C Albemarle County, Virginia Monacan Landing WWA Project No. 217049.04 i Site Assessment Report WJAM SECTION 1 — INTRODUCTION sm 1.1 Purpose and Scope The Albemarle County Facilities and Environmental Services Department has contracted with WW Associates to perform a site assessment for the proposed Monacan Landing Park. The purpose of the site assessment is to assist the County in determining the feasibility of developing the property for use as a public park offering the following amenities: ■ Canoe/boat launch, ■ Parking Area ■ Trails/benches ■ Picnic Areas ■ Fishing Areas The Monacan Landing park property is situated on Tax Map 45, Parcel 66B and comprises approximately 20.4 acres. The property is located on the South West corner of Route 29 and Rio Mills Road. Challenges for the site include: ■ Road access. ■ Critical slopes. ■ Potential for wetlands and stream impacts. ■ The project site is located within the floodplain and the 100 foot stream buffer. The site assessment for the feasibility of developing the property for use as a public park will comprise of the following elements: ■ Provide a site layout that takes into account the site challenges. ■ The development of concept graphic that depicts the proposed site improvements. ■ Evaluation of existing available wetlands information. ■ The preparation of a site assessment report with recommendations and conclusions. ■ The generation of an estimated total project cost for the recommended improvements. Albemarle County, Virginia Monacan Landing WWA Project No. 217049.04 1-1 Site Assessment Report SECTION 2 — SITE DESCRIPTION im 2.1 Existing Site Conditions The Monacan Landing Park site is situated on the privately held property described as Tax Map 45, Parcel 66B and comprises approximately 20.4 acres. The property is located at the corner of Route 29 and Rio Mills Road along the South Fork of the Rivanna River below the d reservoir. The property is esignated as Clearing at Berkmar Drive Bridge Open Space and is located on properties designated as Rural Area per the Albemarle County Comprehensive Plan adopted June 10, 2015. The property is not within the watershed of the drinking water supply protection areas. The site is primarily forested with some clearing that was performed as part of the construction of Berkmar Drive. There is an additional clearing area adjacent to Route 29 within the utility easement for the overhead utilities that run through the site. The site lies within the designated Clearing at Route 29 floodplain as shown on FEMA Flood Plain Map number 51003CO280D with an effective date of February 4, 2005. A copy of the FEMA Flood Plain Map for the area is provided in Appendix A. The South Fork of the Rivanna River is provided with a 100 foot minimum stream buffer per the Albemarle County stream buffer ordinance. Since the property is located within the designated Rural Area the stream buffer for Moores Creek extends 100 feet from the Albemarle County, Virginia Monacan Landing WWA Project No. 217049.04 2-1 Site Assessment Report SECTION 2 — SITE DESCRIPTION im top of stream bank or the to the designated floodplain, whichever is greater as defined in section 17-600(B) of the stream buffer ordinance. Given that the project site is located within the FEMA floodplain it is therefore subject to the requirements of the Albemarle County Flood Plain Overlay District. This will require the completion of a Conditional Letter of Map Revision (CLOMR) to be submitted to and approved by FEMA for impacts to the flood plain associated with any proposed improvements. Rio Mills Road Per the 2016 Virginia Department of Transportation Daily Traffic Volume Estimates for Albemarle County, the City of Charlottesville, and the Town of Scottsville the average daily traffic (ADT) for this section of Route 29 is 51,000 vehicles per day (VDP). The average daily traffic (ADT) for Rio Mills Road is 560 vehicles per day (VDP). Albemarle County, Virginia Monacan Landing WWA Project No. 217049.04 2-2 Site Assessment Report Wad SECTION 3 — SITE ASSESSMENT Im 3.1 Site Feasibility The existing clearing located below the Berkmar Drive Bridge was analyzed as a potential location for the proposed parking area and boat launch for the Monacan Landing Park. Placement of the parking area at this location would allow for a majority of the proposed improvements to be constructed within the existing VDOT right-of-way procured as part of the extension of Berkmar Drive. Standing Water at Bridge Pier %-leanug at anuge The existing clearing at the bridge was graded during construction of the Berkmar Drive extension and is relatively level. There are some locally depressed areas around the piers with standing water. It is likely from the visual inspection that these areas are existing wetlands. There is a 24-inch storm sewer discharging runoff from the extension of Berkmar Drive that may be contributing to the standing water at the piers. It is recommended that a wetlands and stream delineation be performed to determine impacts to jurisdictional wetlands that may be located within the area of any proposed site