By a vote of 3 to 1, the ARB forwarded a recommendation of no objection on the proposal, subject to conditions. See Attachment A for the staff report prepared for the May 11 review and Attachment B for the ARB action letter with recommended conditions from that review. REC's representative subsequently contacted staff and ARB members to state that the recommended conditions are unworkable and has asked for a second opportunity to present their proposal to the ARB with a goal of revising the recommended conditions of approval. For this second review, REC has provided a cover letter, additional information on Integrated Vegetation Management (IVM), and recommended language for an alternate ARB action. See Attachments C-E for this information. Since the May 11, 2020 ARB meeting, REC has completed its regular maintenance of the existing utility corridor, utilizing IVM. Some photos of that completed work are provided as Attachment F. The objectives of the draft IVM Plan indicate that, in the future, more low -growing native trees and shrubs would be allowed to remain below the electrical lines. If the ARB generally supports the IVM approach, the ARB may choose to forward a revised recommendation of "no objection" to the proposal with the condition that the IVM plan include proactive management to promote 1) native Virginia meadows, low growing shrub landscapes, and native species pollinators in the existing and proposed utility easement areas by suppressing forest succession, and 2) lower growing trees, grasses, wildflowers, and other vegetation that is compatible with safety needs and regulations and that is visually pleasing when viewed from the Entrance Corridor.

Context The power line runs along the west side of the corridor, through Rural Areas zoned parcels that contain a mix of wooded, residential and commercially developed properties. Visibility The existing poles and lines are readily visible from the Entrance Corridor. The proposed tree cutting and trimming will open up the view of the poles and lines. The taller poles will be visible from greater distances. The expanded area of tree cutting and the taller poles will result in increased visual impact. ARB Meeting Date May 11, 2020 Staff Contact Margaret Maliszewski PROJECT IUSTORY The ARB has not reviewed any applications associated with this power line. The existing poles were installed in 2009 to carry by -right distribution lines. They were designed to accommodate the proposed upgrade to higher -voltage transmission lines, which requires a Special Use Permit. Attach A REC ARB 5 11 2020 staff report.pdf PROJECT SUMMARY • Add pole toppers to each existing pole. (See Fig. 1 for an example of a completed project constructed in Greene County.) o Toppers average 35' in height o Exiting poles average 50' in height • Install higher voltage 115kV line. • Increase existing 40' easement to 75' with an additional 17.5' in the VDOT right-of-way and an additional 17.5' on private property. • No earth disturbance or grading is proposed. No additional poles are proposed. • Tree removal and removal of limbs overhanging into the area of the easement are proposed to allow for maintenance/repairs and to keep trees from touching the lines. Stumps and roots will be left in place. o The applicant's narrative states that, with sunlight increased in the cleared area, seeds already in the ground will be supported and this will grow, over time, into a native Virginia meadow and low -growing shrub landscape. o The narrative also states that REC will promote native species pollinator gardens in the additional 17.5 feet of right-of-way, but no specific design has been proposed. • The project narrative states that REC will work with individual property owners regarding landscaping preferences for their properties that do not interfere with powerline operation/maintenance, but there is no formal proposal for new landscaping. ANALYSIS This table lists the text of the Entrance Corridor Design Guidelines, issues identified by staff resulting from an analysis of the proposal based on the guidelines, and staffs resulting recommendations to the Architectural Review Board.

Applicants should note that replication of historic structures is neither required nor desired. 2 Visitors to the significant historical sites in the Charlottesville and Albemarle area experience these sites as ensembles of buildings, land, and vegetation. In order to accom lish the integration of buildings, land and vegetation Attach A REC ARB 5 11 2020 staff report.pdf characteristic of these sites, the Guidelines require attention to four primary factors: compatibility with significant historic sites in the area; the character of the Entrance Corridor; site development and layout; and landscaping. 3-5, 9- Compatibility with significant historic sites; Structure No buildings are proposed.

In other areas, existing wooded area that positively contributes to the character of the corridor will be reduced. There are clear limitations associated with screening utility lines and no screening devices are proposed. Given the size, height, and character of the poles and lines, traditional screening methods are not practical. However, negative visual impacts could be mitigated with the addition of landscaping in areas that currently lack vegetation or would have reduced vegetation after the proposed cutting and limbing.

