Individual trees or 7 groups of trees to be preserved outside the buffer area shall be fenced at no less than 8 75% of the area within the drip line of the critical root zone and shall be flagged with 9 bright orange vinyl tape wrapped around the main trunk at a height of four (4) feet or 10 more such that the tape is clearly visible to workers on foot or operating equipment. 11 (e) The city official may allow minor modifications of the plan to alleviate 12 particular problems during the process of construction. In reviewing a request for 13 modifications, the city official may require from the applicant's engineer, architect, or 14 landscape architect appropriate reports and data sufficient to make a decision on the 15 request. 16 (f) Major changes to plans approved by the planning commission either in sketch 17 or final form shall only be permitted by the planning commission. Examples of major 18 changes are those that substantially increase the height of cuts or the area of clearing or 19 grading, or substantially impact neighboring properties. More than twenty percent 20 (20 %) increase in height, area or impact will normally be considered a major change. 21 Examples of increased impact include reductions in buffer area, increased runoff onto 22 adjacent properties, and increased site area that is visible from adjacent properties or 23 public streets. 24 Sec. 29 -190. Grading and drainage plan requirements. [PAGE 19 OF 281 1 Preparation of grading and drainage plans shall follow the stormwater 2 management and drainage manual and shall be designed on the basis of the following 3 considerations: 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 (1) A maximum of thirty (30) vertical feet of fill or excavation (such as three, ten [10] feet vertical terraces or two, fifteen [15] feet vertical terraces) is permitted, however additional development areas may be constructed a minimum of one - hundred fifty (150) feet in width and at a slope of no more than eight percent (8 %). The maximum of thirty (30) feet of fill or excavation may again be utilized. a. The depth of fill or excavation shall be measured from the finish grade elevation to the original ground line elevation. b. No more than two hundred (200) feet of terrace can be in a straight line and a minimum of a ten (10) feet curved section, jog, or offset is required for each additional two hundred 200 feet of terrace. C. For excavations or fills constructed with slopes flatter than 3:1 (three horizontal to one vertical), terraces are not required nor is there a limit on the height of cut or fill. Planting requirements on these 3:1 slopes shall be the same as required for terraces and shall be spaced uniformly over the slope.

A properly sized sediment 12 basin is required for each separate drainage area within the property being developed. 13 (12) Construction access shall be limited to locations as approved by the city 14 official. Construction access points shall be paved in uniformly graded stone without 15 fines for a minimum length of twenty percent (20 %) of the lot depth or fifty (50) feet, 16 whichever is greater, up to a maximum of one hundred (100) feet to prevent tracking 17 onto the city street. 18 (13) Appropriate provisions such as the addition of water or dust retardants shall 19 be utilized to prevent excessive particulate matter from becoming airborne. 20 (14) A perimeter buffer strip shall be temporarily maintained around disturbed 21 areas for erosion control purposes and shall be kept undisturbed except for reasonable 22 access for maintenance. The width of the strip shall be six percent (6 %) of the lot width 23 and depth. The minimum width shall be twenty -five (25) feet and the maximum shall 24 be forty (40) feet. In no event shall these temporary strips be less than the width of the 25 permanent buffers required for the development. [PAGE 23 of 28] 1 (15) A minimum strip twenty -five (25) feet wide, undisturbed except for 2 reasonable access, shall be provided along each side of streams having a ten (10) year 3 storm of greater than one hundred fifty (150) cubic feet per second. The twenty -five 4 (25) foot strip shall be measured from the top of the bank. An exception to this 5 requirement is allowed where the only work being done on the site is public street 6 construction. 7 (16) Care shall be exercised to minimize the risk of damage from or to pedestrian 8 and vehicular traffic in the vicinity of a cut or fill by placement of handrails, guardrails, 9 fencing or landscaping. 10 (17) Additional landscape treatment shall be provided in accordance with chapter 15 11 of this code. 12 Sec. 29 -191. Unified plan and permit. 13 One plan may be submitted incorporating all provisions for compliance with the 14 applicable city zoning, landscaping, drainage detention, grading, clearing, filling, 15 cutting, quarrying, and construction requirements. 16 Sec. 29 -192.
