Hancock Associates 315 Elm Street Marlborough, Massachusetts 01752 Subject: Transportation Peer Review Comments—Letter#4 Proposed Dunkin'Donuts Development 1018 Osgood Street—North Andover,MA Dear Mr.Peznola: MDM transportation Consultants, Inc. (MDM) has reviewed the Response to Traffic Review Comments letter dated January 15, 2013 prepared by Greenman-Pedersen,Inc. (GPI) which was provided as a response to MDM's peer review letter of January 4, 2013 for the subject project. We have also received a response letter from MHF Design Consultants, Inc. (MHF) dated January 10, 2013 and have prepared a separate peer review letter dated January 15, 2013. Based on that review, we recommend that the area to the east of the site driveway be re-graded to improve sight distance from 1060 Osgood Street and that a sidewalk be provided along Osgood Street and continue into the site should it not be possible to provide a direct connection between the site and 1060 Osgood Street. With respect to the GPI response letter, MDM has reviewed the supplemental Trip Generation, Drive-Tl-trough Lane Queuing and On-Site Parking information that has been submitted. The following comments summarize our review of these items. TRIP GENERATION GPI has provided weekday morning and Saturday midday trip generation data for the existing Dunkin Donuts at 982 Osgood Street. When compared to the ITE-based trip generation estimate provided in the Traffic Impact and Access Study (TIAS)', the existing Dunkin Donuts store generates 19 less vehicle trips during the weekday morning peak hour and 34 less vehicle trips during the Saturday midday peak hour. While the existing Dunkin Donuts store is smaller iln size and co-located with a full-service gas station, it is expected that these trip generation characteristics will generally transfer to the proposed site with some minor increases Traffic Impact and Access Study;Proposed Dunkin Donuts,North Andover,Massachusetts;prepared by Greenman-Pedersen, Inc.;August 2012 28 Lord Road,Suite 280 •Marlborough,Massachusetts 01752 Phone(508)303-0370•Fax(508)303-0371 •www.mdmtrans.com Mr.Joseph D.Peznola,P.E. January 24,2013 Page: 2 anticipated due to the modern, full-service amenities, additional seating capacity and improved store visibility. As such, the 1-tigher ITE-based trip generation estimate provided in the TIAS (i.e., 255 total vehicle trips during the weekday morning peak hour and 194 total vehicle trips during the Saturday peak hour) appears reasonable for planning purposes. No further review of site trip generation is required at this time. DRIVE-THROUGH LANE QUEUING GPI has provided three estimates from three different sources relative to the drive-through queue lengths projected for the proposed site; 1) a national study indicating a maximum 13- vehicle queue,2) a probability based calculation indicating a maximum 10-vehicle queue,and 3) observations at the drive-through for 982 Osgood Street indicating a maximum 11-vehicle queue. Given the degree that drive-through lane usage fluctuates from month to month and the minor increase in traffic anticipated from the relocation of the store, it is reasonable to expect a maximum 13-vehicle queue in the drive-through lane. This vehicle queue length can be accommodated within the site and is not expected to impact traffic operations along Osgood Street. However, MDM remains concerned with the degree to which parking spaces will be impacted when the drive-through queue exceeds nine vehicles given the limited supply of parking. Based on the drive-through observations reported for 982 Osgood Street, queues in excess of nine vehicles were observed between 7:45 AM and 8:30 AM during the weekday morning peak hour. A similar result will likely occur at the proposed site. Ili order to limit the impact on parking during this time period, GPI states that the two parking spaces closest to the drive- through lane will be designated as employee parking and the third closest space will be designated as an accessible space. However, at times when the drive-through queue reaches 13 vehicles, it is estimated that three additional parking spaces (i.e., six parking spaces in total)will have their access restricted. As discussed below, parking supply remains a concern and the fact that the drive-through queue will block access to several parking spaces only worsens the situation. ON-SITE PARKING In a previous correspondence Z, GPI indicated that 17 parking spaces were occupied at a similar free-standing Dunkin Donuts in Methuen, MA during the Saturday midday period. As such, we believe that the proposed 19 space parking supply will leave little to no reserve capacity during peak hours, and therefore, may not be sufficient for the proposed use. hi their latest 2 Response to Comments; Proposed Dunkin Donuts, North Andover, Massachusetts; prepared by Greenman-Pedersen, Inc.; December 2012 MDM Mr.Joseph D.Peznola,P.E. January 24,2013 Page:3 submission, GPI has provided weekday morning and Saturday midday parking demand counts for the existing Dunkin Donuts at 982 Osgood Street for comparison purposes. The data indicates that 12 out of 19 parking spaces were occupied for a length of time during the weekday morning and Saturday midday peak periods. While it is not clear which parking spaces were vacant,it is clear that many, if not all of the parking spaces located behind the store are extremely inconvenient for patron use and as such, it would not be surprising to learn that many of these spaces were vacant even during peak traffic periods. Never-the-less, we anticipate a greater parking demand at the proposed site due to the additional indoor and outdoor seating capacity proposed. GPI also notes that "parking space observations" were made at three other Dunkin Donut facilities,however,we do not believe that this information is relevant for the following reasons; It appears that GPI has only reported the number of parking spaces provided at these sites and not the actual peak parking usage. It is possible that these sites reach their parking capacity during peak hours. Other area Dunkin Donuts provide 30 parking spaces or more including locations in Methuen,Middleton and Dracut,MA(see attached aerial photos). The Dunkin Donuts located at 5 Ayers Village Road in Methuen, MA appears to provide 48 parking spaces based on the attached aerial photo compared to the 17 spaces reported by GPI. The Dunkin Donuts located at 17 South Broadway in Salem, NH appears to provide 18 parking spaces based on the attached aerial photo compared to the 13 spaces reported by GPI. SUMMARY MDM has reviewed the supplemental Trip Generation, Drive-Through Lane Queuing and On- Site Parking information that has been submitted for the redevelopment of 1018 Osgood Street, Based on this information, we agree that the proposed Dunkin Donuts could generate 255 total vehicle trips during the weekday morning peak hour and 194 total vehicle trips during the Saturday peak hour. We also agree that the proposed drive-through facility could generate a maximum queue of 13 vehicles. However, we remain concerned that the proposed 19 space parking supply will not adequately support the site operation. Mr.Joseph D.Peznola,P.E.

