The Board of Supervisors finds that the continued expansion of urban and agricultural-residential uses into the agriculturally zoned lands of Sacramento County ("County") that are identified through the California Environmental Quality Act ("CEQA") process or by appropriate regulatory agencies to provide suitable foraging habitat for the Swainson's Hawk, a listed threatened species under the California Endangered Species Act, will, absent mitigation, result in a significant reduction of such foraging habitat. The reduction in foraging habitat value can occur gradually or immediately through requests for zoning changes of agriculturally designated lands to agricultural zones that allow for smaller parcel size or through changes to agriculturally designated lands to an urban land use designation or through requests for land use entitlements for non-agricultural uses that are incompatible with the maintenance of Swainson's Hawk foraging habitat. Reduction in foraging habitat can also occur as the result of public projects or as the result of development on large undeveloped commercial and industrial lands. For any such projects on parcels which are within 10 miles of a Swainson's Hawk nest the Board of Supervisors desires to establish an additional means of mitigating for loss of Swainson's Hawk foraging habitat.
The Board of Supervisors has determined, in consultation with DFG, that suitable foraging habitat for the Swainson's Hawk exists in both established land conservation programs in Sacramento County which includes existing and potential foraging habitat for the Swainson's Hawk, and in agricultural and open lands currently not part of a conservation program. The Board of Supervisors finds that the most effective means of mitigation for the loss of suitable Swainson's Hawk foraging habitat is the direct preservation, in perpetuity, of equally suitable foraging habitat on an acre-per-acre basis based on the project's determined acreage impact. Such preservation should occur, pursuant to this chapter, prior to onset of development activities that cause the impact (i.e., land clearing and site grading) or the recordation of a final map, whichever occurs first, or the final adoption of a zoning ordinance if only a rezone was approved. Development project proponents should be responsible for locating and acquiring the appropriate land/or legal instruments (such as conservation easements) that will ensure the preservation of Swainson's Hawk foraging habitat in perpetuity. The Board of Supervisors also finds that it may be infeasible to mitigate for impacts to Swainson's Hawk foraging habitat by acquiring easements for less than 40 acres and proponents of projects determined to impact less than 40 acres should have the option to mitigate adverse impacts to Swainson's Hawk foraging habitat through the payment of an impact mitigation fee. An impact mitigation fee, as established pursuant to this chapter, will provide funds to acquire available land with suitable Swainson's Hawk foraging habitat values.
The Board of Supervisors recognizes that mitigation for foraging habitat for the Swainson's Hawk is only feasible when replacement habitat is provided within the known foraging area for the hawk. In order to provide adequate mitigation for the loss of Swainson's Hawk foraging habitat pursuant to CEQA, the acquisition of mitigation habitat either by procurement of a conservation easement or by fee title is necessary. Further, the Board of Supervisors deems it necessary to restrict the scope of possible mitigation sites to parcels that are located within the geographical foraging area of the Swainson's Hawk in the unincorporated County outside the Urban Services Boundary, and that are owned and/or managed by a conservation organization at locations that are acceptable to DFG. The Board of Supervisors also finds that due to limited opportunities for acquisition of mitigation lands in northern Sacramento County, that for those projects which are north of the American River only, there shall be added to the scope of possible mitigation sites, those properties in Sutter and Placer Counties which lie in the area defined by the Sacramento County Line to the south and Riego/Baseline Road to the north, bounded by the Sacramento River and Watt Avenue to the west and east respectively.
The Board further finds that the direct preservation of suitable Swainson's Hawk foraging habitat or the payment of an impact mitigation fee for the actual acquisition of such habitat, will meet the requirements of mitigation under CEQA by reducing the level of impact to Swainson's Hawk foraging habitat to a less than significant level for those parcels falling within the scope of this chapter as set forth herein. The Board of Supervisors intends that the requirement of direct preservation of suitable Swainson's Hawk foraging habitat for projects determined to impact 40 acres or more and the option of an impact mitigation fee for projects determined to impact less than 40 acres, in the amount set forth in this chapter, shall be included as one of the mitigation options. Said mitigation shall arise when the environmental review process for a request falling within the scope of this chapter concludes there would be a significant impact or a significant cumulative impact on the Swainson's Hawk foraging habitat for which mitigation, pursuant to all applicable provisions of the Public Resources Code Section 21000 et seq. and the California Code of Regulations, Title 24, Section 15000 et seq., is required. The Board also recognizes its continued authority to determine, based on specific economic, social, legal, technical or other considerations, that mitigation for Swainson's Hawk foraging habitat is infeasible or that evidence has been presented to the Board which the Board determines eliminates the need for such mitigation.
