Frequently Asked Questions (FAQ)

I would like to get some more information on the types and prices of computer programs that are listed in Section 6 of the Hydrology Manual.

Pricing and ordering are coordinated through the Public Works' Cashier's Office located at 900 South Fremont Avenue, Mezzanine Floor, Alhambra, CA, 91803. They are open Monday thru Thursday from 7 a.m. to 5 p.m. and the telephone number is 626-458-6397. They have a list of the programs still being used. Some of the programs referred to in the 1991 Hydrology Manual are no longer available. Information on the Modified Rational Method for hydrology studies can be found on Public Works' Intranet Site: under the heading Hydrology Manual Addendum.
