Gewalt Hamilton Associates, Inc. 1
Part I. Introduction and Project Context
Gewalt Hamilton Associates, Inc. (GHA) has conducted a Traffic Impact and Parking Study for the proposed addition
to McHenry West High School located at 4723 Crystal Lake Road in McHenry, Illinois. Access to the site is currently
provided via three driveways on Crystal Lake Road, along with an exit-only drive onto Oakwood Drive. The main
parking facility is located on the southern portion of the site and serves parent drop-off/pick-up operations, student
parking, overflow staff parking, as well as bus loadings. Students and parents access the main parking facility via the
main (south) driveway on Crystal Lake Road. The center (bus-only) drive lane, that is also accessed via Crystal Lake
Road, runs along the entirety of the eastern side of the building and loops around to the main southern student
entrance. Bus loadings occur at this main entrance and on the west side of the building, which is accessed by buses
via the aforementioned drive lane. This drive lane continues around the entire building and exits through the northern
parking facility onto Oakwood Drive. A smaller staff parking lot is provided on the northern portion of the site, accessed
via a (north) driveway also on Crystal Lake Road, just to the south of Royal Drive. The McHenry Community High
School District 156 office building is also located in the northwest corner of the staff parking lot.
As currently proposed, an expansion will take place on the north side of the existing building. The expansion would
eliminate the trailers currently used as overflow classrooms, as well as include the implementation of a Science,
Technology, and Industry Center on site, along with an expansion of parking facilities and tennis court
expansions/renovations. With the planned expansion, the West Campus would serve Sophomores through Seniors,
while the East Campus would transition to Freshmen only. The ultimate student capacity with the proposed addition
is approximately 2,000 students.
This Traffic Impact and Parking Study evaluates traffic access, safety, parking and/or on-site circulation. The following
summarizes our findings and provides various recommendations for your consideration. Appendices referenced are
in the Technical Addendum at the end of this document.

Note: No pedestrian connections to McHenry High School from the sidewalk along the west side of
Crystal Lake Road currently exist. Students coming from the south enter the student parking lot through
the southeast corner, rather than continuing north through the South High School Access intersection
along Crystal Lake Road.
Existing Traffic
Peak period traffic turning movement and pedestrian counts were conducted by GHA on Wednesday, January
16, 2018 from 6:30 to 9:30 AM and 2:00 to 6:00 PM. Exhibit 3A summarizes the existing weekday morning,
afternoon school and evening street peak hour traffic volumes. Exhibit 3A also provides the AADT (24-hour
volume) as published by IDOT on their website www.gettingaroundillinois.com. Exhibit 3B illustrates the
pedestrian crossing data.
The results indicate that the peak hour of existing traffic during the weekday morning street and morning school
peaks coincided and occurred from 6:30 to 7:30 AM, while the weekday afternoon school peak occurred from
2:30 to 3:30 PM and the weekday evening street peak occurred from 4:30 to 5:30 PM.
No unusual activities (e.g. roadway construction, or inclement weather) were observed during our counts that
would be expected to impact traffic volumes or travel patterns in the vicinity. Summaries of the existing traffic
counts can be found in Appendix B.
Existing Parking
Parking Survey
The exhibit contained in Appendix C shows an aerial photo of the study area and the parking areas surveyed.
GHA conducted an inventory of the parking spaces available in each area shown. Six-hundred and fifty (650)
vehicle spaces were surveyed in total and the number of spaces by parking area is listed in Table 1.

Parking Occupancy
In order to determine the existing parking demand in the study area, GHA conducted parking occupancy surveys
of each of the parking areas listed above. The parking surveys were conducted hourly on Wednesday, January
16, 2018 between 9:30 AM and 11:30 AM. These times were chosen as they represent the peak hours of
occupancy based on predicted usage during the day for the existing high school use.

