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 contractor’s 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.
