Proposed engineering standards
The proposal's consistent recommendation across the technical papers: regulate outcomes — safe pedestrian passage, certified electrical equipment, responsible temporary use of the right-of-way — using performance standards matched to a nightly residential charging scenario, not requirements derived from permanent infrastructure or commercial operations.
1. Cable protection — temporary removable protector
Evaluated as a temporary pedestrian facility, an approved device must meet performance goals, not a fixed product spec:
| Criterion | Requirement |
|---|---|
| Stability | Lies flat; does not shift, rock, or migrate under pedestrian traffic. |
| Slip resistance | Textured walking surface effective wet and dry. |
| Visibility (day) | High-contrast (safety yellow or equivalent), detectable in daylight and under street lighting. |
| Visibility (night) | Retroreflective marking along the leading edges, plus illumination of the crossing where street lighting is poor — a porch or solar fixture covering the cable route is sufficient. Added in response to the single night-time incident reported in the 311 record. |
| Traversability | Low profile with beveled, gradual edges passable by wheelchairs, strollers, and carts. |
| Cable containment | Fully encloses the cord; rated for pedestrian loading. |
| Deployment | Placed perpendicular to the path of travel where feasible; present only while actively charging; stored on private property otherwise. |
What the standard is not: a permanent ADA curb ramp. Permanent-infrastructure geometry is the wrong test for a device that exists on the sidewalk a few hours a week — the ADA, VDOT, and Alexandria's own MOT policy all evaluate temporary facilities under a practicability standard instead.
The removable protector is the baseline, not the ceiling. Where a household wants a permanent crossing, a recessed cable channel cut flush into the sidewalk removes the surface ramp entirely; the crossing-options analysis compares ramps, channels, overhead arms, and flat cables and proposes one standard channel detail for ordinary concrete sidewalk.
2. Charging equipment — certified EVSE
Standard
Certified EVSE (e.g., UL 2594 / UL 2231 listed, SAE J1772 coupler), installed in accordance with the National Electrical Code (Article 625) and manufacturer instructions, with ground-fault protection. No distinction between Level 1 and Level 2.
Rationale in Electrical Safety & Charging Level: the safety layers live in the certified equipment, not the voltage — and Level 2's shorter sessions reduce the hours a cable occupies the sidewalk. Improvised extension-cord arrangements are excluded categorically.
3. Insurance — risk-based, residential tier
Standard
Proof of homeowners or renters personal liability insurance applicable to the permitted crossing; if the City states a minimum, $500,000 per occurrence — the City's existing residential-encroachment limit. Avoid commercial insurance standards for a residential use.
Rationale in Liability Insurance: Alexandria's own encroachment guidance is tiered by risk, and this use is analogous to the residential tier, not to parklets or outdoor dining.
Operating rules that tie it together
- Temporary use only — cable and protector removed when not actively charging; no storage in the right-of-way.
- Homeowner responsible for equipment condition and maintenance.
- No reserved parking; no signage or cones.
- Immediate removal for snow, ice, construction, emergencies, or City direction.
- Revocable, site-specific, non-transferable permit; inspection before effect; reinspection on complaint.
Future research & possible additions
Items identified for follow-on work as the proposal matures:
- Trip-and-fall claims history involving commercial cable protectors; insurance claim data.
- Accessibility and wheelchair traversal testing of candidate devices.
- Photos and engineering drawings of approved products.
- Prototype permit application and inspection checklist.
- Draft ordinance text and broader economic analysis.
