SEE LONGITUDINAL PROFILE FOR LOCATIONS AND THICKNESS. 2 THE ROCK PORTION OF THE MIXTURE SHALL CONSIST OF RIVER COBBLE (MIN. ALLOWABLE D50 FOR COBBLE MATERIAL = 8 INCHES) OF COLOR WHITE, TAN, YELLOW, OR BROWN. THE VOIDS WILL BE FILLED WITH A MIXTURE OF SAND, GRAVEL, AND TOPSOIL. THIS COMPOSITION WILL RESULT IN A VERY RESISTANT, ARMORED SUBSTRATE THAT WILL BE CAPABLE OF WITHSTANDING MUCH GREATER SHEAR STRESS THAN THE COMPUTATION OF THE REQUIRED D50 WOULD SUGGEST. CLASS Al RIPRAP SHALL BE AN ACCEPTABLE ALTERNATE, SUBJECT TO COUNTY APPROVAL, AS LONG AS IT MEETS THE SPECIFIED SIZE REQUIREMENTS. NOTE - CLASS Al IS SPECIFIED BY VDOT TO HAVE A D50 OF APPROXIMATELY 10 INCHES. WSSI INVESTIGATION OF MATERIAL FROM MULTIPLE QUARRIES HAS FOUND ACTUAL D50 TO BE APPROXIMATELY 6.7 INCHES (THE LARGEST SIZE TYPICALLY PRODUCED AS ROCK CRUSHER OUTPUT). SPECIFICATIONS IN THIS PLAN ARE DESIGNED TO ACKNOWLEDGE AND ACCOUNT FOR THIS DISCREPANCY. 3 BANK RUN GRAVEL MAY INCLUDE UP TO 5% CLAY, SILT, AND/OR SAND, AND UP TO 25% COBBLE (D50 = 3" TO 8"). GRAVEL MUST HAVE NATURAL COLOR (WHITE, TAN, YELLOW, OR BROWN). 4 THE SAND PORTION OF THE MIXTURE SHALL CONSIST OF A WELL MIXED SAND PREDOMINANTLY 1.0 MILLIMETERS TO 2.0 MILLIMETERS IN SIZE, SUBJECT TO ENGINEER APPROVAL (I.E. WASHED CONCRETE SAND IS NOT REQUIRED). SAND MUST BE WHITE, TAN, YELLOW, OR BROWN IN COLOR. 5 THE TOPSOIL PORTION OF THE MIXTURE SHALL CONSIST OF 50% SIFTED, UNWASHED COARSE SAND (WITH FINES ALLOWED), 25% COMPOSTED LEAF/BARK MULCH, 25% MINERAL SILT OR FINER MATERIAL (STONE DUST FROM ROCK CRUSHING OPERATIONS OR ANY SILT/CLAY).

PROJECT DESCRIPTION THIS PROJECT INVOLVES THE PLANTING/RESTORATION OF APPROXIMATELY 1,275 LINEAR FEET OF AN UNINAMED TRIBUTARY TO MEADOW CREEK IN ALBEMARLE COUNTY, VIRGINIA. THE PROJECT AREA BEGINS NEAR THE PROPERTY LINE AT THE SOUTHEAST CORNER OF OUR LADY OF PEACE PROPERTY. THE STREAM FLOWS SOUTHWEST ON OUR LADY PEACE PROPERTY FOR APPROXIMATELY 500 LINEAR FEET BEFORE FLOWING ONTO THE REAR (SOUTHEAST) PORTION OF CHURCH OF THE INCARNATION PROPERTY. THE STREAM CONTINUES SOUTHWEST ON CHURCH OF THE INCARNATIONPROPERTY FOR APPROXIMATELY 750 LINEAR FEET BEFORE ENDING ON THE EDGE OF BRANCHLANDS COMMUNITY PROPERTY, APPROXIMATELY 150 FEET UPSTREAM OF THE EXISTING POND. THE PROPOSED DESIGN SEEKS TO PROPERLY RESIZE THE STREAM FOR CURRENT AN D PREDICTED WATERSHED CONDITIONS WHILE REESTABLISHING A CONNECTION WITH THE ADJACENT FLOODPLAIN. THE LIMITS OF DISTURBANCE (LOD) SHOWN IN THIS PLAN COVERS 66,314 SQ. FT (1.52 ACRES), INCLUDING USE OF ALTERNATE ACCESS 2. B. EXISTING SITE CONDITIONS THE 73 -ACRE CONTRIBUTING DRAINAGE AREA FOR THE WATERSHED IS CHARACTERIZED BY A MIS; OF COMMERCIAL, RESIDENTIAL, AND FOREST LAND TYPES WITH NEARLY HALF (45%) OF THE WATERSHED IN A FORESTED CONDITION, 22% AS IMPERVIOUS COVER, AND THE REMAINDER IN TURF. (WATERSHED DELINEATION AND LAND USE INFORMATION UTILIZED FOR THIS DESIGN WAS PROVIDED BY ALBEMARLE COUNTY STAFF). RUNOFF FROM UPLAND AREAS OF THE WATERSHED IS CONVEYED MAINLY THROUGH OPEN NATURAL CHANNELS ONCE IT ENTERS THE FORESTED RIPARIAN CORRIDOR UPSTREAM OF THE DESIGN REACH. UPSTREAM AREAS ARE RELATIVELY STABLE AND MAINTAIN GOOD CONNECTION WITH THE SURROUNDING FLOODPLAIN. AS THE VALLEY NARROWS SIGNIFICANTLY WITHIN THE DESIGN REACH, SEVERE DOWN CUTTING AND EROSION HAS RESULTED, DISCONNECTING THE EXISTING STREAM FROM THE LIMITED FLOODPLAIN. CHANNEL SLOPES AREA APPROXIMATELY 2 - 2.5% THROUGHOUT THE REACH. C. ADJACENT AREAS THE PROJECT ENTRANCE IS PROPOSED OFF OF INCARNATION DRIVE. THE MAJORITY OF THE PROJECT IS CONTAINED WITHIN PRIVATE PROPERTY OF OUR LADY OF PEACE ASSISTED LIVING FACILITY, CHURCH OF THE INCARNATION, AND BRANCHLANDS COMMUNITY. OFFSITE