If New Monroe Bay is the Beverly Hills of SimNation, then Halena Point 
must be the Bel Air of SimNation.  These two cities share some common 
traits:  low population density, full of trees, high EQ, good subway, 
popular mayor, and low unemployment.  But Halena Point has much higher 
land value compared to New Monroe Bay:  $310K+ vs $260K+.  Halena Point 
also has a much lower population, 70K+ vs 500K+.  In addition, when I 
designed the terrain for Halena Point, I actually tried to model the 
Sepulveda Pass area of Los Angeles.  The freeway is Interstate 405.  
The flat land between the moutains is San Fernando Valley (Van Nuys, 
Sepulveda, Reseda, and Northridge.)  The mountains are Santa Monica 
Mountains.  One side has Bel Air Estates, Sherman Oaks, Studio City and 
Universal City.  The other side has Encino, Tarzana, Woodland Hills, and 
Calabasas.  Of course the result looks nothing like the original because 
of space constraints and feasibility.  (A coast gives the industries that 
extra edge.)

Improvements I like to see:

Due to the small population, the city has low income.  But to keep the 
sims happy, it has to spend a lot.  The budget barely balances every 50 
years.  The fusion power plant will use up any savings over the years. 
(The $3 million is accumulated when the city was developing.  It had very 
dense population and low spending.  Over 2000 years city was very stingy 
and built nothing new.  Good thing they don't understand democracy.)

I want to build an arco, but it's not available to me.