Hancock Associates 315 Elm Street Marlborough,Massachusetts 01752 Subject: Transportation Peer Review Comments—Letter#2 Proposed Dunkin Donuts Development 1018 Osgood Street—North Andover,MA Dear Mr.Peznola: MDM transportation Consultants, Inc. (MDM) has received and reviewed the Response to Comments memorandum dated December 11, 2012 prepared by Greenman-Pedersen,Inc. (GPI) which was provided as a response to MDM's peer review letter of November 9, 2012 for the above project. As you are aware, several items presented in the original TIAS (August 13,2012) for the subject project required further analysis or explanation in order to provide a comprehensive analysis of the project's potential traffic impacts. Based on our review, many of the outstanding issues have been appropriately addressed by the Applicant and do not require further. Issues that require additional clarification or explanation from the Applicant are described below. TRIP GENERATION We believe that the proposed Dunkin Donuts will serve the majority of customers currently patronizing the store at 982 Osgood Street. As such, we recommended that the Applicant collect trip generation and vehicle queuing data from the existing facility as we believe that this is this best data available for estimating peak hour operations at the proposed store. Specifically, trip generation and peak hour drive-thru queue lengths are critical components to the site operations with potential impact on the accessibility to the limit supply of parking spaces proposed. COLLISION HISTORY As recommended by MDM, the Applicant has reviewed additional crash data and has determined that, while there are a relatively high number of accidents occurring in the study area, the collisions do not indicate a particular pattern correctable by engineering measures. 28 Lord Road,Suite 280 •Marlborough,Massachusetts 01752 Phone(508)303-0370 •Fax(508)303-0371 •www.mdmtrans.com Mr.Joseph D.Peznola,P.E. January 4, 2013 Page: 2 Additionally,the Applicant has revised the site driveway layout,has removed a large tree along the site frontage and proposes to clear roadside vegetation to enhance safety for motorists exiting the site. Due to the close proximity of the entrance driveway to 1060 Osgood Street, MDM recommends that the Applicant modify the grading to the east of the proposed entrance driveway(within the State Highway layout) in order to improve sight distance for vehicles exiting from 1060 Osgood Street. DRIVE-THROUGH LANE VEHICLE QUEUING The Applicant has conducted an alternative drive-thru queue analysis which results in a maximum queue of 10 vehicles in the drive-thru lane during the weekday morning peak hour. This estimate is generally based on national trip generation statistics for coffee/donut shops and is not necessarily representative of the drive-flru queues generated by Dunkin Donuts in New England. In addition, the Applicant's prior traffic study indicated a peak vehicle queue of 13 vehicles. The Applicant should explain tl-ds discrepancy and identify measures that will be taken should the drive-thru queue lengths exceed the storage area and impact the on-site parking supply. SITE ACCESS The Applicant has modified the site layout and access design to include one-way counterclockwise circulation in and aromid the site with entrance-only movements at the northern site driveway and egress-only movements at the southern site driveway. MDM generally concurs with the revised site layout and access design and generally concurs that reducing the number of access/egress locations to one entrance-only driveway and one egress- only driveway will mh-iinize vehicular conflicts and provide for more efficient on-site parking flow. MDM also generally concurs with the construction of exclusive turn lanes at the egress driveway which will better accommodate on-site vehicle queues. The Applicant states that the access has been designed to accommodate sidewalk construction along the site frontage should the Town or MassDOT construct sidewalk along the western side of Osgood Street in the future. MDM generally agrees that the construction of sidewalks along Osgood Street frontage is not necessary at this time since sidewalks are not currently provided along the western side of Osgood Street. However, MDM continues to recommend that the Applicant consider pedestrian connections between the site and the immediately adjacent parcels. Mr.Joseph D.Peznola, P.E. January 4, 2013 Page: 3 TRUCK CIRCULATION MDM has reviewed the revised Truck Circulation Plan and notes that the Applicant has only reviewed the feasibility of trucks entering from the south. MDM recommends that the Applicant review trucks travel paths entering from the north to ensure that no encroachment into opposing travel lanes is required in order to access the site. MDM also recommends that signs located in grassed or landscaped areas be located so that they are not struck by the delivery vehicle. MDM also notes that the WB-50 delivery vehicle is expected to be obstructed by vehicles queued in the drive-thru lane and conversely, the WB-50 delivery vehicle is expected to block access to the drive-thru lane and exit driveway during deliveries. We also note that the "Soffit Sentry height Limitation Bar" is expected to be struck by the delivery truck. MDM recommends that the Applicant review these issues and provide feasible solutions to limit the impact to site circulation during delivery times. Given the narrow width of the drive-thru lane and by-pass lane, it appears from the Fire Truck Plan (see Sheet 11) that fire apparatus may be obstructed by vehicles queued in the drive-thru lanes. The Applicant should provide correspondence from the North Andover Fire Department relative to accepting this condition. SIGHT DISTANCE The tree located just south of the exit driveway has been removed and should be referenced as such on the site plan. While the intersection sight lines exceed minimum sight distance criteria established by AASHTO, MDM recommends that the roadside vegetation in the area of utility pole #3007 (opposite the Shell service station) should be removed in order to further enhance sight distance to and from the exit driveway. MDM recommends that any proposed planting or physical landscape features should be located outside the driveway sight lines to ensure unobstructed driver visibility. TRIP DISTRIBUTION As stated above, we believe that the proposed Dunkin Donuts will serve the majority of customers currently patronizing the store at 982 Osgood Street. While we recommend that the Applicant conduct turning movement counts at the existing store to determine the expected trip distribution (percentage of left- and right-turns to and from the site), the revised site plan incorporates a separate left- and right-turn lane to accommodate exiting movements regardless of the estimated trip distribution. As such, no further review of trip distribution is required at this time. D Mr.Joseph D.Peznola,P.E. January 4,2013 Page:4 CAPACITY ANALYSIS MDM has reviewed the updated capacity analysis and is in general agreement with the findings; specifically, that left-turn movements exiting the site will experience long delays during peak hours with minor impact to operations along Osgood Street. MDM notes that although vehicle delays may be extensive (exceeding 50 seconds during peak hours), vehicle queues at the exit driveway will generally be accommodated without impacting the drive- through lane. However, the analysis does indicate that queues forming at the exit driveway may occasionally extend back to the drive-thru window resulting in a potentially longer than expected drive-thru queue. As stated above, the Applicant should identify measures to be taken should the drive-thru queue lengths exceed the storage area and impact the on-site parking supply. ON-SITE PARKING MDM had previously recommended that the Applicant conduct a parking study at a nearby similar Dunkin' Donuts since the Applicant does not meet the zoning requirements for the number of required parking spaces. MDM has reviewed the latest parking evaluation provided which is based on observations made a Dunkin' Donuts in Methuen, MA. The parking study indicates that the Dunkin' Donuts experienced a peak parking demand of 17 parked vehicles during the 11 AM — 2 PM period on a Saturday. MDM notes that the peak parking demand observed on Saturday occurred during the first time interval observed and parking demand may have been higher prior to the start of the parking observations. MDM also notes that the peak demand of 17 vehicles is close to the proposed parking supply of 19 parking spaces. As such,we note that the parking supply may not be sufficient for the proposed use. MITIGATION MEASURES The Applicant indicates that site access has been designed as to minimize off-site vehicular conflicts. MDM has reviewed the revised access design and proposed roadside vegetation clearing and is in general agreement with the proposed design. Additionally, based on the Applicant's correspondence with the Town and MassDOT, traffic signal improvements at the Route 125/Sutton Street and Route 125/Great Pond Road intersections are expected to begin construction this winter. These improvements are not anticipated to add any additional capacity to the roadway system but may improve overall traffic flow within the study area. Mr.Joseph D.Peznola,P.E. January 4,2013 Page:5 SUMMARY It is MDM's opinion that the Response to Comments memorandum adequately addresses many of the comments and recommendations made in our initial review letter. However, there are some outstanding issues that require further discussion. In particular, MDM still has some reservations regarding the feasibility of truck maneuverability in and around the site and the impact that the drive-thru queue will have on the limited supply of parking spaces. We are available to discuss these comments in greater detail at your request. We appreciate the opportunity to provide Transportation Plannutg & Engineering Services to Hancock Associates and the Town of North Andover.

COLLISION HISTORY/SITE ACCESS DRIVEWAY As recommended in our prior comment letter, the Applicant proposes to re-grade the area to the east of the proposed entrance driveway which will result in improved sight distance for vehicles exiting from 1060 Osgood Street. MDM has no further comments relative to this issue. SITE ACCESS/PEDESTRIAN ACCESS As indicated in our prior comment letter, we anticipate a significant amount of foot traffic to occur between the proposed Dunkin Donuts and 1060 Osgood Street and therefore recommend that either a pedestrian walkway be constructed between the parcels or a sidewalk be constructed along Osgood Street to accommodate pedestrian demand. In response to this recommendation, the Applicant proposes to construct a walkway to the easterly property line in an effort to provide a pedestrian connection to/from 1060 Osgood Street. The Applicant states that there is an understanding with the North Andover Planning Board that it will be the responsibility of the adjacent owner to build the remaining sidewalk to the parking lot. While this appears to be a reasonable proposal, MDM notes that the adjacent property owner may not be able to build the remaining sidewalk to ADA requirements due to the 3 to 4 foot grade difference between the end of the proposed walkway and the existing parking lot at 1060 Osgood Street. MDM recommends that the walkway be re-designed such 28 Lord Road,Suite 280 •Marlborough,Massachusetts 01752 Phone(508)303-0370 •Fax(508)303-0371 •www.mdmtrans.com Mr. Joseph D.Peznola,P.E. 'January 30, 2013 Page: 2 that it can be connected to the adjacent lot in conformance with ADA requirements. If said location cant satisfy ADA requirements than an alternative connection is recommended (e.g., a sidewalk located along Osgood Street and the site driveway). DRIVE-THROUGH LANE QUEUING MDM's initial comments relative to drive-through queuing stem from the fact that a significant range of vehicle queues have been observed at various Dunkin Donuts facilities throughout the area. One of the more common concerns relative to drive-through facilities is their potential to impact on-site parking and adjacent street traffic operations should queues spill out onto the roadway. Originally, the Applicant chose not to survey the adjacent Dunkin Donut's drive-through and instead,provided national and probability based queuing estimates. Given the fact that that the proposed stand-alone facility (1018 Osgood Street) is replacing an existing operable drive- through facility (982 Osgood Street) in such close proximity to the site, a question as to the potential impact on Osgood Street remained valid. When data from the adjacent Dunkin Donuts was eventually presented, it showed an 11 vehicle queue during the one weekday morning peak hour observation without seasonal adjustment factors being applied. While this observation suggests that the probability based queue estimate was slightly low (10-vehicle queue) and the nationally based queue estimate was slightly high (13-vehicle queue), it is an observation from one weekday and does not take into account seasonal fluctuations exhibited by Dunkin Donuts facilities. MDM notes that drive- though queue storage is typically designed for the 95th percentile queue length under peak season conditions and that, in our experience, January is typically a below average season for Dunkin Donuts facilities in the region. Therefore, it is the opinion that MDM that a queue length of 13 vehicles is more appropriate for said location. ON-SITE PARKING Based on the data and analysis presented by the Applicant, the parking supply and drive- through storage area will typically accommodate on-site operations exhibited by the Dunkin Donuts proposed for this area. However, there is a delicate balance that occurs between the drive-through operation and on-site parking activity during peak hours. At times when there is greater parking demand than there are spaces provided, which could occur on a daily basis, the drive-through queue can expect to increase. Due to the layout of the site, any increase in drive- through queuing will almost immediately result in a further reduction in effective parking supply due to the blocking of parking spaces. MDM notes that approximately 4 spaces are likely to be blocked at times during the weekday morning peak hour, thus reducing the effective parking supply at the site from 19 spaces to 15 spaces. Given the apparent site Mr.Joseph D. Peznola,P.E. January 30, 2013 Page:3 constraints, no additional parking space can be banked at the site, therefore, overflow parking may take place on the adjacent property. It should be noted that peak parking characteristics associated with the Dunkin Donuts at 982 Osgood Street are not likely to completely represent parking demands at the proposed site due to the significant increase in indoor and outdoor seating proposed. In addition, the Applicant's data demonstrated a need for only 12 spaces based on a review of the existing 982 Osgood Street facility, however, MDM notes that said facility only has an effective parking supply of 12 spaces. Therefore, the observation simply indicated that the lot was 100% full during the study period. As a final point of reference, the average peak parking demand associated with a stand-alone coffee/donut shop with drive through window is estimated at 24 spaces based on ITE parking demand data'. This estimate is highly consistent with the Town's zoning requirement of 27 spaces and should be provided at a minimum. SUMMARY In summary, we believe that the variability of drive-through queuing in combination with the layout and limited supply of parking spaces does not provide the site with the reserves needed to accommodate fluctuations in site traffic activity. During peak times, it may be necessary for patrons to circulate back out onto Osgood Street to re-enter the site, back-up within the site to get in queue for the drive-through lane and others may find it attractive to park at 1060 Osgood Street. For these reasons, we recommend that the Applicant provide 24 parking spaces at the site which is highly consistent with the Town's zoning requirement. Lastly, we believe that the walkway to 1060 Osgood Street should be re-designed so that the adjacent property owner has a reasonable chance to extend the walkway to his/her property given the significant grade separation.

