City Engineers have established multiple surveyed benchmarks throughout the City. The benchmarks indicate elevation at a described location, and help staff and others establish streets, grades, sewers and drains.
You can search for and locate benchmarks on the Web site:
Within several established benchmark boundaries.
In any part of the City, with tools you click and apply to the benchmark map. See a related Help topic, Use Benchmark Tools.
1 On
the City Home page, in the City Quick Links section, click PW Engineering:
2 On the PW Engineering page, in the Navigation - Current Level section, click Benchmarks.
3 With
the PW Engineering Benchmarks
page displayed . . .
. . . to find one or more benchmarks, follow the
instructions in "Address search" (just below) or "Benchmark
boundaries."
On the Search tab, type a full or partial building number, street name or address, and click Submit.
Search Results tab displays with one or more addresses, or with a message indicating the search could not match your entry.
Important The more complete the address, the more the program narrows your search and the more likely it will list the address. Read more about this
When you search with a partial address, the search can return only up to 50 addresses at one time, based on the partial entry. The address you are looking for may not appear in the list of 50 returned addresses.
Wild card in search. Including a "wild card" (the percent symbol % ) in your search string gives a partial address search the potential of locating the address you want. The search program replaces the percent symbol with characters it finds in addresses.
View examples of a wild card and other search notes
For
example, if you're searching for an address in the 1300 block of Jefferson,
typing Jefferson returns just
50 addresses of all the possible addresses that include "Jefferson"
in the address. None of these first 50 addresses listed are in the 1300
block.
A
wild card allows you to narrow the search: 13% Jefferson displays
all addresses in the 1300 block:
The program looks for characters anywhere in the address. In a search for Valhalla Street, val finds Avalon Street; Valh finds Valhalla.
Search
looks for consecutive numbers,
which can be at the beginning, end or in the middle of the address. Search
with 12
returns this list:
Include directions. W 10th returns a different list of addresses than E 10th .
You can use more than one wild card in a search, anywhere in the address string.
On the Search Results tab, click Select at the end of an address line.
The map displays the area near the
address, with a star indicating the address and triangles indicating nearby
benchmarks.

Notes
Currently (April, 2006) not all boundary areas immediately display benchmarks. If that's the case, use a map tool (Zoom In or Box Selection) to further define your search area. Read more about tools in the Use Benchmark Tools topic.
When you select a boundary, the map displays the boundary area in a color different from what the Legend indicates.
