RE: Accessibility Concerns - Federal Post Office, 500 Main Avenue, Brookings, SD 57006
Dear Ms. Blechman:
2
I am writing on behalf of the Brookings Committee for People who have Disabilities to bring to your attention
accessibility concerns of the Federal Post Office building in Brookings, South Dakota.
Our Committee is appointed by the Mayor and advocates for the rights of people who have disabilities in our
community. The Committee strives to improve the quality of life for people who have disabilities through
enhancing the knowledge base of the community and to further serve as a community-based advocacy group
enhancing the ability of the community to comply with Federal Civil Rights legislation. Our group holds events
throughout the year to bring awareness and information to Brookings citizens. We also provide technical
assistance to the business owners, private individuals, governmental entities, and nonprofit organizations.
A local resident contacted the City of Brookings and our Committee regarding the accessibility of the Brookings
Post Office. Specifically, the complainant found it is very difficult and dangerous for someone in a wheelchair to
open the front door on the west side of the building due to the door swing.
In response, the Committee conducted multiple site visits at the Post Office and concurred with the complainant.
The following accessibility concerns were found:
1) The direction in which the door opens and the door placement relative to nearby columns and steps make
maneuvering from the accessibility ramp through dangerous for a person using a wheelchair or walker.
2) Worn hinges on the door result in intermittent sticking, which makes the door hard to pull open.
3) On the interior, all the customer counters are too high as were the counters in the service/preparation areas.
In response, the Committee proposed the following access solutions to Post Office officials:
1. Reverse the swing of the front door so that the door pulls from left to right. That way the opening is in
alignment with the ramp and is within the clear path of travel. However, closer inspection found that the door
swing couldn’t be corrected without installing a new system. So the Committee investigated the cost for this
solution and the estimated cost to replace the door and frame opening in the opposite direction would $4,208
- $5,250, depending on features and hardware incorporated.
2. Install an exterior automatic door opener on the building façade on the left side of the door unit. Although not
required, a truly accessible solution would be to install the automatic opener and the estimate for the system
and installation was $1500.
3. Reduce both interior doors’ opening force to 5 lbf or less by adjusting the hinges. The south interior door
required 15 lbf and the north interior door required 11 lbf. Or, install an interior automatic door opener inside
the vestibule for the south door that accesses the primary lobby space.
4. Lower one of the customer counters to compliant height and replace movable service tables with compliant
tables.
It should be noted when considering the cost to achieve these accessibility solutions listed above, that the
Brookings Post Office recently replaced its exterior ramp to correct a slope/grade issue, reportedly spending
$100,000.
The Committee tried working with the local postmaster and his regional supervisor, but was unsuccessful. Our
contacts at the Paralyzed Veterans of America in Sioux Falls and the Rocky Mountain DBTAC in Colorado Springs
suggested we contact your office for assistance in this matter.
Best regards,
Dave Miller

Durable Medical Equipment Drive Update (SD Cares). Miller reported that Easter Seals
no longer has an operation in South Dakota; however, the South Dakota Cares
organization based in Pierre is similar and would like to work with the Committee on this
project. The drive will be held from June 15 to 26. Mills Property Management will be
willing to donate storage space again this year. Wells noted that ADVANCE has an
abundance of used medical equipment and she will check to see if items could be
3
donated with this drive. Someone should also contact the Brookings Hospital about
equipment. Promotion ideas: Town & County Shopper, posters, booth display, public
service announcements.
Parking Brochure. Miller will coordinate with Wells on local pictures for the brochure
with hopes of going to print soon.
REPORTS:

ADA Review
Project: Children’s Museum of South Dakota & Senior Citizen Center Parking Lot
(Central Elementary School Building & Grounds)
Date: April 3, 2009
April 17, 2009 – Reviewed & approved by Committee
April 27, 2009 – Distributed
Participants:
Maree Larson, Larson Foundation mlarson@larsondoors.com
Suzanne Hegg, Museum Director,
Nancy Hartenhoff-Crooks, Member, Committee & SDSU Disability Services Coordinator
Jessie Kuechenmeister, Member, Committee
Allyn Frerichs, Park, Recreation & Forestry Superintendent (present for senior center lot discussion only)
Shari Thornes, Brookings City Clerk & City ADA Compliance Officer
(Primary Architect on Project - Lyle Pudwill, Landscape Architect, Confluence (lpudwill@thinkconfluence.com)
Project Details:
Group was invited to review the latest plans for the project. The Committee reviewed conceptual
and shell documents in the early stages on July 31, 2009 and items were noted in that report. This
report will provide comments on new issues or concerns.
