"Monitoring" means the collection and analysis of data by various methods for the purposes of understanding and documenting changes in natural systems and features,and including gathering baseline data,evaluating the impacts of development proposals on the biological,hydrologic and geologic elements of such systems,and assessing the performance of required mitigation measures. "Native vegetation"means vegetation on a site or plant species which are indigenous to the area in question;or if the site has been cleared,species of a size and type that were on the site on the effective date of this title or reasonably could have been expected to have been found on the site at the time it was cleared.

"Ordinary high watermark" means the mark that will be found by examining the channel bed and banks of a stream, lake or pond and ascertaining where the presence and action of waters are so common and usual,and so long maintained in all years of normal rainfall,as to mark upon the soil a character distinct from that of the abutting upland in respect to vegetation. In any area where the ordinary high water mark cannot be found,the line of mean high water shall substitute. In braided channels and alluvial fans,the ordinary high water mark or substitute shall be measured so as to include the entire stream feature. "Plant associations of infrequent occurrence"means one or more plant species on a landform type which, because of the rarity of the habitat or the species involved or both,or for other botanical or environmental reasons,do not occur frequently in Everett or Snohomish County.

"Riparian corridor" means a perennial,intermittent,ephemeral stream or swale including its channel bottom, lower and upper banks,and area beyond the top of the upper bank which influences the stream through shading and organic matter input,and is influenced by the presence of water,particularly in regard to plant composition. The riparian corridor is the transitional area between aquatic and upland ecosystems and does not necessarily include the entire floodplain of a stream. "Salmonid" means a member of the fish family Salmonidae. In the city these include chinook,coho,chum,sockeye and pink salmon;cutthroat, brook,brown, rainbow and steelhead trout;and Dolly Varden, kokanee and char. "Seismic hazard areas"means those areas of the city subject to severe risk of earthquake damage as a result of seismically induced ground shaking,settlement,or soil liquefaction.These conditions occur in areas underlain by cohesionless soils of low density sometimes in association with a shallow ground water table. "Significant biological areas"means the following areas of the city: 1. Plant associations of infrequent occurrence; Ch.19.04 Definitions 26 City Council Action(11/04/2020)
