recent_digs Read-only

Lists utility excavation permits on the blocks around one street address in New York City, Washington, DC, San Francisco, Los Angeles, San Diego, Seattle, Denver, and Chicago, newest first, at most 25 with the total found: the utility, the permit holder, what the work was, the issue date (or, where a city publishes none, the start date) and work window, whether digging is permitted today or scheduled to start later, the street and its distance. Use it for questions about who has been digging on a block, why a street is torn up, or how often it gets opened. Narrow with radius_m, since_year, utility or permitted_today. Permits that don't cut the street (opening a manhole, storing material) are left out. Answers are public-records evidence with a records-as-of date and end with the city's 811 notice.

addressstring, required

A street address with house number, in New York City, Washington, DC, San Francisco, Los Angeles, San Diego, Seattle, Denver, or Chicago. Include the city, e.g. "200 N Spring St, Los Angeles" or "33 Union Square West, Manhattan".

citystring

Which city the address is in, to search only that city and rule out a lookalike address elsewhere. One of "nyc" for New York City, "dc" for Washington, DC, "sf" for San Francisco, "la" for Los Angeles, "sd" for San Diego, "sea" for Seattle, "den" for Denver, "chi" for Chicago. The full name or a common short form works too, in any case: "Los Angeles", "NYC", "Brooklyn", "D.C.".

utilitystring

Only this kind of work: "electric" (electric), "gas" (gas), "telecom" (telecom), "water" (water), "sewer" (sewer), "steam" (steam), "capital" (city rebuild).

radius_minteger

How far around the address to look, in meters. Default 150, at most 400.

since_yearinteger

Only permits issued in this year or later. Where a city publishes no issue date (Los Angeles, Denver), the year the work starts counts.

permitted_todayboolean

true for only the permits whose work window includes today.

whats_under

Looks up what public records say is under the street in front of one street address in New York City, Washington, DC, San Francisco, Los Angeles, San Diego, Seattle, Denver, and Chicago. Returns each utility likely in the street (water, sewer, storm drain, gas, electric, telecom, steam) with its distance from the lot line, its expected depth and the code or standard behind it, and how the line was placed (the owner's published map, excavation permits on the block, or inferred) with a confidence label; the water service line's lead status where the city publishes it by address; the house sewer; digging permitted there today; the newest permits out front, each with its street, its distance from the address and its issue date (or its start date, marked scheduled when the work hasn't begun); and the nearest hydrant, catch basin and manhole. Use it for questions about what is under a street or sidewalk at an address, whether a dig might hit a line, or whether a service line is lead. Answers are public-records evidence with a records-as-of date, not a survey or a utility locate, and end with the city's 811 notice. An address outside these cities, or with no exact match, returns an error saying what was found instead.
