Magisterial District: Rivanna Proffers /Conditions: Yes Requested # of Dwelling Units /Lots: 129 DA - Yes RA - 5du /ac Proposal: Request to approve a preliminary Comp. Plan Designation: Neighborhood Density site plan which includes approval of open space (3 -6 du /ac) in Neighborhood 3 in accordance with Section 4.7.1 of the Zoning Ordinance and request for a waiver to disturb critical slopes in accordance with Section 4.2.3.2 of the Zoning Ordinance. This plan was reviewed by the Planning Commission on June 20, 2006. The amount of critical slopes being disturbed and the amount of trees being removed were the issues that were raised at the meeting that concerned the Commission. The applicant requested deferral of the project and has now brought back to staff a revised plan that addresses those issues. Character of Property: Borrow and Waste Use of Surrounding Properties: Adjacent to Area; New roads and stormwater facilities single family residential of Fontana and Ashcroft and Westminster Canterbury of the Blue Ridge Factors Favorable: see report Factors Unfavorable: see report STAFF CONTACT: Francis H MacCall, Senior Planner; Allan Schuck, Engineer PLANNING COMMISSION: October 10, 2006 AGENDA TITLE: SDP 2006 -0042 Pavilions at Pantops Phase 2 Townhouses Preliminary Site Plan, Open Space Appropriateness Determination and Critical Slopes Waiver PROPERTY OWNER: North Pantops Townhouses LLC APPLICANT: Southern Development BACKGROUND: Request for preliminary site plan approval to create 129 townhouses using the clustering development option on a 25.8 acre portion of a 57.88 acres site. The property, described as Tax Map 78, Parcel 12, is zoned R -6, Residential and is located in the Rivanna Magisterial District on Richmond Road [Route # US 250E] approximately 0.75 miles east of its intersection with Route 20N. The Comprehensive Plan designates this property as Neighborhood Density in Neighborhood 3 (Attachment A). Section 2.2.3 of the Zoning Ordinance states that a minimum of twenty -five (25) percent of open space is required for clustered developments. Section 4.7.1 states that the Commission shall consider the appropriateness of such areas for the intended usage in terms of such factors as location, size, shape, and topographic characteristics. The applicant is also requesting a waiver of Section 4.2.3.2, which prohibits disturbance of critical slopes. With a positive finding of the appropriateness of the open space layout and approval of the critical slopes waiver, the preliminary site plan may be approved administratively (Attachment B). At the June 20, 2006 Planning Commission meeting the applicant requested that the decision by the Commission on this plan be deferred until they were able to work on a plan that addressed the concerns of the Westminster Canterbury residents that at the meeting voiced their concerns with the plan. Staff believes that the applicant has addressed those concerns and will discuss the changes to the plan further in the report. DISCUSSION: Staff will present the discussion in three parts (1) Open Space and (2) Critical Slopes Waiver, (3) Site plan changes from the previous submittal. 1. Open Space Section 4.7 of the Zoning Ordinance (below) requires that appropriateness of open space be assessed as follows: Section 4.7.1: Does the proposed open space meet comprehensive plan objectives by providing: (1) active /passive recreation; (2) protection ofareas sensitive to development; (3) buffering between dissimilar uses; and LZ preservation off agricultural activity (1) This open space will provide both active and passive recreation. There will be areas that will have playing fields and areas that will have tot lots. There will be ponds in the largest area of open space that will provide for more passive recreation. A network of paths will be established as well, both concrete sidewalk and asphalt paths. (2) There is protection of some critical slopes within this area. These slopes will remain undisturbed within the open space areas delineated on the plan. These slopes will be protected through a maintenance agreement with the homeowners' association and further protected through the requirement of a tree conservation plan. (3) The largest area of open space is to the south and middle of the development, providing a buffer between the Westminster Canterbury development and this multifamily development. (4) This proposal does not preserve agricultural activity. This will be an urban open space system. Section 4.7.1: Is the proposed open space appropriate in terms of (1) location, (2) size, (3) shape and LZ topographic characteristics. (1) The location provides protection of critical slopes and conservation of existing trees. It also creates a buffer between this development and Westminster Canterbury, a portion of Ashcroft, and a portion of Fontana. (2) The proposal includes approximately 14.85 acres in open space, which represents 57.56% of the 25.8 acre 2 site. These 14.85 acres and the 16.43 acres of open space for the approved plan for Phase 1 totals 31.28 acres of open space or 54% of the entire 57.88 acre development. (3) The shape of the open space does not appear to pose any detriment to the development. (4) The open space will contain a variety of topographic characteristics. Some areas will be flat enough for active use and other areas will be hilly providing for a more passive use. The steepest areas are suitable for buffers and utility uses. Section 4.7.2: Will the open space be developed with any man -made features? Where deemed appropriate by the commission, open space may be used for one or more of the following uses: Agriculture, . forestry and fisheries including appropriate structures; Game preserves, wildlife sanctuaries and the like; Noncommercial recreational structures and uses; Public utilities; Wells and septic systems for emergency use only (reference 4.1.7); Stormwater detention and flood control devices. An existing stormwater management facility and public sewer lines are located in some of the open space. 