Staff Recommendation
The Community Works Department recommends approval of Petition 21-56 a submittal from
Red Shamrock 12, LLC, represented by Kevin Lane of Basin Surveying for a Preliminary Plan
for a 5-lot, Class 2, subdivision of a vacant 9.94-acre parcel located at 4109 E. Main Street in
Farmington with the following stipulations:
1. The final plat shall include a benchmark elevation referenced from City of Farmington
GPS monument, including Northing & Easting on one corner of surveyed Lot.
2. Construction drawings for all required infrastructure, including the required
improvements to Gila Street, shall be submitted for review to the City of Farmington
Engineering Division prior to submittal of a final plat.
3. The Final Plat shall show an access utility easement for sewer services going through
Lots 1 through 4 to get to the sewer main on the east side of lot 5.
4. Access to Gila Street from the property shall be realigned to avoid impact to single family
residences.
Discussion
Vice Chair Freeman asked if staff recommendation is to move the access point down along the
lot line through Lot 4 and 5.
Planning Manager Escobar stated that she would recommend that it be moved toward Main
Street so it lines up with the Walgreens driveway or curve the access. Planning Manager
Escobar stated that Lot 1 is bigger than Lot 2, with Lot 1 being proposed to be a convenient
store/gas station. Planning Manager Escobar stated that the Planning Division is leaving it to the
engineers and the applicant to find a solution.
Vice Chair Freeman asked Planning Manager Escobar if the motion would be to recommend
staff’s recommendations and the issue would be handled administratively.
Planning Manager Escobar stated no, the final plat will come back before the Commission.
Commissioner Waldroup asked why there couldn’t be an exit between Lots 4 and 5.
Planning Manager Escobar stated that the Fire Department does require two in and out
entrances for every development.
Commissioner Waldroup stated that another access point could be added to the east.
Commissioner Waldroup asked if the deceleration lane on Main Street would be an entrance
point.
Planning Manager Escobar stated that an access point to the east is a possibility and the
deceleration lane is a decision that the NMDOT will have to make.
Commissioner Brown asked if two driveways on Main Street was a possibility.
Planning Manager Escobar stated that would be up to NMDOT.
Vice Chair Freeman asked if the applicant would be responsible for upgrading Gila Street.
Planning Manager Escobar stated yes and it would be to the end of the property.
Chair Cardon asked where do Lots 2 and 3 have access.
Planning Manager Escobar stated that the applicant is not proposing to not have an access on
Main Street, but to move the existing driveway.
Chair Cardon asked if the petitioner or the petitioner’s representative were present.
Kevin Lane, Basin Surveying, 108 Llano Street, Aztec, NM.
Josh Skarsgard, via conference call, 8220 San Pedro, Albuquerque, NM.
Mr. Lane stated that he is flexible and that it is a matter of design and Basin Surveying is not
involved in the design of this project.
Mr. Skarsgard stated curb cuts on Gila Street and Main Street had a complicated selection
process; the locations for the curb cuts were selected based on traffic counts in conjunction with
NMDOT. Mr. Skarsgard stated the reason for moving the access on Gila Street to the east is to
accommodate traffic that would be turning left into the shopping center.
Commissioner Waldroup stated that the reason this access point is being brought up is due to
the access point possibly being an issue, due to lighting, to the residence located off of Gila
Street.
Mr. Skarsgard stated that he would happily work with the homeowner to secure a solution to the
light issue, possibly by paying to add a wall or adding landscaping.
Vice Chair Freeman stated that if the entrance point is moved 10-15 feet to the west that might
be enough to change the alignment.
Planning Manager Escobar stated that would be staff recommendation as well. Planning
Manager Escobar stated that Gila Street is a City street and perhaps a discussion with the City
Traffic Engineer could be set up to discuss the access.
Mr. Lane stated that on the plat the dotted lines represent the plated Iles Subdivision and the
two lines that are close together is a platted alley, not an entrance into Walgreens.
Vice Chair Freeman asked Mr. Skarsgard if he would be willing to include the conversation of
moving access as part of a motion being made for approval.
Mr. Skarsgard stated that he is happy to study the area, but the collaboration of the incoming
tenants, the State Engineer and NMDOT were the result of the curb cut locations. Mr. Skarsgard
stated that he will do his best to mediate any issues as a result of the curb cut locations.
Vice Chair Freeman asked Mr. Skarsgard if the resident had reached out to speak about the
proposed project.
