Group 1

All municipalities and state agencies adopt a cohesive policy, for the Metro Boston area, to expand tree canopy by 20% annually, by 2024. The policy will include a replacement plan for existing trees.  

Group 2

Implement a regional infrastructure coordinating committee: 

  • Proposed as part of Climate Ready Boston – convening of infrastructure providers 

  • Suggest expanding to regional scale 

  • Infrastructure not limited to city boundaries 

  • Benefits of infrastructure / GI not limited to city boundaries 

  • Timeframe: established 2021 

  • Unit: new legislation for dedicated funding source (capital + O&M funds); participation and leadership buy-in 

  • Salient Outcome: Shared plans and budgets; measured/shared monitoring strategies 

Group 3

Dedicate 1% of capital and operating budgets to GI development and maintenance 

  • Timeframe: 2023 – regional action plan developed 

  • Units: $$ invested, # of projects, equity of distribution (higher $$ in environmental justice communities) 

Group 4

  • Green roofs: % of new development must include green roofs 

  • Beach closures: reduce beach closures by XX% through building GI in the beach’s watershed area 

  • Rain barrels: increase participation in local rain barrel program by XX%; implement rain barrel program in all metro Boston communities 

  • Urban forest: establish a regional canopy cover goal and determine guidelines for species selection 

  • Regional GI incentives/policies: establish regional GI incentives; XX% of GI projects must be in environmental justice communities/neighborhoods 

  • Impervious surface: reduce impervious surface coverage by XX% 

Group 5

  • 5% impervious cover reduction (fixed/tied to baseline) 

  • Considerations: how to measure, New Hampshire TMDL example 

  • 1 million added trees for Metro Mayor region 

  • Peak runoff / future-oriented targets 

  • E.g. 25:2 model; 25 year / 2 year, mitigate difference 

  • 10% adoption (retrofit?) of “green street” infrastructure projects and “green school lots” 



Regulatory Tools 

  • Getting municipalities to pass standardized off-site mitigation measures (short term) 

  • Regional agreement around tree replacement and planting (short term) 


  • Evaluate capital improvement plans for GI opportunities (short term) 

  • Consider non-traditional partnerships, e.g. private foundations + utilities (long term) 

  • Statewide regulation mandating green infrastructure funding (long term) 

Operations + Maintenance 

  • More workshops for DPW folks who are responsible for stormwater/GI design and O&M (short-term) 

  • O&M standards manual for each type of GI (medium term) 

  • Regional messaging / interpretive signage clearing house (short-term) 

Making the Case for GI / Other 

  • Create a certification program or continuing education credits for municipal staff (short-term) 

  • Create a regional database with local case studies and possible relevant GIS layers (short-term) 

  • Database of GI projects + status for learning, sustainability, and long-term data on impacts (long-term) 

  • GI database + tracking system (long-term)
