Work to start on Doug Creek drainage fixes; City sets Camp Creek public meeting Oct. 22
City Engineering is moving forward on planning, as well as construction, on three Westside drainages that have been identified as vulnerable to burn-scar flooding.
The same consultant, Wilson & Company, has been hired for all three - Camp Creek and North and South Douglas Creek. The goal is to “develop alternatives and a preferred course of action for construction of flood mitigation structures/ facilities,” a city press release states.
The Douglas process is somewhat farther along, with an analysis already having identified the worst problems and repairs due to start this fall.
Funding for the consultant work, and for some of the North and South Douglas costs, will come from $8.8 million in funding reserves set aside for stormwater needs by Mayor Bach earlier this year. However, Camp Creek improvements have been estimated at more than $10 million. “We will be looking at various grant opportunities to help cover the construction cost,” explained Tim Mitros, city stormwater engineering manager. “I also expect that we will ask that additional funds be budgeted in later years.”
Here are other updates:
Camp Creek - City Engineering and Wilson have scheduled a community meeting Oct. 22 at 6 p.m. at Coronado High School to share ideas on flood-mitigation upgrades.
The drainage starts in National Forest land, including areas ravaged by the 2012 Waldo Canyon Fire. Its path takes it through the Glen Eyrie property (west of 30th Street) and then south through Garden of the Gods, Rock Ledge Ranch and the Pleasant Valley subdivision en route to Fountain Creek.
Engineers have considered such ideas as a detention pond in the Garden area and changes to the lined ditch through Pleasant Valley, but nothing specific has been proposed yet. At the meeting, “we'll talk about very broad goals and take input from stakeholders,” said City Civil Engineer Mike Chaves. “We'll hear what the concerns are, and use that to help with our concepts.”
Despite the burn-scar issue, he said the city wants to be careful not to over-spend. “We could go out quickly and build structures to handle it [the higher level of flooding]. But then 10 years later, when things get more normalized, we'd have structures bigger than needed. So our question is how do we handle what comes down in a safe manner and not waste money?”
North Douglas - This drainage starts in the mountains north of the city. Its lower reach, called Reach 4, flows under Garden of the Gods Road at Buckingham Drive and past Colorado Technical University to Monument Creek. That part of Reach 4 is concrete-lined and has some breaks and cracks. Bids for repairs will be going out soon, with the expectation that contractors could begin work by November, according to city officials. Work on its upper part (Reach 2), which had some failures this summer, is already out to bid and due to start in October.
South Douglas - This drainage starts in the mountains above the Flying W Ranch (which was destroyed in the Waldo Canyon Fire last year). The segment north and west of Garden of the Gods Road is Reach 1; Reach 3 is the segment south of where South Douglas Creek crosses the road about a quarter-mile east of 30th Street as a concrete-lined channel to Centennial Boulevard.
A contract for Reach 1 is in the process of going out to bids, with work expected to start in October. As with North Douglas, new problems with the upper reach occurred this summer. Reach 3 work could start by November, according to City Engineering.
