SUBJECT:  SPECIAL STREETLIGHTING STANDARDS FOR THE COMMUNICATIONS HILL PLANNED COMMUNITY

 

 

RECOMMENDATION

 

Adoption of a resolution amending Resolution No. 63396 adopted on December 10, 1991, which sets streetlighting standards for new development, to provide for special streetlighting design standards for the Communications Hill Planned Community.

CEQA:  Resolution Nos. 63624 and 70194, PP03-09-306.

 

 

BACKGROUND

 

Communications Hill is one of the most visually prominent features in Santa Clara Valley.  The largely undeveloped slopes of Communications Hill itself total about 500 acres and rise over 300 feet above the surrounding valley floor. Council adopted a Specific Plan for Communications Hill in April 1992. The objective of the Communications Hill Planned Community is to provide a comprehensive planning framework for development of a unified, high-density, pedestrian-oriented, urban community with a mix of uses on and around Communications Hill. The Communications Hill Planned Community has also been incorporated in the 2020 General Plan.  Attachment A shows a map of the Planned Community.

 

 

ANALYSIS

 

One of the key elements identified by the Communications Hill Specific Plan is “walkable streets”. As stated in the Specific Plan, “Streets are walkable if their widths, traffic volumes, landscaping, parking arrangements, lighting and sidewalk design serve walkers and if the buildings that enfront streets give them life and vitality.”  Streetlighting plays an integral part in the design of “walkable streets”.

 

To implement the vision of the Specific Plan and create comfortable pedestrian-oriented streets, continuous streetlighting will be installed on all public streets.  To add character to the streets, the Planned Development Permit for the hilltop development further requires that pedestrian-scale ornamental electroliers be installed on all public streets except the main collector Communications Hill Boulevard.  A unique ornamental fixture was evaluated and selected by the City for use in this development. Attachment B shows an image of the selected fixture. Maintenance of these unique fixtures is included in the community facilities district which has been established for this planned community.

 

The City of San Jose’s current streetlighting design standard for subdivisions in Resolution 63396 is not well suited for the intended hilltop development. The current resolution references the American Standard Practice for Roadway Lighting published by the Illuminating Engineering Society (IES) in 1964 as the streetlighting design standard for subdivisions. Due to the Hill’s uniqueness and prominence in the valley, an excessive number of streetlights will produce significant light pollution at night and create undesirable visual effects from dusk to dawn when viewed from the valley floor.

 

A study was conducted by Alliance Engineering Consultants under City direction and in cooperation with developers of the Communications Hill site in search of a more suitable lighting standard for this development.  The study included a survey of the current practices of various cities in their hillside/hilltop developments, and an analysis of streetlighting practices recommended by the Illuminating Engineering Society (IES). A summary of the study is attached to this memo for Council’s information. (See Attachment C)

 

Based on the findings of the study and recognizing the objective of creating pedestrian-oriented streets, a modified streetlighting standard is proposed for the streets in the hilltop development (see Attachment B).  The proposed streetlighting standard deviates from the City’s adopted standards in that a slightly lower lighting level is recommended for the local streets and intersections in the hilltop development. However, it is at the high end of the range of the streetlighting levels employed by the cities surveyed.

 

The proposed streetlighting level reduces the number of required electroliers to be installed, therefore reducing light pollution at night and minimizing the undesirable visual effects.  It is expected that the high-density dwelling structures will also provide a significant amount of ambient light onto the streets during nighttime hours with high pedestrian traffic. Combined with the output from the pedestrian-scale streetlights, this will create a well-lit and comfortable walking environment.

COORDINATION

 

This memorandum, lighting study, and proposed resolution amending Resolution No. 63396 have been coordinated with the City Attorney’s Office, the Department of Planning, Building and Code Enforcement, and the Department of Transportation, as well as the Communications Hill landowners and developers.
