Sacramento County Zoning Code § 905-07 Dedications

A. The Floodplain Administrator may impose, as a condition for the granting of a permit, the requirement of dedication or irrevocable offer of dedication of real property within the property for which the approval is sought, for drainage, floodplain, or floodway easements. Such dedication requirement must be reasonably related to the public needs arising as a result of the development.
B. The Floodplain Administrator may impose, as a condition for the granting of a permit, the requirement for the construction of drainage and flood control facilities. Such construction requirements must be reasonably related to the public needs arising as a result of the development.
C. Where the Floodplain Administrator has imposed a condition requiring the permittee to construct or install offsite improvements on land in which neither the permittee nor the County has sufficient title or interest, including an easement or license, at the time the permit application is filed with the County, to allow the improvements to be made, the permittee shall make a good faith effort to acquire by negotiation an interest in land which will allow the improvements to be made. If the permittee is unable to acquire such an interest in land, the permittee shall so notify the Floodplain Administrator, providing sufficient evidence of having made a good faith effort. The County shall have 120 days from receipt of such notice and sufficient evidence to acquire by negotiation or commence proceedings pursuant to ordinance 7 of Part 3 of the Code of Civil Procedure to acquire an interest in land which will permit the improvements to be made. If the County fails to meet this 120-day time limitation, the condition for construction of offsite improvements shall be conclusively deemed waived. The County may require the permittee to enter into an agreement to complete the improvements at such time as the County acquires an interest in the land which will allow the improvements to be made. Nothing in this section precludes the County from requiring the permittee to pay the cost of acquiring offsite real property interests required for such improvements.
