Street Typologies

Carmel has a renowned system of streets and street design standards that have made possible not only the accommodation of growth but the safe use of streets by pedestrians, bicyclists, automobiles and trucks. The street network over the past two decades has largely been built as the city has grown. These Street Typology recommendations are intended to refresh the inventory street sections that are most likely to be referenced in the upgrading of existing street corridors as development and budgets permit. Individual elements of the street typologies are described in more detail in the following section, Streetscape Facilities.

Each Street Typology describes the following:

Right-of-way (Row)

The range of total cross-section width as measured in feet generally required between property lines to accommodate the street typology

Number of Lanes

The typical total number of travel and turning lanes

Lane Width

The standard width in feet of a travel lane within the street typology

Median/Turning Lane

The standard width in feet of a center median or turning lane, if required or present

On-street Parking

The standard width in feet of on-street parking, if required or present

Tree Lawn

The standard width in feet of the street’s planting area, if required or present

Street Trees

The requirement or option to include street trees on one or both sides of the street

3.1 Street Typologies

  • Conservation Corridors

    To protect private property, privacy, environmental features, and unique aesthetic qualities of context-sensitive corridors, the City of Carmel contains streets with a Conservation Corridor designation. Those will remain as such and continue to be guided by the following priorities when City-funded changes are being planned or designed:
    • Priority 1: Under all circumstances corridor improvements will be designed to the minimum required for vehicular, bicycle and pedestrian safety.
    • Priority 2: Under all circumstances, the installation and maintenance of public utilities and storm water facilities shall be accommodated.
    • Priority 3: Corridor improvements will be designed to minimize negative impacts on private residential properties relative to property value, privacy, and encroachment.
    • Priority 4: Design streets, bicycle and pedestrian facilities with the lowest impact that is necessary to meet the current and future demands.
    • Priority 5: Design streets, bicycle and pedestrian facilities to avoid removal of mature or significant trees and vegetation.
    • Priority 6: Add or replace trees and vegetation after facility improvements are made to buffer private residential properties and/or to replace trees and vegetation that were removed for construction.
    • Priority 7: Achieve priorities 3 through 5 above by installing a pedestrian facility on only one side of the street, where appropriate.
    • Priority 8: Achieve priorities 3 through 5 above by narrowing the typical tree lawns, where appropriate.
    • Priority 9: Include adjacent and nearby private residential property owners in early design discussions.
