• 3.1.6 Runoff Coefficients
The runoff coefficients to be used with the Rational Method referred to in Section 3.2
_. "Analysis Methodology" can be determined based on either zoning classifications or the
1 types of surfaces on the drainage area. Table 3-2 lists the runoff coefficients for the various
types of zoning along with the zoning definitions. Table 3-3 lists coefficients for the different
kinds of surfaces. Since the Land Development Guidance System for Fort Collins allows land
development to occur which may vary the zoning requirements and produce runoff coeffi-
cients different from those specified in Table 3-2, the runoff coefficients should not be based
solely on the zoning classifications.
The Composite Runoff Coefficient shall be calculated using the following formula:
C = (!C,A,)/At
Where C = Composite Runoff Coefficient
C, = Runoff Coefficient for specific area A;
A; = Area of surface with runoff coefficient of C;
n = Number of different surfaces to be considered
A, = Total area over which C is applicable; the sum of all A;'s is equal to A,

areas with a minimum lot area of 6,000 square feet for one -family or two-family
dwellings and 9,000 square feet for a multiple family dwelling.
R-H High Density Residential District— high density residential areas with a minimum lot
area of 6,000 square feet for one -family or two-family dwellings, 9,000 square feet
for a multiple family dwelling, and 12.000 square feet for other specified uses.
R-P Planned Residential District — designation of areas planned as a unit (PUD) to pro-
vide a variation in use and building placements with a minimum lot area of 6,000
square feet.
R-L-P Low Density Planned Residential District — areas planned as a unit (PUD) to permit
variations in use, density and building placements, with a minumum lot area of 6,000

Mr. Glenn Schlueter
City of Ft. Collins
Storm Water Utility
235 Mathews Street
Ft. Collins, Colorado 80524
RE: Drainage Analysis for Mountain - Oak Neighborhood, Old Town Basin, Fort
Collins, Colorado
Dear Mr. Schlueter:
We have completed a drainage analysis for Mountain - Oak Neighborhood situated in the Old
Town Drainage Basin, Ft. Collins, Colorado. It is our understanding that the proposed
development plan consists of the following:
1. Removal of two (2) out structures.
2. Construction of a 4-car garage behind the existing residence/office located at 420
West Oak Street.
3. One new residence on the remaining open lot in the block.
4. An addition on to an existing residence/office at 420 West Oak Street.
5. An access drive parking area for the proposed garage constructed using checker
blocks.
The purpose of the checker blocks is to provide more pervious surface in the drive/parking lot
than a typical paved lot would provide. The blocks also provide a more aesthetically pleasing
parking lot which will help to improve the residential atmosphere of the neighborhood.
Our calculations have shown that there is negligible increase in runoff from the block due to the
proposed improvements. Due to the size of the contributing area studied (2.2 acres), the runoff
both historical and developed is minimal and would have absolutely no impact on the Old Town
Basin. Detention facilities would not be justified for this situation.
If you have questions, ple
Sincere / o
