Planting within this tree preservation area would be required with any removal of a tree (by the responsible party) that did not obtain prior approval by the Planning Department approval. 617SN0559-2017SEP27-BOS-RPT BUDGET & MANAGEMENT Staff Contact: Natalie Spillman (804-318-8767) spillmann@chesterfield.gov County finance staff is responsible for managing the finances of the County and making recommendations to the County Administrator regarding the allocation of available resources for the provision of services and capital facilities to serve the citizens of the County. Finance staff will advise the County Administrator if changed economic circumstances require adjustments to the County’s budget or capital improvement program. COUNTY TRANSPORTATION Staff Contact: Jim Banks (804-748-1037) banksj@chesterfield.gov The property could be developed for 123 lots. Based on that numbers of lots and applying trip generation rates for a single-family dwelling, development could generate approximately 1,271 average daily trips. Traffic generated by development of the property would be initially distributed along Beach Road. Beach Road is a major arterial with a recommended right of way width of 90 feet, as identified on the County’s Thoroughfare Plan. BeachRoad is a two-lane roadway. Sections of the road are substandard, with approximately 10-foot lane widths and no usable shoulders. VDOT minimum geometric standards recommend this road have 12-foot lane widths and 10 foot shoulders. In 2015, the traffic count on this section of Beach Road was 1,235 vehicles per day (Level of Service ‘B’). Section 19.1-231 of the County Code outlines the general requirements to meet the needsof the traffic generated by a proposed development, including acceptable levels of service. This proposed residential development would contribute to an identifiable need for transportation improvements. The applicant has offered the following: Dedication. (Proffered Condition 3.a) 45 feet of right-of-way along BeachRoad for the property frontage. Vehicular Access. (Proffered Condition 3.b) One public road to Beach Road. No direct access, except for a gated access for emergency vehiclesor one driveway, to Dry Creek Road. Road Improvements. (Proffered Condition 3.c) Left and right turn lanes along Beach Road at the approved access. Widening/improving the north side of Beach Road to a 12-foot wide travel lanewith an additional four (4) foot wide paved shoulder plus a four (4) foot wide unpaved shoulder and overlaying the full width of Beach Road for the entire property frontage. 717SN0559-2017SEP27-BOS-RPT The property is located within Traffic Shed 11, which encompasses the area of the County south of Hull Street Road, west of Winterpock Road, and north of River Road. Several roads in this traffic shed or which serve this traffic shed are substandard, with little or no shoulders, fixed objects (trees) adjacent to the edge of the pavement, and poor vertical and horizontal alignments. The traffic volume generated from this proposed residential development will contribute to an identifiable need for transportation facility improvements to these roads in excess of existing transportation facility capacity. Roads in this shed or which serve this shed need to be improved or widened to address safety and accommodate increased traffic, including the increased traffic from the proposed development. An applicant may choose to address the development’s impact on the county’s road transportation network through dedication of property, construction of road improvements, or a cash proffer. If an applicant elects to offer cash to address the impact on the county’s road transportation network, Transportation staff has calculated the average impact of a single- family dwelling unit on the transportation network to be $12,652; however, the Board of Supervisors has adopted a policy establishing that it would accept a maximum cash proffer of $9,400 per dwelling unit as addressing the traffic impacts of residential development, with all of the funds to be dedicated towards improvements to the road network. The Policy allows the county to consider mitigating circumstances about a proposed development. In this case, the residential development is not limited to a specific type. Based on the volume of traffic it generates: A single-family unit traffic impact could be addressed by $9,400 per unit. A senior housing-detached unit, which generates 46% of the traffic of single-family dwelling unit, traffic impact could be addressed by $4,324 per unit. As noted above, the applicant has proffered to widen/improve the north side of Beach Road for the property frontage, and that improvement is proffered to be completed with the initial development(Proffered Condition3.c.ii). This improvement has been estimated to be valued at $774,432. The applicant has also proffered to, at his option and in lieu of widening/improving the north side of Beach Road for the property frontage, reconstruct all of Beach Road for the entire property frontage (Proffered Condition 4.b). This improvement has been estimated to be valued at $1,548,864. It should be noted, however, that the actual cost to provide each of these improvements could be more or less than these amounts. Dependent on whether the applicant improves the north side of Beach Road or if he elects to reconstruct the entire road, the applicant has proffered to make payments of $9,400 for any residential unit beyond the total number of units that would result in an impact of $774,432 (estimated cost for improving the north side of Beach Road) or $1,548,864 (estimated cost for reconstructing Beach Road) (Proffered Condition 4). Staff supports the request.

