Alternatives for Improved Stormwater Management

5.1 GENERAL ISSUES

The primary focus of this project has been to determine if an alternative stormwater management
organization is needed and, if so, what kind of an organization would best fit the needs of the
Grand Valley while being as consistent as possible with the Steering Committee priorities
(discussed above in Section 4a). The Steering Corrunittee process resulted in two primary
conclusions:

· A unified valley-wide organization is needed to engage in activities that lend themselves to a
multi-jurisdictional approach, and

. The existing entities should also continue providing local services within their jurisdictions.

This section discusses the kind of activities that a valley-wide solution should address, activities
that are best left with the local jurisdictions, and discusses the alternative organizations that
would meet the needs of the project.

5.1.1 What Activities Would a Valley-Wide Solution Address?

The activities needed for a valley-wide effort are those activities that include a regional scope
and perspective. These activities range from planning and regulatory compliance to construction
and maintenance of large capital improvements that handle major drainage flows from multiple
jurisdictions. A limited amount of regional administration, including stormwater quality permit
coordination, would also be advantageous.

Following is an outline of the major multi-jurisdictional activities that are proposed for inclusion
in a valley-wide organization:

. PlanninglRegulatory

a) Floodplain mapping and management
b) Drainage Basin Planning Studies
c) Creation of a unified drainage criteria manual
d) Stormwater quality National Pollution Discharge Elimination System permit
requirements

. Construction of Large Multi-jurisdictional Projects

. Operations and Maintenance of Large Multi-jurisdictional Projects

. Administration

a) Billing
b) Customer service - 1 phone call
c) Coordinated representation to StatelFed agencies

5.1.2 What activities would local communities give up or keep?

As discussed in Section 2, most of the services that the individual entities provide within their
jurisdictions are of a non-regional nature. The Steering Committee agreed that the local
jurisdictions were the logical and most efficient providers of these services and concluded that
these services should remain with the local jurisdictions. Local services inclUde routine items
