No demolition, construction or land disturbance activities may begin until all perimeter erosion control measures have been installed as per Contract Drawings. Perimeter control devices include, silt fence, temporary stone construction entrance and tree protection fence. If clearing is required for installation of a particular measure, all other measures shown shall be installed first; clearing of the land necessary may then proceed. 2. Once all measures have been installed, the site shall be cleared and grubbed as necessary within the limits of disturbance as per the Contract Drawings. Efforts shall be made to minimize the amount of cleared area exposed at any given time. 3. Once clearing and grubbing is complete, any necessary topsoil stripping may begin. Topsoil shall be stockpiled on site in the stockpile areas per the Contract Drawings. The stockpile shall receive such temporary seeding measures as may be required. Any soil take offsite shall be stockpiled at locations with all required permits. If offsite location does not have all required permits, the contractor is responsible for obtaining all required permits. 4. Demolition, earthwork and construction operations may begin once topsoil has been removed and stockpiled. 5. Once perimeter erosion control measures are in place, construction activities for the may begin. 6. All pipes shall be installed in accordance with standard construction techniques. Only the length of trench in which pipe can be installed in one day's time shall be open at any time, with spoil material placed on the uphill side of the trench. Piping shall be capped at the end of each day's work to prevent sediment from entering. The trench shall be backfilled at the end of each day's work and the disturbed area seeded and mulched within seven (7) days of backfill. 7. All inlets shall have inlet protection installed immediately after installation. 8. Temporary soil stabilization shall be applied within seven (7) days to denude areas that may not be at final grade but will remain dormant for longer than fourteen (14) days, except for that portion of the site on which work will be continuous beyond fourteen (14) days. 9. Upon completion of final grading, permanent seeding, mulching and fertilization measures shall be employed on all disturbed areas. Permanent soil stabilization shall be applied within seven (7) days after final grade is reached on any portion of the site. All remaining erosion control measures shall remain in place until the entire site has been stabilized. EROSION CONTROL PLAN & STORMWATER MANAGEMENT PLAN RIVAN 153082 Page 4 10. Once permanent stabilization has occurred and approved by inspector, temporary sediment control measures shall be removed. Any areas disturbed by the removal of these measures shall be returned as closely as possible to original condition and seeded, mulched and fertilize 3.4 Maintenance and Sediment Disposal All sediment and erosion control measures shall be inspected upon installation, at least once every five business days and no later than 24 hours following a measurable storm event. Repairs to, or replacement of, measures shall occur immediately if necessary and accumulated sediment removed as needed. Sediment shall be removed from all erosion control measures when the sediment storage volume of the measure has become 50% full. All removed sediment shall be disposed of in an approved manner at the stockpile location or a location to be designated by the Engineer or Owner. Steps shall be taken at the disposal site to ensure that further sediment transport does not occur. Permanent or temporary soil stabilization shall be applied to denuded areas within seven days after final grade is reached on any portion of the site.

Permanent stabilization shall be applied to areas that are to be left dormant for more than one year. 4 Stormwater Management Plan This stormwater management plan (SMP) has been prepared in accordance with the Virginia Code of Ordnances. Drainage area maps are in Appendix B. A proposed biofiltration basin provides water quality compliance and water quantity compliance for the east drainage area. Bioretention design included in Appendix F. 4.1 Water Quality Requirements Virginia Runoff Reduction Method Spreadsheet (VRRMS) version 3 for new construction was utilized to meet water quality requirements outlined in section 9VAC25-870-63 of Virginia Code. Pre and post surface conditions for the site are summarized in the table below. Table 1- Site Surface Conditions The total phosphorous reduction required is 0.48 Ibstyr. The proposed bioretention basin achieves 0.51 Ib/yr reduction. The Site Summary Page from the VRRMS is attached in Appendix C. EROSION CONTROL PLAN & STORMWATER MANAGEMENT PLAN RIVAN 153082 Page 5 4.2 4.2.1 Water Quantity Requirements For water quantity evaluation the site was broken into two drainage areas, east and west, refer to Appendix B for the drainage area drawings. The east drainage area drains to the proposed bioretention system. Drainage from the parcel to the west is included in the east drainage area. The west drainage area drains to catch basins on Berkmar Dr. north of the intersection with Laurel Park Ln. Drainage from the multifamily homes on the west side of Berkmar Dr. and the empty lot to the east of Berkmar Dr are included in the west drainage area. The tables below summarize pre- and post -surface conditions for each drainage area. Table 2 - East Drainage Area Surface Conditions Table 3 - West Drainage Area Surface Conditions Channel Protection - East The methodology outlined in 9VAC25-870-66.B.3.a was used to meet channel protection requirements. Q_Developed<_I.F.