Attach A REC ARB 5 11 2020 staff report.pdf SUMMARY OF RECOMMENDATIONS Staff recommends the following as the primary points of discussion: 1. Increased visual impact resulting from the increased height of the power poles and lines, tree removal, and limbing 2. Proposed treatment of the expanded easement areas 3. Other opportunities to mitigate visual impacts: new landscaping, additional expanded easements, planting and maintenance plans Staff recommends that the ARB forward the following recommendation on the Special Use Permit to the Planning Commission and Board of Supervisors: The ARB recognizes the need for a reliable power supply and the limitations associated with screening utility lines, as well as the opportunity to offset the increased negative visual impacts of REC's enhancement project in one of the County's primary Entrance Corridors. The ARB has no objection to the proposed use with the condition that landscaping is provided as follows, to the satisfaction of the ARB: I. Provide an analysis of the entire project area and identify planting areas, either within the proposed easements or within additional easements, that will be used to meet the Entrance Corridor Design Guidelines. Existing plant material may be retained to meet this requirement where possible. Plantings should be proposed in areas where no planting currently exists, where screening will be removed, in areas exposed to view by the proposed clearing, and where trees will be removed once the proposed wider clear zones are in place. 2. Provide an analysis of the entire project area identifying locations where the native Virginia meadow strategy and pollinator gardens will be implemented. Outline the steps that will be taken, beyond tree clearing and trimming, to establish and maintain the meadows, low growing shrub landscapes, and native species pollinator gardens.

I have also had several follow up meetings with Margaret and Scott Clark, who is the lead reviewer on the SUP application, about our interest in coming back before the Board to discuss the application again in an effort to collaborate with you on recommended conditions of approval that are workable for REC and the project. We appreciate the opportunity to continue this discussion with you on this important project for the community. In addition, since our ARB meeting on May 11, 2020, REC has carried out its five year maintenance of the right-of-way along the project boundary. I visited the site just a few days later and took a number of photographs of the conditions along the right-of-way corridor to document the maintenance, and I understand that Margaret and Scott have visited the area as well. We will be prepared to share samples of our photographs at the next meeting, and discuss REC's plan to continue utilizing Integrated Vegetation Management ("IVM") along the corridor in both the existing and proposed expansion of the easement area. We think that the photographs we have of the pre -maintenance conditions and the post -maintenance conditions will enable us to more effectively describe how IVM will be implemented, and how it is an appropriate plan for maintaining this corridor while also allowing REC to carry out the project and meet its obligations to protect the community from electrical outages caused by inappropriately managed vegetation. With that in mind, we have worked to identify ways that we might work with you to update the proposed conditions of approval to clarify that REC will implement IVM in the project area. REC has also begun the process of creating a corridor specific IVM plan, which I have enclosed. This draft IVM plan is in the early stages of development, and subject to further review and updates by REC and its team of certified utility corridor arborists, but it is our hope that it will provide a better explanation of how REC will utilize IVM to manage the vegetation along the Entrance Corridor and balance the objectives listed in the draft plan. We have also worked to update the proposed conditions to specifically refer to the plan, such that if the SUP is approved, implementation of the final plan would be a condition of approval of the SUP. We look forward to discussing this project with the Board in more detail in the coming weeks. Should you have any questions or comments that we can address in advance of the meeting, please do not hesitate to contact me. Again, we appreciate the additional time and Attach C REC applicant 10.16.2020 cover letter.pdf July 24, 2020 Page 2 guidance that each of you and Margaret and Scott have provided in connection with this important project.

