9.56.010 Purpose.

It is the purpose of this Chapter to ensure that both commercial and noncommercial growers of plants within the Brassicaceae family in Skagit County can reasonably coexist, by creating a mechanism to timely and reasonably provide notice and opportunity to cure as well as a mechanism to seek rapid judicial relief in the event that inter-landowner communication does not resolve the conflict arising from proximate Brassica crops. This Chapter is intended to supplement, and shall not alter, limit, or supersede, any other statutory and/or common law rights and/or causes of action for the abatement of public and/or private nuisances. (Ord. O20210002 (Exh. 1); Ord. O20190004 (Exh. 1))

9.56.040 Abatement remedy.

A party aggrieved by a violation of SCC 9.56.030 may seek redress and abatement according to the following remedy, and a flowering Brassica shall not be deemed a nuisance flowering Brassica unless the following notice and opportunity to cure provisions have been satisfied, which provisions shall be strictly interpreted:

(1) Notice. No flowering Brassica on a property shall be deemed a nuisance for the purpose of this Section unless notice has been furnished by an aggrieved party to the landowner(s) and tenant(s) in possession of the property to be charged with a nuisance under this section. The aggrieved party shall be solely responsible for correctly identifying the legal owner(s) and tenant(s) in possession of the property to be charged with a nuisance under this section. Notice furnished by the aggrieved party shall be deemed sufficient if accompanied by a declaration of service under penalty of perjury stating that the notice was delivered in person, posted on the door of the main residence at the property to be charged with nuisance, or placed in the U.S. mail addressed to the occupant of the property to be charged.

(2) Opportunity to Cure.

(a) Upon detection of a nuisance flowering Brassica, an aggrieved party seeking abatement must offer the landowner or tenant maintaining the nuisance flowering Brassica the estimated fair market value of the nuisance flowering Brassica in exchange for abatement (removal) of the nuisance flowering Brassica. The aggrieved party shall be responsible for determining and establishing the estimated fair market value of the nuisance flowering Brassica; provided, that landowner(s) and/or tenant(s) maintaining the nuisance flowering Brassica are not obligated to agree with or accept the estimated fair market value of the nuisance flowering Brassica as offered by the aggrieved party.

(b) If the offer set forth in Subsection (2)(a) of this Section is not accepted within 24 hours and the nuisance flowering Brassica abated, the aggrieved party may bring suit in the name of the aggrieved party to enjoin and abate the nuisance. (Ord. O20210002 (Exh. 1); Ord. O20190004 (Exh. 1))
