9.04. Amenities Plan and River Zones.—Complementary to the
comprehensive water resources plan provided for by Section 3.02,
the Commission shall develop and adopt, and from time to time re-
view and revise an amenities plan and programs for the development
and preservation of the aesthetic, scenic and historic values along
the Potomac and its tributaries, and may adopt such plan or any
revision thereof in such part or parts as it may deem appropriate.

In developing, reviewing and revising the amenities plan, or parts
thereof, the Commission shall give consideration to agricultural, in-
dustrial, commercial and residential values.

In developing, reviewing and revising the amenities plan, or parts
thereof, the Commission shall give consideration to relevant por-
tions of federal, state, regional and local plans, whether prepared
by signatories or their agencies, by local or regional planning com-
missions, by local governmental units or organizations thereof, by
soil and water conservation districts, by regional resource use asso-
ciations, or by other governmental agencies or organizations. Such
consideration shall be required only with respect to such plans as
are presented to the Commission in the manner the Commission may
provide.

The plan shall include public and private areas, waters, land, land
uses, structures, projects and facilities which are necessary, in the
judgement of the Commission for the balanced development, conser-
vation, utilization and preservation of such values. Any such plan
shall also provide for:

(a)  river zones and their accessibility;

(b)  instituting land use plans and controls within river zones;

(c)  acquiring or otherwise preserving existing and potential parks
and parkways, scenic areas, open spaces, recreation areas, historic
areas, trail corridors, wetlands or natural areas within river zones.

A river zone, as used in this article, means such portion of the
Potomac River or a tributary, including the islands, and an area
along the shores, of such length and extending inland such distance,
as the Commission may determine, but no river zone may extend
inland more than one mile except with the concurrence of the govern-
ing body of the locality in which such zone is located.
