Villages of La Costa
Evaluation of Hillside Impacts
A) Development of Natural Slopes over 40 YO Gradient
Neighborhood Impacts of Significance Mitigation
1.9 Minor impact into qualifying not significant Vest HCP open space
Level Proposed
of 40% or more and do not fall Provide erosion control,
under one of the exemptions. It landform landscape and
was anticipated that in the SWPP
preservation of HCP open space
and proposed additional HCP open
space such as this would occur and
that and modification to hillside
standards.
1.14 Proposed lots impact to slopes not significant Erosion control per City
1.15 40% meets the exemption criteria Ordinance, landform
1.16' for slopes under 10,000 sf meets exclusion per landscape & SWPPP
21.95.120
B) Volume of Grading
The volume of grading for the Villages of La Costa falls oin the potentially acceptable range and its
impacts are potentially signifacant. The mitigation proposed is erosion control per City Ordinance,
implement landform landscaping, contour grading, vest open space, single story units and provide SWPPP.
Grading Analysis
Total Raw Grading Quantities No import or export of material is proposed
4,620,000 Cut 4,620,000 Fill 439.8 Acres
10,500 cytac
Exclusions per section 21.95.130
Circulation and Collector Streets

15,650 cytacre
Project Total 3,960,000 Cut 3,690,000 Fill 397.6 Acres
Potentially Acceptable 9,960 cylacre
C) Slope Height, 40’ High Slopes

Slope over 40’ adjacent to not significant
Poinsettia Lane meets the
exemption criteria for exempt per 2 1.95.130
circulation element streets
Slope over 40’ adjacent to not significant
Alicante extension meets the
exemption criteria for exempt per 21.95.130

1.12 Slope over 40’ to match not significant
existing Zodiac Drive and
preserve open space
D) Contour Grading
Level
Neighborhood Impacts of Significance
1 .A Slopes along Alicante and not significant
1 .B Poinsettia Lane are curve-linear
1.9 and contour grading where meet city standard
1.12 possible. Additional contouring
would decrease the proposed
addition of HCP open space or
extend slopes over 40’ height limit.
1.6 Slopes along Alicante meets the not significant
requirements for contour grading
With varying slope gradients and
undulation.
1.8 Slopes along sensitive wetlands not significant
1.17 and proposed additional HCP
open space. Curve-linear and
contour grading would decrease
additional open space.
