LUC CREDIT 2: SLOPES
1 POINT
INTENT
To minimize disturbance, erosion of steep slopes, and changes in grade;
reduce habitat impacts, cleared area and cut and fill volume; and
diminish fire and earthquake danger.
REQUIREMENTS
Build on sites that have no slopes greater than
25%. (1
point)
OR
On previously developed sites with slopes greater than 25%.
•
Treat any fractions of the site that have not
been previously developed by complying with the requirements for sites
that are not previously developed as set forth below; (1 point)
Reduce disturbance and erosion by:
•
Green design and construction to reduce cut and fill volume
• Using mechanically stabilized
earth, soil
nails, or other retention systems to reduce cut and fill volume of
roads, parking lots, and graded areas, as well as resist erosion
• Using best available control
technology for erosion control
• Restoring slopes with native
or adapted vegetation
Apply creative evaluation and technology by:
• Geological analysis to
facilitate development
on slope segments that are less vulnerable to erosion and slope
instability, and are capable of standing at steeper angles (e.g.,
resistant bedrock)
• In rare instances, tunneling
• Biological evaluation to
reduce habitat impact
(e.g., some slope segments may have vegetation that is less attractive
to wildlife)
• No flat topping of hillsides.
Note: Some codes and guidelines suggest setbacks from top and toe of
steep slopes. It is typical to avoid construction within 50 feet of the
top of the slope, and 75 feet from the toe of the slope.
These
values may be revised by geotechnical evaluation of slope stability.
