I am not an attorney and recommend you seek legal confirmation of what follows:
Subparagraph 4-A, ยง3101, allows a road association, "through its commissioner or board", to address "present and future repair of a private road, way or bridge as authorized by the owners...". The phrase, "future repair", is the key here. I believe this permits you, with majority owner approval at a duly called road association meeting, to fund the survey and raise substantial contingency funds for the purposes you state.
