    AMENDMENT TO THE TOWN OF ARLINGTON DESIGN GUIDELINES
      MANUAL CHAPTER IV: SIGHT DESIGN AND SITE ELEMENTS, TO
     INCORPORATE LANGUAGE REGULATING THE USE OF COLORED
                       EXTERIOR LIGHTING

DATE:                     February 8, 2022
STAFF:                    Jeremy Credeur, Town Planner

SUBJECT:                  Amendment to the Arlington Design Guidelines Manual, Chapter IV

BACKGROUND:
As LED technology becomes less expensive designers have more flexibility in the way
buildings are lit. The use of colored exterior building lighting as accents is becoming more
prevalent. The concern of the overuse of colored lighting has been brought to staff’s
attention, as such discussions have been had between staff, and both elected and committee
members. These discussions have led to a proposal for an amendment of the Town’s Design
Guidelines concerning exterior lighting

PROPOSAL:
Design Guidelines Chapter IV specifically addresses site elements and their design; exterior
lighting is included in this chapter. Section C. Exterior Lighting provides applicants with
information on acceptable exterior lighting, from definitions and lighting levels to site
specific standards and requirements. Colored lighting was not addressed by the guidelines
as written.

The following language was added to address this:

In Section C. design criteria to be reviewed by the DRC are given which apply to all exterior
site lighting subsection 9. was added stating that all light should be natural white a
temperature range specifies the desired light color.

SECTION C, 9.

        9. All exterior lighting shall be natural white (3500-4500K). No colored exterior lighting of
           any type will be allowed.

                                                                                               February 8, 2022

Section C. continues by giving Site Specific Standards and Requirements. Details are provided
in sub-section 4. (Exterior Illumination of Building, Landscaping, and Signs) b., language adding
color temperature range is proposed giving further clarification of the desired lighting color. In
section 6. Prohibitions, the addition of part d. is proposed adding colored lighting as a
prohibited item.

SECTION C, EXTERIOR LIGHTING, Site specific Standards and Requirements 4. (b.)
     b.   The Town has a preference toward natural white (3500K-4500K) LED lighting of exterior areas in an
          effort to conserve energy.

SECTION C, EXTERIOR LIGHTING, Site specific Standards and Requirements 6. (d.)
     d.         Colored lighting (other than natural white 3500-4500k)

Exhibit A (attached) includes the full proposed language.

The intent of this proposal as mentioned above is to regulate the use of colored lighting to
prevent overuse of colored lighting and to provide clear direction of lighting color desired by
the Town of Arlington.

RECOMMENDATION:
The DRC is tasked to make a recommendation on the proposed amendment to take it forward
as written or take it forward with proposed changes.

The DRC’s recommendation will be forwarded to the Board of Mayor and Aldermen along with
the amendment for their consideration and a final decision.

                                                                                                              2

C. EXTERIOR LIGHTING – cont.

The Design Review Committee shall review a Lighting Plan
illustrating the style, location, height, and intensity of fixtures
proposed, in addition to a Photometric Plan illustrating
compliance with the required lighting levels. The following
design criteria shall apply to all exterior site lighting.

    1. Lighting levels should meet the minimum IESNA
       standards, and shall not exceed 200% of the
       recommended values.
    2. The maximum permitted pole heights for all non-
       residential applications shall be as follows: Perimeter
       Lighting (within 50-feet of residential property) -
       fourteen (14) feet; Interior Applications (50-100 feet
       from residential property) - twenty-five (25) feet;
                                                                        Accent lighting
       Interior Applications (over 100 feet from residential
       property) - thirty (30) feet. Generally, the height of
       light fixtures should be in proportion to the building
       mass. For the purposes of these standards, height shall
       be measured from the ground surface to the bottom of
       the lighting fixture.
    3. The lighting of a structure or parking area should not
       cast light beyond property boundaries, and shall not,
       under any circumstance, exceed one (1) footcandle at a
       commercial property line, or one-half (1/2) footcandle
       at a residential property line, and one- quarter (1/4)
       footcandle ten feet over the property line.
    4. Building mounted light fixtures shall not be located
       higher than the roofline, and shall have its lamp
       source shielded from view to minimize glare.
    5. The use of creative lighting, such as up-lighting,              Flush canopy lighting
       downlighting, accent lighting and façade lighting
       should be used to prevent glare with the fixtures
       being aimed away from the pedestrian or motorist.
    6. Lighting levels shall be based on initial lamp lumens
       and 1.0 maintenance factor.

    7. All lighting installations shall be maintained such
       that they continually provide acceptable luminance
       levels and glare control.
    8. All exterior illuminating devices shall be full-cutoff.
    9. All exterior lighting shall be natural white (3500-
       4500K). No colored exterior lighting of any type will
       be allowed.

