Topics for consideration:
• Some perspective . . .
• A brief rant.
• A question of priorities, and 5 recommendations.
• Stickier community designs.
• Putting the MAPPS strategies together.
• Why it really matters!

The rant: America’s looming chronic disease apocalypse . . .
mark.fenton@verizon.net
Diabetes Prevention Program(DPP; New.Eng.J.Med., April 2002)
Compared three treatments for nationwide cohort (3,000+) at risk for developing diabetes (elevated fasting glucose).
1. Control: Standard exercise and nutrition counseling; placebo.
2. Standard plus drug treatment: Metformin
3. Intensive lifestyle change: Nutritional training, 150 min./week physical activity.

My Rant:Change the conversation. It’s not just an obesity epidemic. At the core it is epidemics of physical inactivity and poor
nutrition.
mark.fenton@verizon.net
Recommendation 1:Think about scale &
effectiveness. Ask the simple question: in how many people is this likely to
actually change behavior?
mark.fenton@verizon.net
The bad news in just three numbers:
30 Minutes of daily physical activity recommended by national guidelines.
% of American adults who meet the S.G. recommendation (thru LTPA).
,000 Estimated annual deaths in America due to physical inactivity & poor nutrition. (2nd only to tobacco.)

mark.fenton@verizon.net
Surgeon General’s Report 1996 Physical Activity Guidelines 2008
• 150 minutes/week of moderate physical activity; more is better.
• Any activity is better than none.
• Can be broken up.
• 300 min/week for children.
• Reduced risk for CVD, diabetes, osteoporosis, dementia in old age, clinical depression, a growing list of cancers, obesity.

Recommendation 2:Go for breadth—not just
“exercise” for the actively inclined. We need increases
in routine, daily physical activity for everyone.
mark.fenton@verizon.net
Recommendation 2 (H.E.):Go for breadth—not just
getting people onto “diets.” We need increases in routine,
daily healthy eating for everyone.
mark.fenton@verizon.net
Pedometer-based “lifestyle” activity promotion:
• Measure steps all day.• Determine your
average daily steps. • Increase by only10%-20% a week.• Keep gradually
increasing . . .
Key to Success: Keep a record!

Social Ecology ModelDeterminants of behavior change
Sallis, Owen, “Physical Activity and Behavioral Medicine.”
• Individual (readiness, efficacy)
• Interpersonal (family, friends)
• Institutional (school, work, HMO)
• Community (networks, local gov’t)
• Public Policy (transport, land use)
mark.fenton@verizon.net
Socio-ecological successes?
• Tobacco – Education, kids, taxes, 2nd hand smoke policies/bans.
• Seat belts, child safety restraints – Media, training, laws, enforcement.
• Recycling – Kids, facilities, fees.• Water & sewer – Education,
ordinance & design requirements, inspection/enforcement procedures.

The “healthy” trip decision hierarchy*:
Walk
BikeTransit
Drive
*Nearly 25% of all trips are one mile or less; roughly
40% are two miles or less!(Nat’l Household
Transportation Survey)
mark.fenton@verizon.net
Recommendation 3:We have to make active living
& healthy eating the easier choices - actually safer, more convenient, less costly, and
even more fun than the alternatives.
mark.fenton@verizon.net
So, what does the research say matters?
1. Destinations within walk, bike, & transit distance?
2. Sidewalks, trails, bike lanes, safe crossings?
3. Inviting settings & sites for bikes, peds, transit?
4. Safe & accessible for all ages, incomes, abilities?

Or in Planner-Speak:
• Land use mix.• Network of ped,
bike, & transit facilities.
• Functional site design & details.
• Safety & universal access.

