It was inaugurated in June 2017 as the city's first new park in over 10 years.El Tecolote described the opening as "a hard-won victory for the Latino and Indigenous communities of the Mission, who have lobbied for years for its creation". The park's name, chosen by a community vote, means "My Little Town" in the Yucatec Maya language, and is also sometimes rendered together with its Spanish translation as "In Chan Kaajal (Mi Pueblito)". It reflects San Francisco's significant Mayan American minority, consisting of immigrants who since the 1990s arrived from Mexico's Yucatan region and settled mainly in the northern Mission and the Tenderloin.
Facilities include a playground, a gym for adults, a drought-resistant community garden, greenhouses, and a small stage for public performances on the central plaza. An interactive water installation commemorates Mission Creek, which used to run through the site. Artist Carmen Lomas Garza created renderings of a California condor and a great blue heron adorning the fence, commissioned by the San Francisco Arts Commission.
The park was constructed on a former parking lot, with a budget of $5.2 million. The planning process had begun in 2008 and saw city agencies partnering with a local grassroots organization named PODER (People Organizing to Demand Environmental and Economic Justice) and various neighborhood associations. As of 2017, a 126-unit affordable housing project is envisaged to be built on the remaining area adjacent to the park.
