POCD Takes On Coastal Vulnerability

File PhotoIn the next 10 years, Branford hopes to deal with issues of sustainability and coastal resiliency.

The Steering Committee for the Plan of Conservation and Development (POCD) discussed those issues, and several others, during a meeting Thursday at Fire Headquarters. The state requires municipalities to update their POCDs every 10 years.

Diana Stricker PhotoOther topics Thursday included establishing a coastal vulnerability commission; and increasing freeboard, which is the amount of space above the flood line.

The next meeting will be held March 14 from 4:30 to 6:30 p.m. in the basement conference room at Town Hall. It is anticipated the results of the online surveys will be discussed then. There will also be a telephone survey in March.

The POCD serves as an advisory document, unless the Planning and Zoning (P&Z) Commission ties POCD recommendations to specific zoning regulations.

Promoting Sustainability

One of the goals of the POCD is to promote sustainability and resiliency.

Strategies include evaluating and implementing ways to reduce energy usage; encouraging residents and businesses to reduce energy usage;  promoting water conservation; promoting waste-reduction and recycling; and continuing to educate residents about sustainability.

“This is probably one of the most important things we will be talking about in the next 10 years,” said committee member Catherine Lezon. She said the POCD should strongly promote these goals. “I think we ought to be pro-active,” said Lezon, a member of Branford’s Economic Development Commission.

Diana Stricker PhotoCommittee member and local environmentalist Bill Horne (pictured) said he thinks the POCD should strongly suggest that the town support the state’s goals of reducing greenhouse emissions. He also said the town’s Clean Energy Taskforce should be reactivated.

Resiliency is described in the POCD workbooks as “the community’s ability to withstand, respond to, and readily recover from sudden changes or adversity.” It suggests the town should continue participating in the regional Hazard Mitigation Plan.

Branford is in the process of updating the regional Hazard Mitigation Plan  which the town approved in 2014. The plan identifies potential natural disasters and ways to reduce or mitigate their effects. Once the plan is in place, communities may apply for FEMA grant money for mitigation projects.

Possible strategies to promote sustainability are identified in the POCD workbooks, which are also on the Town’s website.

Glenn Chalder of Planimetrics, the consulting firm hired to oversee the POCD updating process, said sustainability can refer to many issues, and it’s important for the town to “start the dialogue today.”

The POCD draft workbook describes sustainability as “the philosophy of encouraging activities that allow present generations to meet their needs without compromising the ability of future generations to meet their needs.”

New Coastal Vulnerability Commission?

File PhotoThe Steering Committee has been discussing the merits of establishing a commission or board to deal with coastal issues, especially because Branford has one of the longest coastlines in the state.  At one of the first POCD meetings, numerous residents expressed concern about rising seas, severe storms and climate change.

File PhotoThe issue Thursday was whether the POCD should recommend establishing a new commission or perhaps expanding the goals of the town’s Flood and Erosion Control Board. The state requires towns to have Flood and Erosion Control Boards to deal with ways to combat flooding and erosion through physical structures like seawalls, dams and drains.

Committee member Peter Bassermann, who is also the chair of the Inland Wetlands Commission,  said perhaps the POCD should first define the responsibilities of a board or commission that would deal with coastal vulnerability.

Chalder pointed out that the POCD can recommend a new commission, but it would be up to the town to create it.

Freeboard

Freeboard, which was originally a nautical term, is used by FEMA to refer to the amount of free space above the Base Flood Elevation (BFE), which is the height of where floodwaters would reach.  So 1 foot of freeboard would be 1 foot above the BFE.

Chalder said many communities are adding freeboard height because of the increase in severe storms and coastal flooding.

Connecticut currently recommends 1 foot of freeboard for homes in coastal or riverfront areas for new construction, substantial renovation, or when elevating a home.

Horne said he supports adding additional freeboard because of rising seas. However, he said the POCD can recommend the increase, but it would be up to the town to enact it. “This is the first step,” he said.

Chalder said “the issue of freeboard is a sensitive one to people …but it’s probably a good idea for Branford.”

Elevating homes is a complex issue because of the expense and also because of changes to the viewscape for other neighbors.

The town’s Coastal Resiliency Plan, a 50-page report that was adopted in 2016, addresses multiple issues, including the possibility of increasing the amount of freeboard. The plan is on the Engineering Department’s page of the Town’s website.

Diana Stricker PhotoThe Steering Committee also discussed the importance affordable housing issues; and the practicality of creating a design review board to evaluate new commercial projects.

Chalder said the committee will continue discussions over the next few months and hopes to have a draft prepared by June. There will be a public information session to discuss the draft, which will be posted on the Town’s website. A public hearing will be held in the fall to discuss the final version of the POCD.

The Steering Committee members are: Town Planner Harry Smith, Phil Carloni, Bill Horne, Gavin Renz, John Lust, Joe Chadwick, Marci Palluzzi, Terry Elton, Barbara Ricozzi,  Cathy Lezon, Peter Bassermann and Vinnie Hanchuruck.

People building or rebuilding must seriously consider how high above the bass flood elevation (BFE) they want their first floor to be and for how long, taking into account both what has happened in the past and what is predicted to happen in the future.  FEMA determines the BFE from past flood elevations.  Average sea level in Long Island Sound (LIS) rose about 8 inches between1936 and 2016, an average rate of 0.1”/year (CT Institute for Resilience and Coastal Adaptation).  Satellite measurements since 1993 show that global average sea level has risen at an average rate of 0.114” per year and that during that time the rate of increase has risen by almost 3% each year (Nerem et al, Proc. Natl. Acad. Sci., http://www.pnas.org/content/early/2018/02/06/1717312115).  Projecting that annual increase in the rate of sea level rise predicts an increase of global average sea level of more than 2 feet by 2100.

Other factors affect LIS sea level.  We’re all familiar with the effects of tropical storms and nor’easters.  In addition to increasing sea level directly, the melting of the Greenland and Antarctic ice sheets reduces gravitation attraction by the ice, lowering nearby sea level and increasing it farther away.  The Gulf Stream pulls water away from the coast; if the Gulf Stream slows, sea level from New York to Canada can rise by several inches (as it did briefly in 2009-10; Goddard et al, Nature Communications DOI: 10.1038/ncomms7346). 

We know that sea level is going to rise, and we know that burning fossil fuels and increasing the level of greenhouse gases (GHG) in the atmosphere is causing it.  We need to plan for the projected sea level increase in the near future and also take steps to limit future changes to the greatest degree possible by reducing our GHG production to 55% of 2001 levels by 2030 and 20% of 2001 levels by 2050 as called for in the 2018 Connecticut Comprehensive Energy Strategy.