Compact neighborhoods
1. Land use. Schools, services near housing.
Mixed use,
multi-family.
& shared open space.
E.g. shopping, post office, library, . . .
Housing above retail

Schools
Pinellas Trail
mark.fenton@verizon.net
In other words, create & sustain village centers.
Laramie
Mix uses: keep where we live, work, shop, play, learn, pray . . . closer together!
“It’s not a neighbor-hood if you don’t have a corner store”(Indianapolis)
mark.fenton@verizon.net
2. Network encourages active travel with:
• Presence of sidewalks, paths, bicycle lanes.
• Shorter blocks, connect cul-de-sacs, more intersections.
• Access to trail, park, greenway, transit.
E.g., Kingsport, TN Greenway
Louisville

Transit riders are physically active.Besser, Dannenberg, Amer. J. Prev. Med., 29 (4), Nov. 2005.
Just during the daily walk to transit: • Half of transit riders
walk at least 19 mins.
• 29% get at least 30 mins. of activity.
• Minorities, poor (income <$15k/yr.), denser urban dwellers more likely to get 30+ mins./day.

3. Site design:
Market Po
Which setting is more appealing
for travel on foot and by bike?
mark.fenton@verizon.net
Site design?Research & practice suggest:
• Pedestrian friendly access; buildings are near the sidewalk, not set back.
• Trees, benches, water, aesthetics, lighting, scale.
• Details: bike parking, open space, plantings, materials.
mark.fenton@verizon.net
4. Safety. • Engineering can dramatically improve safety.
• Increasing pedestrian and bike trips decreases overall accident & fatality rates.

“But what about rural areas . . . ?”
1. Suburbia is steadily consuming the landscape . . .
mark.fenton@verizon.net
2. Rural areas are where you can
affect the shape of development
before it’s done!
“Rural” housing in SW Illinois?
mark.fenton@verizon.net
Community design & nutrition?
Farmer’s markets, green grocers.
Community gardens (near schools, parks, senior housing); conserving
farmlands; Community Supported Agriculture. Regulate fast food, drive-
through locations.
Olathe, KS
mark.fenton@verizon.net
Community gardens & farm markets can help overcome food deserts, but they’re not enough.
Need neighborhood grocers as well (co-ops, CSA’s, whatever it takes).

Recommendation 4:Both the built and social
environments of the community matter, so work on improving them. Start by helping people realize what “sticks” and what doesn’t.
mark.fenton@verizon.net
All the “health” benefits:Environmental
• Reduced traffic; air, water, & noise pollution.• Conserved open space, agricultural land.
Safety• Kids, elderly mobility.• Crime deterrent.
Social• Equitable transportation.• More personal connections.
Education• Increased safety.• Reduced transportation costs and infrastructure.• More community engagement; schools as neighborhood centers.

mark.fenton@verizon.net
Economic:• Residents shop locally; more stable tax base.• Healthy employees, low turnover, happy employers.• Healthy housing values(NAHB & NAR surveys).
Or more simply:< Which generates more tax revenue in the long run? ^
Marshalltown, IA
mark.fenton@verizon.net
Rec. #5: MAPPS strategy framework
• Media: Educate & build awareness, encourage behavior change.
• Access: Create “stickier” environments.
• Point of decision prompts: Promote, “nudge” toward the healthy, active choice.
• Price: Both ways (healthy choice affordable, unhealthy choices more expensive).
• Social support: Shift social norms (think smoking); inactivity, crummy eating the exception not the rule. (The oatmeal syndrome.)
mark.fenton@verizon.net
Media: Washington DC Free Ride promotion
• On the surface, a short term behavior change promotion: Get people to do more active commuting.
• At the core: Get employers to make sticky changes, subsidizing employee transit, flex time, lockers & showers. >
mark.fenton@verizon.net
Media: Topeka, KS PHC program has focused on policy.
• Jim Ogle, PHC team member, has modeled the change (WIBW):
• Dec. ‘08 – 3,700 steps/day
• Sep. ‘09 – 15,000+ steps/day!!!!!
mark.fenton@verizon.net
Topeka, KS PHC team:
• Focused on supporting the city’s “Fix the Streets” campaign – policy level change!
• Half-cent sales tax increment for roadway repairs.
• Then targeted Complete Streets policy statement by city council.
• Passed in Nov. 2009!!!
mark.fenton@verizon.netwww.completestreets.org
Accommodate all users:• Pedestrians• Bicyclists• Transit• Motor vehiclesDesign speed = posted speed.Few exceptions, clearly defined.Expand the hierarchy.
Access: Complete Streets Policy
mark.fenton@verizon.net
The real phases of CS policy implementation.
1. Passage of a policy resolution or executive order.
2. Adoption of DPW/engineering policy.3. Adoption of detailed roadway design
standards or guidelines. (Pirate’s code?)
4. Engineering practice (staff, consultants) actually entails routine inclusion of ped/bike/transit consideration in absolutely every project (including routine maintenance).
mark.fenton@verizon.net
Lane re-alignments• Often called road diets,
being seen more often.
• Can reduce collisions & severity.
• Dramatically improves performance for pedestrians & cyclists.

