(2) Upon any other lot or land no greater than 18 inches.
(B) The following areas and types of vegetation are exempted from this provision if managed in a manner so as not to become infested with weeds or to create a stagnant, foul-smelling condition:

(2) Native vegetation found in natural areas which are part of public open space, parks and nature centers;
(3) Areas of any occupied lot or parcel of land having wetland-type vegetation because of neighborhood drainage patterns, where the drainage pattern is evident on contour maps and from field observation, and the vegetation is confined to a single lot, separated from adjacent lots and managed so as not to be a nuisance;
(4) An area where the land and vegetation appear not to have been graded, landscaped, mowed or otherwise disturbed by human or mechanical means at any time. The Weed Inspector shall use reasonable judgment in determining what constitutes this type of area based on the present appearance of the area and research as to the history of the area, if such information is available;
(5) An area of at least five acres used by an educational institution or public agency for prairie land restoration, if the prior vegetation is eliminated and the prairie vegetation is planted through transplanting or seed. The area shall be cut at least once per year to a height of no more than 18 inches if weeds cover more than 25% of the area. If such mowing is necessary and the area is likely to be seen by the public, a sign shall be posted advising that a meadow or prairie is being established. The size of the sign shall be one square foot and it shall be no higher than three feet;
(6) Natural wooded lots; and
(7) Native plant landscape areas; provided that:

2. The native plants abut a neighboring native plant landscape area;
(c) The native plant landscape area is cut at least once annually between April 15 and July 15 to a height no greater than ten inches;
(d) Turfgrass is eliminated and the native plants, trees and shrubs are planted through transplanting or seed by human or mechanical means. Soil erosion should be controlled while the ground is bare of plant growth that is sufficient to inhibit erosion and is the sole responsibility of the owner or occupant; and
(e) Written authorization from the City Administrator or his or her designee is obtained for work within conservation or scenic easement areas, including planting, mowing or cutting.
(C) No such person shall cause, permit or allow poison ivy, ragweed or other poisonous plants or plants detrimental to health, to grow on any such lot or any such land in such manner that any part of said weeds or plants shall extend upon, overhang or border any public place or in such manner that said weeds or plants are allowed to seed or to emit pollen or other poisonous particles into the atmosphere in a manner such that said particles are carried through the air into any public places.
