Hi Product Hunt,
A shop in a low street can look perfect in the dry season. The water shows up in the wettest month, after the lease is signed and the stock is on the floor. Tenants and small landlords almost never have the river history for a place, and the data that exists is in the wrong format and the wrong language.
HighWater Brief reads nearly 30 years of modelled river flow near an address and turns it into one printable page:
- how the area has flooded: big peaks compared with normal, the wettest months, whether it is getting worse, when the rainy season peaks
- what to ask the landlord
- which clauses to add to the lease
- how high to keep stock off the floor
It is in English, Burmese, Thai, Vietnamese, Filipino, Bengali, Swahili, French and Spanish.
What it is not: an engineering survey. The river data is on a grid of about 5 km, so it can pick the wrong river, miss drains and small streams, and cannot see your building. Storage heights are rules of thumb and the brief labels them as estimates. Use it with local knowledge and local hazard maps. Every brief says this.
Try it free with no sign-up: seven example addresses, or your own pin. Your first full brief is free with an account; after that a brief is $2. Rainy-season alerts are $1 per month per address, and property managers get 50 addresses, a dashboard and CSV import for $39 per month.
I would love feedback from anyone who has rented in a flood-prone area, and from native speakers of the languages: wording that reads wrong to you is a bug, please tell me.
