Who can help me meet Somerville's Green Score?
American Elm Landscape handles Green Score compliance from design through approved permit and finished install. Most homeowners hit Green Score for the first time when they go to replace a driveway or build a patio, and quickly find out it is a landscape-performance standard with a scorecard, a stamped-drawing requirement, and a city review. We do this work every season across Somerville — so instead of hiring a designer, a separate permit consultant, and an installer who all point at each other, you get one team and one phone number.
What we handle — the whole compliance path
We take a Somerville Green Score project from a rough idea to an approved, built, code-compliant landscape. That includes:
- Site evaluation & scoring layout — we measure the lot and design a landscape that clears your district's minimum (0.35 for most residential lots).
- Official Green Scorecard — we complete the City of Somerville scorecard, balancing permeable paving, plantings, trees, and de-paving bonuses.
- Stamped drawings & documentation — MA-registered landscape architect plans plus the section details, cut sheets, and infiltration test results the city wants.
- Permit submittal — we submit to Planning & Zoning or Inspectional Services and answer the city's review comments.
- The build — permeable driveways and patios, native plantings, rain gardens, and walls, installed to the spec that was actually scored.
How much does Green Score compliance cost?
For most residential projects the compliance work is folded into the driveway, patio, or landscape you are already building — there is rarely a separate "Green Score fee." A permeable paver installation costs more than plain asphalt because of the engineered stone reservoir and the documentation, but it satisfies the stormwater rule and earns Green Score at the same time, so you are buying two things with one install. We give a fixed quote after we measure the lot and run your scorecard, so you see the real number before you commit.
What earns the most points on a tight Somerville lot?
On a small lot, the two biggest levers are one approved large native street-facing shade tree and making your patio or driveway permeable over torn-out asphalt. A single native, high-value, frontage shade tree can credit roughly 450 weighted square feet — often about three-quarters of a passing score by itself — and it sits in the front strip, so it doesn't eat into your usable back yard. Permeable paving stacks paving credit with a de-paving bonus. We walk through the full point system, with a worked 0.35 example, in our Somerville Green Score & permeable paving guide.
Why a design-build firm beats hiring the pieces separately
Green Score problems almost always happen at the seams between companies. A designer draws a plan, the installer says "we can't build that," and the homeowner pays twice — or the scorecard says one thing and the finished job says another, and the city sends a revise-and-resubmit. Because we survey, score, document, permit, and build as one job, the plan that gets approved is the plan that gets installed. That is the difference between clearing review on the first pass and scrambling at permit time.
Why the install decides whether it keeps scoring
A permeable system only keeps its Green Score credit if it keeps infiltrating — and that comes down to the install. The common failures we're called to fix are all workmanship: sand instead of #8/#9 angular stone in the joints (seals the surface in a season), wrong subgrade compaction, no edge restraints for New England freeze-thaw, and no sediment-management plan. Built to spec, a permeable system drains and scores for decades.
A Green Score job is half hardscape, half drainage engineering. Treat it like the first half and it fails review — or fails in February.

Who can help me meet Somerville's Green Score?
American Elm Landscape — a Somerville design-build firm since 1989 — handles it end to end: scoring layout, the official Green Scorecard, stamped documentation, the city permit submittal, and the permeable install that earns the points. One team, one number: (781) 859-5304.
Do you handle the paperwork and the city permit?
Yes — we complete the scorecard, assemble the stamped section detail, cut sheets, and infiltration tests, and submit to Somerville Planning & Zoning or Inspectional Services. Because we also build the job, the paperwork matches the install, which cuts down revise-and-resubmit loops.
How much does it cost?
For most homes the compliance work is built into the driveway, patio, or landscape you're already doing — a permeable install costs more than plain asphalt but satisfies the stormwater rule and earns Green Score together. You get a fixed quote after we measure and score your lot.
What earns the most points?
One approved large native street-facing shade tree, plus making the patio or driveway permeable over torn-out asphalt. A single good shade tree often earns roughly three-quarters of a passing 0.35 score.
How long does approval take?
It varies with the city's queue, but getting the documentation right up front is what avoids the long delays. We build the submittal to aim for approval on the first pass.

Green Score requirements are set by the City of Somerville (Green Score Guide; Zoning Ordinance Section 10.4) and can change — we confirm current figures against the city's official scorecard before every submittal.