4.7.3.1: In addition to provisions ofsection 4.7.1 and section 4.7.2 the commission may require inclusion in such open space of areas deemed inappropriate for or prohibited to development such as but not limited to: (1,) land in the one hundred year flood plain and significant drainage swales; (2,) land in slopes of twenty-five (25) percent or greater; (3) major public utility easements; (4) stormwater detention and flood control devices; (5) lands having permanent or seasonally high water tables; (6) areas to satisfy provisions ofsection 4.16 Recreation Regulations; (7) areas to provide reasonable buffering between dissimilar uses within such development and between such development and ad joining (1) There is no flood plain on this parcel. (2) Some of the critical slopes are shown in open space. (3) Sanitary sewer utility easements would be included in the open space. (4) One (1) stormwater detention pond is proposed (5) None of the soils located on this property are shown to support permanent or seasonally high water tables as defined in Table 16 Soil and Water Features of the United States Department of Agriculture Soil Conservation Service, Soil Survey of Albemarle County, Virginia, August, 1985. (6) The recreational areas provided satisfy the requirements of Section 4.16. (7) The open space does provide a reasonable buffer from an adjacent development. 4.7.3.3 In such case where open space is required by provisions of this ordinance not more than ei hg ty (80) percent ofsuch minimum required open space shall consist of the following: a. Land located within the one hundred year flood plain; and b. Land subject to occasional, common or frequent floodin as defined in Table 16 Soil and Water Features of the United States Department ofAgriculture Soil Conservation Service, Soil Survey ofAlbemarle County, Virginia, August, 1985; and c. Land in slopes of twenty-five (25) percent or greater; and d. Land devoted to stormwater or flood control devices except where such feature is incorporated into a permanent pond, lake or other water feature deemed by the commission to constitute a desirable open space amen] . This criterion is being met. 4.7.4: Open space in private ownership shall be protected by legal arrangements sufficient to ensure its maintenance and preservation for purposes for which it is intended. Such arrangements shall be subject to commission approval as a part of the site development plan and /or subdivision plat approval process. Open space may be dedicated to public use subject to approval and acceptance by separate resolution of the board of supervisors. Open space so dedicated shall be counted as a part of the minimum required open space. The open space shown on the plat shall be owned by the homeowners' association, which will be established by covenant during the final subdivision review process. Such document shall be subject to County Attorney review and approval and shall be in accordance with Section 14 -317 of the Subdivision Ordinance - Instrument evidencing maintenance of certain improvements. 3 2. Critical Slopes Waiver A modification to allow critical slopes disturbance is necessary before this proposal can be approved by the Site Review Committee. The request for a modification has been reviewed for both the Engineering and Planning aspects of the critical slopes regulations. Critical slopes disturbances that are exempt from the requirements of Section 4.2 include the installation of stormwater and sanitary sewer utilities and construction of accessways, provided that no reasonable alternative location or alignment exists. Staff has reviewed this waiver request with consideration for the five (5) concerns that are set forth in Section 4.2 of the Zoning Ordinance entitled "Critical Slopes." Staff has reviewed this request as required by Sections 4.2 and 4.2.5 of the ordinance. This review is divided into two parts, a review for the engineering impacts and a review of impact on aesthetic resources. Review of the request by Current Development Engineering staff: Description of critical slope area and proposed disturbance: This is a large mountainside and stream valley running downhill from Westminster Canterbury and Route 250. Some of the site has already been graded under various waste area grading permits and road plans. Areas of original ground and trees remain on the steeper slopes leading up to Westminster Canterbury. Areas Acres Total site 25.8 Critical (18 acres) This is visually estimated at 70% of the site, based on the out -dated aerial topography slopes 07 June 06 supplied with the site plan. Much of the site has already been disturbed. Rev. 1: The applicant states this information on Sheet 3 of 14, rev. date 18 September 2006 (7.96 ac) Much of the site has been disturbed. 28 Sept 06 Critical All 100% of critical slopes. It is anticipated that the entire site will be cleared and graded. slopes disturbed Rev. 1: The applicant's new plan indicates 4.97 acres of critical slopes disturbance. This (4.97 ac.) disturbance is 62.4 % of the total critical slopes on this property. . 0 Verona Drive Looking NE towards Fontana.

