PROJECT NARRATIVE STEEP SLOPES The owner is proposing to construct approximately 113,650-sf of light industrial. space ( 3 separate buildings) and associated infrastructure on the 14.06 -acre property located in the Development Area of Albemarle County. Approximately half of the property is located to the north of Moores Creek Lane and the other half is on the south: side. The owner is proposing to develop the north side of the property, which consists of approximately 4.5 acres and is located outside of the 100 -year floodplain. This area is characterized by steep slopes, with a portion of froth managed and preserved slopes as shown on the site plan. ACCESS Due to the steep grades across the site that precludes the connection of onsite roadways, there are three separate accesses to the property. The first two access points to the property are proposed CG -11 entrances, one off of Broadway Street and the other off of Moores Creep Lane. Intersection sight distance and 263 feet of corner clearance (€ninimum 225 feet) from the Franklin Street intersection are provided as required by VDOT. Note that Franklin Street is owned and maintained by the City of Charlottesville and Moores Creek lane is a private street. The third access is via the existing travelway on the adjacent industrial site to the northeast. There is an existing access easement through which the developer will extend the access road to a portion of the property that is located within preserved slopes on three sides. STORMWATER MANAGEMENT The site drains to the southwest towards. Moores Creek, which is located on the southern edge of the property. Currently, there is an existing 24" culvert that collects site runoff via a ditch on the northern side of Moores Creek Lane and outfalls to the south towards Moores Creek. The owner is proposing to capture the flow at structure 2, thereby, reducing the overall flow to the existing 24" culvert. The new storm system is sized with 10 -year storm capacity ;and directs runoff to a proposed stormwater management pond that satisfies the lyr energy balance condition. The site discharges at a location where the contributing drainage area (30.9 square miles) is 1,407 tunes greater than the 14.06 acre drainage area and the discharge is non-erosive with the proposed pond. The owner is proposing to purchase phosphorus bank: credits (3.05 Ila/yr) to fulfill the water quality requirements. PARKING/LOADING The site is comprised of thirteen separate buildings. Parking calculations have been provided to indicate compliance with the parking/loading ordinance for a light industrial/warehouse use which is based on number of employees on the largest shift and area of space open for customer use. As building permits are submitted for individual buildings, parking will need to comply with the calculations on the site plan to ensure adequate parking is provided. Managed Slopes The developer is proposing to disturb portions of Managed Slopes on the property. For these locations, the disturbance is by -right and the developer will adhere to the design requirements of 30.7.5 There are four locations where the owner is proposing to disturb preserved slopes. in each location, the disturbance is by -right per 30.7.4.b.1.(c), which allows the disturbance of preserved slopes for the installation of public facilities. All three crossings will be completed as close as practicable to perpendicular to the slope, and will be cleared to the minimum extent possibleto install the utility as directed.by the ordinance. Location 1: Northeast corner of the site at the offsite access easement This portion of the site is bordered on all downhill sides by preserved slopes. Water and sewer are located several hundred feet away in Broadway Street. The proposed building is to be located approximately 15 feet vertically below the end of the existing travelway, which makes connection to public storm, sanitary and water impractical in that direction. in order to connectto public facilities, the developer is proposing to clear a minimal portion of preserved slopes to install the storm drainage outfall and a sanitary sewer/watermain connection. Location 2: At the site drainage outfall location across Moores Creek Lane The developer is proposing to install a public storm drain across the preserved slopes in accordance with the natural low point of the site. The other option is impractical since it involves forcing drainage toward the Moores Creek Lane/Franklin Street intersection, where installation of a suitable outfall channel would require the disturbance of more preserved slopes than the current plan. This direction involves construction of additional storm sewer that forces the water to un -naturally change direction via a 180 -degree turn to ultimately direct runoff to the same point as proposed. With the proposed reduction in drainage area to the Moores Creek Lane roadside ditch, the proposed option is more desirable. Location 3: Below building 12 The developer is proposing to install a public storm drain across the preserved slopes in order to convey the public water from TMP 77-40N and TMP 77-40M. Location 4: Across from building 5 The owner is proposing to construct a sanitary connection that does not travel through a retaining wall and is using this area to eventually connect to existing RWSA Manhole MCI -Mil -03, SWI Cover Sheet SW2 Notes & Details SW3 Existing Conditions / Demo Plan SW4 Phase I Erosion & Sediment Control Plan SW5 Phase 11 Erosion & Sediment Control Plan SW6 Storm Sewer Profiles SW7 Storm Sewer Profiles and Calculations SW8 Storm Sewer Drainage Areas SW9 Stormwater Management Plan SW 10 Details SP 11 Details 1.
