Getting Around in Palmdale

The Major Street Network

The major street network in Palmdale follows a grid pattern, with street names and numbers to assist in providing convenient location of residences, businesses, and other properties. In addition, the layout allows easy calculation of distances. The convenience of the system also assists in emergency response, deliveries, and other activities.

Major city streets are referred to as arterial streets. These roadways provide the capacity for longer trips within and through the city.

Based on anticipated traffic volumes as the city grows, arterials are planned to have medians for left-turn movements and multiple through lanes. Secondary arterial roadways are planned to have two through lanes in each direction. Major arterial roadways are planned with three through lanes in each direction, and regional arterial roadways with four through lanes in each direction.

Major arterial roadways are generally spaced one mile apart, with secondary arterial roadways located between the major arterials at a spacing of one-half mile from the major arterials. Regional arterials are identified in the City’s General Plan as needed for future capacity.

East-West Arterials

Arterials oriented along east-west alignments are generally designated with letters, such as Avenue P, Avenue Q, and Avenue R. Avenue A is located at the northern boundary of Los Angeles County. Each letter designation indicates a distance of one mile. Each mile is generally divided into 16 sections for the potential spacing of other street designations. Therefore, secondary arterials midway between major arterials have a letter designation with the number 8, as in Avenue P-8. Palmdale Boulevard is generally equivalent to Avenue Q-8.

North-South Arterials

For arterials running north and south, the major arterials at one mile spacings are multiples of 10. For example, 10th Street East to 20th Street East is approximately one mile. Secondary arterials are at one-half mile spacings between major arterials, and generally end in a 5, such as 15th Street East. Division Street is the center street between east and west. Therefore, 10th Street West is one mile west of Division Street and 10th Street East is one mile east of Division Street.

Odd and Even Address Numbers

Odd numbered street addresses are generally found on the north and west sides of the street. Even numbered street addresses are generally found on the south and east sides of the street.

Block Numbers

For east-west streets, block numbers increase by 1000 per mile each direction from Division Street. For example, the east 1000 block of Avenue P begins at 10th Street East. It is essential to designate east or west when referring to east-west street addresses. For example, 1000 East Avenue P is 2 miles from 1000 West Avenue P.

Block numbers along the north-south arterials are in increments of 800 per mile. The following table summarizes the block numbers along north-south roadways at intersections with the east-west arterials. Although the block numbers are technically all north (such as 38800 North 10th Street West), it is typically not necessary to indicate the north designation.