Eggleston's review: ® Applicant provided data from additional test pits. Also raised the elevation of infiltration system#2, so that it has the 2' separation from ESHGWT ® Storage volume has been increased to treat the 1/2"water quality volume within the infiltration systems,however it does not meet the standards. If the systems do not overflow into the wetlands in the back of the property,they could overflow into the drainage in Osgood St. and it is not clear that there is not an obstruction to the flow. The increased flow could become a problem. Civil Review—Summary of Hancock Review: ® Parking: Applicant requests a reduction in parking from required 27 spaces to 19. Requesting relief under section 8.1.8.g, which allow for reduction in parking under certain circumstances,where it can be demonstrated that a use needs lesser number of spaces, i.e., housing for people with disabilities, low vehicle ownership. Section f addresses Land Bank Parking. Reviewer recommends that section f. should apply. ® The applicant asserts that the proposed 19 spaces will be sufficient for peak usage based on actual traffic counts performed at the existing DD location and at a stand-alone location in Methuen. ® Applicant submitted data for two locations (existing Osgood St. location, stand- alone Methuen DD) including peak time parking for both locations: ® Osgood St. —Lot contains 19 spaces. Peak time usage observed was 12 ® Methuen stand-alone DD: 13 and 16 peak time usage. Lot contains 31 spaces. ® Applicant also submitted information on other DD establishments.No traffic counts,just total spaces: Salem NH: total spaces 13; Methuen(Route 97) 17 total spaces and Windham NH,total spaces 17. ® The peer reviewer does not agree that 19 spaces is sufficient, since the observed peak at Methuen is 16. ® Methuen(Route 97) contains 48 spaces. There are multiple uses at this site. ® Dracut and Middleton both have more than 30 spaces. ® New store will have more seats, larger store. ® Other installations have over 30 spaces. ® Existing Osgood St. has spaces in the back that may not be conveniently accessed. I think the applicant has provided enough detailed information to justify the 19 spaces. There are similar stand-alone sites with fewer total spaces and similar sites with more spaces. The Board did discuss at the last meeting the"human behavior" factor—will customers pass by a site that has a long queue and no visible empty parking spaces? Also,the applicant is being asked to reduce impervious cover due to Watershed restrictions. ® Fiscal Impact and Community Impact—the applicant is requesting a waiver and should provide a basis for that request. 1 .1018 Osgood St. Review January 30, 2013 Traffic Review—Summary ® Queuing at exit driveway from drive-thru: Reviewer maintains that a 13 car queue is possible and would impact more parking spaces than the employee and accessible spaces.

The plans have been revised to reflect the comments from Hancock Associates in correspondence dated January 15, 2013 as well as comments from MDM Transportation Consultants, Inc. (MDM) in correspondence dated January 15,2013 and January 24,2013 and received in this office on Januaryl6,2013 and January 25, 2013 from your office via email. Based on the MMM comments dated January 15, 2013,we offer the following: COLLISION HISTORY Due to the close proximity of the entrance driveway to 1060 Osgood Street, MDM recommends that the Applicant modify the grading to the east of the proposed entrance driveway(within the State Highway layout) in order to improve sight distance for vehicles exiting from 1060 Osgood Street. MHF Comment. The grading in the area directly to the west of the site driveway for 1060 Osgood Street has been revised according to the sketch provided by MDM. SITE ACCESS/PEDESTRAIN ACCESS MHF Response: A proposed 4 foot wide bituminous sidewalk has been provided to the adjacent property to the east but up to the property line. It will be the responsibility of the adjacent property owner to build the remaining sidewalk to the parking lot. This was discussed and agreed to with the North Andover Planning Board. ENGINEERS PLANNERS SURVEYORS MHF Design Consultants, Inc. TRUCK CIRCULATION The Town Planner has requested comments from the Fire Department relative to this issue. Based on the comments from MDM's correspondence dated January 24, 2013 we offer the following: With respect to the drive thru queuing, MDM has chosen to apply the queuing analysis that has resulted in the most amounts of vehicles in a queue(13 vehicles). As stated in the Response to Comment letter prepared by Greeman Peterson, Inc. (GPI) dated January 15, 2013 the Traffic Impact and Access Study (TIAS) prepared for the project provided data for a 13 vehicle queue. These data were documented by the Institute of Transportation Engineers (ITE) and were based on observations conducted at 12 Starbucks coffee shops as well as 6 coffee shop locations. Starbucks has a different and more extensive product line than found at a Dunkin Donuts, therefore the process times are typically much longer resulting in longer drive thru queues. In MDM's Drive Thru Vehicle Queuing comment within their November 9, 2012 letter, NIDM states that"Based on past experience,N1DM finds that drive-thru operations for Dunkin Donuts locations are unique relative to other fast food restaurants with drive thru windows". Based on this comment we specifically provided an alternate queuing analysis which was conducted based on service times for Dunkin Donuts facilities and indicated a 95th percentile queue of 10 vehicles. As stated in NMMs January 4, 2013 letter "....we recommend that the applicant collect trip generation and vehicle queuing data from the existing facility (982 Osgood Street) as we believe that this is the best data available for estimating peak hour operations at the proposed store. Specifically trip generation and peak hour drive fl-iru queue lengths are critical components to their site operations with potential impact on the accessibility to the limited supply of parking spaces proposed." Based on this comment, we counted the existing facility located at 982 Osgood Street to collect trip-generation data and drive thru window vehicle queues. The existing observations revealed that the Dunkin Donuts restaurant generated less vehicle trips than what were previously evaluated. In addition, the existing drive thru lane observations showed a maximum of 11 vehicles occurring during the weekday AM peak hour, which would impact the parking minimally for a very short period of time. The reviewer has chosen to disregard the data that was specifically requested to be collected at the nearby facility that shows fewer vehicles in the drive thru queue, and now wants to impose the maximum queuing on the site that was originally presented in the TIAS. It is uncertain as to why the reviewer rejected the additional data that they requested at the existing Dunkin Donuts restaurant (982 Osgood Street) that resulted in additional time and expense if this information was believed to provide the most applicable comparison to the operations at the proposed restaurant. IVIHF Design Consultants, Inc. We believe that the expected queuing for the drive thru will be accommodated on-site and will cause minimal,if any disruption to the on-site parking. ON-SITE PARKING With respect to the proposed parking spaces, MMM requested that we count the parking operations at a free-standing Dunkin' Donuts facility. Based on this request, we observed that the maximum occupied spaces to be 17 spaces at 450 Broadway in Methuen, Massachusetts. After receiving this information, the reviewer has commented (January 4, 2013 letter) that the proposed 19 parking spaces may be inadequate. Based on this comment, we counted the existing facility located at 982 Osgood Street and observed the maximum occupied spaces to be 12 spaces. The Parking Demand Studies conducted at the two existing facilities provided occupied spaces less than the 19 spaces being provided at the proposed site. Based on the information provided,the data suggest that the peak-parking demand can be accommodated on the site. Parking spaces that were provided in the last response letter for other sites were merely provided as information showing that other similar sites have spaces equal to or less than those provided on the proposed site. No actual parking counts were done for these other sites. /J Sincerely yours, ;,i 1 MHT DES C( TSITL;TNTS,INC. �i ss. E. Principal Cc: Mr.Dan Mills,MDM Transportation Consultants,Inc.

The plans have been revised to address the comments in the Eggleston Environmental review letter dated January 7,2013. Based on those comments, as shown below,we offer the following responses in bold: 1. At our meeting on 11/19, we discussed the need for distributing recharge across the project site, and particularly within the Watershed Protection District. I indicated to MHF that even if there was less than two feet of separation to the seasonal high groundwater elevation, an infiltration system within the WPD should still be able to provide effective recharge and filtering of flow under most periods of lower groundwater. With the additional test pit. data included in this submission, however, a clearer picture of the groundwater conditions on the site emerges, and I question whether any below-grade system can be used to effectively infiltrate stormwater within the WPD. Seven of the eight test pits conducted on the site (four in August 2012 and another four in November 2012) indicate that the high groundwater elevation is approximately three to four feet below existing grade across the site. Evidence of groundwater was not seen in the eighth test pit, however based on the other test pits the ESHGW was estimated to also be four feet below grade. Thus, the ESHGW elevation across most of the project site ranges from elevation 144 to 140. Infiltration System #1 (near the wetland) is located in a portion of the site where the proposed ground elevation will be raised. The bottom of the stone in the system would only be 1.2 feet above the ESHGW, but the system should be able to function adequately most of the time. Proposed Infiltration System 42, however, is located in a cut portion of the site, where the proposed surface grades will be lowered by approximately three feet. The entire below-grade infiltration system, with a bottom invert of 136.67, would therefore be several feet lower than the ESHGW elevation in that area, and likely to be in groundwater most of the year. ENGINEERS PLANNERS . SURVEYORS Ms.Judy Tymon January 28,2013 Page 2 of 3 MHF Design Consultants,Inc. Response: Additional test pits have been performed on 1/28/13 and added to the Plan Set and Stormwater Report and the results provide consistent data with the previously submitted logs. Please note that infiltration system #2 has been raised two additional feet compared to the previous design. In addition,the results of Test Pit#113-4 indicate a depth to eshwt of 6',thereby providing the required 2' of separation to the eshwt to proposed infiltration system N. 2. Even without the groundwater issue, the proposed plan only attenuates the rate of runoff flow leaving the site, not the volume. The volume of flow discharged to Osgood Street under post-development conditions would more than twice the existing runoff volume under every design storm condition, and could exacerbate j any downstream flooding. Response: We have increased the volume capacity within both infiltration systems to the maximum extent based on the existing site conditions. In order to mitigate the Post Development volumes the onsite infiltration systems would need to be increased in upwards of 5-10x the size of the currently proposed system and in our opinion is unreasonable and inconsistent with previous developments approved in Town. 3. The proposed design also does not provide sufficient dead storage volume in the infiltration systems to capture and treat even a '/2-inch water quality volume. The TSS calculations submitted include storage volume in the Oil/Grit Chambers to reduce the water quality volume in the infiltration systems. This is an invalid assumption for two reasons. First, the oil/grit chambers are solid structures and are designed to operate full and to remain full between storms — they have no storage capacity. Second, the treatment provided in the infiltration system is only in the flow that is actually captured and infiltrated; the overflow from the system is not treated. Therefore in order to get the 80% TSS removal credit the entire water quality volume must be captured and infiltrated. Response: Storage volume within both infiltration systems has been increased to treat the 1/2-inch water quality volume. 4. It is not clear what the basis is for the saturated thicknesses of 129 and 133 ft used in the mounding calculations. As indicated in my previous comments, saturated thickness should be the difference between ESHGW and the bottom of the aquifer,probably something in the range of 10 to 15 feet. The model may call for an elevation,but it also needs the relative elevations as the saturated thickness of the aquifer is part of what determines how quickly the additional groundwater flow is dispersed. The elevations used in the analysis are not even consistent with the ESHGW on the site. Response: The saturated thickness was taken by subtracting the 10 to 15 feet from the ground surface elevation at each test pit location in the vicinity of each infiltration system. This has been revised by subtracting the 10 to 15 feet from the eshwt as suggested. Ms.Judy Tymon �� •... January 28,2013 — — Page 3 of 3 MHF Design Consultants,Inc. 5. The detail for the Snout Oil/Water separator on Sheet 8 should be clarified or relabeled to indicate that it is the outlet hood for the catchbasins, so as not to confuse it with the detail for the larger oil/water separator chambers. I would actually suggest that the larger chambers be called out as oil-grit chambers. The detail for the Stormceptor units should also be removed from the plan. Response: The detail for the Snout Oil/Water separator has been relabeled as suggested and the Stormceptor unit details have been removed from the plan set. 6. An application for a Watershed Special Permit, including a written certification by a professional engineer stating that the project will not cause any significant degradation in the quality or quantity of water in or entering Lake Cochichewick is still needed. Response: Written certification has been provided as suggested. Based on the revised plans and documents,we feel that we have addressed the comments in both the review letter and the staff meeting.

