Downtown Skokie & Oakton Street Corridor Study (Draft) Skokie, Illinois Project Manager: William C. Grieve, P.E., PTOE GHA Project #3261.805 Downtown Skokie & Oakton Street Corridor Study Skokie, Illinois June 9th, 2010

Executive Summary Oakton Street Corridor Study May 28, 2010 Gewalt Hamilton Associates, Inc (GHA) was retained by the Village of Skokie to conduct a comprehensive traffic study of a 0.66 mile segment of Oakton Street from Park Avenue on the west to Skokie Boulevard on the east. The purpose of the study was to evaluate the potential ways of calming traffic on Oakton Street, increasing the parking supply, widening sidewalks for streetscape, and enhancing the appearance of the corridor. GHA conducted an extensive data collection effort within downtown to provide the Village with the most accurate and complete picture of traffic flow within the study area. Intersection turning movement counts were collected at 24 locations and daily traffic volumes were collected on 35 roadway segments in November of 2009. GHA prepared five schematic design concepts for Oakton Street which were presented to Village staff. After these consultations, a preferred design concept was identified that would reduce the number of travel lanes along Oakton Street from four through lanes to two through lanes and expand the space for street parking. The preferred concept provides two 12-foot wide travel lanes and a center left turning lane, as well as plans for a new traffic signal to be installed at Floral Avenue. This lane treatment will allow the number of parallel parking spaces along Oakton Street to expand. Using the collected traffic data and preferred roadway design, GHA developed a detailed SYNCHRO traffic simulation model of the study area to evaluate if Oakton Street could satisfactorily accommodate existing and future traffic volumes with the reduced roadway capacity. Other streets in the Village were also analyzed to determine if sufficient capacity exists to accommodate additional traffic should some motorists elect alternate routes as a result of the new road configuration. Based upon the SYNCHRO analysis, GHA anticipates the new Road Diet configuration will result in the following outcomes: 67 additional parking spaces along the corridor, an increase of 117% from the existing 57 on-street parking spaces. An additional 12,100 square feet (a 31% increase) of sidewalk area for enhanced pedestrian mobility, streetscape, outdoor seating, and other public amenities. During the evening peak period, a projected increase in travel time through the corridor of only 27 seconds per vehicle in 2020, provided that traffic signals along the corridor are retimed to improve traffic flow and approximately 30% of the thru-traffic currently using Oakton Street selects alternate routes. It is anticipated that very few motorists would need or elect to find alternate routes during other portions of the day and evenings and on weekends.

The reduced number of through lanes will somewhat reduce travel speeds, but will enhance operational safety along Oakton Street, such as making on-street parking maneuvers for store patrons easier to negotiate. Traffic volumes on neighboring streets such as Central Avenue, Howard Street, Skokie Boulevard, Main Street, and Gross Point Road may increase somewhat, particularly during the evening peak period. However, these streets have sufficient capacity to accommodate the anticipated additional traffic volumes. The estimated cost of the Oakton Street project is $6.3 million dollars. Should the Village wish to continue with development of a preliminary engineering design for Oakton Street, GHA recommends the Village take the following initial actions to move forward with the proposed project: Begin discussions with the Cook County Highway Department, who has jurisdiction of Oakton Street, to determine appropriate steps to implement the corridor modifications. Begin the preparation of civil engineering design plans and Intersections Design Studies (IDS). Oakton Street Corridor Study Executive Summary May 28, 2010 pg. ii