Mr. Skarsgard stated no, he was not aware of this issue until yesterday.
Commissioner Waldroup asked Mr. Skarsgard if he has had discussions regarding Gila Street
with the City of Farmington Traffic Engineer, since Gila Street is a City street.
Mr. Skarsgard stated that he is aware that Gila Street is a City street; having done many
projects within the City he does plan to work with City staff and will try his best to meet the
needs of all parties involved. Mr. Skarsgard stated that he loves working with the community
and has put a lot of time and money into this project to build a great shopping center for
Farmington.
Commissioner Waldroup asked Planning Manager Escobar if the verbiage for the motion should
include the discussion between the petitioner and the City Engineers.
Planning Manager Escobar stated that Stipulation #4 could be reworded to “The applicant will
work with staff to find a solution regarding mitigation of the headlights on Gila Street.”
Motion
A motion was made by Commissioner Waldroup and seconded by Vice Chair Freeman to
APPROVE Petition No. PP 21-56 as recommended by staff, with the change to stipulation 4, the
applicant will work with staff to find a solution regarding mitigation of the headlights on Gila
Street. The motion carried unanimously 5-0.

GENERAL INFORMATION
The petitioner is requesting preliminary plan approval for the Perea Subdivision Replat
A, a proposed subdivision of a 4.77-acre parcel in an unincorporated area of San Juan
County. This is a Class 2 subdivision, with all six lots 0.795 acres in size.
The petitioner is submitting this as an exemption plat to San Juan County. Newly
created lots will be transferred to family members of the petitioner in accordance with
New Mexico Statute 47-6-2.L.9.
The subject property is located in Tier 2 of the City of Farmington’s Planning and Platting
Jurisdiction. Subdivisions in Tier 2 are subject to all of the regulations in Chapter 6 –
Subdivision Standards of the UDC except for the following:
The requirements of section 6.4, subdivision design standards, shall apply to all rural
residential subdivisions, with the following modifications.
6.5.2 Blocks. Block length shall not exceed 1,500 feet in rural residential subdivisions. In
blocks over 800 feet in length, accessways, as defined herein, may be required near the
center of the block and at the end of a cul-de-sac to facilitate pedestrian traffic
movement.
6.5.3 Streets and alleys.
A. Streets shall comply with the requirements of section 6.4.7; provided, however,
that streets Class 2 and 3 subdivisions shall have:
(1) All weather, gravel or crushed stone base;
(2) Road surfaces with not less than a double penetration chip seal surface; and
(3) Road surface width of not less than 24 feet; and
(4) Eight-foot shoulder on each side.
B. Minimum rights-of-way width shall be 50 feet; provided, however, that minimum
rights-of-way for all thoroughfares, as shown on the City of Farmington Major
Thoroughfare Plan, which cross or form a subdivision boundary, shall be in
accordance with the requirements of subsection 6.4.7J., geometric standards-
street design criteria.
6.5.4 Pedestrian, biking and multi-use facilities.
A. Sidewalks are not required on residential and collector streets that are wholly
contained within rural residential subdivisions. If sidewalks are provided or
required, they shall meet all regulations in section 6.4.8, pedestrian, biking and
multi-use facilities, and shall be constructed away from the roadway surface to
provide adequate safety for pedestrians.
B. Sidewalks are required on all collectors and arterials that will continue beyond the
rural residential subdivision(s) and are required to be constructed in accordance
with the requirements of section 6.4.7, streets and alleys. Sidewalks on these
streets shall comply with the requirements of section 6.4.8, pedestrian facilities.
C. Biking facilities are not required.
Tier 2 properties are within 3 miles of the City boundaries. Although no specific study for
potential annexation in this area has been conducted, it is reasonable to assume that
annexation is a possibility. It is important therefore to control development to prevent the
inheritance of problem areas. This is the purpose of the State assigned Planning and
Platting Jurisdiction (PP & J).
Both the 2002 Farmington Comprehensive Plan and the 2040 Comprehensive Plan
reflect concerns about development in fringe areas that do not provide adequate
infrastructure.

special flood Hazard; or where the basis has not been established, subsection 7.7.2H., powers
and duties, the following are required:
A. Residential construction. New construction and substantial improvement of any
residential structure shall have the lowest floor, including basement and all
mechanical equipment, elevated to one foot or more above the base flood elevation. A
registered professional engineer, or land surveyor shall submit a certification to the
floodplain administrator that the standard of this subsection, as proposed in

this requirement.)