Parking Occupancy (cont.)
The exhibit contained in Appendix C tabulates the results of the parking surveys in the study area. The results
of the survey indicate the following key findings and observations:
The peak parking demand occurred at 9:30 AM. Overall, 650 vehicle (regular and facility bus) parking spaces
were surveyed and, at most, approximately 78 percent (503 spaces) are occupied.
Four-hundred and three (403) passenger vehicle (student and accessible) spaces are provided for students.
At most, approximately 78 percent (315 spaces) were occupied.
Two-hundred and forty-five (245) passenger vehicle (regular, visitor, staff and accessible) spaces are
provided for high school and district office staff, as well as supporting activities (i.e., driver’s education) and
maintenance. At most, approximately 77 percent (189 spaces) were occupied.
Two (2) spaces for activity buses were 100 percent occupied.
Parking was well utilized within the north (Area A) staff lot, experiencing at and/or above capacity, with
vehicles parking in unmarked spaces.
Existing Operational Observations
Observations were conducted of the McHenry West High School’s morning and afternoon peak hours. Some of
these observations, which are depicted on Exhibits 4A/B, include the following:
Morning Peak Hour
Buses currently drop-off during the morning peak hour within the south parking lot at the south school
entrance/exit. It was observed that no more than two bus were parked at any given time to drop-off students.
The combination of students entering from their car, bus drop-off traffic, and parent drop-off traffic during the
morning peak hour at the south school entrance/exit creates increased conflict potential between all users.
The queue (stacking) of vehicles during the morning peak period is contained within the drop-off lane (26
vehicles).
A Police Officer is present at the Crystal Lake Road and South High School Access intersection to facilitate
traffic.
Observations revealed that back-ups in the southbound and northbound direction on Crystal Lake Road at
all the high school access drives occurred during peak arrival times of the school.
It was observed that the students walking to school from the subdivisions to the south would enter the South
Student Parking Lot from the southeast corner prior to reaching the South Access intersection along Crystal
Lake Road. This is likely due to the danger of crossing at this intersection due to the number of vehicles
maneuvering in/out.
A School Guard is stationed at the North Access intersection with Crystal Lake Road to help facilitate the
crossing of students into the north entrance of the High School.
Afternoon Peak Hour
Buses currently pick-up during the afternoon peak hour on the west side of the building (See #1 on Exhibit
4B). During observations, all buses arrived prior to the end of school at 2:50 PM.
The queue (stacking) of vehicles during the afternoon peak period extends onto Crystal Lake Road just past
the southbound right-turn lane taper (58 vehicles).
The exiting student and parent traffic circulation pattern is displayed on Exhibit 4B. Students are forced to
exit outward (north or south) from the center drive aisle to head west and loop back around and utilize the
center drive aisle as queueing for exiting onto Crystal Lake Road. Cones are setup by school staff to facilitate
operations. It was observed that the current systems work efficiently, as the entire afternoon release cycle
lasted approximately 17 minutes.

Afternoon Peak Hour (cont.)
A Police Officer is present at the Crystal Lake Road and South High School Access intersection to facilitate
traffic. School staff are also present to help facilitate traffic at the west end of the center drive aisle and where
the parent pick-up traffic re-enters the parking lot. Both locations are marked on Exhibit 4B. Note: more
students cross the South Access intersection and heading south, as compared to crossing north in the
morning.
Similar to the morning peak hour, a School Guard is stationed at the North Access intersection with Crystal
Lake Road to help facilitate crossing students from the north entrance of the High School.
Existing School Characteristics
The current student enrollment at McHenry West High School is 1,434 students.
The school is supported by approximately 140 staff members.
Crash Analysis
In order to evaluate and address potential safety issues at the study area intersections, crash data was obtained
from the IDOT Division of Transportation Safety for the last five calendar years available, 2012 through 2016.
However, IDOT does not keep record of crashes that occur in parking lots. Crash data was obtained for the school
parking lots from the City of McHenry for the last three calendar years available, 2015 through 2018. A summary
of the crash data is provided in Table 2, with the locations of the IDOT data mapped on the exhibit contained in
Appendix D.

