July 26, 2019 Mr. Christopher Duke Becker Morgan Group, Inc. 250 South Main Street Suite 109 Newark, Delaware 19711 Dear Mr. Duke: The enclosed Traffic Impact Study (TIS) review letter for the proposed KH – Angola (Tax Parcel 234-11.00-56.02, 56.03, 56.06, 56.09) development has been completed under the responsible charge of a registered professional engineer whose firm is authorized to work in the State of Delaware. They have found the TIS to conform to DelDOT’s Development Coordination Manual and other accepted practices and procedures for such studies. DelDOT accepts this review letter and concurs with the recommendations. If you have any questions concerning this letter or the enclosed review letter, please contact me at (302) 760-2167.

Brestel Project Engineer DelDOT Division of Planning P.O. Box 778 Dover, DE 19903 RE: Agreement No. 1773 Traffic Impact Study Services Task No. 1A Subtask 26A – KH Angola Dear Mr. Brestel: McCormick Taylor has completed its review of the Traffic Impact Study (TIS) for the KH Angola development prepared by Becker Morgan Group, Inc., dated June 2019. Becker Morgan Group prepared the report in a manner generally consistent with DelDOT’s Development Coordination Manual . The TIS evaluates the impacts of the KH Angola development, proposed to be located on the southeast corner of the intersection of Delaware Route 24 and Robinsonville Road / Angola Road (Sussex Route 277), in Sussex County, Delaware. The proposed development would consist of a 3,500 sf convenience store with gas pumps. Two access points are proposed; one full access along Angola Road and one rights-in/rights-out access along Delaware Route 24. Construction is anticipated to be completed by 2022. The subject land consists of four parcels totaling approximately 3.5 acres. The land is currently zoned AR-1 (agricultural residential) within Sussex County, and the developer seeks a conditional use approval to permit the proposed land use. DelDOT currently has one active project within the study area. DelDOT’s Hazard Elimination Program (HEP), formerly Highway Safety Improvement Program (HSIP), includes improvements at the intersections of Delaware Route 24 and Camp Arrowhead Road (Sussex Road 279) / Fairfield Road, and Delaware Route 24 and Robinsonville Road / Angola Road. Planned improvements at both intersections are part of State Contract No. T201200902. The improvements at the intersection of Delaware Route 24 and Robinsonville Road / Angola Road will include widening the westbound Angola Road and eastbound Robinsonville Road approaches to provide separate left-turn, through, and right-turn lanes. The northbound and southbound Delaware Route 24 approaches will also be widened to provide separate left-turn, through, and right-turn lanes. In addition, the left-turn and right-turn lanes will be extended on all approaches to meet storage requirements. This HEP project is currently in design, with right-of-way acquisition starting in the fall of 2019 and construction starting in the spring of 2021. It is also noted that the proposed development is located within the boundary of the Henlopen Transportation Improvement District (TID) as presently contemplated by Sussex County and DelDOT. The TID is a planning concept that seeks to proactively align transportation infrastructure spending and improvements with land use projections and future development within the designated district. Based on our review, we have the following comments and recommendations: The following intersection exhibits level of service (LOS) deficiencies without the implementation of physical roadway and/or traffic control improvements: Existing Traffic Intersection Situations for which deficiencies occur Control Delaware Route 24 and 2019 existing Saturday (case 1); Robinsonville Road / Signalized 2022 AM, PM & Saturday without and with Angola Road KH Angola (case 2 & 3) For the projected future LOS deficiencies at the intersection of Delaware Route 24 and Robinsonville Road / Angola Road, it is noted that the deficiencies are only anticipated to occur without DelDOT’s Delaware Route 24 at Robinsonville Road / Angola Road Intersection Improvements Project. When analyzed with the improvements planned as part of that project, future LOS is acceptable (either without or with the KH Angola development). It is also important to note that the DelDOT project is currently projected to go to construction in spring of 2021, and the KH Angola project is anticipated to be complete in 2022. Should the DelDOT project be delayed, or should the KH Angola project move forward sooner than expected, coordination between the developer, DelDOT, and Sussex County is critical to ensure acceptable design and operations of the intersection and site accesses as the KH Angola project is constructed and opens to traffic. This could potentially involve additional improvements by the developer that are not currently anticipated or recommended. Should the County choose to approve the proposed development, the following items should be incorporated into the site design and reflected on the record plan by note or illustration. All applicable agreements (i.e. letter agreements for off-site improvements and traffic signal agreements) should be executed prior to entrance plan approval for the proposed development. KH Angola July 25, 2019 Page 2 1. The developer should construct Site Access A on Angola Road. The proposed configuration is shown in the table below. Approach Current Configuration Proposed Configuration Northbound Does not exist One shared left-turn/right-turn lane Site Access A Eastbound One through lane and One through lane Angola Road one right-turn lane One left-turn lane (continuing to the downstream signalized intersection), Westbound One through lane one through lane, and Angola Road one right-turn lane (for the downstream signalized intersection) Note that proposed configuration above reflects the anticipated future condition in which the westbound Angola Road left-turn lane and right-turn lane for the downstream signalized intersection at Delaware Route 24 would extend beyond the Site Access A location. These and other improvements at the signalized intersection are planned as part of DelDOT’s Delaware Route 24 at Robinsonville Road / Angola Road Intersection Improvements Project (see project description on Page 1, and Item No. 3 below). Initial recommended minimum turn-lane lengths (excluding tapers) of the separate turn lanes at Site Access A are listed below. The developer should coordinate with DelDOT’s Development Coordination Section to determine final turn-lane lengths and other design details during the site plan review process. Approach Left-Turn Lane Right-Turn Lane Northbound N/A N/A Site Access A Eastbound N/A 190 feet * Angola Road Westbound 160 feet ** N/A Angola Road * Turn-lane length based on DelDOT’s Auxiliary Lane Worksheet , although distance may be limited by site constraints and proximity to the upstream intersection. ** Turn-lane length is based on DelDOT’s Auxiliary Lane Worksheet . Length shown is from the Site Access A location to the beginning of the full-width portion of the turn lane, which may not match the current turn lane design of DelDOT’s intersection improvements project. Note that the turn lane will continue past Site Access A to the downstream signalized intersection. KH Angola July 25, 2019 Page 3 2. The developer should construct Site Access B on Delaware Route 24. The proposed configuration is shown in the table below. Approach Current Configuration Proposed Configuration One left-turn lane (for the downstream signalized intersection), Northbound One through lane one through lane, and Delaware Route 24 one right turn lane (continuing to the downstream signalized intersection) Southbound One through lane One through lane Delaware Route 24 Westbound Does not exist One right-turn lane Site Access B The developer should also construct a concrete median on Delaware Route 24 from the stop bar at the Robinsonville Road / Angola Road signal to a point sufficiently far enough south of Site Access B to physically restrict the lefts-out and lefts-in movements at Site Access B. The developer should also erect “No Left Turn” signs (MUTCD R3-2) on the southbound
