Check that the drawings describe the same starting point
Use the same site information and scale for both options. Match the existing structures, retained planting, boundaries and access points. Label any assumption that differs. A plan that removes a patio cannot be fairly compared with one that preserves it as though the surrounding work were identical.
Separate a concept still awaiting site review from an option the design team has assessed. Pasadena’s single-family submittal requirements identify the site and structural information needed for its review; a polished rendering alone does not establish that either option can proceed.
Describe what each option changes in the yard
For each plan, write a short account of the water area, seating location, retained open area and everyday routes. Use the same headings for both. Mark a meaningful difference directly on the drawing rather than relying on labels such as “resort” or “family design.”
As an illustrative comparison, one option might keep the existing patio and provide a smaller water area. Another might alter the patio to accommodate the preferred pool shape. The decision concerns the resulting spaces and work, not a general rule that a larger pool is the better choice.
Separate the base layout from optional features
Compare the basic layouts before adding every desired feature. Then show each proposed spa, ledge or water feature as a named option and identify the space it changes. This makes it easier to see whether you prefer the arrangement itself or the accessories shown in its rendering.
Do not blend attractive parts of separate plans into a final choice without another design review. Moving a spa or retaining a different edge creates a revised option whose relationships still need checking. Record that revised option as a new version.
Compare changed work and unresolved questions
For each option, identify removal, new surrounding work, equipment changes and restoration that are included or excluded. Keep a proposal price tied to that version and scope. An option with fewer visible features can still involve different site work.
Make a short open-question list for each alternative. An unresolved level change, unknown retained structure or missing product selection belongs on that list. Do not fill the gap with an assumed price, approval date or performance promise.
Choose for a stated reason and keep the record
Name the priority that decided the comparison: preserving a particular yard area, a preferred view or a simpler route from the house, for example. Record what you are giving up as well. This helps prevent discarded features from quietly returning in later conversations.
Keep the chosen dated drawing, accepted options and remaining questions with the proposal. CSLB recommends retaining project documents and written details. The layout guide helps prepare the initial arrangement; this comparison record explains why one defined option was selected.
