The City's plan is to complete the system as quickly as possible in order to keep inflation costs as minimal as possible. The Iowa Flood Mitigation Board Award presumes the system will be completed in 20 years – 2034. The system could be completed in 13 years – 2030, based upon the time needed for design, property acquisition, coordination with other entities (railroad), and construction.
Considerations when developing the timeline:
- Hydraulic impacts on other areas
- Enhanced interim protection ability
- Protection of critical infrastructure
- Property currently owned by City
- Encourages complementary development
- Emergency access
