Storm Water Management
Based on direction from the MIALG, a group composed of primarily City staff but also
including developers and consulting engineers spent 9 afternoons from May to
October attending trainings about stormwater management.
Three Key Lessons from this series:
1.Managing stormwater is a key regional priority.
Water doesn’t respect jurisdictions.
We need to work together across the metro.
2.We are facing more frequent, more intense storms that result in increased
flooding and significant erosion.
3.Additional tools and design methods are available to address ongoing and
increasing stormwater issues for existing and new developments.
Why are we here?
•In the period 2004-2024, local governments will have spent nearly $415
million on stormwater projects and operations.
- $14,325,855 for commercial
- $209,933,913 for residential
- $1,074,441 for industrial
•Amount of yearly public expenditure is increasing in the region.
•Waukee expenditure from 2014-2017 is $91,376
What are local governments contributing?
Stormwater Damage
•Previous design methods are no longer sufficient. New development
under these methods will exacerbate known problems.
•Effective stormwater management is an entire suite of guidelines and
solutions that can be utilized with new development, redevelopment,
existing built areas, and agricultural areas.
•Moving forward, using the latest methodologies and best practices will
help address known problems and provide a more consistent and
effective approach to stormwater management. Proactive design is
cheaper and less disruptive long-term.
“Gray Infrastructure” (flumes, pipes, structures)
PLUS “Green Infrastructure” (natural infiltration, detention)
An Enhanced Approach
We’re All In This Together
•Empower staff to work with other city staffs across the metro to determine
enhanced stormwater management approaches for recommendation to
Council.
•Create a “toolbox” of techniques
•Use green infrastructure where appropriate
•Consider life cycle costs of stormwater management
