Sorry I can't directly answer your questions but our road association went through a very similar dilemma I'd like to share in case our experience helps you at all.
Our road association operates under three different ruling bodies: 1) all but two properties are bound by Road Maintenance agreements set up by the developer 2) statutory road association established to "pull in" the additional two properties 3) incorporated under 13-b. But basically, our documents and by-laws defer to the laws of the statutory road association. Per the advise of our lawyer we determined that act of paving our road as governed by our 13-b status could legally be done. However, funding it is what becomes difficult.
Our situation deemed the following facts: Under 13-b we would not be limited to the 1%. However, all contributions must be considered voluntary. We would have little to no legal standing to try and collect payments from non payers and could not file notice of claims against them. Any person (member or stranger) could contribution as little or as much as they wanted to the project, meaning we could fund raise if so desired (bake sale anyone? haha).
While most of our members were in favor and willing to pay their portion, their majority would be meaningless as an effort to collect against those opposed since there is basically nothing we could do to collect under 13-b. The problem with 13-b (the way ours is set up) is the only grounds for collection is small claims court, and since our by-laws defer to the statute regarding maintenance (that says you can't pave) our argument would not hold up in court.
We probably have about 90% on board. Some of our "deep pocket members" are evening willing to pay for those who can't. Problem is, some of the ones on board are only "yeses" if no one is opposed, meaning they want everyone to pay their own portion and not have some members pay the extra, or worse have the extra divided out among the payers. We decided not to proceed unless we had 100% support for these reasons, as well as not wanting stir up relations and have to fight against non-payers as we are fortunate to be a pretty close, happy, community and always vote unanimously on other issues. We chose not to ruin that by paving.
Furthermore, we have huge concerns regarding future maintenance. What we don't know, is under the terms of the statutory road association can we assess fees to maintain that pavement? We believe we can't, which will really mess us up and create a slew of problems later on. Our intent to pave is with the goal of getting the town to accept our road as public so future maintenance wouldn't be an issue, however if the town's people vote against now we're stuck with a paved road we can't maintain.
Now, in our case each member owns their portion of the road up to the center line. This fact motivated a group of members who happen to live in the middle of the length of the road all in favor of paving to pursue paving their sections on their own without the road association's involvement. This raised many more questions and concerns about how to maintain the gravel around the pavement and who maintains the pavement? Ultimately, this idea was also dropped.
We also explored the financing option with little success. For starters, half our members didn't want to be involved in such a group loan, and others wanted to get their own personal load to pay their portion. Leaving less members involved in a group loan that would ultimately mean some members pay more (interest on loan) than others. While we found willing lenders, we believed there could become serious implications in the event properties sold. We would have no legal grounds to continue to collect payments from new owners the way the banks wanted to set up the loans. The burden of the debit would be solely placed on the officers personally, of which no one wants responsibility for. I am very interested in knowing how the lenders you looked at proposed underwriting your loan? Ideally, we would want the bank to use a part of every member's home as collateral so in a sale the debit would be transferred, but this requires every member and their current mortgage holder's signature, and is far too complicated for the bank to willingly do.
The compromise we agreed on instead of paving was to increase our fees slightly, and lay down reclaim our road in sections each year. We have found this to be very affordable and enforceable under the law. So far, our reclaimed sections are holding up real nice, it's minimizing dust and potholes and is great in the mud season.
