2 County of Loudoun Department of Planning and Zoning MEMORANDUM DATE: July 16, 2015 TO: FROM: Jackie Harlow, Project Manager Land Use Review Joseph Carter, AICP, CZA, GISP, Senior Planner Community Planning SUBJECT: SPEX , SPEX ; Vine & Branches Church and Childcare 1st Referral EXECUTIVE SUMMARY The Applicant, Vine & Branches Lutheran Church, requests Special Exceptions (SPEX) to permit a church and a child day care center. The subject property is comprised of two parcels of approximately acres and located within the TR-3LF (Transitional Residential 3; Lower Foley subdistrict) under the Revised 1993 Zoning Ordinance. The application proposes four buildings totaling approximately 76,000 square feet in floor area with an anticipated attendance of approximately 600 parishioners and enrollment of 250 children at the full build-out of the project. Two separate SPEX applications are requested due to the phasing of the development. The Applicant envisions that the initial phase of site development (Phase I) will construct an approximately 31,000 square feet building with classroom space to accommodate approximately 125 students and a multipurpose room that would be used for an indoor play area and weekend worship services. The subsequent phase (Phase II) will construct three additional buildings to expand the floor area an additional 45,000 square feet. The Applicant envisions Phase II to include an 18,000 square foot church sanctuary to accommodate up to 600 parishioners and a 27,000 square foot addition to the child care center to accommodate up to 250 students. The subject site is located in the Transition Policy Area, at the southwest corner of the intersection of Braddock Road (Route 705) and Gum Spring Road (Route 659). County policies envision residential uses, at 1 dwelling unit per 3 acres, and supportive nonresidential uses to develop in the Transition Policy Area. County policies support institutional uses and associated uses in the Transition Policy Area provided that development protects environmental resources and the development pattern provides a visual and spatial transition between the suburban development to the east and rural character of the County to the west. The application proposes uses of greater intensity than permitted by-right; therefore, Special Exceptions are necessary to permit the uses. Staff has evaluated the application based on the Revised General Plan policies for the Transition Policy Area, Green Infrastructure, and

3 SPEX , SPEX ; Vine & Branches Church and Childcare Community Planning 1st Referral July 16, 2015 Page 2 Design as it pertains to the subject site. Staff has provided recommendations to mitigate the impacts on adjoining properties. In addition, Staff recommends the Applicant submit a design that conforms to the County s policies for the Transition Policy area and that integrates the subject site within the surrounding development. BACKGROUND The subject site is located in the Transition Policy Area south of Braddock Road (Route 705), west of Gum Spring Road (Route 659). The residential communities of South Riding and Braddock Corner are located to the north (north of Braddock Road). The residential community Virginia Manor (approved as Seven Hills) is located to the south and west, west of Gum Spring Road. The Catholic High School is approved but unbuilt and located to the east and Ticonderoga Farms to the southeast. An active rezoning, Whitman Property South (ZMAP ) is proposed across from the subject site, at the southeast corner of the Braddock Road/Gum Spring Road intersection. The Whitman Property South application proposes development of a 35,010 square foot retail center including a convenience store with gas pumps and a Special Exception for a 12,800 square foot childcare center for up to 204 children. The Braddock Road Childcare Center, a 13,500 square foot facility with a maximum enrollment of 218 students, was recently approved at the July 8, 2015 Board of Supervisor Public Hearing. Staff notes property to the west, south of Braddock Road has not developed with residential densities envisioned within the Transition Policy Area (Kirkpatrick Farms, Kirkpatrick West, and Seven Hills). Property located to the north, south, and east of the subject property, with the exception of the Catholic High School site still retain the Transitional zoning of 1 dwelling unit per every 3 acres or 1 dwelling unit per every acre (See Zoning Map). The Seven Hills subdivision is approved with a density of 2.4 dwelling units an acre.

4 SPEX , SPEX ; Vine & Branches Church and Childcare Community Planning 1st Referral July 16, 2015 Page 3 A review of County GIS records and submission materials indicate elements of the County s Green Infrastructure are present on the subject site. The subject site encompasses wetlands, forest and vegetation resources onsite. None of the existing forest and vegetation onsite is proposed to be preserved. The applicant submitted various studies for Staff review regarding tree stand surveys, wetlands, endangered and threatened species, and heritage resources. As proposed, the application will impact wetlands and forest resources on the property. The Applicant submitted a Phase 1 Cultural Resources Survey dated April The study did not identify any archeological sites or architectural resources. No further work is recommended by the study and Staff concurs with the findings. A Natural Heritage Resource, the Bull Run - Chestnut Lick Stream Conservation Unit (SCU) is located within 1-mile downstream from the project site. Stream Conservation Units identify stream reaches that contain aquatic natural heritage resources. The Applicant submitted a letter from the Virginia Department of Conservation and Recreation (DCR) dated April 9, 2015 that recommends the implementation of, and strict adherence to, applicable state and local erosion and sediment control/stormwater management laws and regulations, establishment/enhancement of riparian buffers with native plant species, and maintaining natural stream flow. DCR states the current activity will not affect any documented state listed plants or insects. COMPLIANCE WITH THE COMPREHENSIVE PLAN The property is specifically governed by the Revised General Plan and 2010 Countywide Transportation Plan (CTP). The policies of the Loudoun County Bicycle and Pedestrian Mobility Master Plan (Bike/Ped Plan) also apply. The property is located in the Lower Foley subarea of the Transition Policy Area. The Transition Policy Area is envisioned as a distinct planning area to serve as a visual and spatial transition between the Suburban Policy Area to the east and the Rural Policy Area to the west (Revised General Plan, Transition Policy Area, text). The subject site is located in the Lower Foley subareas of the Transition Policy Area. The Transition Policy Area establishes residential densities and the scale of non-residential uses to provide a visual and spatial transition between the suburban and rural policy areas and to conserve the extensive Green Infrastructure resources present throughout the Transition Policy Area. The Lower Foley Subarea is planned for residential densities of 1 dwelling unit per 3 acres (0.33 du/ac) as well as non-residential uses that are compatible with the landscape such as golf courses, active recreation uses, kennels, nurseries and similar commercial uses, public and private schools and other compatible institutional uses. The proposal has been reviewed under the Revised General Plan Green Infrastructure policies of Chapter 5, Transition policies of Chapter 8, and the Design Guidelines of Chapter 11.

5 SPEX , SPEX ; Vine & Branches Church and Childcare Community Planning 1st Referral July 16, 2015 Page 4 ANALYSIS LAND USE The Applicant has requested SPEX applications to operate a child day care center and a church and associated uses with a seating capacity greater than 600 seats on the subject site of approximately 9.17 acres. The application lists two phases to construct a total of 76,000 square feet within four buildings, at a Floor Area Ratio (FAR) of At buildout the project will accommodate 600 parishioners and 250 children. Phase I is proposed to construct a 31,000 square foot building with classroom space to accommodate approximately 125 children and a multipurpose room that would be used for an indoor play area and weekend worship services. Phase II will construct three buildings that will add an additional 45,000 square feet to the site, for a total of approximately 76,000 square feet. The Applicant envisions the Phase II expansion to include an 18,000 square foot church sanctuary to accommodate up to 600 parishioners, a 11,000 square foot addition to the child care center to accommodate up to 250 children, and a 16,000 square foot addition for a multi-purpose facility. The SPEX plat does not identify the play area for the childcare center or specify the square footage of each use presented in Phase I; however, the Statement of Justification (SOJ) states the multipurpose room would be used for an indoor play area and weekend worship services (SOJ, p. 1). The application should also clarify whether the 11,000 square foot addition adds an additional 250 children to the childcare use or brings the total number of children for the childcare use to 250. Parking tabulations suggest the maximum number of children will be 250. The County s vision for the Transition Policy Area is for land uses to develop that provide a visual and spatial transition between the suburban development to the east and the rural development to the west. The Transition Policy Area is envisioned to develop as a unique and innovative blend of rural and suburban development features that fully integrate the elements of the Green Infrastructure, and establish natural open spaces as a predominant visual element and enhancement to the area s river and stream corridors (Revised General Plan, Chapter 8, Land Use Pattern General Policies, Policy 2). The Plan provides that nonresidential development in the Transition Policy Area will consist of uses that provide a transition from suburban to rural land uses, such as golf courses, active recreation uses, kennels, nurseries and similar commercial uses, public and private schools and other compatible institutional uses (Revised General Plan, Chapter 8, Community Design Policies, Policy 15). Non-residential uses will serve to define the Transition Policy Area as a unique planning area. The County will allow for a range of uses that are compatible with desired development patterns and the rural landscape and are at intensities not permissible within the Rural Policy Area (Revised General Plan, Chapter 8, Community Design Policies, Policy 16). New non-residential uses such as churches, which support residential development, should be organized within the community cores of villages at appropriate scales (Revised General Plan, Chapter 8, Land Use Pattern, text). However, large scale civic or institutional uses requiring more than 15 buildable acres, either individually or in a multipurpose facility, should be located on the periphery of an individual neighborhood or in core areas on roads that can accommodate the anticipated traffic volume (Revised General Plan, Chapter 8, Community Design Polices, policy 13c). Institutional uses and their associated uses are envisioned within the Transition Policy Area; however, a Special Exception is necessary because the Applicant requests to construct a religious assembly with a seating capacity greater than 300,

6 SPEX , SPEX ; Vine & Branches Church and Childcare Community Planning 1st Referral July 16, 2015 Page 5 up to 600, which is double the intensity permitted by-right. Although 15 buildable acres are not required for the proposed use, the intensity of the use may warrant the same location requirements, adjacent to a major collector or arterial, rather than internally within an individual neighborhood. The proposed building setbacks provide a greater separation of uses; however, additional separation or implementation of greater buffering plantings for the parking areas onsite would mitigate visual impacts from the intensity of the use, particularly along the northern property line where residential uses are located without additional onsite buffering. In addition to mitigating impacts of the use, the application should demonstrate compatibility with the adjacent properties and the Transition Policy Area design guidelines. Analysis Institutional uses and its associated uses proposed in this application are envisioned within the Transition Policy Area provided that they are developed at a scale that allows them to blend effectively (visually and spatially) into a rural landscape while serving both the suburban and rural populations. Staff has provided recommendations on the issue in the Design section of this referral. However, Staff recommends the Applicant mitigate the potential impacts from the proposed use in a manner that conforms to the Transition Policy Area by providing greater building and parking setbacks from the northern property line and a landscaping plan that installs increased buffering and/or screening along the perimeter of the site. Staff also recommends the SPEX plat idenitify the maximum number of children for the daycare use and maximum capacity of the religious assembly. DESIGN The Revised General Plan provides specific design guidance for development within the Transition Policy Area. The policies state that non-residential uses should blend both visually and spatially into a rural landscape and that individual non-residential buildings will not be greater than 40 feet in height and 150 feet in length (Revised General Plan, Chapter 11, Design Guidelines, D. Transition Policy Area Design Guidelines, Policy 3a and 3b.). The scale and the volume of the primary built mass and accessory elements should not dominate over the natural landscape. Policies further call for landscaping to shield buildings from roadways and placing parking behind buildings to prevent the creation of suburban style developments (Revised General Plan, Chapter 11, Design Guidelines, D. Transition Policy Area Design Guidelines, Policy 3c.). The structure footprint for Phase I, the childcare center and multi-purpose room, is approximately 287 feet in length with a depth of 200 feet. Two of the Phase II additions extend westward with internal outdoor space between the structures, which creates a courtyard design at full buildout. The addition to the southern wing of the Phase I building footprint adds 150 feet in depth and the church addition projects 120 feet eastward towards the roadway. The church addition creates articulation and breaks up the massing of Phase I to approximately 200 feet; however, consequently it also extends the length of the building to 350 feet on the facade facing Gum Spring Road, which exceeds the size recommended in the Transition Policy Area by more than double. In addition, the length and depth of the proposed structure creates a scale and massing that could dominate the natural landscape of the subject site as seen from Gum Spring Road, which is contrary to Transition Area policies.

