Cars on Porpoise Drive in Lakeway are going to have to go a little slower.

On June 18, the Lakeway City Council approved an ordinance reducing the speed limit on the road from 30 to 25 miles per hour.

The speed limit reduction was championed by residents who live on Porpoise Drive. All but two residents on the street signed a petition supporting the speed limit reduction.

State law allows a city council to reduce the speed limit on a road from 30 to 25 mph if it protects the general health, safety and welfare of the public, City Manager Steve Jones said.

"Normally city staff opposes adjusting speed limits unless it is warranted by a city study However, there are mitigating circumstances in this instance that ease this concern," he said.

Jones said the mitigating factors for a speed limit reduction on Porpoise Drive are:

The street is a cul-de-sac that does not accommodate pass-through traffic

The street has a golf cart crossing

The street wraps around a public park that is frequented by children

Almost all residents on the street support the speed limit reduction

The speed limit change will go into effect once the new speed limit signs are posted. Jones said he was not sure how long that would take.
