A group of community members taking action to ensure that all development on Signal Mountain is responsible and matches the "countryside residential" environment of the area.

The Situation

Signal Mountain and Walden’s Ridge are uniquely vulnerable to overdevelopment — steep terrain, limited access roads, fragile ecosystems, and aging infrastructure make them ill-equipped to handle significant new housing.

Yet developers are moving fast to convert large parcels into sprawling subdivisions.

Current Proposals Include:

  • Several developments near the top of Roberts Mill Road — up to 1,500 new homes, adding 4,500 to 15,000 daily vehicle trips to already overburdened roads

  • Additional ridge properties quietly under review

We are Save Signal Mountain — a group of residents committed to preserving the safety, livability, and natural character of our mountain community.

The Impact

  • Fire & Emergency Services

    Due to the layout of our area, the response time for 90% of fire incidents is less than 24.8 minutes - compared to best Hamilton County response time of 13.4 minutes and the national recommendation of 14 minutes. 

    • Most areas lack hydrants, and narrow, winding roads with limited interconnection delay response.

    • More homes = more calls = longer delays for everyone.

  • Roads & Traffic

    • Roads on the mountain are mostly rural and steep, and the there are no major upgrades planned. The only improvements on the horizon are “preventative maintenance” starting in 2040.

    • Traffic on our three mountain roads has grown 13% in just four years, now exceeding 23,000 trips per day.

    • Congestion is already a problem — and the proposed developments near Roberts Mill Road alone could add up to 15,000 more daily trips.

  • Schools

    • Signal Mountain elementary schools are already 107 students over their capacity of 1,279 — and projections suggest up to 1,000 more students could be added from new developments, nearly doubling enrollment with no clear plan for expansion.

    • More families from dense subdivisions will stretch classroom space and resources even thinner.

  • Environment & Water

    Environment & Water

    • These subdivisions are proposed in areas with steep, erosion-prone slopes, which the county’s own plans label as "unsuitable for dense development."

    • Most lots would rely on septic systems, or risky decentralized drip dispersal systems which are prone to failure and can contaminate existing creeks.

Take Action

Uncontrolled development is threatening the safety, environment, and character of Signal Mountain.


Developers are rapidly pushing new subdivisions onto land that can’t safely or sustainably support them.

  • Emergency response times are already dangerously slow.

  • Schools are strained and nearing capacity.

  • Roads, water, and sewer infrastructure are inadequate.

  • Irreplaceable forest is being bulldozed.

Help us stop irresponsible development before the damage is permanent.
