Why does a rowhouse lot need a plan?
A rowhouse lot has little room for error. A unit that is one foot out of line can block a gate, a hydrant or a front door, and the plan avoids that before the truck arrives.
The plan is short. It is a sketch of the frontage and the alley with the spot marked, a note of the gate width and the route, and a photo of the chosen place. It takes a few minutes to make from a phone, and it saves a return trip or a moved unit on the day. On a block where the neighbours share the alley, the plan also shows the other households that the unit is there.
A plan also helps the permit. A unit at the curb is shown on the public space application, and the plan is what the site drawing is based on.
How wide must a side gap be?
The gap must take the unit's width, the door swing and a person standing beside the unit. The exact clearance depends on the unit and the lot, and it is checked on site.
A standard unit needs enough room for its door to open outward and for the user to pass it without squeezing against a wall. In many District side gaps the room is tight, and the placement may be better in the rear alley or at the curb. The gap is also a path for the crew, so its width matters for the people who walk through it every day.
Where the gap is too narrow, the provider will suggest the alley or the curb and will not force the unit into a space that cannot take it.
How does the truck reach an alley?
The truck needs a route into the alley and room to stop, and the gate must be wide enough for the unit to be carried through. Where the alley is too narrow, the unit is placed at the front.
An alley in Dupont Circle or Capitol Hill is often a few metres wide, with garages, bins and parked cars along one side. The truck can often stop at the mouth of the alley and the unit can be rolled in on a dolly, but this needs a gate that opens fully and a clear route. A gate that is locked or blocked by a bin needs to be checked before the booking.
The provider checks the route on the day. Where it cannot be made, the unit is placed at the nearest workable spot and the change is agreed with the owner or the site lead before it is set down.
What about the neighbours and the public space?
The unit is set out so that neighbours can reach their own doors, gates and bins, and any part of the unit on public space is covered by the permit for that space.
A rowhouse unit affects the neighbours even when it is on the owner's lot. Their access to a shared alley, their bin collection and their parking can all be changed by a unit on the wrong spot. The plan notes the neighbours' access, and the site lead is asked to tell them when the unit is coming.
A unit that stands on the public curb or sidewalk needs the District's public space permit, and it has to be shown on the site plan with its dimensions. The permit is filed through the District Department of Transportation's online system, and it is a separate step from the event or construction permit.
How do the seasons change a rowhouse placement?
Wet springs soften the ground in alleys and side gaps, and summer heat means the unit needs more frequent cleaning. The pad, the anchoring and the servicing interval are checked for each season.
A pad set on firm ground in March can sink or tilt after a wet April. The servicing visit checks the level, and a unit that has moved is reset before the door starts to bind. In summer the unit fills faster in hot weather, and the servicing interval is shortened to match. Neither change is a fixed date, and both are checked at each visit.
