increase of runoff from the 100-year storm. The project is located within the service area of Coachella Valley Water District (CVWD) for the provision of domestic water and sanitation service. The initiation of said service to this area will be subject to the satisfaction of terms and conditions established by CVWD and imposed from time to time, including but not limited to fees and charges, water conservation measures, etc. CVWD may need additional facilities to provide for the orderly expansion of its domestic water and sanitation systems. These facilities may include pipelines, wells, reservoirs, booster pumping stations, lift stations, treatment plants and other facilities. The developer may be required to construct/install these facilities and then convey said facilities to CVWD along with the land and/or easements on which these facilities will be located. The terms and conditions for the planning, design, construction/installation, and conveyance of property interests shall be determined by CVWD pursuant to its rules and regulations as said requirements may be revised from time to time. These sites shall be shown on the tract map as lots and/or easements to be deeded to CVWD for "CVWD public services" purposes. Coachella Valley Water District P.O.

Unless or until all requirements for the initiation of service are met, the developer shall not be deemed to have any vested right or other commitment to receive water and/or sanitation service. In the event all of the terms, conditions, fees and charges are not satisfied on or before the expiration date, this notice shall expire. Upon expiration, the developer will be required to submit a new application and otherwise comply with any and all new or amended requirements for the provision of service as may be determined by CVWD pursuant to its rules and regulations. Domestic water and sanitation service remains at all times subject to changes in regulations adopted by CVWD's Board of Directors including reductions in, or suspensions of, service.

Dry or wet sewers shall be installed as determined by CVWD. Plans and designs for installation of the facilities required by CVWD shall be submitted to and approved by CVWD prior to issuance of a building permit. There are existing United States Bureau of Reclamation (USBR) facilities not shown on the development plans. There may be conflicts with these facilities. The City shall withhold issuance of grading permits until CVWD has reviewed the proposed development and related impacts to the USBR facilities and associated right-of-way and provided the City with written confirmation that there is no interference. The USBR conflicts include but are not limited to Irrigation Lateral 123.45, 123.45-1.3, 123.45-0.75, 123.45-0.75-0.5, 123.45-0.75-0.8, and 123.45-0.75-1.0. The project lies within the East Whitewater River Subbasin Area of Benefit. Groundwater production within the area of benefit is subject to a replenishment assessment in accordance with the State Water Code. All water wells owned or operated by an entity producing more than 25 acre-feet of water during any year must be equipped with a water -measuring device. A CVWD Water Production Metering Agreement is required to provide CVWD staff with the authority to regularly read and maintain this water -measuring device. This development lies within the study area of the 2010 Water Management Plan Update The groundwater basin in the Coachella Valley is in a state of overdraft. Each new development contributes incrementally to the overdraft. CVWD has a Water Management Plan in place to reduce the overdraft to the groundwater basin. The elements of the Water Management Plan include supplemental imported water, source substitution and water conservation. The plan lists specific actions for reducing overdraft. The elements and actions described in the plan shall be incorporated into the design of this development to reduce its negative impact on the Coachella Valley groundwater basin.
