Sinkholes
Over 20 sinkholes have opened up in the ground since last September.
The cave-ins, which range in size, have seen houses collapse and rivers run dry. And there is never any warning as to where and when the sinkhole occur.
A driver in the early-morning hours had an unexpected detour when they drove into a sinkhole in the South Valley.
This is the second such incident in the area this year.
The driver wasn't injured, but crews had to tow the car out of the hole that took up the entire southbound lane of Prince Street SE at Grape Avenue SE.
Expect traffic delays in the area until crews can assess the situation.
It's unclear how much of the line will have to be replaced.
City officials said the second hole opened about 11 p.m. Monday night, resulting in the loss of water, gas and sewer service to the neighborhood.
"Due to the prolonged loss of these utilities, the city's Department of Public Works is recommending the immediate evacuation of affected residents at addresses 2102 to 2163 N.4th Street," a city news release states.
Twenty-nine homes are affected. The evacuation is not an order, just a recommendation by the city.

A Harrisburg trash truck get stuck in a sinkhole in uptown this morning.
Officials shut off water to that section of the street as they prepared to tow the truck from the gaping hole around 11 a.m.
Officials did not have an idea when the road will reopen.
North County Transit District spokeswoman Deborah Castillo said one of their buses was stuck at Los Arbolitos Boulevard and El Camino Real around 8 a.m. Wednesday.
The driver, who was the only person on the bus at the time of the incident, was uninjured.
An Oceanside Water Department dispatcher said the sinkhole was caused by a water main break.
Around 400 residents were without water as crews worked. Water was expected to be turned back by 10 p.m. Wednesday, water officials said.
Traffic was being diverted away from those streets.

A storm caused a 20-foot sinkhole to form along Mountain View Drive in Lafayette on December 2, 2012.
In one instance, a giant sinkhole swallowed two lanes of a street in a residential neighborhood in Lafayette Sunday.
High water levels and a clogged storm drain in Lafayette Creek destroyed a portion of Mountain View Drive Sunday, creating a sinkhole where the road once was, Lafayette City Manager Steven Falk said.

Comment: Update - video footage of the enormous sinkhole in Ohio:
A man got out of his car just before it fell into a huge sinkhole in the middle of a La Center road early Saturday.
Just before 2 a.m., 47-year-old James Sandvik of La Center was driving down Northeast Charity Road when his car got stuck on the edge of a ravine that was caused by a wash out.
Sandvik got out of the car with minor injuries just before it plunged over the edge. The car then washed more than 1000 feet away as water continued to pour through a broken pipe caused by a plugged colvert, said Sgt. Alex Schoening with the Clark County Sheriff's Office.
The hole is at the 31000 block of NE Charity road, which connects to Lockwood Creek Road and runs south to Battle Ground. Traffic is detoured three miles and the road is expected to be closed for a long time.
Authorities urge drivers to avoid the area if possible.
