EXECUTIVE SUMMARY
Recommendation to amend Exhibit “A” to Resolution No. 2013-238, as amended, the list of Speed
Limits on County Maintained Roads, to reflect speed limit changes at six separate locations.
(Estimated Fiscal Impact: $1,000, Transportation Operating Fund 101)
OBJECTIVE: To revise the speed limit on portions of Celeste Drive, CR 29 (Collier Avenue/Broadway
Avenue E /Copeland Avenue S), Goodland Bay Drive, Lely Island Boulevard, and San Marco Road and
amend the list of Speed Limits on County Maintained Roads.
CONSIDERATIONS: Traffic Operations reviewed the current list of speed limits and recommends the
following changes:
1. Reduce the existing speed limit on Celeste Drive, in Lely Resort, from 35 mph to 30 mph.
2. The engineering study determined that various speed limits should be implemented along County Road
29 (Collier Avenue/ Broadway Avenue E/ Copeland Avenue S) near Everglades City:
Name From To Limit
CR 29 US 41 900’ north of Dupont St 55 mph
Collier Ave 900’ north of Dupont St 350’ north of Riverview Dr 45 mph
Collier Ave 350’ north of Riverview Dr 100’ north of Gardenia St S 35 mph
Collier Ave 100’ north of Gardenia St S Broadway Ave E 25 mph
Broadway Ave E Collier Ave Traffic Circle 25 mph
Copeland Ave S Traffic Circle 500’ north of Jasmine St W 25 mph
Copeland Ave S 500’ north of Jasmine St W 200’ south of Plantation Pkwy 35 mph
Copeland Ave S 200’ south of Plantation
Pkwy
1,000’ north of N Lopez Ln 45 mph
Copeland Ave S 1,000’ north of N Lopez Ln End 30 mph
3. The engineering study recommendation determined that 25 mph is an appropriate speed limit for
Goodland Bay Drive northeast of the Immokalee Road/Collier Boulevard intersection.
4. The engineering study determined that 25 mph is an appropriate speed limit for Lely Island Boulevard
within Lely Resort.
5. Various speed limits should be implemented along San Marco Road connecting US41 to Marco Island:
From To Limit
US 41 west of US 41 approximately 1600’ 45 mph
west of US 41 approximately 1600’ approximately 5.5 miles west of US 41 55 mph
approximately 5.5 miles west of US 41 approximately 300’ west of Goodland Dr 45 mph
6. As the construction relating to the Gator Canal Bridge Replacement (Project Number 66066) is
complete, removal of a temporary decrease in the speed limit on Immokalee Road (CR 846) beginning
approximately 2.25 miles east of Oil Well Grade Road and extending east approximately 1500 feet is
required. The speed limit in this area is 55 mph.
The Sheriff’s Office was contacted regarding changing the speed limits and concurs with the
recommendations of Traffic Engineering staff.
Pursuant to Florida Statute, Chapter 316, Collier County Ordinance No. 91-25, as amended, and
16.A.17
Packet Pg. 796
05/24/2022
Resolution Number 2013-239, as amended, the Board has the authority to establish and alter speed limits
by means of a resolution filed with the Clerk that creates a single comprehensive codification of all speed
limits on county-maintained roads. The Board may set speed zones where a change is reasonable and in
conformity with criteria promulgated by the Florida Department of Transportation (FDOT). The criteria
for work zones must include consideration of existing and anticipated field conditions and is defined in
the “Speed Zoning for Highways, Roads and Streets in Florida” manual (FDOT Manual Number 750-
010-002, 1997 Edition). This manual was developed by the FDOT to promote uniformity in the
establishment of state, municipal and county speed zones throughout the State of Florida.
FISCAL IMPACT: Funding required for staff to replace the speed limit signs on the respective streets is
estimated at $1,000. Funding is available in Transportation Operating Fund 101, Traffic Operations Cost
Center 163630.
GROWTH MANAGEMENT IMPACT: This action will result in no growth management impact.
