A.    Notwithstanding the provisions of this chapter, the city shall perpetually maintain the downtown streetscape district, including all landscaping, pursuant to standards established by the city engineer's office and approved by the board of public works and safety, except however, that any daily maintenance of sidewalks such as removal of snow, ice, other debris or natural obstructions, sweeping and weed removal, shall be performed by the landowner of any real estate adjacent to said sidewalk or right-of-way within the downtown streetscape district.

    B.    The minimum standards recommended by the office of the city engineer and approved by the board of public works and safety may not be decreased by said board of public works and safety without first providing written notice to all adjacent property owners within the streetscape district, notifying said property owners that the office of the city engineer proposes to change such standards. Such notice to the landowners shall provide at least ten days prior notice of any proposed changes to the minimum maintenance standards adopted by the board of public works and safety.