As you know,MBF Design Consultants met with yourself,Jennifer Hughes and Ms. Eggleston on March 7, 2013 to review the additional comments from Eggleston Environmental relative to the above referenced project. The attached plans and revised Drainage Report incorporate revisions based on the design options discussed at that meeting. Specifically we have revised the plans as follows: 1. The roof drainage has been redirected into infiltration system#2 and the pavement area in the lower parking lot has been redirected to other systems; a portion going to infiltration system#1 and another portion going to the sand filer located at the front portion of the site. This has allowed us to raise the bottom of infiltration system#2 to elevation 144.00 which provides for a greater separation from the estimated seasonal high water table. Two test pits in the area of infiltration system#2 indicated a variation in the depth of the seasonal high water table from none observed at 120" (1112-4) at the west end of the site to 48" faint(1112-4) on the east end of the site. It was also discussed that this seasonal high water table elevation at this location is potentially created as a result of runoff from the roof not being controlled and creating this condition. It would be reasonable to assume that the average seasonal high water table would be approximately at a depth of 6 feet or at elevation 142+/-. This is substantiated by other test pits in the immediate vicinity and shown on the revised plans(113-2 and 113-3). Using this estimated seasonal high water table elevation would provide a 2 foot separation from the bottom of the proposed infiltration system#2. 2. A portion of the site's lower parking area has been intercepted thru the use of a trench drain that will capture the pavement runoff and direct it to infiltration system#1. This runoff had gone to infiltration system#2 in the previous design. Additionally, some runoff from the lower area will also be captured and be directed into the proposed sand filter located at the front of the site. 3. Both infiltration systems have been enlarged to provide as much storage as possible to reduce the volume of flow from the site.

Included in the report are exhibits which provide for documentation regarding the issue of additional volume from the site as a result of the development See Appendix D. Based on these exhibits and our documentation and calculations,the additional volume from the site that will be directed to the wetland thru the Osgood Street drainage system is an additional 1,523 cf. Based on the ponded area of the wetland that is at the outlet of this drainage system being 80,000 sf,the additional volume represents an increase of this ponded wetland area of only 0.019 feet or 0.22 inches . Additionally, we were conservative in the calculation of the area at the outlet and restricted it to just the observed ponded area, Based on the aerial photo,the wetland area associated with the outlet of this drainage system is much larger, approximately 3 times the size that we calculated for the ponded area of the existing outlet,which would suggest an even smaller increase. Based on the revised plans and documents,we feel that we have addressed the comments in both the previous review letters and the March 7,2013 meeting.

The plans have been revised to reflect the comments from Hancock Associates in correspondence dated December 30, 2012 and received in this office on January 7,2012 from your office via email. Based on those comments we offer the following: 1. The Applicant has requested a Special Permit under Section 8.1 for reduction in parking. The Applicant's reference to Section 8.1.81 appears incorrect and should be Section 8.1.8.g"Reduction in Parking". The Board should review the applicability of this section, as the use does not seem to align with the uses described in this section. The section speaks to uses such as those for persons with disabilities, low rate of vehicle ownership or the availability of transportation demand management alternatives. The Board may wish to explore the application of Section 8.1.8.f in this case; "Land Banked Parking" as being more appropriate to the use given the Applicant's arguments. Additionally,the Applicant has miscalculated the number of spaces required. In accordance with Section 8.1.4 (note 4 of Table of Off-Street Parking), "where uses are open-air type not enclosed in a structure, each foot of lot devoted to such use shall be considered to be equivalent to one fifth of one square foot". The 25' x 30'outdoor seating area requires an additional two spaces. ENGINEERS 0 PLANNERS SURVEYORS MHF Response:An additional Special Permit is being requested. MHF Design Consultants, Inc. Hancock Comment: The parking as been further reduced to 19 spaces. Again, Hancock believes that the Applicant should utilize Section 8.1.81. In this manner, should parking demand exceed the supply,the Town could require the Applicant build the land banked parking.The additional,parking demand study performed by the Applicant on a site in Methuen found the parking demand to be 17 spaces,fairly close to the 19 provided. MHF RESPONSE: Land banking the parking does not assist us with the reduction of pavement for purposes of complying with the Watershed Protection District requirements since we would have to account for those spaces in the drainage design of the site and defeats the purpose of impervious reduction. Additional documentation is being supplied to MDM regarding this issue with respect to additional sites and a parking count of the existing site located just to the south of this parcel. 2. The Applicant has requested waivers from Section 8.3.5.e requiring the submission of a Fiscal Impact Study and a Community Impact Analysis. The Applicant argues that the project is minor in nature. The Bylaw has provisions defining minor projects (less than 2,000 s.f.). The Board should instruct the Applicant to provide the required study and analysis. MHFResponse: We stand by our request for waivers from these items. Hancock Comment: Hancock defers to the Board regarding this matter. MHF Response: Comment acknowledged 3. The Applicant has requested that the Board make a Determination of Applicability and/or grant a waiver in accordance with eth provisions of Section 4.136 Watershed Protection. Section 4.136.2.c states"In the event the SPGA determines, on the basis of credible evidence before it, that there exists a significant doubt or dispute concerning the proper location of the boundaries of the Watershed Protection District on any individual lot or lots, the SPGA shall, at the request of the owner of such lot or lots, engage a Registered Professional Engineer to advise it in determining such boundaries". We see this process as separate and distinct from the Applications before the Board and that the report and decision of the Board precedes any action by the Board on the application at hand. We understand the Board has engaged Lisa Eggleston as the Registered Engineer advising the Board. Hancock has reviewed the Existing Conditions Plan and letter from Epsilon and notes that assertion with regard to drainage patterns are not clearly depicted on the Plan. Drain lines shown on the plan are incomplete. A review of the Existing Conditions Plan prepared by MHF Consultants for the 1003 Osgood Street Project do not support the detail outlined in the Epsilon letter. The Existing Conditions plan should be updated to reflect this detail. MMONEENOMEW =MEW WN so= M=V MHF Response:A separate Watershed Special permit application hdillephs)Wgonsultants, Inc. for a portion of the property based on our meeting with the Town's Environmental Consultant. Hancock Comment: Hancock defers to Ms.Eggleston and the Board regarding this matter. MHF Response: Comment acknowledged 4. No loading area(12'x25'xl4') is proposed as required by Section 8.1.5.e. MHF Response:An additional Special Permit has been requested, Hancock Comment: Hancock believes there is sufficient space to the south of the dumpster where the edge of pavement has a radius of 45 feet(assumedly for truck turning)that could be slightly expanded and squared off to accommodate a single box truck. We understand box trucks are used for daily delivery of donuts from regional bakeries.Any other location for trucks to park would impede the one-way circulation regardless of it being off-peak hours. MHF Response: The daily delivery of donuts is made early in the morning between the hours of and 6 am, well before any appreciable customer traffic for the drive thru is made and is done from the by-pass lane....the time of the delivery is literally 5 tolOminutes. Virtually all stores operate this way in terms of the delivery ofproduct and therefore are not an impediment to the operation of the site for the drive-thru. Again the purpose as described above is to reduce the amount of impervious surfaces on this site for drainage design purposes. We will request the Special Permit from the Board regarding this request. Section 8.3.5 Additional Information Required: 1. Zoning Section 8.35.d requires that an Architect registered in the Commonwealth of Massachusetts stamped all building elevations. An Architect Registered in New York stamps the elevations submitted. MHF Response:Building Plans will be submitted to the North Andover Building Department and will be stamped by a Registered Architect in Massachusetts. Hancock Comment: The By-law requirement pertains to submission to the Planning Board. This is an open item. General Engineering Review Comments 1. Queuing should be adjusted to provide 20' per vehicle. Queuing for only four to five vehicles are provided from the order board back prior to impacting parking spaces. The Applicant should consider designating several impacted spaces as employee parking. MHFResponse: The queuing has been verified by the traffic consultant and we will designate the spaces at the end of the drive thru queue as employee spaces. Hancock Comment: Hancock defers to NMM Transportation for review of the additional information submitted by the Applicant regarding the queuing. MHF Response: GPI, Inc is providing additional information relative to the queuing at the existing site. MERMW mm now MHF Design Consultants, Inc. 2. Light levels on the sidewalk at the proposed appear too low. It is recommended at least 1.0 foot-candle is provided within pedestrian areas. MHF Response: The lighting plan is sufficient for the use and does not take into account the lighting coming from inside the store which provides additional lighting in the sidewalk areas. Hancock Comment: Hancock believes the area of low light is far enough from the building such that internal lighting may not be sufficient to address the issue. A sidewalk bollard light may be necessary to address the issue. MHF Response: We will resubmit a revised lighting plan to address this issue. Review Criteria/Design Guidelines 1. The Applicant states that the project will be connected to municipal sewer and water as evidence that the municipal system has the ability to serve the project. More detail with regard to available system capacity and actual project demands should be provided. MHF Response:A typical Dunkin Donuts of this size will generate 380 Bpd. The flow rate can be accommodated by the existing 8"sewer line in Osgood Street. Hancock Comment: The Applicant should verify that there are no existing issues with the sewer in the area. MHF Response: Comment acknowledged This letter serves to confirm that a majority of the issues have been satisfied and the only outstanding issues are those described above that will need to be discussed by the Board.

