To: Chuck Schneider Burlington S&S, LLC 225 West Washington Street Indianapolis, IN 46204 From: Patrick Dunford, P.E. Senior Project Manager Date: April 3, 2018 Revised May 15, 2018 Project #: 13482.01 Re: Burlington Mall Retail Collection Transportation Evaluation Burlington S&S, LLC (the Proponent) is proposing to reposition portions of the Burlington Mall (the Project) located on in Burlington, Massachusetts (the Site ). Specifically, the Proponent is seeking to redevelop the former Sears Auto Center ( TBA ) building to include a mixture of restaurant and retail uses. This work also will involve minor Site revisions to accommodate new outdoor dining areas and improvements to the Site layout, parking, and access. The building space recently occupied by the Sears anchor store at the northern end of the Burlington Mall also is planned to be redeveloped to include a similar mixture of retail and restaurant space. The following memorandum summarizes the potential changes in traffic generation associated with the Project and evaluates potential Project impacts. Existing Conditions In total, the Burlington Mall currently contains 1,591,024 square feet (sf) of total physical building area, including the currently vacant Sears TBA outparcel building. This building area includes leasable space for a variety of tenants, as well as common space, mechanical rooms, and other non-leasable area used for the general operation of the mall. The parking needs for the mall are currently accommodated by approximately 5,573 on-site parking spaces. Burlington Mall Site Access Access to the mall currently is provided by multiple driveways on the abutting roads. A full-access signalized driveway is located at the approximate midpoint of the property s frontage. A right-turn, enter-only driveway is located immediately south of the signal, and a driveway restricted to entering/exiting right-turns only is located roughly 850 north of the signal (and 400 feet to the south of Burlington Mall Road). Two separate signalized driveways are provided on Burlington Mall Road. The first is located approximately 800 feet to the east of Middlesex Turnpike. The mall driveway is slightly offset from Meadow Road on the opposite side of the roadway, with both approaches operating under the same signal controller. Approximately 750 feet further to the east, Burlington Mall Road is intersected by the mall driveway from the south and Lexington Street from the north. Sears TBA Access The currently vacant Sears TBA building is located at the northwest corner of the overall Burlington Mall property. This parcel also is located at the southwest corner of Burlington Mall Road s signalized intersection with the mall driveway opposite Meadow Road. Extending to the south from Burlington Mall Road, the mall driveway features two lanes in each direction separated by an approximately eight-foot wide landscaped median. Access to the former Sears TBA parcel currently is provided by a full-access unsignalized driveway intersecting the median-divided mall driveway approximately 195 feet to the south of Burlington Mall Road. Access to this parcel also is provided via two driveways on the mall east/west circulation aisle extending from to the median-divided mall driveway noted above. The first driveway is located just west of the above-mentioned drive aisle, and a second driveway is located 135 feet to the west of that. \\MAWALD\ld\13482.01 Simon Burlington\docs\memos\Traffic evaluation - revised.docx
Ref: 13482.01 May 15, 2018 Page 2 Proposed Project The proposed Project will involve the redevelopment of the vacant Sears TBA building, and the reoccupancy of recently-vacated building space previously occupied by the Sears anchor store. The following sections summarize the proposed Project components. Sears TBA The currently vacant Sears TBA building contains 28,460 sf of former auto-service/retail space, with an additional 19,756 sf of below-grade storage space. In total, the building contains a combined 48,216 sf of leasable building area. The development proposal involves the existing TBA building being redeveloped as approximately 35,000 sf of total outparcel building space to be occupied by retail/restaurant uses. Current plans call for approximately nine retail tenant spaces and five restaurants, generally to be positioned at the corners of the building. Of the 35,000 sf of total building area, these restaurants will occupy 11,337 sf of building area and will include 316 seats with an additional 157 patio seats. The remainder of the building will be used for approximately 21,831 sf of leasable retail space, with additional space to be used for storage, mechanical space, etc. Sears anchor store repositioning The repositioning of the former first-floor Sears anchor store space will consist of retenanting that space to include a mixture of retail and restaurant space. This work will involve improvements to the exterior of the building and sidewalk areas, which also will allow for outdoor patio restaurant seating. Following