This is one thing the founders of SeaWeed Co., South Portland's first marijuana store, did not see coming in their approval hearing with the city.

Last week, South Portland approved the store to begin construction with the intention of opening next fall 2019. They added a warning to keep an eye out for revolutionary soldiers' bones that may be buried on the property, according to the Press Herald.

They discovered the possibility of running into the soldiers' remains from two maps showing two Skillin family cemeteries on Running Hill Road, SeaWeed Co. explained in an instagram post. While they don't expect to find or interfere with ancient remains, SeaWeed Co. plans to place a memorial plaque on the property honoring the fallen soldiers' duty.

South Portland approved the business under two conditions, according to the Press Herald. One, that SeaWeed cannot sell marijuana until the state adopts laws for buying and selling weed for recreational use, which Maine voters approved in November 2016. Secondly, that SeaWeed follow state laws that protect historical burial grounds if one is found on the building site, said City Planner Steve Puleo. The latter condition would include notifying the state and local historical officials about the project, and if evidence of a cemetery were found, to properly rebury the bones in another established cemetery.