The plans have been revised to reflect the comments from Hancock Associates in correspondence dated December 30, 2012 as well as comments from MDM Transportation Consultants, Inc. (MDM) in correspondence dated January 4, 2012 and received in this office on January 7,2012 from your office via email. Based on the MDM comments we offer the following: TRIP GENERATION We believe that the proposed Dunkin Donuts will serve the majority of customers currently patronizing the store at 982 Osgood Street. As such, we recommended that the Applicant collect trip generation and vehicle queuing data from the existing facility as we believe that this is this best data available for estimating peak hour operations at the proposed store. Specifically, trip generation and peak hour drive-thru queue lengths are critical components to the site operations with potential impact on the accessibility to the limit supply of parking spaces proposed. AIHF Comment. GPI will be providing that data via counts performed the week of January Th and will be submitted under separate cover to this letter. COLLISION HISTORY As recommended by MDM, the Applicant has reviewed additional crash data and has determined that, while there are a relatively high number of accidents occurring in the study area, the collisions do not indicate a particular pattern correctable by engineering measures. Additionally,the Applicant has revised the site driveway layout,has removed a large tree along ENGINEERS 0 PLANNERS 0 SURVEYORS MHF Design Consultants, Inc. the site frontage and proposes to clear roadside vegetation to enhance safety for motorists exiting the site. Due to the close proximity of the entrance driveway to 1060 Osgood Street, MDM recommends that the Applicant modify the grading to the east of the proposed entrance driveway(within the State Highway layout) in order to improve sight distance for vehicles exiting from 1060 Osgood Street. AMF Comment: The on-site and ROW grading to the east of the driveway for 1060 Osgood Street has been revised to provide for improved site distance over what exists on the property currently. DRIVE-THROUGH LANE VEHICLE QUEUING The Applicant has conducted an alternative drive-thru queue analysis which results in a maximum queue of 10 vehicles in the drive-d-tru lane during the weekday morning peak hour. This estimate is generally based on national trip generation statistics for coffee/donut shops and is not necessarily representative of the drive-thru queues generated by Dunkin Donuts in New England. In addition, the Applicant's prior traffic study indicated a peak vehicle queue of 13 vehicles, The Applicant should explain this discrepancy and identify measures that will be taken should the drive-thru queue lengths exceed the storage area and impact the on-site parking supply. MHF Comment. We disagree regarding the comment about the queuing analysis not being representative of Dunkin Donuts in New England. This analysis was done specifically for the Dunkin Donuts drive thru based on a service time of 30 seconds which is their standard service time for all stores and hag been used specifically for Dunkin Donuts throughout New England. As in the Trip Generation response above, GPI will be supplying queuing information for this site based on the existing site for AM and Saturday peak periods and will be submitted under separate cover to this letter. The impact to the on-site parking supply if the queuing exceeds ten vehicles will potentially affect 2-3 spaces, of which 2 are designated as employee parking and one is designated as an accessible space. SITE ACCESS The Applicant has modified the site layout and access design to include one-way counterclockwise circulation in and around the site with entrance-only movements at the northern site driveway and egress-only movements at the southern site driveway. MDM generally concurs with the revised site layout and access design and generally concurs that reducing the number of access/egress locations to one entrance-only driveway and one egress- only driveway will minimize vehicular conflicts and provide for more efficient on-site parking flow. MDM also generally concurs with the construction of exclusive turn lanes at the egress driveway which will better accommodate on-site vehicle queues. MHF Design Consultants, Inc. The Applicant states that the access has been designed to accommodate sidewalk construction along the site frontage should the Town or MassDOT construct sidewalk along the western side of Osgood Street in the future. MDM generally agrees that the construction of sidewalks along Osgood Street frontage is not necessary at this time since sidewalks are not currently provided along the western side of Osgood Street. However, MDM continues to recommend that the Applicant consider pedestrian connections between the site and the immediately adjacent parcels. A1HF Response. Providing pedestrian access to either site would require cooperation and permission from the adjacent property owners for construction of any access on their property for a connection. The owner is not in a position to negotiate those connections. Additionally, the connection to the property to the south/west would be difficult at best given the grade change. TRUCK CIRCULATION MDM has reviewed the revised Truck Circulation Plan and notes that the Applicant has only reviewed the feasibility of trucks entering from the south. MDM recommends that the Applicant review trucks travel paths entering from the north to ensure that no encroachment into opposing travel lanes is required in order to access the site. MDM also recommends that signs located in grassed or landscaped areas be located so that they are not struck by the delivery vehicle. A4HF Response: A revised truck turning plan has been included in the revised plans to show delivery trucks entering from the north. MDM also notes that the WB-50 delivery vehicle is expected to be obstructed by vehicles queued in the drive-thru lane and conversely, the WB-50 delivery vehicle is expected to block access to the drive-thru lane and exit driveway during deliveries. We also note that the "Soffit Sentry height Limitation Bar" is expected to be struck by the delivery truck. MDM recommends that the Applicant review these issues and provide feasible solutions to limit the impact to site circulation during delivery times. AMF Response:as discussed in our meeting,Dunkin Donuts has only two delivery trucks a week of the WB-50 size and these deliveries are done at off peak hours. Additionally, they off load these vehicles in the by-pass lane, thereby not impeding the use of the drive thru lane. This is how a majority of these sites operate for loading and unloading. The "'Soffit Sentry Height limitation Bar"is optional and has been removed from the site plan. Given the narrow width of the drive-thru lane and by-pass lane, it appears from the Fire Truck Plan (see Sheet 11) that fire apparatus may be obstructed by vehicles queued in the drive-thru lanes. The Applicant should provide correspondence from the North Andover Fire Department relative to accepting this condition. MHF Response: We will coordinate with the Fire Department. e MHF Design Consultants, Inc. SIGHT DISTANCE The tree located just south of the exit driveway has been removed and should be referenced as such on the site plan. While the intersection sight lines exceed minimum sight distance criteria established by AASHTO, MDM recommends that the roadside vegetation in the area of utility pole #3007 (opposite the Shell service station) should be removed in order to further enhance sight distance to and from the exit driveway. MDM recommends that any proposed planting or physical landscape features should be located outside the driveway sight lines to ensure unobstructed driver visibility. MHF Response: The site plan has been updated to show this tree to be removed south of the exit driveway. A note has been added regarding clearing of vegetation in the vicinity of the utility pole # 3007 and no landscaping is located within the driveway sight lines as depicted on the revised Landscape Plan. CAPACITY ANALYSIS MDM has reviewed the updated capacity analysis and is in general agreement with the findings; specifically, that left-turn movements exiting the site will experience long delays during peak hours with minor impact to operations along Osgood Street. MDM notes that although vehicle delays may be extensive (exceeding 50 seconds during peak hours), vehicle queues at the exit driveway will generally be accommodated without impacting the drive- through lane. However, the analysis does indicate that queues forming at the exit driveway may occasionally extend back to the drive-thru window resulting in a potentially longer than expected drive-thru queue. As stated above, the Applicant should identify measures to be taken should the drive-thru queue lengths exceed the storage area and impact the on-site parking supply- AH—IF Response: As stated above in the Drive-Through Lane Vehicle Queuing response, the impact to the on-site parking supply will potentially affect 2-3 spaces, two of which are designated as employee parking and 1 is designated as an accessible parking space. ON-SITE PARKING MDM had previously recommended that the Applicant conduct a parking study at a nearby similar Dunkin' Donuts since the Applicant does not meet the zoning requirements for the number of required parking spaces. MDM has reviewed the latest parking evaluation provided which is based on observations made a Dunkin' Donuts in Methuen, MA. The parking study indicates that the Dunkin' Donuts experienced a peak parking demand of 17 parked vehicles during the 11 AM — 2 PM period on a Saturday. MDM notes that the peak parking demand observed on Saturday occurred during the first time interval observed and parking demand may have been higher prior to the start of the parking observations. MDM also notes that the F iii Design Consultants, Inc. peak demand of 17 vehicles is close to the proposed parking supply of 19 parking spaces. As such,we note that the parking supply may not be sufficient for the proposed use. MHF Response: We believe that 17 spaces are more than adequate for the patrons utilizing this particular site. GPI will be providing a similar count of parking space utilization at the existing site in addition to the one performed at the Dunkin Donut site in Methuen. Additionally,we have looked at other Dunkin Donut sites in the area and will provide parking space counts for those facilities which in some cases are less than the spaces being proposed for this facility. This information from GPI will be provided under separate cover. We believe that this addresses all the outstanding issues that have been outlined in MDM's correspondence and look forward to a final response from MDM regarding the traffic issues for this project.

