As a truncated summer season looms, more than a dozen Martha’s Vineyard business owners and trade association representatives have issued an open letter calling for a public summit meeting with the all-Island selectmen and all-Island boards of health to develop unified pandemic policies.

“We can no longer react solely as individual businesses or even towns, but instead must respond as one Island,” wrote the newly-formed All Island Business Task Force, which includes business association members in Edgartown, Oak Bluffs and Tisbury, the chamber of commerce and individual businesses.

The group is asking officials in all six towns to adopt state regulations with no additions, to develop a universal strategy for reopening beaches, parks and other public places, to agree on how mask use will be enforced and to use Islandwide signage informing the public of safety rules.

The letter is signed by Elaine Barse of the Green Room, JB Blau of the MV Year-Round Restaurant Group, Diane Carr of the Hob Knob Inn, Todd Christy of Chilmark Coffee Company, Collins Heavener of the West Tisbury Farmers’ Market, Lora Ksieniewicz of Yoga on the Vine, Aela Mass, of the Martha’s Vineyard Chamber of Commerce, Sarah Omer of Red Cat Kitchen, Erin Ready of the Edgartown Board of Trade, Julia Tarka of Rosewater MV and Rosebud Kids, Greer and Christian Thornton of Atria, Julianne Vanderhoop of Orange Peel Bakery, Melaney West of Stagecoach Taxi and Sarah York of CB Stark Jeweler.