Response Times The proposed development is located in the urban response zone for which Fire & EMS has a goal of responding to at least 90% of the calls for service in under seven (7) minutes. Fire and EMS is currently unable to meet that goal. Nearby Fire/EMS Facilities The Courthouse Fire Station, Company Number 20 Anticipated Fire & EMS Impacts/Needs Based on an average of .224 calls per dwelling, it is estimated that this development will generate 27 annual calls for Fire/EMS services. Additional Fire and EMS Comments When the property is developed, the number of hydrants, quantity of water needed for fire protection, and access requirements will be evaluated during the plans review process. 917SN0559-2017SEP27-BOS-RPT SCHOOLS Staff Contact: Atonja Allen (804-318-8740) atonja_allen@ccpsnet.net Mission High performing, high quality public schools contribute to the quality of life and economic vitality of the County. The comprehensive plan suggests a greater focus should be placed on linking schools with communities by providing greater access, flexible designs and locations that better meet the needs of the communities in which they are located. Capital Improvements The School Board FY2018 adopted Capital Improvement Plan (CIP) continues to support the 2013 voter approved school revitalization program that will replace or renovate ten schools and construct one new elementary school to add capacity in the Midlothian area of the county. The ten existing facilities that are part of the revitalization program are Providence Middle School, Monacan High School, Manchester Middle School, Beulah Elementary School, Enon Elementary School, Matoaca Elementary School, Harrowgate Elementary School, Reams Elementary School, Crestwood Elementary School, and Ettrick Elementary School. The project at Providence Middle School is currently in construction, a new Manchester Middle School is planned for construction on the existing school site,and the project at Monacan High School is complete. Additional information on the CIP can be found in the financial section of the CCPS Adopted Budget for FY2018.

LIBRARIES Staff Contact: Jennifer Stevens (804-751-4998) stevensj@chesterfield.gov Mission The public library system’s role in the county has expanded beyond its traditional function as a resource for information and materials, and now serves as a community gathering place for educational, cultural and informational services; community support during emergencies; economic development; and revitalization activities. The Public Facilities Plan, as part of the Comprehensive Plan,indicates: Nearby Libraries Clover Hill Library Public Facilities Plan The Public Facilities Plan suggests the Clover Hill Library should be expanded/replaced or a new facility shall be constructed in the general vicinity at or near current site. Land for expansion or replacement of this facility has not been acquired. PARKS AND RECREATION Staff Contact: Stuart Connock (804-751-4484) ConnockS@chesterfield.gov To date, no comments have been received. 1117SN0559-2017SEP27-BOS-RPT UTILITIES Staff Contact: Mike Larson (804-748-1338) mlarson@chesterfield.gov The proposal’s impacts on the County’s utility system are detailed in the chart below: Water and Wastewater Systems Currently Size of Existing LineConnection Required by County Code? Serviced? Water No 36”Yes Wastewater No 18”Yes Additional Information: The request site is within the Upper Swift Creek Drainage Basin and located in the mandatory water and wastewater connection areas for residential subdivision development. The applicant has proffered to use both the public water and public wastewater systems (Proffered Condition 2). There is an existing 36-inch waterline along the southern side of Beach Road with adequate capacity to serve this proposed development. Appropriately sized extensions would be the responsibility of the developer. The Ashbrook (Dry Creek) Wastewater Pumping Station transports all wastewater flows collected from the area generally bounded by Winterpock Road to the east, Beach Road to the south, Baldwin Creek Road to the west and Hull Street Road to the north. As development occurs within this area, the pumping capacity is impacted that will require an upgrade to the pumping