Hot dip galvanized;

Stone embankment

We don't have 4x4's in our material types.

Were you envisioning a cedar 4x4 here?

We need to have a meeting w/ SSNERR management to discuss this area

Is this a 2x10 joist?

Probably need a post detail or some indication that it is (2) 2x4's screwed together and what hardware we want

Need bumper board, typ

We need to confirm surface material. I think we want compacted soil (use existing) but may need to put wood chips on it or something until it compacts back to a trail

Anything with a fuel tank (welder?) must be in containment Please note that construction over the water may only occur from July 1- September 15 No heavy equipment in the water at any time.

should this be called a joist for consistency with the drawings?
