Note: This section of the Land Development Code applies to lots that are included in a subdivision plat recorded before April 22, 1982 or a tract that is not required to be platted. For the above address the Subdivision Plat was recorded on January 4, 1965 The overall change in IC is from 21.51% to a proposed 20.89% IC, or 8,084 SF IC to 7,883 SF IC, when calculated on a gross lot area basis. BOARD’S DECISION: BOA JULY 12, 2021 POSTPONED TO AUGUST 9, 2021; Aug 9, 2021 The public hearing was closed by Chair Jessica Cohen, Board Member Melissa Hawthorne motions to Postpone to October 11, 2021; Board Member Brooke Bailey seconds on a 10-0 vote; POSTPONED TO October 11, 2021; Oct 11, 2021-POSTPONED TO NOVEMBER 8, 2021 BY BOARD MEMBERS (Due to not enough Board Members present at the meeting). Nov 8, 2021 The public hearing was closed by Madam Chair Jessica Cohen, Board Member Melissa Hawthorne motions to approve with conditions to remove existing wood deck and stairs on the north side as per exhibit E-2/28 and presentation slide E-2/35, and will not exceed calculations on presentation slide E-2/26; Board Member Darryl Pruett seconds on a 11-0 vote; GRANTED WITH CONDITIONS TO REMOVE EXISTING WOOD DECK AND STAIRS ON THE NORTH SIDE AS PER EXHIBIT E-2/28 AND PRESENTATION SLIDE E-2/35 AND WILL NOT EXCEED CALCULATIONS ON PRESENTATION SLIDE E-2/26. FINDING: 1. The Zoning regulations applicable to the property do not allow for a reasonable use because: this site is very large site on top of hill with a subdivision plat from 60s and is state of noncompliance and bringing impervious cover down in order to accommodate the existing structure and moderate improvements, replacing and repairing some retaining walls that are in need in order for structure to remain 2. (a) The hardship for which the variance is requested is unique to the property in that: there is no other lots directly around this area that are encumbered with this slope and the general concerns of having a slope and vehicular and people traffic along the way. (b) The hardship is not general to the area in which the property is located because: the site was platted in the mid 1960’s, no slope category on it at the time and changed to LA overlay. 3. The variance will not alter the character of the area adjacent to the property, will not impair the use of adjacent conforming property, and will not impair the purpose of the regulations of the zoning district in which the property is located because: there is a decrease of impervious cover, some retaining that is going to make it safer place and lessen the slope in some degrees will help the drainage. ______________________________ Elaine Ramirez Executive Liaison ____________________________ Jessica Cohen Madam Chair 3401 RIVERCREST – PROPOSED SIDE YARD AREA E-2/26-PRESENTATION3401 RIVERCREST – SIDE YARD AREA / RAILING E-2/28-PRESENTATIONGENERAL NOTES m o c . e r u t c e t i h c r A d o o w r a G @ o f n i 7 4 7 3 . 0 3 7 . 2 1 5 House Footprint Storage Building Footprint Retaining Wall at Storage Building A/C Pads Wood Deck at House Wood Steps to Upper Wood Deck Upper Wood Deck Stone Patio at House Stone Patio at Pool Wood Deck at Pool Pool Coping Parking Pad Retaining Walls at Parking Pad Driveway Access Drive Guest Parking Area Rock Walls at Guest Parking Area Total Impervious Cover Total Lot Area: 37,498 sq ft 2,409 sq ft 127 sq ft 34 sq ft 18 sq ft 175 sq ft 149 sq ft 142 sq ft 24 sq ft 396 sq ft 54 sq ft 101 sq ft 843 sq ft 88 sq ft 292 sq ft 1,558 sq ft 1,521 sq ft 133 sq ft 8,064 sq ft EXISTING IMPERVIOUS COVERAGE CALCS EXISTING AREA AREA DESCRIPTION EXISTING IMPERVIOUS COVERAGE CALCULATIONS PER ZONE IMPERVIOUS COVER ZONES BASED ON SLOPE MAP SYMBOL LOT SQUARE FOOTAGE PER ZONE ALLOWABLE PERCENTAGE PER ZONE MAX ALLOWABLE SQUARE FOOTAGE PER ZONE EXISTING SQUARE FOOTAGE PER ZONE EXISTING PERCENTAGE PER ZONE NEW IMPERVIOUS COVERAGE CALCS AREA DESCRIPTION EXISTING AREA NEW IMPERVIOUS COVERAGE CALCULATIONS PER ZONE IMPERVIOUS COVER ZONES BASED ON SLOPE MAP SYMBOL LOT SQUARE FOOTAGE PER ZONE ALLOWABLE PERCENTAGE PER ZONE MAX ALLOWABLE SQUARE FOOTAGE PER ZONE SQUARE FOOTAGE PER ZONE PERCENTAGE PER ZONE 00% - 15% >15% - 25% >25% - 35% >35% TOTALS 10,348 sq ft 4,209 sq ft 1,451 sq ft 21,490 sq ft 37,498 sq ft 35% 10% 05% 00% 3,622 sq ft 421 sq ft 73 sq ft 0 sq ft 5,537 sq ft 2,285 sq ft 64 sq ft 178 sq ft 4,116 sq ft 8,064 sq ft 53.51% 54.28% 4.41% 0.83% 21.51% 00% - 15% >15% - 25% >25% - 35% >35% TOTALS 10,348 sq ft 4,209 sq ft 1,451 sq ft 21,490 sq ft 37,498 sq ft 35% 10% 05% 00% 3,622 sq ft 421 sq ft 73 sq ft 0 sq ft 4,931 sq ft 2,037 sq ft 258 sq ft 607 sq ft 4,116 sq ft 7,833 sq ft 47.65% 48.40% 17.78% 2.82% 20.89% GARWOOD a r c h i t e c t u r e 2021 © ALL DRAWINGS AND DOCUMENTS, AS INSTRUMENTS OF SERVICE, REMAIN THE PROPERTY OF GARWOOD ARCHITECTURE, PLLC.
