1. Project Overview & Scope of Work We are seeking a licensed Structural Engineer (SE) to provide structural calculations, engineering details, and wet-stamped construction drawings suitable for submission to the City of San Clemente Building and Planning Divisions. The project encompasses a residential backyard terrace extension with the following specifications: Elevated Suspended Concrete Deck Platform: Dimensions: 30 feet wide by 12 feet deep (360 sq. ft.) at a finished elevation of 6 feet above local grade. Structural Slab: 4,000 PSI structural concrete mix poured over 1.5-inch 18/20-gauge galvanized corrugated steel B-decking, reinforced with a continuous deformed rebar grid mat, engineered for a 50 PSF residential live load plus dead loads. Hybrid/Split Foundation & Support System: Left & Center Support: Existing drawings verify that the masonry walls on the left-hand side (excluding the front wall of the spa equipment enclosure) are active, fully filled, and reinforced retaining walls. The design will utilize structural epoxy-anchored rebar dowels to tie the left side of the deck ledger/framing into these verified active retaining walls. Right-Hand Side Support: Bypasses earth retention on the sloping 21-degree terrain via a deep pier and post-and-beam system (utilizing Sonotube concrete piers, 6x6 pressure-treated structural posts, and engineered multi-ply 2x12 or Parallam PSL header beams). Upper Slope Transition (Stepped Retaining & Planter Walls): A dual-tier stepped arrangement spanning 5–6 feet wide across the center section to square off an irregular hill profile. Lower Tier: A 2-foot structural/CMU planter front wall forming a 24-inch wide edge planter, finished with a 12-inch wide concrete seating coping. Upper Tier: A 2-to-3-foot light retaining wall positioned directly behind the planter beneath the rising fence line to create a level terraced planting bed. Front Elevation & Drainage Integration: A 30-foot continuous front elevation wrapping the existing spa structure and a 21-foot non-bearing cosmetic screen wall extension. Specifications for a minor 2-foot toe cut backed by a 12-inch French drain void (geotextile fabric, 4-inch perforated PVC pipe, and clean 3/4-inch drain rock) to eliminate lateral soil pressure against the cosmetic facade. Backyard Property Line Glass Fence: Non-structural 42-inch glass fence assembly replacing an old vinyl fence along the edge of the slope entirely within property lines (layout and material cut-sheet integration). 2. Required Deliverables Structural Calculation Package: Complete engineering calculations covering dead/live loads, seismic/wind criteria, deck slab design, anchor dowel sizing, pier depths, header sizing, and retaining wall stability. Stamped Construction Drawings (Plan Set): Ready for city permit submittal, including: Foundation and framing plan. Connection details for the epoxy dowels into the existing active masonry walls. Details for the right-hand deep piers and post-and-beam framing. Planter and light retaining wall reinforcement details. Drainage and waterproofing integration details. Revisions/Plan Check Support: Addressing initial structural review comments from the City of San Clemente Building Department if required. 3. Available Documentation for Engineer Existing architectural/structural drawings (confirming active filled retaining wall construction on the left). Site layout measurements and slope topography data (21-degree uniform slope, max 8.06 ft drop). Please see attached

Hello there! This project is right in my wheelhouse, and I’d be glad to help move it toward permit-ready drawings. I understand the mix of suspended concrete deck, split foundation support, retaining/planter walls, and drainage coordination, and I’d handle it with the care a licensed structural package needs. I’d start by reviewing the existing drawings, site slope data, and the attached plans to confirm load paths, wall conditions, and support points. Then I’d prepare the structural calculations for the deck slab, dowels, piers, beams, planter walls, and lateral stability, followed by a clear stamped plan set for City of San Clemente submittal. The key pieces here are the epoxy anchor design into the active masonry walls, pier sizing on the sloped side, and making sure drainage details protect the walls and cosmetic facade. I’d keep those details tight so the city review is smoother and fewer comments come back. Best regards.

Hi This project involves the detailed analysis and design for a suspended concrete deck platform, a challenging and engaging task. The primary technical challenge lies in ensuring the hybrid/split foundation supports the deck, given the terrain and active masonry walls. This requires precise integration of structural epoxy-anchored rebar dowels with the existing walls and a calculated pier and beam system on the slope. I've engineered complex foundation systems over variable grades, similar to a recent multi-level terrace project. My expertise in creating permit-ready, stamped construction drawings aligns with your needs. The detailed specs, like drainage integration to manage soil pressure, show your thoughtful planning. I'm ready to help make this extension both secure and visually appealing. Let's connect so I can show you my approach for a smooth approval process. Thanks, David