LEGAL CONSIDERATIONS: This item has been reviewed by the County Attorney, is approved as to
form and legality and requires majority vote for approval. -JAK
RECOMMENDATION: To approve the attached Resolution amending Exhibit “A” to Resol ution
2013-239, to change the speed limits on portions of Celeste Drive, County Road 29 (Collier
Avenue/Broadway Avenue E/Copeland Avenue S), Goodland Bay Drive, Lely Island Boulevard, San
Marco Road, and Immokalee Road.

Synopsis
Date Project Name:
December 17, 2021 Speed Limit Study – Individual Roadways
The Traffic Operations Section of the Collier County’s Growth Management Division conducted
an engineering and traffic investigation study based upon the Manual on Uniform Traffic Control
Devices (MUTCD) to determine if standard speed limits on county roadways due to statutory
constraints or within Residential Districts is appropriate.
The MUTCD, published by the U.S. Department of Transportation is the national standard for traffic
control devices. The Florida Department of Transportation has adopted the MUTCD as the State
standard, and it governs the placement and design of traffic signals, signs, and pavement markings on
public and private roads within the state.
Additionally, the Florida Department of Transportation (FDOT) provides guidance for
establishing a speed zone in the following manual: Topic No. 750-010-002, Rule 14-15.012,
F.A.C. “Speed Zoning for Highways, Roads and Streets in Florida”, March 1997, Revised;
August 2018.
This study conforms with the criteria promulgated by the Florida Department of Transportation (FDOT) and
Florida Statute, Section 316, specifically:
316.189 Establishment of municipal and county speed zones.—
(2) SPEED ON COUNTY ROADS.—The maximum speed on any county-maintained road is:
(a) In any business or residence district, 30 miles per hour in the daytime or nighttime;
provided that with respect to residence districts a county may set a maximum speed limit of 25
miles per hour after an investigation determines that such a limit is reasonable; and it shall
not be necessary to conduct a separate investigation in each residence district.
(b) On any other part of a county road not a business or residence district, as set forth in s.
316.183.
316.183 Unlawful speed.—
(1) No person shall drive a vehicle on a highway at a speed greater than is reasonable and
prudent under the conditions and having regard to the actual and potential hazards then
existing. In every event, speed shall be controlled as may be necessary to avoid colliding with

any person, vehicle, or other conveyance or object on or entering the highway in compliance
with legal requirements and the duty of all persons to use due care.
(2) On all streets or highways, the maximum speed limits for all vehicles must be 30 miles
per hour in business or residence districts, and 55 miles per hour at any time at all other
locations. However, with respect to a residence district, a county or municipality may set a
maximum speed limit of 20 or 25 miles per hour on local streets and highways after an
investigation determines that such a limit is reasonable. It is not necessary to conduct a
separate investigation for each residence district.
(4) The driver of every vehicle shall, consistent with the requirements of subsection (1), drive
at an appropriately reduced speed when:
(d) Traveling upon any narrow or winding roadway; and
(e) Any special hazard exists with respect to pedestrians or other traffic or by reason of
weather or highway conditions.
The Board of County Commissioners(BCC) may set speed zones altering such speeds, both as to
maximum and minimum, after investigation determines such a change is reasonable and in conformity to
criteria promulgated by the Department of Transportation, except that no such speed zone shall permit a
speed of more than 60 miles per hour.
In addition, the Collier County Land Development Code Section 110-122. – Definitions:
(5) Arterial Roadway shall mean any street or roadway that constitutes the highest degree of
mobility at the highest speed, for long, uninterrupted travel, and constitutes the largest
proportion of total travel as per the Federal Functional Classification Map maintained by the
State of Florida Department of Transportation District Office, as amended, and is owned by
the County.
(7) Collector Roadway shall mean any street or roadway that provides a mix of mobility and
land access functions, linking major land uses to each other or to the arterial highway system
as per the Federal Functional Classification Map maintained by the State of Florida
Department of Transportation District Office, as amended, and is owned by the County.
(19) Local Roadways shall mean any street or roadway which primarily serves to provide
access to adjacent land and service to travel over relatively short distances as compared to
Collector Roadways or Arterial Roadways, as per the Federal Functional Classification Map
maintained by the State of Florida Department of Transportation District Office, as amended.
