Some sample guidelines for designing
civil plans are:
Clearly identify and
reference the limits of all project
related contract work including site
lighting, landscaping, paving, utility
system connections and improvements to
specific benchmarks, property lines and
existing significant site improvements
with dimensioning.
Locations of buildings,
site improvements (including shoring
needed to develop structures or
features), underground and sub-surface
structures shall be referenced to
specific benchmarks, property lines or
existing significant site improvements
with dimensioning.
All grades, slopes,
required cuts and fills shall be
appropriately showed, dimensioned and
quantified. Over-excavation requirements
shall be defined with both horizontal
and vertical dimensions sufficient for
accurately calculating cut and fill
quantities.
Plans shall clearly
identify locations for staging of
construction materials, site access for
the contractors workforce and delivery
of materials and temporary fencing and
barricades for site security and safety. |

Provide retaining wall details on plans, show:
surface drains, subsurface drains, slope.
Provide a minimum safety
factor of 1.5 against
sliding and overturning.
The number of retaining walls and their height
is limited to one 12' high wall or two 10' high
walls at minimum 3' apart.
Provide hydrology calculations to justify
drainage design. Calculations shall be based on
the proper 50-year isohyetal method.
Detail pad elevations to provide minimum of 2%
drainage to street.
Detail on plan methods proposed to intercept
and carry off subsurface water.
Show on plans: subdrains required for fill
placed in natural water courses.
Provide 8' paved interceptor terrace drains at
25' vertical intervals. Drain gradients may vary
from 5 to 12 percent, but changes in gradient
must increase in the direction of flow.
Provide a 20' wide bench every 100' of slope
height (cut or fill). Retaining walls are not
allowed to reduce this height.
Provide 6' paved diverter terraces along top
of graded slopes.
Single run of slope interceptor terraces are
not to exceed 150' to a down drain.
Show existing drainage devices on adjacent
tracts.
Provide an approved
outlet structure for all down drains, to consist
of velocity reducers, diversion walls, rip-rap,
concrete aprons or similar energy dissipater.
Concentrated drainage to
be discharged into an approved location.
(Drainage required into street, natural
watercourse, drainage easement or other approved
location).
The use of dispersal wall to discharge water
to areas other than street or natural
watercourse is not allowed.
Drainage across interior lot lines creating
cross-lot drainage is not permitted nor are
changes in the drainage pattern which alter or
increase quantity of water discharging to
adjoining properties.
Distribute all utilities
such as Domestic water, Industrial water,
Natural gas, and Electricity.