PROPERTIES NEAR THE PROJECT LOCATION ARE SINGLE FAMILY HOMES LOCATED ALONG CHAPEL HILLS DRIVE TO THE SOUTH OF THE PROJECT AREA. D. OFF-SITE AREAS THERE ARE NO OFF SITE WORK AREAS. E. CRITICAL AREAS THIS PROJECT IS LOCATED ENTIRELY WITHIN A STREAM CHANNEL; HOWEVER, THE DESIGN PRESENTED HEREIN PROPOSES TO STABILIZE THE CHANNEL USING NATURAL CHANNEL DESIGN PRINCIPLES, THUS IMPROVING THE WATER QUALITY OF THE DOWNSTREAM RECEIVING WATERS WHILE ALSO PROTECTING AND IMPROVING THE EXISTING SANITARY CROSSING TO PREVENT FUTURE FAILURE. F. SOILS THE SOILS LOCATED ON THE PROJECT SITE ARE WEDOWEE SANDY LOAM (94B) AND HAZEL LOAM (39D). THE MAJORITY OF THE SITE IS CATEGORIZED AS WEDOWEE. THESE SOILS ARE EXCESSIVELY DRAINED WITH MODERATE PERMEABILITY AND A MODERATE EROSION HAZARD. A SMALL PORTION OF THE SITE IS COVERED BY HAZEL LOAM. HAZEL SOILS ARE EXCESSIVELY DRAINED WITH A MODERATELY RAPID PERMEABILITY AND AN EROSION HAZARD CLASSIFICATION OF EXTREME. G. EROSION AND SEDIMENT CONTROL MEASURES 1. BEFORE ANY WORK COMMENCES, AN ON-SITE PRE -CONSTRUCTION MEETING SHALL BE HELD TO ENSURE THAT ALL AFFECTED PARTIES (DESIGN ENGINEER, CONTRACTOR, STATE OFFICIALS, OWNER, AND PROJECT MANAGER) FULLY UNDERSTAND THE CONSTRUCTION SEQUENCING. 2. MATERIALS AND METHODS USED IN CONSTRUCTION AND MAINTENANCE OF THE EROSION AND SEDIMENT CONTROL MEASURES REQUIRED SHALL CONFORM TO THE CONSTRUCTION STANDARDS AND SPECIFICATIONS IN CHAPTER 3 OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK (VESCH), THIRD EDITION, 1992, AS WELL AS ANY OTHER APPLICABLE LOCAL, STATE, AND FEDERAL REGULATIONS. 3. THE CONTRACTOR SHALL BE RESPONSIBLE FOR PROVIDING ANY ADDITIONAL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES THAT MAY BE REQUIRED BY THE COUNTY INSPECTOR, OR COMMENSURATE WITH THEIR SEQUENCE OF CONSTRUCTION, TO PREVENT EROSION AND SEDIMENT CONTROL RELATED DAMAGE TO PROPERTY OF OTHERS, ADJACENT AND/OR DOWNSTREAM WATERWAYS, OR TO THE PROJECT, DURING CONSTRUCTION AND PRIOR TO PERMANENT STABILIZATION OF ALL DISTURBED AREAS. 4. PRIOR TO ANY OTHER CONSTRUCTION ACTIVITIES, PERIMETER EROSION CONTROL MEASURES ARE TO BE INSTALLED (I.E. TREE PROTECTION FENCE AND STONE CONSTRUCTION ENTRANCE) AROUND THE LIMITS OF CLEARING. 5. WORK WITHIN THE STREAM AREA SHALL NOT COMMENCE UNTIL AFTER PERIMETER EROSION CONTROL MEASURES ARE APPROVED BY THE COUNTY INSPECTOR. NO IN -STREAM WORK WILL BE PERMITTED UNTIL SPECIFIED ,SEED AND MATTING ARE ON SITE. 6.

EXIIIBIIA,g Chapel Hills Stream restoration - Particle Size Analvsis During a site visit on September 18, 2017 engineering and ecosystem services staff from Wetland Studies and Solutions, Inc. evaluated the sediment composition of channel bed and banks throughout the Chapel Hills project area. Sediment was visually assessed for the entire 1,200+ linear foot reach to document any substantial changes and in order to allow selection of a representative site for pebble count data collection. Bed and bank materials were found to be generally gravelly with occasional finer deposits and periodic bedrock outcroppings visible at existing bed elevation. Channel materials were found to be consistent throughout the design reach, so pebble count data was collected at one representative location in the central part of the design reach (near tree 1285). The D50 particle size was found to be approximately 1.0 inch (27 mm). The complete data set is presented on this sheet.