7 SPEX , SPEX ; Vine & Branches Church and Childcare Community Planning 1st Referral July 16, 2015 Page 6 The SPEX plat identifies a 50% open space requirement, equal to 4.59 acres, per the zoning district. The majority of open space is adjacent to the proposed structures and encircled with surface parking. Analysis Combined with the intensity of the use and the absence of building design information, the building scale and site design of the application does not provide assurances that fully mitigate the visual and spatial impacts of the proposed use to conform to policies of the Transition Policy Area. To bring the application into better conformance with the Revised General Plan design guidelines set forth for the Transitional Policy Area, Staff recommends the Applicant: reduce the size of the buildings to no more than 150 feet in length, move the buildings further west away from Gum Spring Road, or re-orient the buildings to reduce the principal building mass from Gum Spring Road as much as possible, provide a landscaping plan that provides additional landscaping buffering around the perimeter of the site (preferably consisting of indigenous existing, mature vegetation), and shield the buildings from Gum Spring Road by utilizing the existing tree stands closest to Gum Spring Road and installing landscaping along the primary roadway frontage, reduce the prominence of parking areas from Gum Spring Road using landscaping and earthen berms or ideally remove parking areas from between the buildings and the roadway to avoid a suburban site character, and provide a building design that avoids continuous planes of building surfaces and reflects the rural character of Loudoun County using appropriate building materials. EXISTING CONDITIONS/ENVIRONMENTAL RESOURCES The Revised General Plan defines the County s Green Infrastructure as a collection of natural, cultural, heritage, environmental, protected, passive, and active resources that will be integrated in a related system (Revised General Plan, Chapter 5, Green Infrastructure Policies, Policy 1). Examples of green infrastructure components includes stream and river corridors, wetlands, forested areas, tree stands, steep slopes, greenways, trails, historic and archeological sites and other open spaces. Green infrastructure is the framework and unifying element that determines where and how development will occur within Loudoun County (Revised General Plan, Chapter 5, text). A central objective of the Transition Policy Area is to recognize, preserve, and enhance green infrastructure elements. A review of County records indicates forest resources and wetlands on the subject site. The applicant submitted various studies for staff review regarding tree stand surveys, wetlands, endangered and threatened species, and heritage resources. Wetlands The County supports the federal goal of no net loss to wetlands (Revised General Plan, Chapter 5, River and Stream Corridor Resources Policies, Policy 23). Wetlands perform several functions: they trap sediment, reduce nutrient loads, provide wildlife habitat, replenish groundwater, and attenuate flood waters. Plan policies call for the County to work with the US Army Corps of Engineers regional office to regulate wetlands outside of river and stream

8 SPEX , SPEX ; Vine & Branches Church and Childcare Community Planning 1st Referral July 16, 2015 Page 7 corridors (Revised General Plan, Chapter 5, River and Stream Corridor Resources Policies, Policy 13). In the event of an impact, compensatory mitigation (restoration, creation, enhancement, and preservation) could replace the loss of wetland functions in the watershed to meet the County s goal of no net loss to the existing acreage and functions of wetlands. The existing conditions sheet (Sheet 3) identifies an open water pond on the subject site; however, no Jurisdictional Determination has been submitted. Note 7 on the Cover Sheet references the delineation and states the site is subject to permits required by federal and state agencies prior to impacting these areas. Analysis Staff recommends a condition requiring wetland mitigation for impacts to wetlands. Stormwater The Revised General Plan calls for the protection of surface water resources from contamination and pollution; and preventing the degradation of water quality in the watersheds (Revised General Plan, Chapter 5, Surface and Groundwater Resources Text). Increases to impervious land cover due to development, such as rooftops and parking lots, can concentrate and increase the rate and volume of stormwater runoff from development. Developments typically convey stormwater runoff via gutters, sewers, and channels. The conveyed runoff can carry pollutants including litter, salts, oil, grease, and metals and impede the opportunity for water infiltration back into the ground. The hydrological impacts of increased runoff can result in detrimental impacts to groundwater replenishment, stream water quality and aquatic habitats. The County promotes water conservation through low impact development (LID) techniques (Revised General Plan, Chapter 5, Surface Water Policy 2). LID uses natural vegetation and small-scale treatment systems to treat and infiltrate rainfall close to the source. LID's goal is to mimic a site's predevelopment hydrology by using design techniques that infiltrate, filter, store, evaporate, and detain stormwater runoff. LID locates water quality measures at the closest possible proximity to proposed impervious areas. Some examples of LID techniques include: o Native landscaping enhanced through the routing of runoff through these areas; o Native-vegetated drainage swales for the movement and temporary storage of runoff; o Vegetated filter strips that slow runoff speed, trap sediment and pollutants, and provide additional water absorption; and o The collection of stormwater and rooftop runoff for irrigation use. The SPEX plat (Sheet 2) identifies a potential stormwater management (SWM) facility on the western portion of the subject site where the existing pond is located. Note 22 on the cover sheet states that stormwater management for the project site will be installed in accordance with the County s Facilities Standards Manual (FSM). The FSM also has LID techniques that could serve as the preferred approach for the treatment of stormwater. In an effort to reduce the amount of impervious surface, the Plan discourages parking that exceeds the requirements of the Zoning Ordinance.

9 SPEX , SPEX ; Vine & Branches Church and Childcare Community Planning 1st Referral July 16, 2015 Page 8 Analysis Staff recommends the Applicant commit to only providing parking spaces as required by the Zoning Ordinance and seek reductions with shared parking between uses. Staff recommends the applicant incorporate LID techniques on the subject site to mitigate the impacts of the proposed development. Staff recommends that the applicant commit to a number of LID techniques for the site. Forest Resources The Green Infrastructure policies call for the preservation, protection, and management of forests and natural vegetation for the various economic and environmental benefits that they provide, and for the submittal and approval of a tree conservation or forest management plan prior to any land development that demonstrates a management strategy that ensures the long-term sustainability of any designated tree save area (Revised General Plan, Chapter 5, Forests, Trees and Vegetation Policies 1 & 3). The subject site currently has two single family detached structures onsite with mostly residentially landscaped vegetation. The application included an existing conditions sheet (Sheet 3) that includes a tree inventory and condition analysis. Four tree stands are documented in mostly fair to fair-good condition; no specimen trees were identified onsite. Staff notes the SPEX plat does not depict any Tree Conservation Areas (TCA) or other assurances to preserve any of the existing vegetation for required buffering. Plan policies encourage retention of existing vegetation for landscaping of the subject site. Analysis Staff recommends that the site layout be adjusted by moving buildings as far to the west as possible, away from Gum Springs Road, and utilize existing mature vegetation to the maximum extent practicable to screen the visual scale of the building. Staff recommends that the applicant preserve forested areas through a TCA and depict the TCA as part of a landscaping plan. Staff recommends that the applicant work with the County s Urban Forester to determine tree conservation areas (TCA). Additionally, staff recommends that new landscaping consist of indigenous trees and shrubs to promote biological diversity. Noise The Revised General Plan and 2010 CTP contain roadway noise policies, which are intended to protect noise-sensitive uses from roadway noise. The primary means to protect these uses is through proper design. Mitigation measures considered as part of the policies include adequate setbacks, earthen berms, wooden fences, and dense vegetation (Revised General Plan, Chapter 5, Highway Noise Policies, Policies 1 & 2, and 2010 CTP, Chapter 7, Noise Policies, Policies 1 & 4). All proposed land uses adjacent to any existing or proposed arterial or major collector will be designed to ensure that no residential or other noise sensitive use will have traffic impacts. Impacts occur when predicted noise levels approach or exceed the noise abatement criteria (2010 CTP, Table 7-1) or when the predicted noise levels substantially exceed existing noise levels (2010 CTP, Chapter 7, Noise Policies, Policy 1). As Pacific Boulevard is a major collector, noise impacts along this roadway should be evaluated. Plan

10 SPEX , SPEX ; Vine & Branches Church and Childcare Community Planning 1st Referral July 16, 2015 Page 9 policies call for the utilization of the latest version of the Federal Highway Administration s Highway Traffic Noise Prediction Model (FHWA-RD , as amended) to assess noise impacts (2010 CTP, Chapter 7, Noise Policies, Policy 1). The policies also include the design year noise levels, road configuration, design speed, pavement type, and topography that should go into the study to assess noise impacts (2010 CTP, Chapter 7, Noise Policies, Policy 1). Analysis Staff recommends a condition of approval requiring a noise impact study prepared according to the 2010 CTP policies for the childcare use adjacent to Gum Spring Road. Staff further recommends a condition requiring passive noise abatement measures if noise impacts are identified. RECOMMENDATION Staff finds a religious assembly with child daycare to be appropriate and consistent with County policy. However, staff cannot support the proposal because the design does not adequately address the potential impacts of the use and visual impact of the mass of the buildings. Staff has provided recommendations to address impacts of the use on adjacent properties including moving the buildings away from the road, and adding articulation and materials to bring the application in general conformance with the County s policies. Staff is available to meet with the applicant to discuss these issues. Cc: Ricky W.

