1. Project Overview
The Solera Subdivision is a proposed residential and mixed use development at the northern corner of NE 10th
Ave and Sunset Blvd in Renton, Washington. The project consists of 151 for-sale town home units,
approximately 521 apartment units and roughly 39,000 sq ft of non-residential or commercial space. The
project consists of 6 existing parcels which will be subdivided into 7 parcels including realignment and
dedication of a portion of Jefferson Avenue NE ROW totaling 11.8 acres (Figure 1-1). The realigned and
expanded public right-of-ways will bisect the site connecting NE 12th Street to NE 10th Street and Harrington
Place to NE Sunset Boulevard. Additional frontage ROW dedications will be provides as well.

2. Existing Conditions
The site is substantially developed and paved in its existing condition. The current use, the Greater Hi-Lands
Shopping Center and its accompanying surface parking lot occupy the majority of the site. A 1.1 acre parcel, in
the southwest corner of the site, is undeveloped - consisting of lawn and gravel. The majority of the site slopes
to the southwest at grades of 2-5%. The northern extent of the project site, near the existing US Bank building,
slopes toward NE 12th St at grades of 2-5%. See Figure 2-1 for an overview of site topography.

Drainage Report – Solera Unit Lot Subdivision
Appendix A
3. Conditions and Requirements Summary
In compliance to the City of Renton city code, proposed development shall be in accordance with a city
amended version of the 2016 King County Surface Water Manual City titled The Renton Surface Water Manual
(RSWM).
CORE REQUIREMENT NO. 1: DISCHARGE AT THE NATURAL L OCATION
The project proposes to connect to existing public stormwater conveyance systems in NE 10th St and NE 12th
St. These storm drains converge within ¼ mile downstream.
CORE REQUIREMENT NO. 2: OFFSITE ANALYSIS
An offsite analysis has been conducted, see Section 3.
CORE REQUIREMENT NO. 3: FLOW CONTROL
According to the Flow Control Application Map, from the RSWM the development is required to meet the Peak
Rate Flow Control Standard – Match Existing. Developed flows must match 2, 10 and 100-yr peak flows which
existed on site prior to May 1979. Existing improvements on the site were built in phases over a range of
years from 1958 to 1977, and so for the purposes of this analysis, “existing conditions” are defined as the
current land use.
CORE REQUIREMENT NO. 4: CONVEYANCE SYSTEM
Proposed conveyance system elements, both onsite and offsite, shall be analyzed, designed and constructed
according to RSWM requirements. Conveyance system calculations will be provided during construction
document permitting following entitlement.
CORE REQUIREMENT NO. 5: CONSTRUCTION STORMWATER PO LLUTION
PREVENTION
Erosion and Sediment Control measures and Stormwater Pollution Prevention and Spill Control measures will
be applied through a Construction Stormwater Pollution Prevention (CSWPP) plan to be prepared during
construction permitting.
CORE REQUIREMENT NO. 6: MAINTENANCE AND OPERATIONS
Operation and Maintenance measures for stormwater infrastructure will be provided prior to Final Plat
Submittal.
CORE REQUIREMENT NO. 7: FINANCIAL GUARANTEES AND LI ABILITY
Bond quantities for the City of Renton will be provided prior to construction permitting.
CORE REQUIREMENT NO. 8: WATER QUALITY
The project is required to apply Enhanced Basic WQ treatment due to the Commercial and multifamily land
uses. To achieve this bioretention facilities have been proposed throughout the site, See Section 5 for a more
detailed analysis.
KPFF Consulting Engineers
4
CORE REQUIREMENT NO. 9: ON-SITE BMPS
The project is satisfying the on-site BMP requirement by demonstrating compliance with the LID Performance
Standard as described in Section 1.2.9.1.B in the RSWM. The LID Performance standard is being achieved
through the use of bioretention facilities dispersed throughout the development. See Section 6 for a more
detailed analysis.
SPECIAL REQUIREMENT NO. 1: OTHER ADOPTED AREA-SPECI FIC
REQUIREMENTS
This project is within the Sunset Area Surface Water Master Plan (CH2M HILL, 2011) which requires the
developer to install an 8 ft wide bioretention facility along the south side of NE 12th St.
SPECIAL REQUIREMENT NO. 2: FLOOD HAZARD AREA DELINE ATION
This project is not located in a flood hazard area.
SPECIAL REQUIREMENT NO. 3: FLOOD PROTECTION FACILIT IES
This project does not modify or use a flood protection facility.
SPECIAL REQUIREMENT NO. 4: SOURCE CONTROL
Source control requirements apply to projects proposing a commercial building or which require a Commercial
Site Development permit. The commercial development will apply the appropriate BMP’s required during
building permits.
SPECIAL REQUIREMENT NO. 5: OIL CONTROL
The project does not classify as a high use site and is thus exempt from the Special Requirement #5.
SPECIAL REQUIREMENT NO. 6: AQUIFER PROTECTION AREAS
The project is within wellhead protection zone 2. However, the project is not proposing any of the drainage
facilities mentioned in Section 1.3.6 of the RSWM and thus special requirement No. 6 is not applicable.

