The 1.49-acre project site is a developed single- family residential lot with a two-story home and gravel driveway connection between South Taft Hill Road and Moffett Drive. The lot has established landscaping adjacent to the home and native grasses east of the house. The site is located on the west side of South Taft Hill Road between Falcon Drive and Moffett Drive in Fort Collins, Colorado (Figure 1). The site is located within the Spring Creelc drainage basin. ,.� _ - -�G., a,R,3� t s�— � �: # #- � Vianity Map -,� Q 1� r��� zr��;"_ _r:- , ` — . �.:_ -- - � - _ _ _._;y . ,. ,,�` � __ . �..,,; r��i����� u�„� , ,. !N. �' +�• «';� 1� Y �, � . � �� T`3' _' r__ _ � ' ��-��j� � F..'�'.

Earth Engineering Company (2009) completed field investigations at the site, which included two borings drilled to 20 ft below ground surface (bgs). Groundwater was observed at 19 ft bgs in one location during investigations and sandy lean clay soils were observed at the surface and shallow subsurface soils. Per the NRCS Soil Survey of Larimer County (Exhibit B), the site entirely consists of Altvan-Satanta loams and is classified as being within hydrologic soil group B. These soils are anticipated to have a moderate infiltration rate when thoroughly wet and a moderate rate of water transmission. Per the flood insurance rate map 08069C0986G (effective May 2, 2012), the lot is located within Zone X. Zone X is defined as an area of minimal flood hazard and does not have a base flood elevation associated with it. Also, the site is outside of the City of Fort Collins mapped floodplains. (Exhibit C) Historically, site stormwater has drained with gentle slopes from the south to the north (historic basin A), onto the two private lots adjacent to the site. Stonnwater runoff that does not infiltrate into the native grasses ultimately discharges into Falcon Drive right-of-way to the north. Historic and developed drainage basins are shown in Exhibit D. The proposed site iinprovements include a single-story home with an attached recreational vehicle garage. Based on direction from the City of Fort Collins, any new stonnwater flows must be directed towards an adequate public outfall (South Taft Hill right-of-way). The grading plan was developed to direct all proposed impervious areas out to the South Taft Hill Road curb and gutter via either the gravel driveway or a proposed sidewalk chase near the northeast corner of the lot. This has resulted in two developed drainage basins. Developed basin A will encompass most of the project site (1.279 acres), while developed basin B(0.212 acre) will encompass the proposed site improvements, plus a section of the gravel driveway to be raised to drain east. Landscape retaining walls are proposed on the north, west, and south sides of the house, which will permit all roof drains to be collected within drainage swales around the house. A 6-inch storm drainpipe is proposed underneath the new driveway to route stormwater flows towards the northeast corner of the lot. Where possible, impervious areas and downspouts shall be routed into pervious areas with landscaping to allow for project stormwater infiltration and increased water quality with site runoff. The lot's total adjusted impervious area will increase 4,122 square feet (s fl per calculations provided in table below.

Using the Fort Collins Stormwater Criteria Manual (2018), the proposed stormwater runoff from the site is estiinated to decrease towards the north but increase towards South Taft Hill Road with development as indicated in the summary table below. 2-year 10-year 100-year Basin A Historic Runoff 0.61 cfs 1.04 cfs 2.76 cfs Basin A Developed Runoff 0.55 cfs 0.93 cfs 2.47 cfs Basin B Developed Runoff 0.32 cfs 0.54 cfs 1.38 cfs Based on the enclosed design, it is my professional opinion that the additional runoff generated by these site improvements will not cause adverse impacts to downsiream private properties. I hereby attest that this letter for the final drainage design for 3041 South Taft Hill Road was prepared by ine or under iny direct supervision, in accordance with the provisions of the Fort Collins Stornlwater Criteria Manual. I understand that the Ciry of Fort Collins does not and will not assume liability for drainage facilities designed by others. Thank you for the opportunity to submit this drainage memo.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. Rating Options Aggregation Method: Dominant Condition USDn Natural Resources Web Soil Survey 8/16/2023 � Conservation Service National Cooperative Soil Survey Page 3 of 4 Hydrologic Soil Group—Larimer County Area, Colorado Aggregation is the process by which a set of component attribute values is reduced to a single value that represents the map unit as a whole. A map unit is typically composed of one or more "components". A component is either some type of soil or some nonsoil entity, e.g., rock outcrop. For the attribute being aggregated, the first step of the aggregation process is to derive one attribute value for each of a map unit's components. From this set of component attributes, the next step of the aggregation process derives a single value that represents the map unit as a whole. Once a single value for each map unit is derived, a thematic map for soil map units can be rendered. Aggregation must be done because, on any soil map, map units are delineated but components are not. For each of a map unit's components, a corresponding percent composition is recorded. A percent composition of 60 indicates that the corresponding component typically makes up approximately 60% of the map unit. Percent composition is a critical factor in some, but not all, aggregation methods. The aggregation method "Dominant Condition" first groups like attribute values for the components in a map unit. For each group, percent composition is set to the sum of the percent composition of all components participating in that group. These groups now represent "conditions" rather than components. The attribute value associated with the group with the highest cumulative percent composition is returned. If more than one group shares the highest cumulative percent composition, the corresponding "tie-break" rule determines which value should be returned. The "tie-break" rule indicates whether the lower or higher group value should be returned in the case of a percent composition tie. The result returned by this aggregation method represents the dominant condition throughout the map unit only when no tie has occurred. Componenf Percent Cutoff.� None Specified Components whose percent composition is below the cutoff value will not be considered. If no cutoff value is specified, all components in the database will be considered. The data for some contrasting soils of minor extent may not be in the database, and therefore are not considered. Tie-break Rule: Higher The tie-break rule indicates which value should be selected from a set of multiple candidate values, or which value should be selected in the event of a percent composition tie. 3041 South Taft Hill Road USbn Natural Resources Web Soil Survey 8/16/2023 � Conservation Service National Cooperative Soil Survey Page 4 of 4 = c d � � � � � J � � �o m m x o °� a�i � � ao m °i �, ` m m � �, Q� 5 0 = x a i LL W v 'm v °' °' � ` `m .�°c o � � � � � i ° i m 2 rf6i y y E v � ^' m m c� z �- n o E m vuo � m a'^i � = a m � s J -p 2 y m LL �� p Y in m o �- = nn � °¢ �ao� �x � o ti o � � m �o= N3n �°cawo ooa�iEa � m E c �' > a °o 0 0 �n �� o x 3 = � o m a� c c � u� v o � o� o Q��@ o�� a u�i �' � � li � 0� a N O c: 'O '6 '6 i o O J N � p_'G N y Q � �^L O V U1 O.'-T' � 3 ' W _ T N QJ C o a li - Y O 01 N"O � C i UI N N � C V I/1 T W'6 � � O C� 01 o t; ��� o ��.a N�n o c a o .c > o m m � .n m E f6 0 o aai� ��-v � "' � aia o n a �.14c ° m c m cdi �� " cn E tr � �3 w u> � m m� a Q Y umi � n n�n d.n m� E ai �'m E v� LL m o U u � y ° 2 � v m� � a`� �n m a> o a� � i.�. > �o �� a i� Q =o 'o � c E � °1m �� m Y �n � a�i z°o E� m �° � c°�i � w v m�^ � u a m c� a m�� -o v a y° °�°> ' m a o >. �� �n d c o�� u. c O c U s �� �v 'a �= m u�i Q :a � v .6 T n c N W >_ o N� �> �� ai � N �'� m� W � c� p_Nj U l` ,t., 1A 't.' �G > > -y � � �j ~� N V ~ m � O �° o.