Downtown Skokie & Oakton Street Corridor Study May 28th, 2010 1) Overview of Study In 2009 the Village of Skokie retained Gewalt Hamilton Associates, Inc. (GHA) to study traffic patterns on Oakton Street and adjacent roadways within the Skokie Central Business District. The Village requested the study to determine if Oakton Street would be a good candidate for a Road Diet of the existing four lane roadway between Park Avenue and Skokie Boulevard. Potential benefits of a Road Diet to the Village include: o Traffic calming Replacing the current four-lane roadway with a three lane roadway has traffic calming benefits by reduction of travel speeds resulting in a safer, more pedestrian friendly environment. o Increased convenient on-street parking Reducing the number of vehicle travel lanes would enhance the retail environment for area businesses by providing additional opportunities for on-street parking within the corridor. o Public sidewalks Provide wider sidewalks allowing more room for pedestrian movement and outdoor activities such as dining and seating. o Increase retail visibility by moving vehicles further from building frontages. o Aesthetic enhancements Streetscape enhancements Adding such amenities as decorative pavers, lighting and other urban realm improvements would have a positive impact on the character of Downtown Skokie. Components of this study included collecting traffic and parking data and forecasting future 2020 volumes for a number of geometric scenarios to determine what improvements were feasible. We anticipate that modifications to this section of Oakton Street will change traffic volumes and patterns on the adjacent street network. GHA estimated how much traffic would need to be diverted from Oakton Street to make any given roadway design operate satisfactorily. 2) Oakton Street 2009-2010 Traffic Volumes and Existing Geometrics Existing 2009-2010 Traffic Volumes GHA conducted Hi-Star (machine) counts at 35 locations on November 17 th, 2009 collecting 24- hour traffic volumes on Downtown roadways. Manual turning movement counts were conducted at 24 intersections for the weekday AM peak period (7-9AM) and the weekday PM peak period (4-6PM). The Saturday midday peak period was also counted between 11 AM and 1 PM. Exhibit 1 shows the location of all automatic and manual counts. Manual intersection counts were conducted between November 9 th and November 21, 2009. No adverse weather or other conditions such as construction were present to affect traffic counting operations. Gewalt Hamilton Associates, Inc. Page 3

Downtown Skokie & Oakton Street Corridor Study May 28th, 2010 Using this data and our field observations GHA determined that the weekday PM peak hour period was between 5-6 PM. Traffic was also very congested during this time. The congestion was caused by the increased volumes and other observed street activities such as: Motorists entering and leaving on-street parking stalls. Bus movements and stops, specifically CTA Route 97, Pace Route 210, and Pace Route 226. (Note: Pace Route 210 had weekday service reduced on February 8, 2010.) Pedestrian activity, especially at Oakton Street at Lincoln Avenue. Traffic signals at Oakton Street at Lincoln Avenue, Niles Avenue, Lacrosse Avenue and Skokie Boulevard are not properly coordinated along Oakton Street. This free operation of signals can cause motorists come to a full stop at each of the 4 signals consecutively. The CTA Yellow Line (also known as the Skokie Swift ) has an at-grade rail crossing just west of Skokie Boulevard which causes traffic congestion during the PM Peak. The existing AM, PM, and weekend peak hour traffic volumes at major intersections are shown in Exhibits 2, 3 & 4, respectively. The daily traffic volume counts recorded within the study area are shown in Exhibit 5. Existing Roadway Geometrics Existing roadway geometrics along Oakton Street include left-turn lanes at all signalized intersections, two through lanes in each direction, and on-street parking on both sides of the roadway. Several intersections have pedestrian bump outs to minimize walking distances across Oakton Street. Traffic signals are provided with left-turn arrows east and westbound. Signal jurisdictions are as follows: Signal Location Oakton Street at Lincoln Avenue Oakton Street at Niles Avenue Oakton Street at LaCrosse Avenue Oakton Street at Skokie Boulevard Signal Jurisdiction Village of Skokie maintained Cook County Highway Department (CCHD) maintained Cook County Highway Department (CCHD) maintained Illinois Department of Transportation (IDOT) maintained Gewalt Hamilton Associates, Inc.

3) Preliminary Oakton Street Geometric Design Options Downtown Skokie & Oakton Street Corridor Study May 28th, 2010 GHA prepared five (5) preliminary roadway configurations to investigate the feasibility of various roadway designs that would increase the supply of on-street parking and reduce the number of travel lanes within the study area. Exhibit 6A and Exhibit 6B illustrate the preliminary roadway designs that were developed and presented to Village staff for evaluation and review. The discussions which occurred in our work meetings generated pertinent comments including: It would be difficult to achieve enough sidewalk width to provide enhanced walkabilty without decreasing the number of travel lanes on Oakton Street. It would also be difficult to provide additional sidewalk width with any of the options that have angled parking on the south side. (Option 1, Option 4 & Option 5) The 750 foot spacing of the three existing traffic signals on Oakton Street at Lincoln Avenue / Niles Center Road, Niles Avenue, and LaCrosse Avenue provide excellent spacing for pedestrian crossings. Parking maneuvers would be more efficient if the adjacent travel lanes on Oakton Street were wider than the current (approximate) 10-foot lane widths. All options indicate that the Oakton Street approaches at the Lincoln Avenue / Niles Center Road intersection require a separate left turn lane, a separate through lane, and either a separate right turn lane or a shared through / right turn lane. The two options that provide back-in angle parking create lane shifts that would be more difficult for motorists trying to navigate and familiarize themselves with the area. (Option 4 & Option 5) Key Finding. Based on the five geometric options reviewed along with the constraints of the existing conditions, it was determined that Option 2 was the preferred roadway configuration to be further analyzed for feasibility of a road diet. 4) Preferred Oakton Street Geometric Design (Option 2) Option 2 was selected as the preferred design to undergo additional refinement and analysis for several reasons: Option 2 provides the most additional prime parking along Oakton Street, (67 Spaces). The Village prefers that any roadway modifications design begin at Park Avenue on the west end of the corridor This will ensure that lane transitions will begin before access drives for the Skokie Public Library. Gewalt Hamilton Associates, Inc. Page 5

