35% fines is proposed for this site since there are minimal environmental constraints on grainsize
and it is consistent with the natural fines content.
The beach fill material will be placed below the mean high tide line, as a layer over the beach
surface as a berm, or as a sand dike along the revetment as described in Section 3.1.2. The
beach-berm concept is shown in Figure 3-9. The typical berm would be elevated to near +12 feet
above MLLW and extended 125 feet seaward, then sloped at 10:1 (horizontal to vertical) to the
water. The high revetment located on the back of the beach allows for a higher berm elevation.
Timing and Placement Rate
Placement at the Oil Piers beach fill site is proposed for both Fall-Winter and Spring-Summer
placement (summer placement is between March 15 and September 15). It is proposed that two-
thirds of the sand can be placed during the winter months and one-third during the summer. This
allows for the sand to be introduced to the littoral cell similarly to the natural seasonal variations.
Since the winter season usually brings higher storms and rains, more sediment is transported to
the littoral cell from rivers, streams, and other watershed sources than during the summer
months. Therefore, the rate of sand placement for the 275,000 cy per year maximum annual limit
is 183,300 cy during the winter and 91,700 during the summer. This is outlined further in Table
3.1 for each site.
The Surfer's Point beach fill site is located within Seaside Park, in the City of San Buenaventura
in Ventura County (Figure 3-10). It is a beach that is heavily used by surfers due to direct
exposure to ocean swell. The beach along Surfer's Point is characterized by large cobbles and a
thin sand cover. Surfer's Point beach fill site is bordered by the Ventura River to the northwest,
the Pacific Ocean to the south, the Ventura County Fairgrounds to the northeast and Promenade
Park to the southeast. Recreational activities include surfing, windsurfing, sunbathing,
swimming, walking, and biking. A bike path leads along Seaside Park to the Ventura Pier. The
Surfer's Point Cobble Nourishment Project was recently constructed with approximately
8,000 cy of cobble and sand (60% cobble, 40% sand) from the Ventura River upstream of the
Santa Ana Bridge. The Surfer's Point beach fill site is located immediately southeast of the
Ventura River mouth. This river is a source of sediment to the littoral cell, especially during wet
Proposed Quantity and Quality of Beach Fill Material
The plan view of the Surfer's Point beach fill site is shown in Figure 3-11. The plan shows a
beach fill length of approximately 2,800 feet beginning just east of the Ventura River mouth and
extends south along Seaside Park. The annual volume of material proposed for this site is
approximately 175,000 cy assuming the material is primarily sand. If the material is primarily
cobble, a smaller quantity of material will be placed on the beach and will be limited to the far
west end of the site (not to Figuroa Street). The annual quantity limit represents the high-end,
worst case for purposes of permitting and environmental review.
