Summary

Drafter Mike Cowdrey presented a 3-bay, 60-foot-deep salt-shed plan; after volume calculations the committee favored revising to four bays with a 40-foot depth (14', 20', 20', 20' allocations), reinforced concrete walls, buttresses and paved bays to meet storage needs of about 350 cubic yards of sand and 30 tons of salt.

The committee reviewed a proposed salt-shed layout and directed the drafter to revise bay widths and depth after discussing storage volume, roof support and maintenance concerns.

Mike Cowdrey presented a three-bay plan with 12-foot bays and 60-foot depth, vertical siding and 4 feet of concrete above grade. Committee members questioned whether three 12-foot bays would meet the town’s needs.

William MacDuffie Sr. and William MacDuffie Jr. argued for larger bays. MacDuffie Sr. estimated the town typically stores about 350 yards of sand and about 30 tons of salt at a time, and said sand storage bays should not have a wall between them to make loading easier. After running the numbers, the committee favored a revised layout with a 40-foot depth and bay widths reallocated to support different materials: roughly 14 feet for salt, 20 feet for mix and two 20-foot bays for sand. MacDuffie Jr. noted shortening depth and adding a fourth bay could increase overall storage capacity while reducing pour complexities.

Structural and finish considerations included adding buttresses and an 8-foot to 10-foot rear concrete wall to resist piling loads; Cowdrey suggested consulting a truss engineer for roof pitch and a concrete specialist for buttress/footing design. The board agreed all bays should be paved and discussed lighting options (yard light vs. strip lighting) for safe access and operations.

Next steps: Cowdrey will update the salt-shed plan to reflect the committee’s preferred bay widths and 40-foot depth and will verify roof and wall details with a truss engineer and concrete contractor before the next meeting.