1. B. Nonresidential construction. New construction and substantial improvements of
any commercial, industrial or other nonresidential structure shall have either the
lowest floor, including basement and all mechanical equipment, elevated to one foot
or more above the base flood elevation or, together with attendant utility and
sanitary facilities, be designed so if the base is below one foot above the base flood
elevation the structure is watertight with walls substantially impermeable to the
passage of water and with structural components having the capability of resisting
hydrostatic and hydrodynamic loads and effects of buoyancy. A registered
professional engineer shall develop or review structural design, specifications, and
plans for the construction and shall certify that the design and methods of
construction are in accordance with accepted standards of practice as outlined in
this subsection. A record of such certification, which includes the specific elevation,
in relation to mean sea level, to which such structures are flood-proofed, shall be
maintained by the floodplain administrator.
C. Enclosure. New construction and substantial improvements, with fully enclosed areas
below the lowest floor that are usable solely for parking of vehicles, building access or
storage in an area other than a basement and which are subject to flooding shall be
designed to automatically equalize hydrostatic flood forces on exterior walls by
allowing for the entry and exit of floodwaters. Designs for meeting this requirement
must either be certified by a registered professional engineer or meet or exceed the
following minimum criteria:
(1) A minimum of two openings having a total net area of not less than one square inch
for every square foot of enclosed area subject to flooding shall be provided.
(2) The bottom of all openings shall be no higher than one-foot above grade.

FHBM or FIRM) shall be installed using methods and practices which minimize flood
damage. For the purposes of this requirement, manufactured homes must be
elevated and anchored to resist flotation, collapse, or lateral movement. Methods of
anchoring may include, but are not limited to, use of over-the-top or frame ties to
ground anchors. This requirement is in addition to applicable state and local
anchoring requirements for resisting wind forces.
(2) Manufactured and mobile homes to be placed or substantially improved within Zones
A1-30, AH and AE (on the community's FIRM) on-sites, either:
a. Outside of a manufactured or mobile home park or subdivision;
b. In manufactured home or mobile park or subdivision completed on or after the
effective date of floodplain management regulations;
c. In an expansion to an existing manufactured or mobile home park or subdivision;
d. In an existing manufactured and mobile home park or subdivision on which a
manufactured or mobile home has incurred "substantial damage" as a result of a
flood; or
e. Be elevated on a permanent foundation so that the lowest floor of the
manufactured home, including all mechanical equipment, elevated to one (1) foot
or more above the base flood elevation and be securely anchored to an
adequately anchored foundation system to resist flotation, collapse, and lateral
movement.
Section 14.3.2 of the Municipal Code will be submitted for revisions at the same time.

SECTION 13.4
TRAFFIC IMPACT STUDIES
CITY OF FARMINGTON REQUIREMENTS
Figure 1: Traffic Impact Study Flow Chart
13.4.1 Traffic impact study (TIS). A TIS is a traffic study that determines the potential traffic
impacts of a proposed traffic generator (i.e. proposed development). A complete
analysis will include an estimation of future traffic with and without the proposed
generator, analysis of the traffic impacts, and recommended roadway improvements that
may be necessary to accommodate the expected traffic.
A. Purpose. This standard provides uniform guidelines for conducting traffic impact
studies for proposed development with access to a City street.
B. Applicability. The community works director or designee shall determine applicability
based on the following factors and considerations:
(1) The City of Farmington has develop a TIS system based on the New Mexico
Department of Transportation’s (NMDOT) New Mexico Access Management
Manual (NMAMM) Section 16, Chapter 6. The City’s TIS system is used to
determine the level of impact a proposed development has on an adjacent
street. These impacts may result from the need for access along a street or
because a proposed development is expected to increase traffic volumes on
that particular street. The general types of traffic analysis are listed below:
a. Site Threshold Assessment (STH) – a screening-level analysis to determine
if additional traffic analysis is required. Consists of a one-page worksheet
(STH Form).
b. Site Traffic Analysis (STA) – a focused traffic study to assess site-specific
impacts of a proposed development. Consists of an engineering evaluation
and the preparation of a traffic study report.
c. Traffic Impact Analysis (TIA) – a detailed impact analysis of all traffic
operations, access and safety impacts within the prescribed study area for
a proposed development. Consists of an engineering evaluation and the
preparation study report.
13.4.2 Site Threshold Assessment (STH). A STH shall be required for all developing or
redeveloping properties that directly or indirectly access a City of Farmington street. The
requirements for the STH are described in the following subsections.
