PORTLAND, Ore. — A year-long program will bring 2,500 e-scooters to Portland streets starting Friday, according to the Portland Bureau of Transportation.

But there are changes to how and where they can be used.

This comes after a 4-month pilot program last year that brought just over 2,000 e-scooters to city streets, and clocked in more than 700,000 trips averaging 1.15 miles each. 

PBOT says last year's 120-day pilot program showed e-scooters can help reduce congestion and pollution. But on the flip side, there are concerns about riding them on sidewalks, which is a violation of state law, and parking them irresponsibly. Portlanders have mixed opinions about the scooters; some expressing excitement, others explaining their concerns.

Under the new year-long program, as many as 9,000 scooters could roll out by January 2020 if companies qualify for incentives, according to PBOT.

Bolt, Lime and Spin have initially been authorized to have scooters available, while four other companies - Clevr Mobility, Jump, Razor USA and Shared Technologies Inc. - are in the final stages of the permit process and will have their scooters on hand within weeks, city officials said.

New measures will be set in motion, intended to improve public safety, ensure service to East Portland and generate money for safety improvements.

PBOT is requiring companies to issue notifications, warnings, fines and account suspensions to people not using them legally. The transportation bureau says they will regulate and monitor illegal riding, and send that information off to the e-scooter companies, as well as audit and monitor companies’ incentives and penalties.

Riders will be charged a 25-cent street-use fee and companies will be charged a a 5 to 20-cent right-of-way fee to generate money to build safe places for e-scooters, such as protected bike lanes and greenways.

Scooter riders could be fined $50 for riding on sidewalks and $15 for illegally parking, after an initial warning from PBOT regulatory specialists.

Portlanders took more than 700,000 scooter rides in the initial four-month-long pilot program.

A report analyzing the first pilot program found 176 people went to emergency rooms over scooter injuries, most of which (83 percent) were not incurred in collisions with cars, scooters or pedestrians. 

Scooter riders are not allowed to ride in public parks, and are required by law to wear helmets.

Riding e-scooters in Tom McCall Waterfront Park was popular during last year's pilot program, and issues arose when people parked the scooters in the park and waterfront multi-use pathway. PBOT is requiring companies to use geo-fencing technology to stop people from parking scooters in the park and on the path. They say you'll get a warning and fine if you do it repeatedly.

PBOT is also marking off space for scooter parking throughout the city. 

However, legislators in Salem are considering a bill that would allow e-scooter riders to travel without helmets.

PBOT has created a scooter map of the city to educate riders on the safest streets to ride on and indicate where scooter riding is prohibited. The map is available online at: http://map.escooterpdx.com