The subject property is zoned TR-3LF (Transitional Residential 3; Lower Foley sub-district); under the Revised 1993 Loudoun County Zoning Ordinance (hereinafter the Ordinance ), which requires a minimum of 50% open space. Staff research indicates no previous approvals for development on the subject property. Summary of Request. Two SPEX applications are submitted to permit a church with a seating capacity greater than 300 and childcare center uses. Vines & Branches Lutheran Church, the Applicant, anticipates attendance of approximately 600 parishioners and enrollment of 250 students at the full build-out of the project. The application proposes four buildings, totaling approximately 76,000 square feet in floor area, to be constructed in two phases. Phase I will construct a 31,000 square feet building with classroom space to accommodate approximately 125 students and a multipurpose room that would be used for an indoor play area and weekend worship services. Phase II will construct three buildings that will add an additional 45,000 square feet, for a total of approximately 76,000 square feet. The Applicant anticipates the expansion to include an 18,000 square foot church sanctuary to accommodate up to 600 parishioners and a 27,000 square foot addition to the childcare center and multi-purpose room to accommodate up to 250 students. Statement of Justification. The application states the church has been holding services at Liberty Elementary School in the South Riding subdivision. Attendance is growing and the church seeks a permanent home for its congregation. Special Exception. 1. On Cover Sheet: a. Vicinity Map: the northeast corner of the Braddock Road/Gum Spring Road

14 Vine & Branches Church and Childcare Center, SPEX & August 7, 2015 Page 2 of 3 intersection depicts lots and roadways of the Whitman North application, which has not been approved. Please note that if the application is denied the vicinity map will need to be revised. The application is scheduled for the July 15 th Board Business meeting. b. Add to Note 9 to refer to the respective Endangered & Threatened Species study prepared for the subject property and its findings. Also, add reference to DCR letter dated April 9, c. Revise note 20 to remove if any ; structures exist onsite. 2. The SPEX plat, Sheet 2, depicts a Phase II building straddling over a parcel boundary line. The building is not adhering to the yard requirements of the district. Revise the plat to correct this issue. Vacating the boundary line is an option to correct this issue, which will create a new lot subject to Section Lots not subject to Section must meet Table (B) Building requirements. 3. The Ordinance does not define a multi-purpose or multi-purpose room use. The term is repeated throughout the application and must be revised to a term(s) defined in the Ordinance. If the intent is to accommodate uses accessory to a church, then a church use must established as the principal use, not a multi-purpose room. What is the function of the multi-purpose room? 4. List the floor area for the proposed uses and list the proposed floor area ratio. 5. Parking/Loading Tabulations. a. Label the chart as Parking & Loading Tabulations. b. Parking calculations include places of worship and Childcare center; however, no parking calculations are provided for the multi-purpose uses. As proposed, there is approximately 47,000 square feet of multi-purpose room that includes the Phase I childcare uses serving 125 students. After defining the multipurpose term, revise chart to accurately list proposed uses and minimum required number of parking spaces per Section c. Provide the number of required and proposed pickup & drop-off spaces in accordance with Section 5-609(B)(2)(b). d. Label the number of parking spaces provided for each parking bay on SPEX plat. e. If parking is also being phased with building construction, then SPEX plat must demonstrate adequate parking for each phase. Depict phasing of parking, if any. 6. Depict the location of required outdoor play area in compliance with Section Section 5-609(B)(2) requires parking areas for child care centers to enhance the safety of children as they arrive and leave the facility and provide safe and clearly designated access to enter or exit the center. Provide Pedestrian Access that demonstrates compliance to this section. 8. The Plat depicts a location for a potential dumpster. Add note to require screening of dumpster in compliance with Section should a dumpster be provided onsite. 9. Landscaping and Buffering - The buffer depicted along Gum Spring Road frontage is

15 Vine & Branches Church and Childcare Center, SPEX & August 7, 2015 Page 3 of 3 listed incorrectly. No landscaping plan has been provided to demonstrate compliance with the Zoning Ordinance. The Zoning Ordinance requires the following: a. Section (B)(1) requires one (1) canopy tree per ten (10) parking spaces. Parking spaces shall be within 80 feet of landscaped open space. b. Section (B)(4) requires a canopy tree at the end of every row of parking. c. Section (C) requires peripheral parking lot landscaping. d. In accord with Section , Landscaping, buffering, and screening shall be used to screen outdoor storage, areas for collection of refuse, loading areas and parking. e. Section (E) requires minimum Type 3 Buffers along existing or planned four-lane divided roadways. Revise plat to depict a Type 3 buffer along the subject site s frontage of Gum Spring Road (Route 659). Issues for consideration. 10. Factor 4 The SOJ states that environmental or natural features will be preserved to the maximum extent possible. However, the Applicant submitted studies to verify that wildlife habitat, vegetation, topographic, scenic, archaeological or historic features, and forest resources do not exist on the subject property. Revise the SOJ with a statement to this affect and address whether wetlands, water quality and agricultural lands are adequately protected or mitigated.

ILLUSTRATIVE PLAN

22 County of Loudoun Department of Transportation and Capital Infrastructure MEMORANDUM DATE: November 6, 2015 TO: FROM: Kate McConnell, AICP, Project Manager Department of Planning and Zoning Marc Dreyfuss, Transportation Planner DTCI, Transportation Planning & Operations Division SUBJECT: SPEX Vine and Branches Church SPEX Vine and Branches Child Care Second Referral Background This referral updates the status of comments noted in the first Department of Transportation and Capital Infrastructure (DTCI) referral on these Special Exception (SPEX) applications dated July 31, These applications propose to allow development of an approximately 76,000 SF church with a seating capacity of 600 and child care center with 250 students. The 9.28-acre subject property is located on the west side of Gum Spring Road (VA Route 659) north of Lennox Hale Drive (VA Route 3306) and is zoned TR-3LF (Transitional Residential 3 - Lower Foley) under the Revised 1993 Zoning Ordinance (Zoning Ordinance). The subject property is currently undeveloped and has site access via two residential driveways, which are not proposed to be retained. Access is proposed via a full-movement access point from Lennox Hale Drive and an either right-in / right-out, right-in / left-in / right-out, or full-movement access point from Gum Spring Road. Department of Transportation and Capital Infrastructure (DTCI) review of these applications is based on materials received from the Department of Planning and Zoning on October 7, 2015, including: (1) an Information Sheet, dated October 7, 2015; (2) a Response Letter to DTCI First Referral Comments prepared by Cooley, LLP, dated October 1, 2015; (3) a Response Letter to VDOT Comments prepared by Gorove / Slade Associates, dated September 30, 2015; (4) a Statement of Justification prepared by the Applicant, dated September 22, 2015; (5) a Traffic Impact Study (TIS) prepared by Gorove / Slade Associates, dated May 15, 2015 and revised through September 30, 2015; and (6) a Special Exception Plat (plan set) prepared by J2 Engineers, dated June 2015, revised through September 28, Attachment 1e

23 Review of Applicant s Traffic Impact Study (TIS) SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI Second Referral Comments November 6, 2015 Page 2 The Applicant submitted a revised Traffic Impact Study (TIS) with the most recent submission, which is dated May 15, 2015 and revised through September 30, 2015 as part of the Special Exception applications for the development of proposed church and child care center. The revised TIS included intersection spacing analysis along Gum Spring Road and analysis of a modified access concept at the site driveway from Gum Spring Road (Alternative 2b). The revised TIS did not include any revisions to the previous trip generation forecasts or to access scenarios (Alternative 1 and Alternative 2) presented in the previous submission. Intersection Spacing Analysis along Gum Spring Road The revised TIS included an analysis of spacing along Gum Spring Road between the site driveway and the existing intersections immediately to the north and south of the site. This diagram is provided as Attachment 1 (Figure 11). A supplemental diagram with the Whitman Property South application is provided as Attachment 2 (Figure 54). These diagrams show the same spacing between the intersections, with 690 feet along Gum Spring Road between the site driveway and Braddock Road to the north, and 615 feet along Gum Spring Road between the site driveway and Lennox Hale Drive to the south. The TIS notes that both of these entrances meet minimum VDOT spacing requirements for an unsignalized intersection along a major collector road with a speed limit of 35 MPH. Alternative Access Proposal for the Gum Spring Road / Site Driveway Intersection This revised TIS included a new access alternative at the intersection of Gum Spring Road / Site Driveway. In the initial TIS submission, Alternative 1 proposed a right-in / right-out (RI/RO) intersection with no median break, while Alternative 2 proposed a full-movement intersection. In the first submission, the Applicant proposed that Alternative 1 would be employed if a median break is not established along Gum Spring Road opposite the site driveway by other parties, while Alternative 2 would occur if such a median break opposite the proposed site driveway on Gum Spring Road is constructed. New to this submission, the Applicant included a modification option for the scenario associated with Alternative 2. Alternative 2b would utilize the median break to provide for left-turning movements from northbound Gum Spring Road into the subject property, but would prevent all movements except right turns onto southbound Gum Spring Road. As such, this would be a right-in / left-in / left-out (RI/LI/RO) intersection. Alternative 1 is still proposed for the site if no median break is constructed opposite the site driveway. Phase 1 (2017) Trip Distribution and Assignment from the Proposed Development with Alternative 2b Assuming lane configurations and traffic controls in 2017 as shown on Attachment 3 (Figure 28) and applying trip distributions as shown on Attachment 4 (Figure 12), site-generated primarily trip assignments with Alternative 2b were analyzed and shown on Attachment 5 (Figure 17). Site pass-by trips for this alternative are shown on Attachment 6 (Figure 18) and site diverted link trips are shown on Attachment 7 (Figure 19).

