The regulations contained in this chapter are necessary for the protection and preservation of the public health, safety, and general welfare of the citizens of the City of Snohomish. The public school system which serves City residents is unable to provide the services required to meet the educational needs of the growing community. The purposes of this chapter are (1) to ensure that adequate school facilities are available to serve new growth and development; and (2) to require that new growth and development pay a proportionate share of the costs of new school facilities needed to serve new growth and development.