4. Off-Site Analysis
3.1 UPSTREAM ANALYSIS
The site is on a ridgeline. There are no upstream basins that drain onto the project site.
3.2 DOWNSTREAM ANALYSIS
Approximately 90% of the existing development drains to the southwest, where it is collected in the public
conveyance systems within NE 10th St. The Sunset Neighborhood park, directly across NE 10th St, has sized
their bioretention cells to accommodate 0.77 acres of the flow from our site, while the rest of this runoff is
conveyed west along 10th St toward Sunset Blvd. The remaining approximately 10% of existing runoff flows, to
the north, where it discharges to the public stormwater conveyance system within NE 12th St. Flow from all of
three of these discharge locations converge within ¼ mile downstream.
The downstream path for this site’s runoff is contained within a piped public conveyance system.
Approximately 1 mile downstream, the piped system crosses under Interstate 405 and outfalls into a series of
wetlands. Runoff flows through the wetlands until it reaches a creek which flows to Lake Washington. The
Sunset Area Storm Water Master Plan notes that there are no known capacity issues in the drainage system
downstream of our site.

Appendix A
5. Flow Control Analysis and Design
According to the Flow Control Application Map the project falls within the Peak Flow Control Standard (Existing
Site conditions) Region (see Appendix B). This standard states that the 2, 10 and 100 yr peak flows for
developed conditions must be less than peak flows that existed on site prior to May 1979.
The King County Assessor’s Reports indicate that the latest improvements to the developed parcels were
made in 1977. Street frontages being improved (Sunset Blvd, Harrington Pl, Kirkland Avenue NE, and NE 12th
St) were all assumed to their current condition prior to the on-site parcels. See Figures 4-1 and 4-2 for a
comparison of impervious and pervious surfaces in the existing and developed conditions. For this reason
existing surveyed conditions were modeled as existing conditions in this analysis.
Figure 5-1: Predeveloped Areas
KPFF Consulting Engineers

Figure 5-2: Developed Areas
Table 5-1: MGS Flood Peak Flow Rate Results
The proposed improvements to the site will create more pervious surface than existed in May 1979. As a
result, without the implementation of any flow control measures, te developed peak flows are less than
predeveloped peak flows in the 2, 10 and 100yr condition – complying with Core Requirement #3.
Predeveloped Peak Flows Developed Peak Flows
2 yr 4.35 cfs 3.92 cfs
10 yr 6.42 cfs 5.90 cfs
100 yr 11.34 cfs 10.64 cfs