24 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI Second Referral Comments November 6, 2015 Page 3 Phase 1 (2017) Forecasted Traffic Volumes and Levels of Service with Alternative 2b In order to determine the Phase 1 (2017) traffic volumes for Alternative 2b, the TIS utilized Synchro 8 based on the Highway Capacity Manual (HCM 2000) to determine levels of service (LOS) for the existing and anticipated roadway network, lane uses, traffic control devices, and traffic volumes at the four analyzed study area intersections. Phase 1 (2017) traffic forecasts are shown on Attachment 8 (Figure 20). The Applicant conducted an LOS analysis based on these traffic forecasts, provided as Attachment 9 (Figure 27). The results of the LOS analysis indicated that with the proposed improvements, all approaches and movements at intersections in the study area would operate at acceptable levels of service (LOS D or better). Total Future (2020) Trip Distribution and Assignment from the Proposed Development with Alternative 2b Assuming lane configurations and traffic controls for 2020 with Alternative 2b as shown on Attachment 10 (Figure 51) and applying trip distributions as shown on Attachment 4 (Figure 12), site-generated primary trips are shown on Attachment 11 (Figure 40). Site pass-by trips are shown on Attachment 12 (Figure 41) and site diverted link trips are shown on Attachment 13 (Figure 42). Total Future (2020) Forecasted Traffic Volumes, Levels of Service, and Recommended Mitigation Measures with Alternative 2b In order to determine the Total Future (2020) traffic volumes for Alternative 2b, the TIS utilized Synchro 8 based on the Highway Capacity Manual (HCM 2000) to determine levels of service (LOS) for the existing and anticipated roadway network, lane uses, traffic control devices, and traffic volumes at the four analyzed study area intersections. Total Future (2020) traffic forecasts are shown on Attachment 14 (Figure 43). The results of the LOS analysis for the study intersections, provided as Attachment 15 (Figure 50), indicated that all intersections would operate at acceptable levels of service (LOS D or better) under Total Future (2020) conditions with the improvements assumed in Background (2020) conditions, except the following: Intersection #1 Braddock Road / Gum Spring Road The intersection is forecast to fail during the AM Peak Hour. However, during the PM Peak Hour, all approaches and turning movements are forecast to operate at an acceptable LOS (D or better). Supplemental Analysis for Total Future (2020) with Whitman Property South Total Future (2020) Forecasted Traffic Volumes, Levels of Service, and Recommended Mitigation Measures with Alternative 2b In order to account for potential impacts of the approved (but at the time the TIS was completed, active) rezoning application for Whitman Property South (ZMAP ), the Applicant prepared a supplementary analysis to evaluate the operational functionality of the Gum Spring Road / Site Driveway 1 intersection (Intersection #2) with the addition of an eastern leg, described as Whitman South Driveway 1. This driveway would serve the property directly east of the subject property, where an active application proposes construction of a retail center and

25 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI Second Referral Comments November 6, 2015 Page 4 gas station. Additionally, this application proposes a child care center to be accessed from an eastern leg driveway at the intersection of Gum Spring Road / Lennox Hale Drive / Whitman South Driveway (Intersection #3). This analysis was provided in the Applicant s initial submission with Alternative 1 and Alternative 2. In order to determine the Total Future with Whitman Property South (2020) traffic volumes, the TIS utilized Synchro 8 based on the Highway Capacity Manual (HCM 2000) to determine levels of service (LOS) for the existing and anticipated roadway network, lane uses, traffic control devices, and traffic volumes at Intersection #2 under Alternative 2b with buildout of Whitman Property - South. For Alternative 2b, Total Future with Whitman Property South (2020) lane configurations and intersection controls are shown on Attachment 16 (Figure 57). Alternative 2b Total Future (2020) traffic forecasts are shown on Attachment 17 (Figure 55). The results of the LOS analysis at the study intersections for Alternative 2b are shown on Attachment 18 (Figure 56). The results indicated that Intersection #2 would not operate at acceptable levels of service (LOS D or better) for Alternative 2b under 2020 (Total Future with Whitman South) conditions with the improvements assumed in Background (2020) conditions, with the westbound (Whitman Property) approach failing during the AM, PM, and Sunday Peak Hours. During all other peak periods and from all other approaches, the intersection is forecast to operate at an acceptable LOS. As such, all access points between the public road network and the subject property are shown to be operating at an acceptable LOS under the RI/LI/RO scenario (Alternative 2b). Status of Transportation Comments and Recommendations Staff comments from the first DTCI referral (July 31, 2015), as well as the Applicant s responses (quoted directly from its October 1, 2015 response letter), and comment statuses are provided below. 1. Initial Staff Comment (First Referral, July 31, 2015): The following are issues with the Applicant s TIS that will affect the outcome of the study and which should be remedied and included in a revised analysis for additional review: a. On Page 43 of the Applicant s TIS, the background volumes are listed as being derived from the Traffic Impact Study for the Whitman North Rezoning. However, this study was not mentioned anywhere else in the Applicant s TIS and was not approved for use as part of the traffic scoping. The Applicant should use the approved background volume bases to determine background growth. Applicant s Response (October 1, 2015): Comment acknowledged. The typo has been corrected in the revised study. The background volumes are taken or calculated from the volumes in the Traffic Impact Study for the Whitman Property South (ZMAP ). Comment Status: Comment addressed.

26 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI Second Referral Comments November 6, 2015 Page 5 b. DTCI notes that there are no future (2017 or 2017) changes planned to the intersection of Gum Spring Road / Braddock Road at this time. As such, background and total future conditions and graphics should be evaluated without the assumed improvements at this intersection Applicant s Response (October 1, 2015): As per Loudoun County s FSM Guidelines, the study intersections need to meet the County s level of service criteria and improvements are required to be identified. The intersection of Braddock Road and Gum Spring Road operates at an unacceptable level of service in the future background conditions. Hence, mitigations are required due to existing and background traffic. With the recommended mitigations, the intersection operates at an acceptable level of service. The traffic analysis tables have been revised to show the unmitigated scenario without improvements for background and total future conditions. The proposed mitigations are consistent with those proposed in the traffic study for Whitman Property South (ZMAP ), which is currently in the process of being determined by the Board of Supervisors. Moreover, the fair share impact of the site traffic at the intersection, as shown in the Fair Share Impact section in the study, is only 4% for the 2017 conditions. Hence, the proposed development will have a minimal impact on the intersection. Comment Status: The 2010 CTP requires developments along roadways with a failing level of service to make necessary improvements to that roadway in order to satisfy 2010 CTP policy. On November 4, 2015, the Board of Supervisors approved the Whitman Property North and Whitman Property South applications, which have commitments to construct major improvements at the intersection of Braddock Road / Gum Spring Road. Comment addressed. c. The TIS assumes installation of a traffic signal at Gum Spring Road / Lennox Hale Drive / Whitman South Driveway under Background (2017) Conditions. However, this signal is only partially funded and should not be assumed in Background Conditions Applicant s Response (October 1, 2015): Please see the response to comment 1b above. The traffic analysis tables have been revised to show the unmitigated scenario without improvements for background and total future conditions. The proposed mitigations are consistent with those proposed in the traffic study for Whitman Property South (ZMAP ), which is currently in the process of being determine by the Board of Supervisors. Moreover, the fair share impact of the site traffic at the intersection, as shown in the Fair Share Impact section in the study, is only 6% for the 2017 conditions. Comment Status: The traffic signal at Lennox Hale Drive and Gum Spring Road is warranted due to traffic from the Virginia Manor community, which would include Vine and Branches Church and Child Care under 2017 conditions. On November 4, 2015, the Board of Supervisors approved the

27 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI Second Referral Comments November 6, 2015 Page 6 Whitman Property South application, which includes commitments to construct a traffic signal at this intersection. Comment addressed. d. Under the Total Future with Whitman South (2017) scenario, the TIS concludes that a traffic signal would be necessary to provide an acceptable LOS for Intersection #2. However, given the spacing of the intersection from the traffic signals at both Gum Spring Road / Braddock Road (Intersection #1) and Gum Spring Road / Lennox Hale Drive / Whitman South Driveway (Intersection #3) there does not seem to be sufficient spacing on Gum Spring Road to permit construction of a traffic signal in compliance with VDOT requirements for a major collector road. Applicant s Response (October 1, 2015): Comment acknowledged. signalized option at intersection #2 has been eliminated from the study. The Comment Status: As shown in Figure 11 (Attachment 1) and Figure 54 (Attachment 2), the proposed site driveway meets VDOT spacing requirements for an unsignalized intersection along this segment of Gum Spring Road. However, the spacing between the site driveway and Lennox Hale Drive, at 615 feet, it not sufficient to meet the VDOT standard for signal spacing along this road, which is 660 feet. DTCI notes that the Applicant has removed all references to a signal at this intersection from the traffic study. Comment addressed. 2. Initial Staff Comment (First Referral, July 31, 2015): The following are issues that will not affect the outcome of the TIS but which should be corrected in future versions of the study: a. The name of the Applicant s TIS should be Vine and Branches Church and Child Care SPEX as the special exception application is entitled. Applicant s Response (October 1, 2015): Comment acknowledged. The traffic study has been revised to address Staff s comments. Comment Status: Comment addressed. b. References to Whitman North should read Whitman Property North to reflect the correct name of the active application ZMAP Applicant s Response (October 1, 2015): Comment acknowledged. The traffic study has been revised to address Staff s comments. Comment Status: Comment addressed. c. References to Whitman South should read Whitman Property South to reflect the correct name of the active application ZMAP Applicant s Response (October 1, 2015): Comment acknowledged. The traffic study has been revised to address Staff s comments.

28 Comment Status: Comment addressed. SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI Second Referral Comments November 6, 2015 Page 7 3. Initial Staff Comment (First Referral, July 31, 2015): The following comments are related to the proposed Lennox Hale site access connection to Lennox Hale Drive: a. This segment is currently within the public ROW, dedicated to the County on May 21, 2012 (DEDI ). In order for this segment to be used for exclusive site access, it cannot remain in the public ROW. As such, this area would need to be obtained by the Applicant to be used for exclusive site access. To achieve this, a fee simple partial vacation through a boundary line adjustment (BLAD) application would need to be submitted to the County in coordination with the owners of the adjacent properties (MCPI #s and ), Dulles Farms Community Association, Inc. This BLAD application should include conveyance to the Applicant and incorporation into the ultimate single parcel for this site (Subject to the Code of Virginia through ). As a condition of approval, DTCI recommends that the Applicant commit to obtain and incorporate this area into the boundary of the site prior to approval of the first site plan. Applicant s Response (October 1, 2015): Comment acknowledged. Comment Status: Comment addressed subject to inclusion of appropriate condition language. b. DTCI notes that public roads in Loudoun County are maintained by VDOT and per VDOT regulation require at least three separate users in order to be accepted into the secondary street system for maintenance. These roads would also be required to end at a cul-de-sac or intersection with a public street to be accepted for VDOT maintenance. As such, this road segment could not provide singular site access and remain within the public ROW. Applicant s Response (October 1, 2015): Comment acknowledged. The Applicant anticipates this connection being private and not public. Comment Status: Comment addressed. c. The driveway has not been constructed. As such, it would be the Applicant s responsibility to construct this road as shown on the SPEX plat in conformance with County Policies (2010 CTP, Chapter 2, Design and Construction Standards Policy 2). This section of roadway should include a five-foot sidewalk on each side of the road to connect with the existing sidewalks along Lennox Hale Drive, per 2010 CTP policy (Chapter 4, Pedestrian and Bicycle Facilities Policies for Roadways, Policies 1, 2, 4, 8, and 15). As a condition of approval, DTCI recommends that the Applicant commit to construct this off-site roadway as shown on the SPEX plat. Applicant s Response (October 1, 2015): Comment acknowledged.

