BACKGROUND DATE OF CONSTRUCTION: 1926 ZONED HISTORIC PRESERVATION: 1994 NATIONAL REGISTER LISTING: SWAN LAKE; 1998; ADDITIONAL DOCUMENTATION 2009 CONTRIBUTING STRUCTURE: YES PREVIOUS ACTIONS: COA NOVEMBER 8, 2012 TPC APPROVAL Construct natural stone retaining wall along west and south sides of front yard COA JANUARY 20, 2015 STAFF APPROVAL Replace existing crumbling sidewalk and steps with new sidewalk and steps to match Construct decorative iron fence with gate along west and partial south yards C. ISSUES AND CONSIDERATIONS 1. Construct Hackett stone retaining wall around west and south side of property i. The applicant requests to construct a retaining wall using Hackett stone along the west and side yards of his property. The applicant stated the yard s slope has destroyed two lawn mowers in three years and much of the yard washes into the sidewalk. The applicant believes a retaining wall will increase his use of the yard, have curb appeal, and can allow his dogs to use the front yard untethered. ii. The applicant was continued from February 12, 2015 TPC Meeting and the April 9, 2015 TPC Meeting. On the April 9 meeting, the Commission recommended using cut stone instead of rough stone to increase the wall s life and requested the applicant to research other materials. i.

2 COA SECTION G GUIDELINES FOR LANDSCAPE FEATURES, PAVING AND SIGNAGE G.1 Landscape Features G.1.3 Ensure that new landscape features are appropriate to the style of your home and consistent with the historic elements found along the same street and within the district. G.1.5 Use wall materials that are consistent with the historic walls found along the same street and within the district. Cinder block, segmental retaining wall systems, corrugated metal, and railroad ties are not allowed. Historically styled cast concrete block will be considered on a case-by-case basis. ii. Item 1 Considerations 1. Several properties along the same street feature dry stack walls including: 1607 S. Norfolk Ave., 1704 S. Norfolk Ave, and 1718 S. Norfolk Ave. 2. Sandstone appears to be the most common stone used throughout the street instead of limestone. 3. The applicant was approved for a natural stone wall in Since he did not use his permit within the two years, he was obligated to have his project reviewed before the Commission again. Page 2 of 2
