Location
100 N Central St

Including 106 N Central Street


Applicant Request
106 N. Central Street - Demolition of the 1 story building.

100 N. Central Street (two story building) - Replace the existing non-historic windows on the second story with historically appropriate one-over-one windows. Restore the street level façade to its earliest documented state. Remove the existing stucco on the first floor and clean and repoint the brick as necessary. The existing continuous beam will be re-exposed and all existing windows will be professionally restored to their like-new condition. Remove internal egress stairs that lead to the door between the two storefronts and add a new internal egress stair. Close openings on the north elevation that connected the interiors of 106 & 108 N. Central Street. The filler wall for the closed openings will be clad with painted cement siding and inset from the exterior brick wall. The cement siding will be the same as that of the proposed addition. Create two new window openings on the ground floor of the rear façade, facing the courtyard. See sheets D3 and D4 for additional information.

100 N. Central Street (corner building, formally known as Patrick Sullivan's) - Repair existing stained glass windows and large storefront windows on the first floor where feasible and restore and repaint all historic windows on the first and third floor (small arched windows in the turret). Replace non-original one-over-one windows on the second story with historically appropriate one-over-one windows. Re-construct the parapet at the back of the Sullivan's building in the same design to be plumb. All decorative elements on the building will be cleaned and repainted. The double door on the Jackson Avenue (toward the rear of the building) will be replaced with doors of the same design with louvers infilling the panel of the doors. See sheet D5 for additional information. UPDATE (APPROVED by staff, 9/13/2013): Structurally stabilize the parapet wall in its current state versus rebuilding it. The stabilization will incorporate a 3/8" threaded rod at 48" filled with epoxy grout.

Addition - The addition will be constructed behind and attached to 100 N. Central Street. It will not be visible from the street. The addition will be two stories and clad with painted cement siding. Replace the existing egress metal stair between the addition/100 N. Central Street and the adjacent building that currently exits into the courtyard, with a new stair that exits on Jackson Avenue. The landing is behind a wrought iron gate, which will be replaced with new wrought iron gate. See sheet D4 and D6 for additional information.

Courtyard - The existing courtyard for the Sullivan's property will be removed and a new courtyard design will take its place. There will be wrought iron fencing, brick pillars and walls with concrete caps that enclose the courtyard. There will be two gates for code compliant egress exits. The courtyard will include square concrete pavers and vegetation strips as shown in the attached plans. The concrete pavers will be easily removed in necessary for future designs. See sheets D6, D7, D8 and D9 for additional information.

Staff Comments
----------------------------------------------------------- COMMENTS FOR THE JULY 17, 2013 BOARD MEETING ----------------------------------------------------------------
The Historic Resources section of the guidelines apply to these structures because 100 N. Central Street (corner building, formally known as Patrick Sullivan's) is in the Jackson Avenue Warehouse (National Register) Historic District and 100 N. Central (two story building) & 106 N. Central Street (one story building) are in the Southern Terminal and Warehouse (National Register) Historic District. Both the two story building & 106 N. Central Street are listed as non-contributing structures.

In regard to the demolition request for 106 N. Central Street, section 1.C.12 of the guidelines states "Allow demolition of existing buildings or additions that do not contribute to the district, evaluated on a case-by-case basis". The structure is circa 1925 but has been altered beyond reasonable means of restoration or repair.

With the proposed restoration of the storefront at 100 N. Central Street (two story building), this structure could potentially be considered contributing to historic district in the future since the original description noted the alteration to the storefront as a reason for its non-contributing status.