station. The applicant has proffered a contribution of $418 per acre adjusted annually for the Marshal Swift Index not to exceed an aggregate payment of $30,000 to address this impact (Proffered Condition 3). The topography of this site will most likely require gravity wastewater lines to be extended from two different locations to properly provide service to the entire site. The western portion of the site naturally drains to the northwest. This portion of the site can be served by an existing 15-inch gravity wastewater line located approximately 4,200 linear feet away near the intersection of Otterdale Road and Harpers Mill Parkway. This line would be extended through future Harpers Mill subdivision sections. The eastern portion of this site naturally drains to the northeast. This portion of the site can be served by an existing 18-inch gravity wastewater line located approximately 6,600 linear feet away near the intersection of Harpers Mill Parkway and Thirsk Lane. The majority of this line can be extended through future Harpers Mill subdivision sections, however there are three additional properties across which the necessary wastewater easements have not yet been dedicated. Development of this portion of the site would be delayed until the easements could be acquired. The applicant has proffered to use the public water and wastewater systems and has adequately address the Ashbrook Pump Station capacity upgrade issue, therefore the Utilities Department supports this case. 1217SN0559-2017SEP27-BOS-RPT 1317SN0559-2017SEP27-BOS-RPT ENVIRONMENTAL ENGINEERING Staff Contact: Rebeccah Ward (804-748-1028) WardR@chesterfield.gov Geography The property drains via tributaries to the Swift Creek Reservoir. The entire property is located within the Upper Swift Creek Watershed. Natural Resources A Natural Resource Inventory for the western 61.6-acre portion of the property being rezoned was completed by the applicant, and reviewed and approved by the Department of Environmental Engineering-Water Quality Section. The property contains Resource Protection Area along a perennial tributary to Fuqua Branch. In addition, there are areas of interior non-tidal wetlands on the property, which cannot be impacted without a permit from the US Corps of Engineers and/or the Virginia Department of Environmental Quality. Erosion and Sediment Control Steep slopes greater than twenty (20) percent are difficult to stabilize when disturbed. The steep slopes on the subject properties border the perennial tributary to Fuqua Branch; therefore, disturbance of these slopes will result in the increased potential for sediment to impact the stream if erosion occurs. These steep slopes should remain in their natural, undisturbed state to the maximum extent practicable. Stormwater Management The development is subject to the Part IIB technical criteria of the Virginia Stormwater Management Program Regulations for water quality and water quantity. Any areas of forest/open space used for stormwater quality compliance should be outside the limits of the residential lots. 1417SN0559-2017SEP27-BOS-RPT CASE HISTORY Applicant Submittals 8/9/16 Application submitted 8/9/16, Proffered conditions submitted 5/3, 5/16, 5/22, 6/12, 7/19, 7/16, 8/2 & 8/7/17 Community Meetings 1/23/17Issues Discussed: Tree preservation area or buffer for cluster home lots when adjacent to existing homes on Dry Creek Road Density of development Location of environmental features, cemeteries, and historical buildings on the property Access to Beach Road and Harpers Mill only; prohibition to Dry Creek Road Drainage of development Impact on existing wells in area 3/30/17Issues Discussed: Conceptual layout Tree preservation area or buffer adjacent to existing homes on Dry Creek Road Access to Beach Road and Harpers Mill only; prohibition to Dry Creek Road Drainage of development Impact on existing wells in area Planning Commission 4/18/17Action – DEFERRED TO MAY 16, 2017 ON THE COMMISSION’S OWN MOTION WITH THE APPLICANTS’ CONSENT 5/16/17Action –DEFERRED TO JUNE 20, 2017 ON THE COMMISSION’S OWN MOTION WITH THE APPLICANTS’ CONSENT 6/20/17Action – DEFERRED TO AUGUST 15, 2017 ON THE COMMISSION’S OWN MOTION WITH THE APPLICANTS’ CONSENT 8/15/17Citizen Comments: No citizens spoke to this request.
