Petition to Protect Altadena’s Neighborhood Character and Ensure Safe, Responsible Development at 369 E Altadena Drive (APN 5841-021-018).

We, the undersigned residents and community members of Altadena and surrounding areas, are calling for full transparency, rigorous safety review, and responsible scaling of the proposed 9-unit subdivision at 369 E Altadena Drive, Altadena, CA 91001 (APN: 5841-021-018).

While we support thoughtful housing development and post-fire recovery efforts, we strongly oppose unchecked subdivision that compromises public safety, overwhelms infrastructure, and permanently alters the historic character of Altadena’s residential neighborhoods.

Issue #1. Fire Safety and Emergency Access Concerns:
Altadena is a designated Very High Fire Hazard Severity Zone. In the wake of recent devastating wildfires, emergency access, evacuation capacity, and fire response time must be the highest priority.

A 9-unit subdivision on a single residential parcel raises serious concerns, including:

Adequate fire truck access and turnaround space
Narrow internal driveways or shared access points
Increased evacuation congestion on E Altadena Drive
Water pressure and hydrant capacity for multi-unit density
We request a full, independent review by the Los Angeles County Fire Department to ensure that the proposed project does not increase wildfire risk or hinder emergency response.

 
2. Infrastructure Capacity and Utility Strain
We are concerned that existing infrastructure may not support intensified density on this parcel, including:

Sewer system capacity
Water supply and fire flow adequacy
Electrical grid limitations during peak demand
Stormwater drainage and post-fire runoff risks
We request that no approval be granted without verified “will-serve” letters from all utility providers and a publicly reviewed infrastructure impact analysis.

3. Over-Intensification of a Historic Residential Neighborhood
Altadena is known for its historic, low-density residential character, mature tree canopy, and single-family neighborhood scale.

A 9-unit subdivision on a single lot would:

Significantly increase population density on a historically single-family parcel
Alter the scale and rhythm of the surrounding neighborhood
Increase traffic, parking pressure, and noise in a narrow residential corridor
Set a precedent for similar over-subdivision throughout Altadena
We believe development should respect the historic fabric of the community, not replace it with high-density infill that is incompatible with the surrounding area.

 
4. Environmental and Site-Specific Concerns
This property and the surrounding area may also face:

Post-fire erosion and debris flow risks
Soil stability and grading challenges
Loss of mature trees and green canopy
Increased impervious surface area and runoff
We request a full geotechnical and environmental review prior to any approval.

 
5. Request for Action
We respectfully urge Los Angeles County to:

Conduct a full public safety and infrastructure review of the proposed subdivision
Require transparency of all site plans, maps, and technical reports
Ensure compliance with fire safety and evacuation standards
Consider reducing the scale of the project to a level compatible with neighborhood conditions
Engage the local community before approving any final entitlements
 
Closing Statement
We are not opposed to rebuilding or thoughtful development in Altadena. However, we believe that post-disaster recovery must prioritize safety, infrastructure capacity, and preservation of community character.

A 9-unit subdivision on this parcel raises serious questions that must be fully addressed before any approval is granted.

We urge decision-makers to proceed cautiously, transparently, and in the best interest of long-term community safety.

The proposal to subdivide a single residential parcel into a 9-unit subdivision in Altadena, CA is a matter that hits close to home. This neighborhood is not just a place; it's a community where families have grown, friendships have flourished, and memories have been etched into the very streets we walk. To see a single parcel potentially transform into a dense 9-unit housing complex is alarming and tugs at the heart of what makes our community unique.  

Altadena is renowned for its rich history and the harmonious blend of nature and residential living. The introduction of a subdivision of this magnitude threatens to disrupt the character and serenity that residents cherish. This drastic change would inevitably lead to increased traffic, noise pollution, and a strain on local resources such as water, sewage, and emergency services, all of which are already operating at their limits. According to the US Census Bureau, Altadena has maintained a steady growth rate, yet planning reports indicate that infrastructure improvements are lagging, raising red flags about accommodating such a development.

Furthermore, environmental concerns cannot be overstated. The subdivision threatens to encroach on open spaces that are home to local wildlife, upsetting the balance of our local ecosystem. With studies by the California Department of Fish and Wildlife suggesting significant ecological impact from increased urban developments, these plans could irreparably damage habitats.

The most troubling aspect is the impact on the sense of community. Numerous studies highlight how dramatic changes in neighborhood density can lead to reduced social cohesion and a weakening of community ties, something that Altadena's residents rely on in times of joy and particularly in times of adversity. The proposed subdivision might provide short-term housing solutions, but at what long-term cost to the community fabric?

We urge local officials to reconsider this subdivision proposal in Altadena. We must prioritize thoughtful, sustainable development that respects the cultural and environmental heritage of our community and keeps the well-being of our current residents at the forefront. 

Signed,

Concerned Residents of Altadena and Surrounding Communities.