BACKGROUND
The Traffic Operations Section of the Collier County Growth Management Division conducted an
engineering study and traffic investigation study to determine the appropriate speed limit for Celeste Dr
in which the segment runs within the Lely Resorts community.
The primary purpose in the establishment of a speed zone is to determine the appropriate speed of the
roadway segment that notifies the driver of the maximum operating speed that is considered
16.A.17.b

reasonably safe in optimum weather and visibility conditions. It is intended to establish the speed limit
which a normally prudent driver can perceive and react safely.
The establishment, including any alteration and posting of speed limits on county streets and highways,
as set forth in Section 316.189, Florida Statutes (F. S.), must be based on an engineering study and traffic
investigation that determines such a posting is reasonable and in conformity to criteria promulgated by
the Florida Department of Transportation (FDOT) and the Florida Statute.
EXISTING ROAD CHARACTERISTICS
This segment is County maintained, two-lane, non-median separated rural roadways without bike lanes
on either side of the road. This segment is functionally classified as local roadways. The existing posted
speed limit is 25 MPH.
REPORTED CRASH HISTORY
The length of the segment of the Celeste Dr corridor is approximately 1.7 mile.
There was a total of 3 reported crashes from 2017 through March of 2021. There were Zero (0)
reported crashes involving pedestrians or bicyclists. There were zero (0) fatalities noted for this period.
Yearly summation of the segment’s reported crashes for this time period are: 2021 (March) - 0 crashes,
2020 - 1 crashes, 2019 - 1 crash, 2018 - 0 crashes, 2017 - 1 crash. Distribution of the reported crashes
generally correlated as “rear end” crashes 1 events, 1 were noted as “angle” and 2 were noted
aggressive driving” as a contributing factor.
SPEED INVESTIGATION
Florida Statutes require that the change of speed zone values as outlined in Sections 316.183 and
316.189 F.S. be based on an engineering study and traffic investigation. The investigation is to include,
but is not limited to, the measurements of prevailing speeds and other traffic engineering evaluations
contained in the "2018 FDOT Design Manual” that was adopted by FDOT’s Roadway Design Bulletin 17-
12.
Additionally, consideration was given to the “Speed Zoning for Highways, Roads and Streets in Florida"
manual (FDOT Topic Number 750-010-002, July 2017 edition), which was developed by the FDOT to
promote uniformity in the establishment of state, municipal, and county speed zones throughout the
State of Florida.
Two primary types of data were analyzed in determining the prevailing speed: 85th percentile speed, the
speed which 85% of the motorists drive at or below and the upper limit of the 10-mph pace, the 10-mph
range that most people drive, the reasoning behind the foregoing investigations is that the majority of
drivers travel at a reasonably safe speed for the various roadway conditions encountered, and that these
investigations help determine what may be reasonable speed limits. A speed study on Celeste Dr was
conducted the 21st of October 2020. The following data was collected:

ANALYSIS:
The FDOT Design Manual, Chapter 201.4 – Table 201.4.1 has listed the speed range of this C5 Urban Center
roadway classification as between 25 mph & 35 mph.
Speed data was analyzed in determining the prevailing speed: 85th and the upper limit of the 10-mph pace.
Additionally, staff investigations determined that authority was granted that allows counties and
municipalities to study contiguous neighborhoods and establish a uniform speed limit for geographically
specific locations that have similar characteristics. These road segments are within the Lely Resorts
neighborhood which is considered a residential district and evaluated for compliance with statue section
316.183.
This roadway segment has a nonlinear geometric configuration with a roundabout and multiple access
points to various housing developments.
To keep consistent with the neighborhood and avoid potential confusion, the investigation determined that it
would be reasonable to post the identified roadways with a statutory Speed Limit at 30 MPH.
A primary benefit of this investigation and subsequent speed limit changes, is to assist motorists that are
unfamiliar with the area to have a uniform speed limit based on the surrounding roadway conditions.
