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 use of joist hangers provides a quick, economic and reliable method for forming timber-to-timber joints and for supporting timbers on masonry or steel beams. Although their installation is less dependent on traditional trade skills, care must be taken when specifying and fitting joist hangers. This guide is for building designers, contractors and site supervisors. It shows how to use hangers to support timber joists in new construction work, and stresses the importance of correct specification and installation to ensure good performance. This guide replaces BRE Defect Action Sheets 57 and 58, which have been withdrawn.
