Upon recommendation by the Director, the Common Council may, by resolution, impose sewer construction fees on individual properties in certain identified, unserved areas when properties in such area are benefitted by the installation of a sewer. All users in such service area shall pay an additional sewer construction fee prior to connecting to the sewer. This sewer construction fee shall be in addition to the other fees imposed by this chapter. The city may enter into agreements assigning the cost of installation of sewer and water mains to serve such service areas. The ordinance codified in this section implements authority granted in SDCL § 9-48-15.