RECOMMENDATIONS:
Based on the FDOT’s guidelines, roadway design speed, crash frequency/causative factors,

January 10, 2022 Speed Limit Study – Individual Roadways
The Traffic Operations Section of the Collier County’s Growth Management Division conducted
an engineering and traffic investigation study based upon the Manual on Uniform Traffic Control
Devices (MUTCD) to determine if standard speed limits on county roadways due to statutory
constraints or within Residential Districts is appropriate.
The MUTCD, published by the U.S. Department of Transportation is the national standard for traffic
control devices. The Florida Department of Transportation has adopted the MUTCD as the State
standard, and it governs the placement and design of traffic signals, signs, and pavement markings on
public and private roads within the state.
Additionally, the Florida Department of Transportation (FDOT) provides guidance for
establishing a speed zone in the following manual: Topic No. 750-010-002, Rule 14-15.012,
F.A.C. “Speed Zoning for Highways, Roads and Streets in Florida”, March 1997, Revised;
August 2018.
This study conforms with the criteria promulgated by the Florida Department of Transportation (FDOT) and
Florida Statute, Section 316, specifically:
316.189 Establishment of municipal and county speed zones.—
(2) SPEED ON COUNTY ROADS.—The maximum speed on any county-maintained road is:
(a) In any business or residence district, 30 miles per hour in the daytime or nighttime;
provided that with respect to residence districts a county may set a maximum speed limit of 25
miles per hour after an investigation determines that such a limit is reasonable; and it shall
not be necessary to conduct a separate investigation in each residence district.
(b) On any other part of a county road not a business or residence district, as set forth in s.
316.183.
316.183 Unlawful speed.—
(1) No person shall drive a vehicle on a highway at a speed greater than is reasonable and
prudent under the conditions and having regard to the actual and potential hazards then
existing. In every event, speed shall be controlled as may be necessary to avoid colliding with

any person, vehicle, or other conveyance or object on or entering the highway in compliance
with legal requirements and the duty of all persons to use due care.
(2) On all streets or highways, the maximum speed limits for all vehicles must be 30 miles
per hour in business or residence districts, and 55 miles per hour at any time at all other
locations. However, with respect to a residence district, a county or municipality may set a
maximum speed limit of 20 or 25 miles per hour on local streets and highways after an
investigation determines that such a limit is reasonable. It is not necessary to conduct a
separate investigation for each residence district.
(4) The driver of every vehicle shall, consistent with the requirements of subsection (1), drive
at an appropriately reduced speed when:
(d) Traveling upon any narrow or winding roadway; and
(e) Any special hazard exists with respect to pedestrians or other traffic or by reason of
weather or highway conditions.
The Board of County Commissioners (BCC) may set speed zones altering such speeds, both as to
maximum and minimum, after investigation determines such a change is reasonable and in conformity to
criteria promulgated by the Department of Transportation, except that no such speed zone shall permit a
speed of more than 60 miles per hour.
In addition, the Collier County Land Development Code Section 110-122. – Definitions:
(5) Arterial Roadway shall mean any street or roadway that constitutes the highest degree of
mobility at the highest speed, for long, uninterrupted travel, and constitutes the largest
proportion of total travel as per the Federal Functional Classification Map maintained by the
State of Florida Department of Transportation District Office, as amended, and is owned by
the County.
(7) Collector Roadway shall mean any street or roadway that provides a mix of mobility and
land access functions, linking major land uses to each other or to the arterial highway system
as per the Federal Functional Classification Map maintained by the State of Florida
Department of Transportation District Office, as amended, and is owned by the County.
(19) Local Roadways shall mean any street or roadway which primarily serves to provide
access to adjacent land and service to travel over relatively short distances as compared to
Collector Roadways or Arterial Roadways, as per the Federal Functional Classification Map
maintained by the State of Florida Department of Transportation District Office, as amended.
BACKGROUND
The Traffic Operations Section of the Collier County Growth Management Division conducted
an engineering study and traffic investigation study to determine the appropriate speed limit for
CR 29.
