Development, Green

Infrastructure, Tree

Canopy

1) New development/redevelopment designed to adapt to climate

impacts (heat, precipitation, etc.)

Development 2) Redevelopment located outside of the highest hazard areas

Natural

Resources

Protection 3) Natural functions of ecosystems, shorelines and critical habitat

areas will be restored

Management 4) Conserve and manage habitats to support healthy fish, wildlife

and plant populations and ecosystem functions

Restoration 5) Restore ecosystem processes to increase capacity to adapt

Coastal Zone Protection, Storm

Assessment

6) Coastal areas resilient to climate change impacts

Green Infrastructure

Conventional (Gray) Infrastructure Green Infrastructure

Singe function – carry waste and water; built for cars only; electricity from fossil fuels

Multi-functional - store and treat stormwater; aesthetically pleasing; provide wildlife habitat; electricity from wind, solar; multi-modality, etc.

Manufactured materials Manufactured and natural materials

Transports stormwater away from site Manages stormwater on site

Concentrates stormwater and pollutants Naturally treats and disperses stormwater and pollutants

Roads built for cars only Roads that accommodate bicycles and pedestrians, and often, have natural elements too.

Electricity from fossil fuels Electricity from multiple renewable energy sources

Cookie-cutter approach, no room for creativity or complementariness

Work well in tandem with and are complimentary to other types of infrastructure

MAPC’s Code Checklist: http://www.mapc.org/sites/default/files/LID_Local

_Codes_Checklist.pdf

Relax Parking Requirements

Utilize Right-of-Way & Reduce Setbacks

Permit use of Open Drainage Systems

Credits for On-site Retention, Infiltration, Evapo-transpiration

Zoning/Site Plan Review Incentives: • Fee Discount • Development Incentives • Rebates & Installation

Financing • Awards & Recognition

Programs

Proactive MA Communitis

• Chatham – zoning bylaw prohibits new residential units in mapped floodplains - designates ‘conservancy districts’ for land in 100-year floodplain; designates uses as permitted, needing special permit or are altogether prohibited

• Cape Cod Commission – model floodplain district bylaw prohibiting new development in V, no public infrastructure in V and A zones

• Boston – updating their hazard mitigation plan, looking into updating wetlands ordinance - all accommodating for CC

• Cambridge – vulnerability assessment

• Reducing Storm Risk in Developed Areas w FEMA $: Quincy & Scituate help property owners elevate homes/utilities; covers 75% of cost
