If S.F. grants this new building the requested "sidewalk encroachment, 5 feet, the upslope will be
32 degrees..... 10% steeper than Duncan Street, as seen below. Without the Encroachment:
37 Degrees.
These two pics show Duncan Street, in Noe Valley, between Diamond and Douglass Streets, a 28 degree slope....
If S.F. does not grant a "5 foot sidewalk easement to the new "'three unit condo building at 253 Parker, the resultant up-slope driveway will be a 37 Degree grade... 37 Degrees! ..making the garage only accessible to "mountain goats".
