Opposition to the western segment (from I-5 to Carmel Valley Road) persisted. By 1991, the Del Mar Terrace Conservancy filed an appeal with the 4th District Court of Appeals after losing the lawsuit to the city of San Diego and Caltrans. The Sierra Club had also sued the California Coastal Commission. On July 16, 1992, the Sierra Club withdrew its lawsuit after the City of San Diego agreed to work to keep the Peñasquitos Lagoon flowing to the ocean and to restore a wetland area. Following the Sierra Club's settlement, the City of Del Mar raised an objection to the club's decision to accept a settlement, since the city had given a $7,000 contribution (about $ in dollars) to the case. The Sierra Club agreed to return the money in August 1992.
