Living in Ukay Perdana here. Not exactly in the Sierra Hijauan, but I could give some opinions in terms of the life around the area.

- If you're retired or WFH most of the time, the hilly/forest environment is quite nice and chill vibes.

- I wouldn't really recommend it if you're working in KL city centre & going to commute from here, traffic kinda bad. I expect it will be even worse once EKVE opens.

- Bottleneck will be at Ukay Perdana junction to MRR2. There's another road to MRR2 from Petronas Bkt Antarabangsa, but you're not gonna able to cut some time on this road either. Traffic jam starts around 7am. expect to be trapped 15min-30min just to get out of the junction to MRR2.

- Landslides, most of the recent landslide cases that's near residential are around 'Jalan Kelab Ukay' area. Though there's currently ongoing hill slope reinforcement project of some sort from the council for the hills in this area.

- Schools, nearest would be SMK Lembah Keramat & SK Hulu Kelang, both roughly 6km away.

- Clinics, plenty, just type in clinic in google maps, you should be seeing at least seven in this area alone. Private hospitals, i think Columbia Setapak is the nearest. Gov hospital would be Hospital Ampang.

- Markets, nearest supermarket is Giant Bukit Antarabangsa. Other alternatives are Giant Permata, Aeon Big Wangsa Maju, Hero Market.

- Malls, pick ur poison. Melawati Mall, Wangsa Walk, KL East Mall, Alpha Angle.

- Crimes/Safety, can't comment much on this as I don't have the information. There's a small police station Balai Polis Ukay Perdana just nearby. I see police patrolling the main roads and residential areas fairly often.