A. Interior Spaces
1) Entrance:
Using automatic sliding doors in vestibule entrance.
Comment: Sliding doors is an excellent choice.
2) Food Atrium:
At this time the plans for the food area/deli remain undecided. If the owners
proceed with food service the Committee would re-emphasis accessibility of the
tables, food ordering/counters, self-service areas, path of travel, and the path of
travel surfaces.
3) Restrooms - Men‟s, Women‟s & Family Restrooms
Pursuant to Committee recommendations, the owner‟s design team have
implemented children‟s accessibility standards into the design by staggering sink
heights and incorporating accessible adult sinks & children height sinks in
design.
The family restroom was redesigned to also incorporate both sink styles and an
adult sized changing table as suggested by the Committee.
Comment: Construction documents that provide the greater level of details were not
available at this review. The Committee urged the project coordinators to be diligent in
monitoring measurements and dimensions related to final stall, fixture and amenities
installation paying particularly close attention to forward & side reach ranges, counter heights,
and clear floor space. Close monitoring is needed to prevent construction variances which can
occur due to final finishing/tile installation.
5
4) Meeting Rooms (Main level & 2nd level)
Pursuant to Committee‟s recommendations, the design now calls for roll-under
sinks in the meeting room/play areas.
5) Former Gym
Bleachers will be removed so those are a non-issue.
Lower level locker room will be removed so the area is all at-grade.
6) Elevator
The location of the elevator has changed, but remains the “hospital” size to
accommodate exhibit and patrons, but will have interior finishes of a pedestrian
elevator. No details on the elevator design yet.
7) Lockers
At the last review, the Committee noted if locking units were provided, some at
accessible height should be provided. The updated plans do not include any locking
lockers, so this is no longer an issue.
8) Stairs:
The plan is to retain the double stairway with terrazzo floors.
Comments:
Will the railing meet ADA requirements on height & extensions?
Is there a way to provide cues/warning surface in the stairway landings for people with
low vision?
9) Scent-Free:
Pursuant to Committee‟s recommendations, the design team has been investigating
materials and floor coverings that will minimize off-gassing of chemicals. The
terrazzo floor will be pre-finished as to never require additional waxing. After
construction, but prior to opening, the Museum will utilize multiple air exchangers
to rid and/or minimize any lingering fumes from the construction.
Comment: The Committee wants to re-emphasis the need for public facilities to be aware that
fragrances and scents are problematic to many individuals with disabilities. Many current-
day Veterans returning from active duty are extremely sensitive to chemicals and fragrances.
In addition to construction materials, other items to carefully consider are:
A. Selection of cleaning products.
B. Recommend not using scent-dispensers in the bathroom. Recommend installation of auto-
flush toilet systems and motion sensor for an automatic fan.
C. Consider a “scent free” policy for employees.
D. Consider promoting “scent-free” events.
B. Exterior Spaces
1) Parking
Senior Citizen Center Parking Lot (west side)
(8 Accessible – 2 are van accessible with a shared access aisle)
Comments:
6
Curb ramps with detectable warnings must be installed connecting the sidewalk in front
of the Center to all of the parking access aisles. Five aisles are currently shown in the
plans. Since the parking access aisles abut a curb/sidewalk, curb ramps connecting the
access aisles complying with 4.7 of ADAAG are required. This is required wherever an
accessible route (sidewalk) crosses a curb.
4.7 Curb Ramps.
4.7.1 Location. Curb ramps complying with 4.7 shall be provided wherever an accessible route crosses a
curb.”
“…4.7.7 Detectable Warnings. A curb ramp shall have a detectable warning complying with 4.29.2.
The detectable warning shall extend the full width and depth of the curb ramp.”
