This 31 degree slope would be the result of getting a 5.5 foot sidewalk encroachment in the 22 foot sidewalk. (90% of all sidewalks in SF are 17 feet wide, or less.)
It would be, then, equal to the two most well known  "Steepest Streets" in SF...: Filbert at Leavenworth and  22nd Street at  Vicksburg on Potrero Hill.

If the City refuses, the resultant  35 degee slope will be 13 % steeper, and too steep to be safe, and usable.
  The result:  the occupant's cars will be parked on the street,  negating the reason for having garages.

It is surprising that the SF DPW ignores these points and just says "NO.  We simply have a total policy of not approving  an encroachment, if it would be the first one on that side of the block, no matter how wide the sidewalk.  < Across from 253 Parker is 252 Parker which DOES have such an encroachment, but the DPW  ignores that, for no understandable reason.)

Another view of a 35 degree slope, as DPW wants for 253 Parker Avenue, S.F.

Here is how to construct, on your computer a precise, 35 degree down grade, the complement to Angle B, below...which is, itself, 55 degrees..That 35 degree downslope is what DPW wants to be built on Parker Ave. Who would use it?

Thanks to the website,  "Mathinary"...for this calculation and image.

So, from B to C is the downslope that DPW is saying has to be the 35 degree slope into the garage.

Picture doing that daily, or, more daunting, picture backing up, to come out to the street.

Man, when one is in a "pout", due to the numbskulls at City Hall.....there is nothing better than a Cole Porter set of lyrics : To Wit:

ANYTHING GOES!

 Times have changed
And we've often rewound the clockSince the Puritans got a shockWhen they landed on Plymouth RockIf today, any shock they should try to standSteada' landing on Plymouth RockPlymouth Rock would land on them
In olden days a glimpse of stockingsWas looked on as something shockingNow heaven knowsAnything goes
Good authors too who once knew better wordsNow only use four-letter wordsWritting proseAnything Goes
The world has gone mad todayAnd goods bad todayAnd blacks white todayAnd days night todayWhen most guys todayThat women prize todayAre just silly jiggalo's
So though I'm not a great romanceI know that I'm bound to answerWhen you proposeAnything goes
The world has gone mad todayAnd goods bad todayAnd blacks white todayAnd days night todayWhen most guys todayThat women prize todayAre just silly jiggalo's
So though I'm not a great romanceI know that I'm bound to answerWhen you proposeAnything goesAnything goes

SF Dept. of Building Inspections: " You must have one garage per unit."....SF DPW, Bureau of Street Use and Mapping: " Your driveway must be 35 degrees downslope."....

Joseph Heller, author of "CATCH TWENTY TWO",  should have lived in San Francisco..

If so, he could have written a sequel :  "Catch  Thirty Five"...

A friend of mine is building three flats, and had to insert a three car garage, even though the City's
"DPW Dept, in effect, said  "Your Driveway slope has to be  35 degrees, not the 31 degrees that you would have, if we let your driveway encroach 5 feet into the 22 foot wide sidewalk...

Now my friend has to eat  the big expense of an appeal to the Permit Appeals Board, or live with a useless driveway..

31.5 degrees

31.5 degrees

37 degrees

41 degrees, Bernal Heights.

Darker is steeper.

37 degrees.

Halfway from 30 to 40 degrees is what DPW  demands.

I am a BIG non-fan of "Blogger", the  program by Google that is supposed to be the "cat's meow" of blogging....

Well, my cats meow a hell of a lot more plain spoken that Blogger manifests itself..

I can post up a new blog.  Easy...  but don't ask me to post a pdf file onto the blog... No way in hell is it evident that that can or CANNOT be done.

Am I alone in my frustration with BLOGGER?

ps:  Their pitiful "Help Section"  rots, too.
