MINUTES OF THE <br /> ORONO CITY COUNCIL MEETING <br /> Monday, September 14,2020 <br /> 6:00 o'clock p.m. <br /> they will need to clear cut a larger area to accommodate that grading issue. He thinks this is the reason <br /> the 18%limitation is there and why dry buildable is so important. <br /> Johnson asked what Barnhart's concern is with utilizing 22.5. <br /> Barnhart replied he doesn't have any information to suggest that it is too much or too little, he hasn't done <br /> the analysis. He thinks 18%is where they should go. <br /> Johnson noted to do a walk out basement, it's typical to have 22.5%grade. <br /> Barnhart said he doesn't know if it's typical, it can happen, and he doesn't know what typical is. <br /> Johnson said perhaps it's reasonable. <br /> Barnhart clarified he doesn't believe he has any information to suggest that they depart from 18%. <br /> Crosby said not to waver from Barnhart's point, but if there isn't an argument to not look at it or look into <br /> it, or the difference,why wouldn't they. <br /> Barnhart said other than one developer or surveyor saying he has an issue in this one isolated situation, he <br /> needs more to just open up the entire code and dig into every single standard. <br /> Johnson asked of the five surveyors Barnhart sent it to, how many responses he received from the <br /> surveyors. <br /> Barnhart replied he got one response. <br /> Johnson noted it's 100%of their response. He noted the response said a typical walkout house drops 9 <br /> feet in 40 feet,which is 22.5% slope. Johnson said if you think about a walkout and that is 22.5%slope, <br /> it seems reasonable to him to count up to 22.5%and asked what they are guarding against by using the <br /> potentially arbitrary number of 18%. <br /> Barnhart responded the 18%has been there since before they started and he's unsure what started it. He <br /> said to keep in mind they don't do dry buildable calculations at the time of building permit, and they've <br /> never used the calculation at a walkout basement. <br /> Johnson said when someone is under the zoning side, if they purchase a vacant lot,the City would <br /> exclude any slopes or bluffs over 18%in the calculation dry buildable for how much hardcover they can <br /> have,as an example. <br /> Barnhart said he's doesn't know if hardcover excludes dry buildable,but the City would in theory use the <br /> dry buildable calculation to determine the lot size when looking at the dry lot area variance,for example. <br /> Walsh asked if people have the opportunity to grade the area if it was 22%to bring it to 18%to get more <br /> dry buildable. <br /> Page 19 of 26 <br />