29 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI Second Referral Comments November 6, 2015 Page 8 Comment Status: Comment addressed subject to inclusion of appropriate condition language. 4. Initial Staff Comment (First Referral, July 31, 2015): It is noted that all access points to the site from the public road network must meet applicable VDOT minimum entrance standards and adequate sight distance at the entrance. DTCI recommends that a typical detail of the site entrance and/or a note stating that the entrances will meet all Loudoun County and VDOT standards be included on the SPEX plat and defers to VDOT and the Department of Building and Development for further comment. Applicant s Response (October 1, 2015): Comment acknowledged. Please see Note 5 on Sheet 2 of the SPEX plat. Comment Status: Comment addressed. 5. Initial Staff Comment (First Referral, July 31, 2015): The 2010 CTP (Chapter 2, Design and Construction Policy 4) states that interparcel access is required as a part of development proposals in the Transition Policy Area. As such, DTCI recommends that the Applicant provide an interparcel access easement between the subject property and at least one parcel to the north of the subject property to be used for access to future developments on these parcels. Applicant s Response (October 1, 2015): Comment acknowledged. As discussed with Staff during the meeting on September 1, the SPEX Plat has been revised to show the approximate location for an interparcel access on the northern property boundary. Comment Status: Comment addressed subject to inclusion on final SPEX plat. 6. Initial Staff Comment (First Referral, July 31, 2015): The 2010 CTP (Chapter 2, Design and Construction Policy 5) states that direct access from individual parcels to major collector roads is prohibited in the Transition Policy Area. However, given the traffic volumes shown in the Applicant s TIS, a right-in / right-out access driveway seems appropriate at the proposed location. Due to the access to a traffic signal at Gum Spring Road / Lennox Hale Drive, the significant traffic volumes on Gum Spring Road, and the acceptable LOS with a right-in / right-out, DTCI recommends that the Applicant remove Alternative 2 and revise the SPEX plat to show only right-in / right-out access from Gum Spring Road to the site. Applicant s Response (October 1, 2015): Alternative 2 presents the full access scenario in the traffic study. The analysis presented in the traffic study reveals that the intersection will operate at acceptable level of service as an unsignalized intersection under Alternative 2. The full access as a three-legged unsignalized intersection will also meet VDOT s spacing criteria of 440 (spacing from adjacent intersections). Alternative 2, however does not take into account the Whitman South access (forming the fourth left of the intersection). If the Whitman South rezoning is approved, a median break will be granted at that intersection. As shown in the supplemental analysis section, the intersection then will not operate at acceptable level of service as a four legged

30 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI Second Referral Comments November 6, 2015 Page 9 intersection with a median break and no signal. Taking this into account, if the Whitman South rezoning is approved, the left-out movement from the site entrance will be restricted and the entrance will operate as a Left-in Right-in Right-out. The Left-in turn lane in the northbound direction into the site entrance is a proffered turn lane by the Whitman South application. Hence, an Alternative 3 has been added in the traffic study that reflects a Left-in Right-in Right-out configuration at the site entrance. The supplemental section in the traffic study has also been updated to reflect this configuration in the traffic study. The signal option as noted earlier has been eliminated. Comment Status: DTCI notes that Alternative 1 and Alternative 2b both operate at an acceptable LOS between the public road network and the subject property, while Alternative 2 fails to achieve an acceptable LOS at all site intersections. Therefore, DTCI requests that the Applicant commit to either a right-in / right-out intersection or commit to construct a channelized intersection that will prevent left turns from the site driveway onto northbound Gum Spring Road to create a right-in / left-in / right-out (RI/LI/RO) intersection at this location if a full median break exists. In order to restrict the left-out movement, a channelization island will be needed at the site entrance. DTCI recommends that, as a condition of approval, the Applicant commit to install a channelization island to allow for right- and left-turning movements from Gum Spring Road into the site driveway, but only right-turning movements from the site driveway onto Gum Spring Road, as proposed in the Applicant s revised TIS as a RI/LI/RO intersection, and referred to herein as Alternative 2b, subject to VDOT approval. Comment addressed subject to inclusion of appropriate condition language. 7. Initial Staff Comment (First Referral, July 31, 2015): As a condition of approval, DTCI recommends that the Applicant commit to construct a 200-foot right-turn lane, as shown on the SPEX plat, along with a directional island, to ensure that the right-in / right-out access is maintained at the proposed site driveway on Gum Spring Road. Applicant s Response (October 1, 2015): Please see the response to Comment #6 above. Comment Status: Comment not addressed. DTCI reiterates its initial comment and requests that the Applicant, as a condition of approval, commit to construct a 200- foot right-turn lane, as shown on the SPEX plat, and any additional traffic control measures within the site access to limit movement from the site as related to the final intersection design at the proposed site driveway and Gum Spring Road. 8. Initial Staff Comment (First Referral, July 31, 2015): DTCI cannot discern the location of main entrances for either the church or daycare uses and therefore cannot evaluate traffic circulation patterns on the site. DTCI recommends that the Applicant provide this information on a revised SPEX plat. Applicant s Response (October 1, 2015): Comment acknowledged. The proposed entrances to the special exception uses are depicted on Sheet 3 of the revised SPEX Plat. These entrance location have been carefully designed to allow access to the buildings from parking areas and sidewalks proposed on the Property. As depicted on

31 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI Second Referral Comments November 6, 2015 Page 10 Sheet 3, the first phase of development will see a building accommodating church and child care center uses. Entrances to this building will be from the south, connected by proposed sidewalks to parking areas and Lennox Hale Drive. The parking area immediately south of these entrances will accommodate the require pick-up and drop-off area for the child care center, and parking lot aisles will provide for any necessary queuing on the Property. Each additional phase of development will have its own accesses and associated parking spaces and sidewalks. Comment Status: Comment addressed. 9. Initial Staff Comment (First Referral, July 31, 2015): DTCI notes that the Applicant has provided parking calculated for the church use and daycare use. As these uses will function at almost exclusively separate times, DTCI recommends that the Applicant consider a shared parking arrangement for the uses. DTCI defers to the Department of Planning and Zoning for further comment on parking totals and calculations. Applicant s Response (October 1, 2015): As discussed during the meeting on September 1, experience with existing churches and childcare facilities has confirmed the need for the parking spaces required for both uses. The Applicant anticipates provided a widerange of community services on the Property, which could be hosted at the same time or have an overlap of timing. Therefore, there will be periods when all proposed parking spaces are required. Furthermore, there will also be events where all attendees of the childcare facility and their families are invited to attend church services. Comment Status: Comment addressed. 10. Initial Staff Comment (First Referral, July 31, 2015): Per 2010 CTP policy (Chapter 4, Pedestrian Bicycle Facilities Policies for Roadways, Policies 1, 10, 11, 14, and 15) and 2003 Bike/Ped Plan policy (Chapter 4, Walkways & Sidewalks Policy 2a and Land Development Policies 3 and 6), bicycle and pedestrian improvements are required on baseline connecting roadways in the Transition Policy Area. DTCI notes that the Applicant has shown a 10-foot trail along the Gum Spring Road frontage of the site. As a condition of approval, DTCI recommends the Applicant construct of a 10-foot wide multiuse trail within a 14-foot wide public easement along the entire Gum Spring Road frontage of the property, meeting the existing trail on along Gum Spring Road to the south of the subject property. The Applicant should show this trail on the SPEX plat. Applicant s Response (October 1, 2015): The required trail is depicted on Sheet 2 of the SPEX Plat and is discussed in the enclosed draft development conditions. The proposed trail will connect with an existing 10 foot wide trail immediate south of the Property. Comment Status: Comment addressed subject to inclusion of appropriate condition language. 11. Initial Staff Comment (First Referral, July 31, 2015): The Applicant s Statement of Justification notes, under the Issues for Consideration section that Pedestrian connections will allow for safe and convenient navigation through the site. In order to

32 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI Second Referral Comments November 6, 2015 Page 11 ensure that these connections minimize potential conflicts between pedestrians and vehicles, and provide safe access for children and parents coming to and departing from the daycare center, DTCI recommends that the Applicant revise the SPEX plat to show these connections. Applicant s Response (October 1, 2015): Comments acknowledged. Please see Sheet 3 of the revised SPEX Plat, which has been updated to show the location of proposed on and off-site pedestrian connection and existing off-site connections. Comment Status: Comment not addressed. Appropriate on-site and off-site Applicant-proposed pedestrian facilities should be shown the SPEX plat (Sheet 2 of 4 in the most recent submission). DTCI recommends that the Applicant revise the SPEX plat to show these on-site connections, and, as a condition of approval, commit to construct a sidewalk connection between the southern site boundary and the existing pedestrian facility on the north side of Lennox Hale Drive, as shown on the SPEX plat. 12. Initial Staff Comment (First Referral, July 31, 2015): DTCI notes that the Applicant assumed improvements to the intersection of Gum Spring Road / Lennox Hale Drive / Whitman South Driveway under Background (2017) Conditions. This signal is only partially funded ($190,000). As a condition of approval, the Applicant should commit to fund the remaining costs of this signal and to have the signal operational, subject to VDOT warrants and approval, prior to occupancy. Applicant s Response (October 1, 2015): The Applicant has included a proposed draft condition requiring that the Applicant construct the traffic signal if not already constructed by another party. Comment Status: On November 4, 2015, the Board of Supervisors approve the Whitman Property South application with a condition for construction of this signal. Comment addressed. Conclusion Upon resolution of Comments 7 and 11, and inclusion of appropriate condition language as noted above in Comments 3a, 3c, 6, 7, 10, and 11, DTCI would have no objection to the approval of these applications. DTCI staff is available to meet to discuss the comments noted in this referral. ATTACHMENTS 1. Proposed Intersection Spacing Along Gum Spring Road (Figure 11) 2.

