ST9302-CS 940116Sandy Lake Sewer Line Notes: Approximate cost to construct the sewer line in Sandy Lake one million dollar Approximate cost of improvement to the Sandy Lake Lift Station and force main $600,000 Total cost approximately 1.6 million dollars. An alternative to the Sandy Lake sewer line would be construction of a sewer line from Heartz Rd. to Moore Rd. turning the sewer line south at Moore Road to Stream G6 (immediately south of Villawood lake). At that point, the sewer line can take two directions. 1) down Stream G6 tieing into the new 30" sewer line south of Bethel School Road 2) continuing Moore Road ail the way down to Grapevine Creek. The approximate cost of the Moore Rd. sewer line in Stream G6 is about 1.2 million dollars. The approximate cost of the sewer line down Moore Rd. is approximately 1.6 million dollars. The total length entirely in Moore Rd. is shorter however because of the topography of Moore Road there will need to be approximately 3300 foot of tunnelling, going down the creek there would only need to be about 1800 foot of tunnelling. To take all of the area that currently is south of Sandy Lake and not in the MUD completely out of the MUD would necessitate the construction of another sewer line in Mockingbird. The approximately cost of this sewer line is $200,000. This sewer line will essentially start at Cherrybark continuing south past Mockingbird Elementary to Hawk Lane, going west on Hawk Lane and then going between houses on Hawk Lane back to the sewer line in Stream G6. There currently is a sewer line between the two houses on Hawk Lane and there currently is a sewer line in Stream G6. It is anticipated that that sewer line will need to be approximately a 10" sewer line. It will be picking up 177 additional homes that are not in the MUD, however, they flow to the MUD. The reason I am looking at other options to take all the land out of the MUD is that I have some concerns as to whether or not we went in Sandy Lake and made improvements to the lift station if Paul Phy would come back and say that if the property south of Sandy Lake is going to stay in the MUD somebody needs to pay the annexation fees to have that property annexed into the MUD. It is my understanding that the annexation fee is approximately $2300 per acre. Based on my rough calculations, there are approximately 225 acres of land we are speaking of and the annexation cost would be about $520,000. I am quite sure that Paul Phy would be looking to the City to pay that cost. If that $520,000 was added to the 1.6 million that we are already talking about then we are looking at about 2.1 million dollars to construct the Sandy Lake, the lift stations improvements and annex the property into the MUD. The annexation of the property has not been discussed but Mr. Phy has alluded to the fact that we would address that after we have addressed the sewer problem. It is my belief that Mr. Phy will be approaching the City for that annexation. Not only that, all those properties in that area will then have to start paying the 15 cents tax. This could be a political nightmare. If we were to take all the property out of the MUD and this would include building the Moore Road system will take the higher number of the two and the Mockingbird system the total cost to the City would be about 1.8 million dollars. This might be the cleanest, best route to take short of taking of taking the MUD over entirely. If the City were to take over the MUD entirely, then it would be very wise to spend money on the lift station improvements because those improvements will be needed in the future. By taking the MUD over, we would not have to worry about annexing any property into the MUD, and that would save 1/2 million dollars. It seems foolish for the City to have to spend about 1.8 million dollars to take property out of the MUD and then once we take over the MUD we have to go back and spend $600,000 to upgrade the lift station. However, before the City makes a commitment on the Sandy Lake it seems to reason that there needs to be conversation concerning whether or nor Paul Phy is going to expect the City to then have the property annexed into the MUD. An additional 1/2 million dollars could be a blind side to City Council and staff if we recommend going in Sandy Lake and doing the lift station and then Mr. Phy hits us with an additional 1/2 million dollars. There could also be a trade off in this situation which would be not putting in the Mockingbird system but picking up the Braewood Subdivision. Braewood actually has more homes in it than the Mockingbird line would pick up. The City would be taking more homes off, however, Paul Phy would then have to come back and figure out a way to adjust his MUD line. The acreage is very similar, maybe he would wave the acre charge however, you would have the people in Braewood no longer in the MUD and legally no longer paying the 15 cents and we would have to be annexing the property off Mockingbird into the MUD and they would have to pay the 15 cents. Again, this could be a political nightmare. Bill Anderson also approached me about the possibility of building a lift station on Barbara Austin's property and pumping the sewage in a force main down Moore Road. That force main would have to go almost to Christi Lane before you could get gravity flow back to the south into the Grapevine Creek. The one thing to when I talk about the cleanest thing, we would have to look at the Grapevine Creek Sewer Main to be sure that it could handle the addition of about 700 additional homes in it. It probably would not be a problem, it has been sized to handle commercial and the roof tops would be peaking off the peak of the commercial property. But it still would need to be looked at. file/kgriffin/mud
