36

Field Lighting

impact of lights on surrounding residential properties separate synthetic turf from lighting develop a list of priority candidates for conversion develop clear lighting standards

PLANNING CONTEXT

In 2002, the first full synthetic field was installed at Gunston Park.

In 2003, a citizen/staff Synthetic Grass Working Group submitted their recommendations regarding conversion of athletic fields from natural grass to synthetic grass.

As a result of this report, several fields were identified as candidates for synthetic surfacing, and some of them were converted.

In the County adopted 2005 Public Spaces Master Plan, the first guidelines for synthetic conversion were developed.

Today, the County has 15 existing synthetic fields. 3 field conversions are planned at: Gunston Park (2018), Wilson School (2022), Long Bridge Park field #2.

The current Adopted FY 2017 – FY 2026 Capital Improvement Plan calls for 4 synthetic turf fields conversions (locations: TBD).

SYNTHETIC TURF FIELD PROGRAM

2005 Public Spaces Master Plan Recommendations


Convert a minimum of one natural grass field per year to synthetic grass based on the analysis and recommendations of the 2003 Synthetic Grass Working Group.

All synthetic grass conversions should have existing lighting or a plan for installing “dark sky” lighting as a part of the synthetic grass installation.

Continue to explore new technologies and practices for managing and maintaining natural grass athletic fields.

FIELD LIGHTING-POTENTIAL MITIGATION MEASURES

59

Glare and Spill Reduction Techniques

- Shielding- Dimming controls- Wattage- Mounting height- Aiming angles

Design Techniques - Planting- Other physical buffers

Operational Techniques - Curfews- Limiting special events- Staff presence- No use of amplification- Seasonally-adjusted hours

County Board Approved Community Agreements and Standing Committees

- Formal Memoranda of Agreements with civic associations or partner organizations- Regular meetings

Summary of Feedback: Overall support for the draft measures Positive experience with MOAs, but they need additional enforcement Keep up with new technologies to increase light control

FIELD TURF & LIGHTING INSTALLATION –TECHNIQUES FOR TREE PRESERVATION

60

Fencing and signage, to reduce damage to roots and compaction of soil

Root pruning, to reduce mechanical damage from construction, outside of fenced area

Air spading to find roots and avoid damage

Root protection matting, where no excavation is occurring

Root growth hormone, applied after damage, to encourage root regrowth

61

GUIDANCE ON ATHLETIC FIELDS-SYNTHETIC CONVERSION & LIGHTING :

County Board supported the proposed major changes to the approach to synthetic field conversion and field lighting relative to the Preliminary POPS Draft

62

CASUAL USE SPACES APPROACH

CASUAL USE SPACES

POPS Draft:1.3 Ensure access to spaces that are intentionally designed to support casual, impromptu use and connection with nature.

63

Big Walnut ParkGlebe Park Long Bridge Park

Definition: Space that supports casual, impromptu use, including relaxation, reflection, informal activities, or connection with nature. May be generally available or only available at designated times.

WHAT TYPES OF SPACES SUPPORT CASUAL USE?

64

Casual Use Spaces Include:some available always, some at times

• open lawn with/without seating• grill/picnic areas (including shelters)• accessible forested areas• accessible landscaped areas• multi-use trails• plazas• esplanades• fields with community use• amphitheaters• schoolgrounds

Casual Use Spaces Do Not Include:

• multi-use, paved courts• community gardens• parking lots• spraygrounds• batting cages, dugouts• indoor or outdoor pools• permit only fields• skateparks• playgrounds• disc golf• outdoor tracks

CASUAL USE SPACES- PUBLIC FEEDBACK SUMMARY

Casual Use Spaces Overall positive feedback on the recognition of this type of open space Definition differences (What to include: fields, natural resources, always or

partially available, etc.?) How to measure? - Mapping & Level of Service How to design? - What amenities to include?

65Mapping Challenges-Barcroft Park Example

66

CASUAL USE SPACES- PROPOSED APPROACH

• Working with the POPS Advisory Committee to better define this term

• Highlight the need for this type of spaces as a priority

• Develop design characteristics

• Access standards (If these spaces can be inventoried): use access standards to determine where access to casual use spaces is lacking

• Perform access analysis for these spaces (if they can be mapped)

• Explore developing standards

Short Term (Include in the POPS document)

Long Term (Implementation item after POPS adoption)

How the PSMP Supports Enhancing and Creating Casual Use Spaces?

Benjamin Banneker Park Framework Plan adopted by the County Board in December 2017

What Are We Already Doing to Plan for Casual Use Spaces?