improvements. Jurisdictional wetlands are regulated by the Army Corps of Engineers under Section 404 of the Clean Water Act. A Joint Permit Application will be required to mitigate wetlands impacts associated with the project. Albemarle County, Virginia Monacan Landing WWA Project No. 217049.04 3-1 Site Assessment Report SECTION 3 - SITE ASSESSMENT Existing Steep Slopes at Rio Mills Road There are existing steep slopes at the edge of the clearing below the Berkmar Drive Bridge. The steep slopes are located between the clearing and Rio Mills Road. The steep slopes will make access to any proposed improvements at this location difficult. A fill section would be required to accommodate the construction of an access road to a parking area in this location. As discussed in Section 2, the site is located within the FEMA defined floodplain. Per section 30.3.13 of the Albemarle County Code any fill within the floodplain area requires a special use permit. An additional site adjacent to Route 29 was evaluated as part of this assessment. There is an existing fill area located at the intersection of Rio Mills Road and Route 29. It is assumed that this area was created as a staging area for the bridge at the South Fork of the Rivanna River that constructed with the widening of Route 29 in this area. Existing Entrance at Fill Area Placement of the parking area at this location would allow for the utilization of the existing at -grade access point therefore minimizing any required grading. This would provide access to the proposed parking area as shown on the concept plan provided in this section. A 50 foot buffer strip is provided between the parking area and the South Fork of the Rivanna River. The buffer strip will provide a staging area for offloading of boats and equipment as well as assist in filtering stormwater runoff from the parking lot area. Albemarle County, Virginia Monacan Landing WWA Project No. 217049.04 3-2 Site Assessment Report Wad SECTION 3 - SITE ASSESSMENT Im The placement of the proposed improvements at this location will permit visibility of the proposed parking area from Route 29. This will provide an added sense of security for people utilizing the facilities and allow for easier monitoring of the area by law enforcement and park services. Rio Mills Road at Route 29 This portion of Route 29 lies within the Entrance Corridor for Albemarle County. Therefore the proposed improvements at the project site will require review and approval from the Architectural Review Board (ARB). Landscaping for screening of the parking areas is shown as part of the conceptual layout in accordance with ARB requirements. There are existing overhead utility lines located on this portion of the site. The utility lines are approximately 12 feet off the ground at their lowest point. The utility lines could also be raised to provide more clearance for vehicles with the addition of a mid - span pole. Figure 3-1 presents a conceptual plan for the park. A trail extension to the east side of Route 29 is depicted on the conceptual plan. The trail extension would provide a connection point to any future development that occurs in this area. Restroom facilities are not depicted as part of the conceptual plan. Facilities could be provided with portable facilities or a permanent structure. Any permanent facilities provide would need to be located outside of the flood plain in accordance with the Albemarle County Stream Buffer Ordinance. Site distance on Rio Mills Road for the entrance location depicted is marginal. Further discussion with VDOT will be required on this subject to determine adequacy. Site distance for the parking access will be addressed with final design.

SECTION 3 — SITE ASSESSMENT Im 3.2 Boat Launch A boat launch will be provided adjacent to the parking area. The existing embankments along the river are steep and difficult to navigate. Some areas of embankment within the project site are vertical due to stream bank erosion that has occurred over time. It is Typical Boat Launch recommended that the embankment at the area for the boat launch be graded to provide a gentler slope and allow easier access. The newly graded slopes should be armored with rip -rap or provided with another form of stream bank restoration to prevent future erosion. Figure 3-2 presents a graphic of a typical boat launch. Section 17-603(C) of the stream buffer ordinance states that the following with regards to acceptable uses within a designated stream buffer: "Water dependent facilities and miscellaneous. Water dependent facilities; water wells; passive recreation access, such as pedestrian trails and bicycle; historic preservation; archaeological activities; provided that all applicable Federal, State and local permits are obtained." A determination will need to be made by Albemarle County if the parking area for the proposed park meets this definition and is an acceptable use within the stream buffer. The boat launch is a "public water -oriented recreation area" and included in the definition of a "water -dependent facility" per section 18-30.3 of the Albemarle County Code.

