Required Equipment Public Sewer Lines Up to and Larger than 6 9/32 = SDR 26 in the city right of way Private Sewer Lines Less than or equal 4 9/32 = Schedule 40 Larger than or equal 6 9/32 = Schedule 40 Approved connections Furnco PVC 21. Inspection Public The Department of Engineering is responsible for inspection to the private property line /ROW line and /or easement line. Tests Required: 4 -psi low air pressure test TV comera all public lines Mandrill test required 30 days after bockfill of pipe trench Manholes require vacuum test 3 min P 10Hg Forced main requires 1 hour @50 psi Note: The contractor can wait to do the air pressure test when the mandrill test is done or a preliminary mandrill test can be done after bockfill and before the air pressure test to help contractors schedule repairs if there is o failure in the mandrill test. Private The Building Department is responsible for inspection on private property Low - pressure air test with 5 PSI on all lines or 105 /32 hydrostatic 22. Notes - General All sewer lines to be installed 9' minimum from any water line in a public way and 5 "'minimum from any water line on private property. Contact Engineering or Building Department for alternate standards. Any service top serving more than one lot must hove clean -outs located no less than six foot apart at the property line. All man holes to be cored (not chiseled). All manholes, on public end private land, to be tested at 10mo vacuum prior to lining the manhole. All wastewater manholes installed on public and private land, are to be lined (coated) All individuals that enter on active wastewater manhole must wear a safeiv harness connected t -o a mechanical retrieval device. All installed pipe will have letters /numbers at the 12:00 positions when installed The City will not perform the tie -in of lines to City owned and maintained lines or clean -outs. It is the licensed plumber /utility contractor responsibility to maintain proper slope, connection and drainage of system to the public connection. See city details for all sewer /utility line installations. DRIVEWAYS AND SIDEWALKS 23. Inspection - All sidewalks and driveway approaches will be inspected by the City of Son Marcos.

All meters must be located on a public right of way or easement given by the owner (and legally recorded) of the property. Meters and other utility obstructions must be relocated by and at the expense of the owner or contractor. Driveway access grade at sidewalk cannot exceed 2% cross slope. Curb cut to front of sidewalk cannot exceed 10% normal.

Building inspection will complete all sidewalk construction and driveway access in development "build out" (less than three -plex) after release of subdivision by Engineering. All sidewalks and driveways shall meet applicable ADA and TAS standards. STREET CONSTRUCTION 25. Inspection - All new street construction in public right of way and easements will be inspected by the Engineering Dept. 26. Notes Subgrade shall be scarified to 6 inches below finished subgrade elevation and compacted to required density. For subgrade soils with a plasticity index of 25 and above, the following measures should be adopted: 1) A recommendation from on approved testing Ioboretory. 2) Subgrade must be replaced with 18 inches of approved material with a P.I. less than 15 and more than 4. 3) Lime stabilize a minimum of 8 inches of subgrade. 4) Increase the thickness of the designed flexible limestone base by 50%. Subgrade must be at a minimum density of 95% of optimum and have o moisture content that is within 3 percentage points above or below optimum. After the subgrade has been shaped and graded to final grade then it shall be proof rolled to locate unstable areas. Flexible base material shall be placed in a minimum of 2 lifts not to exceed 6 inches in each compacted lift. Flexible base must be at a minimum density of 100% and hove o moisture content that is within 3 percentage points of optimum. The final lift of base shall be smooth and in conformity with lines and grades shown on the plans. Prior to placing asphalt on the completed base, the base shall be cured to the extent directed by the engineer or his field representative. Valve risers and manhole castings shall be raised to finished elevations. Backfill in streets for manholes shall be cement stabilized sand (2 sacks per cubic yard) and shall be a minimum of 12 inches thick. Cutback Asphaltic material (Prime Coat) sholl be applied to the completed base course and allowed to set 24 hours before paving the roadway. An Emulsified Asphalt Took Coot con be used in lieu of the prime coat and /or placed on the prime coat. Asphalt must be at a temperature of between 120 C and 175 C when discharged from the mixer and compacted using steel -wheel rollers, vibratory rollers and Pneumatic-tire rollers. The contractor or his testing technician shall check the density of the compacted asphalt at regular intervals. Samples of the asphalt should be taken as the asphalt leaves the hamper of the paving machine before compaction and cores shall be taken at these sampling locations.
