A. 
13.01.110.A.
“Adjacent.”
Immediately adjoining (in contact with the boundary of the influence area) or within a distance that is less than that needed to separate activates from critical areas to ensure protection of the functions and values of the critical areas. Adjacent shall mean any activity or development located:
1. 
On a site immediately adjoining a critical area;
2. 
A distance equal to or less than the required critical area buffer width;
3. 
A distance equal to or less than one-half mile (2,640 feet) from a bald eagle nest;
4. 
A distance equal to or less than three hundred (300) feet upland from a stream, wetland, or water body;
5.

“Anadromous fish.”
Fish that spawn and rear in freshwater and mature in the marine environment. While Pacific salmon die after their first spawning, adult char (bull trout) can live for many years, moving in and out of saltwater and spawning each year. The life history of Pacific salmon and char contains critical periods of time when these fish are more susceptible to environmental and physical damage than at other times. The life history of salmon, for example, contains the following states; upstream migration of adults, spawning, inter-gravel incubation, rearing, smoltification (the time period needed for juveniles to adjust their body functions to live in the marine environment), downstream migration, and ocean rearing to adults.
“Aquifer.”
A geologic formation, group of formations, or part of a formation that is capable of yielding a significant amount of water to a well or spring.
“Aquifer critical recharging areas.”
Areas that, due to the presence of certain soils, geology, and surface water act to recharge groundwater by percolation.

They also include areas with rare or uncommon plant species and associations designated by the City or identified by Federal and State agencies such as the Department of Natural Resources Heritage Program. They are not associated with a specific priority species and their overall habitat function may be limited due to their location in a highly urbanized area; however, they are diverse relative to other areas in the City and support common urban species.

“Clearing.”
The destruction or removal of logs, scrub-shrubs, stumps, trees or any vegetative material by burning, chemical, mechanical or other means.
“Compensatory mitigation.”
Replacing project-induced loses or impacts to a critical area, and includes, but is not limited to, the following:

Enhancement is undertaken for specified purposes such as water quality improvement, flood water retention or wildlife habitat. Activities typically consist of planting vegetation, controlling nonnative or invasive species, modifying site elevations or the proportion of open water to influence hydro-periods, or some combination of these.