Downtown Skokie & Oakton Street Corridor Study May 28th, 2010 The Village requested an additional signal at Floral Avenue be included in the design. Parallel parking spaces on both sides of Oakton Street will provide convenient parking opportunities for motorists traveling in both directions of Oakton Street. Option 2 provides the most additional sidewalk area throughout the entire corridor. There is approximately 38,600 SF of existing sidewalk between Lincoln Avenue on the west and LaCrosse Avenue on the east. The preferred Option 2 adds 12,100 square feet of sidewalk for a total of 50,700 Square feet, an increase of 31%. Option 2 provides 12-foot travel lanes, which allow for easier parking maneuverability. The 3-lane pavement width affords the opportunity for larger bump-outs at intersections, which reduces the distance for pedestrians crossing Oakton Street. The center turn lane throughout the corridor provides safe harbor for left turning vehicles at all street and driveway intersections. It can serve as a temporary bypass lane, should a vehicle be stopped momentarily during a parking maneuver. Exhibit 7& Exhibit 8 illustrate the two potential phasing schemes for Option 2. It was determined through discussions with Village staff that it would be beneficial to develop a design that did not affect the CTA Yellow Line railroad crossing at the east end of the Oakton Street corridor. Any street improvements that impact railroad crossings require a lengthy period of review and permitting from the Interstate Commerce Commission. Option 2A This option would begin roadway improvements east of the CTA Yellow Line Railroad Crossing. The option would drop one of the existing westbound thru lanes into a rightturn only lane at the intersection of Skokie Boulevard and Oakton Street. Option 2B (Preferred) This option would implement the lane reduction west of the intersection of Oakton Street and Lacrosse Avenue. It would provide additional merging time for vehicles after passing through the traffic signal and CTA yellow line tracks at the intersection of Skokie Boulevard and Oakton Street. 5) Oakton 2020 Projected Traffic Volumes Based on the preferred geometric plan, Option 2B, traffic volume projections for the evening peak hour were developed for the year 2020. Exhibit 9 shows the projected 2020 traffic volumes within the study area. The scenario is based upon a 1% traffic growth rate through the corridor from 2010 traffic volumes and the future build out of the Illinois Science + Technology development. Gewalt Hamilton Associates, Inc. Page 6

