Village of Marvin North Carolina DATE: June 16, 2015 TO: Chairperson and Planning Board Members FROM: Lisa Thompson, Administrator/Senior Planner SUBJECT: TIA Review and Road Improvement Recommendations Attached is the road improvement summary agreed upon by both NCDOT and the Village Traffic Engineer. In addition staff has attached email exchanges since February that led up to the final list of traffic improvements. Kimley-Horn, the applicant’s traffic engineer, is in the process of updating the land uses in the TIA to match the plan/uses that Regency Centers has for the project. This will include one fastfood restaurant. It was recommended by the Village’s traffic engineer that the Board place a condition on the plan requiring the uses on the plan match the TIA and that the amount of trips being generated by the current land uses will not go higher. If they do, the applicant will need to revise the TIA at that time to include the increase in trips and any additional improvements based on the new TIA. Attached 1. Improvement Summary 2. Email exchange and reviews between Village of Marvin and NCDOT 1.

Marvin Gardens Transportation Improvements 2. Email Exchange and Review by NCDOT and The Village of Marvin NCDOT COMMENTS FROM 2/9/2015 Below are my comments on this TIA. If you do not have any additional comments than these can be sent to Jonathon Guy with Kimley Horn. I talked with Scott and Louis about this and they want to be sure that the approved driveway permit (in addition to approved TIA) clearly indicate that the signal on NC 16 at Access 1 will be removed when NC 16 is widened. Lisa – Can the Village get the plat to also clearly state that the signal on NC 16 at Access 1 will be removed when NC 16 is widened? NC 16 (Providence Rd) @ Ennis Rd Good with recommendations NC 16 (Providence Rd) @ New Town Rd PM Peak LOS – The following drops in LOS or increases in delay are not mitigated for with recommended improvements. o NB Approach drops in LOS from C to D Storage Lengths – The following turn lanes see an increase in storage needed from 2017 background to 2017 build and currently are not recommended to be increased. Each turn lane should be increased in storage length to accommodate 95th queue length for 2017 build with improvement conditions. o EB Left – storage increased to 350’ o WB Left – storage increased to 275’ o NB Left – storage increased to 375’ o SB Left – storage increased to 300’ Eastbound right turn lane – This turn lane was recommended to have 75’ storage. We will require the storage to begin at the previous RI/RO driveway with the taper all being prior to this driveway. Southbound right turn lane – This turn lane was recommended to have 50’ storage. We will require the storage to begin at the previous RI/RO driveway with the taper all being prior to this driveway. NC 16 (Providence Rd) @ Bonds Grove Church This intersection was analyzed with a northbound left turn, southbound right turn and a traffic signal in the 2017 build and 2017 build with improvements conditions. The NCDOT does not currently have a funded project to make any of these improvements nor are they currently required improvements by any development. As such it can’t be assumed these improvements will be in place for the 2017 conditions. This intersection will need to be relooked at not assuming these improvements have been made. New Town Rd at Crane Rd Analysis done this intersection shows there being a westbound right turn lane existing at intersection. This right turn lane does not exist today. Analysis should be redone removing this from existing conditions. All comments below are based on existing analysis and may change once analysis is redone removing this lane from existing conditions unless it becomes a developer recommended improvement. AM Peak LOS - The following drops in LOS or increases in delay are not mitigated for with recommended improvements. These drops still occur even after a longer cycle length was used in 2017 build with improvement conditions. The other two approaches saw in an increase in LOS. Likely due to longer cycle length. o EB Approach drops in LOS from B to C o WB Approach drops in LOS from C to D Storage Lengths – The following turn lanes see an increase in storage needed from 2017 background to 2017 build and currently are not recommended to be increased. Each turn lane should be increased in storage length to accommodate 95th queue length for 2017 build with improvement conditions. o WB Left – storage increased to 225’ o NB Left – storage increased to 300’ New Town Rd @ Ennis Rd/Broomes Old Mill Rd Good with recommendations NC 16 (Providence Rd) @ Woodmont Dr Good with recommendations NC 16 (Providence Rd) @ Site Access 1 Traffic volumes for intersection have been shown to meet warrants. TIA should indicate that this signal is temporary and will be removed once NC 16 has been widened to multilane divided roadway. Fiber interconnect shall be installed between this signal and the signal at New Town Rd. Coordinated timings plans shall be developed and ready to implement before this signal is put into full operation. Span and ground mounted signs shall be installed for this signal on the side street approaches indicating that this is a temporary signal. Though the traffic signal will be removed from this intersection when NC 16 is widened there has already been talk about a 4th leg being added for additional development. Should this occur it will be preferable that the lane configuration on each side street approach be a left only and a thru/right. It is currently being proposed that the westbound approach be built with a pocket right turn lane. To accommodate a possible future 4th leg the westbound approach should be built with a pocket left turn lane with 250’ of storage. 