Figure 2: STH Form
A. The STH should examine existing street volumes and trip generation estimates to
determine if additional traffic analysis is required. The City uses the NMAMM’s STH
form. The following information is needed to complete STH form:
(1) A detailed description and location of the proposed development
(2) Existing daily traffic volumes for the adjacent roadway
(3) Trip generation estimates for the proposed development
B. The findings on this STH Form (Figure 2) will determine which direction the applicant
should follow on the Figure 1 flowchart. From the results of the STH form, the
applicant or their engineer would either proceed to a STA, a TIA or submit the results
of the STH to the City Traffic Engineer or their designee for review.
C. Trip generation.
(1) The latest edition of the ITE Trip Generation Manual shall be used to identify
trip generation rates. In cases where Trip Generation does not include trip rates
for a specific land use category, includes only limited data; or, where local trip
rates have been shown to differ from the ITE rates, other rates may be used
with the approval of the city.
(2) A trip generation table shall be prepared showing proposed land use, trip rates,
and vehicle trips for daily and peak hour periods and appropriate traffic volume
adjustments, if applicable. Site traffic generation shall be shown for daily,
morning and evening peak hour periods. Adjustments made for "passer-by"
and "mixed-use" traffic volumes shall follow the methodology outlined in the
latest edition of the ITE Trip Generation Handbook. The "passer-by" traffic
volume discount for commercial centers shall not exceed 25 percent unless
approved by the city.
D. Trip distribution and assignment.
(1) Projected trip volume shall be distributed and added to the projected non-site
traffic on the roadways and intersection(s) in the study area. The specific
assumptions and data sources used in deriving trip distribution and assignment
shall be documented in the report.
(2) Future traffic volumes shall be estimated using information from transportation
models, or applying an annual growth rate to the base-line traffic volumes. The
future traffic volumes shall correlate to the project's specific timeframe. If the
annual growth rate method is used, the city must give prior approval to the
percentage used.
(3) In addition, any nearby proposed or approved development projects shall be
taken into consideration when forecasting future traffic volumes. The increase
in traffic from proposed and approved developments, the application of an
annual growth rate, or a combination of an annual growth rate and proposed
and approved developments, shall be used to forecast the future traffic
volumes.
(4) The site-generated traffic shall be assigned to the street network in the study
area based on the approved trip distribution percentages. The site traffic shall
be combined with the forecast traffic volumes to show the total traffic conditions
estimated at development completion. The total daily and peak period turning
movement volumes for each traffic study intersection is required. In addition,
the base-line volume with site-generated traffic added to the street network
must also be shown. This amount will represent site-specific traffic impacts on
existing conditions
E. Internal circulation.
(1) Parking lot/on-site traffic circulation shall be in conformance with standards of
practice as set forth by "Transportation and Land Development" (ITE, current
edition).
13.4.1 Site Traffic Analysis (STA). The requirements for a STA are described in the following
subsections. All STA’s shall be sealed and signed by a registered/licensed New Mexico
Professional Engineer.
A. When is a STA required?
(1) A STA is required when the results of a STH indicate that the proposed
development is expected to generate between 25 and 100 peak-hour total trips,
and the adjacent roadway currently has a daily traffic volume greater than an
average of 1,000 vehicles per day per lane (vpdpl).
B. When is a STA Complete?
(1) A STA is considered complete when a final traffic study report is signed and
sealed and signed by a registered/licensed New Mexico Professional Engineer,
and is submitted to the City Traffic Engineer or their designee for review.
Where the results of the STA indicate one of the following:
a. The results indicate that the levels of service for the proposed access
points and the adjacent intersections satisfy or are better than the
applicable LOS standards (Table 15.C-1) and the City Traffic Engineer
concurs with those findings, or
b. The results of the STA indicate that improvements are required at the
proposed access points and/or at the adjacent intersections, and a
mitigation plan has been developed and approved by the City Traffic
Engineer.
C. Requirements for a STA:
(1) Traffic Analysis Scoping Meeting. A scoping meeting should be held between
the permittee and the City Traffic Engineer, and any local jurisdiction that has
authority over the proposed development. The meeting should be held when a
preliminary site plan is available. It should be the responsibility of the permittee
to schedule and prepare for the meeting. Specific aspects of the traffic analysis
that should be discussed at the scoping meeting include:
a. the proposed land use types and the development phasing
b. the number, type, and location of access points;
c. the anticipated level of traffic analysis;
d. the anticipated level of safety analysis;
e. the study area limits;
f. the analysis years and peak periods;
g. the background traffic growth rate;
h. the trip generation methodology;
i. the basis for trip distribution;
j. other ongoing development activity;
k. pertinent programmed highway improvements;
l. the traffic operations analysis techniques (e.g., isolated intersections versus
signal systems);
m. the documentation requirements; and,
n. any special conditions that should be considered.
