            "text": "This is City of Palmdale Standard Detail 1-9, titled \"TYP. SHRUB HEAD ASSEMBLY,\" a pictorial drawing of an underground irrigation sprinkler installation beside a sidewalk, curb, or similar edge, with finish grade shown and labeled callouts. The drawing is a connected assembly, so the arrangement of the parts matters. Reading from top to bottom: at the top sits the SPRINKLER NOZZLE, which sits on the POP-UP BODY ASSEMBLY (labeled \"INSTALL 1/2\" ABOVE FINISH GRADE\"). Below the pop-up body is a PVC SCH. 80 NIPPLE, labeled \"LENGTH AS REQUIRED,\" which runs down vertically. The nipple connects at its bottom to a SCH 40 PVC STREET ELBOW, which turns the flow horizontally into a SCH.40 PVC ELBOW. That elbow connects to a FLEX RISER (MIPT x MIPT), labeled \"4\" LONG.\" The flex riser runs to a PVC TEE OR ELBOW (S x S x T), and the tee's run continues as a LATERAL LINE, labeled \"SIZE AS NOTED ON DRAWING.\" Dimension lines show the sprinkler nozzle set \"4\" OR AS NOTED\" from the sidewalk, curb, or similar edge, and a vertical dimension of 12\" from the finish grade down to the lateral line. A note at the bottom reads \"NOTE: USE TEFLON TAPE ON ALL THREADED FITTINGS.\" The drawing's title block shows CITY OF PALMDALE, Engineering, Planning and Public Works approval, \"APPROVED BY ABOVE,\" \"DATE IMPLEMENTED 1-10-91,\" and a REVISIONS box, with the detail number I-9. The note and title block sit outside the assembly flow.",
