HIGHWAY BOUNDARY CONCEPTS Part 1 - Center Line Recovery Slide 2
Introduction Recovery of the Existing Right of Way Center Line is
needed on every project Recovery of the Existing Right of Way
Center Line is needed on every project The existing right of way is
dependent on the location of the existing center line. The existing
right of way is dependent on the location of the existing center
line. When no new right of way is needed: When no new right of way
is needed: You need to know what are your limits. When new right of
way is to be acquired: When new right of way is to be acquired: You
want to know how much land is acquired. Slide 3 The Primary Element
of the Highway is the Tangent The purpose of the highway is to
provide a transportation route. The purpose of the highway is to
provide a transportation route. Considerations: Considerations:

each of these, the tangent is preferred. Slide 4 Slide 5 Boundary
Control and Legal Principles Boundary Control and Legal Principles
- Curtis M. Brown - Curtis M. Brown Order of importance for
conflicting elements of land location Order of importance for
conflicting elements of land location A. Right of possession
(unwritten conveyance) B. Senior right (in the event of an overlap)
C. Written intentions of Parties 1. Call for a survey 2. Call for
monuments a. Natural b. Artificial 3. Direction and Distance 4.
Direction or Distance 5. Area 6. Coordinates Slide 6 That which is
the most obvious is of higher importance. That which is the most
obvious is of higher importance. Monuments over distances Monuments
over distances Distances over bearings Distances over bearings
Bearings over areas Bearings over areas Tangents being less complex
than curves, have higher importance. Tangents being less complex
than curves, have higher importance. If there is a conflict between
tangents and curves, tangents should prevail. If there is a
conflict between tangents and curves, tangents should prevail.
Curve definitions yield to the resolved tangents. Curve definitions

Today's Project Today's Project Monuments are an aid to recover the
existing center line. Monuments are an aid to recover the existing
center line. Slide 31 30 Slide 32 ODOT Monuments are a Reference to
the Center Line Do not try to connect the dots. Do not try to
connect the dots. You will not end up with a straight line. Slide
33 Slide 34 The Center Line is a Mathematical Model It is not an
exact match. It is not an exact match. but but Slide 35 Where we
had a single tangent, we should recover a single tangent Slide 36
Curves should be tangent to the tangents Semi Tangent has the same
bearing as the tangent Slide 37 Spirals should be brought forward
Slide 38 Other elements of the center line model Station equations
are perpetuated. Station equations are perpetuated. If angle points
existed, they are perpetuated. If angle points existed, they are
perpetuated. Offsets from two or more different center lines are
maintained. Offsets from two or more different center lines are
maintained. Slide 39 Monuments Control the Tangents Searching for
monuments. Searching for monuments. Presume the right of way is
fully monumented Presume the right of way is fully monumented
Search every PC, PS, PSC, PCS and PT Search every PC, PS, PSC, PCS
and PT Search for any PI that falls in the right of way Search for
any PI that falls in the right of way Search the 500 and 1000 foot
stations Search the 500 and 1000 foot stations Decide which
monuments to use. Decide which monuments to use. Preference is

Slide 44 Slide 45 Tangents Control the Curves The tangent is the
primary element of the highway. The tangent is the primary element
of the highway. Curves connect the tangents together. Curves
connect the tangents together. Slide 46 Slight change in delta
angle Slide 47 More common a simple curve Slide 48 Or a curve with
spirals Slide 49 Establishing the tangents, forces the definition
for two key elements of any curve: Establishing the tangents,
forces the definition for two key elements of any curve: The
location of the PI. The location of the PI. And the delta angle.
And the delta angle. You can either use the You can either use the
Record degree of curve with a different semi- tangent distance.
Record degree of curve with a different semi- tangent distance.or
Use the record semi-tangent distance with a different degree of
curve. Use the record semi-tangent distance with a different degree
of curve. Slide 50 If the curve contains spirals, there is no need
to prorate the curve and the spirals. If the curve contains
spirals, there is no need to prorate the curve and the spirals.
Maintain the record length of the spiral. Maintain the record

project. Only the right of way on one side of the highway may be
affected by a past project. More than one center line may need to
