Creating a One Water Solution for a More Sustainable and Resilient New Orleans
Complimenting ongoing water infrastructure investment, New Orleans is working to create water-based community development:
Aligning and streamlining water-related governance, policy, and funding.
Harnessing public space to safely detain stormwater and recharge sinking soils.
Leveraging water investment to spur economic and community growth.
25
Thomas Strategies Waggonner & Ball Architects
Creating a One Water Solution for a More Sustainable and Resilient New Orleans
The Goal: Aligning and streamlining water-related governance, policy, and funding.
The Challenge: Decades of deferred maintenance funding; inconsistent system-wide strategic planning; and multiple governmental entities managing aspects of a single water system.
The Opportunity: Approval of a framework for drainage service fee; enacted governance reform legislation; and first-time comprehensive stormwater management zoning and permitting regulations.
26
Thomas Strategies Waggonner & Ball Architects
Creating a One Water Solution for a More Sustainable and Resilient New Orleans
The Goal: Harnessing public space to safely detain stormwater and recharge sinking soils.
The Challenge: Damage to the City’s aging drainage pipe system in exacerbated by subsiding soils. The estimated cost of a pipe-only solution is simply unaffordable.
The Opportunity: The City is beginning to identify green infrastructure investment opportunities among ongoing post-Katrina street, park space, and blighted property renovation projects.
27
Thomas Strategies Waggonner & Ball Architects
Creating a One Water Solution for a More Sustainable and Resilient New Orleans
The Goal: Leveraging water investment to spur economic and community growth.
The Challenge: Most of the City’s canals and other waterways provide little value as spaces for public life and commercial attraction. Existing surface level water infrastructure is unsightly, dangerous, and walled off.
The Opportunity: The City recently partnered in the development of the Urban Water Plan that identifies short- and long-term pilot projects and economic development strategies to increase community access and private-sector investment surrounding water and green infrastructure.

Harnessing Community Expertise to Define Mission and Build Support
New Orleans Sewer, Water, and Drainage System Citizen Task Force
Greater New Orleans FoundationUrban Water Series
32
To help redefine stormwater management in Greater New Orleans, local business, civic, and neighborhood leaders initiated two major grassroots efforts to contribute expertise and build community support.
Thomas Strategies Waggonner & Ball Architects
New Orleans Sewer, Water, and Drainage System Citizen Task Force
33
Created at the behest of local government, the citizen task force included over forty business and civic leaders and organizations to review and make recommendations on all aspects of water management policy, financing, infrastructure and operations.
Thomas Strategies Waggonner & Ball Architects
Citizen Task Force Recommendations to Improve Stormwater Protection
Governance: Consolidate all stormwater assets and policy under a single authority and enable increased regional and public-private strategic investment planning.
Policy & Operations: Institute a prorated drainage service fee and harness existing blight, housing, zoning, and economic development-related policies to mandate and incentivize green infrastructure investment.
Infrastructure Investment: Capitalize on ongoing post-Katrina public space and street projects to incorporate green infrastructure features.
34
The goal of the task force was to identify stormwater governance, operational, and investment opportunities that leverage existing funds, projects, and policies.
Thomas Strategies Waggonner & Ball Architects
Create a Comprehensive Water Management Regulatory and Investment Framework thatutilizes the City Master Plan, zoning, permitting, blight policy, property rehabilitation assistance,and other land use controls to incentivize and mandate runoff reduction from private property.
I. Implement Land Use Policies that Ease Stress on Drainage Infrastructure

II. Consolidate & Integrate Local Stormwater Management
37
Thomas Strategies Waggonner & Ball Architects
Formalize intergovernmental coordination and inter-parish compacts to achieve regional-level stormwater management planning and infrastructure investment.
Establish a Stormwater Advisory Committee to advise SWBNO and City on long-term stormwater management policy and investment planning.
II. Consolidate & Integrate Local Stormwater Management
38
Thomas Strategies Waggonner & Ball Architects
Establish quantifiable performance and investment goals to guide implementation of integrated stormwater management advancements by SWBNO and the City.
Reduce stress on city drainage system by using federal hazard mitigation funds and other resources to add stormwater storage and other integrated water management safeguards to planned improvements to streets, canals, and public space projects.
III. Build on Existing Initiatives to Invest in Integrated Stormwater Protection Policies and Projects
39
Thomas Strategies Waggonner & Ball Architects
Enhance proposed SELA underground drainage culvert projects, still in design phase, to ensure adequate connectivity to city drainage pipes and include water storage features.
Design Monticello Canal improvements to ensure effective inter-parish drainage capacity.
IV. Modify Planned Improvements to Ensure Greater Effectiveness & Sustainability
40
Thomas Strategies Waggonner & Ball Architects
Leverage Existing Policy to Effect Community-Wide Improvements
41
The task force identified several existing fee structures and public policies that could incentivize community green infrastructure investment. Establish a parcel-based drainage fee that
can be discounted based on onsite conservation measures.
Mandate minimum stormwater control measures for private properties above a prescribed size.
Incentivize enhanced stormwater control measures in awarding public financial assistance for private-sector housing and commercial development.
Establish minimum design standards for incorporating green infrastructure in public projects.

Stormwater Management Funding
Currently funded by dedicated property taxes in each Community and Parish.
Significant amounts of tax-exempt properties owned by charter schools, public and private universities, and churches.
Need for drainage service charge to supplement property taxes.
66
Thomas Strategies Waggonner & Ball Architects
Drainage Service ChargePolicy Considerations
Which organizations and missions should the new drainage service charge cover?
Should drainage service charge collections be shared across political jurisdictional boundaries?
Should the drainage service charge be based solely on impervious surface area or a combination of total area and impervious surface area?
Should the cost allocation be differentiated upon which geographic areas are being drained?
67
Thomas Strategies Waggonner & Ball Architects
Drainage Service ChargePolicy Considerations
Should service to water system customers be turned off for non-payment of drainage charges?
What consequence should non-water customers face for non-payment of drainage charges?
Should revenue requirements, existing millage revenues, and impervious surface areas be allocated at the system level, at the customer class level, or at the individual customer level?
What properties should be exempt from drainage service charges?
68
Thomas Strategies Waggonner & Ball Architects
Drainage Service ChargePolicy Considerations
What is the basis for credits?
What level of public participation is necessary and appropriate in development of the new Drainage Service Charge?
What level of service will be provided from this Drainage Service Charge?

Progress at the Nexus of Water and Power
Retrofit of power generation system through a $141 million Hazard Mitigation Grant.
Building smarter, with greater reliability, resiliency, and sustainability.
71
“Recovery is about better handling the storms we face in the future, and about being a better place to live before, during, and after those storms. So, a recovery without resilience is not a real recovery, and resilience without sustainability is not resilience.
So it’s critical to our recovery that we invest in not only rebuilding back what we had before, but also investing in making sure that that rebuilding is safer, stronger, and smarter than we had before, with a better understanding of our relationship to the environment in which we live.
Sometimes “Safer, stronger, smarter” means a tweak to an existing idea; but at other times a tweak isn’t enough and we’re required to reimagine our very relationship with our environment and how we adapt to it.”
