City of Loveland Stormwater Engineering logoIn 1986, the City of Loveland Master Drainage Plan was developed, and in 1987 the Stormwater Utility was established following several years of study by City Councils, citizen groups, City staff, and consultants. The plan outlined improvements to the existing system and established criteria that developers must follow for new developments. Between 1986 and 2001, slightly over $8 million was spent on improvements with $26.7 million in 2001 dollars left to complete. In order to accelerate storm drainage projects, fees increased 25 percent on January 1, 2002. Remaining stormwater capital improvements will take at least another 34 years to complete based on existing funding. The projects include building of regional detention ponds, increasing the size of existing storm sewers, constructing new storm sewers and channels and solving flooding problems following heavy rainstorms.

Master Plan Prioritization Plan

The Master Plan Prioritization Plan is broken down into major capital projects over $500k and minor capital projects under $500k for budgeting purposes.

Prioritization Plan - Decision Making Matrix

The major capital projects were separated out from the minor capital projects to form two matrices. The decision making matrix consists of categories that provide a comparison of all the projects. The categories in the matrix including flooding, media coverage and citizen complaints, damages, risk of life, maintenance problems, water quality and cost. Each category was ranked based on the opinion of the entire stormwater staff. Then each category was weighed based on its relative importance in three weighing scales (1-15; 1-10; and 1-5). Based on this comprehensive evaluation, all the projects are ranked based on highest score. The final ranking of all the projects was based on the 1 to 10 scale which was determined to be a good middle range ranking system to the other two scales.

This prioritization plan can then be used for planning and budgeting for the next 10 years. The major capital projects will be interchanged with the minor capital projects as timing and funding become available. Coordination with Public Works Engineering on road projects will also be an important factor in determining the timing of each project as many of the stormwater projects are along major roadways within the City. All costs are preliminary, and most of them come from the original 1986 master plan. Costs may need to be more refined, if they land in the top five ranking, in order to prepare a better number for budgetary purposes. The decision making matrix will be re-evaluated every year based on new data and input.