As shown in Table 2, the intersection of Crystal Lake Road and Royal Drive experienced the highest amount of
crashes within the study area over the five-year analyses period. There was an average of ten (10) crashes per
year at this location. Seventy-eight (78) percent (39 of 50) of the crashes at Crystal Lake Road and Royal Drive
involved property damage and 58 percent (29 of 50) were rear-end collisions.
Amongst all three high school access drives, 16 crashes occurred during the analyses period, or, on average,
approximately three (3) crashes per year. Approximately 81 percent (13 of 16) of these crashes involved property
damage only and 75 percent (12 of 16) were rear-end collisions. Within the high school parking lots, 22 crashes
occurred during the three year analyses period, from 2015 to 2018. Approximately 91 percent (20 of 22) of the
crashes involved property damage, while approximately 9 percent (2 of 22) involved “Type C” injuries, which is
the lowest potential category.
There were two crashes that involved a pedestrian – one at the Crystal Lake Road and Royal Drive intersection
and one occurring between the Crystal Lake Road and Kensington Drive intersection. There were no crashes
that involved a bicyclist.
2030 No-Build (Non-Site) Traffic
Exhibit 5 summarizes the 2030 No-Build weekday morning, school afternoon and evening street peak hour traffic
volumes. This identifies background, or ambient, projected growth in traffic conditions without the site traffic.
Future traffic volume conditions were developed for the anticipated opening year of the development plus ten years,
year 2030. For the purpose of this study and based on a review of historical traffic volumes, the Chicago
Metropolitan Agency for Planning (CMAP) 2050 projections (see Appendix E), traffic volumes along the
roadways surrounding the site are assumed to experience an overall annual, compounded growth rate of
approximately 1 percent per year. Accordingly, the 2030 peak hour traffic volumes were developed by applying
a 1 percent compounded annual growth rate to the existing traffic (Exhibit 3A).
It should be noted that alternative projections provided by CMAP include a scenario where a potential roadway
widening project would be completed along IL Route 31. If this roadway is widened from two to four lanes, it
would potentially reduce future traffic volumes along the study area roadways. However, there is no construction
scheduled or funding to implement the improvements at this time; therefore, the higher volume projections were
chosen in these analyses to provide a conservative case scenario.

Part IV. Traffic Evaluation
Future Site Characteristics
Proposed Development
The McHenry Community High School District (District 156) is planning an expansion to McHenry West High
School. The expansion would occur on the north side of the existing building and eliminate the trailers currently
used as overflow classrooms. It will also include the implementation of a Science, Technology, and Industry
Center on site, along with an expansion of parking facilities and tennis court expansions/renovations. With the
planned expansion, the West Campus would serve Sophomores through Seniors, while the East Campus would
transition to Freshmen only. The ultimate student capacity with the proposed addition is approximately 2,000
students. The site plan is provided as Exhibit 6.
The existing tennis courts located just west of the South Student Lot are to be replaced with a new parking area.
Ten (10) new tennis courts will be installed just southwest of the proposed new parking area. The net gain of
parking spaces with the addition to the South Student Lot is approximately 213 spaces. Additionally, the North
Staff Lot will be reconstructed as depicted on Exhibit 6. The parking stalls have been altered from angled to 90
degree spaces, which now facilitates two-way traffic down all drive aisles. The lot will be expanded to the
northeast to gain additional spaces, bringing the parking spaces net gain on this lot to 11 spaces. Overall,
between the two modifications, the McHenry West High School will provide an additional 224 spaces on top of
the 650 spaces currently supplied, bringing the proposed total up to 874 parking spaces.
Trip Generation
Exhibit 7 – Part A tabulates the traffic generation calculations for the proposed development. Trip generation
rates published by the Institute of Transportation Engineers (ITE) in the 10th Edition of the Manual Trip Generation
were reviewed, along with the existing traffic count data and current student population date to determine the
anticipated traffic generated by the proposed high school addition, See Appendix F for excerpt from the ITE
manual. The trip generation was estimated using the current student population (1,434 students) in coordination
with the maximum student capacity after the proposed expansion (2000 students).
Per the ITE excerpt, the school’s morning and afternoon peak hour volumes are not consistent with the ITE data.
As shown on Exhibit 7, McHenry West High School experiences higher than anticipated (ITE calculated) traffic
volumes during the morning and afternoon peak hour, as well as during the evening adjacent street peak.
Accordingly, the local data was used in our future analyses to provide a realistic analysis scenario.
As previously described, the High School will experience a demographic shift from the current Freshmen to Senior
population, to a Sophomore though Senior campus. The combined existing Sophomore through Senior
population at both McHenry West (1,069) and East (638) High Schools is 1,707 students. The future conditions
calculations considered this shift in demographics, which will result in an increase in student driver population
and supporting staff, with a potential decrease and/or minimal change in parent drop-off/pick-up activity, due to
higher drop-off/pick-up activity associated with non-driver aged students (predominately Freshmen) being
removed from the McHenry West High School. Over the past ten years, the student population within School
District 156 has remained relatively flat, with minimal, if any growth. However, to provide a conservative analysis
scenario, the trip generation for the estimated increase in student population was projected based on the
maximum student capacity after the proposed expansion (2000 students).

