Manuscript volumes of minutes, 1858-1870 (ABG300) and one register of certificates, 1861-1862 (ABG650).

The minute entries are signed by the secretary of the committee and include listings of the items of business heard at each committee meeting, along with the action taken by the committee. While the entries do not give much detail on the projects under discussion, the minutes as a whole give an overview of the process by which the city's infrastructure was maintained during the period. A sample entry from the May 26, 1859 meeting reads "#6, communication from Mssrs. Surgi and Passau with a plan for erecting a fountain in Lafayette Square -- lay over."

The register lists certificates issued by the Surveyor and the Street Commissioner for services performed by contractors, apparently indicating acceptance of the work by the city. Each entry includes the certificate number, date, name of the certifying officer, name of the contractor, a statement of the work performed, a reference to the resolution or ordinance authorizing the work, the period of time for which the payment is being made, the basis for payment, and the amount to be paid. This register appears to have been maintained jointly by the chairmen of the two Committees on Streets and Landings. The remainder of this volume was used to record the minutes of the Bureau of Streets and Landings from June 2, 1862 through June 30, 1863.

The register of certificates and volume 1 of the meeting minutes are available on microfilm; remaining materials are unfilmed and only available in original format.