*(Q_Predeveloped* QRVj _Predeveloped )/ KRVj _Developed The Runoff Volume for pre- and post -development were calculated using the SCS TR-55 method. The Peak Runoff was calculated using the graphical peak discharge method. To account for any runoff reduction due to permanent stormwater features, the VRRMS was used to determine an adjusted curve number. The full calculations are provided in Appendix D. A summary of the 9VAC25-870-66.3.a evaluation is shown below. The QDeveloped, 0.05 cfs, is less than the maximum allowable runoff, 0.47 cfs, from the site. I.F. (site > 1 acre): 0.8 QDev loped: cfs 0.05 RVDeveloped: Cf 330 QPre-Developed: cfs 0.26 EROSION CONTROL PLAN & STORMWATER MANAGEMENT PLAN RIVAN 153082 Page 6 4.2.2 RVPre-Developed cf 750 1.F.*(QPre-Deve1oped*RVPre-Developed)/RVDeveloped 0.47 Flood Protection — East The proposed bioretention basin will include additional surface storage to meet flood protection criteria. SCS graphical peak discharge was used to determine peak flows, and TR-55 to calculate the minimum storage volume required. The full calculations are provided in Appendix D. To maintain a predeveloped peak discharge of 5.6 cfs, a minimum storage volume of 2,352 cf is required. The proposed bioretention basin and additional surface storage will provide 2574 cf of storage. Thus meeting requirements for 9VAC25-870-66.C.2.b. At the 2-yr storm event, the peak outflow discharge is 0.92 cfs. With a 10 it wide broad crested overflow berm, the runoff velocity is 2.86 ft/s. Based on Table 5-14 of the Virginia Stormwater Handbook, for 5-10% slopes and assuming Kentucky Bluegrass, the permissible velocity is 4 ft/s. 4.2.3 Channel and Flood Protection - West The methodology outlined in 9VAC25-870-66.B.1.a and 9VAC25-870-66.C.1.a was used to meet channel and flood protection requirements. Rational method and Manning's equation were used to calculate the peak runoff to the existing storm sewer system on Berkmar Dr, and the peak flow at 1 % of the drainage area. Full calculations are provided in Appendix E. The storm sewer system on Berkmar Dr. consist of 15-inch concrete pipe. The future 10-yr peak flow to the existing storm sewer system on Berkmar Dr. is 5.02 cfs, which is less than the capacity of the storm sewer system of 6.93 cfs. Indicating that the existing manmade stormwater system can confine the 10-yr flow and convey the 2-yr flow without causing erosion. At the point where the drainage area of the site is less than 1 % of the total drainage area, the existing run off for the 10-yr storm event increases form 183 cfs to 185 cfs. This a 1 % increase in flow. It is unanticipated that the proposed project will cause erosion or flooding issues downstream.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrGs.usda.govtwps/ portal/nres/main/soils/healthn and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https:Hoffices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil Scientist (http://www.nrGs.usda.govtwps/portal/nres/detail/soils/contactus/? cid=nres 142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different Ll Custom Soil Resource Report management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into Iandforms or Iandform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha -Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.

See next page. G. Pollution Prevention Awareness (Describe training and procedures to provide awareness and compliance for all measures in this document; waste management, wash waters, prevention measures, etc.) The site superintendent is responsible for the day-to-day operations and will be the spill prevention and cleanup coordinator. They will designate other site personnel who will receive spill prevention and cleanup training. These individuals will each become responsible for a particular phase of prevention and cleanup. The names of responsible spill personnel will be posted in the material storage area and in the office trailer onsite. Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County Prevent and respond to leaks, spills, and other releases including procedures for expeditiously stopping, containing, and cleaning up spills, leaks, and other releases. The following good housekeeping practices will be followed onsite during the grading operations: • An effort will be made to store only materials necessary to do the job. • All materials stored onsite will be stored in a neat, orderly manner in their appropriate containers and, if possible, under a roof or other structure. • Products will be kept in their original containers with the original manufacturer's label. • Substances will not be mixed with one another unless recommended by the manufacturer. • Whenever possible, all of a product will be used up before disposing of the container. • Manufacturer's recommendations for proper use and disposal will be followed. • The site superintendent will inspect daily to insure proper use and disposal of materials onsite. These practices are used to reduce the risks associated with hazardous materials: • Products will be kept in original containers unless they are not re -sealable, • Original labels, and material safety data will be retained. • If surplus product must be disposed of, manufactures or local and State recommended methods for proper disposal will be followed. In addition to the good housekeeping and material management practices discussed in the previous section of the Plan, the following practices will be followed for spill prevention and cleanup: • Manufacturer's recommended methods for spill cleanup will be clearly posted and site personnel will be made aware of the procedures and the location of the information and cleanup supplies. • Materials and equipment necessary for spill cleanup will be kept in the material storage area onsite. Equipment and materials may include but not be limited to brooms, dustpans, mops, rags, gloves, goggles, kitty litter, sand sawdust, and plastic and metal trash containers specifically for this purpose. • All