SUBJECT: AUTHORIZATION TO SOLICIT CONSTRUCTION BIDS FOR THE

DOWNEY GRAMMAR SCHOOL ARCH REPAIR PROJECT

EXECUTIVE SUMMARY

The City Council will consider authorizing the solicitation of construction bids for the Downey Grammar School Arch Repair Project. The proposed project will complete concrete repairs to the Downey Grammar School Arch located on Civic Center Drive between Brookshire Avenue and 3rd Street. The project also includes the installation of a roof structure to protect the Arch from further weathering.

RECOMMENDATION

That the City Council:

Approve the plans and specifications, and authorize the solicitation of construction bids, for the Downey Grammar School Arch Repair Project.

BACKGROUND
As part of a broader initiative to preserve Downey’s historic resources, the City of Downey retained Architectural Resources Group, Inc. (ARG) to conduct a condition assessment and provide treatment recommendations for the historic Grammar School Arch (Arch) located on Civic Center Drive. Originally constructed in 1916, the Arch served as the main entrance to the former Downey Grammar School at 8425 Second Street. The school was designed by prominent architect John C. Austin, known for designing the Los Angeles City Hall and the Griffith Park Observatory. After the City of Downey was incorporated in 1957, the building transitioned into serving as the first City Hall. In 1984, the Arch was relocated to its current location behind the new City Hall and was restored based on a schematic design by architect Martin Weil. Restoration at that time included setting the arch on a two- to three-foot foundation, repainting, re-stuccoing, and inserting iron beams for structural stability. Though plans for a red-tile roof were included in the initial restoration effort, the roof was never installed or was subsequently removed. A bronze donor plaque was also added to the interior wall of the arch.

ARG conducted a non-destructive visual survey on November 5, 2024, inspecting the structure from the ground and via ladder, and supplemented this assessment with client- provided photographs from October 2024. Using a sounding hammer, ARG tested accessible stucco surfaces to identify areas of delamination, cracks, spalling, and paint failure. Based on this survey, ARG developed treatment recommendations aligned with the Secretary of the Interior’s Standards for the Treatment of Historic Properties and the American Institute for Conservation’s Code of Ethics. These recommendations emphasize the importance of preserving the Arch’s original materials and form wherever possible. The Standards for Preservation advise retaining historic fabric, while the Standards for Rehabilitation allow for greater flexibility in replacing significantly deteriorated or missing features.

Due to the historical significance of the Grammar School Arch, City staff from the Community Development Department (CDD) has kept the Downey Conservancy informed of their efforts regarding the Grammar School Arch. The Conservancy has expressed its appreciation and support for staff’s commitment to restoring the Arch in accordance with recognized historic preservation standards.

ANALYSIS

CD and Public Work have closely coordinated to develop the bid documents, and plans and specifications for the Downey Grammar School Arch Repair Project on Civic Center Drive. Design drawings have been developed to preserve this historic 1916 arch while correcting long-standing deterioration. The design work was completed through the consultant contract for the General Plan update.

Work will begin with gentle, low-pressure washing of all concrete and stucco surfaces to remove loose material before any repairs or coatings are applied. After cleaning, the crew will sound the façade, which is a process of assessing stucco for poorly-adhered material by tapping and listening for any hollow sounds. After this is complete, the crew will rout and patch cracks, excise unsound stucco or prior non-compatible patches, and replace spalled areas with a cementitious repair mortar; where reinforcement is badly corroded, it will be cut out and replaced with new stainless-steel bars to extend service life. Once the substrate is restored, the entire arch will be primed and painted to match its historic finish. The temporary plywood roof will be removed and a new roofing assembly will be installed to protect from further weathering. All work will follow the mock-up and review procedures required for historic resources.

Construction is scheduled to begin in October 2025, with completion anticipated by December 2025.

This Project is categorically exempt from the provisions of the California Environmental Quality Act (CEQA) under Section 15301(c), Existing Facilities.

FISCAL IMPACT

There is no fiscal impact associated with the authorization to solicit bids for the project.

Historical restoration work is less common and more difficult to estimate. However, staff assumes this work will require a minimum of $100,000 for specialty contractors and inspectors to complete the restoration. A request to appropriate funds will be presented to Council to complete the project when staff returns for consideration of the contract award.