250’ of internal protected storage should be provided (measured from the existing ROW line) since this will be a signalized access point. A right turn lane will be required on northbound NC 16. Storage length to be determined by Synchro/Sim Traffic analysis. The westbound approach is shown that it will be operating at a LOS F during the AM and PM peaks. Required northbound right turn lane may increase this LOS or at least decrease delay. NC 16 (Providence Rd) @ Site Access 2 A median is recommended in the TIA on NC 16 to make this access point RI/RO. There is an existing full movement drive almost directly across the street from this access point. This will make installing the concrete median on NC 16 a challenge if the idea is to leave this access full movement. 100’ of internal protected storage should be provided (measured from the future ROW line). New Town @ Site Access 3 Storage Lengths – The westbound left turn 95th queue is 77’ and Max Queue is 149’. Only 50’ of storage is recommended for this left turn lane. This turn lane should be built with a minimum of 150’ of storage. 100’ of internal protected storage should be provided (measured from the ROW line). Concrete median on New Town Rd should be installed from NC 16 through Site Access 3 and to Site Access 4. New Town Rd @ Site Access 4 Storage Lengths – The westbound left turn 95th queue is 52’ and Max Queue is 148’. Only 50’ of storage is recommended for this left turn lane. This turn lane should be built with a minimum of 150’ of storage. Concrete median on New Town Rd should be installed from NC 16 through Site Access 3 and to Site Access 4. Due to the traffic signal for Access 1 on NC 16 being a temporary signal we would prefer for the developer to modify site plan and install a traffic signal at this intersection instead. This location could remain signalized even after NC 16 is widened.

UPDATED NCDOT COMMENTS FROM 5/18/2015 NC 16 @ Bonds Grove Church I would like to get how much they will be contributing to this intersection nailed down before we approve the TIA. We also need to work out who will be taking this money. Marvin or Waxhaw. NC 16 @ Driveway 1 The TIA states a westbound right turn lane should be constructed. However, we have asked that a westbound left turn lane be constructed so that when a 4th leg is added the right most lane can be converted to a thru/right. The TIA needs to indicate that this signal shall be connected to the signal at New Town through fiber and that the developer will be responsible for the development of coordinated timings plans for these two signals. Since this is a temporary signal and we are requiring them to install signs that say as much this should be indicated in the TIA. A general sentence that states that the developer is aware that this signal will be removed when NC 16 is widened and that signs indicating this is a temporary signal shall be installed alerting motorists of this. New Town Rd The median island mentioned in reference to Driveway 3 should extend between NC 16 and Driveway 4. New Town @ Crane Rd The wording for this improvement should read “Install protected/permitted phasing for the northbound and westbound left turn movements at the existing signalized intersection.” VILLAGE OF MARVIN TRAFFIC ENGINEER COMMENTS FROM 5/28/15 General: The Right Turn on Red function at signalized intersections is typically not recommended to be activated per NCDOT Congestion Management review standards. The “Lost Time” factor at the signalized intersections appears to be adjusted to 4.0 seconds per phase. The Lost Time is recommended to be adjusted to 5.0 seconds per phase per NCDOT Congestion Management review standards. According to the CRTPO Transportation Plan, Providence Road (NC 16) is considered a boulevard and New Town Road is considered a major thoroughfare. These roads were both considered major thoroughfares in the most recent CRTPO Thoroughfare Plan. The typical section for both roadways will be, at a minimum, four‐ lane divided roadways with wide outside lanes and sidewalks. This development should construct an additional lane along the frontage of the site on both Providence Road and New Town Road to be used as right‐turn lanes at all entrances. Trip Generation: According to the trip generation manual and NCDOT, the weighted average of the Peak Hour of Generator should be used to develop trips generated by a HighTurnover Sit-Down Restaurant (ITE 932). The study used the rates associated with the peak hour of the adjacent street traffic. Therefore, the trips expected to be generated by this land use were under counted. Trip generation should be revisited and adjusted to include specific uses for all of the outparcels. If the use of the outparcel is unknown, then the most intense use that can fit within that space must be used. This will ensure that the highest intensity use is studied to cover all possible uses. Typically, the most intense use