Stormwater facility to the left Exemptions to critical slopes waivers for driveways, roads and utilities without reasonable alternative locations: Any exempt disturbances have already taken place, as shown in the photos above. Compliance with Zoning Ordinance 18 -4.2: "movement of soil and rock" Proper slope and wall construction, control of drainage, and vegetative stabilization will prevent any movement of soil. "excessive stormwater runoff' Stormwater runoff will be increased in this area, but is collected in the system of ponds built with the project. "siltation" Inspection and bonding by the County will ensure siltation control during construction. Proper stabilization and maintenance will ensure long term stability. Most of the silt control measures are already in place for on -going construction activities. "loss of aesthetic resource" See Review of the request by Current Development Planning and Zoning staff. "septic effluent" The site is serviced by public sewer. Based on the review above, there are no engineering concerns which prohibit the disturbance of the critical slopes as shown. Review of the request by Current Development Planning and Zoning staff: The Planning analysis of this request addresses the concern for the possible loss of aesthetic resources. From an aesthetic perspective, staff can support this waiver request. Some of the proposed development is located in an "Important Wooded Area" as defined in the Open Space Plan. The Open Space Plan states that the "objectives and 5 strategies are not intended to reduce density or development rights beyond that allowed under current regulations without compensation." Regarding "Important Wooded Areas ", the plan states "In these areas, trees should be preserved or established as development occurs." Section 32.7.9 of the Zoning Ordinance requires that there must be replanting sufficient that 20% of the tree canopy will be restored within a ten year time span. The landscape plan will show the canopy requirement of at least 20 %. The Open Space Plan also states that the short term strategy is to preserve or establish trees as development occurs in "Wooded areas visible from Monticello, especially in Neighborhoods Three and Four, which protect Monticello's viewshed." The impact on the viewshed has been an issue in recent years with the intense development in the Pantops area. The establishment of trees up to and beyond the required canopy requirements has been the accepted practice to mitigate the impact on the Monticello viewshed. The Monticello Foundation has now had a chance to review the plan and discuss with the applicant the measures needed to mitigate the impact on the Monticello viewshed. (Attachment D) Summary of review of modification of Section 4.2: Section 4.2.5 establishes the review process and criteria for granting a waiver of Section 4.2.3. The preceding comments by staff address the provisions of Section 4.2.5a. Staff has included the provisions of Section 4.2.5b here, along with staff comment on the various provisions. The commission may modify or waive any requirement of section 4.2 in a particular case upon finding that: 1. Strict application of the requirements of section 4.2 would not forward the purposes of this chapter or otherwise serve the public health, safety or welfare, or that alternatives proposed by the developer would satisfy the purposes of section 4.2 to at least an equivalent degree; or A large amount of critical slopes are being disturbed and being done so within an Important Wooded Area and the Monticello viewshed. However, the development proposal includes appropriate replanting of the site to provide a minimum 20% canopy, which should mitigate to a certain extent the impacts on the wooded area and the Monticello viewshed. Therefore, staff finds that a strict application of the requirements set forth in Section 4.2 would not forward the purposes of this chapter or otherwise serve the public health, safety or welfare. 2. Due to its unusual size, topography, shape of the property, location of the property or other unusual conditions, excluding the proprietary interest of the developer, the requirements of section 4.2 would effectively prohibit or unreasonably restrict the use of the property or would result in significant degradation of the site or adjacentproper ties. Such modification or waiver shall not be detrimental to the public health, safety or welfare, to the orderly development of the area, or to adjacent properties, or be contrary to sound engineering practices; or Approval of this request would accommodate the by -right redevelopment/ infill of property within the development areas of the Comprehensive Plan with minimal impacts. 3. Granting such modification or waiver would serve a public purpose of greater import than would be served by strict application of section 4.2 Staff has identified no evidence that the act of granting the proposed waiver would serve any greater public purpose than would be served by a strict application of Section 4.2. Generally staff finds that this request is consistent with the criteria of Section 4.2.5a for granting a waiver and is therefore able to recommend approval to the Commission of a waiver of Section 4.2.3. 0 3. Site Plan Changes from the Previous Submittal The revised site plan that the applicant has provided has changed considerably from the previous proposal. The main changes are as follows: 1. Two areas of tree preservation have been provided. 2. The amount of open space has increased from 8.83 acres to 14.85 acres, a 68% increase. 3. The number of dwelling units has changed from 137 to 129, a 5.8 % reduction. 4. The travel ways have been rearranged. This allowed the two areas of tree preservation. 5. The amount of critical slopes disturbances has been reduced. Staff believes that these changes have appropriately addressed the concerns raised at the June 20, 2006 Planning Commission meeting. RECOMMENDED ACTION: Staff has reviewed this request for compliance with the provisions of the Zoning Ordinance and recommends the following: The Commission find that the open space is appropriate for the proposed development and the Commission approves the waiver of Section 4.2.3.2 of the Zoning Ordinance, to allow the disturbance of critical slopes. With a positive finding of the appropriateness of the open space and approval of the critical slopes waiver request, the preliminary site plan may be approved with conditions. CONDITIONS OF APPROVAL: 1. [ 13.4.1 ] Prior to final approval a Conservation Plan as specified in section 32.7.9, must be approved by the Zoning & Current Development Division of the Department of Community Development with a copy of the original Conservation Plan and all subsequent revisions to be submitted to the Zoning & Current Development Division. 2. [14 -317, 18 -4.7] Prior to final approval the applicant must submit covenants or other such instrument, which evidences the establishment of an owners' association and provides for ownership and maintenance of proposed open space. Such document shall be subject to County Attorney review and approval and shall be in accordance with Section 14 -317 of the Subdivision Ordinance - Instrument evidencing maintenance of certain improvements. 3.
