KLEINFELDER savings between standard and conservative water use programs, as a means of demonstrating water conservation efforts at the development. The Integrated Water Management Plan (IWMP) will have a goal of providing a document that addresses the use and management of all water for the development, emphasizing conservation, re-use and good management practices. Several objectives are critical for the IWMP, as follows: • Identification of Operational Water Demand to support the development. The OWD will describe the quantities of water needed to support the various uses of water on-site. Furthermore, the OWD will describe the quality needed for each demand (e.g. non-potable for certain irrigation needs, potable for domestic and culinary). Finally, the OWD will describe the source or sources of each water type. • Discussion of how water will be managed on the development, and how these uses will be integrated with the overall project. For example, much of the irrigation water for non-residential "green areas" (i.e. parks, medians, etc.) may come from the lake features planned for the development. The water to replenish these lake features may be shallow non-potable groundwater, or it may be surface water from an off-site source, ear-marked for groundwater recharge. • Support for the Environmental Impact Report. The first "edition" of the IWMP needs to support the EIR for the project. That support will be in the form of a generalized description of the amount of planned water use on site, the source for this water, and how these waters will be integrated to increase conservation and re-use. • Support for operational planning. The next "edition" of the IWMP will be an expanded assessment of the source water for the facility, along with more detailed planning regarding how water will be delivered, moved, and re-used on the facility. This will facilitate planning as the project develops. Additionally, this will be useful for integrating with the SB221 planning that the City of Stockton intends to complete after the SB610 Water Supply Assessment is accepted. • Support for Proiect Implementation. The final "edition" of the IWMP will include all of the above information, along with detailed descriptions of water use per phase, water monitoring and testing throughout the development, and water use reporting. In this final edition, the actual management mechanism for water should be discussed, along with long-term monitoring and reporting of water use, re-use, and quality. Key components of our work are as follows: • Identify all sources of water, potable and non-potable that are available to the Mariposa Lakes Development (Project). 02001 PROP.ENv/ST05P346R/JDZ:ly Page 7 of 12 ©2005 Kleinfelder, Inc.