The primary purpose in the establishment of a speed zone is to determine the appropriate speed
of the roadway segment that notifies the driver of the maximum operating speed that is
16.A.17.c
Packet Pg. 834 Attachment: Engineering Study - CR 29 10 January 2022 (22025 : Amend Exhibit "A" to Resolution No. 2013-238, as emended, the list of Speed
Engineering Study - CR 29 10 January 2022.docx
considered reasonably safe in optimum weather and visibility conditions. It is intended to
establish the speed limit which a normally prudent driver can perceive and react safely.
The establishment, including any alteration and posting of speed limits on county streets and
highways, as set forth in Section 316.189, Florida Statutes (F. S.), must be based on an
engineering study and traffic investigation that determines such a posting is reasonable and in
conformity to criteria promulgated by the Florida Department of Transportation (FDOT) and the
Florida Statute.
EXISTING ROAD CHARACTERISTICS
This segment is a County maintained, rural roadway that is comprised of both the Rural and
Rural Town context classifications. The entire segment is approximately 8.0 miles in length.
The geometric configuration is typically linear in design and is comprised of two-lane and four-
lane segments with and without medians. The roadway segments have three (3) different cross-
sections: curb and gutter, paved shoulders and no edge treatment.
The existing posted speed limit varies from 30 MPH to 55 MPH
REPORTED CRASH HISTORY
The length of the segment of the CR 29 corridor is approximately 8.0 mile.
There was a total of 33 reported crashes from 2016 through December of 2021. There was zero
(0) reported crashes involving pedestrians or bicyclists. There were zero (0) fatalities noted for
this period. Yearly summation of the segment’s reported crashes for this time period are: 2021 -
3 crashes, 2020 - 5 crashes, 2019 - 4 crashes, 2018 - 5 crashes, 2017 - 10 crashes and 2016 had 6
reported crashes. Distribution of the reported crashes generally correlated as “rear end” and
“age” was noted as a factor in 15 crashes, 3 were noted as “angle” and 13 were noted aggressive
driving” as a contributing factor.
SPEED INVESTIGATION
Florida Statutes require that the change of speed zone values as outlined in Sections 316.183 and
316.189 F.S. be based on an engineering study and traffic investigation. The investigation is to
include, but is not limited to, the measurements of prevailing speeds and other traffic engineering
evaluations contained in the "2018 FDOT Design Manual” that was adopted by FDOT’s
Roadway Design Bulletin 17-12.
Additionally, consideration was given to the “Speed Zoning for Highways, Roads and Streets in
Florida" manual (FDOT Topic Number 750-010-002, July 2017 edition), which was developed
by the FDOT to promote uniformity in the establishment of state, municipal, and county speed
zones throughout the State of Florida.
Two primary types of data were analyzed in determining the prevailing speed: 85th percentile
speed, the speed which 85% of the motorists drive at or below and the upper limit of the 10-mph
pace, the 10-mph range that most people drive, the reasoning behind the foregoing investigations
is that the majority of drivers travel at a reasonably safe speed for the various roadway conditions
encountered, and that these investigations help determine what may be reasonable speed limits.

ANALYSIS:
The FDOT Design Manual, Chapter 201.4 – Table 201.4.1 has listed the speed range of this C2 Rural
roadway classification as between 55 mph & 70 mph for the northern extent whereas the southern
segment would be classified as C2T Rural Town classification with an allowable range of 25 mph &
45 mph.
Speed data was analyzed in determining the prevailing speed: 85th and the upper limit of the 10-mph
pace.
Additionally, staff investigations determined that authority was granted that allows counties and
municipalities to study contiguous neighborhoods and establish a uniform speed limit for
geographically specific locations that have similar characteristics.
This roadway segment generally has a linear geometric configuration with a Rural and Rural Town
characteristics.
A primary benefit of this investigation and subsequent speed limit changes, is to assist motorists that
are unfamiliar with the area to have a uniform speed limit based on the surrounding roadway
conditions.
RECOMMENDATIONS:
Based on the FDOT’s guidelines, roadway design speed, crash frequency/causative factors,
geometric configuration of this roadway segment, additional field and technical observations
indicate that an increase in the posted speed limit is warranted.
Therefore, it is recommended to alter the posted speed limit following the FDOT speed zoning
guidelines and is appropriate.

