Section 1: Establish Existing Conditions



1 Assessing the Lighted Environment

Site Surveys with City Officials:

• Dennis Pay, City Engineer

• Sharen Hauri, Urban Design Director

• Alexandra White, City Planner

• Sgt. Bill Hogan, SSLC Police Department

• Terry Addison, Deputy Fire Chief

Would be safe to walk here, alone, during daylight hours?

Would be safe to walk here,

alone, during darkness hours?

Is the light comfortable?

Do you like the color of the light?

Are light sources glaring?

Is the light uneven?

Supplemental Improvements Comprehensive Improvements

• Acceptable Existing Conditions

• No character district influence

• Lighting meets the needs of the

area

• Moderately Acceptable Existing

Conditions

• No character district influence

• Continuous lighting is warranted,

but non continuous lighting exists

• Unacceptable Existing

Conditions

• Character District calls for

updated lighting

• Lighting is warranted, but not

existing
