Due to the uniqueness of the road infrastructure of the City of Unalaska, addressing will be discussed in parts.
(A) Downtown Unalaska. Numbers shall rise from the Origin (Broadway Avenue and 5th Street). Numbering from the Origin shall begin with zero in each direction.
(B) Other streets, rights-of-way. A street shall rise in numbers from the beginning of that street that is closest in possible travelled distance to the Origin. For example, a loop shall be numbered from the ingress closest to the Origin.
(C) Numbering increments. For the purposes of the City of Unalaska's unique road system, a numbering system based on miles and fractions of miles shall be used.
Fractional Miles | Feet | Numbering Increment |
Fractional Miles | Feet | Numbering Increment |
1/128 | 41 | 8 |
1/80 | 66 | 12 |
1/64 | 82 | 16 |
1/40 | 132 | 25 |
1/32 | 165 | 31 |
1/20 | 264 | 50 |
1/16 | 330 | 62 |
1/10 | 528 | 100 |
1/8 | 660 | 125 |
1/5 | 1056 | 200 |
1/4 | 1320 | 250 |
1/2 | 2640 | 500 |
1 | 5280 | 1000 |
1 1/28 | 5321 | 1008 |
1 1/20 | 5544 | 1050 |
1-1/2 | 7920 | 1500 |
Example: Down Town Unalaska - Broadway running in a predominantly western direction from the origin shall be addressed 100 W. Broadway Avenue at 1/10 mile on the Southerly side of that street (in this case the left side from the Origin).
(D) Individual address. Individual businesses and single family dwellings shall each have a separate number. Duplexes will receive two numbers. Apartment buildings with a common entrance will have one number followed by an apartment designation (A, B, C or 1, 2, 3 etc.).
(E) Multi-family dwelling units and office complexes. Each shall have a street number with individual apartments/suites/offices designated by either alphabetical suffix (i.e. 101A, 101B, etc.) or numerical designation (i.e. 101 4th Ave. Apt. 200).
(F) Multiple entrances. Large buildings with multiple entrances including apartments, shall have a number for each entrance that faces a road or street.
(G) Corner parcels. Corner lots will be assigned as number depending on which direction the main entrance faces.
