(a) Whenever necessary to make an inspection to enforce any of the provisions of this chapter, or whenever an authorized enforcement official has reasonable cause to believe that there exists in any building or upon any premises any condition which constitutes a violation of the provisions of this chapter, the official may enter such building or premises at all reasonable times to inspect the same or perform or have performed by others any duty imposed upon the official by this chapter; provided that: (1) if such building or premises be occupied, he or she shall first present proper credentials and request entry; and (2) if such building or premises be unoccupied, he or she shall first make a reasonable effort to locate the owner or other persons having charge or control of the building or premises and request entry.

(b) Any such request for entry shall state that the property owner or occupant has the right to refuse entry and that in the event such entry is refused, inspection may be made only upon issuance of a search warrant by a duly authorized magistrate. In the event the owner and/or occupant refuses entry after such request has been made, the official is hereby empowered to seek assistance from any court of competent jurisdiction in obtaining such entry.

(c) Routine or area inspections shall be based upon such reasonable selection processes as may be deemed necessary to carry out the objectives of this ordinance, including but not limited to random sampling and/or sampling in areas with evidence of stormwater contamination, illicit discharges, discharge of non-stormwater to the stormwater system, inspection of stormwater treatment facilities, or similar factors.

(d) The City shall have the right to establish on any property such devices as are necessary to conduct sampling or metering operations. During all inspections as provided herein, the official may take any samples deemed necessary to aid in the pursuit of the inquiry or in the recordation of the activities on-site.
