PLANNING COMMISSION RECOMMENDATION RECOMMEND APPROVAL SUBJECT TO THE CONDITIONS ON PAGES 2 AND 3, AND ACCEPTANCE OF PROFFERED CONDITIONS ON PAGES 3 THROUGH 12. STAFF RECOMMENDATION Recommend approval for the following reasons: me The proposed Zoning, land uses, and Master Plan conform to the Central Planning Area Land Use and Transportation Plan, as recom- mended by the Planning Commission. Be Through the Conditional Use Planned Development process, quality development and land use compatibility can further be assured. The proffered conditions, as well as statements contained in the Textual Statement, will ensure that the project develops in a qual- ity manner, compatible with the existing zoning as well as future development in the Route 10 corridor. The applicant has prepared a traffic impact study that adequately assesses the traffic impact of this development. The application and Master Plan have been revised to incorporate additional land area into the office tract, which lies to the east of the proposed major north/south road, which aligns with Lewis Road. The Central Plannin~ Area Land Use and Transportation Plan, as recommended by the Planning Commission, proposes office use for a depth of approximately 500 feet off Route 10. The resulting land area designated for office use would allow the ability to share access to Route 10 and through the interior of the development, and further ensure land use compatibility. (NOTE: THE CONDITIONS NOTED WITH "STAFF/CPC" WERE AGREED UPON BY BOTH STAFF AND THE COMMISSION. CONDITIONS WITH ONLY A "STAFF" ARE RECOMMENDED SOLELY BY STAFF. CONDITIONS WITH ONLY A "CPC" ARE ADDITIONAL CONDITIONS RECOMMENDED BY THE PLANNING COMMISSION.) CONDITIONS (STAFF/CPC) 1. The following conditions notwithstanding, the plan pre- pared by Higgins Associates, Inc., dated April i1, 1986, and the Textual Statement, dated August 6, 1986, shall be considered the Master Plan.

(EE) Specific roadway improvements set forth in the transporta- tion proffers are required by the time of full site devel- opment, and are to be constructed in accordance with the phasing plan approved by the Transportation Department. The developer shall provide the Transportation Department with additional traffic studies upon completion of each phase, if requested. Roadway improvements shall be in- creased or decreased by the developer, as required by the Transportation Department, if these studies demonstrate that traffic generation and distributions (solely by this development) are materially different, as determined by the Transportation Department, from projections set forth in the traffic study prepared by Wilbur Smith and Associ- ates, Inc. for this project. If satisfactory improvements cannot be provided, the Planning Commission may reduce the permissible densities to the extent that acceptable levels of service are provided, as determined by the Transporta- tion Department. (T) The southernmost access road shall be constructed to a three (3) lane typical section at its intersection with Route 10. (T) (STAFF/CPC) 9. Ail public roads shall be bonded to meet State standards for acceptance into the State system at the time of right of way dedication to the County. (P) (Note: This condition supersedes Section III. Multi- family (Tracts F-1 and F-2), paragraph B. Development Conditions, sub-paragraph 18. Proffered Conditions A. Traffic Proffered Conditions (STAFF/CPC) 1. In connection with Schematic Plan Review for portions of the Property abutting Route 10, additional right of way shall be dedicated to Chesterfield County so that the distance between the property line abutting the right of way of Route 10 and the existing centerline of the right of way for Route 10 is approximately one hundred (100) feet. (STAFF/CPC) 2. At the time of the first Schematic Plan Review for devel- opment on the Property, an access plan for Route 10, the Parkway, and the northernmost access road serving the Property shall be submitted to, and approved by, the Planning Commission. Thereafter, modifications to the aforesaid access plan shall be subject to approval by the Planning Commission. 3 86S097/BSAUG6/SEPT10GG (STAFF/CPC) 0 To the extent such improvements are inadequate or not in place at the time of development, the following roadway improvements will be constructed in connection with the development of portions of the Property directly served by such roadway improvements, as specified: (a) The location of the intersection of the northernmost access road to the Property and Route 10 shall center approximately on the point of extension of the exist- ing northern boundary of Parcel 114-5 (1)- 1 and the western boundary of the Property, as shown on the Chesterfield County Tax Maps. At the intersection of the northernmost access road to the Property and Route 10, a median break will be provided with two exclusive left-turn lanes for southbound traffic entering the Property and an exclusive left-turn lane for northbound Route 10 traffic. A left-turn lane, a through lane, and a right-turn lane will be provided for westbound traffic on the northernmost access road approaching Route 10. Further, a deceleration lane will be provided for traffic traveling north on Route 10 to expedite turns onto the northernmost access road to the Property. (b) At the intersection of the proposed Parkway, Lewis Road and Route 10, a median break will be provided with an exclusive left-turn lane for traffic north- bound turning left from Route 10 onto Lewis Road, and for a southbound traffic turning left from Route 10 to the proposed Parkway. Further, a deceleration lane will be provided for traffic traveling north on Route 10 to expedite right turns onto the Parkway. At its intersection with Route 10, the