Commissioner Balch stated that he would like to go a little further, that the applicant's position is that the addition of a road is significant grading. He asked staff to go into the definition of"significant": "How significant is 'significant' on grading?" Mr. Dolan replied that he believes the applicant has estimated 11,000 cubic yards. He indicated that the Commission could ask one of their team to come up because they have done a little bit of work on it, although they do not have a design. He asked if that number is going to mean anything to the Commission. Chair Allen replied that it will not mean anything to her except if someone helps to translate it. Commissioner Balch stated that his concern is grading because if grading is significant, it would violate his principle of upholding Measure PP, if the mass destruction of the hillside occurs because of trying to put in a road. Mr. Dolan stated that the applicant confirmed that it would be 11,000 cubic yards without the retaining walls. Commissioner Nagler inquired if the 11,000 cubic yards would start about % the way up the hill and grades down to the base, but as far as up the hillside, it would stop at the ridge of trees that is up towards the top. Mr. Dolan replied that there would be some above and some below. Commissioner Balch stated that he has no idea what 11,000 cubic yards of fill looks like. He asked staff how much fill was put in for the Bernal Phase II project. Mr. Dolan replied that he cannot tell that, but there is a graphic which shows the layout and the extent of grading in the EIR when it talks about the alternatives: Figure 5-3 on page 5-23. He indicated that the road is visible; there is a dash line that says "limited grading" and talks about how much cut and how much fill. Commissioner Balch asked staff what the scale is and if each significant major line is 50 feet or less, because 470 feet looks like towards where the retention basin would be. Mr. Dolan said it is 10. Commissioner Balch clarified that for each major line, it is 10 feet down topography-wise; so it looks like they are altering approximately where the arrow comes in with the preliminary earthwork paralleled on the right bound; and on the left bound is approximately 1/4 inch from the property line on major line 470 on the left. Mr. Dolan stated that it looks like grading will be over an elevation change of 70 feet. Commission Balch asked that the graphic be displayed, showing where the grading would be. He then pointed to the road that goes up to Sunset Creek Lane. Commissioner Nagler inquired if this is to avoid a retaining wall.
