However, the demands on most urban drainage systems are increasing because of rapid population growth and increasing areas of impermeable surfaces It should be used with other design manuals for floodplain management, total water cycle management, water sensitive urban design, and natural channel design and needs to be applied to local conditions.

STORM DRAINAGE DESIGN AND TECHNICAL CRITERIA Table of Contents Chapter Title Page 1.00 INTRODUCTION 1- 1 1.10 PURPOSE AND SCOPE 1- 1 1.20 CITY CODE PROVISIONS 1- 1 the Urban Drainage and Flood Control District's "Urban Storm Drainage Criteria Manual" (USDCM). The USDCM, including volumes 1 through 3 and any amendments issued by the Queensland Urban Drainage Manual (QUDM) QUDM assists engineers and stormwater designers in the planning, design and management of urban stormwater drainage systems. QUDM is designed to be used with other design manuals for floodplain management, total water cycle management, water sensitive urban design, and natural channel design. Road Drainage Manual The Road Drainage Manual, (RDM) 3 rd Edition, sets out a multi-disciplinary approach to the provision of drainage infrastructure. It is a guide to those involved in the planning, design, operation and maintenance of road drainage infrastructure for small, simple rural and urban catchments. It does not Step 1 - Determine Contributing Drainage Area Look at contour maps Consider structures and manmade changes Use your common sense and best engineering judgment Rational Method Step 2 - Compute Runoff Urban Design uses the rational method Q=CIA Q = maximum design rate of runoff, cfs C = runoff coefficient representing a ratio of runoff to rainfall The design of drainage facilities for all Illinois Tollway projects shall be performed in accordance with these criteria and applicable references cited herein. The following publications shall be used in the design of drainage facilities: • Illinois Tollway Design Section Engineer's Manual HEC 22 - Urban Drainage Design Manual (3rd edition) (September, 2009) HDS 4 - Introduction to Highway Hydraulics (June, 2008) HEC 14 - Hydraulic Design of Energy Dissipators for Culverts and Channels (3rd edition) (July, 2006) HEC 15 - Design of Roadside Channels with Flexible Linings (3rd edition) (September, 2005) Urban Hydrology for Small Watersheds Chapter 1 IntroductionIntroduction The conversion of rural land to urban land usually increases erosion and the discharge and volume of storm runoff in a watershed.
