Conditions approved at June 2020 HZC Meeting: 1) use mortar more appropriate for historic bricks, type O or type K depending on age of masonry; 2) front door specifications be submitted to staff for approval; 3) a metal roof be selected that better resembles historic standing seam metal originally found in the neighborhood, with a color to meet design guidelines, with approval by staff.
Two story frame with wood shingle wall covering. Hip roof with asphalt shingle covering and square awn wood attic vents. Double hung one over one windows.

1. 238 E. Oklahoma 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 cedar shakes are appropriate within the guidelines. Repair to the masonry foundation, including reconstruction of one section of foundation wall with existing bricks and repointing appropriate mortar meets the 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 front door is a non-historic modification and replacement with a door that better fits the house's design is appropriate. Specifications on the proposed replacement door should be submitted to staff for review.
4. The porch to be enclosed is located at the rear of the house and not visible from the public right-of-way. The right half of the hipped-roof massing is already enclosed. Enclosure with three adjoining single-light windows and wood clapboard siding is appropriate within the guidelines, and a difference in siding serves to differentiate the enclosed sunporch from the existing house. The height of the single-light windows as depicted maintains transparency.
5. 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 three-quarter-inch 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.