The site was analyzed for stormwater management requirements based upon the conceptual layout. The total impervious area created with the layout is approximately 0.62 acres. The site data was entered into the DEQ Virginia Runoff Reduction Method New Development Compliance Spreadsheet. The spreadsheet indicates that the pollutant load reduction required for the improvements shown is approximately 1.12 pounds/year. A level 2 biofilter with a minimum surface area of 1,520 square feet would be required to treat the improvements shown and provide the required removal rate. In accordance with DEQ requirements soil borings would need to be performed for the construction of the biofilter to determine the percolation rate of the soils on the site and the depth to the groundwater table. A low percolation rate is anticipated for the existing soils and any biofilters constructed will need to be provided with underdrains. Conveyance channels would need to be provided to direct runoff from the areas not requiring treatment around the biofilter. Alternatively the forested area on the site could be placed into a conservation easement to satisfy the water quality requirements for the site. The impervious area created with the proposed layout is minimal in nature. An analysis of the entire parcel with the forested areas taken into account indicates that no pollutant load reduction is required for the site with this scenario. DEQ requires that any forested areas utilized for this scenario be placed into a conservation easement. This would not prevent the intended use of the property since recreational trails are allowed within the conserved areas. Based upon this analysis it is recommended that the forested areas on the site be placed into a conservation easement to satisfy the stormwater quality requirements. A summary report from the DEQ Virginia Runoff Reduction Method New Development Compliance Spreadsheet for this scenario is provided in Appendix B. Albemarle County, Virginia Monacan Landing WWA Project No. 217049.04 3-7 Site Assessment Report SECTION 3 — SITE ASSESSMENT We do not anticipate that stormwater quantity facilities will be required for the proposed site improvements. The site improvements comprise less than 1% of the contributing drainage area and flows to South Fork of the Rivanna River at the point of analysis. Based upon this analysis the site meets the requirements set forth in Virginia State Code 9VAC25-870-66 for water quantity. 3.4 Estimated Probable Cost An estimated probable cost for the project was generated based upon the conceptual layout. The estimate includes the construction of the new access road, parking area, and the proposed site improvements. The estimated total project cost is approximately $700,000. A copy of the estimated total project cost worksheet is provided in Appendix C. The estimated total project cost does not include stream and wetlands delineation, mitigation, or permitting. Albemarle County, Virginia Monacan Landing WWA Project No. 217049.04 3-8 Site Assessment Report SECTION 4 —CONCLUSIONS &RECOMMENDATIONS 4.1 Conclusions The purpose of the Monacan Landing site assessment is to assist Albemarle County in determining the feasibility for developing the subject property for use as a public park and boat launce. The project improvements consist of parking and access for 29 vehicles and pedestrian walking trails. The Monacan Landing property is situated on Tax Map 45, Parcel 66B and comprises approximately 21.67 acres. The property is located at the corner of Route 29 and Rio Mills Road along the South Fork of the Rivanna River below the reservoir. The following conclusions were determined for the project site: ■ The project area for the site lies within the 100-year FEMA Floodplain and stream buffer. ■ The 100-year FEMA Floodplain serves as the stream buffer for the site since it is located within the Rural Area as defined on the Comprehensive Plan. The 100- year FEMA Floodplain extends further than 100 feet from the top of the associated stream bank for Moores Creek. ■ A Conditional Letter of Map Revision (CLOMR) will need to be performed to determine the impacts to the FEMA Floodplain for any fill areas. ■ The site lies within the Entrance Corridor for Albemarle County and will require review and approval from the ARB. ■ A determination will need to be made by Albemarle County if the parking area for the proposed park is an acceptable use within the stream buffer. ■ A wetlands and stream delineation will need to be performed to determine the impacts to any jurisdictional wetlands and the South Fork of the Rivanna River. ■ A critical slopes waiver will be required for any impacts incurred as part of the proposed improvements. Albemarle County, Virginia Monacan Landing WWA Project No. 217049.04 4-1 Site Assessment Report WA SECTION 4 -CONCLUSIONS &RECOMMENDATIONS ■ Permanent restroom facilities will need to be located outside of the 100-year FEMA Floodplain in accordance with the Albemarle County Stream Buffer Ordinance. ■ The estimated total project cost is approximately $700,000. The estimated total project cost does not include stream and wetlands delineation, mitigation, or permitting. 4.2 Recommendations Based upon the conclusions reached with the site assessment we offer the following recommendations: ■ Recommend placing the parking area adjacent to Route 29 to reduce the amount of any required fill as well as providing an extra sense of safety. ■ Recommend grading out the existing embankment at the boat launch area to provide easier access. ■ Recommend placing the forested area on the site into a conservation easement to satisfy the stormwater quality requirements for the associated improvements.