this work, there will be roughly 39,011 sf of restaurant space provided including 1,107 seats (and an additional 335 outdoor patio restaurant seats). The remainder of the former Sears space will be occupied by multiple retail tenants with a total gross leasable area (GLA) of 74,774 sf. A 5,365-sf section of the northeasterly end of the Sears building will be demolished to allow for this and other landscape amenity space. The upper story space including the Primark tenant space will remain unchanged. With the former Sears space being replaced by multiple smaller stores and restaurants occupying the former Sears space, there now will be newly-created common space serving these individual tenants similar to that which exists throughout the rest of the mall. Accordingly, there now will be multiple tenants within the former Sears footprint, but with a reduced total leasable area due to the introduction of this common space. In total, the mall currently has 1,328,821 sf of gross leasable area (GLA). This includes the former 48,216 sf of TBA building area, approximately 4,000 sf of sales carts currently located within the main hallways of the mall, and multiple retail and restaurant tenants (including associated stockrooms and supporting leasable space). Table 1 provides an overall summary in the proposed changes to the mall categorized by the newly created uses and associated changes to the existing Burlington Mall. \\MAWALD\ld\13482.01 Simon Burlington\docs\memos\Traffic evaluation - revised.docx

Ref: 13482.01 May 15, 2018 Page 4 As shown in Table 1, the Project will result in an overall 19,691 sf reduction in the total building area at the Burlington Mall. Furthermore, the 1,328,821 sf of total mall leasable area will decrease to 1,280,019 sf GLA with the Project; a reduction of approximately 48,802 sf. The following sections discuss how traffic generation was estimated for the Project considering this reduction, as well as the new uses proposed within the Site. Trip Generation Potential traffic increases associated with the Project were estimated using standard Institute of Transportation Engineers (ITE) data 1, considering the difference between the existing and proposed Burlington Mall building area and uses. The following sections discuss the three different methodologies considered for this analysis to estimate the potential changes in Project trip generation. Method 1 ITE Shopping Center With the overall reduction in building area it reasonably could be assumed that there will be a corresponding reduction in trip generation. However, to provide for a conservative analysis, trip generation was evaluated also considering the unique nature of the former Sears TBA use. While the Project will revitalize and renovate a significant portion of the mall, the Burlington Mall still will remain as a standard regional shopping center, though one with an increased amount of restaurant space. Therefore, the trip generation for the proposed conditions was compared to the current Burlington Mall using ITE Shopping Center data consistent with industry practices. The definition for this ITE land use code notes that shopping centers can include retail, restaurant, and other uses, as well as outparcel developments similar to that present at the Burlington Mall. ITE also notes that trip generation should be estimated based on the gross leasable area of the mall, and not including common areas, mechanical rooms, etc. For this analysis, trip generation for the former Sears TBA use was calculated separately using ITE data independent from the remaining overall Burlington Mall Shopping Center space. The resulting change in trip generation for the overall Burlington Mall using this methodology is shown in Table 2. 1 Trip Generation Manual (10 th edition), Institute of Transportation Engineers, Washington DC, 2017. \\MAWALD\ld\13482.01 Simon Burlington\docs\memos\Traffic evaluation - revised.docx

Land Use Code 942 (Automobile Care Center). Trip generation data not available for Saturday midday peak hour. Trip generation during this time period is assumed to be equal to that during the weekday evening peak hour. The proposed Project involves a 48,802 sf reduction in tenant leasable area. With that reduction in GLA there should be a corresponding reduction in trip generation. As shown in Table 2, the total traffic generated by the Site should be reduced by 129 trips during both the weekday evening and Saturday midday peak hours. This procedure follows industry standards for estimating shopping center traffic generation, and is the most reasonable means of estimating trip generation as it also considers the former TBA use as a separate entity. While the Project involves the introduction of new restaurant space, it will not change the overall function of the Burlington Mall as a regional shopping center. The proposed new mixture of casual and finer dining establishments can be found at any shopping mall, and are consistent with the current and former use of the Site. In addition to the \\MAWALD\ld\13482.01 Simon Burlington\docs\memos\Traffic evaluation - revised.docx
