suction mechanism, thus creating a possible surface water problem for the neighboring lots. In my opinion, this concern has no merit. In my 20 years of engineering experience on the Big Island, 1 have never seen this occur when the subsurface has the porosity of this site. In my opinion, the likelihood of the neighbor's concern to materialize is nearly zero. Sight Distance Sight distance is the distance a driver can see to his or her left and right down Kinoole Street when sitting in his or her car at the exit of the property. Sight distance standards are set by the American Association of State I fighway and Transportation Officials (AASHTO). The required distance is based on the design speed of the road and characteristics of the design vehicle, which have been set by AASHTO. For this site, the required sight distance to the right toward Kawili Street is 500', and the required sight distance to the left toward Puainako Street is 430'. The sight distance needed to take a right turn or a left turn into the property is less than the sight distance needed to exit the property. So if the sight distance for cars exiting the property is adequate, then so will be the left and right turns into the property. I have surveyed the grade of the line of sight up and down Kinoole Street and have plotted the profile of the street and sight distances. (See attachment 5). I have determined that the required sight distances are met. Additionally, I have sat in my car at the proposed exit of the site and have visually confirmed that the sight distance is adequate. Therefore, AASHTO sight distance standards can be met for this project for right and left turn in and for right and left turn out. (ti