(2) STA Study Area: The STA study area should be defined at the traffic analysis
scoping meeting. The study area for analysis should be proposed by the
permittee and approved by the City Traffic Engineer in coordination with any
local jurisdiction representatives that have authority over the proposed
development. Guidelines for defining the study area for urban and rural
conditions follow. When both urban and rural conditions exist within the study
area, the guidelines for urban conditions should be used.
a. Urban Study Areas: The STA study area for developments located on
highways in Access Categories UPA, UMA and UCOL should include all
site access points plus the first adjacent major intersection in each direction
from the site.
b. Rural Study Areas: The STA study area for developments located on
highways in Access Categories RPA, RMA and RCOL should include all
site access points plus the first adjacent intersection in each direction from
the site expected to be used by development traffic to access the regional
highway system, if any. Rural developments along isolated roadway
segments, having no intersecting collector or higher classified roadways
within 5 miles in either direction, should have the study area defined as the
site access points.
(3) Safety Analysis: Three years of accident history should be reviewed for the
major study area intersections. Intersection collision diagrams should be
prepared showing the number of accidents, accident type, date and time of
each accident, and accident severity. The intersection accident rate per million
entering vehicles (acc/MEV) should be indicated on the collision diagram. The
safety analysis should include a field review of the site.
(4) Analysis Years: The analysis years to be evaluated for site traffic analyses
should be as follows:
a. Existing Year Conditions
b. Implementation Year without the Proposed Development
c. Implementation Year with the Proposed Development
(5) The existing year is defined as the year the existing condition traffic counts are
obtained. The implementation year should be defined as the calendar year that
the proposed development is expected to commence operation.
(6) Analysis Peak Periods: Traffic analysis should be performed for the AM peak
hour and the PM peak hour of a typical weekday, or for the design hour
associated with special traffic conditions provided by the City Traffic Engineer.
(7) Trip Generation: Trip generation estimates should be based on the type and
intensity of the proposed land use, and should include estimates of daily and
peak-hour travel. The ITE Trip Generation Manual (Sub-Section 9.F) should be
used when the proposed land use is reasonably consistent with the land use
categories and descriptions contained in the Trip Generation Manual. When the
land use categories of the Trip Generation Manual clearly do not apply or the
rates are not appropriate for a propose development, locally derived trip
generation rates should be used. Trip generation rates that are based on local
conditions should be developed according to the methodology described in the
Trip Generation Manual.
(8) Trip Distribution and Assignment: Trip distribution and assignment may be
performed using manual techniques or a computer model. The trip distribution
methodology should consider the area population, locations of similar land use,
and travel distances. Trips should be assigned to the major street system
based on logical routing patterns. The major street system includes streets
classified as collectors and above. Trips may be assigned to the local street
system when the local street provides direct access to the proposed
development. Refer to Section 7 for definitions of trip distribution and trip
assignment.
(9) Traffic Projections: Implementation year traffic projections should include
background traffic growth, trips generated by other known development
projects in the study area, and trips generated by the proposed development,
as appropriate. Other known developments should be considered built out or, if
a phased development, built out according to the phasing schedule. Other
known development projects within the study area should be included when:
a. A development existed but was inactive when the existing condition traffic
counts were collected, or
b. A development was under construction at the time the existing condition
traffic counts were collected, or
c. A development opened since the existing condition traffic counts were
collected, or
d. A development was issued an access permit by the City of Farmington
since the existing condition traffic counts were collected. (The City Traffic
Engineer should inform the applicant of this condition at the scoping
meeting.)
(10) Intersection Traffic Analysis: Signalized and unsignalized intersections should
be analyzed consistent with the current Highway Capacity Manual
methodologies. The analyses may be performed using the current versions of
the Highway Capacity Software, TeaPac, or other analysis packages approved
by the NMSHTD Traffic Technical Support Section.
(11) Measuring Impacts: The STA should include an impact assessment for the
intersections analyzed comparing implementation year conditions without and
with the proposed development. Impacts should be measured based on the
following comparisons:
a. Isolated intersection performance statistics by approach movement and for
the overall intersection.
b. Magnitude and percent change in traffic volume by intersection approach
movement.
