STANDARD COGO PROCEDURES
REVISED 5/1/95
1 NEW DRAWING
1.1 Start a new AutoCad/COGO drawing using the CGPROTO.DWG prototype
drawing found in
F:\GROUPS\PARKS\CGPARCEL
1.2 File the new drawing under the park ID number plus "CG"
1.2.1 Example: SOOOO1CG.dwg for Addison Blockhouse S.H.S.
1.2.2 All park drawings shall be filed in
F:\GROUPS\PARKS\CGPARCEL
1.3 Attach, as an Xref, the USGS quad(s), if available.
1.3.1 All USGS quads may be found in
F:\GROUPS\PARKS\QUADS
1.3.2 The USGS quads are for reference only and shall not be
modified.
2 SOURCES FOR BOUNDARY DEVELOPMENT
2.1 Electronic survey file: Parcel deeds from 1991 to present may
have an electronic survey file. Research should be done to locate any
electronic files from Survey and. Mapping. The electronic survey files need
to be verified per our deeds to be certain all out easements and out parcels
are represented. Also, one survey may encompass several deeds and will need to
be broken out deed per deed.
2.2 Deed descriptions : The parcel boundaries will be generated
from the legal descriptions on the deeds.
2.3 USGS 1-24,000 electronic quads: Certain information on the
electronic quads (section lines, water meander lines and roadways) may be used
if and only if better information, such as bearing and distance calls and
electronic survey information, is not available
2.4 USGS 1-24,000 paper quads: Hardcopies of USGS quadrangle maps
compliment the electronic quads and provide a good visual reference. In
addition, if the electronic quad is not available, section lines, water meander
lines and roadways may be digitized from the paper quads as a last resort.
2.5 TRW/REDI tax maps: Tax maps are available for some counties
and provide information on tax parcels, government lots and roadways.
2.6 Additional sources:
2.6.1 Government survey plats show government lot boundaries.
2.6.2 Water line surveys are available for some coastal water
lines and river meander lines.
2.6.3 Base maps for the parks may help to clarify confusing
boundaries but are to be used for visual reference only
3 OBTAINING SOURCE INFORMATION
3.1 Electronic quads : If the quad(s) you need is/are not on the QUAD
directory, notify Kelley in writing requesting the specific quad(s) by quad
number.
3.1.1 The quad number (s) for each park may be determined as
follows:
1) find the general park location using THE FLORIDA STATE PARK
SYSTEM map,
2) from the GMDNCC FLORIDA BASEMAP, select the USGS
Quadrangle(s) corresponding to the paper quadrangle(s) in the COGO folder for
that park,
3) each quad has a four (4) digit number followed by
the letter "N", "W", or "E" associated with north, west and east zones,
respectfully -- choose the zone which applies to all or most of the previously
selected quad(s),
4) record the quad number (s) on parks COGO folder and
COGO Boundary Development Sheet.
3.1.2 Record the request in your COGO notebook
3.2 Electronic survey: If you need an electronic survey file, notify
Kayle in writing. Include the park name, county, Section, Township and Range,
deed date, grantor and any other information you feel may be helpful.
3.2.1 Record the request in your COGO notebook.
3.3 TRW/REED tax maps: Copies of tax maps may be obtained by
notifying Todd in writing. Include the county, Section, Township and Range
with your request.
3.3.1 Record the request in your COGO notebook.
3.4 Deeds and official records: For deeds and other count records,
notify Todd in writing. Include the county, O.R. book and page numbers and any
other information you feel may be helpful. Make absolutely certain that the
parcel boundaries cannot be completed without this information before you
request it.
3.4.1 Record the request in your COGO notebook.
3.5 Additional information: Should you require any other resources
such as government survey plats or water line surveys, notify Todd in writing.
Include the park name, county, Section, Township and Range and any other
information you feel may be helpful.
3.5.1 Record the request in your COGO notebook.
4 PARCEL BOUNDARY DEVELOPMENT For our purposes a parcel is defined as all that
area, upland or submerged, as described by a single deed.
