Site prep after a pool comes out — the Pocket's most common sequence
In Pocket-Greenhaven, most site prep starts where a pool removal ends. These pool-heavy 1970s–90s lots are exactly where owners now want an ADU, an addition, or a rebuilt yard, so the pad prep follows the demolition.
The sequence matters and the order saves you money. After the shell is out and the cavity is filled, we rough grade the footprint to the finished floor elevation your architect or the building department sets, coordinate utility trenching for electric, water, and sewer stubs before the pad is closed up, and compact the fill to spec — typically around 95% relative density under a slab per the geotech report. Doing pool removal and pad prep as one continuous scope, with one crew, avoids the classic mistake of grading a pad and then tearing it back open to run a utility line. On the Pocket's clay, it also means the same engineered, lift-compacted fill that closes the old pool becomes the base your ADU sits on — no soft, mismatched layer between the two.
ADU and addition pad prep on the Pocket's curvilinear tract lots
The Pocket's 1970s–90s tract lots are good ADU territory — flat, regular, and deep — but the curvilinear street layout and shared rear fences shape access and staging.
These subdivisions off Pocket Road, Greenhaven Drive, and Riverside Boulevard were laid out on curving streets, with lots that back up to one another and, on the outer blocks, to the levee. That usually means a rear-yard ADU pad has one side-yard route in, so we size equipment to the gate and plan where soil, base rock, and spoils stage before we start. We establish the pad elevation and a drainage slope that carries water away from both the new structure and the existing house, balance cut and fill on site where we can to reduce import and haul-off, and rough-grade an access route the concrete and framing crews can actually use.
- Pad elevation set to the ADU's finished floor elevation, with slope carrying water away from the structure
- Cut-and-fill balanced on site where possible to cut import and haul-off cost
- Access route and staging planned for the single side-yard entry common on curvilinear Pocket lots
- Compaction to the geotech spec so the slab has uniform bearing on clay
Riverfront and levee-adjacent drainage — why grade and runoff matter here
The Pocket sits low on riverfront ground inside a bend of the Sacramento River, behind the levee, on clay that drains slowly and swells when it's wet. That combination makes drainage the make-or-break detail of any pad here. We grade every site so water sheds away from the new structure and ties into the lot's existing drainage rather than collecting against a foundation or pooling in a clay low spot over winter. Where a pad is being raised, we place and compact fill in lifts so it doesn't settle unevenly under a slab. If the finished pad has to sit through the wet season before the slab pours, we plan the erosion control and a temporary drainage path with that timeline in mind. Because parts of the neighborhood are close to the river and the levee, fill and grading near the water can carry additional floodplain or drainage review from the City of Sacramento — so we confirm the parcel's requirements before moving dirt rather than assuming. Erosion control — silt fence or straw wattles and inlet protection — goes in when a graded pad will sit open through the Sacramento rain season, both to meet stormwater rules and to keep your fresh pad from washing.
Permits, compaction, and what a Pocket site prep costs
Site prep in the City of Sacramento can trigger a few permits at once, and the earthwork numbers on a Pocket lot come down to how much has to move and what it takes to hold the grade.
The two things that move a Pocket number most are import fill — clay lots and raised pads often need engineered fill trucked in — and access, since the curvilinear layout and single side-yard gates can force smaller equipment or hand-work. We scope both at the estimate, along with how much cut-and-fill can be balanced on site, and give a real range rather than a phone quote.
- Grading permit: most jurisdictions require one for earthwork above a threshold (often around 50–100 cubic yards) — a typical backyard ADU pad may or may not cross it
- SWRCB Construction General Permit: only triggers on sites disturbing 1 acre or more, so a single Pocket ADU lot is almost always well under it
- Demolition permit: needed if a structure or pool is removed as part of the prep
- Compaction testing / geotech sign-off: typically required for a pad that will carry a slab
- Typical residential ADU site prep in the Sacramento area runs in the mid-four to low-five figures depending on clearing, earthwork, and access
Frequently asked questions
What does site prep include for an ADU in the Pocket?
On a Pocket lot it's usually clearing whatever is left after a pool or structure comes out, rough grading the pad to your finished floor elevation, coordinating utility trenching for electric, water, and sewer stubs, and compacting the fill to the geotech spec. We finish-grade to tolerance for base rock and the slab, and set the drainage slope so water runs away from the new unit and the existing house.
Do I need a grading or stormwater permit for a Pocket ADU pad?
A grading permit depends on how much earth moves — most jurisdictions set a threshold around 50–100 cubic yards, and a small backyard pad may or may not cross it. The state SWRCB Construction General Permit only kicks in on sites disturbing an acre or more, so a single Pocket ADU lot is almost always well under it. We confirm what the City of Sacramento requires for your parcel before work starts.
How does being near the river and levee affect my pad?
The Pocket sits low behind the Sacramento River levee on slow-draining clay, so pad elevation and drainage carry more weight here than on higher ground. We set the grade to shed water away from the structure and into existing drainage, and compact any raised fill in lifts so it doesn't settle. Where a parcel is close to the river or levee, added city floodplain or drainage review can apply, and we check that up front.
Can you prep the pad right after removing my pool?
Yes, and doing both as one scope is the efficient way to handle a Pocket lot. The same engineered, lift-compacted fill that closes the old pool cavity becomes the base for the ADU pad, so there's no soft, mismatched layer and no second mobilization. It also avoids grading a pad and then reopening it to run a utility line.
What does site prep cost in Pocket-Greenhaven?
Typical residential ADU site prep in the Sacramento area runs in the mid-four to low-five figures, driven mostly by how much clearing and earthwork the lot needs, how much engineered import fill the clay requires, and access. On the Pocket's curvilinear lots the single side-yard gate can force smaller equipment, which we scope at the estimate before giving a firm range.