For examples of acceptable and unacceptable light fixtures, see
Appendix C.                                                           Inappropriate parking lot lighting (sag/drop lens)

    AMENDMENT TO THE TOWN OF ARLINGTON DESIGN GUIDELINES
     MANUAL CHAPTER II: BUILDING DESIGN AND ARCHITECTURAL
      CHARECTER, TO AMMEND THE NONPERFERED MATERALS

DATE:                     February 8, 2022
STAFF:                    Jeremy Credeur, Town Planner

SUBJECT:                  Amendment to the Arlington Design Guidelines Manual, Chapter II

BACKGROUND:
The Town of Arlington’s Design Guidelines Manual Chapter II. gives applicants direction on
factors like design, architectural characteristics, compatibility with surroundings and
materiality. These items are of great importance to maintaining the aesthetic quality, as such
the use of durable materials that are timeless in design is a high priority for staff, board, and
committee members. In discussions with board and members of the various committees it
has been brought to staff’s attention concern with some of the approved secondary (20% or
less) materials.

PROPOSAL:
Concerns voiced were of both durability and an aesthetic quality of certain materials. From a
durability standpoint, concern with EIFS and Synthetic Stucco have been voiced, in particular,
issues with staining and cracking.

Other proposed changes include the removal of language allowing simulated materials that
give the appearance of primary materials. Along with the addition of language allowing
other materials to be approved on a case-by-case basis and cautioning that the architectural
style of the building should be considered when approving these materials.

The following proposed changes are intended to address these concerns.

        A. General Building Design Guidelines, 5.

                b. Secondary Building Materials: Secondary materials for exterior wall surfaces are intended
                   to provide interest and variety inbuilding design and may be used for up to 20% of the
                   elevations, exclusive of all windows, doors, roofs, and walk-way covers. Acceptable
                   secondary building materials include any material appropriate as a primary material,
                   cementitious stucco, precast concrete panels, exterior insulation and finishing systems (EIFS),
                   and high- quality architectural metal panels. Simulated materials that give the appearance of
                   the primary building materials listed in a., above, may also be used as secondary building
                   materials. Any stucco or EIFS should be at least 36 inches from grade and not in places

                                                                                                  February 8, 2022

                    where there will be regular contact with people or equipment. One a street facing façade,
                    EIFS should only be used for ornamental details only such as parapet caps, cornices, belt
                    courses, window details etc. Other Materials may be considered on a case by case basis. In
                    consideration of alternate materials, the Design Review Committee and the design
                    professional should consider the architectural style of the building and select appropriate
                    materials for the architectural style

Section A. General Building Design includes a section on Non-Preferred building materials
proposed changes to this section include the addition of exterior insulation and finishing
systems (EIFS) and synthetic stucco to this list.

      A. General Building Design Guidelines, 5.

          c.   Non-preferred Building Materials on non- industrially zoned properties, exclusive of all
               windows, doors, roofs, and walkway covers, include painted masonry units, natural gray
               smooth or textured concrete masonry units, corrugated metal siding, plywood, vinyl or
               aluminum siding, highly reflective glass curtain wall systems, exterior insulation and
               finishing systems (EIFS), synthetic stucco, and plastic materials (including fypon), or similar.

The final proposal is the addition of language allowing the use/approval of clear anodized
door and window framing be on a case-by-case basis. This proposed change stems from the
earth tone color palate prescribed by the DRC Guidelines being more compatible with
bronze or black window and door framing.

      A. General Building Design Guidelines, 5.

          f.   Door and window framing systems should blend with the overall design of the building. Bronze or black
               is preferred. Clear anodized or silver aluminum should be avoided unless it complements the overall
               color scheme of the building and shall be approved on a case-by-case basis.

In summary the proposed changes listed above are not intended to limit the creativity of
designers, but ensure lasting quality and timeless design that encompasses the intent of the
Design Guidelines.

RECOMMENDATION:
The DRC is tasked to make a recommendation on the proposed amendment to take it forward
as written or take it forward with proposed changes.

The DRC’s recommendation will be forwarded to the Board of Mayor and Aldermen along with
the amendment for their consideration and a final decision.

                                                                                                                   2

A.    GENERAL BUILDING DESIGN
      GUIDELINES

      1.   Building facades visible from a public right-of-
           way should be of high quality and finished in a
           manner that is consistent with the front façade.

      2.   Buildings that have long walls should use varied
           setbacks or architectural details to reduce the
           perceived length and mass of the building.

      3.   Development sites with multiple buildings
           should contain compatible design elements and a
           strong visual relationship between buildings.

      4.   Buildings should reflect the unique style of the
           Town and not develop according to a standard
           “corporate” or “franchised” style that is typically   High quality materials, unique architectural features

      5.   Exterior building materials shall be high quality
           and durable materials. Exterior building wall
           materials shall be subject to the following:

           a.   Primary Building Materials: The primary
                materials for exterior wall surfaces,
                exclusive of all windows, doors, roofs and
                walkway covers, shall be materials such as
                clay brick, natural or synthetic stone, wood,
                cast stone, and fibrous cement board
                (simulated wood siding like hardie-plank).
