Motivation for Collaboration Broward’s Climate Action Plan Working Toward Resilient Coastal Communites - Broward County Natural Resources Planning and Management Motivation for Collaboration Broward’s Climate Action Plan GOAL PC-1 : Create collaborative intergovernmental practices…and assist in adaptation to the regional consequences of climate change… Action PC1.6: Collaborate broadly on mitigation and adaptation policies. (…implementation of a suite of planning tools and climate change mitigation and adaptation strategies…) Action PC-1.6 Collaborate broadly on mitigation and adaptation policies Broward County should collaborate with municipalities, the Broward League of Cities, neighboring counties and other regional public and private entities to assist in the coordination, development, and implementation of a suite of planning tools and climate change mitigation and adaptation strategies. This should include establishing action targets and reaching agreement on one or more standardized methodologies for emissions measurement and reporting. DEP Agreement No. CM238 DEP 55-236 (08/11)

One Foot Sea Level Rise Scenario Working Toward Resilient Coastal Communites - Broward County Natural Resources Planning and Management One Foot Sea Level Rise Scenario Major Impacts 2040 – 2070 No areas below 1ft. SLR in Lazy Lake. In General (County Wide) Parks and historical sites Select local roads Natural areas Low-lying tidal areas Municipal scale inundation maps provide at-a-glance overviews of areas within the City that are low lying and likely to be vulnerable to flooding associated with sea level rise DEP Agreement No. CM238 DEP 55-236 (08/11)

Two Foot Sea Level Rise Scenario Major Impacts 2060 – 2115 No areas below 2ft. SLR in Lazy Lake. In General (County Wide) Local streets Low lying communities Low lying areas in golf courses and parks Marine facilities

Priority Planning Areas No Priority Planning Areas in Lazy Lake. Identifies areas located near tidal water bodies at increased risk of inundation under a two foot sea level rise scenario, projected to occur as soon as 2060.

Working Toward Resilient Coastal Communites - Broward County Natural Resources Planning and Management What happens if a Land Use map amendment is in a Priority Planning Area for Sea Level Rise? The Planning Council shall consider the following: Sea level rise/flood protection mitigation strategies within local comprehensive plans and/or development regulations Flood protection improvements committed to by amendment applicants, which would mitigate or enhance flood protection and adaptation from rising sea levels Recognizing our common vulnerabilities and the need for action, the four Counties came together and signed an agreement to work together to address policies at the state and federal level. They agreed to develop technical tools to lay a foundation for regional mitigation and adaptation strategies. And they wanted to hold regular summits to discuss projects and emerging concerns.

City Maintained Arterial Roads Vulnerability Assessment Only City-Owned Arterial Road Segments are shown. One vulnerable Arterial Road Segment is identified during a two foot SLR. The Segment is not vulnerable during a one foot SLR.

City Hall Vulnerability Assessment Possible roadway access issues within a 1000-foot radius. NE 19th St NE 4th Ave Both may be vulnerable during 1 & 2ft. scenarios.

City Parks Vulnerability Assessment 3 vulnerable city- owned parks Colohatchee Park up to ~60% vulnerable

Middle River Subdivision Working Toward Resilient Coastal Communites - Broward County Natural Resources Planning and Management Special Interest Middle River Subdivision Low lying neighborhood with many vulnerable streets Coral Gardens Dr NE 14th Ave NE 16th Ave NE 16th Ter NE 17th Ave NE 17th Ter NE 18th Ave NE 26th Dr NE 27th St NE 28th Dr NE 28th St The Middle River Subdivision of the City of Wilton Manors has a large number of streets located at or below projected sea levels during a two foot scenario. No land within the Middle River Subdivision appears to be affected during a one foot scenario DEP Agreement No. CM238 DEP 55-236 (08/11)

Call to Action Sign on to the Mayor's Pledge - RCAP Consider which strategies presented in CCAP and RCAP you should implement Update your Comprehensive Plan to include resilience policies Pay careful attention to Land Use amendments in vulnerable locations

Call to Action (cont) Use the technical tools to increase awareness among your staff/Board of vulnerable infrastructure Ensure that climate issues are part of the Capital Improvement Planning process Look into using AAA as a tool for prioritizing strategic adaptation investments

Conclusions Broward County NRPMD hopes you find these policy and technical tools useful. We can provide the GIS layers upon request. We continue to work on technical and policies tools to support community resilience. We are available to make a similar presentation to your Board of Commissioners.
