undesirable or impracticable, the above conditions may be modified.

U-shaped courts and loop streets are strongly suggested as alternatives
to strip development.

from each other at any one point by more than 10°, shall be connected
with a curve, the radius of which for the center line of the street
shall not be less than 400 feet on major streets, 200 feet on collector
streets and 100 feet on minor streets.
G. Gradient. Grades of all streets shall conform in general to the terrain
and shall not be less than 1/2% nor more than 6% for major or collector
streets or 10% for minor streets in residential zones, but in no case
more than 3% within 50 feet of any intersection.
H. Naming.
(1) Street names shall not duplicate or be similar to existing street
names in the Town of Porter.
(2) Streets have full names and not numbers or letters.

the established buffer may impact the biodiversity and environmental
quality of the wetland, mitigation measures may be required as determined
and approved by the municipality and for regulating authorities.