52 County of Loudoun Department of Transportation and Capital Infrastructure MEMORANDUM DATE: July 31, 2015 TO: FROM: Jacqueline Harlow, Project Manager Department of Planning and Zoning Marc Dreyfuss, Transportation Planner DTCI, Transportation Planning & Operations Division SUBJECT: SPEX Vine and Branches Church SPEX Vine and Branches Child Care First Referral Background These Special Exception (SPEX) applications propose to allow development of an approximately 76,000 SF church with a seating capacity of 600 and child care center with 250 students. The 9.28-acre subject property is located on the west side of Gum Spring Road (VA Route 659) north of Lennox Hale Drive (VA Route 3306) and is zoned TR-3LF (Transitional Residential 3 - Lower Foley) under the Revised 1993 Zoning Ordinance (Zoning Ordinance). The subject property is currently undeveloped and has site access via two residential driveways, which are not proposed to be retained. Access is proposed via a full-movement access point from Lennox Hale Drive and an either right-in / right-out or full-movement access point from Gum Spring Road. A vicinity map is provided as Attachment 1. Department of Transportation and Capital Infrastructure (DTCI) review of these applications is based on materials received from the Department of Planning and Zoning on June 19, 2015, including (1) an Information Sheet, dated June 18, 2015; (2) a Statement of Justification prepared by the Applicant, dated June 10, 2015; (3) a Traffic Impact Study (TIS) prepared by Gorove/Slade Associates, dated May 19, 2015; and (4) a Special Exception Plat (plan set) prepared by J2 Engineers, dated June 2015, revised through June 9, Compliance with the Countywide Transportation Plan The subject property lies within the Transition Policy Area (Lower Foley Subarea). The transportation network is specifically governed by the policies of the Countywide Transportation Plan (2010 CTP) and the Bicycle & Pedestrian Mobility Master Plan (2003 Bike & Ped Plan). DTCI s assessment of the transportation network is based on review of existing, planned and programmed transportation facilities, review of the Applicant s traffic study, and applicable County policies.

53 Existing, Planned and Programmed Transportation Facilities SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI First Referral Comments July 31, 2015 Page 2 The subject property is located on the west side of Gum Spring Road (VA Route 659), approximately 200 feet north of Lennox Hale Drive (VA Route 3305) and approximately 550 feet south of Braddock Road (VA Route 620). Roadways serving the site are described below. Descriptions for planned conditions of CTP roads are taken from Appendix 1 of the 2010 CTP; descriptions of planned bicycle and pedestrian facilities on CTP roads are taken from Appendix 6 of the 2010 CTP and the 2003 Bike & Ped Plan. Gum Spring Road (VA Route 659) (segment from Braddock Road to Lennox Hale Drive) is currently a 45 MPH four-lane median divided (R4M) major collector road that travels in a northsouth direction along the eastern edge of the subject property. This road is built to its planned ultimate condition in the vicinity of the site. As part of the Whitman Property South (ZMAP , SPEX , and SPEX ) application, a traffic signal is proposed to be constructed at the intersection of Gum Spring Road / Lennox Hale Drive, and a full-movement unsignalized intersection is proposed to be constructed approximately halfway between Braddock Road and Lennox Hale Drive along Gum Spring Road, opposite the Applicant s proposed Site Driveway 1. According to 2014 traffic volume estimates published by VDOT, Gum Spring Road carries approximately 16,000 vehicles per day in the vicinity of the site. Direct access to Gum Spring Road from the site is proposed via either a full-movement or right-in / right-out driveway. The 2003 Bike & Ped Plan categorizes Gum Spring Road as a Baseline Connecting Road along which bicycle and pedestrian facilities are envisioned. For four-lane roads, Appendix 6 of the 2010 CTP calls for a 10-foot wide shared use path (within the ROW or a 14-foot wide easement) on one side of the roadway, one six-foot wide sidewalk on the opposite side of the roadway, and where feasible, on-road bicycle facilities. Pedestrian and bicycle facilities are currently in place south of the site along Gum Spring Road but do not currently exist along the Gum Spring Road frontage of the subject property. Lennox Hale Drive (VA Route 3306) (segment from Gum Spring Road to Royal Hunter Drive) is currently a two-lane local secondary road that travels in an east-west direction less than 200 feet south of the southern edge of the subject property. As a local secondary road, it is not part of the CTP roadway network, but is maintained by VDOT. There are no current traffic estimates published by VDOT for Lennox Hale Drive. Direct access from Lennox Hale Drive to the site is proposed via a full-movement driveway in an existing public access easement, opposite Double Bridle Terrace. The 2003 Bike & Ped Plan does not specifically include Lennox Hale Drive, and does not consider the roadway as a Baseline Connecting Road. However, per the 2003 Bike & Ped Plan, all local secondary roads are to have sidewalks on both sides (Chapter 4, Walkways and Sidewalks Policies, Policy 2a). Sidewalks are currently in place on both sides of Royal Hunter Drive. Braddock Road (VA Route 620) (segment from Royal Hunter Drive to Riding Center Drive) is currently a 45 MPH two-lane undivided minor collector (U2) road that travels in an east-west direction approximately 550 feet to the north of the subject property. Braddock Road is planned

54 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI First Referral Comments July 31, 2015 Page 3 to ultimately be built as a four-lane median divided major collector (U4M) road and improvements have been made to the west of Royal Hunter Drive where the road is four lanes and median divided. An assessment is currently ongoing to determine the optimal way to improve Braddock Road in this segment, including improvements and alterations to its intersection with Gum Spring Road, as part of the Whitman Property North (ZMAP ) application. According to 2014 traffic volume estimates published by VDOT, Braddock Road carries approximately 5,100 vehicles per day west of Gum Spring Road and 10,000 vehicles per day east of Gum Spring Road. The 2003 Bike & Ped Plan categorizes Braddock Road as a Baseline Connecting Road along which bicycle and pedestrian facilities are envisioned. For four-lane roads, Appendix 6 of the 2010 CTP calls for a 10-foot wide shared use path (within the ROW or a 14-foot wide easement) on one side of the roadway, one six-foot wide sidewalk on the opposite side of the roadway, and where feasible, on-road bicycle facilities. A 10-foot asphalt trail currently exists along the north side of Braddock Road immediately west of Gum Spring Road. Pedestrian and bicycle facilities are not in place along the south side of Braddock Road west of Gum Spring Road or on either side of Braddock Road east of Gum Spring Road. Review of Applicant s Traffic Study (TIS) The Applicant submitted a Traffic Impact Study (TIS) dated May 19, 2015 as part of the special exception applications for the development of proposed church and daycare center. The TIS analyzed the Existing (2014/2015), Background (2017 and 2020) and Total Future (2017 and 2020) conditions at the following intersections: Gum Spring Road / Braddock Road (Intersection #1) Gum Spring Road / Site Driveway 1 (Intersection #2) (proposed) Gum Spring Road / Lennox Hale Drive / Proposed Whitman South Driveway (Intersection #3) Double Bridle Terrace / Site Driveway 2 / Lennox Hale Drive (Intersection #4) Existing (2015) lane configurations and intersection controls for roadways and intersections in the study area are shown on Attachment 2 (Figure 2). Existing (2015) Traffic Volumes and Levels of Service Traffic counts were collected during the weekday AM peak period (6:30 AM to 9:30 AM), and PM peak period (4:00 PM to 7:00 PM) on Thursday, May 15, Sunday peak period (10:00 AM to 2:00 PM) traffic counts were collected on Sunday, March 8, After collecting these counts, the AM peak hour was determined to be between 7:15 AM and 8:15 AM and the PM peak hour was determined to be between 4:15 PM and 5:15 PM. Sunday peak hour was determined to be between 12:45 PM and 1:45 PM. Existing (2015) weekday AM and PM peak hour and Sunday peak hour traffic volumes at the study intersections are shown on Attachment 3 (Figure 3). The TIS utilized Synchro 8 software based on the Highway Capacity Manual (HCM 2000) to determine Existing (2014/2015) levels of service (LOS) at the intersections noted above based

55 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI First Referral Comments July 31, 2015 Page 4 on the existing roadway network, lane uses, traffic control devices, and traffic volumes, utilizing a minimum observed peak hour factor of Results of the LOS analysis, as shown in Attachment 4 (Figure 4), indicated that all of the approaches and movements at intersections in the study area currently operate at acceptable levels of service (LOS D or better), except: Intersection #1 Gum Spring Road / Braddock Road Currently, all approaches are failing during the AM Peak Hour and the eastbound, westbound, and southbound approaches are failing during the PM Peak Hour. However, all other approaches and turning movements are operating at an acceptable LOS (D or better) during the periods analyzed. Intersection #3 Gum Spring Road / Lennox Hale Drive / Whitman South Driveway Currently, the eastbound approach is failing during the AM Peak Hour. However, all other approaches and turning movements are operating at an acceptable LOS (D or better) during all periods analyzed. Background (2017) Traffic Assumptions and LOS Analysis Background conditions analyzed in the TIS included intersection improvements to the Gum Spring Road / Braddock Road intersection, including the addition of a northbound right-turn lane from Gum Spring Road onto Braddock Road and an eastbound left-turn lane from Braddock Road onto Gum Spring Road. The reconfigured lanes due to these improvements are shown on Attachment 5 (Figure 10). The TIS utilized turning movement growth rates from the Whitman Property South (ZMAP ) TIS to estimate increased background traffic volumes. Inherent growth traffic volumes are shown on Attachment 6 (Figure 5). The TIS also considered background (2017) developments, including the anticipated initial phases of the Whitman Properties and additional planning dwelling units in Seven Hills. The locations of these developments are shown on Attachment 7 (Figure 6). The impacts of these development of the road network are shown on Attachment 8 (Figure 7). The cumulative anticipated traffic volumes from existing trips, inherent growth trips, and background developments are shown on Attachment 9 (Figure 8). The TIS utilized Synchro 8 software based on the Highway Capacity Manual (HCM 2000) to determine Background (2017) levels of service (LOS) at the intersections noted above based on the existing and planned roadway network, lane uses, traffic control devices, and traffic volumes, utilizing an assessed minimum peak hour factor of For the background future condition, results of the LOS analysis described on Page 20 (Table 3) are shown in Attachment 10 (Figure 9). These results indicated that with the proposed improvements, all approaches and movements at intersections in the study area would operate at acceptable levels of service (LOS D or better), except the following: Intersection #1 Gum Spring Road / Braddock Road Currently, all approaches are failing during the AM Peak Hour and the eastbound, westbound, and southbound approaches are failing during the PM Peak Hour. During all other peak periods and from all other approaches, the intersection is forecast to operate at an acceptable LOS. With the addition of a dedicated westbound left-turn lane at this intersection, an acceptable

