2. Walking Distance

Distance measured as the most direct path of travel for a pedestrian.

a. Measurement

Walking distance is measured horizontally along the most direct route of travel on the ground in the following manner:

i. Starting at the nearest street-facing entrance accessible to the majority of tenants or residents on the subject lot;
- ii. In a straight line to the nearest public sidewalk, walkway, street, or road;

iii. Along a public sidewalk, walkway, street, or road; and

iv. In a straight line ending at the nearest pedestrian access point to the destination use.

1200.B. Enclosure

The measurement of how closed off an occupiable space is to its surroundings.

1. Standards

a. Enclosed

A space is considered to be enclosed when the perimeter of the space has an enclosure of at least 65%.

b. Unenclosed

A space is considered to be unenclosed when the perimeter of the space has an enclosure of less than 65%.

c. Perimeter Plane

An imaginary vertical plane along the perimeter of a space used to measure the enclosure of a space. A perimeter plane must be projected for a height of 8 feet measured from the floor or ground surface of the space.

d. Solid Area

The portions of the perimeter planes that have a permanent structure or component obstructing the space from its surroundings. For the purpose of measuring the enclosure of a space, portions of the perimeter plane are considered solid area where a permanent structure or component is

located within 5 feet of the perimeter plane, measured perpendicular to the perimeter plane and away from the subject space.

e. Non-Solid Area

The portions of the perimeter planes along the perimeter of a space that have no permanent structure or component obstructing the space from its surroundings. For the purpose of measuring the enclosure of a space, portions of the perimeter plane are considered non-solid area where no permanent structure or component is located within 5 feet of the perimeter plane, measured perpendicular to the perimeter plane and away from the subject space.

f. Solid Perimeter

The length of a perimeter of a space that consists of solid area for the entire height of the perimeter plane.

2. Measurement

a. Enclosure is measured as a percentage, calculated by dividing the cumulative length of the perimeter of a space that is solid perimeter by the total perimeter of the space.
b. For spaces with perimeter planes that do not contain a mixture of solid area and non-solid area for the full height of the perimeter plane, enclosure must be calculated as the length of the solid portion of the perimeter divided by the total perimeter.