Parkway will have an exclusive left-turn lame, through lane, and right-turn lane (a five-lane typical section). The Parkway will then taper to a four lane, divided road at its intersection with the northernmost access road. It shall then taper to a two-lane typical section and stub into the northern boundary of Tract A. The developer shall be required to build only that portion of the Parkway necessary to serve devel- opment on the Property. (e) At the intersection with Edenshire Road, the southernmost access road to the Property and Route 10, a median break will be provided with exclusive left-turn lanes to serve traffic turning left from Route 10 to the Property or Edenshire Road. At its intersection with Route i0, the southernmost access road will consist of one entering lane and one exit- ing lane. Further, a deceleration lane will be provided for traffic traveling north on Route 10 to expedite right turns into the Property. .' ~ 4 ~6S097/BSAUG6/SEPTlOGG (STAFF/CPC) (d) The developer will provide traffic signalization (as warranted) at the following intersections: (i) the intersection of the proposed Parkway, Lewis Road and Route 10; and (ii) the intersection of the northernmost access road to the Property and Route 10. (e) The access road to Tract H-i, north of the Parkway, will provide a right turn in and right turn out for traffic generated by development on Tract H-1. (f> In connection with development of the Property, an additional through lane for northbound Route 10 and curb and gutter, adjacent thereto, will be installed by the developer, phased as approved by the Planning Commission, to correspond with development of por- tions of the Property adjoining the additional through lane. (g) In connection with the development of Tract J-2, the developer will provide for the dedication of a stub road, to provide eventual vehicular access for Prop- erty lying south of Tract J-2, to the southernmost access road serving the Property. (h) Any deviation from the design criteria set forth in this Condition 3 shall be permitted only with the approval of the Planning Commission, at the time of Schematic Plan or Plan of Development Review. Proffered Conditions Relating to Development Standards The following proffered conditions shall be applicable with respect to development of Tracts E, H-I, H-2, J-l, J-2, J-3, J-4, J-5, K-1 and K-2, except to the extent the development standards contained herein are modified by the Planning Commission at Plan of Develop- ment or Schematic Plan Review: Yard and Height Requirements.

Use of public water recommended and intended. No off- site easements will be required. Lies in Proctors Creek sewage drainage area. 30 inch trunk sewer line located approximately 9,000 feet to the east at the intersection of Chester Road and Proctors Creek. Must acquire off-site easements to extend public sewer. Use of public sewer is recommended and intended. Terrain gently sloping to moderately steep and, when cleared, has slight to severe chance for erosion. Site deemed to be fair for the proposed use. The site drains to Great Branch Creek by way of a number of tributaries conveying various amounts of off-site upstream drainage through the project. On-site creeks have been found to be, in general, poorly drained swampy areas and not well-defined. All creeks converge in the region of the project into the Corps of Engineers established floodplain of Great Branch Creek. 13 86S097/BSAUG6/SEPTIOGG Schools: Since this area has remained undeveloped with water conveyance through and from the land in its existing state traveling very slowly, there are no existing on- or off- site drainage or erosion problems. There are several anticipated drainage and/or erosion control problems, based on the proposed use. The road and lot layout on the lower portion of the project does not appear to be compatible with the exist- ing Corps of Engineers 100 year floodplain of Great Branch. Also, with reference to Exhibit E which says "...storm water will be collected from developed areas of Ironbridge through storm drainage systems and transported to a permanent water impoundment located within Ironbridge," our study of the topography would indicate that much of the residential development runoff will not be able to be conveyed to the lake under the present road, lot, and lake layout. In order to accomplish the objective of Exhibit E, the lake dam should be positioned at the most downstream point of the project as is feasible (Conditions 3, 5, and 6). Staff would support a location in the Corps of Engineers 100 year floodplain since this area does not qualify for residential development. This would also minimize, if not entirely eliminate, the subjection of homes to the potential liability of inunda- tion due to dam failure (Condition 4). The location of the lake at a point where the entire project will drain naturally to it also provides the basis for the most effec- tive possible erosion and sediment control plan for the project. Another potential problem is that the location of the northernmost portion of the residential collector road appears to be on an alignment which will necessitate the storm sewering of a large drainage area creek. Staff estimates that approximately 858 school age children will be generated by this request. ~ ' 14 '6 SOq 7/g.qAITc. a/.q~PT lnn~ Fire Service: General Plan (Central Planning Area Land Use and Transpor- tation Plan - Proposed): Transportation: Lies in Gates Elementary School attendance zone: capacity - 652, enrollment - 641; Salem Middle School zone: capacity - 1,350, enrollment - 1,144; Bird High School zone: capacity - 1,800, enrollment - 1,536. Presently, there are plans to raise the capacity of Bird High School. Overall, additional