The Environment Agency flood map for planning. Councils use it to decide when a flood risk assessment and the sequential test are needed. It is indicative and does not show whether a particular property will flood.
Flood map ↗
Ramsar wetland 162 m away: Benfleet and Southend Marshes
Work nearby can need a habitats assessment.
Harm to a protected site is only accepted where there is no alternative and an overriding public interest.
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
SSSI 162 m away: Benfleet and Southend Marshes SSSI
Natural England may need consulting, depending on what is proposed.
Sites of special scientific interest are the best wildlife and geological sites in the country. Development likely to harm one is rarely permitted.
Also on the record

Not affected
Outside flood zones 2 and 3 · Not green belt · No scheduled monument at the site