Directional Distribution
Exhibit 7 – Part B provides the anticipated distribution of new site traffic. This was based on existing site travel
patterns and operational characteristics. Due to the location of the East McHenry High School (which is where
the increase in student population will originate from), it was estimated that no new students, parents, or staff
would be entering or exiting the site from Dartmoor Drive, Royal Drive, or Kensington Drive. The new trips
generated would be travelling west, from the east side of McHenry, and reaching the High School via Crystal
Lake Road.
Traffic Signal Warrant Analyses
A traffic signal warrant analysis was performed for the intersection of Crystal Lake Road and McHenry HS South
Access. The analysis was based on the MUTCD criteria for installation of a traffic control signal. The warrant
analysis considers peak hour traffic volumes at the intersections and makes comparisons to minimum traffic
volume thresholds to determine if the installation of a traffic signal should be considered. The MUTCD is the
standard reference application of traffic signals and contains eight different warrant types for the justification of
traffic signals. It is stated that if one or more of the warrants are satisfied, a traffic signal is justified and could be
installed. However, a number of factors are involved in determining if traffic signal control should be installed,
including intersection operations, safety, and engineering judgment.
Section 4C.04, Warrant 2 – Four Hour and Warrant 3 - Peak Hour of the MUTCD, were examined to determine
whether a traffic signal was warranted under existing and future (year 2030) conditions due to the amount of
delay that a minor street suffers when entering a major street. In order for a traffic signal to be warranted under
this condition, the plotted point representing the vehicles per hour on the major street (total of both approaches)
and the corresponding vehicles per hour on the higher-volume minor street approach (one direction only) for 1
hour of an average day for Warrant 3, and 4 hours on an average day for Warrant 2 must fall above the applicable
curve on Figure 4C-1 and Figure 4C-3, respectively, of the MUTCD for the existing combination of approach
lanes. The graphical representation and the application of the estimated traffic volumes are shown on the figures
provided in Appendix G, which includes a reduction for right-turn on red (RTOR), utilizing Pagones’ Theorem,
which is consistent with IDOT requirements for new traffic signal installation.
The results of the most applicable traffic signal warrant tests are discussed below:
Warrant #2 – Four Hour Volume
Appendix G.1-2 presents Figure 4C-1 from the MUTCD, which was utilized to determine if the Four-Hour
Warrant was met. As can be seen, there are only two hours during existing conditions and three hours during
2030 future conditions where the minimum combined volumes met above the minimum threshold line on the
chart. Therefore, the Four-Hour volume criteria is not met.
Warrant #3 – Peak Hour Volume
Appendix G.3-4 presents Figure 4C-3 from the MUTCD, which was utilized to determine if Warrant #3 - Peak
Hour Volume was met. The highest peak hours throughout the study area occurred from 6:30-7:30 AM, 2:30-
3:30 PM, and 4:30-5:30 PM. Each of these hours was tested. However, the combination of volumes met
below the minimum threshold line on the chart for all three hours during exiting conditions. Under 2030 future
conditions, the peak hour warrant was satisfied during both the weekday morning (6:30 to 7:30 AM) and
afternoon school (2:30 to 3:30 PM) peak periods.
McHenry West High School