56 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI First Referral Comments July 31, 2015 Page 5 LOS (D or better) is forecast for all approaches during all peak periods. However, DTCI notes that this improvement is not planned or funded at this time. Intersection #3 Gum Spring Road / Lennox Hale Drive / Whitman South Driveway Currently, the eastbound approach is failing during the AM Peak Hour. During all other peak periods and from all other approaches, the intersection is forecast to operate at an acceptable LOS. With the installation of a traffic signal at this intersection, an acceptable LOS (D or better) is forecast for all approaches during all peak periods. However, DTCI notes that this improvement is not planned at this time. Partial funding for installation of a traffic signal at this intersection has been obtained by the County through the Seven Hills rezoning (ZMAP ). Trip Generation from the Proposed Development Phase I (2017) The Applicant proposes a two-phased development with construction of a 31,000 SF building with a 300-seat church (currently allowed by-right) and 125-student day care center with an indoor play area in the first phase. The TIS considered two alternatives for the driveway from Gum Spring Road in both phases. Alternative 1 proposes a right-in / right-out entrance while Alternative 2 proposes a full-movement entrance. Trip rates from ITE s Trip Generation Manual, 9 th Edition were used to project peak hour and daily traffic volumes for the proposed Phase I and currently approved (by-right) conditions. The Applicant s TIS indicates that the proposed development would generate more daily trips as compared to the approved (by-right) development on this site. The TIS indicates that the proposed developments would generate 31 more morning peak hour trips, 25 more afternoon peak hour trips, and 566 more daily trips than the approved use. There would be no change in Sunday peak hour trips.

57 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI First Referral Comments July 31, 2015 Page 6 Phase I (2017) Trip Distribution and Assignment from the Proposed Development As shown on Attachment 11 (Figure 11), the TIS assumed a site-generated AM and PM peakhour traffic distribution of approximately: 25% of trips to and from the east along Braddock Road 25% of trips to and from the west along Braddock Road 30% of trips to and from the north along Gum Spring Road 15% of trips to and from the south along Gum Spring Road 10% of trips to and from the west along Lennox Hale Drive The TIS based these segmented distribution percentages on existing travel patterns, employment centers within the region, and the judgment of traffic engineers authoring the study. Applying trip distribution and generation metrics, site-generated trip assignments from the proposed development with Alternative 1 were calculated and are shown on Attachment 12 (Figure 12). Site-generated trip assignments from the proposed development with Alternative 2 were calculated as well and are shown on Attachment 13 (Figure 16). Phase I (2017) Trip Reductions The TIS included significant trip reductions for the child care center (68% in the AM Peak and 73% in the PM Peak) by employing pass-by and diverted link trip reductions. Pass-By Reductions Pass-by trips, which do not adversely impact the public road network, excepting entrances and exits to and from the subject property, due to the trip s preexistence along these sections of Gum Spring Road or Lennox Hale Drive, were estimated as part of this TIS for the peak hours in the peak direction. Under Alternative 1 conditions, these are shown on Attachment 14 (Figure 13). For Alternative 2 conditions, these are shown on Attachment 15 (Figure 17). Diverted Link Reductions Diverted Link trips add vehicles to the roadways immediately adjacent to the site but divert these trips from other roadways. As such, these are new trips in the vicinity of the site but not new trips to the system, due to the trip s preexistence between the origin and the ultimate destination. These trips were estimated as part of this TIS for the peak hours in the peak direction for both alternatives. Alternative 1 diverted link trips are shown on Attachment 16 (Figure 14), while Alternative 2 diverted link trips are shown on Attachment 17 (Figure 18).

58 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI First Referral Comments July 31, 2015 Page 7 Phase I (2017) Forecasted Traffic Volumes, Levels of Service, and Recommended Mitigation Measures To determine the Phase I (2017) traffic volumes, the TIS utilized Synchro 8 based on the Highway Capacity Manual (HCM 2000) to determine levels of service (LOS) for the existing and anticipated roadway network, lane uses, traffic control devices, and traffic volumes at the four analyzed study area intersections under each alternative scenario. For Alternative 1, Phase I (2017) lane configurations and intersection controls are shown on Attachment 18 (Figure 21). Alternative 1 Phase I (2017) traffic forecasts are shown on Attachment 19 (Figure 15). The results of the LOS analysis at the study intersections for Alternative 1 are shown on Attachment 20 (Figure 20). For Alternative 2, Phase I (2017) lane configurations and intersection controls are shown on Attachment 21 (Figure 23). Alternative 2 Phase I (2017) traffic forecasts are shown on Attachment 22 (Figure 19). The results of the LOS analysis at the study intersections are shown on Attachment 23 (Figure 22). The results indicated that all intersections would operate at acceptable levels of service (LOS D or better) for both Alternative 1 and Alternative 2 under 2017 (Phase I) conditions with the improvements assumed in Background (2017) conditions. Background (2020) Traffic Assumptions and LOS Analysis Background conditions for 2020 assumed the improvements to the surrounding road network completed as part of the Background (2017) analysis as well as the addition of a dedicated rightturn lane from northbound Gum Spring Road to eastbound Braddock Road and the addition of a second left-turn lane from westbound Braddock Road onto southbound Gum Spring Road. The reconfigured lanes due to these improvements are shown on Attachment 24 (Figure 28). Background conditions analyzed in the TIS included the growth rate assumed in the Whitman Property - North Rezoning (ZMAP ). However, at other points in the TIS, it is implied that the Applicant may have used rates from the Whitman Property South (ZMAP ) application. This growth rate was added to the existing (2015) traffic volumes and is shown on Attachment 25 (Figure 24). The TIS also assumed by-right development of the Whitman Properties (70 SFD units) and completion of the Seven Hills development (an additional 50 SFD units and 60 SFA units). The trips generated by these developments are shown on Attachment 26 (Figure 25). Total traffic volumes for Background (2020) are shown on Attachment 27 (Figure 26). The TIS utilized Synchro 8 software based on the Highway Capacity Manual (HCM 2000) to determine Background (2020) levels of service (LOS) at the intersections noted above based on the existing and planned roadway network, lane uses, traffic control devices, and traffic volumes, utilizing an assessed minimum peak hour factor of For the background future condition, results of the LOS analysis described on Page 47 (Table 8) are shown in Attachment 28 (Figure 27). These results indicated that with the proposed improvements, all approaches and movements at intersections in the study area would operate at acceptable levels of service (LOS D or better), except the following:

59 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI First Referral Comments July 31, 2015 Page 8 Intersection #1 Gum Spring Road / Braddock Road Under Background conditions, all approaches are failing during the AM Peak Hour. During all other peak periods and from all other approaches, the intersection is forecast to operate at an acceptable LOS. With the addition of a second dedicated westbound left-turn lane and a northbound dedicated right-turn lane at this intersection, an acceptable LOS (D or better) is forecast for all approaches during all peak periods. However, DTCI notes that these improvements are not planned or funded at this time. Trip Generation from the Proposed Development Total Future (2020) The Applicant proposes a two-phased development with construction of an additional 45,000 SF in the second phase for a total of 86,000 SF with a 600-seat church and 250-student day care center with both indoor and outdoor secured play areas. The TIS again considered two alternatives for the driveway from Gum Spring Road. Alternative 1 proposes a right-in / rightout entrance while Alternative 2 proposes a full-movement entrance. Trip rates from ITE s Trip Generation Manual, 9 th Edition were used to project peak hour and daily traffic volumes for the proposed Total Future and currently approved (by-right) conditions. The Applicant s TIS indicates that the proposed development would generate more daily trips as compared to the approved (by-right) development on this site. The TIS indicates that the proposed developments would generate 71 more morning peak hour trips, 56 more afternoon peak hour trips, 1,348 more daily trips, and 180 more Sunday peak hour trips than the approved use.

Site-generated trip assignments from the proposed development with Alternative 2 were calculated as well and are shown on Attachment 30 (Figure 33). Phase I (2017) Trip Reductions The TIS included significant trip reductions for the child care center (68% in the AM Peak and 73% in the PM Peak) by employing pass-by and diverted link trip reductions. Pass-By Reductions Pass-by trips, which do not adversely impact the public road network, excepting entrances and exits to and from the subject property, due to the trip s preexistence along these sections of Gum Spring Road or Lennox Hale Drive, were estimated as part of this TIS for the peak hours in the peak direction. Under Alternative 1 conditions, these are shown on Attachment 31 (Figure 30). For Alternative 2 conditions, these are shown on Attachment 32 (Figure 34). Diverted Link Reductions Diverted Link trips add vehicles to the roadways immediately adjacent to the site but divert these trips from other roadways. As such, these are new trips in the vicinity of the site but not new trips to the system, due to the trip s preexistence between the origin and the ultimate destination. These trips were estimated as part of this TIS for the peak hours in the peak direction for both alternatives. Alternative 1 diverted link trips are shown on Attachment 33 (Figure 31), while Alternative 2 diverted link trips are shown on Attachment 34 (Figure 35). Total Future (2020) Forecasted Traffic Volumes, Levels of Service, and Recommended Mitigation Measures To determine the Total Future (2020) traffic volumes, the TIS utilized Synchro 8 based on the Highway Capacity Manual (HCM 2000) to determine levels of service (LOS) for the existing and anticipated roadway network, lane uses, traffic control devices, and traffic volumes at the four analyzed study area intersections under each alternative scenario. For Alternative 1, Total Future (2020) lane configurations and intersection controls are shown on Attachment 35 (Figure 38). Alternative 1 Total Future (2020) traffic forecasts are shown on Attachment 36 (Figure 32). The results of the LOS analysis at the study intersections for Alternative 1 are shown on Attachment 37 (Figure 37). For Alternative 2, Total Future (2020) lane configurations and intersection controls are shown on Attachment 38 (Figure 40). Alternative 2 Total Future (2020) traffic forecasts are shown on Attachment 39 (Figure 36). The results of the LOS analysis at the study intersections are shown on Attachment 40 (Figure 39).

