Phase 1 shall include clearing of existing vegetation and grading operations to construct 47 proposed lots, roadway, and utility improvements. Size of Construction Project Total property acreage: 139.93 acres (Phase 1 -46.09 acres total) Total disturbed area: 27.64 acres Maximum area disturbed at one time: 27.64 acres Construction Support Activities N/A 2.4 Sequence and Estimated Dates of Construction Activities Phase 1. Notify Albemarle County to schedule a pre-construction meeting as required. 2. No erosion control measures may be removed during the construction process without the approval from the inspector on the project. 3. Contractor shall install tree protection fencing before any site disturbance shall take place. Contractor shall use tree protection fencing to stake out the limits of clearing and disturbance on-site. Contractor shall ensure that trees to be saved are flagged along the limits of clearing to ensure the proposed tree preservation acreage is met. Disturbance outside of the limits of clearing is solely permitted for the installation of the greenway, and mitigation plantings. The proposed greenway and mitigation plantings shall be installed without any clearing of existing trees. 4. Install the paved construction entrance with wash rack as shown on the plans. Construction entrance to be installed where construction vehicle routes intersect paved public roads, provisions shall be made to minimize the transport of sediment by (vehicular) tracking onto the paved surface. Where sediment is transported onto a public road surface, the road shall be cleaned thoroughly at the end of each day. Sediment shall be removed from the roads by shoveling or sweeping and transporting to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner. Install the wash rack uphill from proposed sediment trap #1. Acsa will determine the appropriate method of supplying the wash rack. Install the access from Westhall Drive and the parking and staging area with construction road stabilization. Construction road stabilization shall consist of 4"of 21a gravel in the parking area, and 8"of 21a gravel in any portion of the construction entrance which is unpaved. Parking and construction entrance areas shall be cleared of all vegetation, roots, or other objectionable materials before construction road stabilization is installed. A 2nd construction entrance shall be installed at Jonna Street following the same guidelines as above. Install the washrack uphill from sediment trap #3. 5 Stormwater Pollution Prevention Plan (SWPPP) WESTLAKE HILLS-PHASES I, II, III, & IV 5. Install the initial construction measures as shown on the phase I erosion control plan sheets. This includes 3 sediment basins and 5 sediment traps. Silt fence, culvert inlet protection, and diversion berms shall also be installed at this time. Stabilization measures shall be applied to earthen structures such as dams, berms, and diversions immediately after installation. Measures intended to trap sediment shall be constructed as a first step with any land disturbance activity and shall be made functional before upslope land disturbance takes place. 6. Install any remaining erosion control items as shown on the phase I erosion control plan. • CONSTRUCTION DISTURBANCES ASSOCIATED WITH THIS PHASE: o ESTIMATED START DATE: 8/4/2014 o ESTIMATED END DATE: 7/24/2015 • INSTALLATION OF STORMWATER CONTROL: o ESTIMATED DATE: 9/31/2014 • APPLICATION OF STABILIZATION MEASURES: o ESTIMATED DATE: 9/31/2015 • STORMWATER CONTROLS WILL BE REMOVED: o ESTIMATED DATE: 5/31/2015 Phase II 7. Once all the erosion control items have been installed as shown on the phase I erosion control plan and the inspector has approved the erosion control measures, the contractor can install the two permanent diversion ditches and begin grading operations. 8. Install the temporary pipe from STR 38 to sediment basin #3. 9. Install the temporary pipe from STR F58 to sediment trap #3 10. Install sediment trap #6 11. Rough grade the site to the contours shown on the erosion control plan. 12. 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. Temporary soil stabilization shall be applied within seven days to denuded areas that may not be at final grade but will remain dormant (undisturbed) for longer than 30 days. Permanent stabilization shall be applied to areas that are to be left dormant for more than one year. 13. Install the construction measures as shown on the phase II erosion control plan sheets. Measures intended to trap sediment shall be constructed as a first step with any land disturbance activity and shall be made functional before upslope land disturbance takes place. 14. Install the utilities, curb and gutter, and roads. Convert sediment basin #2 to sediment trap #7 upon inspector approval to allow the sanitary sewer and cul-de-sac to be installed. Inlet protection shall be inspected after each rainfall event and repairs shall be made as needed. If the stone filter becomes clogged with sediment so that it no longer adequately performs its function, the stone must be pulled away and cleaned and/or replaced. Install any remaining erosion control items as shown on the phase II erosion control plan. 15. Once the inspector gives approval the contractor shall install the remaining storm piping to the existing pond forebay and remove the temporary pipe to sediment basin 3. 16. Once the inspector gives approval the contractor shall install the outfall from STR F58 and remove the temporary pipe to sediment trap 3. 17. Once phase ii of construction is complete, the site is stabilized and the inspector has given approval, the contractor can remove the erosion control measures. No item shall be removed unless the upstream areas are stabilized and the inspector gives permission. 6 Stormwater Pollution Prevention Plan (SWPPP) WESTLAKE HILLS-PHASES I, II, III, & IV 18. Maintain all erosion control measures as specified in the Virginia Erosion and Sediment Control Handbook, removing only when approved by the local program administrator in accordance with the Virginia Erosion and Sediment Control Handbook. 19.