“ Accessible Route. A continuous unobstructed path connecting all accessible elements and spaces
of a building or facility. Interior accessible routes may include corridors, floors, ramps, elevators,
lifts, and clear floor space at fixtures. Exterior accessible routes may include parking access aisles,
curb ramps, crosswalks at vehicular ways, walks, ramps, and lifts.”
http://www.ada.gov/pcatoolkit/app1curbramps.htm
Truncated domes (Detectable Warnings [4.7.7]) are located at the edges of curbs to
provide a cue to people with vision impairments. Detectable warnings are intended to alert
pedestrians of an imminent hazard but are not designed as wayfinding devices. Research
indicates that the most effective detectable warning:
has a unique texture distinct from other common surfaces in the environment
adjoins or abuts the hazard to signal impending change
extends beyond the average stride length so that one can detect, understand, and
react to it before encountering the hazard
Since curb ramps remove this detectable drop-off, ADAAG requires a distinctive dome
patterning for the surface of curb ramps detectable by canes or by foot so that people with
vision impairments could detect the transition from pedestrian area to street. The Board
temporarily suspended the requirements for detectable warnings in 1994 due to concerns
raised about the specifications, the availability of complying products, maintenance issues
such as snow and ice removal, usefulness, and safety. The departments of Justice (DOJ)
7
and Transportation (DOT), which maintain enforceable standards based on ADAAG,
joined the Board in this action. As a result, the requirements for detectable warnings were
temporarily removed from the ADA standards. The suspension expired on July 26, 2001.
Consequently, the requirements for detectable warnings at curb ramps and
other areas are again part of ADAAG and the enforceable standards. For
additional information, see section 4.29 and an update on the status of these
requirements.
Other Items of Note:
Curb ramps and truncated domes are also required on the south end of the sidewalk
in front of the Senior Citizen Center where the sidewalk ends and accesses the parking
lot/alley.
Vertical signage is required designating accessible parking spots.
The Committee is producing an accessible parking brochure that provides guidance on
parking space and signage design. It’s in draft form, but will be included with this
report.
Vacated 4th Street Lot (500 block)
(34 spaces & 4 Accessible)
Comments:
Pursuant to the Committee’s previous recommendations, two additional spaces were
added on the north side of the street adjacent to the building. No details available on
accessible parking space design including curb cuts.
Same curb ramp, access aisle & truncated dome requirements as noted above.
Community Cultural Center (Carnegie Library)
Comments:
The entire corner will be redone in similar design to the downtown Streetscape project.
The proposed plan reviewed today did not show an accessible space. A new compliant
space must be installed in the same location with the same curb ramp, access aisle and
truncated dome requirements as noted above.
There may be slope/grade issues with the site. Committee recommends the design team
review the new “Public Right-of-way Access Advisory Committee – Special Report –
Accessible Public Right-Of-Way, Planning & Designing for Alternations” for guidance. A
complimentary copy is enclosed with the report.
Proposed Seating Area in former Substation Location
2) Path of Travel/Entrance/South Side
All exterior areas in this location appear to have an accessible path of travel with
a series of ramps, landings and handrail system to accommodate the six foot
slope in grade (southwest corner). Although the ramp slope will not require
railings, the design team is developing plans for a railing system in case one is
desired in the future.
All spaces will be connected by hard surface accessible path of travel.
8
3) Path of Travel/ History Timeline/Northwest Side
The use of the space has changed considerably from the July 2008 plan review.
The exhibit spaces and structures have been moved indoors and the exterior
space will be a „nature study‟ and natural prairie setting.
New features will include two tunnels for child play, one of which will
accommodate child size wheelchairs for history timeline to include:
o The river remains in the plan and pursuant to the Committee‟s
recommendations will be zero depth to accommodate wheelchair access.
o Bridges
o The earlier proposed Dinosaur Dig / depressed area with ramps also
remains. Use of elevated activities within this exhibit. An accessible
table will be located in this area.
o The Shelter/Pavilion and Ice skating pond also remain in the plans
The design team has selected the decomposed limestone as the primary path of
travel material. Fiber mulch will also be used in side areas.
Comments:
All areas of play activity and buildings must be connected by an accessible path of travel.
The Committee recommended the design team install a connecting path of travel to the
warming house and ice rink.
4) Neighborhood Park & Playground / North Side
The decision was made to retain the existing large playground equipment on the
north side for a neighborhood park. Accessible path of travel is provided from the
public sidewalk area on 5th Street and from the Museum facility.
5) Buses – Unloading Area
The plans do not include a bus shelter. The north side of 4th Street in front of the
museum will be designated for bus loading and unloading.
