A mousepad sent to us from the District of Columbia Association of Land Surveyors.
Rewritten here for easier reading:
"DC's 'Surveying Commandments'
Survey the Boundary RIGHT!
-- Do it the 'DC Way' --
I - Use boundary data from DC Surveyors Office ONLY.
II - Survey each Square as an "ISLAND", alone unto itself.
III - Set up the STREET LINES - set up the STREET LINES!
IV - Reestablish DC's PARALLEL OFFSET LINES in the field.
V - Work from BUILDING CALLS and other DCSO points that check.
VI - Use 'SURVEY BUILDINGS' and o ther ORIGINAL MONUMENTS as highest evidence.
VII - Hold DCSO's OBSERVED ANGLES over most distances.
VIII - PRORATE per District law, between verified monuments within subdivided Squares.
IX - Remember - 'Record' bearings & distances seldom match actual 'MEASURED' property lines in the field.
X - Be alert to EXCEPTIONS. They can sink your project!
And always observe the "ELEVENTH COMMANDMENT"... When in doubt, ask the DC SURVEYOR'S OFFICE.
NOTE - A DC License is required to practice land surveying and establish property lines in the District of Columbia.
