Updates for 4-B-20-IH

4-B-20-IH

Driveways, parking pads, access point, garages or similar facilities
Site Info

The applicant is proposing a new driveway and shed in the rear yard of the property. 1. A new driveway is proposed off the alley, 10-ft wide x 17.5-ft long. The amount of impervious surface is a concern due to the size of the lot. To address this, the applicant is considering either using drivable grass with native cover or a ribbon driveway. 2. The driveway will have a double-gate that aligns with a new privacy fence in the back yard. 3. New shed near the edge of the alley is proposed 5' from the rear lot line and 5' from the adjacent neighbor in the rear west corner of the lot. a. Tuff Shed is the vendor of the shed; it will be a 10' x 12' structure with a 6:12 single gable roof. b. Shed will be painted "Smoky Slate" and the trim will be "Delicate White". c. Shed will be clad in vertical siding and will feature a barn-style door facing the interior of the lot. d. The shed will rest on 4 concrete piers. 4. Extensive landscaping, a fence in the rear yard, and a rear patio are proposed but are not the purview of this Committee.

Staff Recommendation

1. The shed location meets the base zone (RN-1) setback requirements for accessory structures. 2. The Infill Guidelines are largely silent when it comes to the aesthetics of accessory structures. Guidelines on materials, doors, etc. are for primary structures. 3. Alley access should be utilized when a functioning alley is present, so the driveway location meets the Infill Housing Guidelines. 4. The driveway will need to meet the City's Engineering Department requirements: a. The driveway and parking area must provide parking for a minimum of 1 vehicle since there is an existing front driveway. A driveway of less than 18 feet wide must be 35 feet in length. b. The gate must be at least 5 feet off of the property line, and must swing in towards the property and not out towards the alley. c. If the applicant decides to go with the wheel tracks driveway, he will need to utilitze 3-ft wide wheel strips, with a grass strip of 4 feet wide in the middle. We also need a solid surface (asphalt or concrete) in the right of way that connects to the alley or street the full width of the driveway.

Actions from the April 2, 2020 meeting

4-A-20-IH Approved

1. The addition, while sizable, is located at the rear of the house. The Infill Guidelines allow larger additions provided they are to the rear of the house to keep the original scale of the front faҫade consistent with other houses on the block (p.14). 2. The windows and roof materials selected are like those original to the house (p. 14). 3. The roof line has a slope similar to the original roof (p. 14). 4. Windows on the addition have a balanced solid-to-void ratio (p.10). 5. The exterior covering is not the same as the original material of the house. However, the sides have recently been resurfaced with 4' x 8' Hardi-panels with grooves to simulate siding and placed vertically. Replacement of exterior building materials is not regulated by the Infill Housing Guidelines. The Guidelines only cover materials with regard to new construction or additions. Therefore, since the Committee has no authority over the building materials on the existing structure, staff recommends approval of the vertical siding so that it is consistent with the rest of the exterior.

4-C-20-IH Approved

The proposal is in compliance with Infill Housing Design Guidelines.


4-D-20-IH Approved With Conditions

Conditions: 1. Utilize horizontal lap siding beneath both gables to more closely resemble the exterior materials used on Ranch style homes and those historically utilized in the neighborhood. The siding should have a wide reveal (7 — 10 in) to be consistent with Ranch style architectural materials. Reasons: 1. The house can be characterized as a Transitional Ranch House. Front porches are not common to Ranch style houses; they mostly feature stoops or entries that are unobscured. There is not a lot of guidance in general regarding porches for this architectural style (p. 9). 2. The Infill Guidelines state that the addition of a porch to a Ranch-style house may be acceptable in some 1930-1950 era neighborhoods. While the Oakwood neighborhood is not from this era, several of the houses on this block are (p. 9). 3. Guidelines recommend an 8-ft porch, but since the proposal is to add a porch over an existing patio slab, staff finds the 6-ft depth acceptable. It is unclear when the patio was added. Historical aerials from the early 1980s show the patio; aerials from earlier decades are too blurry to read are (p. 9). 4. The front setback of the primary structure will not change, as the front exterior wall will remain as is. The front setback of the porch will be approximately 20 ft. This is similar to that of other front porches on the street. (Front setbacks of the primary structures with porches average approximately 20 ft. Front setbacks of porches average approximately 17 ft.) 5. The open, decorative trusses proposed are not consistent with architectural characteristics of a transitional Ranch-style house. 6. Vertical siding is not permitted per the Infill Housing Guidelines are (p. 13).