Accessible parking and passenger loading zones require aisles alongside parking and pull-
up spaces so that persons using mobility aids can transfer and maneuver to and from
vehicles. Wider aisles are necessary to accommodate vans equipped with lifts, which are
often mounted on the side but sometimes the back. Accessibility also includes the
appropriate designation and location of spaces and passenger loading zones, their
connection to an accessible route, and vertical clearance for vans. (ADAAG 4.6)
Passenger Loading Zones [4.6.6] - Where zones are specifically designed for passenger
loading and unloading, at least one on a site must be accessible. Recommendation: In
practice however, particularly at large facilities such as airports and university campuses
(which may be served by shuttles), it is recommended that passenger loading zones serving
all accessible entrances be accessible.
Aisles must be at least 5 feet wide, although a wider aisle (8 feet wide minimum) is
helpful at zones that serve transit vehicles with lifts or ramps. A level surface (maximum
2% slope in any direction) for both the space and aisle is important for wheelchair transfer
to and from vehicles and deployment of vehicle lifts or ramps. Where aisles are flush with
9
the pull-up space, wheelchair transfer is easier (the change in level of aisles at curb height
can make transfer very difficult).
As discussed in our meeting, we are attaching a copy of the Larson Ice Center exterior
plan that is scheduled for completion this year. The Center has incorporated a recessed
access aisle in the loading zone area in the same design that is being suggested for the
Museum (ENCLOSED).
Figure 503.3 Passenger Loading Zone Access Aisle
6) 5th Avenue & 5th Street Sidewalks & Curb Ramps
The plan will include new sidewalks and curb ramps along this area. Truncated
domes will also be required.
C. Programmatic
No programmatic documents regarding Museum policy or exhibit design were available at
this point in the project design.
Comments: The team applauds the overall building design and is hopeful that the educational
leadership team will be equally enthusiastic with taking into consideration access for people with
disabilities while creating an inclusive experience for museum patrons. The team would be happy to
meet with exhibit planners at the appropriate time. An online resource that we’d like to point out is
National Endowment for the Arts Office for AccessAbility.

ADA Compliance Review: Bike Trail Expansion Project
Dates:
March 24, 2009: Received Review Request from City
March 27, 2009: Presented plan overview to full Committee @ regular monthly meeting &
assigned subcommittee to review
April 6, 2009: Subcommittee Plan Review
April 17, 2009: Full Committee Review of Report
Reviewers:
Brookings Committee for People who have Disabilities Members: Dave Miller, Chair; Alan Davis,
Dona Kornbaum, and Dave Bertelson
Shari Thornes, City ADA Compliance Officer
Project Summary: The City of Brookings is planning to extend the existing bike trail an additional 3 ½
miles.
Trail Purpose/Definition: The proposed trail project is considered a “shared use trail.” Shared use
paths that allow bicycles, pedestrians and other non-pedestrian modes of transportation have their own
design and construction guidelines. The primary guide for bicycle and share use facilities is the
AASHTO (Reference Document #3 below). This guide has different requirements than those for
pedestrian use trail. A trail designed only to meet the proposed accessibility guidelines (Reference
Document #2 below) may not be adequate and possibly hazardous for bicyclists.
Source/Reference Documents Used in Review:
1) Americans with Disabilities Act Accessibility Guidelines (ADAAG)*
2) U.S. Access Board’s “Notice of Proposed Rulemaking (NPRM) for Accessibility Guidelines for
Outdoor Developed Areas” (2007) **
3) American Association of State Highway and Transportation Officials “AASHTO for Bicycle
Facilities”
* The ADAAG addresses the built environment and these guidelines don’t transfer well to the natural
environment. That is why it’s important to utilize multiple resources for guidance including consulting
with people with disabilities.
** An accessible trail is a trail that is accessible to and usable by people with disabilities. Accessible
trails are identified as meeting minimum guidelines established by the U. S. Access Board. The Access
Board is the federal agency responsible for creating guidelines and standards for accessible
environments. In June 2007, the Access Board issued a Notice of Proposed Rulemaking (NPRM) for
Accessibility Guidelines for Outdoor Developed Areas covered under the Architectural Barriers Act.
Eventually guidelines will be issued for those entities covered under the Americans with Disabilities
Act. During the standard development process, facilities need to use the "best available
information." For outdoor environments, the current best available information is the NPRM for
Outdoor Developed Areas. The remainder of this technical assistance paper will draw from the
NPRM.
