Do you have kids or just love skateboarding?

San Francisco is close to completing designs on a new, $1 million skate park in the north Mission District. It would be the second built in as many years and only the city's third overall.

If all goes as planned, the new park will be built on a shaded half-acre parking lot that sits beneath the freeway heading toward the Octavia Street off-ramp of Highway 101. The lot, at Mission and Duboce streets, has been a magnet for trash. A nearby parcel covered in asphalt would be replaced with a new basketball court and dog park.

Caltrans gave the land to the city as part of the construction of the off-ramp and the new Octavia Boulevard. The idea for a skate park emerged after neighbors lobbied for something that would bring activity to the large, concrete open spaces.

Skateboarding is popular in the city, yet illegal nearly everywhere other than neighborhood sidewalks. City law prohibits skateboarding on any city street and any sidewalk in any business district.

Rich Hillis in the Mayor's Office of Economic Development said that the city and property owners spend a lot of money on obstructions to keep skaters off their property. The city's first public skateboarding venue opened at the Potrero del Sol park in the south Mission in 2008 and has been wildly popular, Hillis said. A smaller skate park is located in Crocker Amazon.
