253 Parker Ave, between Geary and Anza.

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".
