t.e.d:Oh yeah, If anyone can recommend an Android ap that will do what it takes to map these, let me know and I'll start collecting data.Not sure that smart phone data are accurate enough for this: My location is 115' above sea level, and my iPhone altimeter shows an elevation of 30' with an accuracy of +/250' = useless! My GPS' vertical accuracy isn't too hot, either, but is typically <10' 95% of the time when with a clear view of the sky.
billd:GPS altimeters are pretty close to useless; unless you are fine with hundreds of feet of inaccuracy.My GPS (Legend HCX) does not have a barometric altimeter so I cannot comment on the accuracy of such data; instead the HCX uses satellite data to estimate elevation. The rule of thumb that I have read (but cannot verify) is that vertical accuracy from consumer grade GPS units is approx. 1.5 times that of the state horizontal accuracy, routinely reported in the sub-10' magnitude on my GPS. Based om that, I would say that achieving an elevation accuracy of well under 20' under good reception conditions is realistic.
James P Griffin:I nominate Upas between Florida and Park (although the leveling off just before Park might lower its average slope)
James P Griffin:Also, the streets leading from Rosecrans down to the submarine base are reputed to be quite steep.

Also the very appropriately named Hill St. from O.B. up to Catalina St. Puff puff pant pant.
PacMUle:what about Texas st? !I think Texas is one of those long and steep hills, too - probably both shorter and less steep than Via Capri, but certainly a deserving nomination!
Njord Noatun:
As far as being both steep and long at the same time, Via Capri is certainly up there! (So is Torrey Pines inside).
Serge:Great thread.Is that starting at the intersection with Hidden Valley Rd? I wonder what the grade is right at that right hand curve.Yes. The "rules" of the listing is that the hill has to be at least one block long, and the section of hill at Hidden Valley is less than a block, IIRC. But it is really step right at the intersection!
Serge:Pacifica is a killer.Yes! And Pacifica starts well below Loring, but flattens out, and even drops, before it gets to the next intersection at Romney, so the real hilly section of Pacifica is steeper and possibly longer than the official measurement above.
batmick:Has Del Mar Heights been mentioned yet, from the 101 to the top of the hill?That looks pretty steep - but I limited this post to the City of San Diego, in order to concentrate the efforts to get something going in SD first.
Praxis:the steepest that comes to mind is north from Illion Street and Gardena Avenue. I wonder where Bachman is in the running?Where on Gardena is this, Praxis?
Njord Noatun: Where on Gardena is this, Praxis?
William.:What is the hill I see going north on 805 just past the cross over of the 8?

Ah, but Del Mar Heights is in the City of San Diego. Del Mar didn't want it. They didn't want North City West either.
I like the name Gardena. It means "Spear Danes" in Old English.
bëany:Nomination: How about Ash where Home Ave ends? Pointless hill that doesn't go anywhere and I found that out the hard way. I would like to know whether it is legal ride that stretch of 94 from where Home Ave ends to and exit out at Broadway.
wpstoll:It would be safe and wonderful to be able to ride freeway shoulders between on/off ramps, but the only place CalTrans will allow it in San Diego County is I-5 between Sorrento Valley and Genesee, I-52 between Santo Rd. and Mast Blvd., and on I-8 in places where Hwy 80 was overlayed by the freeway.
billd:Last I heard, it was still allowed on I-15 between West Bernardo/Pomerado and Via Rancho Parkway (across Lake Hodges) even though they have a pedestrian/bike bridge. Not sure if it's still true.
