Survey Tracker Provides Visual Way to Follow Progress
October 12, 2012
Survey Tracker is a tool that allows you to visually follow the progress of the 1st Avenue East Improvement Project. Often times the design process seems like a prolonged period of time where limited information is made public. That's because it takes several months to gather survey data and other information that is critical to the overall project. The survey process alone takes several months to complete.
Survey tracker illustrates the areas where survey crews have completed their work (highlighted in blue). Please note that the majority of survey work already completed is within the city owned right-of-way. Additional work will continue on adjacent properties who have provided written authorization to survey.
What is the purpose of a Topographic Survey?
Topographic surveys are usually carried out in order to have an accurate record of the existing conditions of a parcel of land that is about to undergo some type of construction activity. It identifies elevations, trees, buildings streets, walkways, manholes, utility poles, retaining walls, etc...From this information, a three-dimensional electronic map is prepared. Since the purpose of this survey is to serve as a base map for the design of a road and associated improvements, it is also necessary to delineate perimeter boundary lines and existing easements on or crossing the property being surveyed.
Design Engineers use a topographic survey as the beginning surface of their design and then plan what the proposed final surface will be like. In order to complete the survey, a land surveyor walks the entire project area taking shots (horizontal location and elevation) at a specific interval in order to meet the project accuracy requirements.
