Frequently Asked Questions (FAQ)

Question:
Where can I obtain the PDF files for the LA County Hydrology Design Manual appendices?

ANSWER:
The Hydrology Manual consists of more than 120 Acrobat (.pdf) files. Each appendix and its components, if any, are separate files. In order to download a file, such as an appendix or its component, you have to open it first. Download the file by selecting the diskette icon in the acrobat window and "save a copy" of the selected file.

The entire manual is also available on CD-ROM and can be purchased from our cashiers office (about $39). Our cashiers office is located on the mezzanine (M) level of our Headquarters at 900 South Fremont Avenue, Alhambra, CA 91803, Tel. No. 626-458-6397. It is open Monday through Thursday.
