Marotta, Senior Planner PLANNING COMMISSION: May 18, 2010 (cancelled) June 8, 2010 AGENDA TITLE: SDP2010 -22: Hollymeade Town Center Apartments- Critical Slopes Waiver APPLICANT: Scott Collins, Collins Engineering United Land Corporation of America PROPERTY OWNER(S): Uptown Village, LLC APPLICANT'S PROPOSAL: Disturb 0.186 acres of man-made critical slopes to allow development of a 7- building, 172 -unit multi- family project in the development area. COMPREHENSIVE PLAN: The Comprehensive Plan designates this property as Urban Density in Hollymead Community Area, with a secondary landuse of Parks and Greenways. REASON FOR PLANNING COMMISSION REVIEW: Approval of modification of Section 18.4.2.3.2 to allow disturbance of critical slopes. PLANNING AND ZONING HISTORY: This parcel has a long history, as the southern half of the parcel (the portion of the site south of Towncenter Drive) is the site of the Forest Springs Mobile Home Park and many of the parcels in the immediate area are affected by numerous rezonings and special use permits associated with that use and the mobile home sales office use. The only applications that apply to this request are SP1992 -14 and ZMA 1992 -14. SP1992 -14 has conditions associated with it, but the conditions all apply to the use of a mobile home park and none of them pertain to the development of this portion of the site as a multi - family development. ZMA1992 -14 has proffers attached to it, and they will be addressed with the preliminary site plan. [Conditions attached to the preliminary site plan SDP2010 -22 (Attachment B) are incorrect.] CRITICAL SLOPES MODIFICATION: The request for a modification has been reviewed for both the Engineering and Planning aspects of the critical slopes regulations. Section 4.2.3.2 of the Zoning Ordinance restricts earth- disturbing activity on critical slopes, while Section 4.2.5(a) allows the Planning Commission to waive this restriction. The applicant has submitted a request and justification for the waiver [Attachment A], and staff has analyzed this request to address the provisions of the ordinance. 2 Critical slopes cover approximately 0.413 acres of the total project area (9.193 acres), or approximately 0.04 percent of the total project area. This request is to disturb 0.186 acres, or approximately 0.02 percent, of the 9.193 -acre project site area. The requested critical slopes to be disturbed appear to be man -made. Staff has reviewed this waiver request with consideration for the concerns that are set forth in Section 4.2 of the Zoning Ordinance, entitled "Critical Slopes." A request to allow disturbance of critical slopes must be reviewed in accord with the requirements of Section 4.2.5. This section requires a two part analysis. Section 4.2.5(a) is a review of the technical performance standards. If these technical standards are not met the disturbance of critical slopes cannot be approved by the Planning Commission. If these technical standards are met the Planning Commission may then consider the disturbance of critical slopes. The criteria for the Planning Commission's review of the disturbance of critical slopes are found in Section 4.2.5(b). Staff presents the analysis of the request to disturb critical slopes in two parts. Section 4.2.5(a) Review of the technical performance standards.: Description of critical slope area and proposed disturbance: The critical slope areas on the site appear to contain both natural and man-made slopes. The proposed disturbance is limited to man -made slopes. The critical slope disturbances are in the form of: Areas Acres Total site area 9.193 Area of critical slopes (man-made & natural) Man -made = 0.186 Natural = 0.227 % of development= 0.020% % of development= 0.024% Total critical slopes area 0.413 % of development= 0.044% Total critical slopes disturbed 0.186 % of critical slopes= 45% Below, each of the concerns of Zoning Ordinance section 18 -4.2 is addressed: 1. "rapid and/or large scale movement of soil and rock ": The areas of critical slope disturbance are presumed to be fill area from previous development in the area. Large scale movement of soil and rock is not anticipated to occur as a result of this construction. 2. "excessive stormwater run - off": Although it does not affect the critical slopes disturbance, the proposed stormwater management facility appears to conflict with a future road connection from the approved Willow Glen development to Towncenter Drive. Regardless, excessive stormwater run -off in the area of critical slopes can be limited by site design that minimizes or terraces runs of steep slopes (2:1). Proposed Building #6 has been designed as a "split- level" with a 10 -foot step differential to accommodate the existing topography as much as possible. Adjacent Building #5, although not directly located on the area of critical slopes, is only proposed with a 2 -foot step differential, creating the need for a 16 -foot vertical 2:1 fill slope behind it. It is recommended that this building be designed with a greater step differential, if possible, to shorten this 2:1 slope or that the 2:1 slope be terraced with areas of flatter grade. 3. "siltation of natural and man -made bodies of water ": A natural stream runs along the northern boundary of this parcel and needs to be adequately protected from construction activities. Grading and fill activity in close proximity to proposed Woodland Preservation areas appears to leave inadequate room for Erosion & Sediment Control measures to properly protect the site. It is unlikely that perimeter control measures can be installed without impacting the preservation areas. It is recommended that more distance be given between the back of Buildings 5 and 6 and the Preservation area, consequently reducing the amount of acreage in the Preservation area and impacting the bonus density. With enough space provided to install them, proposed E &S measures are anticipated to reduce sediment -laden runoff from leaving the site. Inspection and bonding by the County will monitor maintenance of the erosion control facilities during construction. Proper stabilization and maintenance will achieve long term stability. 