LOGGING ROADS AND PROTECTION OF WATER QUALITY

This state-of-the-art report on the protection of water quality in planning, designing, constructing, reconstructing, using and maintaining logging roads, is intended as an aid for dealing with nonpoint source pollution control. The text, which is designed to assist state, federal and local agencies, industry and the general public in the identification of potential hazards to water quality and the selection of procedures suitable for preventing or correcting water pollution problems, reviews a range of logging road design standards. The roads considered vary from low-speed narrow, unsurfaced roads to moderately high speed, rocked or paved roads. Details are given of forest lands (in the Environmental Protection Agency Region X), their physiography and soils, geology, climate and forest statistics such as ownership, logging road activity and cost. General water quality problems and in surveillance operations are outlined. The importance is logging road sediment. Monitoring approaches and parameters program for a proposed road. The general design approach must be that of according individual treatment to the individual circumstances of the sites. Features responsible for drainage-associated mass failures are listed. Minimizing surface erosion begins with treatment or design of slope protection, and continues with attention to ditch size, lining, culvert intakes, culvert integrity and culvert outlets. Vegetative or other forms of permanent cover are essential. It is important to sequence the construction in a manner that affords the least exposure to storm damage during construction. The features of a successful maintenance program are discussed. The inclusion of design criteria for sediment control may increase capital outlay but it does not necessarily increase total annual cost over road life.
