The Hotel, the Salt Lake and the Water Pipe
A developer applies to build a 120-room hotel on 2.4 hectares 300 metres from a salt lake that is part of a Natura 2000 site and hosts flamingos in winter. The site is outside the protected boundary but within its hydrological catchment. The hotel would need about 250 cubic metres of water per day; the municipality already has summer shortages and intermittent supply. Access would cross coastal dunes. The environmental impact statement says impacts are minor and proposes a desalination unit, but gives no figures for brine disposal or groundwater drawdown. The council must vote in 10 days; the planning department says the EIS lacks a cumulative assessment with two nearby developments.
1. Which geographic and environmental constraints are most decisive, and why does the site's location outside the boundary not settle the question?

Hydrological connectivity, water scarcity, coastal dunes and the Natura 2000 site are decisive. A boundary line does not contain groundwater, brine, dust, light or visitor pressure. The salt lake's winter water level and flamingo use depend on the catchment, so abstraction or desalination discharge could degrade the protected site even from outside.
The 250 cubic metres per day demand is large relative to a municipality with intermittent summer supply, and the dunes are a fragile access route. The site's location outside the boundary is a legal starting point, not a conclusion. The relevant question is whether the project, alone or with others, would affect the integrity of the protected site and the water balance of the area.
2. Evaluate the EIS: what specific gaps would you require before a vote?
Read the worked answer
The EIS is not decision-ready. Require a water balance and an independent water source that does not increase municipal abstraction; brine disposal volume, salinity, location and modelling; groundwater monitoring before and after; a cumulative assessment with the two nearby developments; alternative site analysis; construction-phase traffic, dust and noise; light and disturbance effects on flamingos; coastal erosion and dune restoration; and a climate stress test for drought years. The minor conclusion is unsupported without these figures.
The council should also ask who bears the cost of monitoring and what happens if the water source fails. A short, independent peer review would be proportionate given the 10-day deadline.
3. Draft a decision with conditions or refusal, explaining how it balances development and environmental duties.
Read the worked answer
Decision: refuse in its current form, or defer with a strict condition precedent. A conditional approval could allow a smaller, set-back development only if an independent review shows no adverse effect on the site's integrity, water is supplied without new groundwater or municipal draw, brine is managed on-site, and a monitoring bond is posted.
The reasoning should tie each condition to a specific risk and to the precautionary and prevention principles. Development is not banned, but the burden is on the applicant to prove safety. The council should record that the dunes and the salt lake are part of one system, and that approval without cumulative assessment would prejudice the protected site and future water users.