Downtown Skokie & Oakton Street Corridor Study May 28th, 2010 6) Corridor Travel Time & Queue Analysis Corridor Travel Time Analysis Based on the projected 2020 traffic volumes and the reconfiguration of Oakton Street into a three lane section (Option 2B), projected 2020 travel times for vehicles utilizing the corridor were developed. This analysis provides a snapshot of how much delay a motorist would be expected to experience if the roadway was reconfigured from the existing five lane section to a three lane section at the signalized intersections. GHA utilized SYNCHRO simulation software and timed the movement of cars through the corridor. Exhibit 10 shows the anticipated travel delay in seconds. Pertinent observations include: 1) Travel delay through the corridor is expected to increase slightly through the corridor as a result of traffic growth. Between 2010 and 2020, an increase in travel time of 12 seconds in the eastbound direction and 41 seconds in the westbound direction is estimated in no geometric changes are made along the corridor. 2) A portion of vehicle traffic, estimated at 30%, will likely find alternative routes to Oakton Street if the roadway is reduced to a three lane section. 3) With coordination of the signals and 30% of traffic using alternate routes, travel time through the corridor is estimated to increase from 2010 travel times by 39 seconds in the eastbound direction and 36 seconds in the westbound direction during PM peak period. Projected traffic volumes can still be accommodated during other periods of the day without vehicles using alternate routes Queue Analysis Exhibits 11-15 indicate the anticipated queue lengths at the intersection approaches within the corridor for existing and future scenarios. A queue is the distance of roadway that a vehicles occupies while waiting to pass through a signalized intersection. Twenty-five feet of space per vehicle is typically used as an estimate. Thus, a queue of 100 feet would be four cars long. Exhibit 11 shows the existing AM and PM peak hour queue lengths at intersections within the corridor. Exhibit 12 shows the maximum PM queue lengths anticipated after a Road Diet configuration in 2020. This represents a worst case scenario if all motorists were to utilize Oakton Street as they currently do. In order for a Road Diet to operate satisfactorily, a percentage of vehicle travel is expected to utilize adjacent roadways to compensate for the loss of roadway capacity caused by the street s reconfiguration. This diversion of traffic is typical during construction projects, where motorists adjust their travel patterns to compensate for the loss of capacity caused by lane closures. In the case of a road diet, a permanent loss of roadway capacity would encourage some motorists to develop alternate routes which do have sufficient capacity to carry the increase in traffic. Gewalt Hamilton Associates, Inc. Page 7

Downtown Skokie & Oakton Street Corridor Study May 28th, 2010 GHA developed three simulations where a portion of the corridor s projected 2020 traffic was diverted onto adjacent roadways. As more traffic was diverted, the queue lengths at intersections within the corridor were minimized. Exhibits 13, Exhibit 14 and Exhibit 15 indicate when 15%, 25% and 30% of the corridor s traffic uses alternate routes The exhibits indicate that as motorist utilize other roadways, the queue lengths at most approaches become shorter or can be accommodated. 7) Impact on Surrounding Roadways Exhibit 16 shows the traffic volume adjustments anticipated if Oakton Street were to undergo a Road Diet. Based on the SYNCHRO analysis, 230 to 270 motorist are anticipated to use adjacent roadways during the PM peak hour. To determine the roadway capacity each adjacent road had available for additional traffic, a Level of Service of D (LOS D) was assumed. Level of Service (LOS) is a quantitative measure that describes traffic conditions in terms of speed, travel time, freedom to maneuver, and safety. Six classifications are used to define LOS, designated by the letters A through F. LOS A represents the best conditions, while LOS F represents heavily congested traffic flow with traffic demand exceeding roadway capacity. LOS D represents normal traffic conditions in the Chicago region during peak travel times. An additional analysis was conducted to determine if sufficient capacity exists on the adjacent roadways to handle the projected increase in Average Daily Traffic. It is anticipated that reducing the capacity of Oakton Street will add 700-800 trips to adjacent roadways during average days. Our analysis confirms that the adjacent roadway system has sufficient capacity and can accommodate the existing and projected traffic including the vehicles seeking alternate routes as a result of the Oakton Street Option 2B implementation. These roadways will operate at LOS D or better. The following roadways are anticipated to receive higher volumes of traffic: Gross Point Road Central Road Howard Street Main Street Skokie Boulevard Exhibit 17 provides a comparison of Oakton Street with main streets in neighboring Chicago communities. The exhibit demonstrates that a wide variety of roadway configurations can accommodate on-street parking with volumes similar to those along Oakton Street. The corridor is similar in length and scale to many other urban main streets in the Chicago region. Several of those two and three lane streets have significantly higher traffic volumes and provide street parking. Gewalt Hamilton Associates, Inc. Page 8