Key Provisions of Trail Accessibility:
The group reviewed the following key issues related to trail accessibility as outlined in the Accessibility
Guidelines for Outdoor Developed Areas:
1) Surface
2) Clear Tread Width
3) Openings
11
4) Protruding Object
5) Tread Obstacles
6) Passing Space
7) Slope
8) Resting Intervals
9) Edge Protection
10) Signage
11) Curb Ramps & Detectable Warnings
Surface Types: Compliant
Required: See specifications below
Proposed: Majority of trail – asphalt or concrete, depending on price.
Wetlands area will be boardwalk, either treated wood or composite material
An accessible trail includes a route from accessible parking to the trailhead. Once on the trailhead, the
first issue addressed is surface. The trail surface must be firm and stable. Firmness refers to the
penetration of the surface that occurs when force is applied, for example when stepped on. Stability
on the other hand, refers to the displacement of the surface when a turning motion is applied to the
surface such as the twisting of a foot. In other words, firmness is a vertical measure of penetration
and stability involves how much surface material shifts when rotated pressure is applied. Examples of
firm and stable surfaces include concrete and asphalt. Soil stabilizers are sometimes used to make
otherwise inaccessible surfaces more firm and/ or stable.
****NOTE that “slip resistant” cannot be guaranteed in an outdoor environment. Weather
conditions will affect slip resistance.
Clear Tread Width: Compliant
Required: 36” inches
Proposed: Trail is eight (8) feet wide.
The clear tread width of an accessible trail must be a minimum of 36 inches. This allows a wide
enough area for a person using a wheelchair or scooter to comfortably stay on the firm and stable
trail surface.
Openings: Compliant
Required: ½ inch or less
Proposed: ½ inch or less
Openings in trail surfaces, such as spaces between the boards of a boardwalk. These spaces may not
allow the passage of a sphere one-half inch in diameter. In addition, the long dimension must run
perpendicular or diagonal to the main direction of travel preventing casters from wheelchairs, or tips
of canes from being caught in the spaces.
Protruding Objects Compliant
Required: 80” or more clear headroom
Proposed: 80” or more clear headroom (no overhead obstacles in plan)
Protruding objects are required to allow a minimum of 80 inches clear headroom space above the
trail. In other words, any protruding objects, including vegetation, must be above a minimum of
eighty inches from the ground. This space prevents people who are blind from bumping their heads on
tree branches or other objects hanging above the trail. Simple maintenance of trails is often the
solution to preventing accessibility issues resulting from protruding objects.
Tread Obstacles Compliant
12
Required: 2” maximum height
Proposed: None proposed
Examples of tread obstacles include tree roots, rocks, brush, downed trees or branches projecting
from the trail. Tread obstacles cannot exceed a maximum height of two inches. An exception occurs if
running and cross slopes are 1: 20 or less, then the obstacle may be three inches in height.
Passing Space Compliant
Required: 60 x 60 inches passing space occurring every 1000 feet
Proposed: Path already complies since its 8 feet wide the entire way
Passing space allows people who use wheelchairs to pass other hikers easily. Passing spaces need to
be a minimum of 60 X 60 inches and occur at 1,000 feet intervals when the clear tread width of the
trail is less than 60 inches. An alternative is a T-shaped space providing the arms and stem extend at
least 48 inches beyond the intersection. The T-shape still needs to occur every 1,000 feet, whenever
possible, the 60 X 60 space should be utilized to offer a more convenient way for people to pass one
another.
Slope SEE NOTE
Required: See below
Proposed: 5% or less
NOTE: One area of the plan currently cites a 5.77% slope; however, plan designers indicated
this would be corrected in the final plans.
This provision addresses two slopes that are crucial elements to people with mobility impairments—
running slope and cross slope. With the exception for drainage, the cross slope of an accessible trail
should be less than 1: 20. In addition, running slopes must comply with one or more of four provisions
with no more than 30 percent of the total trail length exceeding 1: 12.
- Running slope cannot exceed 1: 20 (5%) for any distance.
- If resting intervals are provided every 200 feet, the running slope may be a maximum of 1: 12.
- If resting intervals are provided every 30 feet, the running slope may be a maximum of 1: 10.
- If resting intervals are provided every 10 feet, the running slope may be a maximum of 1: 8.
Resting Intervals
Required: 60 inches minimum in length with slope of 5% or less
Proposed: No resting areas or benches are planned with the scope of this project; however, City
may add at a later date.
Resting intervals must be 60 inches minimum
in length, and have a width as wide as the
widest portion of the trail segment leading to
the resting interval. The slope may not exceed
1: 20 in any direction.