space will be required to accom- modate additional students generated by the request. Chester Fire Station, Company #1. At present, fire service capability is good. County water and fire hydrants for fire protection must be provided in compliance with nationally recognized standards. Light commercial office Low density residential (1.51-3.0 units/acre) Medium/high density residential (4.01-7.0 units/acre) High density residential (7.01 units/acre or more) Traffic generated by this proposed develop- ment will be initially distributed along Iron Bridge Road (Route 10), which had a 1985 traffic count of 18,650 vehicles per day. The Master Plan proposes four access points to Route 10; three of which align existing crossovers and the other aligns a proposed crossover. A detailed traffic impact study has been submitted. Staff has some reservations regarding the alignment of an access to the shopping center, oppo- site the Lone Star quarry access road. It may be desirable to redesign the access so that heavy truck traffic will be separated from the shopping center traffic. The Master Plan does not provide for a con- nection between the development's residen- tial road network and Chalkley Road. A connection should be provided to eliminate the need for Chalkley Road traffic to utilize Route 10 in order to get to the development. The development should also provide for future connections to the triangular-shaped property in the northwest quadrant of the Chalkley Road/Route 10 15 86S097/BSAUG6/SEPT10GG intersection to prevent road stripping of this property. Due to the straight align- ment of Deep Forest Road in the Autumn Oaks Subdivision, further extension of this road into this development may attract a high volume of "cut-through" traffic. Staff, therefore, does not recommend the con- nection be extended. (See discussion below for further analysis.) DISCUSSION The applicant is requesting amendments to a previously granted Condi- tional Use Planned Development to modify the approved Master Plan rela- tive to tract boundaries, uses within tracts, and bulk requirements in R-7, R-15, and B-1 Districts. There are eight (8) main differences between the original application and the current request. Essentially, they are as follows: The size of the lake (Tract 9 on the Original Master Plan) has been reduced from approximately 42.6 acres to approximately 19 acres. However, much of the land formerly proposed for a lake will be retained as common area. Tract 7 om the Original Master Plan, which proposed 600,000 square feet of commercial development, will be divided into two (2) separate uses on the Revised Master Plan: namely, 265,000 square feet of commercial development, and 200,000 square feet of office/service development. Tract I on the Revised Master Plan, shown as the northern portion of Tract 6 on the Original Master Plan, is proposed for development either as a hotel or housing for the elderly rather than being restricted solely for hotel use. Tract 2 on the Original Master Plan, proposed for development as a child care center, has been relocated to the area shown as Tract E on the Revised Master Plan. e Tract 10 on the Original Master Plan was proposed for the storage of recreational vehicles. It is proposed that Tract 10, shown as Tract K-1 on the Revised Master Plan and Tract K-2, as well, be authorized for retail development, and that recreational vehicle storage be located adjacent to, or within, the residential areas which they serve. The required development standards for the major roadway, extending from State Route 10 in a northeasterly direction through the property (two (2) lane or four (4) lane), should be determined at the time of development of the roadway, based on whether Chesterfield County has made a commitment at the time ~ · 16 ~6 S097/BSAUG6/SEPT10GG of the commencement of construction of such roadway, to extend or cause the extension of this roadway to Centralia Road. This amendment requests that the specific requirements in the existing Ordinance regarding fire safety be replaced with an overall comprehensive requirement that the developer comply with the Chesterfield County Building and Fire Safety Code requirements, in effect, at the time of development of the various portions of the property. Approximately 14.3 acres in the Route 10 corridor has been added to the business-office classification, in compliance with the proposed Central Plannin~ Area Land Use and Transportation Plan. The applicant's Textual Statement provides for bonding of construction in public roads in the multifamily areas, prior to occupancy of the 100th umit. Staff is concerned that the County be guaranteed that required improvements in dedicated rights of way be made prior to, or in conjunc- tion with, the dedication (Condition 9). It should be noted, however, that it may not be necessary for the developer to dedicate the right of way at a particular time. The Planning Commission, through schematic plan approval, should be able to determine when dedication of public rights of way are necessary. Based on assumed land use and densities, this proposed development could generate approximately 26,800 average daily trips; approximately the same as that which could be generated under the existing zoning. These vehi- cles will be initially distributed along Iron Bridge Road (Route 10), which had a 1985 traffic count of 18,650 vehicles per day. Existing zoning conditions required minimal improvements to Route 10. Proffers and recommended conditions will ensure that significant road improvements are provided. A traffic analysis assessing the impact of this development was submit- ted. The impact of the traffic was evaluated for a 10 year period (1996) amd a 20 