All public improvements shall be shown on separate
plans to be included in the development plan submission. Public improvement
plans shall be prepared as if they were a separate bid package since
this work will be both inspected and accepted by the Township.
|
|
Requirements for the preparation of plans are
given in this section. While these requirements are directed toward
the preparation of roadway plans, similar procedures shall be followed
for other public improvements (drainage systems, detention basins,
etc.). The applicant shall meet with the Township Engineer to determine
any necessary modifications from these standards for a particular
improvement.
|
|
The Township will make available to the applicant
copies of standard legend sheet and the Township standard details
for inclusion in the construction documents.
|
|
All plan sheets shall be turned over to the
Township prior to the Township's acceptance of the public improvement(s).
The material turned over to the Township shall include all survey
notes, calculations, plan sheet originals and the original specifications
(or a signed and sealed unused copy), and shall reflect "as built"
conditions.
|
|
In general terms, documents submitted for preliminary
approval should represent graphical solutions, for final approval
or prior to beginning construction should represent complete plans
and specifications, and at the time of acceptance should be "as built"
plans. At the time of final approval, or prior to beginning construction,
a detailed estimate of quantities shall be provided, reviewed and
approved by the Township Engineer.

All contract plans shall be prepared in Pelican
"T" ink on a dimensionally stable base material 0.003 inch to 0.004
inch thick (K & E Herculene or equivalent). Cross-sections shall
also be prepared in ink on a stable base material. The overall sheet
size, edge to edge, is to be 24 inches x 36 inch and shall be 23 inch
x 33 1/2 inch inside of borders. The sheet, title box and revision
box shall be as detailed in Figure 801, located at the end of this
chapter.
|
|
The title box shall be in the lower right hand
corner of the sheet and shall be of the size shown in Figure 801.
The wording in the title box shall be as shown in Figure 802 depending
upon the particular project involved.
|
|
On all plan sheets, the minimum size lettering
to be used shall be No. 5 or 140 Leroy. As the plans may be reduced
to half the size, this is the minimum size lettering which will produce
a clear, legible text after reduction.
|
|
Symbols and line weights shall be as shown in
the standard legend sheet. In the preparation of the plans the use
of drafting aids will be allowed. If rub-ons, tapes and "zip-a-tone"
screening are used, the symbol must exactly duplicate that shown in
the standard legend. The applicant is cautioned that before a final
submission can be made, any sheet which contains tapes, rub-ons, etc.
must be photographically Reproduced on a stable material. The Township
will not accept as an original tracing any sheet with aids attached
to it, nor will the Township accept any sheet which is poorly reproduced.
The shadows from tapes or overlays are not to be visible on the final
product. Prior to using any tapes or rub-ons, they are to be submitted
for approval as to size and symbol.

|
Reference is made to the Township standard details
as a supplement to contract plan sheets.

Two hundred feet of topographic coverage beyond the
beginning and end of the contract shall be shown.

shall be shown.
h.
Existing and proposed pavement, curbs, sidewalks,
guard rails, etc shall be shown.
i.
All existing and proposed drainage shall be indicated
with flow arrows. Drafting should differentiate between existing and
proposed features, types of ditches, rip-rap, types of existing and
proposed pipe, and length of proposed pipe between structures (inlets,
manholes, etc.), and underdrains.
j.
Using the standard legend, existing and proposed utilities
shall be shown, including the treatment of existing utilities, if
utility work is to be done by others, indicate by whom (Public Service,
Commonwealth Water, etc.).
k.
Match lines shall be labeled by stations and matching
plan sheet numbers shall be given.
l.
All overhead and underground power and telephone wires,
both existing and proposed, shall be shown.
m.
If detours or temporary construction access roads
are involved, reference to the detour sheet shall be made on the appropriate
plan sheet.
n.
For special treatments, cross references shall be
made to appropriate sheets.
[Ord. #585, § 802C]
The applicant shall meet with the Township Engineer
to determine whether grading plans or cross-sections are to be used
to show earthwork. If cross-sections are required, contouring may
still be required to show intent for areas such as intersections,
stream crossings, etc.
a.
Grading plans shall be to the same scale 30 inches
and cover the same area as the plan sheets.
b.
The title of the sheet shall contain a number which
is to be keyed to the appropriate plan sheet number (i.e. plan no.
10 shall cover the same area as grading plan no. 10).
c.
Match lines shall be labeled as to station and matching
grading plan sheet.
d.
Topography shall be shown on the plan sheets with
the addition of existing contour lines at intervals of one foot.
e.
Existing and proposed utilities shall be shown in
accordance with the standard legend.
f.

shown.
h.
Existing and proposed drainage shall be shown in accordance
with the standard legend.
i.
Proposed inverts, grate elevations, pipe sizes and

tabulation sheets, all drainage structures, flared end sections, headwalls,
etc. shall be assigned structure numbers for cross-referencing between
the grading plans and drainage tabulation sheets.
j.
Generally, one foot contours are to be shown for all
pavement and slope areas. However, for relatively flat pavement areas,
contours at one-tenth (0.1), two-tenths (0.2), or five-tenths (0.5)
foot intervals may be required to adequately define the surface. For
uniformly graded slopes, only the five foot contours need be shown.
One foot contours are required in variable areas, flat areas and for
meeting existing contours.
k.
If applicable, muck excavation or overload limits
with appropriate symbols shall be shown and labeled.
l.
