§ 299-u. Joint construction and operation of projects. Where two or
more adjoining counties have established agencies and have created
watershed districts for the purposes of this act in the watershed common
to the counties, the agencies and the administrative heads or bodies,
subject to the approval of their respective boards of supervisors, may
enter into agreements for the planning, installation, construction,
operation, maintenance, assessments of costs and repair of a joint small
watershed project. Any agency or agencies within this state, established
by a county or counties for the purposes of this act with respect to
small watersheds, may, subject to the approval of the board or boards of
supervisors of the county or counties, enter into agreements respecting
joint projects with one or more "local organizations" in other states as
defined in section ten hundred two of title sixteen of the United States
code. The provisions of all sections of this article concerning the
planning, installation, construction, operation, maintenance,
assessments of costs and repair of, and the approvals required for a
project within a single county of this state, shall apply with equal and
full force and effect to a joint project, but nothing herein shall be
deemed to prevent or restrict the additional applicability thereto of
any requirements of another state in any matter relating to its interest
or the interests of its subdivisions therein.