EXISTING ROAD CHARACTERISTICS
This segment is County maintained; two-lane, non-median separated urban roadways without bike lanes
on either side of the road. This segment is functionally classified as local roadway. Currently the
roadway does not have a posted speed limit.
REPORTED CRASH HISTORY
The length of the segment of the Goodland Bay Dr corridor, is approximately 600 feet in length.
There was a total of 6 reported crashes from 2016 through November of 2021. There were zero
reported crashes involving pedestrians or bicyclists. There were no fatalities noted for this period.
Yearly summation of the segment’s reported crashes for this time period are: 2021 (November) – 0
crashes, 2020 - 1 crash, 2019 – 2 crashes, 2018 - 0 crashes, 2017 - 2 crashes and 1 in 2016. Distribution
of the reported crashes generally correlated as “rear end” crashes three (3) events, zero (0) were noted
as “angle” and three (3) noted “aggressive driving” as a contributing factor.

ANALYSIS:
The FDOT Design Manual, Chapter 201.4 – Table 201.4.1 has listed the speed range of this C5
Urban Center roadway classification as between 25 mph & 35 mph.
However, staff investigations determined that authority was granted that allows counties and
municipalities to study contiguous neighborhoods and establish a uniform speed limit for
geographically specific locations that have similar characteristics.
The pedestrian crossings, offset geometry of the intersection and congestion were all factors
considered in deviating from prevailing speed metrics.
To keep consistent with the neighborhood and avoid potential confusion, the investigation determined
that it would be reasonable to post Goodland Bay Dr. at 25 MPH.
A primary benefit of this investigation is to assist motorists that are unfamiliar with the area to have
a uniform speed limit based on the surrounding roadway conditions.
RECOMMENDATIONS:
Based on the FDOT’s guidelines, roadway design speed, crash frequency/causative factors,
geometric configuration of this roadway segment, additional field and technical observations
indicates that a posted speed limit of 25 mph is warranted.
Therefore, it is recommended that a posted speed limit of 25 MPH is appropriate and meets the
FDOT speed zoning guidelines.

evaluations contained in the "2018 FDOT Design Manual” that was adopted by FDOT’s
Roadway Design Bulletin 17-12.
Additionally, consideration was given to the “Speed Zoning for Highways, Roads and Streets in
Florida" manual (FDOT Topic Number 750-010-002, July 2017 edition), which was developed
by the FDOT to promote uniformity in the establishment of state, municipal, and county speed
zones throughout the State of Florida.
Two primary types of data were analyzed in determining the prevailing speed: 85th percentile
speed, the speed which 85% of the motorists drive at or below and the upper limit of the 10-mph
pace, the 10-mph range that most people drive, the reasoning behind the foregoing investigations
is that the majority of drivers travel at a reasonably safe speed for the various roadway conditions
encountered, and that these investigations help determine what may be reasonable speed limits.
A speed study on Lely Island Blvd was conducted the 15th of October 2020. The following data

Additionally, staff investigations determined that authority was granted that allows counties and
municipalities to study contiguous neighborhoods and establish a uniform speed limit for
geographically specific locations that have similar characteristics.
A primary benefit of this investigation and subsequent speed limit changes, is to assist motorists that
are unfamiliar with the area to have a uniform speed limit based on the surrounding roadway
conditions.
ANALYSIS:
The FDOT Design Manual, Chapter 201.4 – Table 201.4.1 has listed the speed range of this C5 Urban Center
roadway classification as between 25 mph & 35 mph.
Speed data was analyzed in determining the prevailing speed: 85th and the upper limit of the 10-mph pace.
To keep consistent with the neighborhood and avoid potential confusion, the investigation determined that it would
be reasonable to post the identified roadways with a statutory Speed Limit at 25 MPH.
A primary benefit of this investigation and subsequent speed limit changes, is to assist motorists that are
unfamiliar with the area to have a uniform speed limit based on the surrounding roadway conditions.
RECOMMENDATIONS:
Based on the FDOT’s guidelines, roadway design speed, crash frequency/causative factors,
geometric configuration of this roadway segment, additional field and technical observations
indicates that a posted speed limit to match the adjoining neighborhood is warranted.
