You've got a few options: as others have said: 1- drill weep holes & seal wood so it doesn't rot. 2- pull some pavers & dig to install a drain. 3- plane down the wood/notch the corner so it drains over the edge (my personal fav) 4- pull pavers & re-level patio so it's above the wood & pitched proper again.
Standing water removal costs $1,600 to $6,575. Most homeowners install a drain in their yard due to drainage issues, so there's often a little (or sometimes a lot of) standing water. Contractors will have to drain the water before they begin installing your system.

Water erosion is one of the most common reasons for a patio to sink or dip over time. Below all of the foundation gravel and sand is all-natural soil. This soil can be affected by water erosion causing a dip in your patio.
Boiling Water
 Boiling water is another simple and effective drain-cleaning hack. Boil at least a quart of water and slowly pour it down the drain in smooth spurts. You need to give the water time to work its way through clogs and destroy blockages, so don't pour it all at once.
Concrete flooring is an extremely durable, hard-wearing type of flooring. When laid correctly by a concrete specialist, concrete flooring boasts an extremely long lifespan, with the same high performance and flawless aesthetic. However, standing water is one of the most common causes of damage to concrete flooring.
Your Drain System is Clogged
 Since patios are outdoors, there is always the possibility of larger debris finding its way into the drainage system. Leaves, in particular, tend to get trapped in drain channels, making it difficult for water runoff to easily flow through.
Organic mulches like wood chips, bark, and straw absorb water. Inorganic mulches like rocks, gravel, pebbles, and rubber don't absorb water but may allow water to drain through the gaps between pieces.
If you've spotted water building up at the edge of your patio and taking a long time to drain away, you can install an underground drainage pipe system to cure the problem. Other wet areas of the garden can be drained the same way. However, there must be somewhere for the water to go.

Water can compromise your foundation's strength in as little as 72 hours under severe conditions, though the process often takes months or years. The concrete damage usually starts subtly—hairline cracks slowly widen, creating paths for water seepage.