McHenry, Illinois
Gewalt Hamilton Associates, Inc. 19
Based on the above discussion, a traffic signal is not warranted at the intersection of Crystal Lake Road and
McHenry HS South Access during existing conditions. However, a traffic signal is warranted based on Warrant
#3 -Peak Hour under future (year 2030) conditions during both the weekday morning and afternoon school peak
hours, which assumes full-build out (2,000 student population) of the high school along with a conservative,
general background growth in the study area. The spacing from this intersection to the existing traffic signal to
the north (Royal Avenue) exceeds a desirable spacing of ¼-mile (1,320 feet); however, is located slightly closer
to the existing signal to the south (Dartmoor Drive) – at approximately 1,100 feet. A ¼-mile spacing is desirable
to permit acceptable progression along Crystal Lake Avenue.
Site and Total Traffic Assignments
Exhibit 8 illustrates the site traffic assignment for the new high school trips, which is based on the traffic
characteristics summarized in Exhibit 7 (traffic generation and trip distribution) and assigned to the area
roadways. The site traffic and 2030 No-Build traffic (see Exhibits 8 and 5, respectively) were combined to produce
the 2030 Total traffic, which is illustrated on Exhibit 9. Additionally, Appendix H provides site traffic excerpts,
with the values separated out by use (student traffic, bus traffic and drop-off/pick-up traffic).
Capacity Analysis
Capacity analyses are a standard measurement that identifies how an intersection operates. They are measured
in terms of level of service (LOS). The concept of LOS is defined as a qualitative measure describing operational
conditions within a traffic stream and their perception by motorists and/or passengers. A level-of-service definition
provides an index to quality of traffic flow in terms of such factors as speed, travel time, freedom to maneuver,
traffic interruptions, comfort, convenience, and safety.
Six levels of service are defined for each type of facility. They are given letter designations from A to F, with LOS
A representing the best operating conditions and LOS F the worst. LOS C is often considered acceptable for
design purposes and LOS D is usually considered as providing the lower threshold of acceptable operations.
Since the level of service of a traffic facility is a function of the traffic flows placed upon it, it may operate at a wide
range of levels of service, depending on the time of day or day of the week. A description of the operating
condition under each level of service, based on the analysis parameters as published in the Transportation
Research Board’s (TRB) Highway Capacity Manual (HCM), Sixth Edition, is provided in Table 3.
Table 3: Level of Service (LOS) Summary
LOS Description
Delay (sec/veh)
Traffic Signal Stop Sign
A Describes conditions with little to no delay to motorists. <10 < 10
B Represents a desirable level with relatively low delay to motorists. >10 and < 20 >10 and < 15
C Describes conditions with average delays to motorists. >20 and < 35 >15 and < 25
D Describes operations where the influence of congestion becomes more
noticeable. Delays are still within an acceptable range. >35 and < 55 >25 and < 35
E
Represents operating conditions with high delay values. This level is often
considered within urban settings or for minor streets intersecting major
arterial roadways to be the limit of acceptable delay. >55 and < 80 >35 and < 50
F Is considered to be unacceptable to most drivers with high delay values that
often occur, when arrival flow rates exceed the capacity of the intersection. >80 >50

