3 Job Address The following list is now part of the plans and shall be kept attached to the approved plans. The items listed herein are reminders of some of the Codes. Others may be noted by the Inspectors during the course of the job. INSPECTION REQUIREMENTS 1. Overhead Wire Clearance: Electrical service conductors and other open overhead wiring cannot cross over pools/spas within ten (10) feet horizontally or a special cable must be installed. Contact Southern California Edison Company for special cable installation. 2. Main Drain: All types of pools and spas shall have anti-vortex drains with listed outlet covers. Spas are required to have two (2) outlets separated by a minimum of three (3) feet, or located on two different planes. All circulating piping connected to the pool/spa system shall be pressure tested with a minimum of thirty-five (35) pounds constant pressure for 15 minutes. 3. Steel: All reinforcing steel shall be deformed bars conforming to A.S.T.M. A615 graded. All pool construction shall conform to expansive soil details. Minimum clearance between earth and steel to be three (3) inches. A 9 in.² listed bonded plate must be installed, in contact with the pool water, for steel inspection. [2010 CEC (c)] 4.

Backflow Device: Auto-fill valve (usually installed at edge of pool inside a skimmer box) requires a backflow device [CPC ]. We now require a pressure vacuum breaker or reduced-pressure backflow preventer, as no valves can be downstream of an atmospheric vacuum breaker. The pressure-type device must be installed, tested and certified by a licensed backflow technician before final signoff and then certified yearly, thereafter. Public Works inspects backflow devices, please call ext.5306 IMPORTANT: Upon completion and Inspector s approval of the above items, pool may be gunited. 6. During Placement of Shotcrete: All swimming pools and spas utilizing shotcrete (gunite) will require special inspection in accordance with Section (12) CBC. The special inspector shall demonstrate that he/she is qualified to inspect the work by submitting evidence of appropriate certifications prior to reporting to the job site. The special inspector shall be present during the taking of test specimens and placing of all shotcrete (gunite). The special inspector is required to provide continuous inspection of the placement of the reinforcement and shotcrete and shall submit a statement indicating compliance with the plans and specifications. Strength test report shall be submitted prior to final inspection approval. The special inspector must be have a City of Manhattan Beach Business License. Page 3 of 7