for outparcels is a fast food restaurant, bank, or convenience store with fueling positions. Please supply a new trip generation table to be reviewed by the Village staff before completing any additional traffic analyses. Intersection of Providence Road (NC 16) & New Town Road: Consider installing overlap phases to the existing signal to serve the southbound and eastbound right turning vehicles. This will lower the delay expected to be experienced on these approaches. Intersection of Providence Road (NC 16) & Site Driveway #1: Consider installing overlap phases to the proposed signal to serve the northbound and westbound right turning vehicles. This will lower the delay expected to be experienced on these approaches. Due to the potential future widening of NC 16 as called for in Highway Program U-5769, consider designing the westbound approach of Site Driveway #1 to accommodate dual left turn lanes exiting the site when the road is widened. This would allow more green time to be given to NC 16 and reduce future queueing and delay. The driveway can be marked to allow only one exclusive left turn lane until NC 16 is widened. Intersection of Providence Road (NC 16) & Site Driveway #2: According to the standards set in the Policy of Street and Driveway Access to North Carolina Highways, an exclusive right turn lane is warranted on the northbound approach of NC 16. Intersection of New Town Road & Site Driveway #3: According to the standards set in the Policy of Street and Driveway Access to North Carolina Highways, an exclusive right turn lane is warranted on the eastbound approach of New Town Road. Intersection of New Town Road & Site Driveway #4: According to the standards set in the Policy of Street and Driveway Access to North Carolina Highways, an exclusive right turn lane is warranted on the eastbound approach of New Town Road. All of the other conclusions and recommendations made by the study are reasonable. It should be noted that the North Carolina STIP U-5769 which calls for Provenance Road (NC 16) to be widened to a multi-lane facility from SR 1316 (Rea Road Extension) to SR 1321 (Cuthbertson Road) is scheduled to begin Right-of-Way and Utility work in 2022 and Construction in 2024. Updated VOM Traffic Engineer Comments from 5/29/2015 Jonathan Guy from Kimley-Horn just called our office and talked to Jonathan Cate about the TIA for Marvin Gardens. They wanted to respond to some of the comments we made about the TIA. Here are the details of the conversation: 1) Trip Generation: they were worrisome about our comment to develop a new trip generation table for more intense uses. They believe that they cover the possible uses for the outparcels in the TIA and is reflected on the rezoning plan. We said that we would agree with their trip generation if they made the uses a condition of the rezoning. Therefore, we would be placing a trip cap on their overall site. If they eventually place uses on the site that are more intensive, they would have to update the TIA and could open themselves up to more improvements. If you would like for us to write that condition for the rezoning, we can do that. 2) Right turn on red and lost time for the signals: Jonathan from Kimley-Horn said that he worked out these details with the Division 10 office (Sean Epperson) since the Division does not typically send the TIA’s onto Congestion Management in Raleigh. It sounds like they worked out the details, but we have no documentation of any conversations or e-mails between Kimley-Horn and the Division. 3) They generally agreed with all of the other comments. UPDATED VOM Traffic Engineer Comments from 6/1/2015 1) We reviewed the traffic impact analysis (TIA) and rezoning plan. We indicated to the developer and traffic engineer that we wanted to see more intense uses in the TIA and rezoning plan and that they both needed to match each other. Our reasoning was that we wanted to be prepared for future conditions in case the uses on the site changed. 2) We had a discussion with the Traffic Engineer on Friday where he indicated that the uses on site are fixed and are reflected in the TIA. The discussion centered around the outparcels, as those are typically the unknown uses during a rezoning of a property. Those four uses for the four outparcels are as noted in the TIA: a. Bank with 3 drive-in lanes b. 2,000 SF Coffee Shop with drive-thru c. Convenience store with 8 fueling positions d. 5,000 SF High-turnover sit down restaurant Since the Traffic Engineer noted that these uses are fixed and match the rezoning plan, that we were acceptable of these uses IF AND ONLY IF they include these uses verbatim on the plan and commit to these uses as a condition of the rezoning. If the developer does commit to these uses, if they change any of these uses to a more intense use (i.e. a fast-food restaurant), then they would have to complete a brand new TIA before moving on with any planning (or design or construction) and be subject to further recommendations for improvements either on-site or off-site. If they commit to these conditions, then in our opinion, they are satisfying our concerns over the land uses. While they will be satisfying our review, because this is a rezoning, it is within your right to ask for what you believe. If you want them to include a fast-food restaurant in their TIA as a condition of the