Identify the tree and the actual observed condition
Downey’s Maintenance Division describes tree, landscape and irrigation work on public grounds, streetscapes, medians and parkways. Its Trees, Parks and Grounds Maintenance page also links a separate House Alert resource about sewer house laterals and tree roots. The page is a starting point for routing a site question.
Show the tree position and the affected frontage clearly, then record the observed drain or ground condition in a different entry. Include dates and changes over time. A slow drain, visible surface change and nearby tree are observations; they should not be turned into a confirmed root diagnosis.
Use the house-lateral resource as a separate question
Use the City-linked house-lateral resource to frame a separate enquiry about the issue. Ask the appropriate City contact or private professional which assessment is relevant to the actual location. This guide does not repeat procedures from the linked brochure or determine ownership and repair responsibility.
Retain any City report reference and assessment findings with the proposed work. Identify what you want reviewed, which surrounding surfaces should remain and what finish is expected afterward. Keep a tree enquiry, a plumbing assessment and a surface repair separately defined until the relevant parties confirm their roles and accepted tasks.
Where does Downey link house-lateral and tree-root information?
The Trees, Parks and Grounds Maintenance page links it under House Alert Tips. Use that City resource to identify the relevant question; this guide does not reproduce the linked brochure’s procedures.
Does a nearby City tree establish the cause of a drain problem?
No. Record the tree location and actual symptoms separately and obtain appropriate assessment. A nearby tree alone does not identify the cause, ownership or repair responsibility for the drain concern.

For a rented home, confirm who can authorize alterations. In a shared building, ask about access and work rules. A citywide construction period does not establish the age, condition or safety requirements of an individual home; check the property records and the specific project.