Background During a site visit on September 18, 2017 engineering and ecosystem services staff from Wetland Studies and Solutions, Inc. evaluated existing channel conditions for the 1,200+ linear foot Chapel Hills design reach. The project area begins near the property line at the southeast corner of Our Lady Peace property. The strum flows southwest on Our Lady Peace property for approximately 500 linear feet before flowing onto the rear (southeast) portion of Church of the Incarnation property. The stream continues southwest on Church of the Incarnation property for approximately 750 linear feet before ending on the edge of Branchlands Community property, approximately 150 feet upstream of the existing pond. The 73 -acre contributing drainage area for the watershed (Figure 1, previous sheet) is characterized by a mix of commercial, residential, and forest, with nearly half (45%) of the watershed in a forested condition, 22% as impervious cover, and the remainder in turf. (Watershed delineation and land use information utilized for this design were provided by Albemarle County and verified by WSSI staff.) Runoff from upland areas of the watershed is conveyed mainly through open natural channels once it enters the forested riparian corridor upstream of the! design reach. Upstream areas are relatively stable and maintain good connection with the surrounding floodplain. The valley narrows significantly in the design reach and erosion has resulted in severe downcutting, disconnecting the stream from the limited floodplain. Channel slopes are approximately 2 - 2.5% throughout the reach. II. Hydrologic Analysis A hydrologic analysis was developed using the published USGS Non -Urban Regional Curves for the Piedmont Physiographic Province of Virginia (Figure 2). These curves were developed to predicted bankfull characteristics for streams with low watershed imperviousness (typically less than 5%) and must be adjusted to account for development in the Chapel Hills watershed. This may be achieved through application of an urban channel enlargement factor. The Center for Watershed Protection published a report on the impact of watershed development on channel enlargement. From this study, it is estimated that ultimate channel enlargement can take 50-75 yrs or longer from the time the watershed is fully developed. A plot depicting the ultimate channel size vs. watershed impervious area is presented in the article and given as Figure 3. Based on watershed imperviousness in the Chapel Hills watershed (approximately 22%) the resulting enlargement factor would be approximately 2. 1. Bankfull Channel Geometry as Predicted by the Non -Urban Regional Curves. Cross-sectional Area = 2.1 sf, Bankfull Width = 5.1 ft, Banfull Flow = 5.6 cfs Ill. Channel Sizing Using the adjusted cross-sectional area (2.1 sf x 2.1 = 4.4 sf) as predicted by the regional curves with enlargement factor adjustment, channel size for the bankfull channel was determined to be 7 ft wide and 0.7 ft deep (assuming a 3:1 design bank slope). These dimensions were determined by iteratively solving Manning's open channel flow equation with various geometry configurations. IV. Discussion of Design Alternatives When considering the Chapel Hills design reach in the context of Rosgen's channel succession model (Figure 4), the majority of the existing channel exhibits characteristics of a G -type channel, narrow and deeply incised, while other areas in the lower portion of the design reach have significantly widened, more characteristic of an F -type channel. It is anticipated that the channel will continue to widen (since further significant downcutting is prevented by existing bedrock). As the channel evolves into an F -channel accelerated bank erosion will destabilize adjacent trees further exacerbating bank erosion until a new bankfull floodplain terrace can be formed. Implementation of a Priority 1 (P1) restoration (Figure 5) would involve