Hancock Associates EgglestonEnvironmentl January 7, 2013 North Andover Planning Board 1600 Osgood Street North Andover, MA 01845 Attn: Judy Tymon, Town Planner RE: 1018 Osgood Street Stormwater Management Review Dear Ms. Tymon and Board Members: I am writing this letter in follow-up to my November 14,2012 review letter on the above- referenced project. Since that time I have received and reviewed the December 7, 2012 revised plans and Stormwater Management Report submitted by MHF Design Consultants. I also participated in a meeting with town staff and the applicants on November 19, 2012 to discuss my comments and the issues on the site. The design revisions reflect a decrease in overall impervious area on the site and provide stormwater recharge through two proposed infiltration systems, one in the area draining to the onsite wetland and one in the front portion of the site, in the Watershed Protection District. The proposed Stormeeptor unit has been eliminated, as water quality treatment of runoff flows is to be provided through the oil/grit chambers and infiltration systems. The revised drainage analysis reflects these design revisions and uses the more conservative Rawls rate for modeling of exfiltration. I note that the revised Stormwater Report also includes data from four additional test pits conducted on the site in November 2012. My comments on the revised submittal are outlined below: 1. At our meeting on 11/19, we discussed the need for distributing recharge across the project site, and particularly within the Watershed Protection District. I indicated to MHF that even if they could not provide a two-foot separation to the high groundwater elevation, an infiltration system within the WPD should still be able to provide effective recharge and filtering of flow under most groundwater conditions. With the additional test pit data, however, a clearer picture of the groundwater conditions on the site emerges, and I question whether any subsurface infiltration system can be used to effectively recharge or treat flow within the WTD. Seven of the eight test pits conducted on the site (four in August 2012 and another four in November 2012) indicate that the high groundwater elevation is approximately three to four feet below existing grade across the site. Evidence of groundwater was not seen in the eighth test pit,however based on the other test pits the ESHGW was estimated to also be four feet below grade. Thus, the ESHGW elevation across most of the project site ranges from elevation 144 to 32 Old Framingham Rd Unit 29 Sudbury MA 01776 tel 508.259.1137 fax 866.820.7840 1018 Osgood Street, Stormivater Review 2 January 7, 2013 140. Infiltration System #1 (near the wetland) is located in a portion of the site where the proposed ground elevation will be raised. The bottom of the stone in the system would only be 1.2 feet above the ESHGW, but the system should be able to function adequately most of the time. Proposed Infiltration System #2, however, is located in a cut portion of the site, where the proposed surface grades will be lowered by approximately three feet. The entire subsurface infiltration system, with a bottom invert of 136.67, would therefore be several feet below the ESHGW elevation in that area, and likely to be in groundwater most of the year. 2. Even without the groundwater issue, the proposed plan only attenuates the rate of runoff flow leaving the site, not the volume. The volume of flow discharged to Osgood Street under post-development conditions would more than twice the existing runoff volume under every design storm condition, and could exacerbate any downstream flooding. 3. The proposed design also does not provide sufficient dead storage volume in the infiltration systems to treat even a 1/2-inch water quality volume. The TSS calculations use the storage volume in the Oil/Grit Chambers to reduce the water quality volume in the infiltration systems. This is an invalid assumption for two reasons. First, the oil/grit chambers are solid structures and are designed to operate full and to remain full between storms. Second, in order to provide the treatment necessary to get the 80% TSS removal credit in the infiltration systems the entire water quality volume must be infiltrated. 4. It is not clear what the basis is for the saturated thicknesses of 129 and 133 $used in the mounding calculations. As indicated in my previous comments, saturated thickness should be the difference between ESHGW and the bottom of the aquifer, probably something in the range of 10 to 15 feet. The model may call for an elevation, but it also needs the saturated thickness of the aquifer as this is part of what determines how quickly the additional groundwater flow is dispersed. These elevations are not even consistent with the ESHGW on the site. 5. On Sheet 8, the detail for the Snout Oil/Water separator should be clarified/relabeled to indicate that it is the outlet hood for the catchbasins, so as not to confuse it with the detail for the larger oil/water separator chambers. I would actually suggest that the larger chambers be called out as oil-grit chambers. The detail for the Stormceptor units should also be removed from the plan. 6. An application for a Watershed Special Permit, including a written certification by a professional engineer stating that the project will not cause any significant degradation in the quality or quantity of water in or entering Lake Cochichewick is still needed. Once again,I appreciate the opportunity to assist the North Andover Planning Board with the review of this project, and hope that this information is suitable for your needs.

