Fixture Specifications & Quantity Caps by Location

Guidelines for retaining wall construction, materials, and DRB approval thresholds on private lots.

The 18-Inch Height Threshold

• 18 Inches or Less (≤ 18"): DRB Application Exempt. Retaining walls constructed on private lots that are 18 inches or less in height do not require a Reston Association DRB application, provided they utilize approved materials, remain strictly within private lot boundaries, and do not adversely alter drainage.
• Over 18 Inches (> 18"): Mandatory DRB Application. Requires a formal RA DRB application and BWCA Board affected-party signature prior to commencing construction.

Approved vs. Prohibited Materials

• Approved: Natural stone (fieldstone, stacked flagstone) or landscape timbers properly pinned.
• Strictly Prohibited: Manufactured modular concrete block systems of uniform color/dimension, and bare cinder blocks.

Property Boundaries

All retaining wall structures and associated grading must remain 100% within deeded lot boundaries. Survey pin verification is required prior to construction. Encroachments on BWCA common ground are strictly prohibited and subject to mandatory removal at the owner's expense.

Approved shingle and shake materials, manufacturer profiles, colors, and venting specifications for all townhouse roofs.

Approved Roofing Systems

• DaVinci Composite Shake: Synthetic shake composite roofing specifically in the Aged Cedar profile (unanimously ratified by BWCA membership on Feb 12, 2020).
• Natural Cedar Shake: Natural wood shake meeting standard cluster exposure and fire-retardant rules.
• Architectural Asphalt Shingles: Dimensional architectural grade shingles in cluster-approved earthtones.

Venting & Flashing Details

• Ridge vents, plumbing stack boots, and drip edges must maintain uniform profiles across contiguous townhouse rooflines.
• Finished in dark brown or black to blend with the roof field.
• Visual coordination is required along party-wall step projections.

Governance & Anti-Circumvention

Individual DRB applications cannot circumvent democratically adopted cluster standards. The BWCA Board formally objects to and requests denial of non-conforming roofing submissions. Non-conforming roofs must be replaced to standard upon property resale or transfer.

2011 Trim Standard

IMPORTANT:
The following exterior trim standards shall not apply to original and approved trim already installed on townhouses prior to the date of adoption of these standards. These standards shall apply to any new or replacement trim installed after the date of adoption of these standards. All exterior trim on a townhouse does not have to be of the same material and of the same brand and manufacturer. However, there must be no discernable difference between materials once they are stained or painted.

Cluster standards for trim in Bentana Woods Cluster to include the following:

• Rough sawn cedar
• Pressure treated wood
• 5/4 HardieTrim® NT3TM Boards Smooth, or a comparable fiber-cement board product with DRB approval

with the following stipulations:

• That trim color be from the approved Bentana Woods Cluster color palette
• That trim have a uniform thickness with a minimum of 1” and a maximum of 2”
• That if only trim is being replaced the new trim dimensions must match the existing trim dimensions, and
• That if all siding and trim is being replaced the new trim dimensions must conform to the following chart that was submitted as part of the January, 2008 Trim Standard update:

*Please note that these dimensions vary between houses. Use the chart above as a guide and the owner may vary the width by +/- 2”

Standardized technical, architectural, and material definitions codified under BWCA Cluster Standards and Reston Association DRB guidelines.

• Slab: One flat panel construction featuring a continuous flat plane without raised moldings, recessed bevels, or decorative routings. Mandated for entrance and utility doors.
• Grain: The natural stratification, arrangement, and directional texture of wood fibers in natural lumber or simulated grain patterns embossed into composite materials.
• Texture: The tactile and visual surface quality of materials. Cluster rules mandate "smooth texture" for doors, garage, and trim, and "cedarmill" texture for siding.
• Privacy Glass: Obscured or patterned continuous glass panel that allows natural light while maintaining visual privacy. Must be one continuous panel without grids, grilles, tint, or stained glass.
• Capping (Trim Capping): Cladding exposed wooden window or door casings with custom-bent PVC, vinyl, or aluminum coil stock. Limited to ≤0.5" dimensional expansion and Oxford Brown color.
• Board-and-Batten: Exterior siding treatment consisting of alternating wide vertical panels and narrow vertical batten strips covering the joints.
• DRB (Design Review Board): The governing architectural review body of the Reston Association, established under Article VI of the Reston Deed of Dedication to administer protective covenants.
• Affected Party Signature: Procedural endorsement by an adjoining owner or cluster Board officer on an RA DRB application certifying notice receipt only. Does not constitute cluster approval or covenant waiver.
• DaVinci Composite Roofing: Synthetic shake roofing engineered to replicate hand-split cedar shakes with class-A fire resistance. Ratified unanimously by BWCA membership on Feb 12, 2020 in Aged Cedar.

This matrix maps cluster exterior projects to approval workflows, indicating whether an alteration is pre-approved, whether Board notification is necessary, whether an RA DRB application is required, and mandatory standard conditions.

*Note: Exact in-kind repairs conforming strictly to cluster standards require no DRB application. Any alteration, footprint expansion, or custom color requires RA DRB review and BWCA Board affected-party notification prior to work commencing.
