In a single volume, Standards ANSI/ASCE/EWRI 12-13, 13-13, and 14-13 establish the guidelines for design, installation, and operation and maintenance of urban subsurface drainage systems.
Standards ANSI/ASCE 12-92, ASCE 13-93, & ASCE 14-93 provide guidelines for design, installation, operation, and maintenance of urban subsurface drainage.
MOP 95 offers detailed information regarding the planning, design, construction, and operation and maintenance of urban subsurface drainage systems in urban areas.
This collection contains 91 papers presented at a specialty symposium on urban drainage modeling at the World Water and Environmental Resources Congress, held in Orlando, Florida, May 20-24, 2001.
The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