4.1 From electronic survey: If an electronic survey is used, the
parcel boundary shall be WBLOCKed and INSERTed on the park drawing. For an
insertion point, use the POINT OF BEGINNING as specified on the electronic
survey.
4.2 From legal descriptions: Most parcel boundaries will be created
from the legal deed descriptions. These descriptions may provide bearing and
distance calls or refer to quadrangle sections, manmade or natural features,
government lots, tax parcels, or a combination thereof.
4.2.1 Bearing and distance calls are the most accurate of all
the deed information and shall be used whenever available, even for water
lines, section lines and roadways.
NOTE: If a bearing and a distance are provided but the
description also refers to a specific location (section line, roadway, water
line, etc.) and the location can be positively determined, follow the bearing
to the specified location regardless of the distance.
4.2.2 When it is necessary to use information from an
electronic quad, verify the entities needed for your parcel boundary then
duplicate them on your drawing file.
4.2.3. If REDI tax maps are used, dimensions may be scaled but
verify that the scale you are using is correct and that you can accurately
locate the parcel boundaries on the electronic quad(s). Also, parcel
information may be digitized as a last resort.
4.3. From other sources: Only as a last resort and in the absence of
more accurate information, other sources may be used to complete parcel
boundaries. However, the use of any sources not specified in this section
requires Todd's approval.
4.3.1. Also, record your request and Todd's decision in your
COGO notebook.
4.3.2. Todd will notify Kelley when other information is used.
5 DRAWING REQUIREMENTS
5.1 Parcel boundaries: The boundaries of each parcel shall meet the
following requirements.
5.1.1 All parcel boundaries shall be on the B-PARCEL layer.
5.1.2. Individual parcel boundaries should close but do not
need to be polylines.
5.1.3 All temporary lines used to create parcel boundaries
should be removed.
5.1.4. Parcels should not overlap. Notify Todd if this occurs.
5.1.5. When two parcels touch along one or more sides, only
one (1) dividing line is necessary. Double lines should be avoided.
5.2 Parcel numbers: Each parcel shall be given a nine (9) digit
identification number (####-#####) as follows.
5.2.1 The first four (4) digits correspond to the Unit I.D.
Number for the park being developed.
5.2.2 The last five (5) digits are used to sequentially number
the parcels in chronological order according to deed date where "-00001" refers
to the oldest deed. NOTE: If a parcel is added later, chose the next
available number regardless of deed date and do not renumber the parcels.
5.2.3 Clearly label each parcel on the drawing with its
complete parcel number.
5.2.4 All parcel number labels and associated leader lines
shall be on the B-PARTXT layer.
5.2.5 Record each parcel number, grantor and deed date on the
park's PARCEL IDENTIFICATION SHEET.
5.2.6 If a lease exists without a deed, use the lessor and
lease date in place of the grantor and deed date and note it on the park's
PARCEL IDENTIFICATION SHEET.
5.2.7 Example: "0001-00001" would represent the parcel
described in the oldest deed for Addison Blockhouse S.H.S.
5.3 Out parcels: Out parcels are areas removed from a parcel
according to the legal description and should have their own respective
boundaries.
5.3.1 All out parcel boundaries shall be on the B-OUTL layer.
5.3.2 In addition to its own boundary, each out parcel shall
have a parcel boundary on the B-PARCEL layer and a park boundary on the B-BNDL
layer.
5.3.3 Clearly label all out parcels with the word "OUT".
5.3.4 All "OUT" labels and associated leader lines shall be
on the B-OUTTXT layer/
5.3.5 Out parcels will not be recorded on the PARCEL
IDENTIFICATION SHEET.
5.4 Park boundary: After all the parcel boundaries have been
completed, create a separate polyline boundary for the entire park.
5.4.1 If the park consists of several non-adjoining pieces,
each piece should have its own separate polyline boundary.
5.4.2 All boundary lines shall be on the B-BNDL layer.