mark.fenton@verizon.net
• Site requirements: Max. setbacks & curb-cuts; limit drive-throughs.
• Subdivision rules: Curbs, sidewalks, road widths.
Access: Change the rules & ordinances.
• Zoning codes: Mixed uses, accessory dwellings, density bonuses.
mark.fenton@verizon.net
Point of decision prompts:
E.g. Stairway use efforts:• Open locked doors; signs.• Clean & paint, art, music.• Footprints, encouragement.• 3%-10% increase in stair use.
mark.fenton@verizon.net
Social support: E.g. Louisville, KY Pedestrian Planning & Summit
Series of community based workshops w/ walkabouts: School, community center, seniors, disabilities . . .
1. Learn; 2. Walk; 3. Work; 4. Plan & detail.
mark.fenton@verizon.net
Louisville Plan Kick-off Event w/:• Mayor Abramson• Health Dir. Dr. Troutman• Sewer Dist. Dir. Schardein
Why the walkabouts?• Inspiration – get engaged• Education – learn how• Practical planning, design
mark.fenton@verizon.net
E.g. Bus tours with key partners . . .
Hockomock Y, southeast MA.
Lexington, KY tour w/ developers, planners, elected officials.
mark.fenton@verizon.net
Safe Routes to School approach.
• Social support. Walking school busses, bicycle trains, safety education, promotion.
• Access. Construct remote drop-off area at park; relocate bus pick/drop.
• Point of decision. Improve trail through park; signs.
*Begin evaluating today; figure out where kids come from, how, & why!

Let’s really talk about “price:”• Economic stimulus $.
Which infrastructure?
• Transit funding. Rail, bus, van & car pool.
• Congestion charges. Auto disincentive.
• Tolls, parking, gas taxes? Carrot & stick.
• Insurance rewards for active commuting.
• 3rd quarter 2008. Auto miles 4.6% Transit use 6.5%

Omaha, NE health coalitionHiring an Active
Transportation Coordinator:
• First two years half-funded by Alegent Health (private sector partner).• Metropolitan Area Planning Association also funding.• Housed in City of Omaha Planning Department.
(True systems level change.)
mark.fenton@verizon.net
Healthy Eating tactics?
Policy: Overcoming food deserts through zoning & tax incentives to
encourage neighborhood groceries.
Access, price: Subsidized rotating farmers markets (target
at-risk neighborhoods).
PoD: Community gardens at schools.
mark.fenton@verizon.net
Why care about stickiness & active community design?
• The inactivity epidemic; our kids may pay!• ~4,000 pedestrian, ~40,000 motor vehicle,
~400,000 sedentary-related deaths/year.• Smog alerts, over an hour of average commute
time/day, traffic congestion and costs.• OPEC; drilling in ANWR; oil wars in Mid-east.• More eyes on the street, less crime.• Shopping locally, healthier housing values.• Higher employee retention, higher productivity,
lower health care costs.
mark.fenton@verizon.net
Keys to success:
• Policy, systems, and environmental change means increasing stickiness.
• Focus not on people reached and messages heard; focus ultimately on behaviors changed.
• Reach out to and fully engage (on their terms) partners in: education, planning, engineering, economic development, the business & development communities.
