Final Contract costs with Zimprich Engineering totaled $429,712.69.
The remaining work, specifically the planting of the Panorama Promode slope, was not included in Zimprich Engineering’s original contract.

Background and Analysis:
On February 4, 2024, Governor Gavin Newsom proclaimed a State of Emergency for eight counties in Southern California, including Los Angeles County, as a series of winter storms began impacting much of the State with high winds, damaging rain, and heavy snowfall. California Government Code 8630, et. Seq., and Signal Hill Municipal Code (SHMC), Chapter 2, Section 2.76.060, provides the City Manager, as Director of Emergency Services, the authority to proclaim the existence of a local emergency if the City Council is not in session, which was proclaimed within 10 days of the event. The City Council must then ratify the proclamation within seven days, or the proclamation shall have no further force or effect.
On February 7, 2024, the City Manager, acting as the Director of Emergency Services, signed a Proclamation of a Local Emergency due to the February 2024 winter storm activity. On February 13, 2024, the City Council adopted a resolution ratifying the proclamation of the existence of a local emergency. Government Code Section 8630 requires the City Council to renew a local emergency for the duration of the emergency. At the same meeting, the City Council adopted a resolution amending the adopted budget and authorizing budget appropriations for emergency repairs resulting from the 2024 winter storm damage in the amount of $800,000. To remain in effect, the City Council must renew the need for the local emergency every 60 days until the City Council terminates the local emergency. The latest continuance of the proclamation of the existence of the local emergency was approved at the August 27th Council meeting.
At the February 27, 2024, the City Council meeting, extended the proclamation of a local emergency and adopted a resolution. Additionally, the City Council authorized the City Manager or his designee, pursuant to Public Contract Code Sections 20168 and 22050, to enter into an emergency public works contract with Zimprich Engineering, for a not-to-exceed amount of $431,910. This contract was for the emergency repairs related to the Panorama Promenade and the slope at Molino Avenue and 20th.
Panorama Promenade Trail Repairs
The Panorama Promenade experienced significant slope failures in two localized areas following the February 6, 2024, rainstorm activity, resulting in the closure of the walking trail. Repair work completed by Zimprich Engineering consisted of backfilling and compacting of soil at the four slope locations, which demonstrated significant failure. The site stabilization along the 1600 lineal feat of trail, and the installation of a post and batter soil retaining system, was completed in early April. The Geotechnical Engineer and the Public Works Director conducted several site visits and performed inspections. The trail was re-opened to the public on April 30, 2024.
Molino Avenue and 20th Street Slope Repairs
The Molino Avenue and 20th Street intersections experienced similar slope failure and erosion, resulting in a damaged hillside; the failure also created unsafe conditions that could have worsened left unattended. Zimprich Engineering began repair work in mid-February by installing erosion control devices such as plastic sheeting and sandbags to stabilize the site. Construction of the retaining wall commenced on April 2, 2024. The removal of an unforeseen 24” thick subterranean concrete slab and an abandoned 8” oil pipeline that belonged to Oil Operators Incorporated, both of which were found running parallel and in conflict with the proposed retaining wall footing, delayed the project by three to four weeks. However, work on the construction of the retaining wall continued after the contract resolved the substructure conflicts. Zimprich Engineering completed the slope stabilization and retaining wall installation on July 29, 2024.
The final contract amount for the immediate repair work at Panorama Promenade Trail and the slope at Molino Avenue and 20th Street was $429,712.69. Zimprich Engineering successfully completed the repairs for both locations to the satisfaction of the Public Works Department and in accordance with the project scope. Staff recommends the City Council adopt a resolution declaring final acceptance of the work performed by Zimprich Engineering.
The future planting effort at Panorama Promenade Trail will utilize the remaining budget for both projects, with an estimated total of $300,000. Once the contractor is selected, staff will return to the City Council for contract approval. This planting scope is currently in design and will be advertised, with planting commencing in late fall 2024.