MHFResponse: The deed is from 1950 and describes the property at that time.In 1061 there was a highway taking along Route 125, hence the difference in the plan versus the deed. This has no affect on the grandfathering issues for the project. Hancock Comment: We are satisfied with the response. 2. The Zoning for the parcel was changed at the June 12,2012 Town Meeting from Industrial 2 to Business 2. The property has B2 zoned parcels to the east and west. The airport parcel to the north remains 1-2 zone. This zone line should be reflected on the project plans. MHFResponse: The plan has been revised Hancock Comment: We are satisfied with the response. 3. It appears the project is compliant with use and basic dimensional requirements of the North Andover Zoning By-Law. Comment acknowledged. 4. The Applicant has requested a Site Plan Special Permit under Section 8.3. Comment acknowledged. 5. The Applicant has requested a Special Permit under Section 8.1 for reduction in parking. The Applicant's reference to Section 8.1.81 appears incorrect and should be Section 8.1.8.g"Reduction in Parking". The Board should review the applicability of this section, as the use does not seem to align with the uses described in this section. The section speaks to uses such as those for persons with disabilities, low rate of vehicle ownership or the availability of transportation demand management alternatives. The Board may wish to explore the application of Section 8.1.8.f in this case; "Land Banked Parking"as being more appropriate to the use given the Applicant's arguments.Additionally,the Applicant has miscalculated the number of spaces required. In accordance with Section 8.1.4 (note 4 of Table of Off-Street Parking), "where uses are open-air type not enclosed in a structure, each foot of lot devoted to such use shall be considered to be equivalent to one fifth of one square foot". The 25' x 30'outdoor seating area requires an additional two spaces. MHFResponse:An additional Special Permit is being requested. Hancock Comment: The parking as been further reduced to 19 spaces.Again, Hancock believes that the Applicant should utilize Section 8.1.8.f.In this Marlborough, MA Danvers, MA 315 Elm Street 185 Centre Street www.hancockassociates.com manner,should parking demand exceed the supply,the Town could require the Applicant build the land banked parking. The additional parking demand study performed by the Applicant on a site in Methuen found the parking demand to be 17 spaces,fairly close to the 19 provided. 6. The Applicant has requested waivers from Section 8.3.5.e requiring the submission of a Fiscal Impact Study and a Community Impact Analysis. The Applicant argues that the project is minor in nature.The Bylaw has provisions defining minor projects(less than 2,000 s.f.). The Board should instruct the Applicant to provide the required study and analysis. MHFResponse: We stand by our requestfor waivers from these items. Hancock Comment: Hancock defers to the Board regarding this matter. 7. The Applicant has requested that the Board make a Determination of Applicability and/or grant a waiver in accordance with eth provisions of Section 4.136 Watershed Protection. Section 4.136.2.c states"In the event the SPGA determines, on the basis of credible evidence before it, that there exists a significant doubt or dispute concerning the proper location of the boundaries of the Watershed Protection District on any individual lot or lots, the SPGA shall, at the request of the owner of such lot or lots, engage a Registered Professional Engineer to advise it in determining such boundaries". We see this process as separate and distinct from the Applications before the Board and that the report and decision of the Board precedes any action by the Board on the application at hand. We understand the Board has engaged Lisa Eggleston as the Registered Engineer advising the Board. Hancock has reviewed the Existing Conditions Plan and letter from Epsilon and note that assertion with regard to drainage patterns are not clearly depicted on the Plan. Drain lines shown on the plan are incomplete.A review of the Existing Conditions Plan prepared by NIHF Consultants for the 1003 Osgood Street Project do not support the detail outlined in the Epsilon letter. The Existing Conditions plan should be updated to reflect this detail. MHFResponse:A separate Watershed Special permit application has been filed for a portion of the property based on our meeting with the Town's Environmental Consultant. Hancock Comment: Hancock defers to Ms.Eggleston and the Board regarding this matter. 8. The plan does not appear to comply with the buffering requirements of Section 8.4 with regard to planting and/or fencing along the east property line and the number of tress per linear foot of parking. MHFResponse:A 6-foot high stockade fence has been shown on the Landscape and Lighting Plan. Hancock Comment: The plan now complies with Section 8.4 of the By-law. 9. The plan does not comply with the requirement of Section 8.1.4.b calling for handicapped spaces located nearest the door. MHFResponse: The plan shows handicap spaces which will provide equal access to the front door as well as the rear door of the facility which is primarily for the employees. Marlborough, MA Danvers, MA 315 Elm Street 185 Centre Street www.hancockassociates.com Hancock Comment: We are satisfied with the response. 10. The plan does not meet he requirements of Section 8.1.5.a calling for a 25' parking aisle;24' is proposed. MHFResponse: The plan has been revised. Hancock Comment: The plan now complies with Section 8.1.5 of the By-law. 11.No loading area(12'x25'xl4') is proposed as required by Section 8.1.5.e. MHFResponse:An additional Special Permit has been requested. Hancock Comment: Hancock believes there is sufficient space to the south of the dumpster where the edge of pavement has a radius of 45 feet(assumedly for truck turning)that could be slightly expanded and squared off to accommodate a single box truck.We understand box trucks are used for daily delivery of donuts from regional bakeries. Any other location for trucks to park would impede the one-way circulation regardless of it being off-peak hours. 12. The freestanding sign depicted on the architectural elevation does not comply with Section 6.6.13. It exceeds 25 square feet and is higher than 8 feet above the ground.A Board of Appeals Special permit would be required. MHFResponse: Comment Acknowledged. Section 8.3.5 Additional Information Required: 1. Zoning Section 8.35.d requires that an Architect registered in the Commonwealth of Massachusetts stamped all building elevations.An Architect Registered in New York stamps the elevations submitted. MHFResponse:Building Plans will be submitted to the North Andover Building Department and will be stamped by a Registered Architect in Massachusetts. Hancock Comment: The By-law requirement pertains to submission to the Planning Board. This is an open item. 2. Section 8.5.e.i—LOCATION MAP: states, "A location map showing surrounding roadways and land uses adjacent to the site(1"=1500'). Location Map should show at least one intersection of two existing Town roadways." The `Locus Plan' contained within the Proposed Site Plan, is at a scale of 1"=300' and does not adhere to the requisite scale of 1"=1500' set forth in this section. MHFResponse:Plan has been revised. Hancock Comment: We are satisfied with the response. 3. Zoning Section 8.5.e.xvii—LIGHTING FACILITIES states"Identification of the proposed illumination, indicating the direction and the degree of illumination offered by the proposed lighting facilities, including an example of the light fixture to be used." It is unclear from the submitted plans whether the type, direction and degree of illumination conform to the guidelines set forth in Section 6.0—Signs and Outdoor Lighting Regulations of the Zoning Bylaw. MHFResponse:A lighting plan showing lighting levels, direction of lighting and lighting fixtures have been submitted. Hancock Comment: We are satisfied with the response. 4. Section 8.3.5.e.xxi—UTILITIES: states"All utilities, including water line locations, sewer line locations and profiles, and storm drainage systems."A Marlborough, MA Danvers, MA 315 Elm Street 185 Centre Street www.hancockassociates.com profile of the proposed sewer line running 248 feet within Osgood Street should be provided.As stated earlier missing information regarding the drainage along this route should be obtained. The Applicant should consider a"dog-house"style manhole at the existing sewer line to allow for continued flow during construction. The Applicant should also provide copies of the easement documents for this sewer line as it enters private property on the south side of Osgood Street. Lastly,the Town Engineer should be consulted with regard to construction specifications for work within Osgood Street. MHFResponse: The plan has been revised. Hancock Comment: We are satisfied with the response. General Engineering Review Comments 1. Hancock understands Lisa Eggleston is reviewing the design of the stormwater management system. We defer to Ms.Eggleston's regarding this matter. MHFResponse: Comment Acknowledged. 2. The applicant should indicate areas of snow storage on the plan. MHFResponse: The plan has been revised. Hancock Comment: We are satisfied with the response. 3. The landscaping plan should show all proposed underground utilities to ensure that no conflicts exist. MHFResponse:No conflicts exist. Hancock Comment: We are satisfied with the response. 4. The Applicant should investigate consolidation of the two proposed curb cuts into a single curb cut.Additionally,the slope of the entrance exceeds 8%. The Applicant should also investigate softening these grades given the nature of Osgood Street and the anticipated speed of vehicles turning into the site. MHFResponse: The curb cuts have been revised to have an entrance and exit and the grade on the driveways has been reduced to S% at the entrance and 6.5% at the exit. Hancock Comment: We are satisfied with the response and change to the plan. 5. The curb radii should be a minimum of 30' to support right turns into the site and right turns out of the site. MHFResponse: The plan has been revised. Hancock Comment: We are satisfied with the response. 6. The Applicant should investigate providing parking for patrons leaving the drive- through for instances of order problems or delays. MHFResponse:Parking for patrons of the drive thru is not necessary for this type of facility. Hancock Comment: We are satisfied with the response. 7. Queuing should be adjusted to provide 20' per vehicle. Queuing for only four to five vehicles is provided from the order board back prior to impacting parking spaces. The Applicant should consider designating several impacted spaces as employee parking. Marlborough, MA Danvers, MA 315 Elm Street 185 Centre Street www.hancockassociates.com MHFResponse: The queuing has been verified by the traffic consultant and we will designate the spaces at the end of the drive thru queue as employee spaces. Hancock Comment: Hancock defers to MDM Transportation for review of the additional information submitted by the Applicant regarding the queuing. 8. Soil testing in support of the stormwater management system should be added to the plans. MHFResponse: The plan has been revised Hancock Comment: We are satisfied with the response. 9. The Applicant should consider the inclusion of a grease trap given the proposed restaurant use. Hancock understands the proposed shop's current practice limits food preparation on site, however this is subject to change. Given the restaurant use,the Board of Health should be consulted with regard to the inclusion of a grease trap. MHFResponse:Dunkin Donuts uses an internal grease trap for this type of facility and will adhere to whatever requirements that the Board for health dictates for this type of facility. Hancock Comment: We are satisfied with the response. 10. The Applicant is proposing a segmental block wall requiring geo-grid reinforcement in close proximity to a proposed infiltration system. The Applicant should confirm there are no conflicts. Similarly, a retaining wall is proposed at the back of the proposed dumpster area within 3' of the property line. The Applicant should confirm the geo-grid(if required)can be installed within the property limits. MHFResponse: The proposed retaining walls for the site will be a landscape type block.All the walls are less than four feet in height and therefore will not require any type of geo grid reinforcement. Hancock Comment: We are satisfied with the response. 11. The detail of the trash enclosure needs to be coordinated with the retaining wall mentioned above. MHFResponse:A detail of the retaining wall trash enclosure typical section has been included. Hancock Comment: We are satisfied with the response. 12. Regarding the Erosion and Sedimentation Control Plan,the stockpile area should be relocated out of the buffer zone to the wetlands and protection from over- compaction of soils within the proposed infiltration area should be provided. Catch basins in Osgood Street within the area of the proposed sewer should be noted to receive Siltsacks. MHFResponse: The stockpile area has been relocated out of the buffer zone.A note regarding the addition of silt sacks in the basins along Osgood Street has been added to the Construction sequence. Hancock Comment: We are satisfied with the response. 13. Light levels on the sidewalk at the proposed appear too low. It is recommended at least 1.0 foot-candle is provided within pedestrian areas. Marlborough, MA Danvers, MA 315 Elm Street 185 Centre Street www.hancockassociates.com MHFResponse: The lighting plan is sufficient for the use and does not take into account the lighting coming from inside the store which provides additional lighting in the sidewalk areas. Hancock Comment: Hancock believes the area of low light is far enough from the building such that internal lighting may not be sufficient to address the issue. A sidewalk bollard light may be necessary to address the issue. Review Criteria/Design Guidelines 1. The Applicant states that the project will be connected to municipal sewer and water as evidence that the municipal system has the ability to serve the project. More detail with regard to available system capacity and actual project demands should be provided. MHFResponse:A typical Dunkin Donuts of this size will generate 380 gpd. The flow rate can be accommodated by the existing 8"sewer line in Osgood Street. Hancock Comment: The Applicant should verify that there are no existing issues with the sewer in the area. 2. The Applicant states that the architectural style is in harmony within the context of the surrounding businesses and that the scale of the building is consistent with that of surrounding buildings but provides no support. MHFResponse: The building style of the proposed Dunkin Donuts is New England Colonial Style which is consistent with the architectural design of the Treadwell's site across and north of this site and with the proposed development located directly across form the site. Hancock Comment: Hancock defers to the Planning Board with regard to this response. The Applicant now complies with the information submission requirement. 3. The Applicant states that electric,telephone and cable utilizes will be placed underground but shows proposed overhead lines crossing Osgood Street to a proposed pole on site. MHFResponse: The power company will require overhead lines from the existing pole line to the site and the will go underground from there. Typically the power company will not place service lines underground across public streets. Hancock Comment: We are satisfied with the response. 4. As discussed earlier the Applicant is proposing two curb cuts. The Applicant is required to minimize curb cuts to reduce turning movements and hazardous exits and entrances. See previous discussion. We believe the Applicant has addressed the majority of our prior concerns related to the review of site related issues.A letter commenting on the response to the Traffic Study response will be sent under separate cover.

The North Andover Bylaw has a clear route to Marlborough, MA Danvers, MA 315 Elm Street 185 Centre Street www.hancockassociates.com impervious reduction through land-banked parking. We do not agree with the Applicant's argument regarding this defeating the purpose. While MHT remains "firm"regarding their conviction to the parking provided,the design leaves no room for error. 2. We defer to Ms.Eggleston regarding drainage issues. 3. Architectural plans signed by a registered architect are a By-law requirement pertaining to submission to the Planning Board.The Board can choose to waive this submission requirement. 4. Hancock's concern with the adequacy of pedestrian lighting has been addressed. 5. The Sewer Department has commented on the existence of a sewer stub and the 12"water main in Osgood Street. The letter is silent with regard to adequacy of these utilities. We assume if there was an issue the Public Works would have mentioned their concern. There remains a difference of opinion regarding the parking. The Planning Board will have to address directly with the Applicant.A letter commenting on the response to the Traffic Study response will be sent under separate cover.