Therefore, it is recommended to post the speed limit for the segment of Lely Island Blvd to 25-mph
following the FDOT speed zoning guidelines and is appropriate.

Synopsis
Date Project Name:
December 20, 2021 Speed Limit Study – Individual Roadways
The Traffic Operations Section of the Collier County’s Growth Management Division conducted
an engineering and traffic investigation study based upon the Manual on Uniform Traffic Control
Devices (MUTCD) to determine if standard speed limits on county roadways due to statutory
constraints or within Residential Districts is appropriate.
The MUTCD, published by the U.S. Department of Transportation is the national standard for traffic
control devices. The Florida Department of Transportation has adopted the MUTCD as the State
standard, and it governs the placement and design of traffic signals, signs, and pavement markings on
public and private roads within the state.
Additionally, the Florida Department of Transportation (FDOT) provides guidance for
establishing a speed zone in the following manual: Topic No. 750-010-002, Rule 14-15.012,
F.A.C. “Speed Zoning for Highways, Roads and Streets in Florida”, March 1997, Revised;
August 2018.
This study conforms with the criteria promulgated by the Florida Department of Transportation (FDOT) and
Florida Statute, Section 316, specifically:
316.189 Establishment of municipal and county speed zones.—
(2) SPEED ON COUNTY ROADS.—The maximum speed on any county-maintained road is:
(a) In any business or residence district, 30 miles per hour in the daytime or nighttime;
provided that with respect to residence districts a county may set a maximum speed limit of 25
miles per hour after an investigation determines that such a limit is reasonable; and it shall
not be necessary to conduct a separate investigation in each residence district.
(b) On any other part of a county road not a business or residence district, as set forth in s.
316.183.
316.183 Unlawful speed.—
(1) No person shall drive a vehicle on a highway at a speed greater than is reasonable and
prudent under the conditions and having regard to the actual and potential hazards then
existing. In every event, speed shall be controlled as may be necessary to avoid colliding with

any person, vehicle, or other conveyance or object on or entering the highway in compliance
with legal requirements and the duty of all persons to use due care.
(2) On all streets or highways, the maximum speed limits for all vehicles must be 30 miles
per hour in business or residence districts, and 55 miles per hour at any time at all other
locations. However, with respect to a residence district, a county or municipality may set a
maximum speed limit of 20 or 25 miles per hour on local streets and highways after an
investigation determines that such a limit is reasonable. It is not necessary to conduct a
separate investigation for each residence district.
(4) The driver of every vehicle shall, consistent with the requirements of subsection (1), drive
at an appropriately reduced speed when:
(d) Traveling upon any narrow or winding roadway; and
(e) Any special hazard exists with respect to pedestrians or other traffic or by reason of
weather or highway conditions.
The Board of County Commissioners(BCC) may set speed zones altering such speeds, both as to
maximum and minimum, after investigation determines such a change is reasonable and in conformity to
criteria promulgated by the Department of Transportation, except that no such speed zone shall permit a
speed of more than 60 miles per hour.
In addition, the Collier County Land Development Code Section 110-122. – Definitions:
(5) Arterial Roadway shall mean any street or roadway that constitutes the highest degree of
mobility at the highest speed, for long, uninterrupted travel, and constitutes the largest
proportion of total travel as per the Federal Functional Classification Map maintained by the
State of Florida Department of Transportation District Office, as amended, and is owned by
the County.
(7) Collector Roadway shall mean any street or roadway that provides a mix of mobility and
land access functions, linking major land uses to each other or to the arterial highway system
as per the Federal Functional Classification Map maintained by the State of Florida
Department of Transportation District Office, as amended, and is owned by the County.
(19) Local Roadways shall mean any street or roadway which primarily serves to provide
access to adjacent land and service to travel over relatively short distances as compared to
Collector Roadways or Arterial Roadways, as per the Federal Functional Classification Map
maintained by the State of Florida Department of Transportation District Office, as amended.
BACKGROUND
The Traffic Operations Section of the Collier County Growth Management Division conducted
an engineering study and traffic investigation study to determine the appropriate speed limit for
San Marco Rd.