Edge Protection SEE NOTE
Required: If provided, minimum of 3 inches high
Proposed: Hard surface path – no edge protection
NOTE: Boardwalk area will have 2” x 6” edger with hand rails.
13
Guidelines state edge protection is not necessarily required, however where it is provided, it must
have a minimum height of 3 inches.
Signage SEE NOTE
Recommended: See Below
Proposed: NOTE: No signage other than signs at the crossings is planned at this time.
Recommend city consider installation of signage as described below.
Accessible trails should include signage with information on the total distance of the accessible
segment and the location of the first point of departure from the technical provisions. Although no
specific symbol has been chosen to represent an accessible trail one of the four examples displayed
here may be utilized.
Examples of signs that could be used to designate trails that fully comply with the accessibility
guidelines.
Curb Ramps/Detectable Warnings
Required: See details below
Proposed: The trail will cross intersections along LeFevre Drive, 32nd Avenue and SD Highway 14.
The plan calls for the installation of curb ramps and detectable warnings in all areas were
the path enters a street.
14
Curb Ramps [4.7]: Curb ramps complying with 4.7 are required wherever an accessible route crosses
a curb.
Slope [4.7.2]: The running slope of curb ramps cannot exceed 1:12. In alterations where it is
technically infeasible to meet new construction requirements, curb ramps may have a maximum
slope of 1:10 if the rise does not exceed 6 inches. It is important that transitions to curb ramps be
flush. Lips at the bottom of ramps, a common complaint, impede the momentum needed to
propel a wheelchair up-slope. Severe counter slopes can do the same thing and cause footrests
to scrape. Recommendation: While a 5% adjoining slope is allowed for drainage, gutters, and
roadway crowns, this slope should be minimized wherever possible (a maximum 2% slope is
preferred).
Width [4.7.3] and Surface [4.7.4]: The minimum clear width of a curb ramp is 36 inches, exclusive
of flared sides. Curb ramp surfaces, including flared sides, must comply with requirements in 4.5
for ground and floor surfaces be "stable, firm, and slip resistant." The cross-slope of the curb
ramp (2% maximum) must be minimized because it makes wheelchair travel difficult by
distributing weight and required force to one side and causing front casters to veer.
Sides of Curb Ramps [4.7.5]: Where pedestrians cross the ramp, curb cuts are required to have
side flares; sharp returns present tripping hazards. Returned curbs are acceptable where
pedestrian traffic across the ramp is discouraged.
Built-up Curb Ramps [4.7.6]: Built-up curb ramps are permitted where they do not project into
vehicular traffic lanes or access aisles at parking spaces and passenger loading zones. (The
surface of access aisles cannot slope more than 2% in any direction). Recommendation: Curb
ramps with returned sides or concave flares are preferred over built-up curb ramps with convex
flares because they provide greater edge protection.
Detectable Warnings [4.7.7]: The edges of curbs can provide a cue to people with vision
impairments. Since curb ramps remove this detectable drop-off, ADAAG requires a distinctive
dome patterning for the surface of curb ramps detectable by canes or by foot so that people with
vision impairments could detect the transition from pedestrian area to street. The Board
temporarily suspended the requirements for detectable warnings in 1994 due to concerns raised
about the specifications, the availability of complying products, maintenance issues such as snow
and ice removal, usefulness, and safety. The departments of Justice (DOJ) and Transportation
(DOT), which maintain enforceable standards based on ADAAG, joined the Board in this action.
As a result, the requirements for detectable warnings were temporarily removed from the ADA
standards. The suspension expired on July 26, 2001. Consequently, the requirements for
detectable warnings at curb ramps and other areas are again part of ADAAG and the enforceable
standards. For additional information, see section 4.29 and an update on the status of these
requirements.
Obstructions [4.7.8]: It is important that parked cars, lampposts, utility poles, and other
elements placed along sidewalks not obstruct connecting accessible routes. Space is needed at
the top and bottom of ramps so that people using wheelchairs can align with the running slope
and maneuver from ramps, including when making turns (which is difficult on sloped surfaces). At
curb ramps, a landing provides the necessary connection to an accessible route. A landing with a
minimum length of 48 inches will provide sufficient turning space. Where space at the top is less
than 48 inches, side flares must have a maximum slope of 1:12 instead of 1:10 at the curb face.