An intersection capacity analysis was used to analyze the intersections for the weekday morning, afternoon
school, and evening street peak hours using the methodologies outlined in the HCM using Synchro v10 software,
for the following scenarios:
Existing Traffic - Existing traffic (year 2019),
No-Build Traffic – Future (non-site, year 2030) traffic with background growth (assumed at 1 percent
compounded per year), and
Total Traffic – Future No-Build traffic volumes (year 2030) plus the addition of site generated traffic.
The Synchro models were then simulated using SimTraffic, which is a dynamic modeling program. It animates
the roadway network and models the interactions between each individual vehicle on the roadway. This animated
model provides the full extent of the delays and traffic backups, as it considers the traffic spillback between
intersections and beyond turn bays, unbalanced lane use, and other subtle traffic flow interactions.
Table 4 on the following pages summarizes the intersection capacity analysis results and calculated 95th-
percentile queues. Capacity analysis summary printouts are provided in Appendix I.

Traffic Impact Discussion
1. The signalized intersections at Dartmoor Drive and Royal Drive with Crystal Lake Road currently experience
acceptable levels of service for overall intersection operations during the weekday morning, afternoon school,
and evening street peak hours. Under future No-build (year 2030) conditions, these signalized intersections
still operate under acceptable levels of service. However, after the addition of new site traffic, individual
movements begin to deteriorate. During the future Total (year 2030) traffic, eastbound Dartmoor Drive begins
to operate with unacceptable levels delay, at LOS F. Future signal timing modifications are presented as
Table 5 in Appendix J and were implemented to help mitigate the effects of the proposed site traffic.
2. As stated above, in order to accommodate future Total conditions, the traffic signal timing modifications in
Appendix J were applied to the intersection at Dartmoor Drive with Crystal Lake Road. Without adjustments
under future conditions, traffic operations could function under significant constraints. The modifications
made at Crystal Lake Road and Dartmoor Drive help to facilitate the increased amount of through traffic along
Crystal Lake Road from the proposed High School addition. The proposed timing changes increase time
given to northbound and southbound through movements. Furthermore, the minor street (Dartmoor Drive)
movements are adjusted slightly to help facilitate traffic onto and off of Crystal Lake Road.
3. As explained earlier in the report, it should be noted that alternative projections provided by CMAP include a
scenario where a potential roadway widening project would be completed along IL Route 31. If this roadway
is widened from two to four lanes, it would potentially reduce future traffic volumes along the study area
roadways, which would decrease delays. However, there is no construction scheduled or funding to
implement the improvements at this time; therefore, the higher volume projections were chosen in these
analyses to provide a conservative analysis scenario.
4. Eastbound movements from Kensington Drive onto Crystal Lake Road currently operate under capacity
constraints during the morning and afternoon school peak hours at LOS E. Under future No-Build and Total
conditions, all three peak hours will begin to operate at unfavorable conditions. It is important to note that
the 95th queue length (worst case scenario) reaches approximately 100 feet, which is around 5 cars. This is
a typical scenario for a minor street intersecting an arterial roadway with heavy through traffic volumes.
5. Currently, the Crystal Lake Road and McHenry HS South Access intersection operates under Police Control
during both the morning and afternoon school peak hours. Accordingly, the movements at this intersection
operate similar to under traffic signal control. Under existing conditions, the analysis displays that all
movements operate under no capacity constraints, at LOS D or better. However, it is important to keep in
mind that the modeling software examines the average worst delay over a one-hour period of time. As such
is the case with most schools, drop-off and pick-up operations are condensed to approximately 30-minute
periods of time. During GHA’s site observations in January 2019, it was noted that backups do occur along
Crystal Lake Road, particularly during the morning peak hour. With no changes to school operations, the
South Access intersection will operate at LOS E during the morning peak hour, with significant delays to
eastbound movements, as well as northbound lefts and southbound rights into the parking lot. The analysis
displays that this intersection operates under no capacity constraints during the afternoon school peak hour;
however, some movements are constrained during the evening street peak hour. Due to no Police Officer
being present at the intersection during the evening street peak hour, vehicles will experience more delay
while maneuvering from the parking lot onto Crystal Lake Road.
6. The Crystal Lake Road and Center Access intersection experienced minimal delays during all hours studied.
This is likely due to the “entrance-only” nature of this intersection. However, residual delays along Crystal
Lake Road may affect northbound and southbound operations.
7. The North Access intersection with Crystal Lake Road has one movement that operates under constraints
during all scenarios and peak hours analyzed. Eastbound left turns from the parking lot onto Crystal Lake
Road operate at LOS E, with the maximum queue length reaching approximately 78 feet, which is 4 cars.
8. The intersection at Royal Drive and Oakwood Drive/Northfox Lane operates without constraints under both
existing and future conditions.