spills will be cleaned up immediately after discovery. • The spill area will be kept well ventilated and personnel will wear appropriate protective clothing to prevent injury from contact with a hazardous substance. Prevent the discharge of spilled and leaked fuels and chemicals from vehicle fueling and maintenance activities (e.g., providing secondary containment such as spill berms, decks, spill containment pallets, providing cover where appropriate, and having spill kits readily available). Utilize double -wall fuel storage tanks. Create spill containment area by excavation or a straw bale perimeter lined with heavy duty plastic. Utilize tarp or fabric over plastic to protect from UV deterioration. Spill kits will be kept available for any spills outside the fuel storage containment area. Prevent the discharge of soaps, solvents, detergents, and wash water from construction materials, including the clean-up of stucco, paint, form release oils, and curing compounds (e.g., providing cover (plastic sheeting or temporary roofs) to prevent contact with stormwater; collection and proper disposal in a manner to prevent contact with stormwater; and a similarly effective means designed to prevent discharge of these pollutants). Plastic sheeting/tarps will be utilized to protect forms/walls that contain form release agent or curing compound when potential for precipitation is present. All wash water used for clean-up of tools used for paint and other contaminating construction materials will be collected in spill proof containers and disposed of appropriately off -site by subcontractor performing said work. Minimize the discharge of pollutants from vehicle and equipment washing, wheel wash water, and other types of washing (e.g., locating activities away from surface waters and stormwater inlets or conveyance and directing wash waters to sediment basins or traps, using filtration devices such as filter bags or sand filters, or using similarly effective controls). If sediment is being tracked offsite along the roadway, vehicle treads may require washing before leaving the site. Wash water must be contained onsite by E&S measures such as silt fence and inlet protection. Refer to the contractor drawings for all proposed location of temporary construction entrances and vehicle wash locations. Direct concrete wash water into a leak -proof container or leak -proof settling basin. The container or basin shall be designed so that no overflows can occur due to inadequate sizing or precipitation. Hardened concrete wastes shall be removed and disposed of in a manner consistent with the handling of other construction wastes. Liquid concrete wastes shall be removed and disposed of in a manner consistent with the handling of other construction wash waters and shall not be discharged to surface waters. Concrete wash water shall be directed to a leak -proof system of containment. Minimize the discharge of pollutants from storage, handling, and disposal of construction products, materials, and wastes including building products such as asphalt sealants, copper flashing, roofing materials, adhesives, and concrete admixtures; pesticides, herbicides, insecticides, fertilizers, and landscape materials; and construction and domestic wastes such as packaging materials, scrap construction materials, masonry products, timber, pipe and electrical cuttings, plastics, Styrofoam, concrete, and other trash or building materials. Any and all waste materials will be collected and stored in a metal dumpster rented from a licensed solid waste management company. Dumpsters shall be covered during rain events and whenever the contractor is not actively working on site. The dumpster shall meet all local and any State of Virginia solid waste management regulations. All trash and construction debris from the site will be deposited in the dumpster. Prevent the discharge of fuels, oils, and other petroleum products, hazardous or toxic wastes, waste concrete, and sanitary wastes. The dumpster shall be emptied when full to ensure contents remain contained. The trash will be hauled to a permitted solid waste disposal facility. No construction waste materials shall be buried onsite. All personnel will be instructed regarding the correct procedures for waste disposal. The superintendent on site shall be responsible for seeing that the procedures are followed. Any and all hazardous waste materials will be disposed of in the manner specified by the County of Albemarle, and the State of Virginia Hazardous Waste regulations or by the manufacturer. Site personnel will be instructed in these practices and the superintendent on site shall be responsible for seeing that the procedures are followed. Address any other discharge from the potential pollutant -generating activities not addressed above. Non-stormwater discharges are prohibited from the site during the construction period. Any potential sources of non-stormwater discharges must be identified by the Contractor and measure must be taken to ensure that these discharges do not leave the site. Minimize the exposure of waste materials to precipitation by closing or covering waste containers during precipitation events and at the end of the business day, or implementing other similarly effective practices. Minimization of exposure is not required in cases where the exposure to precipitation will not result in a discharge of pollutants. Any and all waste materials will be collected and stored in a metal dumpster rented from a licensed solid waste management company. Dumpsters shall be covered during rain events and whenever the contractor is not actively working on site. The dumpster shall meet all local and any State of Virginia solid waste management regulations. All trash and construction debris from the site will be deposited in the dumpster. Section 7.

