Staff Recommendation

Staff recommends approval of 2-A-21-IH with the following conditions:
1) Parking should meet City Engineering requirements, be located at least 20' behind the house's front façade, and utilize gravel or permeable pavers as necessary to stay within impervious surface requirements;
2) Use a gable vent on the front gable field and clad the foundation in stucco;
3) Additional windows on the left elevation;
4) Meet City Homemaker requirements for visitability with a ramp or a zero-step entry on one elevation;

Applicant Request
New Primary Structure
1. The proposed front setback of 20' to the full-length porch and 28' to the main massing of the house is compatible with the average front setback of 23.7' on the block. 1537 Minnesota Avenue, the adjacent new house reviewed in January 2020, will be in the same range. The site plan includes a walkway from the front door to the street.

2. The one-story, three-bay house is proportionate to the dimensions of the lot and the other houses on the block. The side yard setbacks are consistent with the block, where most houses are closer to the side property line to accommodate driveways.

3. The alley behind this block of Minnesota Avenue is not operable, so parking will need to extend off Minnesota Ave. The parking pad should be at least 20' behind the front façade of the house. Gravel or permeable pavers may be used to stay within impervious surface limits.

4. Overall, the three-bay front façade is similar in scale to other houses along the street. The 8/12 pitch roof contributes to the overall massing of the house. The 1' tall foundation is comparable to the neighborhood context.

5. The full-length, recessed porch is sufficiently deep to match the design guidelines and will be differentiated from the previously reviewed infill houses on the block. The details of 6 by 6 square columns with bases and trim, and a square picket railing, are appropriate within the guidelines.

6. Additional windows should be added to the left elevation to compliment the house's pattern of solids to voids.

7. The 8/12 pitch roof is appropriate for the historic context. Metal roofs are not excluded in the design guidelines, though they are less frequently used. Guidelines encourage darker shades of roof cladding to reflect historic context. A vent detail in the front gable field would contribute additional visual interest.

8. Hardie Plank lap siding and shingles are an appropriate siding material. The foundation should be parged or stuccoed on all elevations.

9. The final site plan should incorporate one native or naturalized shade tree in the front and rear yards.

10. Final drawings should incorporate a ramp or zero-step entry to meet City Homemaker program requirements

Staff Comments
New primary residence fronting Minnesota Avenue. One-story residence measuring 24' wide by 50' long, featuring a front-gable roof and a full-length, 8' deep porch recessed under the primary roofline. House will be set 20' from the front property line from the porch and 28' from the main house. Access proposed to extend from Minnesota Avenue, as there is no operable alley behind the property. A concrete walk extends to the front property line from the door.

The house features precast concrete walls clad in fiber cement lap siding (Hardie Plank), with an 8/12 pitch front-gable metal roof, and a 12' tall foundation. A full-length, 8' deep porch is recessed under the primary roof gable. The porch is supported by 6 by 6 square columns with a square picket railing.

The façade (south) elevation is three bays, with two 1/1 double-hung windows flanking a half-light door. The gable field will feature Hardie shake siding. (written on application, not depicted on elevation drawings) The left (west) elevation has one 1/1 double-hung window. The right (east) elevation features two 1/1 windows and a secondary entry door.