6. Water Quality Analysis and LID Performance Standard
Design
The project is proposing to construct infiltrating bioretention cells to satisfy both Core Requirement No. 8
Water Quality and Core Requirement No. 9 On-site BMPs.
6.1 WATER QUALITY REQUIREMENT
Over 50% of the developed site will be commercial and multifamily land use. According to the RSWM this
triggers the need for Enhanced Basic Water Quality treatment. The treatment goal of Enhanced Basic Water
Requirement can be achieved by treating targeted surface runoff with bioretention (Enhanced Basic Option 4,
6.1.2 RSWM).
The project site has been subdivided into 67 sub-basins (Figure 5-1)
Figure 5-1: Surface Runoff Basins
The grading approach in each of these sub-basins is such that runoff will sheet flow from new PGIS and drain
through a curb cut into a bioretention facility. Runoff will be treated in the bioretention cells and infiltrate into
native soils. Additionally, the surface runoff from street frontage improvements will be treated using
bioretention cells (basins 47-56). Bioretention facilities have been sized using MGS Flood methodology to treat
91% of runoff entering the cell. An infiltration rate of 6 in/hr was used for the amended soil and an infiltration
rate of 0.7 in/hr was used for the underlying native soils consistent with infiltration test results completed by
Earth Solutions Northwest LLC (report in Appendix C). It should be noted that the 0.7 in/hr is a conservative
infiltration rate. Rates ranging from 2 in/hr – 20 in/hr were tested on site, but the lowest rate was used along
with a correction factor to. The MGS Flood Report demonstrating compliance is located in Appendix B.

6.2 ON-SITE BMP REQUIREMENT
According to section 1.2.9 of the RWSM, Core Requirement #9 can be satisfied by,
1) application of BMPs to the maximum extent feasible
2) or by using a continuous runoff model to demonstrate compliance with the Low Impact Development
(LID) Performance Standard.
This development has opted to use the LID performance Standard. In order to comply with this standard,
“Stormwater discharges shall match developed discharge durations to pre-developed durations for the range
of pre-developed discharge rates from 8% of the 2-year peak flow to 50% of the 2-yr peak flows.” The pre-
developed condition is modeled as forested in this approach. The development has proposed to meet this
requirement primarily through bioretention cells distributed throughout the site. Using the same basins,
bioretention areas and infiltration rates as for Water Quality in section 6.1, duration flows, for each basin, were
modeled using MGS flood methodology. Each individual basin’s duration flows were found to be compliant with
the aforementioned LID standards.
Overflow from each basin will tight line to the public conveyance system. The bioretention cell network
functions in parallel not in series, and all site discharge converges within 0.25 miles downstream; therefore the
area inputs and bioretention areas for each basin were summed to develop a single basin and single a point of
compliance for the purposes of demonstrating satisfaction of the on-site BMP requirement. A single site basin
flowing to a single bioretention cell was modeled and demonstrated to be compliant with LID and Water Quality
standards for the site as a whole. Each individual basin’s MGS Flood Reports as well as the composite MGS
Flood report is provided in Appendix B.
6.3 ON-SITE BMP MIXED USE LOTS
Mixed-use lots will use a combination of green-roof and ground level bio-retention planters to achieve 100% of
the LID performance standard. Meeting this requirement strictly through the use of bio-retention planters
would require approximately 2,900 square feet and 2,200 Square feet of planter area on mixed Use Parcel A
and B respectively. The preliminary drainage plan demonstrates that area in excess of this amount is available
adjacent to the building structures. The mixed use parcels areas were included in the basin representing the
entire site described in Section 6.2. The actual BMP sizing and placement will be refined and fully
documented through individual site plan entitlements for each mixed-use parcel.
7. Conveyance System Analysis and Design
No existing capacity issues are known within the downstream conveyance system. A detailed analysis will be
performed for the projects receiving conveyance system during construction document permitting. Proposed
conveyance system elements, both onsite and offsite, shall be analyzed, designed and constructed according
to RSWM requirements. Conveyance system calculations will be provided during construction document
permitting following entitlement.
8. Esc Analysis and Design
Erosion and Sediment Control measures and Stormwater Pollution Prevention and Spill Control measures will
be applied through a Construction Stormwater Pollution Prevention (CSWPP) plan.

9. Special Reports and Studies
The Sunset Area Surface water Master Plan (CH2M HILL, 2011) discusses the City of Renton’s surface water
management program within the Sunset Area. The Master Plan requires this project to install an 8’ bioretention
facility along the south side of NE 12th St.
10. Bond Quantities and Declaration of Covenant
Bond quantities for the City of Renton will be provided prior to construction permitting.