If you are covered under the 2012 CGP, this template will enable you to create an inspection report form that is customized to the specific circumstances of your project and that complies with the minimum reporting requirements of Part 4.1.7 of the permit. Note that the use of this form is optional;you may use your own inspection report form provided it includes the minimum information required in Part 4.1.7 of the CGP. If you are covered under a state CGP,this template may be helpful in developing a form that can be used for that permit; however it will need to be modified to meet the specific requirements of that permit. If your permitting authority requires you to use a specific inspection report form,you should not use this form. Notes: While EPA has made every effort to ensure the accuracy of all instructions and guidance contained in the Inspection Report Template, the actual obligations of regulated construction activities are determined by the relevant provisions of the permit, not by the template. In the event of a conflict between the Inspection Report Template and any corresponding provision of the 2012 CGP,you must abide by the requirements in the permit. EPA welcomes comments on the Inspection Report Template at any time and will consider those comments in any future revision of this document. You may contact EPA for CGP-related inquiries at cgp@epa.gov. Overview of Inspection Requirements Construction operators covered under the 2012 CGP are subject to the following requirements in Part 4: Inspection Frequency(see Part 4.1.4) You are required to conduct inspections either: • Once every 7 calendar days;or • Once every 14 calendar days and within 24 hours of a storm event of 0.25 inches or greater. Your inspection frequency is increased if the site discharges to a sensitive water.See Part 4.1.3.Your inspection frequency may be decreased to account for stabilized areas,or for arid,semi-arid, or drought-stricken conditions,or for frozen conditions.See Part 4.1.4. Areas That Need to Be Inspected(see Part 4.1.5) During each inspection,you must inspect the following areas of your site: • Cleared,graded, or excavated areas of the site; • Stormwater controls (e.g., perimeter controls, sediment basins, inlets, exit points etc.) and pollution prevention practices (e.g., pollution prevention practices for vehicle fueling/maintenance and washing, construction product storage, handling,and disposal,etc.) at the site; • Material,waste,or borrow areas covered by the permit, and equipment storage and maintenance areas; • Areas where stormwater flows within the site; • Stormwater discharge points;and • Areas where stabilization has been implemented. What to Check For During Your Inspection (see Part 4.1.6) During your site inspection,you are required to check: • Whether stormwater controls or pollution prevention practices require maintenance or corrective action, or whether new or modified controls are required; • For the presence of conditions that could lead to spills,leaks,or other pollutant accumulations and discharges; • Whether there are visible signs of erosion and sediment accumulation at points of discharge and to the channels and streambanks that are in the immediate vicinity of the discharge; • If a stormwater discharge is occurring at the time of the inspection, whether there are obvious, visual signs of pollutant discharges;and • If any permit violations have occurred on the site. Inspection Reports(see Part 4.1.7) Within 24 hours of completing each inspection,you are required to complete an inspection report that includes: • Date of inspection; • Names and titles of persons conducting the inspection; • Summary of inspection findings; • Rain gauge or weather station readings if your inspection is triggered by the 0.25 inch storm threshold;and • If you determine that a portion of your site is unsafe to access for the inspection,documentation of what conditions prevented the inspection and where these conditions occurred on the site Instructions for Using This Template This Field Version of the Inspection Report Template is intended to be used in the field and filled out by hand. If you will be filling out the Inspection Report Template electronically (i.e., you will be typing in your findings), please use the Electronic Version of the Inspection Report Template available at www.epa.gov/npdes/stormwater/swppp.The Electronic Version includes text fields with instructions for what to enter. Keep in mind that this document is a template and not an "off-the-shelf" inspection report that is ready to use without some modification. You must first customize this form to include the specifics of your project in order for it to be useable for your inspection reports. Once you have entered all of your site-specific information into these fields, you may print out this form for use in the field to complete inspection reports. The following tips for using this template will help you ensure that the minimum permit requirements are met: • Review the inspection requirements. Before you start developing your inspection report form, read the CGP's Part 4 inspection requirements.This will ensure that you have a working understanding of the permit's underlying inspection requirements. • Complete all required text fields. Fill out all text fields. Only by filling out all fields will the template be compliant with the requirements of the permit. (Note: Where you do not need the number of rows provided in the template form for your inspection, you may leave those rows blank. Or, if you need more space to document your findings,you may add an additional sheet.) • Use your site map to document inspection findings. In several places in the template, you are directed to specify the location of certain features of your site, including where stormwater controls are installed and where you will be stabilizing exposed soil. You are also asked to fill in location information for unsafe conditions and the locations of any discharges occurring during your inspections. Where you are asked for location information, EPA encourages you to reference the point on your SWPPP site map that corresponds to