Future Parking Analyses
Analysis was conducted to determine the number of parking spaces required to accommodate the new high
school addition. In order to project future peak parking demand, GHA referenced two sources: the parking counts
conducted by GHA in January 2019 at the subject site (see Appendix C) and requirements per City of McHenry
Code. Table 6 summarizes the peak parking demand projections from each of the two sources.

3 Drivers Ed., Activities, etc.
4 Accessible spaces required by law, represents supply instead of demand.
5 One space per 4 students.
As shown in Table 6, a minimum of 876 parking spaces should be provided to accommodate the anticipated
future parking demand should McHenry West High School reach its capacity of 2,000 students. Note, this
conservatively assumes a future parking policy similar to existing, which provides a parking space / permit for all
student requests. It is not uncommon, and is often typical practice, for high schools to implement a parking policy
which permits parking based on a lottery system, with priority typically given to Senior, honor roll students, etc.
Accordingly, it is recommended that parking be monitored with growth in student enrollment to determine if
modifications to the existing parking policy are required. Consideration should also be given to providing assigned
(numbered) parking spaces within the student parking lot to minimize internal circulation and traffic impacts.
Measures should also be considered to reduce future parking demand including providing adequate pedestrian
and bicycle infrastructure that is easily accessible, along with programs/education to encourage the use of school
buses and non-auto modes (walking and biking) as primary means to access the school.

Part V. Conclusions
A traffic impact and parking study was performed for the proposed addition to the existing McHenry West High
School located at 4723 Crystal Lake Road in McHenry, Illinois. Existing and future conditions in the study area
have been described, analyzed and evaluated with respect to traffic operations and the impact of the planned
development. Conclusions of this effort are presented below:
1. The proposed development includes an addition to the north side of the existing building, including STEM
laboratories. Additionally, new parking and tennis courts will be added to the area south of the High School.
2. The school is anticipated to serve a future student enrollment of 2000 students, with the student population
transitioning from the current Freshmen through Senior campus to the proposed Sophomore through Senior
campus.
3. Continued collaboration with McHenry High School Staff and District 156 staff is needed to evaluate
alternative circulation scenarios with the end goal of increasing the efficiency of operations and maintaining
safety for all users- students, staff, and parents. In order to accomplish this, internal site improvements could
be considered, such as a new connection between the north parking lot and the bus lane in the area of the
northeast corner of the building. Consideration could also be given to providing a new access point on Crystal
Lake Road and/or relocating existing access, provided adequate spacing between intersections and
improved operations are provided.
4. Trip generation for the increase in student population for the design year (2030) was quantified for the
weekday morning, afternoon school and evening street peak periods, using local trip generation rates, which
produced higher results than industry standard (ITE Trip Generation).
5. Analyses have been conducted for all study intersections to determine the impact from the planned
development, along with general growth within the study area (assumed at 1 percent compounded per year)
to the 2030 design year.
6. The current parent drop-off/pick-up lane does not provide sufficient stacking to accommodate the future
growth in student enrollment. Based on the existing, typical vehicle queue observed at 26 vehicles during
the morning peak hour and 58 vehicles during the afternoon school peak hour, and a proportional increase
based on the growth in student population and shift in student demographics, stacking for a minimum of 29
vehicles should be provided during the morning peak hour and staking for a minimum of 65 vehicles should
be provided for the afternoon school peak hour.
7. Several of the movements at the study area intersections along Crystal Lake Road currently experience
capacity constraints during the weekday morning and afternoon school and street peak periods. These
intersections are anticipated to continue to operate at these levels with the anticipated general growth in
background traffic, as well as additional site traffic (increase in student population). The modified signal
timings help to reduce congestion and promote increased progression along Crystal Lake Road.
8. A minimum of 876 parking spaces should be provided on site to account for the maximum (2,000 students)
anticipated growth in student enrollment / increase in staff. It is recommended that the parking facilities be
monitored for future on-site parking needs, if/when growth in student population warrants, with consideration
to modifications to its existing parking policy to include limiting number of student parking permits issued
and/or providing assigned (numbered) parking within the student parking lots to minimize circulation / traffic
impacts.
9. A pedestrian connection from the sidewalk along the west side of Crystal Lake Road into the High School
should be considered. Currently, no such connection exists, and some students must traverse through the
parking lots to enter the school.

