City of Santa Ana <br />accurately characterize subsurface permeability, <br />These tests will be done in accordance with the <br />Orange County Technical Guidance Document <br />(TGD). <br />The laboratory testing program for soil may include, <br />but not be limited to, the following: <br />In -place dry density (ASTM D2937); <br />In -place moisture content (ASTM D2216); <br />Particle -Size Distribution (Gradation) (ASTM <br />D6g13); <br />Atterborg Limits (ASTM D4318); <br />Expansion index (ASTM 04829); <br />Direct Shear (ASTM D3080); <br />Unconfined Compression (ASTM D2166); <br />R-value (CTM 301); and <br />Corrosion potential (including pH, minimum <br />resistivity, soluble sulfates and soluble chlorides <br />tests, in accordance with Cal DOT Standard Test <br />Nos, 643, 417 and 422). <br />We will review the field and laboratory data, and <br />perform engineering analysis for pavement design, <br />We will prepare a report that includes the results <br />of our investigation, and our conclusions and <br />geotechnical recommendations for pedestrian and <br />landscape improvements. Our report will Include <br />a site plan, boring logs, and laboratory test data, in <br />addition to the following information: <br />Site Conditions; We will review surface, subsurface, <br />and groundwater conditions, and the engineering <br />properties of the soils encountered during the site <br />Investigation, and obtained from the existing data <br />review and our field Investigation and laboratory <br />tests. Geological hazards, maps, seismicity <br />requirements, foundation and wall design, <br />earthwork handling criteria, temporary excavation <br />and shoring guidelines, pavement and <br />ELECTRICAL AND LIGHTING <br />DESIGN <br />During the Conceptual Design phase our <br />experienced electrical design team will consider <br />two options for the project. The first option will bring <br />24 DESIGN SERVICES REP NO.: 1&042 <br />power from a nearby Southern California Edison <br />(SCE) power source while the second will use light <br />poles with built in solar panels and batteries. Each <br />option is discussed in further detail below. Capital <br />costs, operation and maintenance costs, as well as <br />operation and maintenance requirements will be <br />developed for each option and presented to the City <br />Option 1: This option will bring permanent power <br />from SCE to power the pathway LED light poles, <br />We will coordinate the electrical service with an <br />SCE plan nor and submit all the necessary forms <br />and drawings to obtain power from SCE. Power <br />from SCE will include setting the meter pedestal <br />per SCE design adjacent to the pathway. We <br />will then run underground conduits and wires as <br />needed to power the light poles, Irrigation system <br />controls, and the pedestrian traffic signals across <br />the railroad tracks, Because the new light poles <br />will be LEDs, energy consumption will be lower <br />when compared with older types of light poles, bight <br />poles will have individual photocells so each pole <br />will turn on independently to increase reliability, The <br />electrical design will include performing photometric <br />calculations and to ensure proper selection of light <br />poles, <br />Option 2: In this option we will took into using <br />solar power (PV) light poles equipped with battery <br />packs. The pole will consist of an LED light fixture, <br />pole mounted PV panel and a battery pack panel <br />also installed on the pole. This option will not <br />require power from SCE and the light poles will be <br />running strictly on solar panels, The solar panel <br />will charge the batteries during the day while the <br />lights are off. The light will come on at dark and <br />use energy stored in the batteries to power the <br />lights. This option doesn't require underground <br />conduits, trenching or coordination with SCE. <br />However, this option requires more maintenance <br />because the batteries have limited life and PV <br />panels may require periodic cleaning. We will also <br />Include photometric calculations to ensure adequate <br />lighting. <br />