(12) Graphics: The STA documentation should contain a vicinity map showing all
arterial and collector roadways within a reasonable influence area of the site, a
study area map denoting the intersections included in the analysis, and a site
plan that details the site access location(s) and internal circulation patterns. In
addition to proposed land use details, the site plan should include dimensions
to adjacent property boundaries and to adjacent access points along the site
frontage, and should indicate locations of access points along the frontage on
the opposite side of the roadway.
(13) Documentation: All required site traffic analyses should include documentation
in the form of a bound report. The STA documentation should discuss the
following:
a. Study Purpose;
b. Development description;
c. Study area land use description;
d. Existing roadway and traffic conditions;
e. Safety analysis (3-years);
f. Background traffic growth;
g. Trip generation, distribution and assignment;
h. Traffic projections;
i. Traffic analysis, including traffic signal warrants;
j. Impact assessment;
k. Proposed site circulation and parking plan;
l. Access design specifications;
m. Summary of deficiencies and proposed mitigation; and,
n. Appended materials.
13.4.2 Traffic Impact Analysis (TIA). The purpose of a TIA is to conduct a comprehensive
analysis of the transportation system that will provide access to proposed development
site, including proposed access points, to identify potential short-term and long-term
impacts on the roadway system. The requirements for a TIA are described in the
following subsections. All traffic impact analyses shall be sealed and signed by a
registered New Mexico Professional Engineer prior to the issuance of an access permit
by the department.
A. When is a TIA required? A TIA shall be conducted for each new development or
property redevelopment along a roadway when:
(1) The results of a STH indicate that the proposed development is expected to
generate 100 or more peak-hour trips; or
(2) The results of a STA indicate that expected levels of service will be below the
LOS standards in Table 15.C-1, and a mitigation plan cannot be resolved
between the City Traffic Engineer and the permittee to address identified
deficiencies.
B. When is a TIA Complete? A TIA is considered complete when a final traffic study
report, signed and sealed by a New Mexico registered professional engineer, is
submitted to the City Traffic Engineer or their designee, and
(1) The results of the TIA indicate that the levels of service for the proposed
access points and the study area intersections satisfy or are better than the
applicable LOS standards (Table 15.C-1) and the City Traffic Engineer or their
designee concurs with those findings, or
(2) The results of the TIA indicate that improvements are required at the proposed
access points and/or at the study area intersections, and a mitigation plan has
been developed and approved by the City Traffic Engineer or their designee.
C. Requirements for Conducting a TIA: The requirements for all traffic impact analyses
follow. Additional requirements may be imposed by the City Traffic Engineer on a
project-specific basis.
(1) Traffic Analysis Scoping Meeting: A scoping meeting should be held between
the permittee and the City Traffic Engineer, and any local jurisdiction that has
authority over the proposed development. The meeting should be held when a
preliminary site plan is available. It should be the responsibility of the permittee
to schedule and prepare for the scoping meeting. Specific aspects of the traffic
analysis that should be discussed at the scoping meeting include:
a. the proposed land use types and the development phasing;
b. the number, type, and location of access points;
c. the anticipated level of traffic analysis;
d. the anticipated level of safety analysis;
e. the study area limits;
f. the analysis years and peak periods;
g. the background traffic growth rate;
h. the trip generation methodology;
i. the basis for trip distribution;
j. other ongoing development activity;
k. pertinent programmed highway improvements;
l. the traffic operations analysis techniques (e.g., isolated intersections versus
signal systems);
m. the documentation requirements; and,
n. any special conditions that should be considered.
(2) TIA Study Area: The TIA study area should be defined based on the location
and complexity of the proposed development, and should progressively expand
with the complexity of proposed development. The TIA study area should be
defined at the traffic analysis scoping meeting. The study area should be
proposed by the permittee and approved by the City Traffic Engineer in
coordination with any local jurisdiction representatives that have authority over
the proposed development. Guidelines for defining the study area for urban
and rural conditions follow. When both urban and rural conditions exist within
the study area, the guidelines for urban conditions should be used.
a. Urban Study Areas: The TIA study area for developments located on
roadways in Access Categories UPA, UMA and UCOL should be
determined based on the following guidelines for urban conditions.
Typically, in urban areas, a TIA study area extending 1 mile from the
proposed development site should be sufficient.
