Washington’s Historic Preservation Commission is scheduled to consider three request for major works in the Historic District during its meeting tonight.

The commission is slated to consider a request by William Kenner to install a 3.5-foot-high fence at the rear of his property, install safety rails on the wrap-around porch and install operable shutters on the front façade of his property at 720 E. Main St.

Sloan Family Ventures is seeking permission to remove the roof and support columns from the rear of the building at 245 W. Main St. and replace them with an awning.

Rachel Mills is seeking permission to expand the rear porch on her property by eight feet so it matches the rear façade of her house in width. Mills’ house is at 409 E. Main St.

Under the commission’s rules, requests for major works come before the commission for approval. Requests for minor works are handled by the city’s planning staff, but they come before the commission for review. The commission, when it approves a major work, issues a certificate of appropriateness for the project.

The following minor-works requests have been received:

• A request has been made by the property owner at 720 E. Main St. to change out the HVAC system.

• A request has been made by the property owner at 114 E. Main St. to replace the heating system with a new HVAC system.

• A request has been made by the property owner at 117 N. Market St. to replace the roof with a new TPO membrane system.

• A request has been made by the property owner at 210 E. Main St. to replace rotten railings and balusters with new and matching historic exactly.

• A request has been made by the property owner at 102 Stewart Parkway to change out the old HVAC system and replace with a new system.

• A request has been made by the owner of 406 E. Main St. to change out the HVAC system in six units with new systems.

• A request has been made by the owner at 322 E. Main St. to change out the gas pack system.

The City of Washington governs land use and building activities in the Historic District to protect the area’s historic and cultural resources. The goal is to discourage development or alterations that would not be in keeping with the historic period these buildings represent. People who live in the Historic District can be assured that the uniformity of the houses and character of the neighborhood will not change.

The commission, following established policies and guidelines, rules on proposed changes, additions and other modifications to structures in the Historic District. The commission also helps enforce the city’s demolition-by-neglect ordinance, with the goal of preserving historic structures instead of seeing them demolished when possible.

The commission meets at 7 p.m. today in the Council Chambers of the Municipal Building, 102 E. Second St.
