City of Santa Ana accurately characterize subsurface permeability. These tests will be done in accordance with the Orange County Technical Guidance Document (TGD). The laboratory testing program for soil may Include, but not be limited to, the following: In-place dry density (ASTM D2937); ai In-place moisture content (ASTM D2216); t-3 Particle -Size Distribution (Gradation) (ASTM D6913); m Atterberg Limits (ASTM D4318); Expansion index (ASTM D4829); Direct Shear (ASTM D308D); Unconfined Compression (ASTM D2166); r R -value (CTM 301); and Corrosion potential (including pH, minimum resistivity, soluble sulfates and soluble chlorides tests, in accordance with Cal DOT Standard Test Nos. 643,417 and 422). We will review the field and laboratory data, and perform engineering analysis for pavement design. We will prepare a report that includes the results of our Investigation, and our conclusions and geotechnical recommendations for pedestrian and landscape improvements. Our report will Include a site plan, boring logs, and laboratory test data, in addition to the following information: Site Conditions: We will review surface, subsurface, and groundwater conditions, and the engineering properties of the soils encountered during the site Investigation, and obtained from the existing data review and our field Investigation and laboratory tests. Geological hazards, maps, seismicity requirements, foundation and wall design, earthwork handling criteria, temporary excavation and shoring guidelines, pavement and ELECTRICAL AND LIGHTING DESIGN During the Conceptual Design phase our experienced electrical design team will consider two options for the project. The first option will bring 24 DESIGN SERVICES RFP NO.: 18.042 power from a nearby Southern California Edison (SCE) power source while the second will use light poles with built in solar panels and batteries. Each option is discussed In further detail below. Capital costs, operation and maintenance costs, as well as operation and maintenance requirements will be developed for each option and presented to the City Option 1: This option will bring permanent power from SCE to power the pathway LED light poles. We will coordinate the electrical service with an SCE planner and submit all the necessary forms and drawings to obtain power from SCE. Power from SCE will Include setting the meter pedestal per SCE design adjacent to the pathway. We will then run underground conduits and wires as needed to power the light poles, irrigation system controls, and the pedestrian traffic signals across the railroad tracks. Because the new light poles will be LEDs, energy consumption will be lower when compared with older types of light poles. Light poles will have individual photocells so each pole will turn on independently to increase reliability. The electrical design will include performing photometric calculations and to ensure proper selection of light poles. Option 2: In this option we will look into using solar power (PV) light poles equipped with battery packs. The pole will consist of an LED light fixture, pole mounted PV panel and a battery pack panel also installed on the pole. This option will not. require power from SCE and the light poles will be running strictly on solar panels. The solar panel will charge the batteries during the day while the lights are off. The light will come on at dark and use energy stored in the batteries to power the lights. This option doesn't require underground conduits, trenching or coordination with SCE. However, this option requires more maintenance because the batteries have limited life and PV panels may require periodic cleaning. We will also Include photometric calculations to ensure adequate lighting. 25F-39
