42 182 resenroirs on the Eno River. Protect the natural areas of associated feeder streams. The decision to keep this for purposes of 183 environmental protection of Seven Mile Creek,Crabtree Creek and Rocky Run,that is something the board should say,yes that 184 is one of the criteria. Sometimes we would end up with a little island between all our rules and we suggested that if do all our 185 half mile buffers all over,there is some isolated criteria and we suggest even though that does not meet the half mile definition, 186 we suggested putting that in there. One of our commissioners said that just because it is ease of administration, should you 187 include that in a critical area designation or just allow it the way it is. I would like you to decide on that tonight or in April. This is 188 what staff was saying should be critical, why, because it is surrounded by critical. Should the private properry rights of the 189 eo le in that area,should the be allowed to ut one unit er acre. P P Y P P 190 191 Mary Bobbitt-Cooke: It will still be protected? 192 193 Craig Benedict: Yes. 194 195 Mary Bobbitt-Cooke: The difference between protected and critical as I read it was rather small. 196 197 Craig Benedict: Yes. Half the impervious, 12%to 6%and from two units per acre to one unit per acre. As we said in the 198 hearing,the typical density of this entire area is over two acres per unit because that is the way it has been developed. I have 199 not seen any subdivisions that have been,on the average,under two acres per unit. 200 201 Mary Bobbitt-Cooke: The Bluffs? 202 203 Craig Benedict: The lots are 1.3 acres but the total density is over two units per acre. 204 205 Mary Bobbitt-Cooke: If you take all the land? 206 207 Craig Benedict: Yes. You will see in the Bluffs,the densiry is the overall. Typically,the Bluffs had more fields,as one of these 208 parcels down here that had some controversy associated with it because there is ridge line here and with this development flow 209 into that the way it is now,the Seven Mile Creek area or will it flow to Rocky Run which wasn't listed as a critical area. That is 210 why we have to correct this so we don't run into a case by case. 2ll 212 Mary Bobbitt-Cooke: I had to go back to the mention of protect natural areas which in some ways is different than protect quality 213 of water and I think it is a very important discussion about protecting natural areas. I don't think we are giving it due diligence 214 because we are trying to get this in under water quality. I don't like to kind of mad dash this together but to take it out and have 215 an in-depth discussion about natural area so we really understand what we are protecting and then protect it in a way that it has 216 more to do with environmental protection. 217 218 Craig Benedict: Presently, we have more latitude with zoning regulations. The state gives us more power for water qualiry 219 reasons so we use that umbrella of state watershed rules to both protect water quality areas and as a secondary and possibly 220 equal benefit are natural areas because it has its own purposes. We are using that umbrella but it has dual proposes but I think 221 in our discussion,we are seeing that in this case,this is of equal importance,as is the water quatity issues. 222 223 Larry Wright: Craig,what do you have to present and I see there is quite a bit here,I think we really need to move forward. 224 225 Mary Bobbitt-Cooke: Can I request that at the next meeting,we talk about the natural areas . The other thing is this map here 226 is not aligned with the map with the purple line. 227 228 Craig Benedict: We are going to go back to the questions to find out where you want to go with these issues, protect the whole 229 reservoir,shrink them down to a different size. 230 231 Larry Wright: Can we have just a very short review of what we are supposed to be doing? 232 233 Craig Benedict: We need to make the map match the definitions. I don't think there is any latitude;we have to include the state 234 critical areas. 235 236 Earl McKee: Talking about your state critical areas,going back to the drawing of the ridge line,the state critical areas would be 237 defined as half mile or to the ridge line,whichever is chosen or actually whichever is the closest,is that correct? 238 239 Craig Benedict: Whichever is closer. The state has a watershed definition,this is actually a sub watershed because the actual 240 watershed changed where this is lower Eno unprotected. That is the definition we use for the ridge line of the watershed. The 241 ridgeline of the sub watershed goes here. Those definitions have to be very specific. There is 13 watersheds here, this is an 242 Upper Eno Watershed, Little River Watershed, Flat River, there are 13 of these designated watersheds so if that is the
