Defining public services as the basic community/regional services which are provided to residents through tax receipts and service charges, this publication identifies variables for each service group and presents them in the form of questions that communities should find useful when analyzing impacts of growth. After listing questions dealing with the two key variables--the number of new people and where they will be located--the guide propounds questions about education, fire and police protection, roads, and streets, health care, sewage collection and treatment, water, and solid waste collection and disposal. Sample questions include: How many students will be added to the local school system? Will new school buildings be needed, and when? What is the estimated number of new households in the fire service area and where are they located? Will new residents be a higher crime risk group? How many miles of new roads will be needed and at what cost? What age group dominates the new population? Will the incidence of illness be higher than now? What is the estimated number of new sewage connections? Is expansion of existing water lines necessary? How much additional refuse will be generated by the new population? Suggested information sources conclude the document. (BRR)