Downtown Skokie & Oakton Street Corridor Study May 28th, 2010 8) Parking Analysis 2006 Parking Supply and Deficit Study In 2006, the Village of Skokie Engineering Division conducted an analysis of the CX Core Mixeduse (Downtown) Zoning District. The study included a systematic inventory of all Downtown businesses and parking areas. Based on the various land uses located Downtown and parking ratios for each individual land use, parking surpluses or deficits for blocks of downtown were identified. Exhibit 18 provides a detailed breakdown of the Downtown parking supply. Exhibit 19 shows the parking surplus / deficit calculated by the study. Pertinent observations for the 2006 study include the following: 3 of the 12 zones of parking were found to have a parking deficit. The parking deficit within the three zones was a total of 61 spaces. Insufficient parking was identified along the south side of Oakton Street between Lamon Avenue and LaCrosse Avenue (Zone 8); between Niles Avenue and Lamon Avenue along the south side of Oakton Street (Zone 9); and the west side of Lincoln Avenue south of Oakton Street (Zone 12). Parking Occupancy Study #1 (GHA) GHA conducted a parking occupancy survey of the Downtown during the week of November 16 th, 2009. GHA observed parking occupancies to determine how capacity requirements changed throughout the day as user groups parking requirements changed. Exhibit 20 shows the resulting parking occupancies for on-street and off-street parking areas. Study observations include: The peak combined occupancy for on-street and off-street parking occurred on the weekday from 3:00 P.M. to 4:00 PM with 47% occupied. For on-street parking, the peak occupancy was reached during the weekend (November 21, 2009) at Noon 12:00 PM with 47% Occupied. For off-street parking, the peak occupancy was reached at 49% from 3:00 to 4:00 P.M. during the weekday. In addition, GHA staff observations during the course of the study highlighted additional parking concerns in the study area including the following: Parallel parking on both Oakton Street and Lincoln Avenue has the appearance of being narrow due to the width of travel lanes on Oakton Street. Gewalt Hamilton Associates, Inc. Page 9

Downtown Skokie & Oakton Street Corridor Study May 28th, 2010 Parallel parking maneuvers are often difficult on side streets such as Babb Avenue, Niles Avenue, and Lamon Avenue due to traffic and turns from side roads onto Oakton Street. Parking lots by Lincoln Jr. High School (Babb Avenue & Louise Avenue) are poorly marked; some are private and some are public, but are hard to determine with existing signage. Parking maneuvers are difficult at the Brown Street and Lincoln Avenue/Niles Center Road split because of the unique signal phasing at the intersection. Traffic into and out of Walgreens and the adjacent public lot to the east creates parking hazards on the north side of Oakton Street at LaCrosse Avenue. Parking Occupancy Study #2 (Tyler Roberts) The Village commissioned a second study in January 2010 to assess parking in the Downtown. The study split Downtown into six different zones of parking, and a detailed occupancy study of public and private on-street and off-street parking in each zone was conducted. Exhibit 21 shows the location of the Downtown parking areas surveyed. Parking areas were surveyed on two weekdays and one weekend in January 2010. Exhibit 22 provides the occupancy analysis for the peak day of occupancy observed during the study. Observations from the January 2010 study include the following: Peak occupancy of the study area occurred on the weekday at 2 PM with 45% of the surveyed spaces occupied. Areas B, D, and E had occupancies of 60% to 90%, indicating that these areas were more heavily utilized. The Parking lot located at 4830 Oakton Street was heavily occupied during the study period. It is our understanding that the lot is used by employees, particularly employees of the Science + Technology Park. Parking areas along LaCrosse Avenue, Lamon Avenue, and Niles Avenue south of Oakton Street were over 60% occupied during the study period. Parking Study Discussion Drivers tend to perceive parking to be at capacity when 80%-85% of the spaces are occupied. This causes drivers to circulate to find a parking space and contributes to greater traffic in the area. In general, if a motorist cannot find a parking space within the first or second pass of a business, the motorist will perceive that parking is insufficient in the area, particularly in business or shopping areas. Based on the results of the above referenced studies, Downtown Skokie has a sufficient supply of parking within Downtown. Both recent occupancy studies indicated peak occupancy in the downtown is between 45%-47% of the available supply of parking, which is well below what is considered full. Despite this, several hotspots where parking is deficient or perceived to be deficient are located within the study area, primarily along Oakton Street. For example, the on- Gewalt Hamilton Associates, Inc. Page 10

