Flagpoles in San Francisco

A small, dense city of offices, hotels, hospitals and hill neighbourhoods with water on three sides of it. We cover San Francisco and the San Francisco County area, including the Financial District and Montgomery Street, SoMa and Mission Bay, Union Square, the Embarcadero and Fisherman's Wharf, Civic Center, the Presidio, the Marina, the Mission, Nob Hill and the UCSF campuses.

Wind here. San Francisco sits in an exposed, salt-laden urban area, which works out to roughly 95 mph under the code your town uses. That figure decides how wide and how thick the pole has to be, so we check it against your address before we quote. The mapped figure is not what a downtown pole actually stands in. The city takes street-level wind seriously enough to write it into its own planning rules for the downtown commercial districts, under Planning Code Section 148, so a pole between the towers on Montgomery and Market gets more wind allowed for than the map gives, and the spot gets picked with that in mind. The ground is the bigger cost. SoMa, Mission Bay, the Marina and most of the eastern waterfront are fill over bay mud — soft, deep and liable to liquefy — so the footing is engineered and reinforced rather than taken to a standard depth, and the anchorage detail is the part the plan checker reads. Salt comes in off the Gate and the bay on the same wind, so plated fittings do not last and we quote stainless. Work on a designated landmark or inside one of the city's historic districts goes through Planning before the Department of Building Inspection issues anything.

Most of the people who call us from San Francisco are downtown offices and hotels, hospitals and university buildings, city facilities, museums and cultural institutions, condominium and apartment associations, churches and waterfront restaurants.
