FINDING: Aquifer Recharge Area
|
|
Wording
|
| | |
Aquifer recharge areas in Jefferson County are characterized by porous geologic formations that allow percolation of the surface water into the soils and the underlying zone of saturation. Aquifers are geologic formations that contain sufficient saturated permeable material to yield significant quantities of water to wells and springs. Aquifers serve as the source of drinking water within most of the rural portions of Jefferson County.

FINDING: Susceptible Aquifer
|
|
Wording
|
| | |
Susceptible aquifer recharge areas are those with geologic and hydrologic conditions that promote rapid infiltration of recharge waters to groundwater aquifers. This includes any portion of Jefferson County with a DRASTIC index of greater than or equal to 180 points as determined using the U.S. Environmental Protection Agency DRASTIC methodology: Drastic: A Standardized System for Evaluating Ground Water Pollution Using Hydrogeologic Settings (EPA 600/23-87-035).

UNDERSTORY DAMAGE
|
|
Wording
|
| | |
All trees and understory lying outside of approved construction limits shall be retained during clearing for roadways and utilities. Understory damaged during approved clearing operations may, however, be pruned.

VEGETATION RETAINED
|
|
Wording
|
| | |
Vegetation retained on-site following completion of clearing for roadways, utilities and the like, may be cleared only if such clearing is absolutely necessary to complete the proposal (Note: This condition shall not be construed as allowing removal of native vegetation within a designated critical area or its associated buffer).

|
Wording
|
| | |
Surface drainage shall not be directed across the face of a marine bluff, landslide hazard or ravine. If drainage must be discharged from a bluff to adjacent waters, it shall be collected above the face of the bluff and discharged to the water by tight line drain and provided with an energy dissipating device at the shoreline. A shoreline permit is required to discharge water at the shoreline.

FOLLOW GEOTECH RECOMMENDATIONS
|
|
Wording
|
| | |
The applicant shall follow all of the recommendations rendered through the submitted Geotechnical Report. Said recommendations are as follows:
A.Native vegetation, particularly trees and low native brush on the slope should be disturbed as little as possible. If trees are thinned or limbed for view purposes should be limited to limbing for view corridors of Douglas Fir and Western Red Cedar. Any debris from thinning of the bluff slope itself should be removed from the slope.
B.Two additional discharge pipes shall be intalled to address stormwater. In addtion, the discharge should not take place over the bluff, and should be contained through a drywell or curtain drain.
