Key questions to consider during the planning phase for green stormwater infrastructure.
Link to this table
|Ownership||Should the GSI practices be owned by the community government, by individual property owners, or by another entity (such as a conservancy or port authority)?|
|Maintenance||What are the recommended maintenance frequencies and practices? How often is the community willing to maintain their GSI practices?
Should there be shared responsibility for maintenance?
|Performance||How much stormwater needs to be treated?
What contaminants should be targeted?
|Cost||What is the available budget range?
Are higher cost options acceptable if they provide additional community services?
|Funding||What are the available funding sources: tax revenue, grants, donors, developers?|
|Technical resources||How will in-house and consultant resources be coordinated?|
|Community support||Are there individuals or groups willing to provide volunteer maintenance?|
|Community outreach||Is the outreach goal to inform people of the project, or is the goal to solicit public input?
Who is best positioned to effectively lead community outreach efforts?
|Exploration||Is the community interested in newer techniques that may require more interventions or would they prefer to stick with the “tried and true” techniques?|
|Ammenities||Should the GSI practices serve as community amenities beyond stormwater management?
What ancillary benefits should the GSI practices provide?
|Ordinances||Is the community interested in using ordinances as a vehicle for implementing GSI?
Are GSI ordinances an option for the community?
|Permitting||Which permits and regulatory approvals are needed?|
|potential roadblocks||Who may benefit from the GSI project?
Who may be adversely impacted by the GSI project?
|Climate change and resilience||To what extent are we willing to adaptively manage the GSI product in the future to accommodate climate change?
Are options designed into the product for future implementation?
|Canopy cover preservation||Is there existing canopy cover in place that would be removed by the GSI?
Can the existing canopy cover be preserved to retain the site’s pre-existing, natural pollutant removal, rainfall interception, evapotranspiration, and shading capabilities?
