Stencil the unmarked storm drains of Grand Terrace before the first fall storm

Grand Terrace drains fall toward the Santa Ana River, and its residential inlets are mostly unmarked. First-flush storms carry a summer's worth of oil and litter straight into the river system. Painted no-dumping stencils at each inlet are a proven low-cost habit-changer. Standard: EPA NPDES MS4 outreach best practice; Santa Ana Regional Water Board — SDG 6. Proof: Photos of each stenciled drain plus a count Method (EPA NPDES MS4 outreach best practice; Santa Ana Regional Water Board — SDG 6.): 1. Map unmarked or faded inlets on the assigned residential blocks. 2. Sweep each curb face clean. 3. Paint the no-dumping stencil beside each inlet with exterior paint. 4. Bag any litter sitting on the grates. 5. Photograph every stenciled drain with GPS and date and log the count. Done when: Photos of each stenciled drain plus a count

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 30–75 minutes. Method of record: EPA green-infrastructure inspection (bioretention / bioswale / permeable pavement function + maintenance)

Bring

• measuring tape
• GPS phone
• camera
• trowel / probe
• data sheet
• gloves

Steps

1. 1. Locate the GI asset; record GPS; identify the type (rain garden / bioswale / permeable pavement / tree filter).
2. 2. Photograph the asset, its inlet, and its outlet/overflow.
3. 3. Check the inlet and outlet for blockage (sediment, trash, mulch) and note whether flow can enter/leave freely.
4. 4. Check for standing water and estimate whether it drains within the design window (typically <24-48h after rain); probe media if dry.
5. 5. Assess vegetation/media condition and estimate sediment/trash accumulation depth.
6. 6. Note erosion, bypass, or structural damage and list the maintenance needed.
7. 7. Enter asset type, condition, inlet/outlet status, drainage observation, sediment level, maintenance needs, GPS, photos; sign.

If it does not match the plan

• Standing water persists > 48h after rain -> flag failed infiltration (clogged media) for rehab.
• Inlet or outlet blocked -> flag for cleaning; the asset isn't capturing runoff.
• Erosion, undercutting, or flow bypassing the asset -> flag for repair.
• Documentation only — no digging out media or altering structures.

What counts as done

• Asset type + overall condition recorded
• Inlet + outlet clear/blocked status recorded
• Standing-water / infiltration observation recorded
• Sediment/trash level + maintenance recommendations + GPS + photos

Proof is measured against these, not judged by taste.
