Narrative:
As we were descending via the HHOOD3 arrival into pdx we were given clearance to ommsi and a cleared alt of 6200 feet. Then after calling the airport in sight; we were cleared direct to toloc (OM on the ILS 28R) and told to cross toloc at or above 2000 feet. I was hand flying as we approached toloc at about a 45 deg intercept to final. There was a peak about 15 southeast of pdx which I could see we were clear of; but as we passed over the top of it we got the GPWS terrain alert. I stopped the shallow descent we were in and the alert went away. Looking back at our position I should have been about 1000 feet higher crossing that peak to be on a 3 degree glide path. We continued to a normal landing. I should have looked more closely at the charted terrain on the approach chart and stayed higher longer; but once we got the clearance to cross toloc at or above 2000 feet; I continued a shallow descent. It could have been prevented if I had done a quick 3/1 descent calculation while we were still at about 6000 feet.

Title: A320 Captain reported receiving a GPWS 'Terrain' warning on a visual approach into PDX airport.
Narrative: As we were descending via the HHOOD3 arrival into PDX we were given clearance to OMMSI and a cleared alt of 6200 feet. Then after calling the airport in sight; we were cleared direct to TOLOC (OM on the ILS 28R) and told to cross TOLOC at or above 2000 feet. I was hand flying as we approached TOLOC at about a 45 deg intercept to final. There was a peak about 15 SE of PDX which I could see we were clear of; but as we passed over the top of it we got the GPWS terrain alert. I stopped the shallow descent we were in and the alert went away. Looking back at our position I should have been about 1000 feet higher crossing that peak to be on a 3 degree glide path.
