The Initial Threat (Archive)

A Threat to Our Foothills:

On October 11, 2022 it was announced that Nuccio’s Nursery on Chaney Trail will wind down operations in the next two to three years and that Polytechnic School (Poly) will take ‘stewardship’ of the 78-acre property in the northern Altadena foothills.

The announcement was made in a joint letter from the Nuccio family and the private Pasadena school and in a letter issued to the Poly community by the school. After nearly 90 years of operations, the world-famous camellia and azalea nursery will be closed. Polytechnic School is seeking to purchase the Nuccio parcels, comprising 1.44% of Altadena's total land area.

In April 2024, Poly announced their plans to build ‘Poly Fields,’ an athletics campus/sports complex on the site of the current nursery.  The campus would include a football/soccer/athletics stadium, a baseball stadium, and six tennis courts — each with spectator seating.  The proposal also includes a training facility, a student fitness center, a wellness center, a coaches building, batting cages, various equipment storage buildings, and a lounge.  Poly Fields will also include outdoor lighting for night events, amplified sound, and a 208-vehicle underground parking structure.  The closed campus would be surrounded by walls and fencing, including a 500-square-foot “security lodge.”

AltadenaWILD's position is that even if development is limited to the nursery footprint, the proposed sports complex will irrevocably change the character of the remaining 65 acres and decrease its value for conservation and enjoyment. Hundreds of additional visitors, coupled with high-intensity lighting and sound systems, will negatively impact native wildlife and their migration corridors.

If Los Angeles County approves the proposed Polytechnic School sports complex on Chaney Trail, these developments will increase the risks to public safety and dramatically change the character of a semi-rural area adjacent to the Angeles National Forest/San Gabriel Mountains National Monument.

Our petition opposing the development has over 7000 signatures and counting.

The petition will be presented to key entities involved in the Los Angeles County review/decision process, including the: Altadena Town Council, the L.A. County Department of Regional Planning, and the L.A. County Regional Planning Commission.