Ref: 13482.01 May 15, 2018 Page 6 food court area, the mall already includes multiple restaurants, and until recently also included a Pizzeria Uno and Rainforest Café. The new restaurant space proposed as part of this Project will represent only four-percent of the total GLA in the Burlington Mall, so the overall dynamic of the mall will not be changing significantly. Method 2 ITE Shopping Center Retail and Restaurant (Building Area) Components VHB also evaluated trip generation using an alternate procedure focusing on the increase in restaurant building space. While the Burlington Mall still clearly meets the ITE definition of a Shopping Center under proposed conditions, the increased amount of restaurant space was considered separately for this exercise. The existing restaurant space within the mall will remain unchanged, but the additional restaurant space proposed was estimated as an overall new entity. Specifically, for the proposed condition the changes in retail and restaurant building space were considered separately, with the resulting difference being compared to the existing Burlington Mall. A detailed description of each step in this process is provided as follows. Method 2 Retail As shown earlier in Table 1, the amount of leasable retail space within the Site (not including the former TBA use) will be reduced by 50,935 sf. With that reduction, there will be a corresponding reduction in retail trips, but that area will be replaced by new restaurant space generating traffic as discussed in the following section. Method 2 Restaurants Exact tenants for each of the new multiple restaurant tenant spaces are currently not known. However, based on information provided by mall ownership, approximately 75-percent of the new restaurant space is being marketed towards casual restaurant uses, with the remaining 25-percent of the leasable area devoted to more formal, finer dining establishments. To account for this mixture of restaurant styles, trip generation estimates for the new restaurant components were based on ITE data for a standard High-Turnover (Sit-Down) Restaurant. ITE also recently added a new Fast Casual Restaurant land use code which has a definition similar to the style of restaurants proposed. However, that ITE database is very limited, with only three studies available for Saturday midday peak hour conditions. Accordingly, trip generation for 75-percent of the planned restaurant space was based on the ITE High-Turnover (Sit- Down) Restaurant land use code. The remaining 25-percent of the leasable restaurant space is expected to be more formal in nature, similar to the ITE Quality Restaurant land-use description. Trip Sharing Use of the ITE Shopping Center land use code is the most appropriate means of estimating mall traffic as it accounts for the internal trip sharing that is inherent to any regional shopping center. The ITE data shows that external trip generation rates decrease as a mall s size increases. This is due to the increased internal trip sharing that occurs between the multiple businesses within a given site. In this instance, the new restaurant space will simply be another attraction to mall shoppers and will not function as an entirely new, independent entity. The restaurants obviously will attract new visitors to the Site, but a substantial portion of the restaurant patrons already will be visiting the Site as shoppers. These trips will occur as walking trips within the mall, or between the mall and redeveloped Sears TBA building, but will not show up as additional vehicle trips at the Site driveways or on the adjacent streets. \\MAWALD\ld\13482.01 Simon Burlington\docs\memos\Traffic evaluation - revised.docx
Ref: 13482.01 May 15, 2018 Page 7 If the new restaurant space is to be considered separately, it is important that this internal trip sharing be quantified. ITE 2 has an established methodology for estimating trip generation for scenarios where two or more distinct land uses exist on a site. The ITE database includes trip sharing data between multiple land uses including retail and restaurant for peak-hour conditions. The percent of retail customers that may visit a restaurant after shopping is summarized, as well as diners than may shop before leaving the site. For instance, the ITE database indicates that half of restaurant patrons may shop after dining as part of their same trip before leaving the site. Similar interactions also will occur involving shoppers dining before or after shopping as part of their primary purpose for being on Site. The results of the trip generation estimates based on the proposed retail and restaurant components being considered separately (Method 2) are summarized in Table 3. 2 Trip Generation Handbook 3 rd edition, Institute of Transportation Engineers, Washington DC, 2017. \\MAWALD\ld\13482.01 Simon Burlington\docs\memos\Traffic evaluation - revised.docx

