SECTIONS IX

Final Two Organizational Alternatives

With the elimination of alternatives C3, C4, and CS, an expanded evaluation of alternatives Cl
and C2 is presented to determine which is the best alternative to meet the needs of the project.
Both alternatives include Alternative A, Status Quo, for activities that are within the boundaries
of each jurisdiction and not multi-jurisdictional in nature. As outlined above, the primary
activities of the multi-jurisdictional organization are:

. PlanninglRegulatory,

. Construction of Large Multi-jurisdictional Projects,

. Operations and Maintenance of Large Multi-jurisdictional Projects, and

. Administration.

Following is a discussion of examples of how specific activities would be performed by the new
organization under Alternatives Cl and C2. Either C1 or C2 could perform the activities.

6.1 MAJOR ACTIVITIES

Floodplain Mapping and Management

The primary concept for each of the two alternatives is the completion of multi-jurisdictional
activities for and in each of the jurisdictions. For example, the floodplain mapping and
management activity would be completed on washes that extend through a number of
;'C~ jurisdictions and on major washes that

for the benefit of all jurisdictions and
for all residents of the valley that
benefit from the mapping and
regulation of floodplains. It would be
an efficient way to complete mapping
and management, and all participating
jurisdictions would receive the same
mapping studies and be advised in a
consistent manner on the management
aspects, including where and how
development should be controlled in
the floodplain areas.

Drainage Basin Planning Studies

The completion of drainage basin planning studies would work in a similar manner. The studies
would be focused on multi-jurisdictional drainage and flood control issues including major
drainages that pass through a number of jurisdictions and drainages that are large enough to
warrant regional attention. The selected organization would fund, manage and complete the