61 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI First Referral Comments July 31, 2015 Page 10 The results indicated that all intersections would operate at acceptable levels of service (LOS D or better) for both Alternative 1 and Alternative 2 under 2020 (Total Future) conditions with the improvements assumed in Background (2020) conditions, except the following: Intersection #1 Gum Spring Road / Braddock Road Under Total Future conditions, the eastbound, westbound, and northbound approaches are failing during the AM Peak Hour. During all other peak periods and from all other approaches, the intersection is forecast to operate at an acceptable LOS. With proposed modifications to the signal timing to adjust for anticipated traffic volumes from these approaches, an acceptable LOS (D or better) is forecast for all approaches during all peak periods. However, DTCI notes that these alternations could not be made by the Applicant and would require VDOT to change signal phase timing. Supplemental Analysis for Total Future (2020) with Whitman Property South Total Future with Whitman South (2020) Forecasted Traffic Volumes, Levels of Service, and Recommended Mitigation Measures In order to account for potential impacts of the active rezoning application for Whitman Property South (ZMAP ), the Applicant prepared a supplementary analysis to evaluate the operational functionality of the Gum Spring Road / Site Driveway 1 intersection (Intersection #2) with the addition of an eastern leg, described as Whitman South Driveway 1. This driveway would serve the property directly east of the subject property, where an active application proposes construction of a retail center and gas station. Additionally, this application proposes a child care center to be accessed from an eastern leg driveway at the intersection of Gum Spring Road / Lennox Hale Drive / Whitman South Driveway (Intersection #3). To determine the Total Future with Whitman South (2020) traffic volumes, the TIS utilized Synchro 8 based on the Highway Capacity Manual (HCM 2000) to determine levels of service (LOS) for the existing and anticipated roadway network, lane uses, traffic control devices, and traffic volumes at Intersection #2 under Alternative 2 with buildout of Whitman Property - South. For Alternative 2, Total Future with Whitman South (2020) lane configurations and intersection controls are shown on Attachment 41 (Figure 43). Alternative 2 Total Future (2020) traffic forecasts are shown on Attachment 42 (Figure 41). The results of the LOS analysis at the study intersections for Alternative 2 are shown on Attachment 43 (Figure 42). The results indicated that Intersection #2 would not operate at acceptable levels of service (LOS D or better) for Alternative 2 under 2020 (Total Future with Whitman South) conditions with the improvements assumed in Background (2020) conditions, with the eastbound and westbound approaches failing during the AM, PM, and Sunday Peak Hours. During all other peak periods and from all other approaches, the intersection is forecast to operate at an acceptable LOS. The Applicant is proposing to mitigate the failing LOS by installing a traffic signal at this intersection. With this proposed modification, an acceptable LOS (D or better) is forecast for all approaches during all peak periods.

62 Transportation Comments and Recommendations SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI First Referral Comments July 31, 2015 Page 11 DTCI staff reviewed the Applicant s submitted materials, and has the following comments: 1. The following are issues with the Applicant s TIS that will affect the outcome of the study and which should be remedied and included in a revised analysis for additional review: a. On Page 43 of the Applicant s TIS, the background volumes are listed as being derived from the Traffic Impact Study for the Whitman North Rezoning. However, this study was not mentioned anywhere else in the Applicant s TIS and was not approved for use as part of the traffic scoping. The Applicant should use the approved background volume bases to determine background growth. b. DTCI notes that there are no future (2017 or 2020) changes planned to the intersection of Gum Spring Road / Braddock Road at this time. As such, background and total future conditions and graphics should be evaluated without the assumed improvements at this intersection. c. The TIS assumes installation of a traffic signal at Gum Spring Road / Lennox Hale Drive / Whitman South Driveway under Background (2017) Conditions. However, this signal is only partially funded and should not be assumed in Background Conditions. d. Under the Total Future with Whitman South (2020) scenario, the TIS concludes that a traffic signal would be necessary to provide an acceptable LOS for Intersection #2. However, given the spacing of the intersection from the traffic signals at both Gum Spring Road / Braddock Road (Intersection #1) and Gum Spring Road / Lennox Hale Drive / Whitman South Driveway (Intersection #3) there does not seem to be sufficient spacing on Gum Spring Road to permit construction of a traffic signal in compliance with VDOT requirements for a major collector road. 2. The following are issues that will not affect the outcome of the TIS but which should be corrected in future versions of the study: a. The name of the Applicant s TIS should be Vine and Branches Church and Child Care SPEX as the special exception application is entitled. b. References to Whitman North should read Whitman Property North to reflect the correct name of the active application ZMAP c. References to Whitman South should read Whitman Property South to reflect the correct name of the active application ZMAP The following comments are related to the proposed Lennox Hale site access connection to Lennox Hale Drive: a. This segment is currently within the public ROW, dedicated to the County on May 21, 2012 (DEDI ). In order for this segment to be used for exclusive site access, it cannot remain in the public ROW. As such, this area would need to be

63 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI First Referral Comments July 31, 2015 Page 12 obtained by the Applicant to be used for exclusive site access. To achieve this, a fee simple partial vacation through a boundary line adjustment (BLAD) application would need to be submitted to the County in coordination with the owners of the adjacent properties (MCPI #s and ), Dulles Farms Community Association, Inc. This BLAD application should include conveyance to the Applicant and incorporation into the ultimate single parcel for this site (Subject to the Code of Virginia through ). As a condition of approval, DTCI recommends that the Applicant commit to obtain and incorporate this area into the boundary of the site prior to approval of the first site plan. b. DTCI notes that public roads in Loudoun County are maintained by VDOT and per VDOT regulation require at least three separate users in order to be accepted into the secondary street system for maintenance. These roads would also be required to end at a cul-de-sac or intersection with a public street to be accepted for VDOT maintenance. As such, this road segment could not provide singular site access and remain within the public ROW. c. The driveway has not been constructed. As such, it would be the Applicant s responsibility to construct this road as shown on the SPEX plat in conformance with County Policies (2010 CTP, Chapter 2, Design and Construction Standards Policy 2). This section of roadway should include a five-foot sidewalk on each side of the road to connect with the existing sidewalks along Lennox Hale Drive, per 2010 CTP policy (Chapter 4, Pedestrian and Bicycle Facilities Policies for Roadways, Policies 1, 2, 4, 8, and 15). As a condition of approval, DTCI recommends that the Applicant commit to construct this off-site roadway as shown on the SPEX plat. 4. It is noted that all access points to the site from the public road network must meet applicable VDOT minimum entrance standards and adequate sight distance at the entrance. DTCI recommends that a typical detail of the site entrance and/or a note stating that the entrances will meet all Loudoun County and VDOT standards be included on the SPEX plat and defers to VDOT and the Department of Building and Development for further comment. 5. The 2010 CTP (Chapter 2, Design and Construction Policy 4) states that interparcel access is required as a part of development proposals in the Transition Policy Area. As such, DTCI recommends that the Applicant provide an interparcel access easement between the subject property and at least one parcel to the north of the subject property to be used for access to future developments on these parcels. 6. The 2010 CTP (Chapter 2, Design and Construction Policy 5) states that direct access from individual parcels to major collector roads is prohibited in the Transition Policy Area. However, given the traffic volumes shown in the Applicant s TIS, a right-in / right-out access driveway seems appropriate at the proposed location. Due to the access to a traffic signal at Gum Spring Road / Lennox Hale Drive, the significant traffic volumes on Gum Spring Road, and the acceptable LOS with a right-in / right-out, DTCI recommends

64 SPEX Vine and Branches Church SPEX Vine and Branches Child Care DTCI First Referral Comments July 31, 2015 Page 13 that the Applicant remove Alternative 2 and revise the SPEX plat to show only right-in / right-out access from Gum Spring Road to the site. 7. As a condition of approval, DTCI recommends that the Applicant commit to construct a 200-foot right-turn lane, as shown on the SPEX plat, along with a directional island, to ensure that the right-in / right-out access is maintained at the proposed site driveway on Gum Spring Road. 8. DTCI cannot discern the location of main entrances for either the church or daycare uses and therefore cannot evaluate traffic circulation patterns on the site. DTCI recommends that the Applicant provide this information on a revised SPEX plat. 9. DTCI notes that the Applicant has provided parking calculated for the church use and daycare use. As these uses will function at almost exclusively separate times, DTCI recommends that the Applicant consider a shared parking arrangement for the uses. DTCI defers to the Department of Planning and Zoning for further comment on parking totals and calculations. 10. Per 2010 CTP policy (Chapter 4, Pedestrian Bicycle Facilities Policies for Roadways, Policies 1, 10, 11, 14, and 15) and 2003 Bike/Ped Plan policy (Chapter 4, Walkways & Sidewalks Policy 2a and Land Development Policies 3 and 6), bicycle and pedestrian improvements are required on baseline connecting roadways in the Transition Policy Area. DTCI notes that the Applicant has shown a 10-foot trail along the Gum Spring Road frontage of the site. As a condition of approval, DTCI recommends the Applicant construct of a 10-foot wide multi-use trail within a 14-foot wide public easement along the entire Gum Spring Road frontage of the property, meeting the existing trail on along Gum Spring Road to the south of the subject property. The Applicant should show this trail on the SPEX plat. 11. The Applicant s Statement of Justification notes, under the Issues for Consideration section that Pedestrian connections will allow for safe and convenient navigation through the site. In order to ensure that these connections minimize potential conflicts between pedestrians and vehicles, and provide safe access for children and parents coming to and departing from the daycare center, DTCI recommends that the Applicant revise the SPEX plat to show these connections. 12. DTCI notes that the Applicant assumed improvements to the intersection of Gum Spring Road / Lennox Hale Drive / Whitman South Driveway under Background (2017) Conditions. This signal is only partially funded ($190,000). As a condition of approval, the Applicant should commit to fund the remaining costs of this signal and to have the signal operational, subject to VDOT warrants and approval, prior to occupancy.

The Fire-Rescue GIS and Mapping coordinator offered the following information regarding estimated response times: PIN Travel Time Dulles South, Station minutes, 22 seconds Travel times are determined using ESRI GIS network analyst along the county s street centerline with distance and speed limit being the criteria. Travel time is reported in minutes and seconds. For the approximate response time two minutes is added for turnout time. Approximate response times Dulles South, Station 19 6 minutes, 22 seconds The submitted plans do not provide enough detail to evaluate adequate access and circulation of emergency vehicles. The Loudoun County Fire Code requires access within 150 feet of all sides of the building. It doesn t look like the proposed layout meets that distance requirement. The Code section may be waived by the Fire Code official if an approved automatic fire suppression sprinkler system is installed. Please provide details on type of approved automatic fire suppression sprinkler system is being proposed or revise the plat showing adequate access as required by Code. Is the area between the building and the parking lot proposed to be grass? If that is the case, some grass pavers that would allow emergency vehicles to get closer to the building may be an option.