As shown in Table 4, even considering the new restaurant uses separately from the retail space, there still will be a reduction in external trips appearing at the Site driveways. Specifically, the Project should result in a decrease of 110 and 112 trips during the respective weekday evening and Saturday midday peak hours. However, the Project is expected to increase the interaction between the restaurants and other retail space within the Site in the form of internal pedestrian activity. As with existing conditions, not all of the external traffic generated by the Project will be new to the area roadways. For example, a portion of the external vehicle-trips generated by the retail and restaurant uses likely will be drawn from traffic already travelling past the Site, which is attracted to the new uses as the motorists are passing through the area. The primary origin and destination for these trips is elsewhere and the primary trip will be resumed following the visit to the site. Pass-by rates also are provided by ITE in the Trip Generation Manual. Traffic count and survey data from nationwide retail locations have been collected by ITE for the purposes of pass-by trip calculation. Based on the ITE data, approximately 34- and 26-percent of peak-hour retail traffic on a respective weekday and Saturday is in the form of pass-by trips. Likewise, while Saturday information is not available, ITE indicates that a high-turnover restaurant will have a pass-by rate of approximately 43-percent during the weekday evening peak hour. Method 3 ITE Shopping Center Retail and Restaurant (Seats) Components The final trip generation methodology considered is the same as Method 2, with the exception that the proposed number of new seats was used to estimate restaurant trip generation instead of the associated building area. The resulting trip generation estimates are summarized in Table 5. \\MAWALD\ld\13482.01 Simon Burlington\docs\memos\Traffic evaluation - revised.docx

Table 6 presents the potential changes in Site traffic as estimated considering the total amount of proposed retail space and the number of new restaurant seats. Between the reoccupancy of the former TBA building and vacant Sears space, there will be 1,423 new restaurant seats, and an additional 492 patio seats. As these seats generally would only be in use in warm conditions, the trip generation is conservative in that over 25-percent of the seats incorporated into the analysis would only be in use for part of the year (and not during peak winter holiday shopping conditions). Even with these conservative assumptions, there still would be an overall reduction in trip generation during the weekday evening and Saturday midday peak hours. Based on this methodology, the Project would result in a decrease of 36 and 13 trips during the respective weekday evening and Saturday midday peak hours. Traffic Count / ITE Trip Generation Comparison VHB previously had conducted traffic counts of the Burlington Mall site driveways in November 2013. These counts were conducted as part of the Draft Environmental Impact Report prepared for the nearby New England Executive Park development project. The count sheets are provided for reference in the appendix to this document. A summary of the observed volumes at each driveway are summarized in Table 7. \\MAWALD\ld\13482.01 Simon Burlington\docs\memos\Traffic evaluation - revised.docx

As shown in Table 7, the previously observed weekday evening peak hour driveway volumes at the Burlington Mall were only 60-percent of the levels estimated using ITE data. However, during the Saturday midday peak hour the driveway volumes were approximately 94-percent of the level expected based on the ITE data. Regardless, for consistency, this current study s procedure of estimating trip generation using ITE data for both existing and proposed conditions is appropriate as the same methodology and database is used for both scenarios. With the overall mall trip generation not expected to increase, the trip distribution patterns shown in Table 7 should remain relatively unchanged. The traffic counts indicated that the westerly Burlington Mall Road driveway (opposite Meadow Road) is used by roughly 13-percent of the total Site entering/exiting traffic. Likewise, the Middlesex Turnpike right-in/right-out driveway is used by approximately 6-percent of the overall Site traffic. In conjunction with the 2013 data collection, capacity analyses also were conducted at the Burlington Mall Road/Meadow Road/Sears driveway intersection. The analysis results (provided for reference in the Appendix to this document) indicated that this location was projected to operate at an overall level-of-service (LOS) D during both the weekday evening and Saturday midday peak hours under the 2018 Build condition from that study. This indicates acceptable delays and overall operating conditions could be expected for that condition. The analysis also indicated that all of the entering and exiting movements to and from the mall were expected to operate at the same acceptable LOS D. VHB also recently conducted turning movement counts for this intersection during the midday peak period on Saturday, March 10, 2018. The counts are provided for reference in the appendix to this document, and are generally consistent \\MAWALD\ld\13482.01 Simon Burlington\docs\memos\Traffic evaluation - revised.docx