Short Bridge Park Master Plan adopted by the County Board in January 2018


67

GUIDANCE ON CASUAL USE SPACES:

County Board supported the proposed two-step approach: As part of the POPS document:

- acknowledge the importance of casual use spaces as an element of the public space system - develop definition and design characteristics

Implementation Phase (post-POPS adoption):- study access and explore development of standards

NATURAL RESOURCES & TREES APPROACH

68

NATURAL RESOURCES/TREES-PUBLIC FEEDBACK SUMMARY

Natural Resources Support for the Natural Resource Management Plan Update Impact of population growth & development on sensitive natural resources Access vs. impact of use Balance of recreation and resource protection Secure funding for protection, expansion & maintenance Land acquisition: prioritize expansion/protection of natural resources

Trees Support for the Urban Forest Master Plan Update Impact of development Loss of tree canopy & removal of mature trees Secure funding for tree protection and expansion Land acquisition: prioritize expansion/protection of trees

NATURAL RESOURCES/TREES-PROPOSED APPROACH

Update the Natural Resource Management Plan (NRMP) & Urban Forest Master Plan (UFMP) after POPS completion

70

Revise the POPS draft by strengthening recommendations on natural resources & trees

Update these plans (NRMP & UFMP) as one joint process which will review in more details specific policies related to natural resources and trees

NATURAL RESOURCES/TREES-PROPOSED APPROACH

Revise the POPS draft by strengthening recommendations on natural resources & trees & balancing what is more appropriate to be included in UFMP & NRMP

Impact of private development to be studied in the UFMP

Add data from the Tree Canopy Study in the final POPS document

71

Examples:

• 1.6. Ensure high-quality visual and physical access to the Potomac River, Four Mile Run, and their tributaries.

• 3.3. Protect, restore, and expand natural resources, particularly in riparian corridors along County waterways.

• 1.6. Ensure high-quality visual and physical access to the Potomac River, Four Mile Run, and their tributaries, while improving the tree canopy, native vegetation, and other natural resources along waterways.

• 3.3. Protect, restore, and expand natural resources, particularly in riparian corridors along County waterways.

• Make 3.3. a priority action.

• Add new: “Improve processes for earlier review of public projects, to minimize impact on tree canopy and natural resources”

GUIDANCE ON NATURAL RESOURCES AND TREES:

County Board supported the following proposed approach: As part of the POPS process:

- strengthen recommendations on natural resources and trees in the POPS document

After the completion of the POPS process:- update the Urban Forest Master Plan and Natural Resource Management Plan as one joint process which will review in more details specific policies related to natural resources and trees

PRIVATELY OWNED PUBLIC SPACES

VALUES AND CHALLENGES

75

Challenges: Public vs Private Spaces

• Who can use them? • Who's in charge of them?• Do private spaces feel less “public”?

Lack of complete inventory Lack of consistent signage Lack of guiding design principles

What are Privately Owned Public Spaces? Accessible to public Typically built as a tradeoff Supplement publicly owned spaces Provide opportunities for activity & interaction Provide respite from noise & hardscape in urban areas

RELATION TO POPS

• Plazas• Courtyards• Gardens• Walkways/ Mid-

Block Pedestrian Connections

• Landscaped Setbacks/ Wide Sidewalks

• Interior Pedestrian Connections or Atriums

PLANNING & LAYOUT

82

Size• Large enough to provide amenities and a meaningful

space for users.

Configuration• Main area should be regular in shape (square,

rectangular).• Minor areas can be irregular in shape- these could be

niches or transition zones.

Visibility• Clear sight lines into and throughout for safety• Site lighting • Visual surveillance- eyes on the street

PLANNING & LAYOUT

Liberty Center, BallstonLatitude Apartments, Virginia Square

ACCESS & CIRCULATION

84

Accessibility• Should be accessible for all users integrating

Universal Design Principles for all ages and abilities.

Access Points & Paths• Should have a minimum of two public entry/exit

points.• Avoid dead-ends and areas of entrapment.• Provide clear paths through site and to adjacent

building entrances.

Elevation• Locate public spaces on same level as adjoining

sidewalk.• Minor changes in elevation should remain open &

inviting from adjacent spaces.

ACCESS & CIRCULATION

USER COMFORT

86

Shade• Shade from buildings, trees, or other structures should be provided in

areas with high solar exposure.• Sun/shadow studies should be done in the design phase to determine

positive or negative impacts.

Lighting • Adequate lighting should be provided to create a welcoming and safe

place.• Avoid light pollution at night and utilize full cut-off lights or timers

where possible.• Utilize directional, path lighting to light circulation paths or ground

plane lighting can help animate the space at night.

Wind, Noise- provide protection from unwanted external noises

USER COMFORT
