Sorry this reply has taken so long as I was working on another project.
Already mention earlier but yes that statistic was wrong to thank you.
Well Los Angeles technically has four aquariums (not counting the science center or Sea Lab(It's closed for now until the owners can reach a rent agreement)). Cabrillo, Manhattan Beach Pier Aquarium, and Santa Monica Pier Aquarium are all extremely small and Aquarium of The Pacific only really serves Orange County and South Los Angeles county. Maybe a larger Aquarium between Los Angeles City and the Inland Empire(1) could work.
(1)I didn't realize this would be important but now it is. The Inland Empire is a general area where San Bernadino and Riverside meet. It also serves as both countys main cities and populations.
Well adding these new zoos is really meant to be for local communities not tourists.
Um wow ok I love the enthusiasm but not every major city in LA needs a zoo that would lead to over-saturation of the market, all I am proposing is for zoos in Los Angeles to be easy to get to. However, I think that your idea for different themed zoos in different areas is a really great idea that could actually work really well.
Now time to go through all of the zoos you suggested:
Riverside:
- Corona: Giving South Corona a small zoo might not actually be a terrible idea. It is the westernmost part of the Inland Empire and could also serve as a nearby zoo for Lake Elsinore.
- Moreno Valley: This is so close to the much larger Riverside city it wouldn't make sense to put a zoo here. Maybe a safari park at the east or south ends of the area but I wouldn't.
- Riverside: Defenitly
- Murieta: Mureita and Temecula are both very close so you would have to pick a city. I would go with Murieta, its further north to provide a zoo for smaller areas like lake elsinore while also staying away from SDZSP.
- Temecula: See the above.
San Bernadino:
- Ontario: This is far enough away from every other major city to work. Maybe move it closer to Pomona.
- Fontatna: No and I will go in depth later
- Victorville: Also has Apple Valley and Hesperia. The region already has a zoo that I would do anything to get rid of so maybe a Living Desert like zoo.
- San Bernadino: So Riverside, Rialto, San Bernadino, and Fontana are all in very close proximity to each other so what would be best is a zoo somewhere between all three. Actually out of every zoo mentioned I believe thiszoo would need to be the biggest and should really happen.
- Rialto: See the above
- Rancho Cucamonga: Share a zoo with Ontario.
Ventura
- Oxnard: Too close to Santa Barabara
- Thousand Oaks: This could work as a major zoo spot.
- Ventura: Too close to Santa Barabara
- Simi Valley: Share a zoo with Thousand Oaks
Los Angeles
- Burbank: Too close to LA zoo
- Downey: Could have a minor Zoo
- El monte: A tough decision maybe a minor zoo or aquarium
- Glendale: Too close to Los Angeles
- Ingelwood: Ingelwood, Torrance, and Long Beach ae all viable spots for a major zoo. I would suggest a major zoo somewhere in between all of them.
- Lancatser: Could use a small zoo and share with Palmdale
- Long Beach: See Ingelwood
- Norwalk: Share with Downey
- Palmdale:Share with Lancaster
- Pasadena: Too close to Los Angeles
- Pomona: See Ontario post
- Santa Clarita: Could do well with a major zoo. Could also cater to tourists because of it's proximity to Six Flags.
- Torrance: See Ingelwood post
- West Covina: Share with el monte
