California Code, Water Code - WAT § 12956

(a) The increased operating expenses necessitated by population increase within the impact area for maintenance of police and fire protection, public hospitals, public health and sanitation and such other activities as may be approved by the Department of Finance and the Department of Water Resources at the same level of service as prevailed within or for the impact area prior to the start of the construction. A subsequent increase in the level of a specific service may be approved by the State Department of Finance. Level of service shall be measured by the ratio of personnel or facilities serving the impact area to the total population within the same area. The portion of the construction-generated population expected to reside within the impact area shall be estimated by the Department of Water Resources for each fiscal year in which the State provides financial assistance under this part to any governmental agency.

(b) Seventy-five percent of the increased cost to the county of emergency and indigent relief provided by the county under the provisions of Chapter 2 (commencing at Section 2500) of Division 4 of the Welfare and Institutions Code 1 at standards that existed prior to the start of construction. An increase in such standards may be approved by the State Department of Finance. The State will also pay all necessary increased costs resulting from personnel, office, and automobile expenses created by an increase in the emergency and indigent caseload, as determined by the Department of Finance.
