a. Reinforced Concrete Pipe (RCP) shall conform to AS'rM C76 -70, Class
III latest revision, with joints conforming to ASTM C -433 latest revision.
b. Corrugated Metal Pipe (CMP) shall be standard helical pipe with a
minimum thickness of 0.05 inches. CMP shall only be used to extend
existing CMP to the nearest proposed structure.
C. All manholes and inlets shall be precast concrete conforming to AS 'ITT
C -478 latest revision.
d. Castings shall conform to ASTM -48 latest revision.
2. Subsurface drains shall be 6- inches in diameter located directly below the
pavement /curb joint and shall run continuously at a minimum 0.20% slope along
both sides of the street and shall be connected only into storm sewer structures.
3. There shall be a subsurface drain connection provided for each lot.
GENERA I. NOTES
I. It shall be the responsibility of the contractors to determine the location of
existing underground utilities 24 hours prior to any construction or excavating and
maintain operating conditions of active utilities. The engineer shall not be
responsible for any damage caused by an erroneous location shown or by tale
omission of a utility location on these plans. The developer shall be responsible
for all approvals, permits do easements.
2. Construction of private driveways is not included in this project.
3. The contractor shall, at t!le direction of the developer, endeavor to save and
protect All trees of value and worth which d0 not impair construction of
improvements as designed. In the event cut or fill exceeds 0.5 foot over the root
area, the developer shall be consulted with respect to protective measures to be
taken, if any, to preserve such trees.
4. Remove topsoil to a depth determintd by the soils report from all street rights -of-
way and building pad areas. Topsoil shall be slored at a location designated by
the engineer.
5. The casting elevations are set by plan. however, the castings are to be Rdiusted
in the field by file engineer's representative, should a discrepancy occur between
plan grade and existing grade. New manhole ring and cover shall be installed to
establish grade. Maximum height of adjusting rings shall be 12- inches.
6. Backfill around all structures and all cuts under paved areas with granular
material. Trenches opening within 5 -feet of paved roadways shall be backfilled
with granular material in accordance with Section 211. backfill tinder sidewalks
shall be granular, unless the walks are constructed a minimum of 6 months after
backfill has been in- place.
7. The Contractor shall be responsible for verifying that all state highways, city and
county permits have peen obtained by the developer prior to start of construction.
8. The Contractor shall be required to furnish the developer's ingineer with a set
of prints, marked in red pencil, .1howillg actual sewer location and invert, In
include lateral location, depth and length, such 'as- built' prints must be received
by the Engineer before the final contract payment can be aulhorized. The
sanitary sewer laterals and slubs termination shall be indicated on the surface with
R Illelal fence post set inlnledialely above said termination point.
9. All sanitary sewer lines upon completion will be required 10 pass an infiltralion
weir test and a low pressure air test, unless otherwise directed by the engineer.
said lest shall be conducted according to NCPI Standard Method, and shall be
witnessed by an engineer and a representative of the Clay Waste dis(rict.
10. I)eflection tests shall be performed on all flexible'" pipe after the final backfill has
been in -place at least 30 days. No pipe shall exceed a vertical deflection of 5
percent deflection test results. (• The following are considered no- flexible pipes:
concrete pipe, ductile iron pipe and cast iron pipe.) The deflection lest shall he
performed with a nine -point mandrel. Proving rings Shall be Available.
I I.. All mandrel telling shall be observed by it professional Engineer for certification
and A representallVe of the Clay Waste Uislricl.
12. The ends of laterals are to be plugged light with a braced plastic disc or cap
capable of withstanding a low pressure air test withoul leakage.
13. Bedding for flexible pipe shall be No. 8 stone from 6- inches below the pile to
12- inches above the pipe. Bedding for rigid pipe shall be No. 8 clone from 6-
inches below the pipe to the spring line of the pipe and from this point to 12-
irlclles above Oil no less (hall 6-iilchel of stone bedding.
14. Water and sewer line crossings and separations shall he in accordance with Ten
Slates' Standards.
