In 2004, San Diego County narrowly passed TransNet, a sales tax to fund transportation projects. EHL played a leading role in ensuring that the measure will generate nearly $1 billion for wildlife habitat as mitigation. The first monies have been allocated.

The San Diego Association of Governments allocated $1 million for a variety of important land management and monitoring functions. These include creation of a database for all conserved lands in San Diego County, managing and restoring vernal pools, protecting lands from off-highway vehicles, and invasive species removal and erosion control near Lake Hodges. Eventually, a new regional monitoring infrastructure for conserved lands in the region – the Regional  Environmental  Information  Center – will be set up.

EHL serves in an advisory capacity on TransNet allocations.
