The City of Vancouver is heading to Ottawa with a proposal for a partnership on 20 new affordable-housing sites.

At meetings Mayor Gregor Robertson is attending this week, he will suggest the city supply $250 million worth of land in exchange for a $500-million federal investment in housing over five years.

According to a Globe and Mail report, the projects would collectively provide 3,500 affordable-housing units. However, a document provided by the city puts that number lower, at 2,616 units.

If federal funding does come through, construction on some of them could begin as early as next year.

The city refused the Straight’s request for a list of the 20 addresses. However, it did share a rough map of the sites. It shows 23 proposed projects clustered in the Downtown Eastside, along the north side of False Creek, and on the southeast edge of the city. From those 23 locations, 20 will be selected for development, pending an agreement on federal funding.

In False Creek, three locations are just off the north side of the Cambie Street Bridge and another three are west of there, closer to the north side of the Granville Street Bridge. One is further into Yaletown.

Five of those seven sites are long-term projects, not expected to open until after 2021.

In the Downtown Eastside, two locations appear near the intersection of Pender and Abbott. Another three are east of Main Street, on Alexander or Powell streets.

There is also a building proposed for near the intersection of Kingsway and East 7^th, and one just south of Kingsway and Fraser.

Another eight buildings are proposed for southeast Vancouver, around the intersection of Southeast Marine Drive and Rupert Street. There is also one site planned for Southeast Marine Drive between Cambie and Main streets.

All but one of the 16 locations outside of False Creek are forecast for completion within the next two to five years.

The Liberal government is expected to table its first budget in the weeks ahead. And a November 2015 mandate letter Prime Minister Justin Trudeau sent to the Ministry of Families, Children and Social Development, states that office should focus on affordable housing.

The ministry should “prioritizing infrastructure investments in affordable housing and seniors’ housing, including finding ways to support the municipal construction of new housing units and refurbishment of existing ones”, it reads.

According to a City of Vancouver document attached to the map above, the 23 construction projects would create between 2,000 and 3,000 jobs during 2016 and 2017 and an additional 8,000 to 9,000 jobs between 2018 and 2020.
