Have been looking in this forum for info on my problem and seem to be seeing alot of good info but I have a pretty specific problem so if you can bear with length of this thread I will greatly appreciate any suggestions. Redirection to other threads addressing similar problem would be great too. BACKGROUND: Was notified today that I had been awarded the contract to maintain a senior's apartment bldg. When preparing my bid, I surveyed the turf and bed areas a couple weeks ago and then subsequently stopped by to see the effects of the landscape contractor progress I noticed lots of standing water in an areas where drainage was limited or non-existent. The landscape contractor finished laying sod and the whole project at least a week ago. Right now in the Willamette Valley of Oregon it has be hot and dry and so it makes sense to hit the sod with lots of water to get it going and established. The grass is extremely high and needs mowing bad.... The bldg is orientated on a N - S aspect with the problem area in the shade most of the day (East Side). Noticed the beginnings of mushrooms in the turf and days are obviously shortening. CHALLENGE: Am not sure this is usual protocol, but when the property manager called to say my quote had been accepted it was conditional on the owners approval of my turf mowing quality here the next couple days. So I stopped by tonight to see how high the grass was....well in some places it was approaching 6 - 7" and others where the sod was last laid a more manageable height. But my main concern and actually this problem is multiple is that where the sod was laid first and is oldest the irrigation programming has literally created a swamp..... In at least two low spot the grass is beginning to die and the sod is like walking on a sponge. The way I see it how I approach this with the owner will either cost me this $570 month maintenance contract or he'll respect my professional recommendations. The bldg interior in the process of being completed, and it will probably be a couple more weeks before seniors start moving in. There is no way I can mow these wet areas without seriously damaging the turf. WHERE I NEED SOME IDEAS TO SOLVE PROBLEM: This is how I see it... - Explain problem to owner and mow areas of turf that are not going to get messed up because of over watering. - Get irrigation plans and programming schedule and apply rules of irrigation management. Securing the zones where I have standing water until it drys out and then adj the sch to irrigate the correct amount. I can't help but feel that the root of the problem, INADEQUATE DRAINAGE SYS will impair my ability to irrigate these turf areas effectively. The weather is dry here with temp in 80' and 90's, what is the rule of thumb on when to mow turf that is soaked and not grossly damage it? Thanks for taking the time to read this problem sorry it took so long explain the problem. I have as references Sunset's "Western Garden Book" and "Turfgrass Management 6th ED"
