i I delineation., the septic l�l t is within the buffer zone f the coastal bank rather thanonthe coastal bank itself. Ms. Turano-Flores said the coastal bank issue carne up when Bob was concerned about the coastal bank in relation to the septic system and the Board of health's regulation relave to the setback from the top of the coastal bank. The Board of health has preliminarily reviewed this, but hasn't had its full public hearing yet because it would like us to confirm the delineation of the top of the coastal bank More it gives its approval. Mr. Grote said the loo year flood plain has an 11 ft. contour. Michael Talbot said the I lashpee regulation would be one foot higher. Mr. Grot l e said they moved the septic system on the.duly 2& plan to be as far to the unrest as possible. Jack read from Robert gay's leiter of August 19, 2004-afollows: "The locus parcel is well vegetated and consists of the follovwring wetland resources areas: salt marsh, land subject to coastal stornn flowage and coastal bank. It is proposed to develop the lot for a single family home with appearances, portions of which will be built within the coastal bank and land subject to coastal storm flowage. The project as proposed seems to meet the performance standards at 310 CAR 10.30 for coastal banks. LSCSF does not have performance standard ." Michael Talbot said he"s not concerned about the Wetlands Protection Act, but the coastal bank. Ms. Turano-Flores said the conc m expressed at the last full hearing was that the white pine tree located approximately in the middle of where the driveway will go was essentially the only wildlife aspect of the site wording to B aba's last report dated March 15, 2004. She said Mr. Talbot noted that that the vertical layering of the top was to be an extension of a condor of the trees along the edge of the road, and he felt this established what he called a vertical layering. Michael Talbot said he has a picture of that very corridor in the wintertime, which shows that there is a significant amount f canopy. lolls. Turano Flores said in response to that they asked Mr. Schall for a vegetation plan that would recreate that vertical layer by planting four white pines and use Mr. Schall's narrative to establish not only the vertical layering but also a shrub layer within the 35 ft. buffer zone as well as an herbaceous Dyer. Sabatia's conclusion in their March 15th narrative was that this wildlife habitat value on the site was insignificant. She said they believe they have made an improvement to that in suite of the fact that the house v ll now be there. what they are suggesting in the way of plantings vll enhance and wally provide significant wildlife habitat, especially in that 35 ft. buffer zone. Mr. Schall said he had a disagreement with the original Sabatia opinion that the white pine was significant, He would consider that the 35 fL buffer v ith heavy shrub cover be more significant for wildlife. He had recommended a onelo one replacement of the native shrubs not only on this site but the adjacent propenes to the left by replacing some of the bittersweet and honey suckle which are not a native species. He gent into more detail on his suggested plantings. Michael Talbot asked if there is a reason why there were no canopy trees recommended for the 35 ft. buffer. Mr. Schall said there are some in it ,hack said that if we approve the application, Bob recommended having an.oversi.ght of the vegetation for five years. Michael Talbot said for the nine years he has been on this Commission, he has never seem the Commission consider a project which involves to this degree a major alteration of a natural resource area— in this case a coastal bank.
