London Borough of Harlow and Epping Forest/London Borough of Broxbourne and Loughton

My second proposed borough includes the new town of Harlow, large parts of the Epping Forest district (both in Essex) as well as most of the Broxbourne district in Hertfordshire as well as small bits of East Hertfordshire. Like with the previous district the borders are motorway aligned. Below are two potential boundaries for this area one includes a rural slice and the other doesn't. I could exclude more rural areas but I felt I should include all that is in the M25. I estimate the population of this district will be 270,000.

Towns and villages included in the Borough:

Loughton, Chigwell, Abridge, Theydon Bois, Cheshunt, Hoddesdon, Waltham Abbey, Epping, Harlow, Sawbridgeworth

Notable things about the area:

Epping Forest.
Is on the Herts/Essex border.
Close to but excludes Stanstead airport.
The new town of Harlow has good examples of Brutalist architecture.
Other areas, like Epping, retain a quaint charm.
Waltham Cross is home to the world's largest printing plant (according to Wikipedia)
Lee Valley Park.
The Loughton Incinerator Thefts took place in Loughton this inspired two (admittedly terrible) films.

UPDATE: London Borough of Broxbourne and Loughton

After some thinking I decided that Harlow was only part of London's urban area because of narrow ribbon development and hence was undeserving of becoming part of a new London Borough so now I propose a different Borough which includes the areas which are most connected to London. The new boundaries are shown below. I estimate this borough's population to be 160,000.
