Editor's Note: See Ch. 330, Subdivision and Land Development.
These regulations constitute the "Township Specifications" to which reference is made in Chapter 330, Subdivision and Land Development, and elsewhere.
These regulations shall govern all construction or reconstruction of any new or existing roads or streets in the Township. Regulations in the latest edition of Form 408 and in Bulletin 25 shall govern all materials and procedures, unless otherwise specified in this or any other Exeter Township ordinance.
A. 
Subgrade drains, pipe underdrains, pipe culverts, concrete box culverts and bridges shall be placed as required by the Township Engineer.

C. 
Catch basins and manholes shall conform to crown and grade and shall be set one inch and 1/2 inch, respectively, below final grade.
D. 
Catch basins and manholes shall be concrete; precast or cast-in-place concrete only shall be used for final adjustment of tops.
E. 
A concrete "channel" shall be placed in the bottom of catch basins to provide self-cleaning.
F. 
Culs-de-sac shall be designed to keep all drainage along the curbs; no cross flows.
G. 
All pipe placed in existing or proposed Township property shall be reinforced concrete. SL. C.P.P. may be permitted, subject to approval by the Township.
H. 
Catch basins that exceed five feet in depth shall be equipped with aluminum steps.
A. 
Unless specifically authorized by the permit, the permittee shall not:
(1) 
Alter the existing drainage pattern or the existing flow of drainage water.
(2) 
Direct additional drainage of surface water toward, onto or into or in any way affect the street right-of-way or street facilities.
B. 
The issuance of a permit does not authorize the permit to direct, divert or otherwise drain surface waters over the property of any other property owner.
(1) 
The issuance of a permit does not in any way relieve the permittee from acquiring the consent, permission or other authorization from any property owner who may be adversely affected by drain alterations.
(2) 
The permittee is responsible for any damage caused to any private or public property as a result of work done under the permit.
Design of all streets constructed shall be in accordance with the guidelines and requirements for design of local roads and streets contained in Design Manual, Part II, Highway Design, latest revision, and PennDOT Publication No. 408, 2000 Edition or latest. The following procedures shall be followed for construction:
A. 
Local streets.
(1) 
If, at the time of construction, local, unstable subgrade conditions are encountered, the Township Engineer may require that all areas of unstable subgrade be excavated to sufficient depth, replaced with approved material and compacted to a density and stability equal to or greater than the surrounding subgrade. The Township Engineer may require PennDOT Class 4 geotextile in accordance with § 735 of PennDOT No. 408 specifications to be installed for the entire subgrade of the proposed cartway. Pavement base drain may be required by the Township Engineer.
(2) 
Fine grade and roll subgrade.
(3) 
Cut out all soft and yielding areas to a maximum depth of two feet and backfill with 2A modified or 3A modified crushed stone compacted in six-inch lifts. If the soil is still soft at the two-foot depth, place geotextile fabric in the bottom prior to backfilling with 2A or 3A modified crushed stone.
(4) 
Place and compact a minimum six-inch depth of 2A modified crushed stone.
(5) 
Place and compact a minimum 1 1/2 inches of Superpave asphalt design, 9.5 mm, PG 64-22 wearing course. The appropriate skid resistance level shall be used in accordance with PennDOT Publication Nos. 408 and 242. The design mix shall be submitted to the Township for review to include appropriate ESAL.
B. 
Industrial, commercial, arterial and collector streets.
(1) 
If, at the time of construction, local, unstable subgrade conditions are encountered, the Township Engineer may require that all areas of unstable subgrade may be excavated to sufficient depth, replaced with approved material and compacted to a density and stability equal to or greater than the surrounding subgrade. The Township Engineer may require PennDOT Class 4 geotextile in accordance with § 735 of PennDOT No. 408 specifications to be installed for the entire subgrade of the proposed cartway. Pavement base drain may be required by the Township Engineer.
(2) 
Fine grade and roll subgrade.
(3) 
Cut out all soft and yielding areas to a maximum depth of two feet and backfill with 2A modified or 3A modified crushed stone compacted in six-inch lifts. If the soil is still soft at the two-foot depth, place geotextile fabric in the bottom prior to backfilling with 2A modified or 3A modified crushed stone.
(4) 
Place and compact a minimum six-inch depth of 2A modified crushed stone.
(5) 
Place and compact a minimum five-inch depth of Superpave asphalt design, 25.0 mm, PG 64-22 base course.
(6) 
Place and compact a minimum two-inch depth of Superpave asphalt design, 19.0 mm, PG 64-22 binder course.
(7) 
Place and compact 1 1/2 inches of Superpave asphalt design 9.5 mm, PG 64-22 wearing course. The appropriate skid resistance level shall be used in accordance with PennDOT Publication Nos. 408 and 242. The design mix shall be submitted to the Township for review to include appropriate ESAL.
C. 
Playground paving. The same procedure shall be followed for playground paving as for minor streets.
D. 
All streets shall be crowned at 1/4 inch per foot.
E. 
All thicknesses are final, compacted thicknesses.
F. 
All thicknesses are minimums.
G. 
Core samples of pavement shall be taken as directed by the Township Engineer and testing performed at the expense of contractor.
H. 
All sections failing to meet the minimum required thickness shall be overlaid to make up the shortfall unless this would result in unacceptable loss of curb reveal, in which case the section shall be removed and rebuilt according to specifications.
I. 
Sump pumps shall not discharge to the street or in such a way as to reach a street.
J. 
Sump pumps shall discharge onto the same property, or be tied directly to a storm sewer with Township permission.
K. 
No natural gas mains, water mains, petroleum pipelines, storm sewers or sanitary sewers shall be placed between the curbline and the right-of-way line.
A. 
Shoulder construction shall consist of constructing supporting shoulders on the sides of all roads and streets within the Township where curbing shall not otherwise be required.
B. 
Shoulders shall be constructed as required by the Township and shall be PennDOT Type 6-1 paved shoulders as in Publication No. 408, § 656, latest revision. Additional shoulder designs may be approved by the Township Engineer where deemed necessary.