rezoning, you can ask. I believe that creating these conditions as we discussed on Wednesday in both text and pictures on the plan should cover all of the Village’s concerns for this rezoning. NCDOT’S REVIEW OF VOM Traffic Engineer Comments from 5/28 ‐ received 6/1/2015 General - The first two will have minimal impact on recommended improvements. In addition the allowance of right turns on red is something I allowed as it will be allowed in the field. For the 3rd comment I see no issue with this happening provided the pavement markings installed create pocket right turn lanes at all intersections. Trip Generation - These numbers have been approved by us. I have no issues with these comments being made now but would have been best had they been made when first draft of TIA was submitted last year. NC 16 @ New Town – These overlap phases will be required when signal design is done. NC 16 @ Site Driveway #1 – Again overlap phases will be required when signal design is done. Since this full movement signalized intersection will be removed when NC 16 is widened the NCDOT is not going to require this driveway to have the ability to go to dual lefts in the future. NC 16 @ Site Driveway #2 – No issues with this requirement of a right turn lane on NC 16. Page 30 of the TIA already recommends a 75’ right turn lane here however that recommendation did not make it to final recommendations on page 34. This should be corrected in revised TIA. I did not catch that this recommendation did not transfer to final recommendations in my earlier review. New Town Rd @ Site Driveway #3 – No issues with this requirement of a right turn lane on NC 16. Page 30 of the TIA already recommends a 100’ right turn lane here however that recommendation did not make it to final recommendations on page 34. This should be corrected in revised TIA. Again did not catch this recommendation not transferring to final recommendations. New Town Rd @ Site Driveway #4 – No issues with this requirement of a right turn lane on NC 16. Page 30 of the TIA already recommends a 50’ right turn lane here however that recommendation did not make it to final recommendations on page 34. This should be corrected in revised TIA. Again did not catch this recommendation not transferring to final recommendations. VOM TRAFFIC ENGINEER RESPONSE IN RED TO NCDOT COMMENTS 6/1/2015 General - The first two will have minimal impact on recommended improvements. In addition the allowance of right turns on red is something I allowed as it will be allowed in the field. For the 3rd comment I see no issue with this happening provided the pavement markings installed create pocket right turn lanes at all intersections. I agree with this. Trip Generation - These numbers have been approved by us. I have no issues with these comments being made now but would have been best had they been made when first draft of TIA was submitted last year. If NCDOT is approving the trip generation, then the Village should probably follow suit. My opinion is that the trip generation should still be a condition of the rezoning. That should satisfy any concerns from the Village for future more intense uses. If the TIA had an scoping MOU, this would have been decided before any TIA was submitted. Hence, the value of the MOU. NC 16 @ New Town – These overlap phases will be required when signal design is done. OK NC 16 @ Site Driveway #1 – Again overlap phases will be required when signal design is done. Since this full movement signalized intersection will be removed when NC 16 is widened the NCDOT is not going to require this driveway to have the ability to go to dual lefts in the future. As long as the developer knows this, we are OK with this. The driveway should have separate right and left turn lanes for egress as dictated in the TIA, but those two egress lanes are not yet shown on the plan. NC 16 @ Site Driveway #2 – No issues with this requirement of a right turn lane on NC 16. Page 30 of the TIA already recommends a 75’ right turn lane here however that recommendation did not make it to final recommendations on page 34. This should be corrected in revised TIA. I did not catch that this recommendation did not transfer to final recommendations in my earlier review. His last three sentences is the reason why we made the comment. The TIA said the turn lane was needed, but didn’t show the improvement in figure 9 that showed all of the recommended improvements. We agree that this needs to be corrected in the TIA. Also, if they show adding the additional lane on NC 16, this will be taken care of anyway. New Town Rd @ Site Driveway #3 – No issues with this requirement of a right turn lane on NC 16. Page 30 of the TIA already recommends a 100’ right turn lane here however that recommendation did not make it to final recommendations on page 34. This should be corrected in revised TIA. Again did not catch this recommendation not transferring to final recommendations. See site driveway #2 response. New Town Rd @ Site Driveway #4 – No issues with this requirement of a right turn lane on NC 16. Page 30 of the TIA already recommends a 50’ right turn lane here however that recommendation did not make it to final recommendations on page 34. This should be corrected in revised TIA. Again did not catch this recommendation not transferring to final recommendations. See site driveway #2 response.