Backaround: Unmanaged vegetation growing near power lines can damage electric facilities and cause problems with public safety, power supply, access, emergency service restoration, security, and lines of sight. It can also compromise compliance with environmental, legal, regulatory, and other requirements. Vegetation interference with power lines is one of the most common causes of electrical outages, as it can cause electric service interruptions when it contacts or comes sufficiently close to overhead high -voltage conductors to create an arc. Vegetation and conductors can come too close together when they are blown into one another by high wind or when lines stretch and sag due to high temperatures or heavy snow or ice buildup. Trees may also provide access for children and others to lines, potentially resulting in contacts that can cause serious injury or death. In light of the effect that tree -power line conflicts can have on public safety and service reliability, utilities are required to control vegetation growing in proximity to electric facilities. Proper vegetation management along utility rights -of -way ("ROW') is particularly essentially for avoiding problems attributed to poorly managed vegetation and overgrowth Integrated Vegetation Management ("IVM") is a practice of promoting desirable, stable, low - growing plant communities that will resist invasion by tall growing tree species, through the use of appropriate, environmentally sound and cost-effective control methods. IVM strategies are both integrative and site -specific and can reduce the environmental impacts on land, water, habitat and wildlife, and reduce environmental and human health risks in a more effective, safe, and cost-effective manner. Objectives REC's objectives in this IVM Plan are: • Implement environmentally sound, cost-effective control of vegetative species that potentially conflict with REC's electric facilities and infrastructure, while promoting compatible, early successional, sustainable plant communities which have myriad environmental, health, and social benefits. Attach D REC applicant 10 16 20 Draft Integrated Vegetation Management Plan.pdf DRAFT • Prevent outages caused by vegetation. Execute a proactive approach to prevent and reduce exposure to tree -caused power outages that balance all other Objectives. • Maintain access for its employees and contractors to safely carry out maintenance and repairs within the ROW, and minimize injuries due to slips, trips, and falls. • Facilitate prompt and safe restoration of electric service during emergencies and outages • Protect its infrastructure (including poles, wires, and transformers, among others). • Proactively manage to promote native Virginia meadows, low growing shrub landscapes, and native species pollinators in the existing and proposed utility easement areas by suppressing forest succession. • Promote lower growing trees, certain amounts of brush, grasses, wildflowers, and other compatible vegetation that is compatible with safety needs and regulations, and that is visually pleasing when viewed from the Entrance Corridor. Site Evaluation After managing this portion of its territory for many years, REC is very familiar with the site characteristics and conditions, which vary along the 1.6-mile span of the project. Some areas are wooded, some are developed with private residences and associated lawns and accessory structures, others are developed with small businesses and associated improvements such as buildings and parking lots. One parcel includes a house of worship and areas that are wooded and others that are open. There is a variety of Virginia upland mixed hardwoods, with excellent growing site conditions (excellent soil, drainage, and water). REC has assessed the height of its poles and lines, density of stems per acre, species, voltage, loading, and other site conditions. Trees adjacent to the line will be pruned based on projected growth which varies dramatically depending on species. For example, a maple tree may grow six to ten feet per year on a favorable site, while a cedar tree may only grow six inches. Trees within the right-of-way will be allowed to remain if they are low growing, compatible species such as redbuds, dogwoods, winterberry, serviceberry, etc. Trees that are incompatible, such as yellow -poplars, oaks, maples and other "timber -sized" species will be removed every five years. In addition, trees outside the right-of-way may be periodically assessed for health and vigor and selectively removed if they are found to be potentially dangerous. Some of the areas that currently have a "tunnel' effect created by trees that hang partially over Rt. 29, will be more open and be more visually pleasing after the vista is created between the road and new tree canopy line. 2 Attach D REC applicant 10 16 20 Draft Integrated Vegetation Management Plan.pdf DRAFT Based on this site evaluation, REC has determined that a five-year maintenance cycle is appropriate, along with a mid -cycle hazard tree inspection. The mid -cycle inspection will assess whether any hazardous situations have developed since the maintenance was carried out, and provide an opportunity to conduct appropriate remedial action to correct those situations. REC has a fiduciary responsibility to its member owners to minimize expenses associated with maintenance cycles, but the site characteristics of the project area are such that there is the potential for hazards to develop in less than five years. The mid -cycle assessment is designed to reduce these hazard risks. Action Thresholds Action thresholds for this project area are as follows: • Any plant species that has an ability to attain a height of 10 feet will be treated and/or removed at the time of the 5-year maintenance