It is all here with out of date 2006 contour lines before the runway extension was built.

Interesting points made here about Southend and its new noise rules. A very quick read and I might have read it wrong will have some implications if easyjet want to base more than 3 aircraft at Southend as movements after 11pm are restricted to just 3 a night as night includes the times beween 23:00 and 23:30
No passenger flights may be scheduled to arrive or depart during Night Time Hours, except that up to a maximum of 90 passenger flights in any one calendar month may be scheduled to arrive between 23:00 and 23:30 local time, such flights to be included in the Monthly Quota.
Also some aircraft are now banned
No aircraft with a noise level exceeding QC2 shall take off or land at any time, unless they are emergency flights, military flights, Government business flights or police flights, maintenance flights or diversions. QC4 aircraft using the airport for maintenance may land or take off only during the Day Time (0630-2300 hrs) and the total QC4 aircraft movements will be limited to 60 per annum
