The North Coast area contains the area between San Simeon and Monterey County border.

This small town has ingress and egress points at Highway 1 (north and south) and Old Creek Rd to the east. The northern end of the town is expected to incur major damage in the event of a large tsunami. The downtown area, including fuel stations, schools and the local fire station are all well within the inundation zone, as are many homes along the low-lying beach front properties.

The major ingress and egress points for Cayucos will be Highway 1 (north and south) and Old Creek Rd to the east. This portion of Cayucos is primarily residential, with a steep increase in elevation away from the ocean.

Northern Morro Bay is expected to suffer relatively heavily in a major tsunami, due to the low elevation in the neighborhoods off of Sandlewood Ave and the area around Cloisters Community Park.. Additionally the state park campgrounds located off of Yerba Buena St are likely to be inundated. NOTE: No address data is available for Morro Bay

In the event of a tsunami, Central and Southern Morro bay are expected to be some of the most severely impacted areas in the county. The sandspit will certainly deflect much of the energy directed at the coastline, but a relatively large amount of damage can be expected within the harbor.
NOTE: No address data is available for Morro Bay

The Los Osos area which would be effected by a tsunami is primarily residential in nature. The area is likely to have a moderate amount of inundation in the event of a tsunami. There are two primary areas which can expect damage, with isolated homes scattered along the coastline. Los Osos only has two roads for entrance/egress: South Bay Blvd to the north and Los Osos Valley Rd to the south. In the event of a tsunami, it is possible that portions of South Bay Blvd will be flooded or damaged, so Los Osos Valley Rd is advised to be primary the primary route for access and evacuation.

The Avila Valley area has a high tourist population which may lead to some complications with evacuations. Ingress and egress routes into the Avila area include Avila Valley Rd and San Luis Bay Dr. Additionally, San Luis Creek runs from the ocean near the downtown area of Avila Beach and continues up a canyon – predictions show possible inundation up this canyon, past Highway 101. However, this area floods on a regular basis and as such development near the creek is minimal; structure and infrastructure damage should be minimal.

At the lowest elevations, the downtown area of Avila Beach is primarily commercial development, with a combination of restaurants, shops and lodging. There is a large tourist population, which may require extra support when evacuating. There is only one egress path from downtown Avila Beach, Avila Beach Dr. This road follows a creek, and as a result is likely to be flooded and/or damaged as a result of a tsunami.

The Shell Beach area runs from the north end of Shell Beach to Dinasaur Park in the south. This area is primarily moderately dense residential, especially along the coastline. This area has relatively high cliffs which will likely take the majority of the impact of any tsunmai, but there are a few select areas which will likely have a damaging impact to structures.
NOTE: No address data is available for the Shell Beach area

Pismo beach is a relatively dense urban area, much of which is expected to be heavily impacted in the event of a major tsunmai. The downtown area and the mobile home parks to the south will likely have major damage, requiring a relatively large response. Highway 101/1 is in the expected inundation zone, which may prove problematic with regards to evacuation, however the damage expected should not cause structural damage – upon recession of the water, the highway should be usable.
NOTE: No address data is available for the Pismo Beach area

Oceano will have a relatively large amount of damage after a tsunami. The inundation area includes the Oceano Airport as well as many homes and businesses.
NOTE: No address data is available for the Pismo Beach area (the northern portion of this map)

The southern most section of coastline is very sparsely populated, and contains mostly state park land and agriculture. Much of this coastline is the property of CA State Parks.
