Synthesize site reports with other documentation and analysis
Three-Phase Power
A type of alternating current required for heavy loads.
Lift Station
A lift station pumps wastewater from lower to higher elevations.
Mothballing Historic Buildings
A term used in historic preservation that designates certain areas to be repaired or restored at a later date, under a later contract.
Adaptive Reuse
A process of adapting old structures for purposes other than those initially intended, while retaining their historic features.
Preservation
Places a high premium on the retention of all historic fabric through conservation, maintenance, and repair. It respects a building’s continuum over time, through successive occupancies, as well as the respectful changes and alterations that have been made.
Rehabilitation
Emphasizes the retention and repair of historic materials, but more latitude is given for replacement because it is assumed the property has deteriorated.
Restoration
Focuses on the retention of materials from the most significant time in a property’s history, while permitting the removal of materials from other periods.
Reconstruction
Establishes limited opportunities to re-create a non-surviving site, landscape, building, structure, or object with all new materials.
Benchmark
A benchmark is a point of known elevation on a survey occurring within or adjacent to the project site. All site elevations are taken based on this point.
Culvert
A drainage structure that runs under a road or portion of land and transports water.
Invert Elevation
The elevation of the lowest point of the pipe at a given location in reference to a benchmark.
Soil Resistivity Test
The measure of the volume of soil to determine its conductivity.
Proctor Compaction Test
Method to determine optimal moisture content of soil at which it will be most dense and achieve maximum dry density.
Contour Interval
This is the elevation difference between adjacent contour lines. This interval is used to show the general shape of the terrain.
Growth Boundary
A line on a map agreed upon by a city and county, a village and county, or a village and township, within which there is enough land to accommodate urban expansion, typically for up to 20 years. Urban services, like public sewer and water lines, agree not to extend beyond this boundary.
Impact = PAT
Impact = Population x Affluence x Technology. It is a formula for illustrating the impact on the environment of people and their lifestyles.