year period (2006). The Master Plan depicts four points of access to Route 10. The southernmost access (residential collector) aligns an existing crossover opposite. Edenshire Road. The major access road (Parkway) aligns an existing crossover opposite Lewis Road. The main access into the shopping center area aligns an existing crossover opposite the quarry access road. The northernmost access road and a new crossover align the entrance to the small shopping center development, which is currently under construction on the south side of Route'lO. Staff has concerns relative to the two northernmost accesses. The align- ment of the shopping center access with the quarry road would cause shopping center traffic to contend with truck traffic using the quarry, and would create a potential safety problem. The main access for the shopping center should be relocated northward. The new proposed cross- over for the northernmost access road would serve this development, as well as a small shopping center development on the south side of Route 10 17 86SO97/BSAUG6/SEPTlOGG (Tax Map 114-1 (1) Parcel 11). Just south of the shopping center is a parcel of land (Tax Map 114-5 (1) Parcel 1) totalling approximately 152 acres±. The potential development on this parcel could generate more traffic than the small shopping center. The proposed crossover should, therefore, be shifted southward approximately 200± feet near the property line (between Tax Map 114-1 (1) Parcel 11 and Tax Map 114-5 (1) Parcel l) to serve the large parcel, as well as possibly the shopping center. This shift would also provide more equal spacing of crossovers along Route 10. Even though the Master Plan does not reflect this shift, the applicant's proffers address it. The applicant must receive VDH&T's approval for the installation of a new crossover. The major road improvements proffered by the applicant are as follows: New crossover at the northernmost access road with dual left- turn lanes for southbound Route 10 and a left-turn lane for northbound Route 10. A five-lane typical section for the northernmost access road and the proposed Parkway at their intersections with Route 10. Adequate left-turn lanes at both existing crossovers (Lewis Road and Edenshire Road). Additional lane of pavement and curb and gutter for the entire property frontage abutting Route 10. Exclusive right-turn lane at each location of access to Route 10. Traffic signalization, if warranted, at the proposed Park- way/Lewis Road/Route 10 intersection and northernmost access road/Route 10 intersection. In the proffers, the applicant did not include a right-turn lane (tot- ally, a three-lane typical section) for the southernmost access road at its intersection with Route 10, as indicated in the traffic analysis. Staff recommends this typical section be provided to ensure an acceptable level of service (LOS) at the intersection (Condition 8). These improve- ments should provide an adequate LOS (LOS D or better) in both the A.M. and the P.M. Peak Hours at the intersection on Route 10, except for the intersection of Lewis Road/Parkway/Route 10. During the P.M. Peak hour for the year 2006, this intersection could possibly operate at capacity (LOS E). Based on the assumptions and conservative approach in the analysis, the actual LOS at this intersection during the P.M. Peak may actually be acceptable. As development progresses on this project, Staff may require additional traffic reports and recommend additional road improvements to ensure ~ 18 . 36SO97/BSAUG6/SEPTlOGG acceptable LOS are achieved. If satisfactory road improvements cannot be provided, densities on this project may have to be reduced. (Condition 7) The applicant has proffered right of way dedication of 100 feet from the centerline along Route 10, in accordance with the Central Planning Area Land Use and Transportation Plan. A proffer condition has also been offered which provides a stub road through the proposed office parcel (J2) stubbing into the southern property line. Staff may recommend this stub be extended southeastward to intersect with Chalkley Road as future development occurs between this project and Route 10. The Master Plan depicts several other locations for stub roads. At the time of tentative subdivision review, or schematic plan review, Staff will make specific recommendations regarding recommendation for providing adequate stubs to adjacent parcels. The amended request is in conformance with the proposed Central Planning Area Land Use and Transportation Plan and meets the spirit and intent of the original zoning. The proffered conditions, as well as conditions recommended herein, will help to ensure that the project develops accord- ingly and in a manner compatible with existing and proposed area development. CASE HISTORY Planning Commission Meeting (7/15/86): The Commission resolved to defer this case for thirty (30) days due to concerns relative to drainage, traffic, and development standards in the Route 10 corridor. Staff (8/15/86): Staff has had many discussions and meetings with the applicant to attempt to resolve areas of concern. These concerns have been resolved anH the analysis revised to reflect the resolution of the concerns. Planning Commission Meeting (8/19/86): On motion of Mr. Belcher, seconded by Mr. Cowan, the Commission recom- mended approval of this request, subject to the conditions on pages 2 and 3, and the proffered conditions on pages 3 through 12. AYES: Unanimous. The Board of Supervisors on Wednesday, September 10, 1986, beginning at 7:00 p.m., will take under consideration this request. 19 86S097/BSAUG6/SEPTlOGG A EDENSHII A IRON BRIDGEA 86SO97'(AMENDED) REZ'~A TO R-15 WITH [FqB-I TO R-7 ~:]IR-7 TO B-I ~R-15 TO B-I ~AMEND C.U.PD.
