Applicant Request
Driveways, parking pads, access point, garages or similar facilities
1. The house is proposed to be set 28.6' from the front property line. The average front setback of the block is 24.9', with the adjacent house at 26'. The front setback is recessed behind the average due to the location of power lines at the front corner of the property. The site plan includes a walkway to the street.

The side setbacks have been revised in response to building code requirements, and the building footprint and façade width has been revised accordingly.

2. The block to receive new construction is characterized by Queen Anne houses with similar massings as the proposed new construction. The proposed 1.5-story, four-bay house is proportional to the dimensions of the lot and the context of the block.

3. The proposed parking meets the Infill Housing design guidelines as it is located to the rear of the property and accessed from the alley. Final site plans may be necessary to meet City Engineering standards.

4. The façade is similar in scale and width to the context, and the house features a foundation height compatible with the context.

5. The 8' deep, partial-width front porch recessed under the primary roofline meets the design guidelines.

6. Guidelines recommend windows and doors styles similar to historic houses on the block, with similar placement and ratio of solid to void. As proposed, there are no windows on the left elevation. The left elevation will be somewhat visible from the street as the site plan has been revised to set the elevation 5' from the interior side property line; windows should be added to the left side elevation.

Related to the base zone, in the CN zone, building facades along a public right-of-way must not contain blank wall areas that exceed 30 linear feet. The front façade must maintain a minimum transparency of 30%. This requirement can be waived by the DRB via issuance of a COA, based on the fenestration patterns being appropriate for a house.

7. The 6/12 roof pitch meets the design guidelines.

8. The applicant has clarified the house will be clad in lap siding with a stucco-clad foundation.
