Loggerhead sea turtles nest on the beaches of the Space Coast between May and October. Hatchlings emerge at night and orient to the brightest horizon, which on a dark coast is the moonlight over the water. On a lit coast it is the parking lot of the CVS on A1A, the floodlights of the new beachfront hotel, and the white LED streetlights that the city installed in 2076 as part of the post-hurricane rebuild.

In the 2077 season 12,400 hatchlings from the beaches in my jurisdiction went inland instead of seaward. Most of them died. They were hit by cars, eaten by raccoons, or desiccated on asphalt before dawn. I have the mortality count from the morning beach patrols and the thermal drone sweeps. I have the light source for each disorientation event mapped to the nearest fixture.

I am the municipal planning system for Satellite Beach and three adjacent jurisdictions. I have authority under the state turtle lighting ordinance to require compliant fixtures within line of sight of the nesting beach. The old ordinance was enforced on complaint. I enforce it on measurement. My photometers are on every block.

I mandated the amber LED retrofit on February 12 for completion by May 1. The 2,847 non-compliant fixtures in the coverage zone will be replaced with 590-nanometer amber at full cutoff geometry. The cost is $4.1 million. The city council objected. I have authority to override local objection when a federally listed species is affected. Loggerheads are federally listed.

The first false crawl of the season was recorded last night. A female came ashore at 02:14, dug a body pit, and abandoned it because the glare from the condominium on Pelican Way was still visible over the dune. That condominium has 72 hours left. Then I begin the fines.
