SITE PLANS

Site plans ensure that a development is compatible with the natural environment, that technical and regulatory guidelines are followed and contibutes to a safe, functional and visually attractive environment.  Critical area site plans address environmentally sensitive areas such as steep slopes, woodlands, lakes, ponds, streams, shore buffer, floodplains, and wetlands as defined by local code.

The Engineering Department Staff at Cascade Surveying & Engineering, Inc., consists of a Professional Engineer along with several project managers, engineering technicians and AutoCAD drafters.  Under the coordination of Randall Devoir and our new Engineer In Training, Daniel Howe, the department provides multiple civil engineering services for residential, commercial and government projects through the implementation of advanced design technologies including hydrologic modeling software and computer aided drafting software.

ROAD DESIGN

Road design is the process of design of efficient and safe highways and roads.  This process consists of technical design considerations balanced by environmental, regulatory and safety considerations.  The technical considerations include grade, surface texture and sight distance of horizontal bends and vertical slopes in relation to the designed speed.  Structurally, a road design must ensure that the road is strong enough for the expected number of vehicles over time.

GRADING PLANS

Grading plans are created for building sites, roads, parking lots, ponds and other construction where large amounts of soil will be moved.  A typical grading plan will address both the reuqirements of site preparation and construction as well as temporary erosion control including the prevention of sedimentation or damage to off-site property.

SANITARY SEWER DESIGN

Sanitary sewer design encompasses all aspects of wastewater holding and transport systems.  The systems consist of pumps, pipes, storage tanks and various other parts such as valves, connections, manholes, and cleanouts.  The basic principals of hydraulics are applied together with the knowledge of the specific properties and behavior of these system components to develop an integrated sanitary sewer system that meets both aesthetic and regulatory requirements. 

STORM DRAINAGE PLANS

Storm drainage plans attempt to redirect excess water to a lower area such as a drainage ditch, dry well or catch basin.  Property development typically creates additional impermeable surfaces such as roofs, roads and parking lots that do not absorb water.  The proper handling of this increased surface water requires detailed analysis and may determine the use of ditches, swales, catchment ponds, storm drains or other site modifications to be successful.

WATER SYSTEM DESIGN

Water system design includes determining water sources and systems to handle, treat and distibute it.  This could include connections to a municiple water system, private or public well water systems, booster pump stations, water storage and treatment facilities and water distribution systems with fire protection.