reconstructing the stream channel with a size appropriate for the current and predicted watershed conditions, but at an elevation which allows better connection with the adjacent floodplain. A P1 restoration provides the highest degree of channel stability and ecological benefit while limiting disturbance to the existing floodplain corridor. This design option can result in adverse effects on adjacent infrastructure due to elevated floodplain flows. This possiblity was investigated through development of a conceptual floodplain model and is further explained below. This approach likely involves significant quantities of rock (for grade in higher n tr coordination with control structures) and properly sized bed material to prevent against future downcutting since the channel would be elevated above the existing bedrock. This approach can resultconstruction vection costs, however coordina o i h County staff indicates potential sources of fill are locally available and in this case material import is favored over a net export design. A Priority 2 (P2) restoration involves excavation of floodplain material in order to create a bankfull floodplain at a lower elevation. This approach would likely involve major excavation and haul off, as well as significant disturbance to the surrounding riparian vegetation/trees. Project costs for this strategy could approach those :of a P1 design , however preliminary channel sizing indicates that the smaller design channel size (relative to existing channel width) may allow for bankfull bench creation without significantly widening the disturbance envelop. A Priority 3 restoration involves the creation of a limited bankfull bench and isolated bank grading to reduce shear stresses and bank erosion. This approach does not seek to achieve long-term stability for the reach as a whole, but rather focuses resources on areas of highest erosion, thus presenting a more cost-sensitve alternative. However, significant quantities of large rock may be necessary to provide localized long-term scour/erosion protection. The goal of this project is to select the optimal design solution which achieves long-term stability, minimizes impacts to the existing stream valley, and works within the limits of available funding. These goals will require a design which focuses closely on contractibility and a balance of cut/fill to minimize material import/export. Given design discussions with regard to other County projects and an availability of fill material, a Priority 1 design is deemed to be the preferred alternative due to improved long-term stability, ecological benefits, and cost advantages seen in allowing use of locally available fill. V. Preliminary Floodplain Analysis The project reach is not a FEMA -regulated floodplain and no flood flows are available from previous studies. A lumped -parameter, single basin watershed model was developed in HEC -HMS to estimate the 100 -yr recurrence interval flow rate. Land use characteristics were input based on County GIS data and the Elioak/Hazel/Glenelg loamy soils broadly classified as Hydrologic Soil Group C. The Soil Conservation Service Curve Number method was used to calculate peak runoff, with an assumed time of concentration of 20 minutes. Model results indicate a 100 -yr peak flow of 363 cfs. This flow value was then applied in a HEC -RAS hydraulic model steady flow simulation. Existing conditions surface information and proposed grading were used to generate HEC -RAS model cross sections and the extent of resultant flooding. These results were used to inform design decisions. Figure 3. Urban Channel Enlargement 149 03 I ffim 20.0 30 0. t t Sr (% 60.0 fto 704 80.0.