1. The minimum urban study area size should include all site access
points, the off-site intersections where a developer may reasonably be
required to implement physical improvements, plus one additional
major intersection in all directions. The study area may be expanded
beyond the minimum to include intersections where high turning
conflicts are anticipated.
2. The study area for urban developments that propose access points
within or adjacent to an interconnected traffic signal system, and that
will require a progression analysis as part of a TIA, should include the
intersections comprising the signal system. Where a signal system
consists of more than three signalized intersections, the extent of the
progression analysis should be determined by the City Traffic
Engineer.
b. Rural Study Areas: The TIA study area for developments located on
roadways in Access Categories RPA, RMA and RCOL should be
determined based on the following guidelines for rural conditions.
1. Rural study areas should include all site access points, the roadway
segments immediately adjacent to the access points and major
intersections expected to be used by development traffic to access the
regional highway system, if any.
2. Rural developments along isolated roadway segments, having no
intersecting collector or higher classified roadways within 5 miles in
either direction and which generate 200 design hour trips or less,
should have the study area defined as the site access points plus the
roadway segments immediately adjacent to the assess points.
3. Rural developments along isolated roadway segments, having no
intersecting collector or higher classified roadways within 5 miles in
either direction and which generate more than 200 design hour trips,
should have the study area defined as the site access points plus the
adjacent roadway segments and the first collector or higher classified
cross-street intersection in each direction.
c. Safety Analysis: Three years of accident history should be reviewed for the
major study area intersections. Intersection collision diagrams should be
prepared showing the number of accidents, accident type, date and time of
each accident, and accident severity. The intersection accident rate per
million entering vehicles (acc/MEV) should be indicated on the collision
diagram. The safety analysis should include a field review of the site.
d. Non-Phased Development Analysis Years: The TIA analysis years to be
evaluated for non-phased developments are defined below.
1. Existing Year Conditions
2. Implementation Year without the Proposed Development
3. Implementation Year with the Proposed Development
4. Horizon Year without the Proposed Development
5. Horizon Year with the Proposed Development
The existing year should be defined as the year the existing condition
traffic counts are obtained. The implementation year should be defined
as the calendar year that the proposed development is expected to
commence operation. The horizon year should be the implementation
year plus ten years.
e. Phased Development Analysis Years: A phased development should
require the same TIA analysis years as described in Sub-Paragraph D.1.d.
(above), except the horizon year should be the year of full development
plus 10 years. Additionally, the horizon year should not be greater than the
existing year plus 20 years. Depending on the type and scale of the
proposed phased development, and considering study area conditions,
additional implementation year analyses may be required. The additional
analysis years should be identified at the TIA scoping meeting. The total
number of analysis years for a phased development should not exceed four
(i.e., there are currently two excluding existing conditions; no more than two
additional analysis years may be required).
f. Analysis Peak Periods: Traffic analysis should be performed for the AM
peak hour and the PM peak hour of a typical weekday, or for the design
hour associated with special traffic conditions. For future-year analyses
beyond the initial implementation year analysis, the permittee may request
that the futureyear analyses be performed only for the critical peak hour,
identified based on the existing conditions analysis and the anticipated trip
generation characteristics of the proposed development. The permittee
should be prepared to make this request at the traffic analysis scoping
meeting.
g. Trip Generation: Trip generation estimates should be based on the type
and intensity of the proposed land use, and should include estimates of
daily and peak-hour travel. The ITE Trip Generation Manual (Sub-Section
9.F) should be used when the proposed land use is reasonably consistent
with the land use categories and descriptions contained in the Trip
Generation Manual. When the land use categories of the Trip Generation
Manual clearly do not apply or the rates are not appropriate for a proposed
development, locally derived trip generation rates should be used. Trip
generation rates that are based on local conditions should be developed
according to the methodology described in the Trip Generation Manual.
h. Trip Distribution and Assignment: Trip distribution and assignment may be
performed using manual techniques or a computer model. The trip
distribution methodology should consider the area population, locations of
similar land use, and travel distances. Trips should be assigned to the
major street system based on logical routing patterns. The major street
system includes streets classified as collectors and above. Trips may be
assigned to the local street system when the local street provides direct
access to the proposed development. Refer to Section 7 for definitions of
trip distribution and trip assignment.
