6/19/2018 Agencies Already Taking Goals for This Morning Action  To familiarize attendees with how projected Climate-smart agriculture increases in temperature will impact health and infrastructure, and how the built Responding to vegetative fires environment contributes to heat risk.  To explore cooling strategies for the built Mosquito-borne disease tracking environment to mitigate the impacts of increased heat in Alameda County’s Salt ponds as buffer to flooding unincorporated areas. Emergency preparedness training  To inform planning policies . Goals for this Morning Agenda 9:00am-1:00pm Refreshments Provided  Strategies developed will inform, as appropriate:  Heat, Climate, and the Built Environment ▫ The Community Climate Action Plan, ▫ Relevant sections of Specific Plans, Presentations ▫ Amendments to General Plan as mandated  Case Study: Sacramento County by SB 1000, ▫ Residential Design Standards and  Breakout Group Activity Guidelines, and ▫ Discretionary guidance in the permitting  Report Out & Next Steps process. 2

6/19/2018 Example: How Does Heat What Factors Contribute? Affect Health? Children (≤ 5) are  Unemployment  Households without AC especially vulnerable to heat:  Adjust less quickly to  People living in poverty  Households with limited heat English  Households without a  More susceptible to vehicle  No Tree Canopy changes in air pollutants (hot environments favor formation)  Ozone  Impervious Surfaces  Less likely to seek help What Factors Contribute? • Unemployment • Households without AC • People living in • Households with poverty limited English • Households without • No Tree Canopy a vehicle • Impervious Surfaces • Ozone 5

6/19/2018 Here, There, Everywhere  The need to cool is not new Cooling our Community  Strategies already exist Integrated Strategies for Success  Motivations have changed Office of Planning and Environmental Review  Take stock of what you have February 7, 2018  Integrate your strategies John T. Lundgren, lundgrenj@saccounty.net 42 February 7, 2018 Office of Planning and Environmental Review Sacramento County’s Strategies Core Strategy: Shade  Ordinance - Native Oaks  Enhance existing requirements  General Plan – Tree Canopy  More than just parking lots  Zoning Code - Dev. Stds.  Identify co-benefits  LHMP  Utilize Multiple Approaches  Landscape Architect • Discretionary: CEQA Mitigation (e.g. canopy replacement)  SB 1000 / EJ Element • Ministerial: Dev. Stds.  Climate Action Plan (e.g. Zoning Code 50% @15 Yrs.)  • Smart Growth Streets Voluntary/Partnerships  (e.g. Sac Tree, Utilities) Complete Streets  Design Guidelines Office of Planning and Environmental Review Office of Planning and Environmental Review 43 February 7, 2018 44 February 7, 2018 11

6/19/2018 Q & A Visioning the Future Thinking 50 years in the future… with no limitations or constraints… If cooling strategies were implemented, what is one change you might see in the built environment? 49 February 7, 2018 Office of Planning and Environmental Review Breakout Groups ❶ Building ❸ Vegetation & Materials Landscaping Roofing, etc. Break ❷ Pavement & ❹ Transformative Hard Surfaces Built Environments Thinking big, incorporating co- benefits 13

6/19/2018 Breakout Groups Breakout Groups Instructions Tips • Choose a group • Work with new faces • Don’t be concerned about committing • Brainstorm as many ideas as you can • Build on what we’ve resources heard, but add your • Select one “straightforward” idea and one new thinking • Don’t limit yourself to “creative” idea to flesh out your role or expertise • Answer questions on the worksheet • Think outside the box! • Select a “reporter” • Write up 2 ideas on flipchart Breakout Groups ❶ Building ❸ Vegetation & Materials Landscaping Roofing, etc. Break ❷ Pavement & ❹ Transformative Hard Surfaces Built Environments Thinking big, incorporating co- benefits 14
