TABLE 3. VEHICULAR LANE DIMENSIONS

This table assigns lane widths to transect zones. The target speed is the determinant for each of these sections. The most typical assemblies are shown in Table 4.

TABLE 4. VEHICULAR LANE/PARKING ASSEMBLIES

The projected target speeds determine the dimensions of the vehicular lanes and turning radii assembled for thoroughfares.

TABLE 5. PUBLIC FRONTAGES—GENERAL

The public frontage is the area between the private lot line and the edge of the vehicular lanes. Dimensions are given in Table 6.

a. (HW) For Highway: This Frontage has open Swales drained by percolation, Bicycle Trails and no parking. The landscaping consists of the natural condition or multiple species arrayed in naturalistic clusters. Buildings are buffered by distance or berms.
b. (RD) For Road: This Frontage has open Swales drained by percolation and a walking Path or Bicycle Trail along one or both sides and Yield parking. The landscaping consists of multiple species arrayed in naturalistic clusters.
c. (ST) For Street: This Frontage has raised Curbs drained by inlets and Sidewalks separated from the vehicular lanes by individual or continuous Planters, with parking on one or both sides. The landscaping consists of street trees of a single or alternating species aligned in a regularly spaced Allee, with the exception that Streets with a right-of-way (R.O.W.) width of 40 feet or less are exempt from tree requirements.
d. (DR) For Drive: This Frontage has raised Curbs drained by inlets and a wide Sidewalk or paved Path along one side, related to a Greenway or waterfront. It is separated from the vehicular lanes by individual or continuous Planters. The landscaping consists of street trees of a single or alternating species aligned in a regularly spaced Allee.
e. (AV) For Avenue: This Frontage has raised Curbs drained by inlets and wide Sidewalks separated from the vehicular lanes by a narrow continuous Planter with parking on both sides. The landscaping consists of a single tree species aligned in a regularly spaced Allee.
f. (CS) (AV) For Commercial Street or Avenue: This Frontage has raised Curbs drained by inlets and very wide Sidewalks along both sides separated from the vehicular lanes by separate tree wells with grates and parking on both sides. The landscaping consists of a single tree species aligned with regular spacing where possible, but clears the storefront entrances.
g. (BV) For Boulevard: This Frontage has Slip Roads on both sides. It consists of raised Curbs drained by inlets and Sidewalks along both sides, separated from the vehicular lanes by Planters. The landscaping consists of double rows of a single tree species aligned in a regularly spaced Allee.

 

TABLE 6. PUBLIC FRONTAGES—SPECIFIC

This table assembles prescriptions and dimensions for the public frontage elements—curbs, walkways and planters—relative to specific thoroughfare types within transect zones. Table 6.a. assembles all of the elements for the various street types.

TABLE 7. PUBLIC PLANTING

This table shows six common types of tree shapes and their appropriateness for thoroughfare type and transect zone.

TABLE 8. PUBLIC LIGHTING

Lighting varies in brightness and also in the character of the fixture according to the transect.
