1. 424 E. Scott Avenue is a contributing resource to the ONK National Register Historic District and local historic overlay.

2. Repairs and replacement in-kind in patches of the depicted deteriorated wood siding and eave overhang are appropriate within the guidelines. Repair to the masonry foundation and chimney meets the design guidelines; masonry repointing should meet the specifications of Preservation Brief 2 and utilize mortar with a lime content more appropriate for historic masonry.

3. The basement-level window is not a character-defining feature of the house and is not visible from the public right-of-way. Replacement of the window with a secondary access door, including a modestly-sized access platform is appropriate. Applicant should submit the door specifications and details on the proposed door design and guardrail for staff approval.

4. The design guidelines note that replacement roofs "shall duplicate the roofing materials originally found in the neighborhood," including "standing seam metal" cladding. The proposed replacement metal material is an exposed fastener, 36" section metal roof with a.75" ribbed "seam" and two lower ribs. Applicant has referenced 310 and 318 E. Oklahoma as similar roof profiles; both houses are new construction. While a metal roof is appropriate within the guidelines, the metal roof selected should better reflect the profile of standing seam metal roofs that would be originally found in the neighborhood, including a flat panel in between the ribs or seams. Colors should match the specifications of the design guidelines.
