2. Design Team makeup and philosophy
Large scale production focused on Design Engineers and the General Contractors
The Design Team is made up of:
County Representative
Local Design Engineers
General Contractors
Local BMP Expert
Maintenance Contractor
Third-Party Completion certifier
Design Team’s role:
Help select projects
Peer review
Negotiate with suppliers
Asset life-cycle considerations integrated into Program.
Put West Coast Info into this
Make general

3. Project selection processes
Community based approach to the watershed:
Advocacy Groups
Municipalities
Local engineer
BMP approach
Select BMP and look for opportunity (ponds, stream restoration, etc.)
Complex overlay approach
Put West Coast Info into this
Make general

4. Overlay approach to Project Selection
Through GIS desktop analysis, the design engineer takes broad brush steps to locate potential areas to focus planning efforts
The GIS desktop analysis considers:
Land ownership
Geographic bundling
Geographic focus
BMP application sites
Permit time
Exclude sites with bad soil, flood plain, etc.

5. Potential project areas identified for field verification
The GIS desktop analysis creates maps with each potential project area identified
Based on field verification, specific project locations are identified, conditions confirmed.

6. Projects are prioritized on cost basis
The Design Engineer, with the help of the General Contractor, provides high and low conceptual cost estimates for each of the devices that were determined to be the best fit BMPs for each Task Order
The devices are then prioritized based on cost and long term maintenance considerations

7. Innovation: Project Delivery System
The Clean Water Partnership brings innovation through more flexible delivery system:
Connecting General Contractor and Maintenance Contractor to the Design process
Flexible contract structure with engineers and contractors and incentivizing each differently
Dispensation from onerous permit process
Goal: Design/Build vs. Design-bid-build
Paradigm shift

8. GC and Maintenance Contractor involvement
Bring Value Engineering, feasibility and constructability to the design process early.
Negotiations:
Proprietary systems must address GC and maintenance contractor concerns.
Project bundling
Project sizing
Supply stream for planting, media, etc.
Cost per acre approach

9. Flexible contract structure with Primes and subcontractors
Design Engineers no longer selling labor or work on a cost per hour basis.
DE contracts based on % of construction costs
DE connected to GC through contract scope
GC services paid with base fee and incentive fee
GC competes work on unit price basis
CWP can buy in bulk, prior to project and based on planning requirements

10. Innovation breeds innovation
Dispensation from onerous permitting process saving time and engineering costs
Alternative Compliance Program: the CWP is able to manage this program more effectively
Working with Advocacy Groups
Working with municipalities within the County
MS4 long-term permit planning
Extension of DoE department as flexible resource

11. Summary
Project selection integrates the community and the lifecycle of the facility.
The paradigm shift has occurred with the County and now the shift needs to occur with the design engineer and contractors.
Project delivery structure is attracting the innovation
