But the most determined opposition to the installation of the trolley system came from improvement clubs, whose purpose was to promote the best development of San Francisco. Prominent among these organizations were the Improvement and Adornment Association,[33] the Sutter Street Improvement Club[34] and the Pacific Avenue Improvement Club. The membership of these organizations consisted of some of the largest owners of San Francisco properties. The leaders were comparatively young men, natives of San Francisco, whose interests were inseparably wrapped up in the community, and who aimed to promote the best possible development of the city of their birth and fortunes. Prominent in this group were Rudolph Spreckels[35] and James D. Phelan,[36] rated among the heaviest property-owners of San Francisco. These men were ready to join with the United Railroads in any plan which proposed the highest development of the street-car service.[37] On the other hand, they were prepared to oppose any attempt to exploit the service to the detriment of San Francisco.[38] A conference of the directors of the Improvement and Adornment Association with officials of the United Railroads was finally arranged.[39] The meetings were held in March, 1906, less than a month before the great fire. There were, before the attempted adjustment was abandoned, several sessions. The citizens urged Patrick Calhoun, president of the United Railroads, to give up his trolley design for Market and Sutter streets. As a compromise, he substantially agreed to build the underground conduit as far as Powell on Sutter, and as far as Valencia on Market, picking up the trolley on Valencia, McAllister, Hayes and Haight streets. The Adornment Committee directors wanted the conduit system on Sutter street extended as far as possible, and held out for Van Ness avenue. Calhoun would not consent to install the conduit beyond Powell. In the midst of this deadlock, the San Francisco Chronicle published what purported to be reports of the several conferences. Up to that time there had been no publication of the meetings. Following the Chronicle publication, Calhoun, in a letter to members of the Adornment Association, declared the information contained in the Chronicle article to be inaccurate,[40] and offered to let the people decide whether they wanted a conduit system on Market street to Valencia, and on Sutter street to Powell, or a uniform all-trolley system throughout the city. Mr. Calhoun's suggestion seemed reasonable until he stated in an interview that by the people he meant the Board of Supervisors. He was asked how he proposed to ascertain the wishes of the people. "I should suggest," he is reported as replying, "that the matter be referred to the decision of the Board of Supervisors. The Board of Supervisors is a public body selected by the people, and represents the ideas and wishes of the people of the city."