Downtown Skokie & Oakton Street Corridor Study May 28th, 2010 street spaces that support the businesses on the south side were over 80% occupied on the weekend. Thus, motorists traveling eastbound on Oakton Street could perceive that parking is not available and perhaps decide not to stop. Roadway geometry can also have a significant impact on motorist s perceptions of parking availability. Even if area parking is plentiful, the combination of narrow travel lanes next to the parallel parking spaces and having to be mindful of four lanes of moving traffic can make parallel parking maneuvers uncomfortable for motorists. 9) Streetscape Visual Simulations Exhibit 23 shows two streetscape character simulations developed to graphically portray the proposed streetscape improvements along Oakton Street: A west view of the current conditions at Babb Avenue was overlaid with the proposed threelane cross section, wider sidewalks, and other sidewalk amenities. An east view of the current conditions at Lamon Avenue was overlaid in a similar way to Babb Avenue. 10) Concluding Remarks The Village of Skokie is working diligently toward revitalizing its Downtown. Recent years have seen new mixed-use residential developments built and business facade improvements funded to enhance the visual character of the Downtown. Unfortunately, like many other communities during this economic downturn, Skokie has seen many Downtown businesses, particularly along Oakton Street, have difficulty meeting the challenge of a recession. An important recent market study commissioned by the Village set a framework for maintaining the stability of existing businesses and attracting new ones. A recommendation from that study detailed the need for the Village to provide more prime customer parking along Oakton Street and in small convenient lots, and improvements to enhance the pedestrian environment we are also recommending. To this end, Gewalt Hamilton Associates, Inc. (GHA) was retained to conduct a transportation planning study throughout downtown Skokie with a general focus along the Oakton Street corridor. It was determined early in our study that perhaps the only way to achieve the dual goals of providing more on-street parking and wider sidewalks was to put Oakton on a Road Diet. This technique has worked well for other communities who have a similar vision as the Village of Skokie - to provide a pleasant environment for pedestrians without sacrificing traffic mobility. Gewalt Hamilton Associates, Inc. Page 11

Downtown Skokie & Oakton Street Corridor Study May 28th, 2010 The results of our study are summarized briefly below: Geometric Options Converting Oakton Street from a 4-5 lane road to a 3-lane street will provide wider sidewalks throughout the corridor. Wider sidewalks could attract cafes with plaza seating, encourage outdoor displays / sales, and perhaps promote entertainment opportunities. The 3-lane street section would be to provide an estimated 67 additional prime on-street parking spaces. This would more than double the existing 57 on-street spaces within the corridor. Traffic Impacts A very detailed Synchro traffic model was developed to test and visualize the travel impacts within Downtown should Oakton Street be put on a Road Diet by reducing the number of through lanes on Oakton Street. The testing concluded that about 30% of the current through traffic volumes would have to use alternate routes to achieve similar travel times along Oakton. This reduction in volumes was needed during the weekday evening peak period. It was not necessary for the weekday morning or weekend midday peak periods. Shifting 30% of the weekday evening through traffic to other streets can be accomplished without overburdening the surrounding streets or alternative routes. Sufficient reserve capacity is available to maintain acceptable operations on streets such as Main Street, Howard Street, Skokie Boulevard, and Central Avenue. The 30% traffic reduction will be achieved by motorists selecting alternative routes as congestion increases. Parking The detailed parking studies conducted by the Village conclude that there is plentiful supply in off-street parking lots in Downtown Skokie; however, many of those lots are small and not easy to find. The Village Downtown Market Study concluded the supply of convenient on street parking spaces were insufficient and should be increased. The Village parking study and the data collected by GHA agree with the Market study that the parking needs to be improved. A increase in prime customer parking along Oakton Street is necessary to improve retail activity in the Oakton Street Downtown corridor. Gewalt Hamilton Associates, Inc. Page 12

Downtown Skokie & Oakton Street Corridor Study May 28th, 2010 Recommendations GHA recommends that the Village proceed with the recommended Option #2B modifications to the Oakton Street Corridor based on the study results and numerous benefits that the improvements will provide that the Village desires. GHA recommends that the improvements be phased to speed the implementation process and to reduce upfront costs. The first phase should be the construction of improvements from Park Avenue to Lacrosse Avenue (Option 2B). The second phase should be the modification of Oakton Street east of Skokie Boulevard to improve the transition of traffic into the Downtown. Project Implementation Public presentation of the report to the Village Board to obtain direction as to the implementation of the recommended improvements. A presentation to Downtown merchants should be conducted to determine support from local businesses. A preliminary cost estimate of the desired option should be prepared. A test of the recommended option should be conducted to determine if desired traffic movements are achieved and expected diversion of through traffic occurs. Modifications can be made to the final plan prior to the preparation of engineering plans. Start the preparation of Intersection Design Studies (IDS) for affected intersections. Meet with Illinois Department of Transportation and Cook County Highway Department officials to determine the steps necessary to implement the corridor modifications. Gewalt Hamilton Associates, Inc.
