The DSSP is one of the least pleasant components of the inner city multi family project. First question most people would have is, what is the DSSP? Second question, why is it so unpleasant?
It stands for the Development Site Servicing Plan. I don't know what this officially means, but to me it is the requirement for onsite storage and slowed release of storm water (mostly rain) into the City storm trunk. The City likes to ratchet up the criteria that must be met on a regular basis, and it is becoming less viable, and more costly each year. This mostly explains the unpleasant portion of our question above.
Each DSSP is unique and requires the services of a Civil Engineer to draw the plan, and ample fees to the City to review the plan. The DSSP is also reviewed slowly by two departments, thus it really can slow the overall building permit down. You can't start building until the DSSP and BP are passed, so the wise builder gets on top of the DSSP immediately. You also cannot apply for the DSSP until the DP is passed, so the timeline gets longer and longer. The approved DP is needed because that plan shows features like roof drainage and landscaping, all essential components of the DSSP calculations.
I am going to show the DSSP over a few postings, starting with the general plan (an unapproved variety), discuss the costs, and eventually show some more of the detail in what actually goes into the DSSP. Hopefully, and soon, we will be on site and show the installation of the various components from the property and into the street.
Here is the overall DSSP drawing. There is a lot of information on the page, all of it is important. First thing to note is each circle is a manhole, these are expensive components. The most expensive component is the box structure. That is a very costly structure. We will show these individually as the project progresses through the permitting stage.
