CLEVELAND PARK-WOODLEY PARK

ANC 3C recently issued a press release commending the D.C. Zoning Commission's unanimous vote Oct. 1 to begin holding public hearings in January when it considers establishing new zoning categories to protect the low-scale character of commercial areas in Cleveland Park and Woodley Park.

In another matter, the commissioners, prompted by community concern over the planned closing of a neighborhood grocery store, also voted unanimously Sept. 28 to support the Supermarket Tax Incentive Act of 1987, introduced to the City Council by councilmember John Ray (D-At Large). The bill proposes to offer tax incentives to grocery stores with a low profit margin to help them remain in the city's high-priced commercial real estate market.

Opponents of the planned Nov. 28 closing of the Safeway grocery store at 3427 Connecticut Ave. NW collected the signatures of more than 6,000 citizens on a petition calling for the store's owners, city officials and community leaders to take whatever steps are necessary to keep a grocery open at that location.

Also at the Sept. 28 meeting, ANC 3C commissioners passed a resolution asking City Council Chairman David Clarke to hold public hearings on the D.C. Anticorruption and Fraud Act of 1987, a bill recently introduced by council member Carol Schwartz (R-At Large) that is designed to prevent possible corruption by city officials. Schwartz described the program to commissioners at the meeting.

The commissioners also voted to draft a letter to the Swedish ambassador expressing the ANC's concerns over the Swedish government's plans to demolish the Macomb Mansion at 3415 Massachusetts Ave. NW to build a larger chancellery for about 65 embassy employes there. The mansion now houses the Embassy of Cape Verde. The ANC objects to the proposed demolition of the historic mansion and is concerned that a larger office building in the neighborhood would lead to increased traffic and parking problems.

Residents of ANC 3C, where the property is located, have been battling the planned opening of two roads on the property included in the act.