Location at Marked Crossings [4.7.9]: The foot of a curb ramp must be contained within the
crosswalk, where one is marked. At corners with a large radius, perpendicular curb ramps should
be located so that the centerline is radial to the curb face instead of being in line with the
crosswalk direction.
Diagonal Curb Ramps [4.7.10]: People using wheelchairs should not be directed into an active
travel lane in order to cross stopped traffic. A landing at least 48 inches long must be provided
outside the through-travel lanes if a diagonal ramp is used. Otherwise, perpendicular curb ramps
should be used. In addition, a segment of straight curb at least 2 feet long must be provided on
each side of the curb ramp and within the marked crossing.
Islands [4.7.11]: At traffic islands, wheelchair space between opposing ramps is essential. If
there is no level space between ramps, wheelchairs can "bottom out" or "high center" while
proceeding down one ramp while the back wheels are coming up the other slope. Cut-through
routes level with the street are necessary where wheelchair space between opposing ramps is
not available. Islands with cut-through routes must be wide enough (48 inches minimum) to
provide space for a person using a wheelchair.
Detectable Warnings [4.29]: People with little or no usable vision use environmental cues for safe
and independent travel. These cues may include ambient sounds, edges and other physical elements
that can be sensed by using a cane, and texture changes underfoot. Curbs are an important cue.
Where curbs are lacking, such as at curb ramps, vehicle drop-offs, and depressed corners at
intersections, people with vision impairments may not be able to discern the boundary between
pedestrian and vehicular areas. Detectable warnings, a distinctive surface pattern of domes
detectable by cane or underfoot, are used to alert people with vision impairments of their approach
to streets and hazardous drop-offs. ADAAG requires these warnings on the surface of curb ramps,
and at other areas where pedestrian ways blend with vehicular ways. They are also required along
the edges of boarding platforms in transit facilities and at the edges of reflecting pools not protected
by railings, walls, or curbs.
Suspension of Requirements (1994 - 2001): The Board temporarily suspended the requirements
for detectable warnings in 1994 due to concerns raised about the specifications, the availability
of complying products, maintenance issues such as snow and ice removal, usefulness, and safety.
This suspension applied to all requirements for detectable warnings except those at boarding
platforms in transit stations. The departments of Justice (DOJ) and Transportation (DOT), which
maintain enforceable standards based on ADAAG, joined the Board in this action. As a result, the
requirements for detectable warnings were temporarily removed from the ADA standards. The
suspension expired on July 26, 2001. Consequently, the requirements for detectable warnings at
curb ramps and other areas are again part of ADAAG and the enforceable standards. For
additional information, see the Board's update on the status of these requirements.

Detectable Warnings on Walking Surfaces [4.29.2] and Curb Ramps [4.7.7]: Detectable warnings
are intended to alert pedestrians of an imminent hazard but are not designed as wayfinding
devices. Research indicates that the most effective detectable warning:
has a unique texture distinct from other common surfaces in the environment
adjoins or abuts the hazard to signal impending change
extends beyond the average stride length so that one can detect, understand, and react
to it before encountering the hazard

The truncated dome specification and intended offset pattern was found to be the most effective
in providing a distinct patterning detectable by cane and underfoot. The degree of truncation,
which is not specified, varies according to the manufacturer.
Accessible Parking
No additional accessible parking is planned with this project.
Final Plan Review. It was noted during the review of the project, that the plans are not completed.
Pursuant to the City of Brookings Policy on ADA Compliance Review, ADA compliance officer will review
the project scope, final plans, and bid package of all new construction, remodels, and retrofits of City-
owned facilities and parks. The scope and budget development of capital improvement projects will
include the identification of ADA needs related to these projects to ensure compliance and accessibility
standards. A full copy of the policy is included as an addendum.
Why Accessibility?
There are more than 53 million Americans with disabilities in
the United States. This translates to one in five individuals
having some type of functional limitation that substantially
limits one or more major life activities. Recreation
opportunities give people with disabilities and people without
disabilities the opportunity to enjoy life, benefit from the
experience and contribute to their own sense of health and
wellness. Ensuring recreation opportunities are accessible,
such as trails, can create more opportunities for people with
disabilities to participate with their families and friends.
There is also a business aspect to providing programs and
facilities that are accessible to people with disabilities.
Accessible facilities and programs can increase the number of
prospective visitors, their family members and friends, thus
increasing participation and added revenue.

The ultimate goal is to provide trail
access for all to nature's wonders while
protecting the environment through
which these new trails pass.