Page 24 of 26 S. Duty to mitigate. The operator shall take all steps to minimize or prevent any discharge in violation of this general permit that has a reasonable likelihood of adversely affecting human health or the environment. T. Need to halt or reduce activity not a defense. It shall not be a defense for an operator in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this general permit. U. Bypass. 1. 'Bypass," as defined in 9VAC25-870-10, means the intentional diversion of waste streams from any portion of a treatment facility. The operator may allow any bypass to occur that does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to ensure efficient operation. These bypasses are not subject to the provisions of Part III U 2 and 3. 2. Notice. a. Anticipated bypass. If the operator knows in advance of the need for a bypass, the operator shall submit prior notice to the department, if possible at least 10 days before the date of the bypass. b. Unanticipated bypass. The operator shall submit notice of an unanticipated bypass as required in Part III I. 3. Prohibition of bypass. a. Except as provided in Part III U 1, bypass is prohibited, and the board or department may take enforcement action against an operator for bypass unless: (1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage. Severe property damage means substantial physical damage to property, damage to the treatment facilities that causes them to become inoperable, or substantial and permanent loss of natural resources that can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production; (2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass that occurred during normal periods of equipment downtime or preventive maintenance; and (3) The operator submitted notices as required under Part III U 2. b. The department may approve an anticipated bypass, after considering its adverse effects, if the department determines that it will meet the three conditions listed in Part III U 3 a. Page 25 of 26 V. Upset. 1. An "upset," as defined in 9VAC25-870-10, means an exceptional incident in which there is unintentional and temporary noncompliance with technology -based state permit effluent limitations because of factors beyond the reasonable control of the operator. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. 2. An upset constitutes an affirmative defense to an action brought for noncompliance with technology -based state permit effluent limitations if the requirements of Part III V 4 are met. A determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is not a final administrative action subject to judicial review. 3. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or careless or improper operation. 4. An operator who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs or other relevant evidence that: a. An upset occurred and that the operator can identify the cause of the upset; b. The permitted facility was at the time being properly operated; c. The operator submitted notice of the upset as required in Part III I; and d. The operator complied with any remedial measures required under Part III S. 5. In any enforcement proceeding, the operator seeking to establish the occurrence of an upset has the burden of proof. W. Inspection and entry. The operator shall allow the department as the board's designee, the VSMP authority, EPA, or an authorized representative of either entity (including an authorized contractor), upon presentation of credentials and other documents as may be required by law to: 1. Enter upon the operator's premises where a regulated facility or activity is located or conducted, or where records shall be kept under the conditions of this general permit; 2. Have access to and copy, at reasonable times, any records that shall be kept under the conditions of this general permit; 3. Inspect and photograph at reasonable times any facilities, equipment (including monitoring and control equipment), practices, or operations regulated or required under this general permit; and 4. Sample or monitor at reasonable times, for the purposes of ensuring state permit compliance or as otherwise authorized by the Clean Water Act or the Virginia Stormwater Management Act, any substances or parameters at any location. Page 26 of 26 For purposes of this section, the time for inspection shall be deemed reasonable during regular business hours, and whenever the facility is discharging. Nothing contained herein shall make an inspection unreasonable during an emergency. X. State permit actions. State permit coverage may be modified, revoked and reissued, or terminated for cause. The filing of a request by the operator for a state permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any state permit condition. Y. Transfer of state permit coverage. 1. State permits are not transferable to any person except after notice to the department. Except as provided in Part III Y 2, a state permit may be transferred by the operator to a new operator only if the state permit has been modified or revoked and reissued, or a minor modification made, to identify the new operator and incorporate such other requirements as may be necessary under the Virginia Stormwater Management Act and the Clean Water Act. As an alternative to transfers under Part III Y 1, this state permit may be automatically transferred to a new operator if: a. The current operator notifies the department at least 30 days in advance of the proposed transfer of the title to the facility or property; b. The notice includes a written agreement between the existing and new operators containing a specific date for transfer of state permit responsibility, coverage, and liability between them; and c. The department does not notify the existing operator and the proposed new operator of its intent to modify or revoke and reissue the state permit. If this notice is not received, the transfer is effective on the date specified in the agreement mentioned in Part III Y 2 b. 3. For ongoing construction activity involving a change of operator, the new operator shall accept and maintain the existing SWPPP, or prepare and implement a new SWPPP prior to taking over operations at the site. Z. Severability. The provisions of this general permit are severable, and if any provision of this general permit or the application of any provision of this state permit to any circumstance, is held invalid, the application of such provision to other circumstances and the remainder of this general permit shall not be affected thereby.