cycle. This clearance height will be sufficient to prevent flashover between trees and conductors, considering the combined movement of vegetation and conductors in high wind and sagging of conductors due to elevated temperatures and icing. Trees and other vegetation that are a compatible species and that do not typically attain a height of 10 feet may be left in place and pruned if necessary. • These guidelines will at all times be subject to the rights of, and shall not limit the rights of any person or entity other than REC, such as the owners of the subject parcels and any lessee, tenant, or easement holder other than REC or its successors, within the utility easement areas to carry . For any period of time during which such other persons or entities maintain their land by use of an alternative practice (such as mowing), Rappahannock Electric Cooperative's obligation to implement Integrated Vegetation Management shall be deemed satisfied with respect to any portion of the existing and proposed utility easement areas that is so maintained. Most dead or dying trees will be removed, and the wood will be left for the property owner, unless it is possible to leave a habitat tree that will not fall into a roadway or be a risk to the public. • If any dead or dying tree is not adjacent to a roadway or it would not otherwise create a safety hazard, there shall be consideration for leaving all or a portion of the dead or dying tree in place as wildlife habitat for raptors and other nesting animals. Trees occasionally can be left at 10-12 feet to become hunting perches for raptors or cavity nesting birds, if they will not pose a safety threat. This requirement is subject to, and does not limit, the land use rights of any person or entity other than Rappahannock Electric Cooperative or its successors. Such other persons or entities include the owners and any lessee, tenant, or easement holder other than Rappahannock Electric Cooperative or its successors, of any underlying parcel(s) 3 Attach D REC applicant 10 16 20 Draft Integrated Vegetation Management Plan.pdf DRAFT of land within the existing and proposed utility easement areas, who may desire to manage the land using alternative methods (such as mowing), provided that such alternative methods are consistent with REC's easement rights. Evaluation and Control Methods REC will work to achieve the Objectives of this Plan using the following control methods Manual Control Methods. Manual methods are performed by maintenance workers with hand carried tools, such as chain saws, hand saws, pruning shears, and other devices to control incompatible vegetation. These methods are selective and can be used where other methods are not appropriate. • Manual methods will be used in any environmentally sensitive areas within the project area, such as stream banks and critical slopes. Mechanical Control. Mechanical control methods are carried out using machines. REC will utilize mechanical controls where appropriate, such as bucket trucks with hydraulic saws combined with other mechanical pruning equipment. • Mechanical methods will not be used in any environmentally sensitive areas within the project area, such as stream banks and critical slopes. Trees adjacent to the line will be pruned based on projected growth which varies dramatically depending on species. For example, a maple tree may grow six to ten feet per year on a favorable site, while a cedar tree may only grow six inches. Trees within the right-of-way will be allowed to remain if they are low growing, compatible species such as redbuds, dogwoods, winterberry, serviceberry, etc. Trees that are incompatible, such as yellow -poplars, oaks, maples and other "timber -sized" species will be removed every five years. In addition, trees outside the right-of-way may be periodically assessed for health and vigor and selectively removed if they are found to be potentially dangerous. Some of the areas that currently have a "tunnel" effect created by trees that hang partially over Rt. 29, will be more open and be more visually pleasing after the vista is created between the road and new tree canopy line. Implementation Based on REC's assessment of the site and experience with the project area, it proposes a regular work schedule to achieve the Objectives of this Plan. REC will implement this Plan on a regular 5-year maintenance schedule with a mid -year inspection cycle. This schedule will include prompt monitoring and quality assessment as discussed in more detail below. 4 Attach D REC applicant 10 16 20 Draft Integrated Vegetation Management Plan.pdf DRAFT Monitoring and Quality Assurance Following each 5-year maintenance cycle, REC will continue to implement an inspection and quality control process to ensure that the Implementation of this Plan is consistent with the stated Objectives. • The entire length of the project area will be inspected on foot by an ISA certified arborist. • The inspection will assess whether any remaining hazards exist and confirm that this Plan has been effectively implemented • Monitoring may also be carried out by aerial assessment as well as foot patrols • Any areas not in compliance with this Plan will be promptly addressed and corrected, typically Inspection of completed work. • REC will utilize an electronic documentation system to confirm remedial actions comply with this Plan and are promptly carried out. As new information becomes available and as site conditions and circumstances evolve, REC shall reassess this Plan as appropriate, and provide any updated plan to the Director of Community Development or his or her designee. 43623273_1 5 Attach E REC applicant 10 16 20 recommended ARB conditions.pdf The ARB expresses no objection to the special use permit, subject to the following conditions: 1.