4. "loss of aesthetic resource": The site plan shows the critical slopes to be within a "wooded area of hardwood trees." The disturbance of these critical slopes involves the removal of this existing vegetation. 5. "septic effluent ": The existing subdivision is served by public sewer and there are no septic drainfields within the area of this disturbance. This site does not drain into a waterway that is a public drinking water supply for Albemarle County. No portion of this site plan is located inside the 100 -year flood plain area according to FEMA Maps, dated 04 February 2005. Based on the above review, the applicant can satisfactorily address the technical criteria for the disturbance of critical slopes with the Final Grading and Erosion Control Plan, provided that sufficient area is provided for perimeter controls. Also, terracing should be considered in areas of long steep slopes. Accomplishment of these may result in the loss of some of the proposed Preservation area. Section 4.2.5(a)(3) Recommendations on the findings that must be made by the Planning Commission in order to allow disturbance of critical slopes. The commission may modify or waive any requirement of section 4.2 in a particular case upon finding that: A. 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; Strict application of the requirements of Section 4.2 would severely limit the development of this site. The critical slopes are located in the middle of the site (see Attachment Q. In order to develop and make full use of this site, disturbance of these critical slopes is necessary. Allowing disturbance of the critical slopes will facilitate the construction of a multi - family residential project within the development areas. Efficient use of the development areas furthers the Comprehensive Plan's primary landuse of Urban Density in this area. B. Alternatives proposed by the developer or subdivider would satisfy the intent and purposes of section 4.2 to at least an equivalent degree; The developer or subdivider has not proposed any alternatives that would satisfy the intent and purposes of section 4.2 to at least an equivalent degree. 4 C. Due to the property's unusual size, topography, shape, location or other unusual conditions, excluding the proprietary interest of the developer or subdivider, prohibiting the disturbance of critical slopes would effectively prohibit or unreasonably restrict the use of the property or would result in significant degradation of the property or adjacent properties; or This portion of the property is undeveloped, however it appears that some clearing was done in this area a number of years ago. The critical slopes in question may have been created as an off -site stockpile and debris area. Because of the location of the critical slopes, any development of the northern half of the project area would require disturbance of the slopes; however, prohibiting the disturbance of critical slopes would not effectively prohibit or unreasonably restrict the use of the property as the southern half of the project area would still be developable. And, the southern half of the parcel (south of Towncenter Drive) could still be used as a mobile home park. No adjacent properties would be affected by disturbance of these slopes. The county engineer has reviewed the proposed project and has deemed that an approved soil and erosion control plan would address all potential runoff and siltation issues associated with disturbance of critical slopes. Approving the waiver would not be detrimental to the orderly development of the area and would not result in significant degradation of the property or adjacent properties; conversely approval of the waiver would further County goals to promote development in development areas and further the Comprehensive Plan goal to promote urban density development in this area. D. Granting the modification or waiver would serve a public purpose of greater import than would be served by strict application of the regulations sought to be modified or waived. This property is zoned R -15 Residential within the County's Development Areas. It's Comprehensive Plan landuse recommendation is Urban Density, with a secondary landuse of Parks and Greenways. It is currently an undeveloped site, although the southern half of the parcel (below Towncenter Drive) is developed with a mobile home park. Public policy supports the proposal to further develop the site in a manner consistent with the use of Urban Density, and a multi - family development fits into that recommendation. The Comprehensive Plan also recommends projects on land with critical slopes adapt the project design to the topography and natural setting, however the subject critical slopes are not naturally occurring- they are there as a result of a soil stockpile. The proposal to allow disturbance of critical slopes for a multi - family project is consistent with the zoning in place, as well as public policy which encourages dense development in this area. Permitting disturbance of these critical slopes does not violate Comprehensive Plan recommendations to protect natural resources or terrain. As discussed above, the critical slopes proposed to be disturbed were man -made, and approximately half of the site has been disturbed by clearing. Therefore, granting the waiver, thus enabling the development of the proposed multi - family project, may be considered as supporting some County objectives. SUMMARY: Staff review has resulted in both favorable and unfavorable findings: Favorable factors: 1. The slopes to be disturbed are clearly man -made and were likely the result of an old stockpile. 2. The property is located within the development areas, and its Comprehensive Plan recommendation is to be developed as Urban Density. Allowing disturbance of critical slopes furthers County land use objectives. Unfavorable factors: 1. None identified. RECOMMENDATION: Staff opinion is that the favorable factors outweigh the unfavorable factors. Staff recommends approval of this critical slopes waiver, provided that sufficient perimeter controls are provided for with the Final Grading and Erosion Control Plan. ATTACHMENTS: A.
