Exterior rehabilitation to porches.

Covered porch on west elevation: metal porch supports and handrails to be removed. New porch supports to be 6 by 6 square posts, located at the roof corners and centered on the west elevation, and porch to be enclosed with screen. New screen doors to be installed on north and south sides of enclosed porch.

Deck on façade: existing non-historic deck to be removed and reconstructed with a similar rectangular footprint, extending the full length of the façade, extending an additional 5' into the front setback. The deck is proposed to be constructed with a composite flooring material (TimberTech Composite, Prime Collection) with an aluminum handrail of simple square posts.

CONDITIONS OF APPROVAL PER 10/17/24 HZC MEETING: 1) any deck screening to be compatible with existing house, with details provided to staff for review.

1. 10729 Lake Ridge Drive is a contributing resource to the Village of Concord NRHP district and local HZ overlay.

2. The house is oriented with a side elevation fronting Lake Ridge Drive and a front door facing Spring Street, despite the address oriented to Lake Ridge Drive. The work proposed relates to existing porch and deck features on the house.

3. While enclosing a porch visible from the street is discouraged, installing screening does not fully enclose the porch. Removal and replacement of the non-historic iron porch support and railing is appropriate, and the 6" square posts will be more compatible with the overall design of the house.

4. Design guidelines recommend that porches feature wood materials for ceilings, floors, posts, and columns. Composite porch decking has been approved in other historic districts, especially on uncovered decks or porches, typically including conditions that the flooring materials are tongue-and-groove style and use a smooth finish instead of faux wood graining. In this instance, the porch and deck flooring will not be visible from the right-of-way, due to the elevated height of the floor and the new screening proposed for the side porch. The proposed product is appropriate for the house and the context.

5. The current deck foundation is enclosed with a wood lattice screening. New deck screening should be compatible with the materials and design of the existing house, and the applicant should provide information on foundation screening to staff for approval.

6. The porch and deck currently feature two different railings, one iron and one wood, of different heights. Installing one consistent guardrail across the porch and deck will create a more consistent effect. The thin aluminum balustrade will have a less significant visual impact than the current wood deck railing.
