Chalk it up to neighborly love.

A California neighborhood has been covered in “Black Lives Matter” chalk drawings — in support of a young girl whose own signs kept getting destroyed by a middle-aged white man, according to reports.

Mom Manette Sharick went viral after she confronted a cyclist who had just poured water to erase the “Black” in the slogan her three-year-old daughter lovingly chalked on the sidewalk outside their home in Concord.

“I was shocked that someone could be purposefully doing this. It hurt a lot, it made me extremely upset,” she told CNN of the attacks almost every day over a week before the videoed confrontation.

As she reeled over what she called “such a blatant display of racism,” dozens of neighbors rallied around — and filled the sidewalks with similar “Black Lives Matter” chalk drawings and messages of support.

“I am deeply thankful and blessed for the special, unique, amazing people in my life who supported me, uplifted me and comforted me,” Sharick told CNN. “My family and I are grateful for the help and support we have received from the community.”

The confronted cyclist, only identified as “Jim,” has yet to return with his water bottles — but defended his initial actions.

“I’m not a racist,” he told KGO, saying he believes the initial “good intentions” of the BLM movement had been “hijacked.”

“I was only pouring across the word Black because I believe that all lives matter. I don’t care what nationality, sexual orientation or any of that, we are all human beings,” Jim told the station.