With respect to section g,Reduction in Parking,the required parking for the site is calculated at 27 spaces and 19 spaces'have been provided. We are requesting a reduction of eight(8) spaces which represents only 30%reduction of the required amount,which is less than the 35%which would be allowed under this section of the By-Law. We believe that the reduction is appropriate since for this type of fast food restaurant(coffee shop),more than 50% of the business is conducted thru the drive thru which is much more than you might find for a more food driven type of restaurant. Additionally a more common type of application for parking requirement is based on seats. This facility will have 25-26 seats in addition to the takeout. Using a standard rate of one space per two seats,plus employees,this site would require 13 spaces for the seating and 5 spaces for employees or a total of 18 spaces. Additionally, we have conducted a Parking Demand Evaluation Analysis based on a similar type facility in Methuen, Massachusetts. A copy of the excerpt from the Response Comments to MDM's review of the traffic study including the actual Parking Demand data is included for your review and consideration. ENGINEERS PLANNERS SURVEYORS 7Z FI Design Design Consultants, Inc. With respect to section b, Modification of Parking/Loading Area Design Standards,we are requesting that the site not be required to have a specific designated loading area of the dimensions required given the nature of this type of development.- Typically,this type of use has deliveries made on off peak hours and off loads the products onto hand trucks and wheeled into the rear entrance of the building. There is no formal loading dock area that is necessary given the nature of the type and size of deliveries that are made to the site. Additionally, deliveries are not made but every few days and at off peak business hours, generally in the area to the rear of the drive thru in the by-pass lane of the site. We respectfully request that the Board make a finding as to the adequacy of the parking and loading areas for this site and issue a Special Permit as filed for this project. If you should have any questions,please contact our office at your convenience. Very Truly Yours, MHF Design Cf6ins ts,I PC ark S. rosy, P.E. Principal RESPONSE TO COMMENTS Proposed Dunkin'Donuts—North Andover,Massachusetts signals provide gaps in the traffic stream which allow motorists more opportunity to enter and exit driveways and curb cuts along Osgood Street. From this, it can be concluded that the proposed Dunkin' Donuts development is not expected to have a significant impact on the operations of Osgood Street. Site Circulation Comment: MDM has reviewed the Site Plan and has the following comments: • In order to reduce conflict points along Osgood Street and to eliminate the conflict between exiting vehicles and patrons destined to the drive-thru, the proposed northerly driveway should be designed as an enter-only driveway. • The pavement markings designating the drive-through lane should be extended to and terminated at the parking field so that motorists can clearly differentiate between the drive-thru lane and the by-pass lane. • Parking stalls that could be obstructed by vehicles stacked in the drive-thru lane should be designated for employee parking so as to limit the frustration to patrons. Response: As recommended by MDM and as commented on by MassDOT, the northern site driveway has been modified to an entrance-only driveway. The updated Site Plan has revised the parking field, as well as the drive-through lane and by-pass lane area. With these modifications, the pavement markings have been extended to be visible from the parking field. The Applicant is willing to designate employees to park in the stalls that could be obstructed by vehicles stacked in the drive-through lane. If the Town wishes, EMPLOYEE PARKING signs can be installed. On-Site Parkin Comment: MDM notes that a parking study was not conducted as part of the TMS. Given that the Applicant does not meet the zoning requirements for the number of required parking spaces, MDM recommends that the Applicant conduct a parking study to determine if the number of proposed parking spaces will adequately accommodate anticipated patron demand. The analysis should include parking data collected at a local, freestanding Dunkin' Donuts restaurant. 12066 RTC Memo 121112 Page 13 '.. RESPONSE TO COMMENTS Proposed Dunkin'Donuts—North Andover,Massachusetts Response: As requested, a parking demand evaluation was conducted at an existing freestanding Dunkin' Donuts restaurant (3,527 square feet) located at 450 Broadway in Methuen, Massachusetts. This facility was chosen as Broadway has similar characteristics as Osgood Street in that they both provide two lanes in each direction, directional flow is separated by a double-yellow centerline, and they have comparable daily traffic volumes. According to historical traffic-volume data(South Broadway north of Lawrence Road) carried approximately 22,000 vehicles per day in 20112 and the TIAS depicted that Osgood Street carried approximately 25,660 vehicles per weekday. The New Hampshire Department of Transportation historical traffic-volume data is provided in the Appendix. A parking demand survey was conducted at the Methuen Dunkin' Donuts parking lot during the weekday AM peak period (7:00 AM to 9:00 AM) and the Saturday midday peak period (11:00 AM to 2:00 PM) in 15-minute increments. The time periods selected for evaluation were determined based on discussion at the November 19ffi meeting with the Town of North Andover's traffic peer review consultant, Mr. Daniel J. Mills, P.E., PTOE, of MDM. The survey included noting the number of parked vehicles and the number of available parking spaces. The observations were conducted on Thursday, December 6, 2012, and on Saturday, December 8, 2012. The parking demand survey data for the parking areas are provided in the Appendix. Table 3 summarizes the total number of occupied parking spaces during each 15-minute interval within the Methuen Dunkin' Donuts parking lot. As shown in Table 3, the peak parking demand for the weekday AM peak period was found to be 13 vehicles and occurred at 7:45 AM and at 8:45 AM, and the peak parking demand for the Saturday midday peak period was found to be 17 vehicles and occurred at 11:00 AM. Based on these observations, there were 18 remaining available parking spaces (31 total provided minus 13 occupied) during the weekday AM peak demand period and 14 remaining available parking spaces (31 total provided minus 17 occupied) during the Saturday midday peak demand period. A graphical representation of the parking survey results for the Methuen Dunkin' Donuts parking lot is provided in the Appendix. 2 New Hampshire Department of Transportation Traffic Volume Report; 2011; NH 28 (South Broadway) north of Lawrence Road. 12066 RTC Memo 121112 Page 14 RESPONSE TO COMMENTS Proposed Dunkin'Donuts—North Andover,Massachusetts Table 3 PARKING DEMAND SURVEY— Methuen Dunkin' Donuts Parking Lot Thursday,December 6,2012 Saturday,December 8,2012 Number of Number of Start Time Occupied Spaces Start Time Occupied Spaces 7:00 AM 6 11:00 AM 17 7:15 8 11:15 16 7:30 9 11:30 10 7:45 13 11:45 4 8:00 11 12:00 PM 8 8:15 9 12:15 4 8:30 12 12:30 6 8:45 13 12:45 8 1:00 8 1:15 9 1:30 7 1:45 8 These parking observation data reveal that the parking areas are only ±42 percent utilized (13 occupied/31 total) during the weekday AM peak parking demand period and only ±55 percent utilized (17 occupied/31 total) during the Saturday midday peak parking demand period. Therefore, the observations suggest that the proposed 19 parking spaces to be provided on the site would accommodate the peak parking demands of the Dunkin' Donuts restaurant. Mitigation Measures Comment: MDM notes that no off-site mitigation is proposed in the TIAS. We recommend that the Applicant provide off-site mitigation to allow for enhanced access/ egress for vehicles and pedestrians and to address the traffic impacts and safety issues related to the project. In addition, MDM recommends that the Applicant undertake some level of traffic signal improvements at adjacent intersections should MassDOT's traffic signal betterment project be delayed or put on hold.

These plans have been revised based on comments from Hancock Associates dated November 9, 2012. Based on those comments we offer the following: Parcel/Zoning Comments: 1. The deed is from 1950 and describes the properly at that time. In 1961 there was as highway taking along Route 125,hence the difference in the plan versus the deed. This has no affect on grandfathering issues for this project. 2. The I-2 and B-s line have been shown on the revised plans. 3. Comment acknowledged. 4. Comment acknowledged. 5. We have revised the request for a Special Permit under Section 8.1.8g and believe based on the attached information we meet the criteria for filing for a Special Permit under this section. See attached request and supporting documentation. 6. We stand by our request for waivers on these items. 7. A separate Watershed Special Permit application has been filed for a portion of the property based on our meeting with the Town's Environmental Consultant, Lisa Eggleston. 8. A 6 foot high stockade fence has been shown on the Landscape and Lighting Plan. 9. The plan shows handicap spaces which will provide equal access to the front door as well as to the rear door of the facility which is primarily for the use of the employees. 10. The proposed driveway width has been revised to 25 feet. 11. A request for a Special Permit for Loading has been filed as part of the Special Permit request for parking as outlined in item 5 above. 12. Comment acknowledged. ENGINEERS ® PLANNERS ® SURVEYORS MHF Design Consultants, Inc. Section 8.3.5 Additional Information Required 1. Building elevations will be submitted to the North Andover building department and will be stamped and signed by a registered architect in Massachusetts. 2. The location map has been revised accordingly. 3. A lighting plan showing the lighting levels, direction of lighting and lighting fixture have been submitted. 4. The plan has been revised to indicate the use of a"doghouse" style of manhole for the sewer connection. The sewer connection is located in the ROW of Osgood Street and therefore no easements for connection into this line are necessary. General Engineering Review Comments 1. Comment acknowledged. 2. Snow storage areas are shown on the site plan. 3. As part of the design of the Landscaping we have made sure there are no conflicts with utilities,therefore do not need to show on the Landscape and Lighting Plan. 4. The curb cuts have been revised to have an entrance and exit and the grade on the driveways has been reduced to 5%at the entrance and 6.5%at the exit driveway. 5. Curb radii has been revised to 309 feet for the right turns into the site and out of the site. 6. Parking for patrons of the drive thru is not necessary for this type of facility. 7.

Dunkin Donuts uses an internal grease trap for this type of facility and will adhere to whatever requirements that the Board of Heath dictates for this type of facility. 10. The proposed retaining walls for the site will be a landscape type block. All the walls are less than four feet in height therefore will not require any type of geo-grid reinforcement. 11. A detail of the retaining wall and trash enclosure typical section has been included. 12. The stockpile area has been relocated out of the buffer zone. A note regarding the addition of siltsacks in the basins along Osgood Street has been added to the Construction sequence. 13. The lighting plan is sufficient for the use and does not take into account the lighting coming from inside the store which provides for additional lighting in the sidewalk areas. Review Criteria/Design Guidelines 1. A typical Dunkin Donuts site of this size will generate approximately 380 gpd. This flow rate can be accommodated by the existing 8" sewer line in Osgood Street that is being tied into. 2. The building style of the proposed Dunkin Donuts is New England Colonial Style which is consistent with the architectural design of the Treadwell's site across and north of this site and with the proposed development located directly across the site. lila Design Consultants, Inc. 3. The power company will require overhead liens from the existing pole line to the site and then will go underground from there.