Dear Mr. Opitz:
In response to a request made on your behalf and dated January 14, 2019, we have
developed year 2050 average daily traffic (ADT) projections for the subject location.

Traffic projections are developed using existing ADT data provided in the request letter
and the results from the October 2018 CMAP Travel Demand Analysis. The regional
travel model uses CMAP 2050 socioeconomic projections and assumes the
implementation of the ON TO 2050 Comprehensive Regional Plan for the Northeastern
Illinois area. The provision of this data in support of your request does not constitute a
CMAP endorsement of the proposed development or any subsequent developments.
If you have any questions, please call me at (312) 386-8806.

Traffic Signal Warrant Analyses
Appendix G
Analysis Parameters – “Pagones’ Theorem”
Appendix G.1 Crystal Lake Road & South Access Existing Traffic Volumes Major (Crystal Lake Road) Minor (South Access)* 6:30 to 7:30 AM = 1258 VPH 171 VPH 2:30 to 3:30 PM = 1021 VPH 220 VPH 3:30 to 4:30 PM = 1216 VPH 80 VPH 4:30 to 5:30 PM = 1344 VPH 76 VPH *Includes RTOR reduction using Pagones’ Theorem. Result Intersection volumes do meet Warrant #2 from 6:30 to 7:30 AM and 2:30 to 3:30 PM. However, not for the other two hours.
Appendix G.2 Crystal Lake Road & South Access 2030 Total Traffic – Option 1 Volumes Major (Crystal Lake Road) Minor (South Access)* 6:30 to 7:30 AM = 1785 VPH 194 VPH 2:30 to 3:30 PM = 1182 VPH 409 VPH 3:30 to 4:30 PM = 1401 VPH 116 VPH 4:30 to 5:30 PM = 1548 VPH 110 VPH *Includes RTOR reduction using Pagones’ Theorem. Result Intersection volumes do meet Warrant #2 from 6:30 to 7:30 AM, 2:30 to 3:30 PM, and 3:30 to 4:30 PM. However, volumes do not meet the warrant from 4:30 to 5:30 PM due to 110 VPH on the minor street approach being below the 115 VPH threshold.
Appendix G.3 Crystal Lake Road & South Access Existing Traffic Volumes AM Peak School Peak PM Peak Major Street – Crystal Lake Road = 1,258 VPH 1,021 VPH 1,344 VPH Minor Street – South Access* = 171 VPH 220 VPH 76 VPH *Includes RTOR reduction using Pagones’ Theorem. Result Intersection volumes do not satisfy Warrant #3 Peak Hour, during any of the three peak hours.
Appendix G.4 Crystal Lake Road & South Access 2030 Total Traffic – Option 1 Volumes AM Peak School Peak PM Peak Major Street – Crystal Lake Road = 1,785 VPH 1,182 VPH 1,548 VPH Minor Street – South Access* = 194 VPH 409 VPH 110 VPH *Includes RTOR reduction using Pagones’ Theorem. Result Intersection volumes do meet Warrant #3 from 6:30 to 7:30 AM (AM Peak) and 2:30 to 3:30 PM (School Peak). However, volumes do not meet the warrant from 4:30 to 5:30 PM (PM Peak) due to 110 VPH on the minor street approach being below the 150 VPH threshold.
