This book presents a comprehensive method by which to determine the proportionate share of the costs and revenues generated by the development of new water, wastewater, and stormwater facilities. It presents a rational, legally defensible approach to assessing charges based on the use of new and existing facilities to support new system development. Written by a consultant who has helped hundreds of communities deal with how to pay for growth, the book is designed for all communities presently engaged in calculating and administering charges for new development, as well as those planning for future growth.