the requested location on the inspection form. Using the site map as a tool in this way will help you conduct efficient inspections,will assist you in evaluating problems found, and will ensure proper documentation. • Sign and certify each inspection report. Each inspection report must be signed and certified by the permittee to be considered complete. Where your inspections are carried out by a contractor or subcontractor, it is recommended that you also have the form signed and certified by the inspector, in addition to the signature and certification required of the permitted operator.The template includes a signature block for both parties. • Include the inspection form with your SWPPP. Once your form is complete, make sure to include a copy of the inspection form in your SWPPP in accordance with Part 7.2.12.4 of the CGP. • Retain copies of all inspection reports with your records. You must also retain in your records copies of all inspection reports in accordance with the requirements in Part 4.1.7.3 of the 2012 CGP.These reports must be retained for at least 3 years from the date your permit coverage expires or is terminated. Section-by-Section Instructions You will find specific instructions corresponding to each section of the report form on the reverse side of each page.These instructions provide you with more details in terms of what EPA expects to be documented in these reports.

If you are covered under EPA's 2012 CGP, this form will enable you to create a corrective action report that complies with the minimum reporting requirements of Part 5.4 of the permit. You are only required to fill out this form if one of the corrective action triggering conditions in Part 5.2.1 or 5.3 occurs on your site. Routine maintenance and repairs are generally not considered to be a corrective action triggering condition. Corrective actions are triggered only for specific, more serious conditions that are identified below in the "Overview of Corrective Action Requirements." If you are covered under a state CGP, this form may be helpful in developing a report that can be used for that permit; however it will need to be modified to meet the specific requirements of the permit. If your permitting authority requires you to use a specific corrective action report form, you should not use this form. Notes While EPA has made every effort to ensure the accuracy of all instructions and guidance contained in the Corrective Action Report Form, the actual obligations of regulated construction activities are determined by the relevant provisions of the permit, not by the form. In the event of a conflict between the Corrective Action Report Form and any corresponding provision of the 2012 CGP, you must abide by the requirements in the permit. EPA welcomes comments on the Corrective Action Report Form at any time and will consider those comments in any future revision of this document. You may contact EPA for CGP-related inquiries at cgp@epa.gov. Overview of Corrective Action Requirements Construction operators covered under the 2012 CGP are required to conduct corrective actions and report on progress made in correcting the problem condition(s) in accordance with the following requirements: Corrective Action Triggering Conditions(Parts 5.2.1 and 5.3) Corrective action is required whenever any of the following conditions occur at your site: • A required stormwater control was never installed,was installed incorrectly,or not in accordance with the requirements in Part 2 and/or 3; • The stormwater controls (e.g.,erosion and sediment controls or pollution prevention controls) that have been installed and maintained are not effective enough for the discharge to meet applicable water quality standards or applicable requirements in Part 3.1 of the permit; • A Part 2.3.1 prohibited discharge has occurred or is occurring;or • Any corrective actions required by EPA as a result of permit violations found during an inspection carried out under Part 4.2. Deadlines for Completing Corrective Actions(Part 5.2.1) You must complete corrective action (e.g.,installing and making operational any new or modified control, correcting errors in installation,preventing, mitigating,or cleaning up spills or leaks making repairs) by no later than 7 calendar days from the time of discovery of the condition. If infeasible to complete the installation or repair within 7 calendar days,you must document why it is infeasible and document your schedule for completing the corrective action as soon as practicable. Deadlines for Documenting Corrective Actions in a Report(Part 5.4) You are required to complete a corrective action report for each of corrective action you take in accordance with the following deadlines. • Within 24 hours of discovering the occurrence of a corrective action triggering condition,you must document the following: - The condition identified at your site; - The nature of the condition identified;and - The date and time of the condition identified and how it was identified • Within 7 calendar days of discovering a triggering condition,you must document the following: - Any follow-up actions taken to review the design,installation, and maintenance of stormwater controls, including the dates such actions occurred; - A summary of stormwater controls modifications taken or to be taken,including a schedule of activities necessary to implement changes,and the date the modifications are completed or expected to be completed;and - Notice of whether SWPPP modifications are required as a result of the condition identified or corrective action. Instructions for Using This Report Form This Field Version of the Corrective Action Report Form is intended to be used in the field and filled out by hand. If you will be filling out the Corrective Action Report Form electronically (i.e., you will be typing in your findings), please use the Electronic Version of the Corrective Action Report Form available at www.eaa.gov/npdes/stormwater/swppp.The Electronic Version includes text fields with instructions for what to enter. The following tips for using this form will help you ensure that the minimum permit requirements are met: • Review the corrective action requirements. Before you fill out this corrective action report form, read the CGP's Part 5 corrective action requirements.This will ensure that you have a working understanding of the permit's underlying corrective action requirements. • Complete a separate report for each condition that triggers corrective action. For each triggering condition on your site,you will need to fill out a separate corrective action report form. • Complete all required text fields. Fill out all text fields. Only by filling out all fields will the form be compliant with the requirements of the permit. (Note: Where you do not need the number of rows provided in the corrective action report form,you leave those rows blank. Or, if you need more space to document your findings,you may add an additional sheet.) • Sign and certify each corrective action report. Each corrective action report form must be signed and certified by the permittee to be considered complete. Where your corrective actions are carried out by a contractor or subcontractor,it is recommended that you also have the form signed and certified by the inspector, in addition to the signature and certification required of the permitted operator.The form includes a signature block for both parties. • Include the corrective action report form with your SWPPP. Once your form is complete, make sure to include a copy of the corrective action report form in your SWPPP in accordance with Part 7.2.12.4 of the CGP. • Retain copies of all corrective action reports with your records. You must retain copies of your corrective action reports in your records in accordance with the requirements in Part 5.4.4 of the 2012 CGP.These reports must be retained for at least 3 years from the date your permit coverage expires or is terminated. Section-by-Section Instructions You will find specific instructions corresponding to each section of the report form on the reverse side of each page.These instructions were written in order to provide you with more details in terms of what EPA expects to be documented in these reports. ii yt , 0 } e t' ¢t N� Si �filF jficitik ,..,�r �,:, ., r.

FWS National Wildlife Refuges (USFWS National Wildlife Refuges Program). There are no refuges found within the vicinity of your project. FWS Migratory Birds (USFWS Migratory Bird Program). The protection of birds is regulated by the Migratory Bird Treaty Act (MBTA) and the Bald and Golden Eagle Protection Act (BGEPA). Any activity, intentional or unintentional, resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by the U.S. Fish and Wildlife Service (50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)). The MBTA has no provision for allowing take of migratory birds that may be unintentionally killed or injured by otherwise lawful activities. For more information regarding these Acts see: http://www.fws.gov/migratorybirds/RegulationsandPolicies.html. All project proponents are responsible for complying with the appropriate regulations protecting birds when planning and developing a project. To meet these conservation obligations, proponents should identify potential or existing project-related impacts to migratory birds and their habitat and develop and implement conservation measures that avoid, minimize, or compensate for these impacts.

Migratory birds of concern that may be affected by your project: There are 15 birds on your Migratory birds of concern list. The underlying data layers used to generate the migratory bird list of concern will continue to be updated regularly as new and better information is obtained. User feedback is one method of identifying any needed improvements. Therefore, users are encouraged to submit comments about any questions regarding species ranges (e.g., a bird on the USFWS BCC list you know does not occur in the specified location appears on the list, or a BCC species that you know does occur there is not appearing on the list).

The U.S. Fish and Wildlife Service is the principal Federal agency that provides information on the extent and status of wetlands in the U.S., via the National Wetlands Inventory Program (NWI). In addition to impacts to wetlands within your immediate project area, wetlands outside of your project area may need to be considered in any evaluation of project impacts, due to the hydrologic nature of wetlands (for example, project activities may affect local hydrology within, and outside of, your immediate project area). It may be helpful to refer to the USFWS National Wetland Inventory website. The designated FWS office can also assist you. Impacts to wetlands and other aquatic habitats from your project may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal Statutes. Project Proponents should discuss the relationship of these requirements to their project with the Regulatory Program of the appropriate U.S. Army Corps of Engineers District. Data Limitations,Exclusions and Precautions The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information on the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A margin of error is inherent in the use of imagery; thus, detailed on-the-ground inspection of any particular site may result in revision of the wetland boundaries or classification established through image analysis. 10/13/2014 Information,Planning,and Conservation System(IPAC) Page 5 of 6 Version 1.4 nsmaltount U.S. Fish and Wildlife Service .1. '1/4.----:''''' .,.• Trust Resources List The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data and the amount of ground truth verification work conducted. Metadata should be consulted to determine the date of the source imagery used and any mapping problems. Wetlands or other mapped features may have changed since the date of the imagery and/or field work. There may be occasional differences in polygon boundaries or classifications between the information depicted on the map and the actual conditions on site. Exclusions - Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. Precautions - Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate federal, state, or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such activities.
