The City of LA contracts with BUILD TENNIS to build $3$ tennis courts on Los Feliz Blvd where a vacant lot currently exists. Karenna, the owner of a tennis raquet shop located right next to the vacant lot, is thrilled by the prospect of the courts bringing additional customers to her store. At the last minute, BUILD TENNIS backs out of the contract. Karenna is furious.

What can Karenna do to enforce her rights?
