• The Blue Cities approach
• Implementing the approach
• Project case studies
• Successes and Challenges
Strategies for Urban Development: The Blue Cities Approach and Case Studies
• Environmental Science and Advocacy Organization founded in 1965
• Mission: To use science, advocacy and the law to protect, preserve and enhance the Charles River and its watershed
Charles River Watershed Association
• Water quality • Sediments • Floods and low flows • Groundwater • Ecosystem and habitat • Algal blooms
Impacts of Urbanization on Rivers
Standard Urban Development
• Pave • Pipe • Pump
Standard Urban Problems
• Floods
• Water table changes
• Degraded rivers and streams
• Hot, noisy urban canyons
In Massachusetts, average annual runoff increases from 4.2” to 23” and groundwater recharge decreases from 21” to 6.3”.
Impacts of Urbanization on Natural Water Cycle
Blue Cities is a water-oriented approach to urban development and redevelopment that promote designs for the built environment that engages with every stage of the water cycle. Going beyond “green” building, “blue cities” embraces green infrastructure design with the aim of restoring the natural water cycle in the built environment
CRWA’s Blue Cities Initiative
• Water centric planning and urban design
• Mimic natural water cycle and restore hydrologic integrity
• Retrofit sites to incorporate “green infrastructure”
• Build on links to open space, public health and public realm needs

Blue Cities Guide
Public realm/neighborhood scale approaches
• Green streets and Greenways • Integrate stormwater management
with existing open space • Stream daylighting • Regional retention and detention
systems
Large site scale approaches
• Parking lot retrofits • Courtyard retrofits • Permeable
pavement • Constructed
wetlands and other retention and detention systems
• Cisterns/ rainbarrels • Rain gardens • Stormwater planters
Residential/ small site scale approaches
Blue Cities Analysis and Design Process
Existing Conditions Analysis and Data Compilation
Neighborhood Assessment and Surveys
Issues and Opportunities Analysis
Concept Design and Visualization
Recommendations for Green Infrastructure Retrofits
Implementing Blue Cities • Creating Partnerships
– Engaging cities, towns, state, universities / institutions
– Grassroots advocacy and work with community groups
• Public Education, Site Visits, Workshops
– Public charettes and forums – Target audience workshops – Site visit to University of New Hampshire
Stormwater Center
• Developing Sub-watershed Restoration Plans – Green infrastructure assessment and
design in urban and sub-urban contexts
• Building Demonstration Projects – Green Street retrofits – Site scale retrofits
Blue Cities Projects • Environmentally Sensitive Urban Development
– Blue Cities Guide- North Allston, Zakim North and LMA
– Mystic River Collaborative Project – Blue Cities National
• Sub-watershed / Neighborhood Scale – Franklin and Bellingham Subwatershed
Restoration Plans – Subwatershed Plan for Broadway, Chelsea – Green Streets Guide for Allston Brighton,
Boston • Site Scale Demonstration Projects
– Peabody Square Greening, Dorchester – Everett Street Pilot Project, Allston – Waltham Watch Factory, Waltham – Parmenter School and Fletcher Field, Franklin – Chester Avenue and Crescent Ave, Chelsea – Porous Alley Retrofit, Boston

Successes and Challenges
Challenges • Coordination between traditionally silo’ d agencies • Construction supervision and oversight • Post construction monitoring and maintenance • Scaling up beyond demonstration projects • Funding for planning, design, implementation, monitoring,
public outreach and education
• Reduced flooding and increased recharge • Reduced ‘heat island’ effect in urban areas with increased
vegetation • Aesthetic, pedestrian and public realm improvements • Improved water quality in receiving waters • Public support for neighborhood greening
