EROSION CONTROL NOTES
General Requirements for Erosion Control:
A schedule of operations to include starting and completion dates for
major development phases, such as land clearing and grading, street,
sidewalk, and storm sewage installation, etc.
Seeding, sodding, or revegetation plans and specifications for all
unprotected or unvegetated areas shall be implemented as soon as
possible.
Excavations, Fills and Grading:
Cut and fill slopes shall not be steeper than 3:1 unless stabilized by
a retaining wall or cribbing, except as approved by the Commission
under special conditions.
Adequate provisions shall be made to prevent surface water from
damaging the cut face of excavation or the sloping surfaces of fills.
Cut and fills shall not endanger adjoining property.
Fill shall be placed and compacted so as to minimize sliding or erosion
of the soil.
Grading shall not be done in such a way so as to divert water onto
the property of another landowner without the expressed consent of
that landowner and the Commission.
Fills shall not encroach on natural watercourses or constructed channels.
During grading operations, necessary measures for dust control shall
be exercised.
Grading equipment will not be allowed to cross live streams except by
means of bridges and culverts or other methods as approved by the
Commission.
Implementation Procedures:
Wherever feasible, natural vegetation should to retained and protected.
Only the smallest practical area of land should be exposed at any
one time during development.
When land is exposed during development, the exposure should be
kept to the shortest practical period of time,.
Where necessary, temporary vegetation and/or mulching should be
used to protect areas exposed during developrnen-t.
The permanent final vegetation and structures should be installed
as soon as practical in the development.

CONSTRUCTION NOTES
No change in plan location or elevation shall be made without notifying
the engineer and proper Town authority.
The engineer shall be notified prior to construction to set location and
grade stakes for the subsurface sewage disposal system to include; fill
material, septic tank, primary leach system. Similiar staking required
for all curtain and foundation drains and well.
No soil stripping or excavation shall begin within the area of the
subsurface sewage disposal system without a valid construction permit.
A licensed sewage disposal system installer shall obtain a construction
permit and arrange for a site inspection prior to construction. The
system shall be installed in accordance with this plan and all applicable
State and Local rules, regulations, and codes.
Topsoil to be stripped and stockpiled prior to any filling. Scarify area
before filling. Avoid stripped area with heavy vehicles on wheels to
minimize compaction. Place fill at edge of prepared area and spread with
bulldozer in 6' lifts and compact to 90% maximum density.
Fill material shall be clean bankrun sand or gravel with no more than
5% fines passing a 200 mesh sieve.
Sanitarian to inspect any fill over 24" deep prior to construction.
Trench bottoms shall be level and set to follow contours of existing
grade. Trench laterals shall be laid level with perforations downward.
No construction below original grade in the leach system area shall take
place within 48 hours of a rainstorm or with standing puddles.
All footing drains, curtain drains and subsurface sewage disposal system
components shall be inspected by the Town and located "AS -BUILT' by
the engineer/land surveyor prior to covering. Inspection shall be within
2 working days following timely notification by the contractor.
Contractor to protect open work from siltation and erosion.
All disturbed areas shall be graded, loamed, and seeded as soon as
possible after construction. If seeding cannot take place during the
growing season, a temporary mulch cover shall be placed and maintained
until permanent cover can be established.
A licensed well driller shall obtain a permit prior to any drilling. The
well shall be provided in accordance with this plan and all applicable
State and Local regulations and codes.
Satisfactory completion of all the above requirements shall preceed the
final inspection and approval of the subsurface sewage disposal and well,