Ref: 13482.01 May 15, 2018 Page 13 with the previously conducted 2013 traffic counts at this location. Accordingly, with no increase in Site trip generation or notable changes in trip distribution, these same LOS D operating conditions can be expected in conjunction with the Project. Further, this location is part of a recently-installed adaptive signal system along the and Burlington Mall Road. Under this system, each signal operates in a coordinated manner, and also responds to actual traffic conditions on a cycle-by-cycle basis without strictly relying on more rigid pre-established timing plans. This system will be able to readily handle any potential minor changes in arrival/departure patterns to maintain the acceptable LOS D conditions noted earlier. Conclusion VHB has evaluated the potential changes in traffic generation resulting from the repositioning of the Burlington Mall. This assessment considered multiple different methods for estimating potential changes in trip generation. These involved considering the overall reduction in building area resulting from the Project, as well as the somewhat unique former Sears TBA use and the additional restaurant uses being introduced to the Site. Following these industry-accepted methodologies, the Project will result in a reduction in the volume of peak-hour traffic visiting the Site under weekday and Saturday conditions. This conclusion is the same whether the mall is considered as a single overall entity including restaurants (which is the standard industry practice), or if the restaurants are considered separately based on either building area or seating. While the Project will reduce the peak-hour trip generation it is possible that other times of day could see minor increases or changes in patterns resulting from the new restaurants uses. These would most likely occur during the midday lunchtime period, or later into the evening after retail activity already has peaked. A graph depicting the likely hourly distribution of a fast-casual restaurant compared to standard retail uses is provided in the appendix to this document (Figure 1). These minor changes in traffic patterns should be readily accommodated by the primary signalized Site access driveways. The signals at these locations are part of a recently-installed adaptive signal system along the and Burlington Mall Road corridors. With this system, each of the signals operates in a coordinated manner, and now also responds to actual traffic conditions on a cycle-by-cycle basis without strictly relying on more rigid pre-established timing plans. This system will be able to readily handle the minor changes noted above through its ongoing adaptive changes to timings throughout the day. With this infrastructure in place, and the critical peak-hour Project trip generation being reduced, additional off-site analysis or improvements are not necessary. As part of the Project the proponent will be making changes to the mall access drive extending from Burlington Mall Road to the east of the former Sears TBA building. These improvements will involve eliminating the median on this roadway and providing only a single entering lane from Burlington Mall Road into the Site. The existing exclusive leftand right lanes for exiting traffic will remain unchanged so that the overall signal operation will not be affected. A new crosswalk also will be provided across this access aisle immediately south of the Sears TBA curb cut. Improved signage and striping will be provided at the internal four-way, Stop-controlled intersection between Sears and the former Sears TBA building. The existing curbline on the westerly side of this aisle will be shifted to the east by approximately 18-feet, which will provide a more-pedestrian-friendly environment. As noted earlier, the Sears TBA parcel currently \\MAWALD\ld\13482.01 Simon Burlington\docs\memos\Traffic evaluation - revised.docx
Ref: 13482.01 May 15, 2018 Page 14 has two curb cuts on the east/west circulation aisle extending from to the corner of the Sears building. These will be consolidated into a single driveway to be located approximately 120 feet to the west of the four-way Stop intersection noted above. Eliminating the easterly driveway, which is in close proximity to this intersection, will help minimize conflicts at that location. Likewise, the westerly driveway for this parcel currently is slightly offset from another internal mall circulation aisle extending to the south to the main mall parking area. Eliminating that curb cut also should help to improve conditions at that location by eliminating conflicting traffic associated with the Sears TBA redevelopment. \\MAWALD\ld\13482.01 Simon Burlington\docs\memos\Traffic evaluation - revised.docx
