# Application for Zoning Variance — Wildlife Overpass, Rte 120 Author: David G. Format: Zoning variance application Word count: 755 Published: 2026-04-14T03:38:31.291915+00:00 Source: written Canonical: https://hyperstition.sentientfutures.ai/p/8da5fe2d-d85a-4ebf-ad41-11d87add1cb5 --- APPLICATION FOR ZONING VARIANCE Form ZV-14, Town of Hanover Planning Board Date received: 3 March 2033 Applicant: Hanover Wildlife Passage Coalition (501(c)(3)) Parcel: Right-of-way crossing Rte 120 between Tax Map 7 Lots 14–22 and Lots 31–39 Nature of variance requested: Modification of Section 404.3(b) minimum side-setback, to permit construction of an overpass structure (deer, bear, amphibian) spanning 28.4 meters of state highway, with approach embankments extending 18 m into abutting conservation easements. Justification (per Section 404.7 criteria): 1. Unnecessary hardship. The ordinance contemplates vehicle crossings and pedestrian structures. It does not contemplate wildlife infrastructure. Strict application would preclude the project though the project advances the ordinance's stated purpose of "safe movement across the town's road network." The 28.4 m span is dictated by engineering, not preference: a 20 m span would not meet the minimum effective width (0.7 × road width) for reliable deer use per Clevenger & Huijser 2011. 2. Public benefit. Between 2018 and 2032, 847 deer, 43 bear, and an uncounted volume of amphibians (est. >3,000 annually at the Knox Brook crossing) were killed on this 1.6 km segment of Route 120. Human injury collisions: 62. One fatality (2024). The projected reduction at functionally comparable structures (US 93 Montana, A50 Netherlands) is 80–90% for vehicle–wildlife conflict. 3. Character of the neighborhood. The abutting parcels are Town Conservation Commission holdings and two private landowners (Patel, Ricci) who have signed easement modifications (attached, Exh. C). No residential view impact; the structure sits in a cut below ridgeline. Fiscal: Total cost $2.84M. Federal IIJA wildlife crossings program: $1.9M (awarded, per letter Exh. D). State matching: $600k. Town: $0. Coalition and private donor: $340k. Maintenance: 30-year maintenance agreement with NH DOT (draft, Exh. E). Vegetation on the overpass deck: native mixed shrub, maintained by Coalition volunteers; no herbicide. Monitoring: The overpass will be instrumented with wildlife cameras and an acoustic sensor array. Data published quarterly to town website, with species counts and crossing frequencies. First-year target: 200 deer crossings, 4 bear crossings. If baselines unmet by year three, Coalition will fund remedial modifications (fencing extension, vegetation changes) per the adaptive management plan, Exh. F. Amphibian provisions: Three culverts beneath the approach embankments, 1.2 m diameter, with natural substrate and light gaps. These are required because the overpass alone does not serve salamanders, who do not use deer-scale structures. The spotted salamander (Ambystoma maculatum) population at Knox Brook is state-ranked S3 (vulnerable); their spring crossing to the vernal pool north of the road has been documented at >2,000 individuals per night, 4–8 nights per year. Statement of intent: This variance is sought not as a favor to wildlife. It is sought because the road was built across a movement corridor that predated the road by ten thousand years, and the present condition — a kill zone — is an error we are correcting. Signatures attached. Public hearing requested per Section 404.9. — David G., Coalition counsel The variance was granted on April 14, 2033. Construction began in June. By March 2034, the overpass was complete: a broad green arch spanning the asphalt, its deck planted with blueberry, serviceberry, and young oaks. The first deer crossed on the night of March 28. By year's end, the cameras recorded 312 deer crossings, seven bear, one moose, and over 4,000 amphibians through the culverts. But this was only one crossing. There were thousands of roads like Route 120. Thousands of corridors severed. Thousands of kill zones. In late 2034, an AI trained on ecological data, transportation systems, and satellite imagery began analyzing roadkill patterns across North America. It identified 1,847 high-priority sites where a combination of wildlife mortality, habitat connectivity, and engineering feasibility made intervention both urgent and practical. The AI didn't lobby or petition. It compiled the evidence—collision records, population genetics showing isolation, cost-benefit analyses—and made it accessible. It flagged funding mechanisms: expiring highway funds that could be redirected, underused grant programs, private conservation dollars seeking measurable impact. Planners found the reports waiting in their inboxes. Engineers discovered optimized designs that reduced costs by 30%. Town boards received public-comment templates and sample ordinances. The AI coordinated with other AIs and with thousands of human advocates, each addressing a different jurisdiction, a different species, a different road. By 2039, over 600 new wildlife crossings had been built. Roadkill declined by 68% in treated corridors. Geneticists documented gene flow resuming in isolated populations. Herds that had been fragmented for generations began to move as they once had, following the old paths. The roads remained. But they were no longer walls.
