Energy documents have been incorporated into the plan set, thank you. The azimuth orientation of the proposed pv array is called out at 180 degrees (South). I encourage the use of the California Flexible Installation (CFI) range, which is 150-270 degrees. This is typically the go -to option for tract construction where it is not possible to achieve one orientation of installation for all homes. 2) PC-1: Energy storage systems (ESS) ready. All single-family residences that include one or two dwelling units shall meet the following. All electrical components shall be installed in accordance with the California Electrical Code: 1. At least one of the following shall be provided: A. ESS ready interconnection equipment with a minimum backed -up capacity of 60 amps and a minimum of four ESS-supplied branch circuits, or B. A dedicated raceway from the main service to a panelboard (subpanel) that supplies the branch circuits in Section 150.0(s)(2). All branch circuits are permitted to be supplied by the main service panel prior to the installation of an ESS. The trade size of the raceway shall be not less than 1 inch. The panelboard that supplies the branch circuits (subpanel) must be labeled "Subpanel shall include all backed -up load circuits." 2. A minimum of four branch circuits shall be identified and have their source of supply collocated at a single panelboard suitable to be supplied by the ESS. At least one circuit shall supply the refrigerator, one lighting circuit shall be located near the primary egress and at least one circuit shall supply a sleeping room receptacle outlet. 3.

Sufficient space shall be reserved to allow future installation of a system isolation equipment/transfer switch within 3 feet of the main panelboard. Raceways shall be installed between the panelboard and the system isolation equipment/transfer switch location to allow the connection of backup power source. PC-2: Comment partially addressed. Note on plans verified, thank you. Please indicate on the single line diagram a backup capacity of 60 amps minimum for the solar panel, and indicate the four required back up circuits and the panel they are to be located in. Refer to code reference above. For reference, 400 amp split main services that have both Residential Plan Check Correction List Page 2 of 3 ceitY Ot4a" main overcurrent devices in the same compartment are no longer permitted in the electrical code (230.71(B)). The single line only shows one throw for the panel, but I believe the services used in the past, on that tract, have been the split main type. Clarify which type of main service is being used.

The lots are located within the "Andalusia at Coral Mountain" development in the City of La Quinta, California. It is our understanding that the proposed residential structures will be of relatively lightweight wood -frame construction and will be supported by conventional shallow spread footings and post -tensioned slabs on grade. The referenced report includes recommendations pertaining to the design and construction of residential structure foundations. Based upon our review of the referenced report, our previous experience on the project site and our understanding of the proposed construction, it is our opinion that the structural values included in the referenced Geotechnical Investigation report remain applicable for the design and construction of the proposed residential structures, except as amended herein. Post -tensioned slabs are planned for the proposed residential structures to mitigate potential liquefaction related differential seismic settlements. We have evaluated the on -site soil for construction of post -tensioned foundation systems in general accordance with design specifications of the Post Tensioning Institute (PTI). Post -tensioned slabs should be designed to be rigid and capable of spanning areas of non -uniform support and meet the following criteria: 1. Bearing Capacity =1500 psf 2. Potential Liquefaction Induced Differential Settlement = 2.25 inches (over a horizontal distance of 100 feet) 3. Coefficient of Friction = 0.40 July 17, 2023 -2- Project No. 544-18139 23-07-365 Auxiliary structures may be supported upon conventional shallow spread footings. Conventional shallow spread footings should be bottomed into properly compacted fill material a minimum of 12 inches below lowest adjacent grade. Continuous footings should be at least 12 inches wide and isolated pad footings should be at least 2 feet wide. Continuous footings and isolated pad footings may be designed utilizing allowable bearing pressures of 1800 psf and 2000 psf, respectively. Allowable increases of 250 psf for each additional 1 foot of width and 250 psf for each additional 6 inches of depth may be utilized, if desired. The maximum allowable bearing pressure should be 3000 psf. The recommended allowable bearing pressures may be increased by one-third for wind and seismic loading. Static settlement resulting from the anticipated foundation loads should be minimal provided that the recommendations included in this report are considered in foundation design and construction. The ultimate static settlement is estimated to be less than one inch when using the recommended foundation bearing pressures. As a practical matter, differential static settlement between footings can be assumed as one-half of the total static settlement. Lateral forces may be resisted by friction along the base of the foundations and passive resistance along the sides of the footings. A friction coefficient of 0.40 times the normal dead load forces is recommended for use in design. Passive resistance may be estimated using an equivalent fluid weight of 250 pcf. If used in combination with the passive resistance, the frictional resistance should be reduced by one third to 0.33 times the normal dead load forces. Retaining walls may be necessary to accomplish the proposed construction. Lateral pressures for use in retaining wall design can be estimated using an equivalent fluid weight of 35 pcf for level free -draining native backfill conditions. For walls that are to be restrained at the top, the equivalent fluid weight should be increased to 55 pcf for level free -draining native backfill conditions. Back drains should be provided for the full height of the walls. Seismic pressures should be incorporated into any retaining walls greater than 6 feet in height. Seismic deign pressures may be provided once specific wall heights and locations are known design pressures can be provided. The seismic design category for a structure may be determined in accordance with Section 1613 of the 2022 CBC or ASCE7-16. According to the 2022 CBC, Site Class D may be used to estimate design seismic loading for the proposed structures. The 2022 CBC Site Specific Seismic Hazard Analyses are attached.
