Improved sites with nonconforming development standards, such as paving, landscaping, buffering, number of parking spaces or other site development standards as specifically required for that zoning district or use, may continue to exist, subject to the following:
(a) Compliance. To the extent practical, such nonconforming sites shall be brought into compliance with all applicable development standards as part of the site plan review process as required by Chapter 1278 when building additions or other site improvements requiring a site plan review are proposed.
(b) Compliance Agreements. Where the Planning Commission determines that it is clearly not practical or not in the public interest to bring a nonconforming site into total compliance with all applicable development standards, the Commission may secure agreements to provide reasonable, lesser improvements which will protect the interests of the both the applicant and neighboring property owners. All new site improvements shall comply with current development standards.