The primary purpose in the establishment of a speed zone is to determine the appropriate speed
of the roadway segment that notifies the driver of the maximum operating speed that is
16.A.17.f
Packet Pg. 849 Attachment: Engineering Study - San Marco Rd 20 Dec 2021 (22025 : Amend Exhibit "A" to Resolution No. 2013-238, as emended, the list of
Engineering Study - San Marco Rd 20 Dec 2021.docx
considered reasonably safe in optimum weather and visibility conditions. It is intended to
establish the speed limit which a normally prudent driver can perceive and react safely.
The establishment, including any alteration and posting of speed limits on county streets and
highways, as set forth in Section 316.189, Florida Statutes (F. S.), must be based on an
engineering study and traffic investigation that determines such a posting is reasonable and in
conformity to criteria promulgated by the Florida Department of Transportation (FDOT) and the
Florida Statute.
EXISTING ROAD CHARACTERISTICS
This segment is a County maintained; two-lane, non-median separated rural roadways without
bike lanes on either side of the road. This segment is functionally classified as C2 roadway. The
existing posted speed limit is 45 MPH.
REPORTED CRASH HISTORY
The length of the segment of the San Marco Rd corridor is approximately 6.6 mile.
There was a total of 25 reported crashes from 2016 through November of 2021. There was (1)
reported crash involving pedestrians or bicyclists. There were three (3) fatalities noted for this
period. Yearly summation of the segment’s reported crashes for this time period are: 2021
(November) - 2 crashes, 2020 - 5 crashes, 2019 - 2 crashes, 2018 - 3 crashes, 2017 - 8 crashes
and 2016 had 5 reported crashes. Distribution of the reported crashes generally correlated as
“rear end” crashes 3 events, 1 were noted as “angle” and 7 were noted aggressive driving” as a
contributing factor.
SPEED INVESTIGATION
Florida Statutes require that the change of speed zone values as outlined in Sections 316.183 and
316.189 F.S. be based on an engineering study and traffic investigation. The investigation is to
include, but is not limited to, the measurements of prevailing speeds and other traffic engineering
evaluations contained in the "2018 FDOT Design Manual” that was adopted by FDOT’s
Roadway Design Bulletin 17-12.
Additionally, consideration was given to the “Speed Zoning for Highways, Roads and Streets in
Florida" manual (FDOT Topic Number 750-010-002, July 2017 edition), which was developed
by the FDOT to promote uniformity in the establishment of state, municipal, and county speed
zones throughout the State of Florida.
Two primary types of data were analyzed in determining the prevailing speed: 85th percentile
speed, the speed which 85% of the motorists drive at or below and the upper limit of the 10-mph
pace, the 10-mph range that most people drive, the reasoning behind the foregoing investigations
is that the majority of drivers travel at a reasonably safe speed for the various roadway conditions
encountered, and that these investigations help determine what may be reasonable speed limits.
A speed study on San Marco Rd was conducted the 21st of October 2020. The following data

ANALYSIS:
The FDOT Design Manual, Chapter 201.4 – Table 201.4.1 has listed the speed range of this C2 Rural
roadway classification as between 55 mph & 70 mph.
Speed data was analyzed in determining the prevailing speed: 85th and the upper limit of the 10-mph
pace.
Additionally, staff investigations determined that authority was granted that allows counties and
municipalities to study contiguous neighborhoods and establish a uniform speed limit for
geographically specific locations that have similar characteristics.
This roadway segment has primarily a linear geometric configuration with canals on both sides.
A primary benefit of this investigation and subsequent speed limit changes, is to assist motorists that
are unfamiliar with the area to have a uniform speed limit based on the surrounding roadway
conditions.
RECOMMENDATIONS:
Based on the FDOT’s guidelines, roadway design speed, crash frequency/causative factors,
geometric configuration of this roadway segment, additional field and technical observations
indicate that an increase in the posted speed limit is warranted.
Therefore, it is recommended to increase the 45-mph speed limit for a 5.5-mile segment of San
Marco Rd to 55-mph following the FDOT speed zoning guidelines and is appropriate.
