Describe the feature before choosing a standard detail
Corona’s Construction Standards page separates garden/block-wall and retaining-wall resources. It also lists patio-cover, balcony, ledger-attachment and sample site-plan resources; this guide does not evaluate the technical details within those PDFs. City resource.
Use those categories to frame the question, not to choose a structural solution yourself. Say what the feature does, where it sits and what would change. If it appears to retain soil or connect to the building, make that relationship visible in the inquiry.
Show the site and attachment in the inquiry
Prepare a wide view of the setting and details of the affected area, with approximate dimensions clearly identified. Show nearby grade, structures and the connection to the house where relevant. Mark what is existing and what is proposed.
Ask the city and the person assessing the work which resource or professional assessment fits the actual feature. A standard’s title cannot establish that its design applies to your site. Keep structural questions separate from cosmetic finishing, and do not let a broad outdoor-maintenance label conceal a change in support or attachment.
Project questions
Why should I distinguish a garden wall from a retaining feature in Corona?
The city lists separate resources for those functions. Explain whether the feature retains soil and ask which assessment or detail applies; do not infer a suitable design merely from its appearance.
What should a Corona patio-cover inquiry show besides its size?
Show the connection to the house, support locations, site setting and the proposed change. Those details help explain the question, while the city and appropriate assessor determine the required information.

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.