i. Traffic Projections: Implementation year and horizon year traffic projections
should include background traffic growth, trips generated by other known
development projects in the study area, and trips generated by the
proposed development, as appropriate. Other known developments should
be considered built out or, if a phased development, built out according to
the phasing schedule. Other known development projects within the study
area should be included when:
1. A development existed but was inactive when the existing condition
traffic counts were collected, or
2. A development was under construction at the time the existing
condition traffic counts were collected, or
3. A development opened since the existing condition traffic counts were
collected, or
4. A development was issued an access permit by the Department since
the existing condition traffic counts were collected. (The City Traffic
Engineer should inform the applicant of this condition at the scoping
meeting.)
j. Intersection Traffic Analysis: Signalized and unsignalized intersections
should be analyzed consistent with the current Highway Capacity Manual
methodologies. Signalized intersections that are not part of a traffic signal
system should be analyzed as isolated intersections. These analyses may
be performed using the current versions of the Highway Capacity Software,
TeaPac, or other analysis packages approved by the NMSHTD Traffic
Technical Support Section. Signalized intersections that are part of a
coordinated traffic signal system should require a progression analysis to
be performed using TRANSYT-7F.
k. Roadway Segment Traffic Analysis: The capacity of specific roadway
segments on two-lane highways and multi-lane highways should be
evaluated when the traffic flow along the facility is not influenced by
signalized intersection operations. This occurs where the average spacing
of signalized intersections is greater than one signal installation per mile.
Where a proposed access point is more than 500 feet from an isolated
signalized intersection (i.e., there are no adjacent signalized intersections
within one mile), roadway segment capacity analysis may be required. A
roadway segment traffic analysis may be required for any traffic analysis
when the directional volume passing the proposed access exceeds 1,200
vehicles per hour per lane.
l. Measuring Impacts: The analysis years of a TIA should include an impact
assessment by intersection and/or roadway segment. The TIA should
include a discussion of how the impacts were identified for a particular
development. Impacts should be measured based on one or more of the
following comparisons:
1. Isolated intersection performance statistics without and with the
proposed development.
2. Roadway segment performance statistics without and with the
proposed development.
3. Traffic signal progression analysis results without and with the
proposed development.
4. Traffic volume comparison without and with the proposed development
showing the magnitude and percent change in traffic volume by
intersection approach movement.
m. Graphics: The TIA documentation should contain a vicinity map showing all
arterial and collector roadways within a reasonable influence area of the
site, a study area map denoting the intersections included in the analysis,
and a site plan that details the site access location(s) and internal
circulation patterns. In addition to proposed land use details, the site plan
should include dimensions to adjacent property boundaries and to adjacent
access points along the site frontage, and should indicate locations of
access points along the frontage on the opposite side of the highway.
n. Documentation: All required traffic impact analyses shall include
documentation in the form of a bound report. The TIA documentation
should discuss the following:
1. Study Purpose;
2. Development description;
3. Study area land use description;
4. Existing roadway and traffic conditions;
5. Safety analysis (3-years);
6. Background traffic growth;
7. Trip generation, distribution and assignment;
8. Traffic projections;
9. Detailed traffic analysis for each analysis year, including traffic signal
warrants;
10. Impact assessment for each analysis year;
11. Proposed site circulation and parking plan;
12. On-site and off-site queue lengths;
13. Non-motorized impacts;
14. Access design specifications;
15. Summary of deficiencies and proposed mitigation for each analysis
year; and,
16. Appended materials.
o. Fair Share Cost Analysis: Based on the impact assessment completed for
the STA or TIA, contributory costs of identified improvements should be
identified. In addition to implementing the necessary improvements within
the roadway right-of-way at proposed site access points, the permittee shall
be required to provide all or a portion of funding for mitigation of identified
off-site impacts. The funding requirements shall be determined by the
Department through negotiations with the developer and the appropriate
local government agency.
p. Traffic Study Validity Period: Approved traffic studies should remain valid for
a period of one-year following approval of the driveway permit application, or
as determined by the City Traffic Engineer or their designee. Below is a list of
street classifications and their abbreviations:
1. UINT – Urban Interstate
2. UPA – Urban Principal Arterial
3. UMA – Urban Minor Arterial
4. UCOL – Urban Collector
5. RINT – Rural Interstate
6. RPA – Rural Principal Arterial
7. RMA – Rural Minor Arterial
8. RCOL – Rural Collector
13.4.3 Engineering qualifications. The STA and TIA shall be prepared under the direction of a
professional engineer (civil) licensed to practice in the State of New Mexico with specific
experience in traffic engineering and the preparation of STA and TIA reports.
