N O T I C E FINDINGS AND DECISION OF THE CITY OF BOULDER BOARD OF ZONING ADJUSTMENT DISPOSITION OF ZONING CASE DOCKET NUMBER BOZ2021-00009 CONCERNING THE APPLICATION FOR A SETBACK VARIANCE REQUIREMENTS OF SECTION 9-7-1, B.R.C. 1981 AT 429 CONCORD AVENUE, BOULDER, COLORADO OF KASSIA BINKOWSKI AND ADAM KNOFF, WHOSE MAILING ADDRESS IS 429 CONCORD AVENUE, BOULDER, COLORADO 80304. On July 8, 2021, the City of Boulder Board of Zoning Adjustment, a quorum being present, held a public hearing, after giving notice as required by law, on the application for the following variance: As part of a proposal to construct a rear 2-story addition and cantilevered deck onto the single-family home, the applicants are requesting a variance to both the east and west side yard setbacks for a principal structure in the RL-1 zoning district in order to meet the combined side yard setback requirements for each side. The resulting east setback will be approximately 5 feet (taken from the new exterior stairs) where 6.8 feet is required and 1.9 feet exists today. The resulting west setback will be approximately 8.2 feet (taken from the new addition) where 13.1 feet is required and 8.2 feet exists today. Section of the Land Use Code to be modified: Section 9-7-1, BRC 1981. Based on our field investigation and the relevant testimony, exhibits, and other evidence introduced at the hearing, and in accordance with the applicable provisions of the Boulder Revised Code, 1981, we find by a preponderance of the evidence that the criteria for granting a variance have been met, and grant the variance as requested: This variance is limited to the use and structure for which it was requested, including the location on the lot and maximum height, as approved by the Board of Zoning Adjustment. This variance was approved by the vote of 5-0. EXECUTED this 8th day of July 2021, effective as of, July 8, 2021. Jill Lester, Presiding Officer of the Board at the Meeting By: ______________ ___________________________ Robbie Wyler, Secretary to the Board of Zoning Adjustment This decision constitutes a final decision as of the date of the hearing at which it was reached. If a variance was granted, the variance expires within 180 (one hundred eighty) days from the date on which it were granted unless a building permit for such variance is applied for within such period.
